JOSEPH W. HALLER, OF HARRISON, NEW JERSEY.

COMBINATION-FAUCET 0R MIXING-VALVE.

To all whom it may concern:

Be it known that I, JOSEPH W. HALLER, a citizen of the United States, residing at lilarrison, in the county of Hudson and State-of New Jersey, have invented certain new and useful Improvements in Combination l aucets or Mixing-Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had tothe accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

The present invention has reference, generally, to improvements in that class of valves, known as combination faucets; and, the invention relates, more particularly, to a noval form of combination faucet comprising a suitable. casing and a. spindle, adapted to be turned in either a forward direction from right to left, or in a rearward direction from right to left,.for the purpose of'operating singly or separately a *plurality of valves having hot and cold -water-connections, and by means of the same spindle simultaneously operating both valves, all with a VleW of providlng a combination faucet having a single operating handle by means of which either of the valves may be operated singly, or both valves may be operated simultaneously, for.

delivery, at will, of either hot or cold water,

or a graduated mixture of hot and cold water, according to the desires of the operator.

The invention has for its further object to provide a combination valve or faucet of the general character hereinafter more particularly set forth, which shall be a most simple and eflicient construction, and, in which the arrangement'of the parts is such that the valve-disks and washers can be readily renewed in case of wear.

Other objects of the present invention not I at this time more particularly enumerated will be clearly understood from the following detailed description of the present in-- vention. i

hth the various ob ects of the presentinventio-n nvlew, the said invention consists', primarily, in the novel combination faucet or mixing valve hereinafterset forth; and, the invention consists, fu-rther- Specification of Letters Patent.

Patented July 22, 1913.

bin-ations of the various devices and parts, as well as in the details of the construction of the same, all of which will be more fully described in the following specification and then finally embodied in the clauses of the claim which are appended and which form an essential part of the said specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure l isa View partly in front elevation and partly in longitudinal vertical sec-- tion of a combination faucet or valve, showing' one embodiment of the .)rinciples of the present invention; and Fig. 2 is a top view of the same, with a horizontal sectional representation of the central portion of the valve-casing and of the cam-shaped portion of the operating handle or spindle of the combination faucet. Fig. 3 is an end view of the combination faucet or valve; and Fig. 4 is a transverse vertical section of the valve-casing and one of the valve stems, said section being taken on line 4 in said Fig. 1, looking in the direction of the arrow an Fig. 5 is a part front elevation and -a part longitudinal vertical section of a combination faucet or valve of a slightly modified construction, but still embodying the principles of the present invention; andFig. (S is a horizontal sectional representation of the same, said section being taken on line 6-6 in said Fig.- 5, looking in the direction of the arrow 1 Fig. 7 is a top view of the cover and operating handle employed with the construction represented in said Figs. 5 and 6.. removed from the valvecasing; and Fig. Sis a detail horizontal sectional representation of the carn shaped portion of the valvc-opcr ating spindle.

Similar characters of reference are em ployed in all of the said above described figures,'to indicate corresponding parts.

Referring now to thesaid drawings, the reference-character 1 indicates a suitable shell or casing, preferably cylindrical in form and horizontally positioned with its respective and screw-threaded end-members '2, which are preferably internally screwthreaded "and are closed by means of removaloly disposedscrew-plugs, as 3. Extending laterally and rearwardly from the sides of,

the end-members 2 of the said'shell creasing'l are suitably formed inlet-ports, as t more, in the novel arrangements and comand 5, respectively, for the attachment of the said shell or casing 1, in any suitable manner, to the hot and cold water pipes, respectively, as will be clearly evident. Extending upwardly from the central or middle part of the said shell or casing 1 is a tubular member, as 6 which is externally screw-threaded, as at 7, for the reception thereon of a perforated and spindle-receiving nut 8, as clearly illustrated in Figs. 1 and 3 of the drawings. The said tubular member 6 forms, with the inner chambered central portion of theshell or casing 1, a spindle-receiving chamber 9, said chamber 9 being separated from the valve-receiving chambers 10 in the respective end-portions or members 2 of the shell or casing 1 by an arrangement of two partitions, 11, each partition being provided with a valve-stem receiving bearing-portion 12, and an opening,

