July 5, 1966 J. B. SELLERS WATER HOSE ATTACHMENT Filed Jan. 14, 1965 INVENTOR J5. S61 Zens ATTORNEYS United States Patent M 3,259,321 WATER HOSE ATTACHMENT James Barry Sellers, Macon, Ga., assignor of thirty percent to Kenneth Sherman, New York, N.Y. Filed Jan. 14, 1965, Ser. No. 425,505 4 Claims. (Cl. 239310) This invention relates to devices employed for directing fluid substances against objects of various kinds for various purposes and types of treatment, including for removing matter from a surface or adding to a surface, or for imparting a particular finish to at least a portion of such objects.
The invention relates particularly to a combination hose nozzle and container in communication therewith, the latter being for a substance sought to be discharged into the stream passing through said nozzle, and which container includes means by which pressure can be increased therein to cause the ejection of material therefrom.
Various devices have been produced in which a substance has been added to and combined with a liquid and thereafter discharged, but ordinarily where fluid is discharged through a nozzle, auxiliary matter is usually applied separately, as for example in the washing and waxing of an automobile, the introduction of matter such as soap or wax is applied separately into the water sprayed upon the surface and the like, but these devices have involved multiple operations and have been time consuming, expensive, and otherwise subject to criticism.
It is an object of the invention to provide a self-contained disposable unit comprised of a tube-like nozzle of.
a non-flexible nature and of related diameter to a hose through which a stream of water is discharged, such nozzle preferably, although not necessarily, having a relatively flat surface along the exterior of the same with an intermittent soft pliable non-expanding and collapsible container for a liquid concentrate or the like of camel back appearance, as well as a device which is of sufiflciently small size that it can be readily manually manipulated to expel a part of the contents from a container into the stream of water by simply squeezing the container in the hand to force the contents through a pressure sensitive one-way rubber valve or grommet, and with the discharge end of the nozzle slightly constricted to produce a smooth uniformly solid effect with minimum splash.
Other objects and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawing in which:
FIG. 1 is a perspective illustrating one application of the invention;
FIG. 2, an enlarged end elevation;
FIG. 3, an enlarged central longitudinal section on the line 3-3 of FIG. 2;
FIG. 4, an enlarged fragmentary detail of the valve structure;
FIG. 5, a perspective of the structure of FIG. 1 with a filling orifice and plug; and,
FIG. 6, an enlarged fragmentary section on the line 66 of FIG. 5.
Briefly stated the invention is 'a nozzle, of inexpensive material such as plastic, papier-mache, or other substance, for attachment to a hose, to which nozzle is secured a housing or container for matter to be introduced into a fluid, such as water, discharged through the nozzle. Such matter, for example, can be any additional substance to be added to the fluid, such as a compound employed in Washing and waxing surfaces of various kinds, including windows, walls, wall structures, automobiles and the like, or it can be a paint or other substance applied to a surface. The nozzle is of a rigid character of a size to 3,259,321 Patented July 5, 1966 be attached to a water hose and provided with a chamber-forming flexible or collapsible canopy type container adapted to fit over the top of the same and in relatively tight contact with the nozzle with a passage containing a self-closing valve providing communication between such chamber and the interior of the nozzle whereby concentrate in the chamber may be expelled into a stream of Water passing through the nozzle by simply squeezing the bulk-like container sufficiently to force the concentrate through the valve, the discharge end of the nozzle being reduced slightly to cause the water being discharged either with or without the concentrate therein to have a generally round non-splashing effect upon the impingement of the water on the surface being washed.
With continued reference to the drawing, a hose nozzle 10 is provided having internal threads 11 for attachment to a water hose 12. The nozzle ltl has an intermediate portion 13 terminating in a discharge end portion 14. The bore or passage within the nozzle is of uniform character, except for an internal projection 15 with an open ing 16 in communication wtih a larger cavity in which is located a valve 18, having self-closing slit 19.
