STOP AND WASTE COCK.

SPECIFICATION forming part of Letters Patent No. 283,613, dated August 21, 1883.

Application filed Dccemherlfi, 1882. (No model.)

To dz; whom it may concern:

Be it known that I, Joruv KELLY, of Chicago,

in the county of Cook and State of Illinois, have invented certain new and useful Inoprovements-in Stop and Waste Cocks, and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and

' t) the letters of reference marked thereon,

devices and combinations of devices that constitute the stop cook or valve and its operat ing appurtenances, as hereinafter described and specifically claimed. I

In the accompanying drawings, Figure 1 represents an elevation of my stop cook or valve and itsconnections for operating the same; Fig. 2, a transverse section on line a: .70

- in Fig. 1; Fig. 3, a detached sectional view of the cord-clamp, and Fig. 4C a longitudinal vertical section of the stop cook or valve.

Corresponding letters in the several figures of the drawings designate like parts.

A denotes apip'e that has formed a conical valve-seat, a, in one end, and is exteriorly screwthreaded to engage the couplingring b, that connects the nozzle B, to which the supplypipe is to be soldered. At a another conical valve-seat is formed in pipe A, whence such pipe is expanded and is exteriorly screw-- threaded for connecting the internally-screwthreaded mouth d of crank-chamber C. To a branch nozzle, 6, between the valve-seats a and c, is connected by a screw-collar, f, the pipe D,.

that leads to the several faucets and valves in the rooms of the house. The screw-nozzle g of crank-chamber O, that is opposite the mouth d, connects with an elbow-nozzle, E, by a screw-coupling, 6. Whenever the water-supply is shut off, by closing valve 19 valve 0 will be opened, when the water contained in the several pipes of the house will run off through nozzle E either into the ground or into the sewer, with which such nozzle can be connected by a pipe, Through an opening in one side of chamber 0 is inserted a crank, F, having conical collar 3', that shoulders against the rim of such opening, and concentric with this opening is provided an internally-screwthreaded socket, K, for attaching the stuffing-box sleeve B, through which the stem Z of crank Fis projected, and that is filled with packing for forming a hermetic joint around such crank-stein Z. The projecting portion of such crank-stein Z is formed square for connecting a lever (shown in dotted lines in Fig. 1) that carries a weight, G. I

The valve-rod H has a curved and eyed end, at, that engages with crank-pin n. This valverod H is tapering and screw-threaded for se' curing the conical or semi-globular valves 0 and p, that are made of hard rubber, and are to form hermeticjoints with the valve-seats a and c. The valveo is adj ustably held between a small screw-collar, q, and the flanged nut 0-, and the valve 19 is adj ustablysecured between a small screw-"collar, s, and wing-nut t, and both valves 0 and p are secured upon such valve-rod H, to be farther apart than the dismanner that with closing one valve upon its seat the other valve will thereby be opened. The wing-nut t, in the manner it is constructed, not only forms a thumb-nut, but also a guide for the valve 1) in nozzle 13. The water entering pipe A through valve-opening a, the pressure of the water is against valve 1), and therefore such valve would be naturally closed by such water-pressure, and will be forced against its seat. released, tends to close such valve. This weight G, I connect by a cord, I, with the eyed end of a cylindrical bar, L, that has to its middlea rectangular handle, a, and is guided in two eyebrac-kets, M and N, the upper one of which is provided below its guide-eye with side lugs, '0, that willallow the handle a to pass between while held forward, and upon either one of giving it a quarter-turn for holding the bar L on an elevated position. By this bar L the tance between the valve-seats a and c, in a Besides, the weight G, when which lugs e such handle will be supported by I soon as released, by turning the handle a toward the front to pass between the lugs 11, the

rod L will drop until its handle it rests upon the eye of bracket M, when the weight G will swing downward and the crank F will pull the valve-rod to close valve 19 and open valve 0. The cord I is guided over as many pulleys J as necessary between weight G and bar L to lead it to the desired position of bar L. The cord I is preferably of wire, and its upper loop connection with bar L, for proper adjustment, I prefer to tie with a nut, O, that is sleeved over the looped ends of the cord, and has a set-screw, w, by which the cords are clamped together. The stop cock or valve has a screw-stud, i, that enters a screw-threaded socket of a bracket, 1?. This bracket I has a plate, 2, that is secured by wood-screws against the wall, or against one side of a box that is buried into the ground.

The pipe A and crank-chamber C can be connected or arranged in a different manner for providing the valve-seats in proper positions relative to pipe D and crank F from what has been shown and described herein, without changing the principle and general construction of my device, and therefore I do not wish to be restricted to the particular arrangement herein described and shown.

What I claim is I K 1.. In a stop-cock, the pipe A, having valveseats a and a, nozzle 13, adapted to connect with the supply-pipe, and branch 6 for coup- H, that carries valves 0 and p, and is pivoted 4c to crank F, the whole being constructed and arranged substantially as described, to operate as specified.

2. A stop-cock having branch 0, valve-seats a and c, and chamber 0, in combination with a and c, and chamber 0, with stuffing-box R,

in combination with valve rod H, having valves 0 and p, crank F, and weighted lever G, all constructed and arranged substantially as set forth, to operate as specified.

4. In a stop-cock, in combination with reciprocating valve-rod H, having valve 1), Wing nut 25, substantially as and for the purpose set forth.-

5. In combination with a stop-cock provided with crank F for operating the valves,

and with weighted lever G, rod L, having handle a and guided in eye-brackets M and N, the latter being provided with lugs v, and

the rod L being connected with lever G by a cord, I, all substantially as and for the purpose set forth. I

In testimony that I claim the foregoing as my invention Ia ffix my signature in presence of two witnesses.

JOHN KELLY.
