4 Claims.

This invention relates to new and useful improvements in scrubbing or washing devices, and more particularly to such devices for use in washing walls, ceilings and like surfaces in conjunction with machines of the general type shown and described, for example, in United States Patent No. 2,003,847.

The principal object of the present invention is to provide a scrubbing or washing device of the type described wherein the flow of cleaning or rinse fluid t the surface being washed may be controlled and regulated at will by the user without interrupting or interfering with the washing operation.

Another object of the invention is to provide a novel scrubbing or washing device of the character set forth which is constructed and arranged to permit quick and easy interchange of the scrubbing members thereof.

Still another object of the invention is to provide a washing device of the type described having a handle structure which is readily detachable and embodies a novel valve mechanism for controlling the flow of fluid to the scrubbing memher.

A further object of the invention is to provide a scrubbing or washing device embodying certain novel features of construction and arrangement which is comparatively inexpensive to manufacture and is highly eificient and effective in operation and use.

These and other objects of the invention, and the various features and details of its construction and operation, are hereinafter full set forth and described with reference to the accompanying drawing, in which:

Fig. 1 is a view in perspective of a wall washing machine incorporating scrubbing or washing devices made in accordance with the present invention, and illustrating the manner and use thereof;

Fig. 2 is a view in perspective of a washing device made according to the present invention and showing the major parts thereof in relatively separated relation;

Fig. 5 is an enlarged fragmentar sectional view showing the construction and arrangement of the fasteners for detachably securing the washing member to the handle or body structure of the device; and

Fig. 6 is a view in perspective showing a covering surrounding a washing device which under certain washing conditions.

Referring now more particularly to the drawing, washing apparatus of the type to which the pres-- ent invention relates may comprise aPa lL-nf tanks l and 2 adapted to contain, respectively, a mixture of water and cleaning material such as a suitable detergent and-a supply of; clear water for rinsing purposes. Pressure means-inthe-form of a hand pump 3 may be provided formaintaining the liquid in the tanks I and 2 under desired pressure, and leading from the tanks are hoses 14 and 5, respectively, having scrubbing .;or washing. devices 6 connected to their outer ends,

According to the present invention; the scrubbing or washing devices 6 each comprise a body member 1 in the form of a, rigid plate of metal, plastic or other suitable material. Secured upon the upper face of the body plate 1 is a valve '8, the body 9 of which is secured-directl to the surface of the plate I. The valve body 9 is provided at one end with an axial bore portion In of relatively large diameter, an intermediate bore portion I l f reduced diameter and a bore portion l2 at the other end of the body 9 having a diameter slightly less than the bore portion ID but greater than that of the bore portion ll.

Threaded into the bore portion {0 of the body 9 is a fitting I3 to which is connected the outer end of say the hose 4 of the washing machine. The inner end of the fitting I3 is provided with a relatively large bore portion [4 in which is seated a coil spring I5. The spring l5 acts between an annular shoulder in the fitting I3 and the outer face of the head portion "5 of a valve element I! normall to maintain the valve in closed position against the wall I 9 of the valve body 9 as shown in Fig. 4 of the drawing. The valve I1 is provided with a stem I8 which is slidably mounted in the bore portion ll of the body 9, the stem 18 being helically grooved as indicated at 29 to permit flow of fluid from the hose 4, through the bore portions l0 and l I, and thence outwardly of the valve body 9 through a discharge port 2| therein and a registering opening 22 provided in the body plate I of the device.

is .used

The other end of the valve bore portion I I from the portion 10 is closed by a resilient washer or diaphragm 23 which seats against the shoulder provided at the inner end of the bore portion l2, and this diaphragm 23 is held in fluid-tight relation against said shoulder by means of a gland or fitting 24 that is threaded in the valvebodyfl, for example, as shown in Fig. 3 of the drawing. Slidably mounted within the fitting 2 4 a plunger face of said body at one side of the plunger 25, and

at the other side of said plunger there is secured a guide pin 36 which extends through an opening 27a in the lever and has a cross-head portion 36a constituting a stop limiting the outward or' in operative position of the'leverj Inward actu ation of the plunger 25 as described displaces the diaphragm 23 in the manner shownin Fig. 3 of the drawing and causes the valve element I! to be actuated to open position to permit liquid to flow through the valve and discharge through port 2| and the opening-22 in the plate I. The

helical grooves '20 in the valve stem l8 are of relatively-small cross-sectional-area and provide substantially a'metered flow of liquid through the valve l8.

Detachably secured to thennderside .of the body 'plate' 1 'of the washing device is a scrub- -bing or washing'elem'ent generally designated '28. element 28 comprises a sponge portion "30; preferably of the synthetic or artificial type, and a backingmember-fl which is provided with an opnling 'of hole '3la therein in register with the 1ateopemng g22? '{Ihe backing member 3| preferably is' a fiexible material such as fabric, for examplefcanvas or the like, and is secured to 'the sponge-"member 30, for'example, by relatively coarse stitching 32 or a suitable adhesive.

{The scrubbing or washing element 28 comprising the sponge ;3 0'and backing 3| is detachably secured tothe-body plate I, for example, by means of snap fasteners or the like, the intercooperating portions 33a and 33b of which are secured in'the body plate 1 and backing member 3|, respectively; '-for example, as shown in Fig. '5.

Inoperation of the device, and assumin for example that the hose 4 is attached to the valve fitting 13 of the "body structure, a suitable washing element 28 is secured to the plate I by means of the snap fasteners as aforesaid, and the cleaning and rinse liquids in the tanks l and 2 of the washing'r'nachine are placed under pressure by operation of the hand pump 3. The operator then picks up the washing device which is connected to the cleaning liquid hose .by grasping the valve body 9 thereof with his 'hand' and operates the lever 21 in the direction' of the arrow in Fig. 4 to unseat the valve l1 and cause cleaning liquid to discharge through the port .2I and openings 22 and 3l a into the sponge member .30 thereby wetting it. The device is then swept back and forth or up and down with the wet sponge cleaning elen ght 30 in contact with the surface to be cleaned, and duringthe cleaning operation the rate of flow of cleaning fluid to the sponge 30 may be regulated and controlled at will in accordance with the requirements of the particular cleaning operation by manipulation of the valve lever 21. When the wall or other surface has been cleaned sufficiently, another of the washing devices B is attached to the rinse hose and the cleaned wall is rinsed by using this other cleaning device in the" manner just described. In some cases, :it has been founddesirable to enclose the devices 6 within a bag or sack 34 of terry cloth or other similar soft yet rough-surfaced material.

From the foregoing it will be observed that the present invention provides a device of the type described wherein the flow of cleaning or rinse liquid to the scrubbing member may be controlled and regulated at will by the user without interrupting or interfering with the washing operation. Also, the novel construction and arrangement of the cleaning device permits tially flat body member having an opening there-- 'through, a scrubbing and cleanin member having a substantially flat top surface, abacking overlying a portion of the top surface of the scrubbing and cleaning member and having therein an opening registering with the opening in said body member, means securing said backing and scrubbing and cleaning member together; separable fastener means having a part secured respectively to said backing and body member and detachably connecting the same together, a valve mechanism including a casing secured to the upper surface of the body member and constituting a hand grip for an operator to grasp and manipulate the washing apparatus, and a lever connected to said valve mechanism and extending laterally along one side thereof for actuation by a finger of the operators hand to control the flow of liquid through the openings in the body member and backing to said scrubbing and cleaning member.