The nozzle may be composed of inexpensive material and produced in any well known manner such as plastic, coated or impregnated papier-mache, rubber, Fiberglas, or any other substance. The nozzle preferably is provided with a saddle type enlargement or reinforcement 29 having a flat surface 21 over which is attached in any desired manner, as for example by fusing or adhesive 22, a container 23 of material which can be readily compressed or distorted without expanding, thus to employ pressure within the container to force fluid through the valve slit 19. This pressure may be applied, for example, by placing the thumb 24 upon the container with the fingers 25 on the opposite side of the nozzle from the thumb and pressure applied to eject a portion of the contents of the container into a stream of water 26 as indicated by the dot-dash arrows 27. If desired the nozzle may have a roughened or knurled portion 28 to facilitate gripping including during connection to the hose 12.
In FIGS. 5 and 6 is disclosed the structure of the preceding figures with an opening 29 in the container 23 with a reinforcing collar 30 about the same, such opening being provided with a closure plug 31 attached by a strap 32 to the container 23. The end of the closure plug which extends into the container is relatively thin, soft and concave so that it will be enlarged upon application of pressure thereto. Due to the shape of such head when the thumb is pressed on the container as illustrated in FIG. 3, the plug 31 will seal the opening 29 and cause ejection through the one-way valve 18 and opening .16 into the nozzle. By removing the plug or closure 31 the device can be refilled and reused.
The invent-ion contemplates the use of a liquid containing any desired substance sought to be introduced into water or other fluid discharged through the nozzle, and this may include chemical substances of various kinds for pest control, fertilization, cleansing, or the like.
The invention may be used in many ways, as for example, for wetting a surface to be washed, directing a stream of water through the nozzle onto the surface without the introduction of anything thereint-o, and. thereafter by compressing the container :to introduce liquid from the container attached to the nozzle thereby forcing a desired amount of such liquid into the stream expelled onto the surface. It is contemplated that the stream of Water may be taken away from the surface being treated, and such surface stnoked with the hand or with a sponge, cloth or the like to dislodge matter adhering thereto, and thereafter the stream of water without any substance from the container admitted thereinto may be redirected onto the surface to rinse the latter.
The container 23 may be composed of any suitable material, including modern plastics, papier-mache, rubber, Fiberglas, or the llike, and of any suitable form or forms, such as those that will achieve the general principle, design, ind results of the invention, and which materials will :lend themselves to modern production and manufacturing methods such as molding, heating, sealing and fusing, or other processes. The tube-like nozzle 16 preferably should be made of a relatively strong, band, rigid material of fixed shape and character, resistant to deformation and deterioration. The container should be pliable and readily formable or collapsible and yet not generally expandable.
The ultimate success of the invention will be influenced by its relatively simple configuration composed of inexpensive materials coupled with modern techniques for mass manufacture and production thus enabling the resultant product to be used once and discarded. It is entirely suitable, for example, in washing one automobile or it may be used for several washings and discarded afiter the supply of concentrate is exhausted.
If prefer-red, as shown in the modified embodiment in FIGS. 5 and 6, the container 23 may have the filling opening 29, being in either case an inexpensive ride -back unit with its rider-back supply of auxiliary substance, Whether sealed in compressible collapsible Walls or otherwise. Likely uses of the invention as indicated are for the water hose attachment to include such applications as auto washing and Waxing, commercial and private window, wall, bulkhead, glass, tile, floor, deck and panel washing, or in other words, if a surface can be cleaned by Water and lliquid with auxiliary substance, it will have a likely application from the viewpoint of economy, efiiciency and ease in accomplishing the desired task.
The invention is particularly appropriate for use by an individual workman in performing the several tasks to which :the device is applicable with minimum effort, equipment and time consumption, providing the basic simple yet unique device that lends itself properly to efficient work and feasibility by the average person without the exercise of any particular skill.
It will be obvious to one skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is illustrated in the drawing and described in the specification, but only as indicated in the accompanying claims.
