GAS-COCK.

SPECIFICATION forming part of Letters Patent No. 566,590, dated August 25, 1896.y Application iiled December 5, 1894. Renewed January 4, 1896. Serial No. 674,391. (No model.)

To @ZZ whom, t may concern:

Be it known that I, ERNST LINDNER, a citizen ot' thellnited States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gas-Cocks, of which the following is a specification.

My invention relates to gas-cocks, and particularly where the cock is combined with the coupling-piece, which is adapted to be connected to the pipe supplying the gas and also to the bracket carrying the burner.

The object of my invention is to simplify and chea pen the manufacture of such devices, wherein there is combined with the coupling-piece a lateral branch adapted to connectwith the tubing of rubber for supplying gas to a drop-light, gas-heater, or the As usually constructed the cock controlling the supply or' gas through the lateral branch is placed within a casing or globe formed as a part of the lateral branch. This increases the cost and diiiiculties of manufacture, since it requires, in addition to the globe-casing between the coupling ends of the device, and from which casing the latter branch extends, an independent globe-casing in said lateralbranch to receive the cock controlling the gas supplied through said branch. By my invention I dispense with one of these globe-casings, utilizing' the globe-casing between the coupling ends of the device for the cock regulating the supply of gas to the lateral branch. In the manufacture of my gascock all the parts are made from a solid bar or rod of metal on a suitable lathe, no casting whatever being made use of, and hence expense of finishing the device by polishing, ttc., is avoided.

jin embodiment ot my invention is shown in the accompanying drawings, in which like parts are indicated by like letters of reference in all the views, and wherein- Figure l is a viewln perspective showing a gas-bracket provided with niy improved gas-cock. Fig. 2 represents a vertical sectional view through the globe or shell between the coupling ends of the device and longitudinally through the lateral branch, the gate-key and its thumb-piece being in side elevation. in this view, as well as in Fig. l7

the thumb-piece is shown at the top of the casing, though when in use it will ordinarily be at the bottoni. Fig. 3 is a horizontal longitudinal sectional view on the line 2 2 of Fig. 2.

Referring to the drawings, o indicates' the central enlargement or globe-casing of the device Z) a cou'pling end, which is adapted to connect with the gas-supply pipe and is screwthreaded internally, as shown, for that purpose, and c the coupling end externally screwthreaded and adapted to receive the bracket provided with the gas burner or burners. The casing a is provided centrally and vertically with the valve-seat, which is tapered, as shown, in the usual ina-nner to receive the tapered gate-key d, and which latter is secured within its seat by a nut c or equivalent means.

That portion of the gate-keyf outside of the casing is of a round configuration and is provided with a thunib-piece g of any suitable design. The shank d of the gate-key is also provided outside of the casing with a stop h, whereby the revolving motion of the gate-key within the casing is controlled and limited. The shank d is likewise provided with a passage through it laterally, as indicated at 1'.

The casing a is formed with the lateral eX- tension k, having a channel through it conimunicating at its inner end with the coupling end b, and the outside surface of the lateral branch or extension 71: may be corrugated or similarly formed to facilitate the retention of the rubber tube thereon. The casing o is also provided with a through-passage lin the rear of the wall of that portion of the casing through which the vertical valve-seat is made. The passage l connnunicates with the coupling ends o c, and is adapted to supply a continuous llow of gas to the burner on the bracket which is secured to c, the cock controlling the supply to the burner being on the bracket. The supply of gas to the lateral branch 7e is controlled by the suitable adjustment of the key d within the casing. ln both views the key d is adjusted to permit the ilow of gas through the lateral branch k.

It is obvious that by reversing the key its lateral opening 'L' will be out of register with the passage through the lateral branch k and the solid portion of the key will etfectually close such passage.

IOO

By my present invention, whereby the means for controlling the supply of gas to the lateral branch are located within the casing a, through which also extends the passage for the supply of gas to the burner on the bracket, I produce a compact and cheap fixture, all

the parts of which, as before stated, beingl 2. A gas-cock consisting of a central globe or casing, provided with coupling ends and a lateral branch or extension, the latter having a through-passage communicating with one of said coupling ends and the casing having a through-passage communicating with both coupling ends and a central valve-seat, in combination with a gate-key fitted within the seat of the casing and provided with a lateral opening adapted to register with the passage- Way through said lateral branch, substantially as set forth.

Signed at New York, in the county of New York and State of New York, this 13th day of November, A. D. 1894.

ERNST LINDNER.
