Abstract
A method for applying a spray texture material to a wall surface utilizing an aerosol container for the texture material, along with discharge tubes through which the material is dispensed. By using tubes of different cross-sectional area, the spray patterns of the material can be made with smaller and larger particle size within more precisely controlled limits.
Description
209~1~3 SPRAY l~xlu~ING APPARATUS ~ND MET~OD
The present invention relate~ to the art of spray texturing, and more particularly to an apparatus and method by which spray texturing can be accomplished to provide spray patterns of varying te~ture (i.e~ with either ~iner or more coarse particle size).
Background of the Invention When drywall panels are installed in a building, and the seams taped, prior to painting the wall surface, there is often applied a spray texture, which is followed by painting. The spray texture will provide a desirable background pattern, and also obscure some of the seams that might appear in the drywall surface.
There are in the prior art various spray texturing tools or devices which utilize pressurized air to spray the texture material onto the wall surface.
Some of these use compressed air as the gaseous medium to spray the textured material, with the pressurized air being derived from a remote source that ~eeds the air ~ through a hose to the tool~ There are also tools which ; are totally handheld, with the pressurized air being produced by manually reciprocating the piston o~ an airpump that is built into the tool.

texture surface treatment that would make it match with the surrounding drywall surface. It is, of course, desirable to have the spray pattern on the patch match that of the surrounding surface.
Also, when a rather small "patch" of drywall is to be spray textured, there is the matter of convenience.
One approach has been simply to provide the spray texture material in an aerosol can, and the textured ma~erial is dispensed directly from the can to be sprayed onto the drywall surface. However, one of the considerations is how this can be accomplished in a manner to provide proper matching of the texturé with that which is on the surrounding drywall.
U.S. 5,037,011 (Woods) discloses such an aerosol texture spraying device where the spray texture material is dispensed directly from the nozzle of the aerosol can.
In a commercial embodiment of a device such as this, when there is higher pressure in the container, there is a relatively fine spray pattern. For a more coarse pattern (i.e. with larger particle sizes), the can is inverted and the nozzle depressed to dispense a certain amount of the propellant gas ~or a few seconds. Then the can is turned upright and the spray texture material dispensed at a lower pressure to provide the spray pattern with lzrgcr pzrticle sizes.

Summary of the Invention The object of the present invention is to provide a method and apparatus by which a spray texture can be applied to a wall surface, such as a drywall surface, with the character of the spray pattlern, in terms of particle size and consistency, being accomplished with greater precision and uniformity.
Further, it is an object to accomplisb this in a manner that one section of a wall surface can be sprayed with a texture material that matches more closely a surrounding, existing textured surface. It is a further object to provide a method and apparatus which can be accomplished quite conveniently utilizing an aerosol lS container to discharge the spray texture material.
In the method of the present invention, there is ; provided an apparatus to discharge a spray texture material through a nozzle means having a nozzle discharge opening to dispense this material. There is further provided a first delivery tube means having a first discharge passageway o~ a first predetermined cross-sectional area. The material discharge apparatus is operated to cause the textured material to be discharged through the tube means.
Then a second discharge tube means is positioned to receive material from the discharge nozzle means, and this second tube means has a second discharge passageway with a seaond predetermined cro~s-sectional area di~orent ~rom ~h~ fir~t cross-saational araa.

Description of the Preferred EmkQdimsh~
In Figure l, there is shown the apparatus 10 of the present invention being used in spraying the texture material onto a section of wallboard 12 having a previously sprayed surfac~ portion 14 surrounding an unsprayed portion 16 which could be, for example, a more recently applied piece of wallboard that serves as a ~patchn. The spray itself is indicated at 18, and the spray material deposited on the wall portion 16 as a sprayed taxture is indicated at 20.
With reference to Figure 2, the present invention is shown being incorporated with an aerosol spray :: containing device 22, the basic design of which is or may : 15 be conventional in the prior art. Used in combination : with this container 22 is a dispensing tube 24 which~is a critical feature of the present..invention~ More particularly, it has been foun~ by utilizing this . dispensing tube 24 in particular arrangements to discharge the spray texture material, more precise control of the spray texture pattern can be achieved.
Further, there are other advantages, in that not only is : a more controllable spray pattern achieved, but th~s.
consistency of the spray pattern can be accomplished for a relatively long period of use. In other words, even after a substantial amount of the spray texture material has been already discharged from the aerosol dispensing container 22, the spray pattern remains rather cons1stent. ~he manner in which this is achieved will be de~crlbed morc ~ully later herein.

