ALFRED HUMPHREY, OF NEW YORK,
GAS-COCK-OPERATING DEVICE.
incense.
To all whom it may concern.
Be it known that I, ALFRED H. HUM- PHREY, a. citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Gas-Cocl()per'ating Devices, of which the following is a specification.
My invention relates to that class of device in which illuminating gas may be turned on and off by the simple pulling of a depending chain or cord,each downward pull turning the gas-cock one quarter around so that alternate pullsopen and close the cock. It is preferably applied to that style of gas jets in which a pilot flame is kept constantly burning so that the gas may ignite as soon as it is turned on.
The object of my invention is to provide a simple, durable, and sightly, gas-cock operating device which will not readily get out of order and which can be easily ap plied and removed from the gas jet if occaslon requires.
In the accompanying drawings :-Figure 1, is a front elevation. Fig. 2, is a vertical section on line 22, of Fig. 1. Fig.3, is a section on line 33 of Fig. 2. Fig. 4, is a plan. view of the chain wheel or pulley. Fig. 5, is a detail of the spring friction disk against which the chain wheel bears with proper tension and serves as a clutch to cause the cock to turn when the chain is pulled.
Same letters indicate similar parts in the different figures.
A, represents a fitting or cock-body of usual construction, provided with the sprin gmounted tapering plug B, with the channel 0., adapted to allow gas to pass from the inlet 6, to the jet opening 0, when in the position shown in Fig. 2.
C, is an adjustable pilot flame fixture of usual construction.
D, is an open shell formed as a projection on the body of the gas-cock A, to serve as a support and gripping device for the re movable shell E. These two shells form a casing in which the cock-turning devices are placed and by which they are covered and practically protected from dust, moisture, and all outside interference,the operating chain passing through a bell-shaped tube 0?. These two parts of the casing are Specification of Letters Patent.

preferably telescoped, the removable portion being simply held by the pressure of the fixed portion, but they may be otherwise interlocked or fastened. if preferred.
The stem 0, of the cockB, is internally screw-threaded to receive the screw f, which fastens the springfriction disk F to the stem e,-said disk having a central opening m, with a squared side 71, which fits a squared shoulder on the stem 6, so that when the disk is turned the stem is also turned to open or close the cock. This friction disk F, has a number of notches or slits running in from the circumference, the metal being slightly turned as shown in the drawing to balls of the chain J, lie in the grooved periphery of the wheel G,one of the balls being caught in the fork j. o
The swing of the chain wheel, is limited to a quarter circle by the lugs 70, is, which come against the fixed stop Z, downwardly projecting on the inside of the shell D. The chain wheel is normally held in the position shown in Fig. 3 by the pull of the coiled spring H. The friction exerted when the chain is pulled is sufficient to make the disk F turn with the wheel, but the configuration of the disk is such that it does not press against the wheel with sutlicient force to prevent the wheel from turning back freely when the chain is released. When the chain is released the chain wheel turns back a quarter circle but does not carry the stem 6, with it as the spring-mounted plug exerts suflicient friction to prevent.
The operation of my improved device will, I think, be readily understood without further description.
I claim 1. A gas-cock operating device consisting of suitable devices, mounted upon the cockstem, whereby the cock is opened and closed as desired, and an inclosing shell consisting REISSUED of a sliding section and a stationary sect-ion loosely mounted on said stem and a shell mounted upon a projection of the gas-jetadapted to cover and protect the same and body adapted to grip and support said slidsupported by the gas-jet-body.
