4 (Ilaims. (Cl. 299-84) i to be able to regulate both the pressure and the This invention relates generally to washing devices and has particular reference to devices of that character which are adapted for use in washing dishes or for similar purposes.

A principal object of the invention is topro-- vide a device of the kind mentioned which is simple and sturdy in construction and which can be used to wash with soap and then rinse the dishes or other. articles. It is so constructed that the amount of soap, or, rather; the proportion of soap in the water, may be varied by manipulating a pair of valves according to the effect desired.

Another object is to provide a construction comprising a novel brush which will permit scrubbing the. article to be washed and while supplying either clear water or water containing the desired proportion of soap, thereby facilitating the removal of material which may be adhering too tightly to be quickly removed by the water only.

With the foregoing and incidental objects in view, the invention consists in a novel combination and relation of parts, the novel features of which are pointed out in the appended claims, and a preferred embodiment of which is hereinafter described with reference to the drawing accompanying and forming a part of this specification.

In said drawing: Fig. 1 is a longitudinal section through the de- 4 vice.

33 the construction and relative positions or other parts. 7

Fig. 4 is a partial top view of the device andshows particularly the relative arrangement of and the captions on the valve buttons- 6-6 respectively in Fig. 2. l I

The form of the device illustrated in the drawing is adapted to be attached to the hot water faucet of a water supply and used for washing 45 and rinsing dishes, although it may obviously be used for other purposes.

It may, of course, be attached to a faucet common to a hot water and a cold water supply so thatthe temperature and pressure may both be regulated by the faucet 50 valves.

The connection is made by means of a hose l0 provided with some means, such as a friction cup H, for attachment to a faucet.

Where separate faucets for hot and cold water are used, the hose may be branched with a sep- 55 arate connection H for each faucet if it is desired Figs. 5 and 6 are sections on the lines 5-5 and temperature.

The hose passes through a handle l2 integral with a removable cap 13 which may be held in place by means such as screws N on the main shell l5 of the device. The handle I2 preferably is curved so as to afford a convenient grip for holding the device and directing it in use.

' The hose is attached at Hi to a water conduit H which is so constructed as to provide branches l8 and I9 extending through a wall 22. This wall is part of a unit which also comprises walls 23, 2e and-25 which collectively form four compartments 26, 21, 28 and 29. Integral with or attached to the wall 23 is a sleeve 30 which is constructed at its outer end to form a flange 3| fitting closely within the main shell 15.. The dance 3! is to support the sleeve against lateral movement with reference to the shell l5.

Opening from the compartment 28 is a passageway 32 through the wall 23., This opening is to permit water to flow through a soap chamber to what is, for convenience, usuallyreferred to herein as a spray head. This spray head is designated 33 in the drawing. It is screwed on the outer end of a sleeve 35 which fits closely within the sleeve 30 previously mentioned. Loosely mounted within the sleeve 35 is a soap cage 35 which is preferably made of wire mesh or material which is suitably perforated to allow a soap solution to flow readily and still retain a supply of soap until it is dissolved. Mounted upon the cage is a pin 36 or other suitable projection which will permit withdrawing the soap cage for refilling after the spray head 33 is removed.

The branch is of the water supply extends through the wall 22 and into the compartment 21. The wall 23 is constructed to receive one end of a tube 31 forming an outlet from the chamber 29 and supported in a notch in the flange 3|. At its outer end the tube is bent inform a circular ring 38 around the spray head 33. The end 39 of the tube is, of course, closed so that water will be forced through perforations in the spray ring 38. It is obvious, of course, that the spray ring 38 may be a continuous one and connected in any suitable way to an open end of the tube 35, but the construction shown in the drawing has certain obvious advantages in the way of manufacture.

The flow of the water through the branch I! or the branch i9, or both, is controlled by a couple of valves in the cross-wall 25. These valves are normally held by springs 39 and 40 in closed position, as shown inFig. 6, but when the 2 valves are depressed against their springs .the

, valves are unseated, and allow water to flow through the compartments 26 and 21 into compartments 28 and 29 opening respectively into' to make the brush detachable because it will not 15 always be needed, but when it is needed to remove matter which can not be readily removed.

by the soapy water there is no difllculty in putting it in position;

In using the device it is connected to the water supply and the soap cage 35 is filled with soap in powdered or other readily soluble form. The water is then turned on and the valve, l6 depressed to allow the water to flow through the soap chamber and dissolve the. soap. 1.. This soapy watenisthensprayed upon the dishes or other workiwith a forcedep ending upon the --water pressure, which usually- ..is. su fflciena'sato wash dishes or do s milar work. However,*'i'f it 'is needed, the brush it may be put in place and used, to facilitate the washing.

After the soapy water has served its p rp se the valve'lfi is released and "the valve 45 depressed, thereby opening a passageway from the water supply to the spray ring 38 and this spray used for rinsing the dishes.

It is obvious, of course, that the valves ma be" depressed together if desired, or manipulated so as to vary the proportion of soap in the water delivered from the spray head 33 and spray ring 38. Any operation or manipulation of the valves is made convenient by so placing the valve buttons 45 and 46 that they can be reached by the fingers of the hand on the handle l2.

While the construction shown and described is quite satisfactory in'attaining the objects desired, that construction is illustrative only. The

1. A device of the character described com-' prising; a connection to a. source of water supply; a conduit communicating at one endv with said connection constructed to receive a soap spray ring disposed circumferentially of the aforesaid removable spray head and a valve in each conduit operable to open. the conduit to permit the passage of water through theconduit associated with the operated valve.

'2. A device of the character described comprising a removable spray head provided with a plurality of perforations, a spray ring separate from and curved around the spray head, devices forming independent passages connecting said head and said spray ring to a common source of water supply, the passage to the spray head being constructed to form a soap holding chamber which is rendered accessible for supplying soap by removal of. the spray head, a removable soap holding cage in said chamber and a valve in each passage, said valvesbeing operable singly or together to open either or both of said passages to the source of water supply.