It is recognized that in the prior art tubular members have been used in combination with an aerosol spray can to deliver a ma~erial, such as a lubricant. To the best knowledge of the applicants, however~ ~his use has been primarily to enable the aerosol container to deliver the fluid, such as a lubricating oil, to a somewhat inaccessible location, and not to achieve the ends of the present invention.
To return to our description of the aerosol dispensing device 22, as indicated aboveJ the basic design is or may be conventional. As shown herein, the device 22 comprises a cylindrical container ~ and a dispensing nozzle member 28 positioned at the top of the container 26 As is common in the prior art, this dispensing member 28 in its upright position blocks flow of material from the container 26. This dispensing member 28 is attached to a downwardly extending s~m 30, ~ and when the member 28 is depressed, a valve opens within - the container 22 so that the material in the container 22 flows upwardly through the stem 30 and laterally out a nozzle for~ed in the dispensing nozzle member 28. Since the manner in which this is achieved is well known in the prior art, this will not be described in detail herein.
; Reference is now made to Figures 16 through 18, and it can be seen that the stem 30 provides a passageway 32 through which the spray texture material flows ; upwardlyr and then is directed laterally to be discharged through a lat~ral nozzle opening 34. The passageway 32 .

.. , In the present invention, the nozzle member 28 is provided with a counterbore 36 having a moderately enlarged diameter, relative to the diameter of the nozzle opening 34. Both the nozzle opening 34 and ~he counter-bore 36 have a cylindrical configuration~ The dispensingtube 24 has an outside diameter so that its end portion is able to fit snuggly within the counter-bore 36, with the end surface of the tube 34 bearing against the forwardly facing annular shoulder 38 defined by the counterbore 36 with the nozzle opening 34.
In the preferred embodiment of the present invention, a plurality of dispensing tubes 24 are provided, and in the present embodiment, there are three such tubes, 24a~ 24b and 24c. It can be seen from examining Figures 3, 5 and 7 ~and also Figures 16, 17 and 18~ that the outside diameter of all three tubes 24a, 24b, and 24c have the same outside diameter, but different inside diameters for the discharge passageway 40.
2~ It has been found that by selecting different diameters for the discharge passageway 40, the spray texture pattern can be controlled more accurately. With the smaller dia~eter 40a o~ the discharge tube 24a, shown in Flgure 3, a relatively fine spray texture pattern can be achieved, as shown in Figure 4, where the particles of spray texture material are of a small particle size, as shown in the wall section 42a..
In Figure 5, the interior discharge passageway 40b is o~ a mo~e interm~diate size, and thi9 results in a discharge pattern whlch has a somewhat lar~er paxticle size, as sbown in the wall seation ~2b~ ~hen, with the ., .

With regard to the spray texture material itself, if has been found that quite desirable results can be achieved where the basic composition of the spray texture material comprises a resin or resins, particula~e filler material and a propellant. Also, there is a solvent, and desirably dryers to accelerate the drying reaction of the resin with oxygen.
More specifically, the resin or resins desirably comprise alkyd resins, and more specifically those which are generally called bodying alkyds or puffing alkyds~
Such alkyds are sometimes used for what are called narchitectural coatingsn. The resins are made somewhat more gelatinous than would be used in other applications, this depending upon the spray characteristics that are desired. If the alkyd resins are made more gelatinous or viscous, a coarser spray pattern would be expected for a particular set of conditions.
The particulate filler material desira~ly has various particle sizes, and this can be a ~iller material or materials which are well known in the prior art, such as calcium carbonate, silica, talc, wollastonite, various types o~ pigments, etc.
The propellant ls desirably a liquified ~ hydrocarbon gas, with this liquified gas heing dispersed ; 30 throughout the texture materiar~ composi~ion, su~h as , bein~ dissolved ~herein or oth~rwise dispersed ~herein.

