Gam slots are formed in eachfof the blocks41 and 43, the block 41 being provided with acam slot '45 which is substantially arcuate in shape,

while the block 43 is provided with a cam slot 46 which has a substantially vertlcal I straight section 47, an upper arcuatesection 48, and a lower arcuate section 49, the sections 48 and 49 being turned in opposite directions. A collar 50 is secured to the rod 14 by a pin 51,- and said collar is providedwith diametrically opposite outstanding flanges 52. A laterally extending pin 58 issecured tothe end of one of the flanges 52 so as toiengage-the cam-slot 45, and a e laterally extending pin 54 is secured to' the end of the other flange 52 so a .to engage the f cam slot46. The'pins 53 and 54 serve to move the camblocks 41 and43 about their,

An inlet port-55 18 provided in the wall of the chamber 10 adjacentthe cam block' 41 and aninlet port 56 is formed in the/wall of said chamber 10 diametrically opposite the port 55 and adjacent the cam block 43.-

Each of the ports 55 and 56 has a threaded portiong57 to whichis secured water pipes 58 and 59 which'may be curved, straight, or provided with unions 6O connecting said pipe to service pipes 61 passing through 'the floor 62. 'Thepipe 58 may supply cold water and-the pipe 59 hot water or vice versa. A valve stem 63 is pivoted at one end to the lower end of the-block-41 by means of vpin 64, and 'a valve stem 65 is" pivoted to the lower end ofthe cam'block gage a valve seat 70. formed in each ofthe ports 55 and 56when the valves'are in a closed position. The washers are preferably made of a soft material such as rubber.

; and are held; in place, by a semi-spherical metal washer 71 secured in place by a nut 7 2; The contact surface 73' of eachof thewashv ers 69 and 69 with the' valve seats 70 is preferably semi-spherical in shape. so that asthevalve washers become worn, they may be adjusted by tightening the nuts 7 2 so that the surfaces 73 are flattened out and approach" their respective valve seats more '9 gaged from the teeth 24, the rod 14 will be closely. .An outlet" ort 74 is provided in V the chamber 10 to a low the escape of, the mlxed water at the temperature desiredm -In operation when the pawl 30 is disenmo e @Xi b t rr s 3 t its pper:

most position in which both of the valve washers 69 and 69,, will be seated ontheir respective valve seats so that no water will flow into the chamber 10 through the pipes 58 and 59. As the rod 14 is slowly moved downwardly by depressing the pedal 28, the

pin 54 will first loosen but'not" unseat the valve Washer 69,, while the pin 53 will unseat the valve washer 69 due tothe sharp curvature of the cam slot 45. 7 As the downwardly motion of the rod 14 is continued, the pin 54 willtravel in the straight section 47 of the cam slot 46, while the valve washer69. is

fully opened, and upon further downward f movement of'the rod 14, the valve washer 69 will slowly close while the valve washer 69, will slowlyopen and at the lowest point of the rod, the washer 69 will be closed while thewasher 69 'wil1 be open. Thus a thorough mixing of ,hot and cold water from the pipes 58 and 59 occur in the chamber 10 and the mixed Water of the desired temperature will flow out of the pipe 73. This faucet is especially useful for dentistsand'others' who, while working with their hands may desire to control the flow and temperature ofthe water without the necessity of interrupting the work in hand.

I would "statein conclusion that while the illustrated example constitutes a practical embodimentof-my invention, I do notlimit myself strictly to the mechanical details vherein illustrated, since manifestly the'same can be considerably varied without departure from the spirit of the invention as defined in the appended claims. Having thus described my' invention, I claim as new'and desire to secureby Letters Patent:

1. A faucet'for mixing liquids-which comprises a mixing chamber, a plurality of.

valves disposed in "said chamber and'controlling the admission of liquid to and exhaust from I the chamber, a "plurality of pivoted plates, a connection between each pivoted plate and a valve, a sliding actuating control rod, a collar on said rod having projecting lugs, a pin on the. end ofea'ch lug, each of said plates'having 'a curved cam slot-adapted to receive one of said'pins whereby the'm'ove ment of the rod will actuate the plates to operate the valve, and a stud projecting from the bottom of thecasing'in-line with the V control'rod, said rod having abore adapted to receive said stud wherebythe movement of the control rod is reinforced and id d by said'stud. j i