as 13, said openings establishing communiseat upon which rests and is rotatably arranged an enlarged seating member or element,ras 18, with which the said spindle 15 is provided, said seating member or element 18 being preferably formed with the tapering surface-portion 19, u on which is arranged a suitable packingabric 20. Mounted upon the spindle 15, above the said packing-fabric 20, is a suitable metallic packing ring'21, the parts all being arranged so'that a water-tight joint will be the result, when the nut 8 is screwed down tightly upon the screw-threaded portion of the tubular member 6 and against the said packing ring 21, as will be clearly evident. Upon the spindle, beneath the said seating member or element 18, is a valve-stem actuating element- 22, made in the form of a cam-member of the general configuration shown more particularly in Figs. 2 and 8 of the drawings, the said cam-member having the larger arc-shaped and convex surface-portion 23, contiguous and adjacent to which are two smaller arc-shaped and convex surface- portions 24 and 25. -Extending from the concave surface-portions 26 and 27 contiguous and adjacent to the respective convex surface- portions 24 and 25, are a pair of laterallyprojecting and straight or flat surfaceportions 28 and 29, connected by an areshaped and convex connecting surface 30. I have particularly in the above set forth the as will be clearly evident.

Slidably arranged in the previously-mentioned hearing or guiding portions 12 with which the partitions 11 are provided, are valve-stems 31, each valve-stem having a suitable point end-portion, as 32, extending into the chamber 9 and adapted to be' engaged by the said valve-stem actuating element or cam-member 22, as will hereinafter more fully appear. The opposite end-portions of the said valve-stems 31 project into the respective valve-chambers 10, being provided with suitably formed valve-disks 33,

adapted to be normally seated upon suitable valve-seats, as 34, by the action of suitable coil-springs 35 which are arranged between said valve-disks and the closing plugs 3 in the respective open ends of the end-members 2 of the shell or casing, and are always under compression between the said valve-disks and the said plugs.

Referring now to Figs. 5, 6, and 7 of the drawings, it will be seen, that the main central portion of the shell or body 1 is formed with a slightly upwardly project-ing part 37, formed with an annular oft-set 38, for the reception of a suitable cap, as 39, which is detachably secured upon the said upwardly projecting part 37 preferablyby means of screws 40, substantially in the manner illustrated in said Fig. 5 of the drawings. In this modified construction the spindle 15 is made upon its upper end with a reduced portion, as 41, a portion of which is rotatably mounted in a hole.42 with which the cap 39 is provided, said hole 42 forming a suitable bearing-portion for the said spindle, The spindle in all other respects is the same as the spindle shown and described in connection with Figs. 1, 2 and '3 of the drawings. However, to maintain the packing-fabric in its properly mounted position upon the said spindle- 15, a sleeve or nut-like member 43 is mounted upon said spindle, said sleeve or nut-like member being externally screw-threaded, as

at 44, and being screwed into an internally screw threaded receiving portion 45, as

clearly shown and forthe purposes, which will be evident from an ins ection of said Fig. 5 of the drawings. Suitably mounted upon the reduced portion 41- of the spindle 15 is a gear-wheel 36, andinmesh with said gear-wheel 36. is a pinion 46 suitably mounted upon anoperating stem or spindle 47 which is provided upon its free end-portion with a handle 48. This stem or spindle 47 rotatably arranged in a bearing-portion 49 in the cap 39 and in a bearin '-socket 50 with which the previously-mentioned upwardly projecting part 37 of the main shell of casing is provided. Ifdesired, the said spindle 47 may be provided upon its portion outside of the cap 39 with an index hand or pointer, as 51, which is moved with the handle 48 and the stem or spindle 47 in either direction against su'itable' stops 52 and 53 with which the cap 39 is provided. the said stops being preferably indicated by the words Hot and Cold, so that the operator can readily turn the handlein the right direction to obtain either hot or cold water, or a proper mixture of the same. A coiled spring 5% may also be used, said spring encircling a portion of the spindle or operating stem 47, having one end-portion secured to-said stem 47 and the other endportion to said projecting part 37, the purpose of the said spring being for returning the operated stem -17 and its handle, as well as the spindle l5 and its parts, to their normal initial positions. lhe arrangement of the valve-disks and their stems, as well as the arrangement and (amstrnction ot the cam-member t'or actuating said valve-stems and v'alv'e-diskm is the same as herein-before described in connection with Figs. 1, 2, 3, 4, and 8 of the drawings, and need not, therefore, be again described in detail.