The propellant is characteri~ed that under the higher pressure within the container the propellant remains dispersed or dissolved as a liquid throughout the spray texture material, and upon release of pressure, the propellant begins going back to its gaseous form to act as a propellant and push the material up the stem passageway 32 and out the nozzle opening 34.
m e solvent is desirably aromatic and/or aliphatic hydrocarbons, ketones, e~c.
10The dryer or dryers would normally be metallic dryer, such as various metal salts. These are already well known in the art, so these will not be described in detail herein.
It has been found that this type of texture lS material can be sprayed by using the present invention to provide a reasonably consistent spray texture for a given configuration of the tube 24. Also, it has been found ~; that this consistency of spray pattern can be accomplished throughout the discharge of the great majority of the spray texture material within the container 26.
- With reg~rd to the particular dimensions utilized in this preferred embodiment of the present invention, i reference is made to Figures 16 through 18. The diameter "d" of the nozzle orifice 34 is in this particular embodiment 0.102 inch, and the diameter of the counter-bore (indicated at "e") is 0.172 inch; the diameter "f"
of the passageway 40a ~i.e. the smallest diameter passagewa~ 0~050 inch7 the diameter "g" o~ the inter-edi~te 9iz~d passa~eway 40b ~see Figure 17) is :'~
.
, . , ,.
2 0 ~
0.095 inch; and the diameter "h" of the largest tube passageway 40c is 0.145 inch.
Thus, it can be seen in the arrangements cf Figures 16 through 18 that in Figure 16, there is a substantial reduction in the cross-slectional area of the passageway 40a, with this having about one half the diame~er of the nozzle opening 34, S3 that the passageway ; area 40a is about one quarter of the nozzle opening 34.
In the intermediate size of Figure 17~ the diameter and cross-sectional area of the passageway 40b (indicated at "gn) is nearly the same as that of the ;~ nozzle 34.
In Figure 18, the diameter of the passageway 40c (indicated at "hn) is slightly less than one and one half -~ 15 of the nozzle opening 34, and the cross sectional area is about twice as large.
Figures 9, 10 and 11 show an alternative form of the tubes 24a-c, and these tubes in Figure 9 through 11 (designated 24a', 24b' and 24c') have the same internal passageway cross-sectional area as the passageways 24a, 24b and 24c, respectively, but the outside diameter of these are made smaller, relative to the passageway size.
I~ there is such varying outside diameters, then a plurality of mounting collars could be used, with these having consistent outside diameters, but varying inside diameters to ~it around at least the smaller tubes of Figures 9 and 10.
Figures 12 through 14 are simply shown to ; lllustrate that khe leng~h o~ the tube 24 can be varied.

tube length could be used, in general there is no particular advantage in doing so since the proper consistency can be obtained with a tube of about four inches. Also, experiments have indicated that the length of the tube 24 can be reduced lower than four inches, possibly to two inches and even as low as one inch) without causing any substantial deterioration of the consistency and quality of the formation of the spray pattern. ~owever, it has been found that somewhat more consistent results can be obtained if the length of the tube 24 is greater than one inch and at least as great or ; greater than two inches.
A tube length as short as one half inch has been tried, and this is able to provide a substantial improvement of performance over what would have been obtained simply by discharging the spray texture directly from the nozzle opening 34, without any tube, relative to controlling spray pattern. The shorter tube 24 (as small as one half inch) provides a significant benefit, but not the full benefit of the longer tube 24. The ~ery short tube (e.g. one half inch) has a lesser quality of performance when used with the larger diameter passageway 40 than with the smaller passageway.
Figure 15 illustrates that the texture pattern can also be controlled to some extent by moving the apparatus 10 closer to or farther away from the wall surface. If the apparatus 10 is moved rather close to the wall surface, the density of the applied material is incr~ased ~or a given time oE exposure~ It has been ~ound that in gene~al ~a~i5facto~y resu;lts can he ob~ained i~ th~ appara~us 10 i3 held approximatel~ ~hr~e .~

