COMBINATION-FAUCET.

SPECIFICATION forming part of Letters Patent No. 763,827, dated June 28, 1904. Application tiled February 9, 1904:. Serial No. 192,761. (No model.)

T0 all whom, t nza/y concern.-

Be it known that I, SAMUEL S. WILLIAMSON, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain newY and useful Improvement iny Combination-Faucets, of which the following is a specification.

My invention relates to a new and useful improvement in combination-faucets, and has for its object to provide a faucet in which a plurality ofl Valves are adapted to be operated through the agency of one handle so as to allowA the liquid flowing through the valves to pass out of one nozzle.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which I Y Figure 1 is a Vertical section through my improved faucet; Fig. 2, a section taken on the line 2 2 of Fig. l; Fig. 3, a bottom plan view of the faucet, a portion of the casing being broken away to show the interior; Fig. 4C,

Aa section taken on the line 44 of Fig. 1; Fig.

5, a side elevation of the faucet; Fig. 6, a bottom plan View of the faucet in which only two valves are used, a portion of the casing being broken away. In this view the faucet is showninitsnormal position. Fig. 7 is a similar view to Fig. 6, showing one of the valves open and the other closed; Fig. 8, a similar view to Figs. 6 and 7, showing both of the valves open.

A represents the casing, which may be made in any shape desired, but preferably cylindrical. In the center of the casingis formed a cylindrical central chamber B. The space between the walls surrounding the central chamber and the outer casing is divided into different compartments C, there being one compartment for each inlet and valve. Beside the compartments for the inlets therek is a compartment D, with which the nozzle E below the valves.

ed to be normally held upon these seats by means of the springs H, surrounding the valvestem and interposed between the valve-disk G and the casing A. The valve-stems extend inward from the valve-disks Ginto the inner chamber B and are guided by the openings formed through the wall B. Of course the valve-stem, which extends through the openings in the wall B, could be made of spider form, so as to guide the valve, but still allow the liquid to pass from the chamber O, through the openings, into the inner chamber B; but in the drawings I have shown the valvestem which projects into the chamber B as being made in the form of a hollow cylinder {itting the openings through the wall B', the inner end of the cylinder being open,and formed through the walls of the cylinders are openings I, which openings normally lie within the central chamber B; but when the valvestems are pressed outward these openings will be forced outside of the wall B', so that the liquid may pass from the chamber O, through the openings I, into the central chamber. In order to operate these valves with a single handle, I provide within the central chamber B a disk J, fitting said chamber snugly. This disk may either lie above 0r Extending upward from this disk is a stem J', which passes through a suitable stufng box or cap K, and upon its upper end is secured the handle L. Secured eccentrically upon the disk J is a stud M. This stud M lies in such a position as to contact the valve-stems when the disk J is re, volved. If desired, a roller M may be mounted upon the stud. The valve-stem, disk, and stud form a crank, the stud being in reality IOO the wrist-pin of the crank. The valve-stems extending into the Vcentral chamber Bmay extend into said chamber at any angle or in any manner desired, but must not extend into the chamber farther than an imaginary circle drawn concentric with the disk .I and passing through the center of the stud M; but said valve-stems extend into the central chamber very nearly as far as this imaginary circle, so that when the disk J is revolved by the handle L the roller M coming in contact with the valve-stems will press the valve-stems outward and remove the valves G from their seats, and as soon as the openings I pass beyond the wall B the liquid will iiow into the y central chamber and out of the nozzle E.

As this faucet is intended principally and is adapted particularly for a bath-tub faucet, the valves will be arranged in pairs, the valvestems extending into the central chamber B in such a manner that the two valve-stems of each pair will be in close proximity to one another, so that the roller M will start to open one valve before the other is closed, and when the roller M is exactly in the center between both valve-stems both valves of that pair. will be held open an equal distance, and by moving the roller one way or the other one of the Valves may be opened more than the other. Thus as one of the valves will control the hot water and the other the cold the water may be mixed in any manner desired so that it may issue from the nozzle at the right temperature. Y

