the like and particularly to a valve for use where both hot and cold water connections are available.
\ One object of theinvention resides in the Yd hot or cold water may be provision of a device whereby cold and hot water may be admitted'to a mixing chamber in the proportions required to provide water of the desired temperature, or whereby either discharged independently of the other. I
Another object is to provide means where by hot or cold water, or water of medium temperature may be secured by use of but one valve or faucet. Y
A further object is to design a very simple, substantial and economical mixing valve for use in hotels, homesand in fact anywhere that it is desired to provide water at different temperatures at the pleasure of the user.
A still further object is to provide a mixing chamber having hot and cold water inlets and also provide unitary controlling means for regulating the water admitted to the mixing chamber and controlling the discharge of the mixed water after the mixing has been effected.
The above and other objects will appear as the specification progresses, reference being had to the accompanying drawings, in which like reference numerals indicate like parts throughout the several views thereof.
In the drawings:
Fig. 1 is a side view of my improved valve.
Fig. 2 is also apart section fragmentary side view thereof.
Fig. 3 is an end view taken on the line 3--3 of Fig. 2.
Fig. 4 is a detail side view of the mixing chamber and nipple connection.
Fig. 5 is a front view thereof.
Fig. 6 is: also a front view of the valve, showing in full lines the position of the valve when discharging water of medium temperature, the dotted lines illustrating the positions when discharging hot or cold water.
In hotels and public buildings where both hot and cold water connections are available, it is customary to provide two valves, the water discharging intoa basin, the valves 717,022,.fi1ed May 31, 1924. Application for reissue Serial No. 296,023. i
being regulated so that the water of the desired temperature is provided.
For sanitary reasons when shaving, washing, etc.,it is desirable to take water directly from the faucet, and before it discharges into the basin, and where the hot and'cold water discharge from individual faucets, this is not possible as the water is either too hot or too cold, and I have therefore designed a combined sanitary valve and mixing chamber, by means ofwhich water of any desired suitable temperature can be secured, by merely rotating the valve slightly in one direction or the other.
Referring now particularly to the drawings in which I have shown the preferred embodiment of my invention, thenumeral 1 indicates a mixing chamber having openings 2 and 3 on opposite sides thereof, both of which are internally threaded to receive pipes 4 and 5 respectively which connect with the hot and cold'wate'r reservoirs respectively, said openings terminating in elongated slotted'openings 6 communicating with the centrally disposed passage 7 formed in' the mixing chamber. r
In thepresent illustration the device is shown in connection with an ordinary household sink, the back of which is indicated by the numeral 8, and against which the mixing chamber is placed.
i A pipe nipple 9 extends through asuitable opening in the back of the sink and is threaded into the centrally disposed passage 7 ofthe mixing chamber, a shoulder 9 being provided intermediate the length of this nipple 9 and a washer 10 is mounted thereon and is held tightly in position against the sink'by means of a-nut 11 as shown, the end of this nipple 9. being externally threaded and formed with spaced apart projecting shoulder portions 12 for a purpose to be presently described. I
A sleeve member 13 is brazed to a conven tional faucet 14, and this canbe of any pre ferred type, either self-closing or hand manipulated, the sleeve 13 extending through the nipple 9 and into the mixingchamber, and being formed with spaced apart elongated slots 15 adapted when the valveis in up-.

washer 10 having suitable indicia thereon to 7 indicate when the valve is turned to position to discharge hot, cold, or warm water.
The slots in thesleeve 13 are "of course somewhat wider than the openings 6 and are so spaced that when the handle of the valve" is in vertical position both hot and cold water in equal proportions is admitted to the passage 7, but when the'handleis swung or rotated, oneslot remainsopen while the oppo-- site slot, which admits water from the opposite supply pipe is being. closed an'd vice versa, the discharge of this mixed water being controlled by thexvalve in the faucet.
