SHAMPOOiNG DEVICE INCLUDING FOAM GENERATING MECHANISM Filed Aug. 27, 1964 1 BATTERY POWEREB Moroa \vwem'oa D R. Nmaswamsea United States Patent 3,278,974 SHAMPOOING DEVICE INCLUDING FOAM GENERATING MECHANISM Dan R. Nighswander, Fox Point, Wis., assignor to E. R.
Wagner Manufacturing Company, Milwaukee, Wis., a
corporation of Wisconsin Filed Aug. 27, 1964, Ser. No. 392,576 15 Claims. (Cl. 15-510) This invention relates to shampooing devices for rugs, carpeting, upholstery and the like and, more particularly, to a foam generating arrangement for such a device.
shampooing devices, of suitable design, have gained recognition and acceptance for do-it-yourself household shampooing of rugs, carpeting, upholstery and the like. However, most present conventional designs rely on brush and roller action on the article being shampooed to generate the cleansing foam. In other words, the shampooing liquid is applied in liquid form to the rug or rollerbrush assembly and is then agitated by the roller-brush assembly to produce a foam. This procedure has a tendency to wet the article being shampooed and although some wetting may occur in any shampooing operation it should be kept to a minimum so as not to require an unduly long drying time and as it generally has a detrimental effect on the article being shampooed.
An object of this invention is to convert the shampooing liquid to a foam state prior to application to the article being shampooed. 1
Various foam generating constructions have been pro posed prior to this invention but such prior constructions have generally been limited to use in larger, commercialtype shampooers as opposed to the do-it-yourself household-type shampooers. This limitation on the use of such foaming constructions is due to a number of reasons one of which is their relative complexity which makes their incorporation in such do-it-yourself shampooers impractical from a cost standpoint. A further reason for this limitation has been the source of power required for the foam generators. For example, some devices require manual operation of the foam generator which is unsuited to shampooing as it interferes with a smooth and simple shampooing operation since it is difiicult to manipulate both the shampooer and the foam generator at the same time so that either one of the operations must be suspended to achieve the other. Moreover, other devices although utilizing an electrically-powered generator have required connection to an external source of power thereby destroying a number of the basic advantages of a do-it-yourself shampooer, namely that it is compact, self-contained, readily portable and manipulatable.
Accordingly, heretofore available foam generators have not lent themselves well to use in do-it-yourself shampooers as they have generally contained features which are directly contrary to the basic design considerations in household do-it-yourself shampooers which, for example, are that the shampooer be relatively low cost to put it within reach of the consuming public and that it be compact, readily portable and easily manipulated. Accordingly, another object of this invention is to provide a foam generator which is readily adaptable to such shampooers without adversely affecting its basic low cost construction, its compactness or its portability while still affording elfective foam generation and shampooing.
A more specific object of this invention is to provide a foam generator which utilizes an internal, battery source of power as opposed to an external source of electrical power.
Other objects and advantages will be pointed out in, or be apparent from, the specification and claims, as Will obvious modifications of the embodiment shown in the drawings, in which:
FIG. 1 is a section view of the lower, article engaging portion of a shampooer incorporating this invention;
FIG. 2 is a view taken generally along line 2-2 of FIG. 1;
FIG. 3 is a section view taken generally along line 3-3 of FIG. 1; and
FIG. 4 is a partial view of the hand grip portion of the shampooer handle with parts broken away to expose a portion of the control mechanism.
With particular reference to the drawings, a portion of the shampooer body is illustrated in FIG. 1 and includes shroud 10 and reservoir 12 separated by wall 14. Rollerbrush assembly 16 is of conventional construction, is supported from shroud 10 in a conventional manner (not shown) and includes rotatable roller 18 and relatively fixed brushes 20 and 22.
Reservoir 12 contains a suitable shampooing liquid and the shampooer includes foam generator 24 for converting the shampooing media from a liquid to a foam state prior to application to the article being shampooed. More particularly, the foam generator includes battery-powered motor 26 of conventional construction, for example it may comprise a suitable DC. motor powered by rechargeable nickel cadmium batteries. The batterypowered motor is supported in recess 28 formed in the front face of the body of the shampooer. Foam cup 30 is connected to the inner surface of the front face of shroud 10 and is formed by bottom wall 32 and vertical walls 34 extending from the bottom wall. Agitator head 36 is positioned within the foam cup and arranged below the upper termination of cup walls 34. Drive shaft 38 extends from motor 26 into the shroud and is connected to agitator head 36 to impart rotation to the head when motor 26 is energized. Agitator head 36 can take any one of a number of suitable forms effective for foam generation, as illustrated in the drawings (particularly FIG. 3), head 36 includes a pair of arcuate blades 36a and 36b extending generally tangentially from mixer head 36 and effective to agitate the liquid shampoo and convert it to foam.