~eet from the wall surface. Xowever, this will depend upon a number of factors, such as the pressure provided by the propellant, the character of the spray texture material, and other factors.
To describe now the operation of the present invention, an aerosol dispensing device 22 is provided as described previously herein with the spray texture material contained wîthin the can 26 a~ a desired pressure. As is common with aerosol cans, it is desirable to shake the device 22 for a few seconds prior to depressing the nozzle control member 28.
If a relatively ~ine texture is desired, then a ;~ smaller diameter tube such as at 24a is used. For spray texture patterns having larger particle size, the larger diameter tube is used.
The person directs the nozzle opening 34 and the tube 24 toward the wall surface to be sprayed and depresses the nozzle member 2~. As the spray texture ; material is discharged, the container 26 is moved back and forth and is tilted to different angles to spray the desired area.
As indicated earlier, it has been found that not only can a "fineness" or "coarseness" (i.e. smaller particle size or larger particle size, respectively) be controlled with reasona~le precision by the present invention, but this consistency of the spraying pattern can be maintained throughout the discbarge of the great majority o~ the spray material within the container 26.
While these phenomena are no~ totally understood, it i~
believed ~hat the Pollowlng can be reasonably h~po~he~ized t~ provid~ at least a partial explanatlon.

- ~ , First, ~he separation of the texture material into particles of smaller or larger si~e is due in part to the character of the material itself, and also due in part to the way the forces are exerted on the material to tend to break it up into particles. More particularly, it can be hypothesized that if there is a greater shear force tending to separate the particLes, it would be expected that there would be a finer pattern.
It is also recognized that when a fluid is moving through a conduit or tube, there is commonly what is called a velocity gradient along a transverse cross section of the flow of material. More precisely, the material immediately adjacent to the wall surface may have a very low velocity or practically no velocity. The adjacent material just a small distance away from the wall will have a somewhat greater velocityr but will ~ still be retarded signi~icantly due to the shear force - provided by the material that is closer to the wall surface. As the cross section of the liquid material is analyzed closer toward the center, the shear force becomes less and the velocity becomes more uni~orm.
With the ~oregoing in mind, it also has to be ; recognized that if the diameter of the tube or conduit is reduced by one half, the cross-sectional area is reduced by one ~uarter. Thus, for the smaller tube (i.e. one half diameter~ the surface area that provides a retarding force is doubled relative to the volume of flow at the same velocity). ~h i5 would indicate that ~or a given ~ross-~a~ional ~egment o~ the fluid materlal being dlscharg~d, tbere i~ rclatively greater shea~ ~orce o~erted ~or the small-x in~ide diameter tube. ~his would : , ~' ' 2 ~
lead to the conclusion that for the discharge of a given amount of fluid at a certain velocity and at ~he same pressure, there would be a smaller particle size than if a tube of greater inside diameter were used.
Another phenomenon to be considered is with regard to the pressure which is forcing the textured material out of the tube 24. It can be surmised that if the pressure is greater, the velocity of the material traveling through the tube 24 would be greater, so that the shear forces exerted on the texture material would be greater so that smaller particle sizes would result.
It can be seen in Figure 16 that the rela~ively small diameter passageway 40a serves as a restriction for the material flowing out the no~zle 34. This wo~lld tend to cause the velocity of the material flowing up the stem passageway 32 and out the nozzle opening 34 to decrease to some extent, but to have a relatively higher velocity - out the passageway 40a. Further, it can be expected that the pressure of the propelling gas in the passageway 40a would be somewhat higher than if a larger diameter passageway such as 40b or 40c were utilized. Experi mental results using different si~e tubes seem to verify this conclusion.
In Figure 17, the diameter and cross-sectional area of the passageway 40b is nearly the same as that o~
the nozzle opening 34. Therefore it can be surmised that the velocity and pressure in the passageway 40b would be somewhat less than in the passageway 40a, this resulting i~ a somewhat larger particle size, and al~o a somewhat 3~ lower dis~harge veloaity. Exparimental result~ have veriPied thl~ al~o.
2~39~3 ~
Finally, with reference to Figure 18, when the passageway diameter is larger than that of the nozzle opening 34 (as it is with the passageway 40c), it can be ; expected that the fluid discharged from the nozzle 34 5 would have a lower velocity and that there would be a lower propelling force provided by the propellant.
Experimental results have indicated that this results in the coarser particle size.
However, it has to be recognized that while the 10 above hypothesis can be proposed with reasonable justification, there are likely other phenomena involved which the applicants are either not aware of or have not fully evaluated. For example, with the propellant being disbursed in (and presumably dissolved in) the texture 15 compositlon, it can be surmised that this propellant continues to go out of solution or dispersion into its gaseous form and expand to provide the propelIant force, and this continues as the quantity of texture material continues to be reduced. This may also have a desirable 20 effect on the formation of the particles and of the particle size, relative to consistency.
Nevertheless, regardless of the accuracy or correctness o~ the above explanations, it has been found that with ~he present invention, the spray pattern (and 25 more particularly the particle size of the spray pattern) ~an be achieved with greater consistency and within ; relatively greater limits of particle size, than the prior art devices known to the applicants. Further, the consistency o~ the spray pattern can be maintained ~or 30 ~he discharge o~ a large proportion of sp~ay texture material ~rom th~ appara~us 10.

