ARTHUR I-I. MARSCHER, OF MEMPHIS, NEW YORK, ASSIGNOR TO THE SYRACUSE FAUCET AND VALVE COMPANY, YORK, A CORPORATION OF NEW YORK.

OF SYRACUSE, NEW

VALVE.

SPECIFICATION forming part of Letters Patent No. 691,400, dated January 21, 1902.

Application tiled April 8, 1901.

T0 all whom, it may concern:

Be it known that I, ARTHUR H. MARscHEE, acitizen of the United States, and a resident of Memphis, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Valves, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention resides in a valve which is particularly intended to be used in connec tion with a'tank or other receptacle for controlling its supply or discharge, it being employed in the present instance for theformer purpose, although it is adapted to be used for various other purposes.

The invention also resides in the novel construction of the mechanism for operating the same.

The main object of the present invention is to produce a valve which shall be simple, strong', and durable in construction, quick and reliable in its action, and at the same time shall permit the valve proper to be easily removed and replaced, 'whereby the valve can be readily cleaned or repaired when re quired; and, furthermore, the object of the invention is to provide simple and reliable operating mechanism which can be easily and conveniently actuated by hand when desired and can be readily attached to various devices, whereby the same shall be actuated automatically.

To these ends the invention consists in the novelvconstruction and combination of parts, as hereinafter fully described, and set forth in the claims.

In the drawings, Figure 1 is a vertical transverse section of a water-tank provided with my improved valve and mechanism, which valve is employed for supplying the said tank, the same being shown attached to tudinal section on line W WV in Fig. 3. Fig. 5 is a transverse section on line X X in Fig.

Serial No. 54.818. (No model.)

4. Fig. 6 is a transverse section on line Y Y in Fig. 4, and Fig. 7 is a transverse section on line Z Z in Fig. 4.

Referring to the drawings, A represents a water-tank, which maybe of any wellknown shape or construction, as it does not in any Way pertain to the invention.

My improved valve comprises the casing B, which may be of any suitable shape or design. Said casing is screw-threaded internally and is formed at one end with a stem or shank a, which passes through the bottom or side of the tank and is secured firmly thereto by means of a nut b, applied to the screw-threaded end portion of said stem or shank and bearing against the outside of the tank, as clearly shown in Fig. l. The said stem or shank a is formed with a longitudinal passage c, constituting the inlet communicating with the casing. casing is formed a thimble d, formed with a longitudinal passage e, which constitutes the outlet. Said thimble is preferably screwthreaded externally for the attachment of an elbow -pipe f, which is used when the valve is secured to the bottom of the tank to direct the water downward. By forming the said thimble with screw-threads it serves to permit the valve to be used for various purposes. (Not necessary to be stated.)

C denotes a plug which is composed of an. upper or outer screw-threaded portion g and a similar screw-threaded lower or inner portion It, by which threads it is turned into the casing and is thus removable therefrom. By constructing the plug in this manner an annular chamber il is formed at the central portion`of the plug, which chamber communicates with the outlet e. The inner portion h of said plug is formed with an outwardly-flaring passage a', extending from the inner end yof the plug to the chamberi and is preferwhich is formed with its engaging face smooth, .so as to form a tight joint with the seat, and

is provided with a port d at one side, which is preferably of segmental shape and is adapt- On the side of the p ed to register with the lower end of the aforesaid passage a of like shape, as hereinafter more fully described. i

e denotes the stem, which passes freely through a central longitudinal channel f', formed in the plug C, and is detachably connected at its inner or lower end to the aforesaid valve c. Said connection of the stem and valve is as follows: The valve is formed with a central opening q' and with two short radial slots t" fi', extending from said opening in opposite directions, and in the lower face of the valve are formed two recesses 71. h', extending from said opening in opposite directions and at right angles to the said slots. The stem is formed at its inner end with two lugsjj, projecting at right angles therefrom and in opposite directions. Thus in assembling said parts the stem is inserted through the opening g and its lugs j j made to pass through the slots i fi', and the stem is then given a quarter-turn to bring the lugs into position to register with the aforesaid recesses h 7L. The upper or outer end portion of the stem e is screw-threaded, to which is secured a bevel-pinion d2, which abuts against a shoulder d3, formed on the stem, which shoulder serves to prevent the pinion from turning down on the stem when power is applied thereto, as hereinafter described.