A faucet simply intended for hot and cold water is shown in Figs. 6, 7, and 8; but at seaside resorts and in places where mineral water is used it is desirable to have bath-tubs equipped with faucets whereby hot and cold ordinary water may be drawn or hot and cold salt water or mineral water, as the case may be, in which case it would be necessary to construct my faucet with four different valves, and such a construction is shown in Figs. 2, 3, and 4, the two valves for the fresh water being arranged in a pair and the two valves for the salt or mineral water also being arranged in a pair upon the opposite side. In such a case the disk would only be allowed to make one-half revolution in either direction, it being stopped by means of the pins O abutting against a stop O', extending outward from the wall B, and the top of the faucet would be marked as shown in Fig. 4, so that when the handle is turned to the side labeled Fresh the first valve, controlling the cold fresh water, will be opened, and then by turning the handle farther the cold and hot water may be mixed. Then by turning it as far as possible in that direction the hot water alone will flow, and by then turning the handle back to its normal position and then turning it in the opposite direction to the side labeled Salt hot or cold salt-water may be drawn.

It will be obvious that one of the advantages of this faucet will be that it will beimpossible for the user to scald himself, for the cold water must be turned on before the hot.

Of courseI do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful isl. In a faucet, a casing, inlet-chambers arranged within the casing, an outlet-chamber arranged within the casing, valves controlling openings between the inlet-chambers and the outlet-chamber, said valves arranged in pairs, a crank-shaft, the wrist-pin of said .crankshaft adapted to contact the valve-stems and remove the valves from their seats as the crankfshaft is revolved, each pair of valves being so arranged that the second valve will be opened before the first valve contacted will be closed, as and for the purpose specified.

2. In a faucet, a casing, inlet-chambers arranged within the casing into which the inletpipes extend, an outlet-chamber arranged Within the casing with which the nozzle is connected, valves controlling openings between the inlet-chambers and the outlet-chamber, springs normally holding the valves upon their seats, a crank-shaft journaled in the casing, the wrist-pin of said crank-shaft adapted to contact the valve-Steins and open the valves successively as the crank-shaft is revolved, said valves being arranged in pairs and in such a manner that the wrist-pin will open the second valve of each pair before the first valve opened has been closed, as specified. 3. In a faucet, a casing, a central cylindrical chamber arranged within the casing, a

nozzle connected with the central chamber, an even number of chambers arranged between the wall of the central chamber and the outer wall of the casing, an inlet-pipe extending into each of these outer chambers, the wall surrounding the central chamber provided with openings connecting the central chamber with each of the outer chambers,` valve-seats surrounding said openings upon the outer side, valves adapted to seat against said valve-seats and open outward, springs normally holding said valves upon their seats, valve-stems connected to the valves and extending through the openings into the central chamber, said valves arranged in pairs, a crank-shaft journaled concentrically with the central chamber, the inwardly-extending valve-stems not extending into the central chamber farther than an imaginary circle concentric with the central chamber and passing through the center of the wrist-pin of the crank-shaft, said wrist-pin, when the crank-shaft is revolved, adapted to contact the valve-stems of each pair consecutively so as to open the valves, and the valvestems of each pair so arranged that the wristpin will open one valve before the other is closed, so that each valve of each pair may be IIO opened separately, or both will open at the same time to a more or less degree, as Specified.

4. In a faucet, a casing, a central cylindrical chamber arranged within the easing, a nozzle connected with the central chamber, an even number of chambers arranged between the wall of the central chamber and the outer wall of the casing, an inlet-pipe extending into each of these outer chambers, the wall surrounding the central chamber provided with openings connecting the central chamber with each of the outer chambers, valve-seats surrounding said openings upon the outer side, valves adapted to seat against said valve-seats and open outward, springs normally holding said valves upon their seats, valve-stems connected to the valves and extending through the openings into the central chamber, said valves arranged in pairs, a disk iitted to revolve snugly within the central chamber, a stem extending upward from theeenter of the disk through the casing, a handle secured upon the upper end of the stem, a stud secured to the disk eceentrically, a roller mounted lupon the stud, the inwardly-extending valve-stems not extending into the central chamber beyond an imaginary circle drawn concentric with the disk and through the center of the stud, said roller adapted to contact the valvestems of each pair of valves successively as the handle is turned, the valve-stems of each pair of valves being so arranged in close proximity to one another that one valve will be opened before the other is closedso that each valve of each pair may be opened independently, or both valves of each pair may \be opened at the same time to a more or less degree, as specified.