2 ~ a It is to be recognized, o~ course~ that various relative dimensions could be changed withou~ departing from the basic teachings of the presen~ invention. For example, it has been found that with spray texture material of a character which are acceptable in present day use, that a range of tube insiae diameters of approximately one half of a tenth of an inch to one and one half tenth of an inch would give a reasonable range of texture spray patterns. However, it can be surmised that tube diameters outside of this range (e.g. one guarter of a tenth of an inch to possibly as high as one quarter of an inch would also provide acceptable texture spray patterns, depending upon a variety of circumstances, such as the viscosity and other lS characteristics of the spray texture material itself, the discharge pressure, the volumetric rate at which the spray texture material is delivered to the tube 24, and other factors.
It is to be recognized that various modifications can be made without departing from the basic teaching of the present invention A

Desirably, the cross-sectional area of the passageway means is equivalent to a cross-sectional circular area with a given diameter, with a given diameter being between one quarter of a tenth of an inch and one quarter of an inch.

Description of the Preferred EmkQdimsh~
In Figure l, there is shown the apparatus 10 of the present invention being used in spraying the texture material onto a section of wallboard 12 having a previously sprayed surfac~ portion 14 surrounding an unsprayed portion 16 which could be, for example, a more recently applied piece of wallboard that serves as a ~patchn. The spray itself is indicated at 18, and the spray material deposited on the wall portion 16 as a sprayed taxture is indicated at 20.
With reference to Figure 2, the present invention is shown being incorporated with an aerosol spray :: containing device 22, the basic design of which is or may : 15 be conventional in the prior art. Used in combination : with this container 22 is a dispensing tube 24 which~is a critical feature of the present..invention~ More particularly, it has been foun~ by utilizing this . dispensing tube 24 in particular arrangements to discharge the spray texture material, more precise control of the spray texture pattern can be achieved.
Further, there are other advantages, in that not only is : a more controllable spray pattern achieved, but th~s.
consistency of the spray pattern can be accomplished for a relatively long period of use. In other words, even after a substantial amount of the spray texture material has been already discharged from the aerosol dispensing container 22, the spray pattern remains rather cons1stent. ~he manner in which this is achieved will be de~crlbed morc ~ully later herein.