The outer end of the plug C is formed with a central socket b2, through which the stem passes, and in said socket is a coiled spring c2, surrounding the stem and bearing against the inner face of the pinion,whereby the stem is drawn outward to cause its lugs jj to enter the recesses h' h in the valve. Thus said stem is locked to the valve and the said valve held firmly to its seat on the inner end of the plug. The said spring bearing on the inner face of the pinion and drawing out the stem also holds the pinion out of contact with the outer end of the plug, thus preventing friction between the two parts. To the outer end of the stem is applied a jam-nut cl2, which bears on the outer face of the pinion, and thus serves to prevent said pinion from turning off the stem.

Upon the casing B is mounted a pair of brackets ci e2, which are preferably of triangular shape and are secured to plates fzfg, formed on the casing, by means of screwbolts g2 g". To the outer ends of said brackets is secured a stationary shaft h2, and on said shaft is journaled a depending oscillatory quadrant 2, which is formed with a segmental gearf, meshing with the aforesaid bevel-pinion a2. On the hub of said quadrant is formed an arm b3, projecting therefrom at right angles, which arm is formed with a longitudinal screw-threaded socket of and with a transverse screw-threaded socket d3.

D represents a float disposed within the tank A and which may be of any suitable form and is connected to the aforesaid quadrant by means of a rod e3, which is screwthreaded at each end. When the valve is attached to the bottom of the tank A, the said rod e3 engages the longitudinal socket c3 of the arm b3, and when the valve is attached to the side of the tank the rod engages the transverse socket d3 of the arm, which latter connection is illustrated by dotted lines in Fig. l. In order to prevent the segmental gear from p being crowded out of mesh with the bevelpinion, I provide set-screws ff, passing through one of the brackets e2 and bearing on the outer side of the quadrant, as clearly shown in Figs. 2 and 3.

The valve c' is formed on its'lower face, at the central portion thereof, with a housing g3 over the attachment of the stem thereto, which housing serves to prevent escapement of the water betweenthe stem and plug.

The operation of my described valve and its actuating mechanism is as follows, to wit: When the float is in the position shown, the port of the valve proper registers with the vertical passage of the plug, which communicafes with the central chamber, which in turn communicates with the outlet, (clearly shown inFigs. l and 4,) whereby the Water is allowed to pass from the inlet to the outlet into the tank. The rise of the water causes the float to ascend in the well-known manner, whereby motion is imparted to the quadrant by means of the connecting-rod, and the segmental gear on said quadrant meshing with the bevel-pinion rotates the stem, thereby turning the valve to cause its port to be moved gradually out of register with the vertical passage of the plug. Therefore when the float has reached a predetermined height the communication between said port and passage will have been entirely closed, and thus the supply of water cut off. It will of course be understood that as the water in the tank drops and the float descends thus the various mechanisms are operated in the manner described and the valve is again opened.

I do not wish to be limited to the employment of the mechanism shown and described for operating the valve, inasmuch as other means may be used, and in instances where said mechanism is employed I do not wish to confine myself to the use of a oat for controlling said mechanism, as many other devices may be combined with the same.

It will be seen that in cases where it is desired to operate the valve by hand a short rod may be substituted for the rod shown attached to the quadrant, said short rod serving as a lever, and, furthermore, if desired, the gearing may be entirely dispensed with, and in this case a hand-lever can be attached directly to the valve-stem and a nut substituted for the bevel-pinion to form a bearing for the coiled spring.