Having in the foregoingset forth the general construction of a combination taucetor mixing valve made according to and embodying the principles of the present invention, I will now briefly set forth its manner of operation for drawing a supply of either hot or cold Water, or for drawing any dc sired mixture of hotand cold water.

Referring now to Fig. 1 of the drawings, it will be evident that when the handle or lever 16 of the spindle 15 is moved in a forward direction, from right to left, looking toward the main shell or easing; 1, the camsurface 24 is immediately brought into sliding engagement with the pointed end por t-ion 32 of the right-hand valve-stem 31, whereby the valve-disk 33 is moved off its valve-seat 34, so that a supply of water, say the cold Water, is free to pass from the chamber 10, at the right-hand end of the shell or casing 1, through the passage-way 13, into the chamber 9 and out of the nozzle or outlet 14. The distance that the valvedisk 33 is moved away from its seat 34, to regulate the quantity of the flow of the cold water into the chamber 9, and from the nez zle.14, is eont-rolled by the convexity of the. moving cam-surtace 24, so that when the cam surface 23 has been moved into engagement with the end-portion 82 ot the righthand valve-stem, the valve-disk has been moved to, its t'hll extent and the maximum supply of cold water tlows through the opened valve. This happens with about; one-eighth of a turn of the handle 16 and spindle 15. \Vhen it is desired to temper the cold water, a regulat'able quantity of hot water may be added. by contim'liiu, the direction of the movement of the handle from-right to left, the righthand valvestem and valve disk being still maintained in their open relations, but the Hat surface 2!) is gradually brought into its active engagement with the pointed end-portion 39, of the left-hand valve-stem 31, which is operated so as to move the lett-hand valvedisk from its seat to admit a regulated quantity ct hot water into the chamber 0, where it mixes with the cold water. and thereby suitably tempers the ater, as will be evident. By still continuing the move ment of the handle 34: from right to left, the cam-surizwe 30 is brought into engagement with the end-portion oi the letthand valve stem, whereby the left-hand valvedislt is moved from its seat to its fullest. e.x tent. and a combined maxin'mm supply oi cold and hot water will flow into the chamber 9, which passes out therefrom through the nozzle 14. When the handle 34; is returned to its normal initial position, the, springs 35, as will be evident, cotipcrate with the unseatcd 'alve-disl s to return them to their seated and closed positions, to thereby shut oil the flow ot' the water. In moving the handle from its normal initial position, in a rearward direction from right to left, the left-hand valve-stem and valve disk can be operated without unseating the right-hand valve-disk, so that a maximum supply of hot water may be obtained. Similarly. this supply of hot. water can be. tempered by continuing the said movement of the handle 31. whereby the fiat surface 28 and the cam-surface 30 can be brought into engagement with the pointed end-pow tion of the right-hand valve-stem, so as to unseat the righbhand valve-disk to admit a regulated supply o'tcold water which reduces the temperature of the (towing hot 1 Water. \Vilh the construction represented in Fig. 5 of the drawings, the same results can be made to take place, except that owing to the geared-arrangement of the. spindlesulitlcrential-1'otary movements of said spindles take. place, so that the valve-disks are more quickly unseated, with the same movement of the handle 48. the spring 5-1: returning the parts to their normal initial positions, as soon as the ()[Xl'ttltil' removes his or her hand from the handle 48, as will be clearly understood from an inspection of said Fig. 5.

lVhile my present invention is especially adapted for use as a hot. and cold water combination faucet, it will be evident that the device may be used as a mixing valve, for regulatably mixing difi'erent kinds of liquid.

I am aware that changes-may be made in the general arrangements and combinations of the various devices and parts, as well as 1n the details of the construction of the .same, Without departing from the scope of the present invention asset fol-thin the foregoing specification, and as defined in the clauses of the claim which are appended -ing chambers, each end-member being proided with an inlet-port, and the spindlereceiving chamber being provided with an outlet-port, partitions dividing said valve" receiving chambers from said spindle-receiving chamber, each partition having an opening providing a means of communication between the adjacent valve-receiving chamber and the spindle-receiving chamber,