.. , In the present invention, the nozzle member 28 is provided with a counterbore 36 having a moderately enlarged diameter, relative to the diameter of the nozzle opening 34. Both the nozzle opening 34 and ~he counter-bore 36 have a cylindrical configuration~ The dispensingtube 24 has an outside diameter so that its end portion is able to fit snuggly within the counter-bore 36, with the end surface of the tube 34 bearing against the forwardly facing annular shoulder 38 defined by the counterbore 36 with the nozzle opening 34.
In the preferred embodiment of the present invention, a plurality of dispensing tubes 24 are provided, and in the present embodiment, there are three such tubes, 24a~ 24b and 24c. It can be seen from examining Figures 3, 5 and 7 ~and also Figures 16, 17 and 18~ that the outside diameter of all three tubes 24a, 24b, and 24c have the same outside diameter, but different inside diameters for the discharge passageway 40.
2~ It has been found that by selecting different diameters for the discharge passageway 40, the spray texture pattern can be controlled more accurately. With the smaller dia~eter 40a o~ the discharge tube 24a, shown in Flgure 3, a relatively fine spray texture pattern can be achieved, as shown in Figure 4, where the particles of spray texture material are of a small particle size, as shown in the wall section 42a..
In Figure 5, the interior discharge passageway 40b is o~ a mo~e interm~diate size, and thi9 results in a discharge pattern whlch has a somewhat lar~er paxticle size, as sbown in the wall seation ~2b~ ~hen, with the ., .

With regard to the spray texture material itself, if has been found that quite desirable results can be achieved where the basic composition of the spray texture material comprises a resin or resins, particula~e filler material and a propellant. Also, there is a solvent, and desirably dryers to accelerate the drying reaction of the resin with oxygen.
More specifically, the resin or resins desirably comprise alkyd resins, and more specifically those which are generally called bodying alkyds or puffing alkyds~
Such alkyds are sometimes used for what are called narchitectural coatingsn. The resins are made somewhat more gelatinous than would be used in other applications, this depending upon the spray characteristics that are desired. If the alkyd resins are made more gelatinous or viscous, a coarser spray pattern would be expected for a particular set of conditions.
The particulate filler material desira~ly has various particle sizes, and this can be a ~iller material or materials which are well known in the prior art, such as calcium carbonate, silica, talc, wollastonite, various types o~ pigments, etc.

The propellant is characteri~ed that under the higher pressure within the container the propellant remains dispersed or dissolved as a liquid throughout the spray texture material, and upon release of pressure, the propellant begins going back to its gaseous form to act as a propellant and push the material up the stem passageway 32 and out the nozzle opening 34.
m e solvent is desirably aromatic and/or aliphatic hydrocarbons, ketones, e~c.
10The dryer or dryers would normally be metallic dryer, such as various metal salts. These are already well known in the art, so these will not be described in detail herein.
It has been found that this type of texture lS material can be sprayed by using the present invention to provide a reasonably consistent spray texture for a given configuration of the tube 24. Also, it has been found ~; that this consistency of spray pattern can be accomplished throughout the discharge of the great majority of the spray texture material within the container 26.
- With reg~rd to the particular dimensions utilized in this preferred embodiment of the present invention, i reference is made to Figures 16 through 18. The diameter "d" of the nozzle orifice 34 is in this particular embodiment 0.102 inch, and the diameter of the counter-bore (indicated at "e") is 0.172 inch; the diameter "f"
of the passageway 40a ~i.e. the smallest diameter passagewa~ 0~050 inch7 the diameter "g" o~ the inter-edi~te 9iz~d passa~eway 40b ~see Figure 17) is :'~

2 0 ~
0.095 inch; and the diameter "h" of the largest tube passageway 40c is 0.145 inch.
Thus, it can be seen in the arrangements cf Figures 16 through 18 that in Figure 16, there is a substantial reduction in the cross-slectional area of the passageway 40a, with this having about one half the diame~er of the nozzle opening 34, S3 that the passageway ; area 40a is about one quarter of the nozzle opening 34.
In the intermediate size of Figure 17~ the diameter and cross-sectional area of the passageway 40b (indicated at "gn) is nearly the same as that of the ;~ nozzle 34.
In Figure 18, the diameter of the passageway 40c (indicated at "hn) is slightly less than one and one half -~ 15 of the nozzle opening 34, and the cross sectional area is about twice as large.
Figures 9, 10 and 11 show an alternative form of the tubes 24a-c, and these tubes in Figure 9 through 11 (designated 24a', 24b' and 24c') have the same internal passageway cross-sectional area as the passageways 24a, 24b and 24c, respectively, but the outside diameter of these are made smaller, relative to the passageway size.
I~ there is such varying outside diameters, then a plurality of mounting collars could be used, with these having consistent outside diameters, but varying inside diameters to ~it around at least the smaller tubes of Figures 9 and 10.
Figures 12 through 14 are simply shown to ; lllustrate that khe leng~h o~ the tube 24 can be varied.

