UNITED'STATEs PATENT OFFICE.

OSCAR P. BENJAMIN, OB DETROIT, MICHIGAN, AssIGNoB. To CAPITOL BRASS WORKS,

BATH COCK.

Application tiled May 31,

To all whom t may concern.'

Be it known that I, OSCAR P. BENJAMIN, a citizen of the United States of America, residing at Detroit, in the county of IVayne and State of Michigan, have invented certain new and useful Improvements in Bath`- Cocks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention rela-tes to bath cocks and that class of faucets, spigots or outlet members, from which different kinds of liquids may be discharged.

The primary object of my invention is to provide a cock with a nove-l mixing chamber which affords a quick Control over the uniformity of temperature in the flow of water or other liquid from the cock.

Another object of this invention is to provide a bath cock having a chamber common to connections established with the bath cock, said chamber having a. Common outlet and detlectors or baffles therein which cause liquid from the connections to co-mmingle before being discharged from. the chamber.

further object ofmy invention is to furnish a bath Cock with the mixing chainber which will contribute to an artistic dnesign of the cock and the location of the chan'lber in no manner whatsoever interferes with, the operation of either valve of the cock.

The above and other objects are attained by a cock construct-ion which permits of desired proportions of hot and Cold water being mixed for al desired degree of tenipcrature, and the construction entering into the cock will be hereinafter described and then claimed.

Reference will now be had to the drawing, wherein- 'Figure 1 is a plan of the bath cock, partly broken away and partly in a. horizontal section;

Fig. 2 is a front elevationof the saine partly broken away and part-ly in longitudinal section, and

Fig. 3 is a central cross sectional view of the bath cock.

In the drawing, the refe-rence numeral 1 denotes aback plate with the ends thereof substantially circular in front elevation and the intermediate portion of said plate is provided with a raised o-r ver/'tical portion 2.

On the rear face of the back plate 1, Con- 1921. serial No. 473390.

centric with the'` circular ends thereof, are connections 3 communicating with openings 4l in the back plate, said connections permitting ofthe bath cock being attached to the wall of a bath tub, basin, sink, or other structure, and also to pipesl or conduits adapted to supply hot and cold water to the bath cock.

On the front face of the back plate l, at the ends thereof, are outwardly extending frusto-conical shaped valve bodies 5 and 6 comnninicating with the openings t in the back plate 1 to receive water thenefrom. The valve bodies 5 and 6 are provided with adjustable valve stems 7 and stuffing boxes 8 through which the valve stems operate, said stui'i'ing boxes being of a conventional form harmonizing with the finish of the bath cock and insuring anon-leakable connection. between the valve bodies andthe adjustable valve stems. Y 0n the outer ends of the valve stems 7 are cranks or handles 9 of a conventional'form andv on the inner ends of the adjustable valve stems 7 Vare valvular members 10 adapted to seat at the marginal `edges of the openings 4l? an"d close said openings.

The confronting or inner side walls of the valve body 5 are integral with a mixing chamber 1l which is formed by a vertical S5 enlargement or shell 12 carried by the back plate 1 and the vertical portion 2 thereof, said mixing chamber being in the form of a pocket in said wall 12 communicating with the valve bodies 5 and 6 by lateral passages 13. The enlargement or shell 12 has a shape which contributes to the general appearance of the bat-h cock and the lower end ofthe -enlar, ;'ement or shell 12 has a discharge nozzle 14 or outlet opening to which is opposed the pocket in the wall 12 and to which outlet may be Connected a nipple 15, hose coupling, or any other outlet device.

In the passages 13, between the mixing 100 chamber 11 and the valve bodies 5 and 6, are upwardly inclined ydeflectors 16 extending at an angle in the direction of the topV wall ofthe mixing chamber 11, said deflectors providing transverse partitions inte- 105 gral with the side walls and bottom walls of the passages 13 and thus reinforcing the enlargement or shell 12 at its juncture with the valve bodies 5 and 6. 1.

Assuming that the valt'es of the Jbath cock 11o are open, the1wateradmitted to the Valve bodies 5 andEv 6 will impinge against the deflectors 16 and be deflected upwardly to the top-` wall of themixing chamber where 5 the water will commingle and be deflected to the bottom of the mixing chamber and pass out of the discharge nozzle 14. It is therefore apparent that in causing the water to be discharged upwardly in two l0 opposed streams that the water thoroughly mixes vbefore reaching the discharge nozzle and consequentlyit is -possibleito maintain a desired admixture, as to temperature,

when' one-valve body is'supplied with hot 15" water and the' other-with cold water. The uniform admiXt-ure can Aalso be maintained withftother liquids for v' purposes other than a uniform temperature, and it is practically impossible for'one-liquidto flow from the Zcock without commingling with the other liquid when both valves are openv or even approximately so; Ordinary city water pressure will be sufficient to cause the water to eomniingle inthe mixing chamber and maintain an aqueous curtain or body therein be-used,=. and that the general arrangement and design ofthe structural element entering into the bath cock may be varied, without departing from the spirit of the invention` as defined by the appended claims.

IV'hat I claim is l. A cock comprising horizontally disposed Valve bodies, a mixing chamber connecting` said :valve-bodies and extending to a plane above said Valve bodies and having a depending outlet, and vdefiectors between said Valve bodies `and the 'l outlet of said mixing chamber: extending upwardly and inwardly away from said outlet and causing liquid' to commingle at a point substantially removed from said out-let and be thereafter deflected downwardly to the depending outlet of saidmixing chamber.

2. In a faucet wherein liquids-are adapted to commingle cent-rally of the faucet and dis-charge through an outlet in the bottom wall lof the faucet; 'a mixing lpocket in the upper wall of said faucetopposed to said outlet, detlectors for directing the liquid towards the top of the faucet, said deflectors extending upwardly at an inclination from the bottom wall ofthe faucet adjacent the outlet thereof with the upper ends of the deflectors closer to the axis of the faucet outlet than the lower ends of said deflectors.

In testimony whereof I aflix my signature in presence of twotwit-nesses.

@SCAR l). BENJAMIN.
