An. auxi1iary .umtnzn; and.v pnoy nded int rier is secured rigidly to the lower open ends of the faucets l and I 2. This securement is efiected, at the upper ends of two laterally outwardly and then upwardly directed branch conduit portions 2| and 22, by means, in the case of each faucet. comprising a pair of

clamp rings

23 and 24 and three tie-bolts 25. Said rings are matchingly aperturedwith such apertures 120 apart, for taking said bolts; and there is interposed between each of "the faucets and the associated conduit portion 2! and 22 a gasket 26.

The inner ends of the conduit portions 2| and 9,575,368 .ilg ci 'flf J 3... 5: 1. 1

dle section 44 may be turned relative to the handle section 43, thereby to turn the rod 45 to fractionally rotate the cam entity 49 and so raise or lower the valve member 31. As the'parts are shown, the valve member 3| is fully lowered, shutting off any water discharge at the delivery faucet 29. When said valve member is fully raised, the full predetermined water pressure will be established at the faucet'29; which pressure maybe modified as desired according to how much said valve is raised or lowered.

22 meet the lower end of a vertically upstanding conduit portion 2'! and the upper end of a downwardly extending short conduit element 28 form ing the upper subdivision of a delivery faucet 29 extending forwardly as shown in Fig.2 andthen downwardly as shown in Figs. 1, 2 and 4.

The shut-off and pressure control vnv'ep'm vided includes a valve seat 30, and a cylindrical valve member 3| fixed on the lowerend of avertically 'endwisely movable rod 32. This rod extends up through the conduit portion 21' and through a screw-cap 33 for said conduit portion, for projection above said cap. At its top the rod 32 is formed to provide a ball 34. A bushing 31 is screw-threadedly secured in the cap 33; and said bushing serves to embrace the upper portion of the rod 32 to permit easy'up and down endwise movement thereof, and also acts as a journalling means for a spur gear 35 meshing with the two spur pinions l9. Said gear 35 is held in mesh with the pinions l9 by an annular flange 36 carried exteriorly at the top of the bushing 31, as the pinions l9 rise an'clfall during lifting'and lowering of the valves l5 and 15.

A single swing-arm actuator 38 is provided and includes a tube 39 fixed near its inner end in a bracket 45 secured-as at 4! to the gear 35. On the outer end of said tube is fixed, as at 42; a handle section 43. Beyond the outer face of the latter, the tube 39 extends into another handle section 44. Rotatable in the tube 39 is a rod. with its outer end pinned as at 46 to the handle section 44. The inner end of the tube 39 is re' duced in external diameter as at 41. i

The ball 34 is a cam follower relative to a cam groove 48 partially formed in each of two members of like construction except for a hub portion carried by one of them, but of" opposite hand; said'members being shaped and'coupled to provide acam entity 45 for presenting said groove. The said cam entity is rotatively mounted as shown on the reduced inner end portion 41 of the tube 39; and is fixed to the inner end of the rod 45, as by means of a cotter pin '50 sent through the rod and also through the hub portion'of that one of said members constituting the left half, as viewed in Fig. l, of the cam entity 49.

Fig. 4 illustrates a casing 5|, which may be used to enclose the entirety of the fixture, except for the handle-carrying end of the actuator '38,'and except for the delivery faucet 25. At the front of the casing is a long horizontally extending slot 52, through which said actuator projects: and along which it is movableto causerotationof the gear 35 in one direction or the other through somewhat less than 180 A portion of the bot tom wall of the casing 5| is shown in-Fig. 1, this wall having an opening 53 for protrusion of the delivery faucet as shown in Figs. 1 andl.

Operation In any angular adjustment of the actuator 38 The actuator 38 has an angular swing about the axisof .therod 32 as a center, through substantially thereby to rotate the gear 35 through substantially a half revolution in one direction or the other; said actuator being shown in Figs-l and 2 at we limit of its said swing. The

ratio of the pinions I9 to the gear 35 is one to three. Therefore, on each half revolution of the gear 35, both pinions will rotate through one and one-half revolutions, and so each of the. valve members 45 and iii-will be rotated through one and one-half revolutions.

Because of the already describedthreadedconnection l5''-l 5" between the valve 'member" 15 and-the faucet l5 and the already described threaded connection IBI5"- between the valve member 16 and the faucet it, on swinging the actuator 38 to its pcsitionshown in Fig. 1 from itsother limit of swing, that is, from its position indicated in dot and dash lines at 38 in Fig. 1, the valve member l5 will be spirally raised 'to fully open conditionand the valve member I6 willbe spirally lowered to fully'close'd condition; as shown in Fig. -1. Similarly, on'swinging the actuator 38 from its position shown in Fig. 'l' to its position indicated at 33 in that view',-'the valve member 16 will be spirally raised to fully open condition and the valve member 15 will-be spirally lowered to fully closed condition. Similarly, also,'on swinging the actuator 33 to cause the same *to extend as indicated in dot and dash lines at 38 in Fig. 2, both of the valve members I 5 and-I5 will be in half open condition, Thus, according as the actuator 38 is'swung into the selected one of a multitude of different positions, over a swing of the actuator through substantially 180, precisely-the desired mixture of-hqt and cold water may be obtained atthe faucet 29.

While we have illustrated and described the preferred embodiment of our invention, it is to be understood that we donot limit ourselves to the precise constructions herein disclosed'and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims. 7 7 q Having thus described our invention, what we claim as new, and desire-to secure by United States Letters Patent isz 1.