tube length could be used, in general there is no particular advantage in doing so since the proper consistency can be obtained with a tube of about four inches. Also, experiments have indicated that the length of the tube 24 can be reduced lower than four inches, possibly to two inches and even as low as one inch) without causing any substantial deterioration of the consistency and quality of the formation of the spray pattern. ~owever, it has been found that somewhat more consistent results can be obtained if the length of the tube 24 is greater than one inch and at least as great or ; greater than two inches.
A tube length as short as one half inch has been tried, and this is able to provide a substantial improvement of performance over what would have been obtained simply by discharging the spray texture directly from the nozzle opening 34, without any tube, relative to controlling spray pattern. The shorter tube 24 (as small as one half inch) provides a significant benefit, but not the full benefit of the longer tube 24. The ~ery short tube (e.g. one half inch) has a lesser quality of performance when used with the larger diameter passageway 40 than with the smaller passageway.
Figure 15 illustrates that the texture pattern can also be controlled to some extent by moving the apparatus 10 closer to or farther away from the wall surface. If the apparatus 10 is moved rather close to the wall surface, the density of the applied material is incr~ased ~or a given time oE exposure~ It has been ~ound that in gene~al ~a~i5facto~y resu;lts can he ob~ained i~ th~ appara~us 10 i3 held approximatel~ ~hr~e .~

~eet from the wall surface. Xowever, this will depend upon a number of factors, such as the pressure provided by the propellant, the character of the spray texture material, and other factors.
To describe now the operation of the present invention, an aerosol dispensing device 22 is provided as described previously herein with the spray texture material contained wîthin the can 26 a~ a desired pressure. As is common with aerosol cans, it is desirable to shake the device 22 for a few seconds prior to depressing the nozzle control member 28.
If a relatively ~ine texture is desired, then a ;~ smaller diameter tube such as at 24a is used. For spray texture patterns having larger particle size, the larger diameter tube is used.
The person directs the nozzle opening 34 and the tube 24 toward the wall surface to be sprayed and depresses the nozzle member 2~. As the spray texture ; material is discharged, the container 26 is moved back and forth and is tilted to different angles to spray the desired area.
As indicated earlier, it has been found that not only can a "fineness" or "coarseness" (i.e. smaller particle size or larger particle size, respectively) be controlled with reasona~le precision by the present invention, but this consistency of the spraying pattern can be maintained throughout the discbarge of the great majority o~ the spray material within the container 26.
While these phenomena are no~ totally understood, it i~
believed ~hat the Pollowlng can be reasonably h~po~he~ized t~ provid~ at least a partial explanatlon.

