WITNESSES A TTORNE Y 8 v device for which application was filedby ne fin i fivnx nve mncnn Be it known that I, wamwneisa, ajeitizen of the United States, and a'resideflnt of the city of New York, borough of Ma'nhat tan, 1n the county and State otNew York, have invented a newand Improved Mixing Faucet, of which the following {is a full, 1 clear, and exact description. I I s liquid mixing This invention relates to means, and has reference more' particularly to means for mixing hot and cold water, said means being controlled byfa hand ,lever' so that the water issues from the iaueetfatthede 1 sired temperature. This application ,further relates to and is an improvement. over the June 19, 1919', serial Number eoezcmnd is also an improvement over the device shown in application filed October 25, 1919; Serial Number-333151. l 1

An object of. this inventi i is ol'provide a hand controlled mixingfaueetlinkwhich the flow and temperatureloyf the. water 'i'ssu? e! c miat y 9 .5 7 i i similarly-suspended between the otheripairf c from the faucet can. trolled by a lever. H y I 4 v i i 1 Another object of this invention is toprovide a mixing faucet which canioejeasily di's assembled so that repairs'can' be made."

A further object lofthis inventionzfisto provide a mixing faucet which haslval ves of resilientmaterial, said' valvjes being provided with means for adjustment when necessary due "to wear.

A still further object of this invention is to provide a mixing faucet which is espe: cially adapted for useon sinks, shower baths,

and the like.

The stuflinghoxv 13Islidaloly engages a" control rod 14 sothatsaid rod is positioned coaxial-j with i the chamber 10; 1 An annular shoulder 15 is provided on thfe {rod 14 which a is adapted to engage an annular recess in the f {cap 312 so that axial movementof'the rod 145 is prevented. 1A lever 16 :is secured tokthe upper, end of thendie loy means ofhpin 17 so that said rod may be rotated by said lever.

pivots when 'thecollar 28 is moved vertically provided in .thegwall of the chamber 10 ad-v is formed the cam block 21. Each of the ports 33 and 34has a threaded section 35 to which is secured

water pipes

36 and 37 which may be curved, straight, or provided with unions 38 connecting said pipes to service, pipes 39, passing through the wall 40 of the sink, the axis of said service pipes 39 being preferably at right angles to the axis of the pipe '11 so that the water or other liquid is di rected downwardly. The pipe 37 may supply cold water and the pipe 36 hot'water,-or

vice versa. 7 I

A valve stem 41 is pivoted at one end to the lower end of the block 19 by means of a pin 42, and a valve stem 43 is pivoted to the lower end of the cam block 21 by a pm 44. Each of the valve stems 41 and 43 is pro- I vided with a threadedsection 45 which forms shoulders 46 with-thevalve stems 41 and 43. Frusto-conical resilient valve '

washers

47 and 48 are mounted coaxially on sections 45, the smaller ends of said washer being adapted to-engage valve seats 50 formed on-each of the ports 33 and 34 when the valve is in aclosed position. Each of the

Washers

47 and 48 is preferably madeof a soft material such as rubber and is held in place by a semi-spherical metal washer 51 held in place by a nut 52. r The contact surface 53 of each of the

washers

47 and 48 with the valve seats 50 is preferably semi-spherical in shape 7 so that as the valve'washers become worn they'maybe'adjusted by tightening nuts 52 so that the surfaces 53 are flattened out and approach theirrespective valve seats more closely. a

In the modification shown in Figure 5, the

outlet pipe '11,, may be formed" on the wall of the chamber 10 and may be connected to a pipe 54 which leads to ya 'showerbath or any other desired device.

Inoperation, when the lever 16 isin thev extreme position shown in Figure 4, the pins 31 and 32 will engage the cam slots 23 and 24 so that the cam blocks19 and 21, pull the valve washers tightly against the valve seats 50 so that no *water flows into the mixing chamber 10 through the pipes 36 and 37., As the lever 16 is slowly rotated in a clock Wise direction, the collar 28 moves downwardly, thus causing the pin 32 to loosen but not unseat the valve Washer 48 while the pin 31 opens the valve 47. 'At the position shown in Figure 1, valve 47 is fully opened and the valve 48 is still closed, and upon a continued clock wise rotation of the lever; 16, the valve '47 will slowly close while the valve 48 opens until the proper'temperature and flow of water from the pipell is obtained. Thus a thorough mixing of hot'and cold water from the

pipes

36 and 37 is obtained in the I would state in conclusion that while the illustrated example constitutes .a practical embodlment of my invention, I do not'limit myself strictly to the mechanical details herein illustrated, since manifestly the same can beconsiderably varied without departure from the spirit of the invention asdefined in the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: T
