' NITED STATES ATENT ()FFICE.
JOHN F. LARKIN, OF MANCHESTER, NEW HAMPSHIRE.
SELF-CLOSING STOP-COCK.
SPECIFICATION forming part of Letters Patent No. 408,418, dated August 6, 1889.
Application filed March 1889. Serial No. 302,002. (No model.)
To aZZ whom it may concern.-
Be it known that I, JOHN F. LARKIN, a citizen of the United States of America, and a resident of Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Self-Closing Stop and aste (Jocks, of which the following is a full, clear, and exact description.
This invention in self-closing stop and wastecocks consists in details of parts and their combination and arrangement, all as will hereinafter appear.
In the drawings forming part of this specification, Figure 1 is a side elevation. Fig. 2 is a central vertical section. Figs. 3 and 4 are horizontal transverse sections, lines 3 3 and 4 4, Fig. i.
In the drawings, A is the case or shell, cylindrical in shape and having a water-inlet passage B and water-outlet passage Oin line with each other and on opposite sides of the shell, and both adapted forpipes (not shown) to be connected with them, and the one B with a water-supply pipe and the other C with a water-delivery pipe for the use of the water, as may be desired.
D is a water way or passage within and connecting water inlet and outlet passages B C of the shell, so that when opened, as will hereinafter appear, the water entering at the one B can pass to and out of the other C, and
- not otherwise.
E is a valve, having a valve-stein F extended through the top G and to the outside of the shell.
H is a coiled springsurrounding valve-stein F, and confined end to end between the valve E and the top G of case.
J is a seat for the valve E, and K is awaterway through said seat in communication with the waterways B and C of the shell D, so that when the valve E with its face E is seated, the Water-communication D between the inlet and outlet passages B C ofthe shell is closed to the passage of water, and when the valve is raised from the seat J said water-communication D is opened. The coiled spring II closes the valve E, as stated, and the valve is opened against the spring by power applied to the projecting end F of the valve-steln F,
which, for convenience, is to have suitable operating mechanism, to be suit-ably connected, as desired.
The operating mechanism for the self-closing valve E shown consists of a lever L, to which the valve-stem is pivoted, as at M, and which otherwise is arranged at one end to work on the top of the shell as its fulcrum, and at its other and free end 0 to have a chain or other connection made with it, as desired. The valve E has at its opposite end to that of its face E a face E, to seat upon a seat P of a horizontal partition Q of the shell, and dividing it into upper and lower compartments A and A This seat P hasawaste-water way P through it which is closed when the valve E is opened by the face E bearing on the seat P, and is opened when the valve E with its face E is on the seat J.
R is a waste-water-way passage leading from the upper compartment A of the shell A, and adapted, preferably, for suitable pipe-connection (not shown) to be made with it. With the self-closin g valve opened against its spring and seated on its seat P, a supply of water is thenfurnished through the water-passage B of the shell, as may be desired; and wit-h the self-closing valve closed and seated on its seat J the supply of water stated is shut off, and the water then contained in the pipe-connections of the water-outlet passage Got the shell passes through and out of the shell A at its waste-water passage R, all, as is obvious, without further explanation.
The self-closing valve E has an up-and-down movement, guided by its stem and top of shell, and also by fixed but separated vertical ways S of the shell and surrounding the valve, and at and about the waste-water way I of the valve-seat P. Both seating-faces E E of the valve are to have suitable leather or other packing washers T, and again the valve-stem and top of shell A are to be suitably provided with leather or other packing washers U, all as well known.
Under this invention and as appears from the description and drawings, the valve held on the valve-stem has a seating-face at each of its opposite end portions, and both seating-faces are in fixed planes in relation to each other, crossing the axialline of the valve and its stem, and the valve-shell has two on valve-seat J and to open and close waseating-faces, both fixed in relation to each other and situated so that the valve itself seated on either one thereof shall be off of the other face, and the valve, in opening and closing water-communieation D, moves directly in the one case 01f of the valve-seat of said communication and onto the valve-seat of the water-communication P and in the other case off of the valve of water-communication P and onto the valve-seat of the water-communication D, and in both movements without rub, wear, or friction on either seating-face of the valve or either valveseat; and, again, the water-communieations D P are the one opened and the other closed simultaneously, and the opening of watercommunication D and closing of water-co1nmunication P is against, and the opposite movements are with the action of the coiled spring H, bearing at one end directly on the valveall important for a practical and efficient working of the valve for the purposes stated.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
In a self-closin stop and waste cock, consisting of a shell or case A, having water inlet and outlet passages B C, and interiorly a water-passage D, connecting said passages B C, a valve-seat J, water-passage D, a valve E, having at one end portion a face to seat ter-passage D, and at its opposite end portion a stem passing, suitably packed, to the outside of the valve-ease, a spiral spring coiled about valve-stem and confined so as to hold the valve closed and to allow it to be opened, and means outside the valvecase to open the valve against and to allow the valve to close with the actionof said spring, the combination of a water-chamber A surrounding said valve-stem and its spring, an outlet R, for waste-water, leading from said chamber, a fixed cross-partition Q, of and located within the valve-ease A, between said waste-water outlet R and said valve E, a Water-communication P through said partition and connectingwater-chamber A with water-passage D and receiving the valve-stem and its spring, a seating-face P of said partition toward the valve E, and a seating-face E of the valve to seat on said face P of partition Q, and located at the opposite end portion of the Valve to that of its seating-face E for the seat of water-passage D, substantially as described, for the purposes specified.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
JOHN F. LARKIN.