- ~ , First, ~he separation of the texture material into particles of smaller or larger si~e is due in part to the character of the material itself, and also due in part to the way the forces are exerted on the material to tend to break it up into particles. More particularly, it can be hypothesized that if there is a greater shear force tending to separate the particLes, it would be expected that there would be a finer pattern.
It is also recognized that when a fluid is moving through a conduit or tube, there is commonly what is called a velocity gradient along a transverse cross section of the flow of material. More precisely, the material immediately adjacent to the wall surface may have a very low velocity or practically no velocity. The adjacent material just a small distance away from the wall will have a somewhat greater velocityr but will ~ still be retarded signi~icantly due to the shear force - provided by the material that is closer to the wall surface. As the cross section of the liquid material is analyzed closer toward the center, the shear force becomes less and the velocity becomes more uni~orm.
With the ~oregoing in mind, it also has to be ; recognized that if the diameter of the tube or conduit is reduced by one half, the cross-sectional area is reduced by one ~uarter. Thus, for the smaller tube (i.e. one half diameter~ the surface area that provides a retarding force is doubled relative to the volume of flow at the same velocity). ~h i5 would indicate that ~or a given ~ross-~a~ional ~egment o~ the fluid materlal being dlscharg~d, tbere i~ rclatively greater shea~ ~orce o~erted ~or the small-x in~ide diameter tube. ~his would : , ~' ' 2 ~
lead to the conclusion that for the discharge of a given amount of fluid at a certain velocity and at ~he same pressure, there would be a smaller particle size than if a tube of greater inside diameter were used.
Another phenomenon to be considered is with regard to the pressure which is forcing the textured material out of the tube 24. It can be surmised that if the pressure is greater, the velocity of the material traveling through the tube 24 would be greater, so that the shear forces exerted on the texture material would be greater so that smaller particle sizes would result.
It can be seen in Figure 16 that the rela~ively small diameter passageway 40a serves as a restriction for the material flowing out the no~zle 34. This wo~lld tend to cause the velocity of the material flowing up the stem passageway 32 and out the nozzle opening 34 to decrease to some extent, but to have a relatively higher velocity - out the passageway 40a. Further, it can be expected that the pressure of the propelling gas in the passageway 40a would be somewhat higher than if a larger diameter passageway such as 40b or 40c were utilized. Experi mental results using different si~e tubes seem to verify this conclusion.
In Figure 17, the diameter and cross-sectional area of the passageway 40b is nearly the same as that o~
the nozzle opening 34. Therefore it can be surmised that the velocity and pressure in the passageway 40b would be somewhat less than in the passageway 40a, this resulting i~ a somewhat larger particle size, and al~o a somewhat 3~ lower dis~harge veloaity. Exparimental result~ have veriPied thl~ al~o.
2~39~3 ~
Finally, with reference to Figure 18, when the passageway diameter is larger than that of the nozzle opening 34 (as it is with the passageway 40c), it can be ; expected that the fluid discharged from the nozzle 34 5 would have a lower velocity and that there would be a lower propelling force provided by the propellant.
Experimental results have indicated that this results in the coarser particle size.
However, it has to be recognized that while the 10 above hypothesis can be proposed with reasonable justification, there are likely other phenomena involved which the applicants are either not aware of or have not fully evaluated. For example, with the propellant being disbursed in (and presumably dissolved in) the texture 15 compositlon, it can be surmised that this propellant continues to go out of solution or dispersion into its gaseous form and expand to provide the propelIant force, and this continues as the quantity of texture material continues to be reduced. This may also have a desirable 20 effect on the formation of the particles and of the particle size, relative to consistency.
Nevertheless, regardless of the accuracy or correctness o~ the above explanations, it has been found that with ~he present invention, the spray pattern (and 25 more particularly the particle size of the spray pattern) ~an be achieved with greater consistency and within ; relatively greater limits of particle size, than the prior art devices known to the applicants. Further, the consistency o~ the spray pattern can be maintained ~or 30 ~he discharge o~ a large proportion of sp~ay texture material ~rom th~ appara~us 10.

2 ~ a It is to be recognized, o~ course~ that various relative dimensions could be changed withou~ departing from the basic teachings of the presen~ invention. For example, it has been found that with spray texture material of a character which are acceptable in present day use, that a range of tube insiae diameters of approximately one half of a tenth of an inch to one and one half tenth of an inch would give a reasonable range of texture spray patterns. However, it can be surmised that tube diameters outside of this range (e.g. one guarter of a tenth of an inch to possibly as high as one quarter of an inch would also provide acceptable texture spray patterns, depending upon a variety of circumstances, such as the viscosity and other lS characteristics of the spray texture material itself, the discharge pressure, the volumetric rate at which the spray texture material is delivered to the tube 24, and other factors.
It is to be recognized that various modifications can be made without departing from the basic teaching of the present invention A