Foam cup 30 also includes hollow tube coupling 40 extending from an opening 42 formed in bottom wall 32 of the foam cup. Coupling 40 forms a part of a conduit arrangement connected between reservoir 12 and the foam cup for delivering liquid shampoo from the reservoir to the foam cup. To complete this conduit arrangement, opening 44 is provided in wall 14 and hollow tube coupling 46 extends from opening 44 with a length of flexible conduit 48 being engaged between couplings 40 and 46.
The foam cup is arranged vertically below reservoir 12 so that liquid from the reservoir flows naturally to and rises in the foam cup without the need for any auxiliary members. With liquid delivered to the foam cup, motor 26 can be energized to rotate agitator head 36 and convert the liquid to foam as it rises in the foam cup. The foam cup is preferably positioned over at least a portion of roller 18 so that the generated foam spills over the upper end of the foam cup onto the roller rather than directly onto the article being shampooed. Delivering the shampooing media in a foam state substantially reduces the amount of undesirable wetting of the article being shampooed and, moreover, by positioning the foam cup over the roller the undesirable Wetting is further reduced since even in a foam state the shampooing media is not applied directly to the article being shampooed.
In operation foam is required only periodically during a shampooing operation so that a continuous supply of foam is not needed. This invention contemplates providing the shampooer with a control to afford the operator selective control over foam supply. More particularly, valve 50 is supported at opening 44 to selectively open and close the passage between the reservoir and the foam cup. Structurally, valve 50 is in the form of a truncated cone and opening 44 is provided with an angular surface 51 which serves as a seat for valve '50. Valve 50 is supported on valve stem 52 and is biased toward a closed position by coil spring 54 which is seated between valve 50 and bracket 56. Bracket 56 can take any suitable form as long as it does not unduly interfere with liquid flow to opening 44. As illustrated bracket 56 is generally U-shaped and its legs 57 are provided with openings 58 to achieve optimum flow of 'the shampoo liquid from the reservoir through opening 44 into the conduit passage.
Actual control over opening and closing of valve 50 is provided by actuator 60 slidably supported on handle 62 adjacent grip portion 64 of the handle. The handle is suitably connected to the reservoir, for example, extending into the reservoir and being fixedly attached to bracket 56. Valve stem 52 extends through the handle to slot 66 adjacent grip portion 64 and includes -a turned end 68 extending through the slot and engaged in a notch 70 in actuator 60. Spring 54, in addition to biasing valve 50 in opening 44, biases end 68 into engagement with notch 70 and holds actuator 60 in the position illustrated in FIG. 4. The valve is opened to permit flow of shampooing liquid to the foam cup by moving actuator '60 upwardly toward hand grip portion 64 and, when the actuator is released, spring 54 returns the valve to its closed position.
Motor 26 can be suitably energized through any desired control arrangement to agitate the shampooing liquid as it enters the cup. Since motor energization is required only when shampooing liquid is present in the foam cup it is preferable that the motor be energized only at that time and this invention contemplates a control for the motor which energizes and de-energizes the motor simultaneously with opening and closing of valve 50, respectively. More particularly, leads 72 and 76 extend from motor 26 (motor connections being conventional and not shown) to snap switch 78 mounted on handle 62 adjacent actuator 60 by screws and bracket assembly 79. Switch 78 is of the normally closed type and with actuator 60 in the position illustrated in FIG. 4 button 78a of the switch is depressed and the electrical circuit of the motor and battery source is open. Movement of actuator 60 toward grip portion 64 to open valve 59 also releases switch button 78a actuating the switch and completing a motor circuit to thereby agitate the liquid which is being delivered to the foam cup with the valve being open. This arrangement has the particular advantage of energizing the motor only when liquid is being delivered to the foam cup thereby synchronizing motor energization with the supply of liquid. Moreover, the particular valve control arrangement affords the operator precise control over the amount of liquid furnished so that the liquid can be supplied in limited measured amounts as required and to insure proper conversion of all liquid to foam so that the shampooing media is delivered only in a foam state and that being a light, not highly saturated foam.
This invention provides a shampooer which is compact and completely self-contained. The shampooer requires no external power source, it is readily manipulated by the operator with only one hand so that shampooing can be accomplished in a smooth and continuous operation, and the foam generating arrangement insures effective conversion of liquid to foam and minimum wetting of the article being shampooed.
Although but one embodiment of the present invention has been illustrated and described, it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention or from the scope of the appended claims.
