This invention is a water faucet of the kind commonly designated as combination faucets adapted to be operated by a single handle for the delivery of either hot, cold or warm wa- 5 ter through the one common nozzle.

' I The principal object of the invention is to Providev a relatively simple, durable and cheap structure of the kind indicated.

IAnother object is to provide an assembly 1 of ,an outer casing with beveled inner walls,

hot 'andcold water ports leading thereinto, and having a beveled core rotatably seated Within the said casing with a semi-circumferential water passage or port cut through the 15 wall upon one side and adaptedto connect the two said water ports upon the appropriate lateral movement of the said core, the beveled: coacting faces of theccasing and core servingto compensate for wear.

A further object is to. provide a structure as indicated, having a central valve towcontrol the flowof water through the device, the said valve being adapted for vertical movement for opening and closing the water channels,

and being sealed against water leakage by awasher having a V-shaped inner margin adapted to spread inseveral directions under water pressure.

' Another object is to provide means in the said core upon the side opposite to the said semi-circumferential water passage for ofi'- setting the water pressure against the core due to .water flowing intosaid passage.

Another object .is to provide means for holding the said core to its seat-against the upward tendency resulting from water pressure.

With the foregoing and other objects in 6 view, attention is called to the following specification and vthe accompanying drawings constituting a part thereof, and wherein Figurelis a vertical section through the casing and interior assembled elements; 45 Figure 2 is a horizontal section on the line 2-2 of Figure 1;

Figure 3 is a vertical section on the line 33 of Figure 1;

Figure 4; is an enlarged sectional detail of 50 the central valve;

Figure is an enlarged detail view of the I 7 core.

This invention comprises an outer circular casing 1, having its inner wall faces or periphery beveled or tapered inwardly from top to bottom or from one end to the other as shown at 2 and having the diametrically opposite hot and cold water ports 3 and 4; connected with the water leads 5 and 6. A lower nozzle plate 7 having the integrally formed nozzle 8 is Y mounted at the lower side of the casing 1 by means of set screws 9 passed through the upstanding flange 10. The flange 10 is relatively thin so as to provide an .annular shoulder 11 at the bottom of the casing for a purpose later to be referred to. A hollow core 12 is rotatably seated within the casing 1, the inner face or periphery thereof being cylindrical or straight as shown at 13, and the outer face or periphery being conical or bevelled or tapered as shown at 14, complementarily of the beveled inner faces 2 of the casing. This core is formed with an upper lip 15 adapted to outwardly overlap the upper edge of the casing 1, with a straight lower flange 16 depending into the nozzle plate 7, thus leaving the spring recess 17 between the flanges'16 and 10. The core 12 is formed with a semi-circumferential water channel or port 18 cutthrough one side sufliciently to partially span the two ports 3 and 4 as shown in Figure 2, and with a pressure balancing recess 19 cut semi-circumferentially upon the opposite side. An annular valve seat 20 extends inwardly around the lower wall of the core 12, the same being recessed upon its upper side to receive a packing washer 21. A handle rest 22, having an upstanding lug 23, extends laterally from one side of the core 12.

A central valve 24 is seated upon the valve seat 20 of the core 12 upon the washer 21. This valve is provided with a lower web 25 adapted to fully close the opening 26 through the center of the core 12, and a spaced upper web 27 which is recessed upon its periphery as shown at 28 for the reception of the washer 29 which is nicely fitted 'thereinto. The washer 29 is provided with a V-shaped groove upon its inner periphery as shown at for a purpose which will be later explained.

I l l l 1 Water ducts 31 open from the recess 28 downwardly. A valve stem 32 extends upwardly from the valve 24 above the top of the casing 1. A coil spring 33 is seated over the stem 32 and bears upon the valve 24. A core cover 34 having a central aperture 35 for thepassing of the stem 32, is fastened atop v the core 12 and spring 33 by screws 36. Thus the spring 33 normally closes the valve 24 to its seat. Another and larger coil spring 37 is seated within the spring're'cess 17 andhas its againsttheshoulder 11 of the casing 1. Thus the action of the spring 37 is to normally hold the core 12'downwardly to its seat, andfcounteracts the tendency of the water pressure to force the said core upward. The water entering and flowing through the device exerts a pressure alsowithin the recess 28' of the web 27 which results in the straining of the washer 28 diametrically to seal it against the inner face of the core 12 andfalso in flexing the inner feather edges of the inner periphery of the. washer outwardly to seal it against the possibility of water working past the sides ,of-the washer. Ahandle 39 has an end pivoted at 40 to the upper end of the valve stem 32,;and a slot 41 is cut in the lower side of the handle; for engagement with the flat lug .23

of 'the'handle rest 22. A sliding latch 42 uponthe handle serves to hold the handle locked horizontally upon the-rest 22 from which position it may be released by a' simple manipulation of the-latch. The latch here shown generally is the subject of a co-pending application, so it is not particularly described here and is not here claimed as part of this invention.

It is thought that the use and operation of the faucet-will befully understood from the foregoingdescription. With the handle in the-horizontal position shown. in :Figure 1, i

the valve 24 is closed to its seat and no water can fio'w. through. Upon releasing and'depressing thehandl'e, the valve 24 is raised, thereby admitting water from the ports 3 and 4 into the channel 18 of the core 12 whence it flows down through the core and out through the nozzle simultaneously inoving the handle to one side or the other, the c ore 12 is rotated through the engagement of thehandle with the rest 22 and thus either of the said ports may be entirely or partially closed by the core 12, whereby the temperature ofthe water may be easily regulated.

Water" under pressure also flows into the recess .19, whereby the water pressure is sub- .Stantially balanced upon all sides of thecore 12 and reduces friction and-facilitates operation' of the valve. The beveled formation of the casing and core provides a perfect watertight joint and provides for the wear of the mating surfaces.

While I have herein described a certain I specific manner and method of constructing and assembling the elements of my invention,

it is understood that I may vary from the 7 same in minor details, not departing from the spirit ofmy invention, soas best to construct a practical device for the purpose intended, as defined in the appended claims.

I c1aim;: w lower end braced against a ring 38 secured to thelower face of the flange 16 of the core 12 and projecting. therefrom .as shown. The upper end of the spring 37 is braced the said core having a semi-circumferential water channel cut through'one side for partially spanning the said'water ports of the casing, and an oflsetting pressure balancing recess in the other side,'and having an upper lip adapted to outwardly overlap theupper edge of the casing, a coil spring mounted around the lower end of the corewithin the said spring recess of the casing and braced between the core and the casing for holding the core to its seatwithin the casing, a valve seated within the core to control the flow of water therethrough, the-said valve 1 having a lower web for closing thewater channel and a spaced upper web recessed peripherally for the washer, thesaid recess opening downwardly through water ducts in the said recess, the same being formed. with a V-shaped groove upon its inner periphery at the mouths of the said water ducts,

a closure for the open top of the core, means for holding the said valve to .its seat, means 1' for rotating the said core and means for raising and lowering the said valve..

2. In a' device of the kind described, a casing having two spaced inlet ports and a nozzle opening at its-lower side, the said casing 11 having its'inner wallface tapered from the intended top end to the intended bottom end, a complemental hollow core rotatably seated withinthe casing and having a water channel cut away at one side for partially spanl ning the said inlet ports, a valve seatedwithin thesaidcore for controlling the flowof watertherethrough to the said nozzle opening, resilient means in the lower part of the casing for holding the said hollow core to its seat within the casing, and resilient means for holding the-said valve toits seat within the said hollow core.
