ELECTRICAL GAS-COCK.

SPECIFICATION forming part of Letters Patent N0. 6,386, dated .March 17, 1896.

Application filed June 20, 1895.

To all whom it may concern.-

Be it known that I, HARRY L. TYLER, a citizen of the United States, residing at Corning, in the county of Steuben and State of New York, have invented a new and useful Electrical Gas-Cock, of which the following is a specification.

This invention relates to electrical gascocks controlled by the ordinary push-button system and it has for its object to provide a simple and efficient device of this character designed to facilitate the turning on and off of the gas with the aid of low battery-power.

To this end the invention also contemplates an electrically-controlled gas-cock made of as few parts as possible, which is practically frictionless in operation and which is especially available for use in connection with such burners as the \Velsbach burner, the nature of which burner prevents the use in connection therewith of most of the ordinary electrically-controlled gas-cocks on the market.

lVith these and other objects in View, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the drawings, Figure 1 is a sectional view of an electrically-controlled gas-cock constructed in accordance with this invention. Fig. 2 is a similar view of a modified construction of the cock.

Referring to the accompanying drawings, the numeral 1 designates a substantially spherical valve-casing provided at the top thereof with an eXteriorly-threaded neck 2, to which is designed to be attached the burner in connection with which the cock is employed. The said spherical casing 1 has detachably fitted in the lower open end thereof a bottom cap 3, which is provided with a depending interiorly-threaded neck l, adapted to be connected to the gas-bracket or in the line of piping which supplies gas to the burner.

In the construction illustrated in Fig. 1 of the drawings the detachable bottom cap 3 of the valve-casing is provided with a centrallyarranged gas-passage 5 and a threaded socket G at the upper end of said gas-passage, which Serial No. 553,464. (No model.)

socket removably receives the lower exteriorly-threaded end of the tubular valve-supporting post 7, which conducts the gas from the inlet-passage 5 to the outletof the casing at the neck 2.

The upright tubular valve-supportin g post 7, that is arranged within the casing 1, is provided at an intermediate point between its ends with a transversely-arranged guideopening 8, in which is mounted to slide the valve-plug 9. The valve-plug 9 is provided therein with a valve-opening 10, that is adapted to be carried in and out of alignment with the passage through the post 7, and at its opposite ends the said Valve-plug is provided with the iron armature-tips 11, which are readily susceptible to the magnetic influence of the electromagnets 12. The electromagnets 12 are arranged exteriorly on diametrically-opposite sides of the casing 1 and are included in an ordinary push-button circuit, which provides means for alternately energizing the magnets to control the movementpf the valve 9 and thereby turn on or cut oif the supply of gas at will. The cores 13 of the magnets 12 are threaded at one end, as at 14, in the openings 15 in opposite sides of the casing and project slightly within the casing directly opposite and in line with the iron ends of the valve, so that the said valve will be easily influenced by the magnetic attraction of the magnets when energized.

From the construction described it will be obvious that when one of the electromagnets is energized the valve-plug will be sharply attracted in one direction by such magnet, and when the other of said magnets is energized the valve-plug will be sharply attracted in the opposite direction, so that the opening 10 in the valve-plug will be alternately carried in and out of alignment with the passage in the post 7 to effect the turning on and cutting off of the gas.

A modification of the construction just described is illustrated in Fig. 2 of the drawings, and in this modification the magnets, while located at opposite sides of the casing, are disposed obliquely in order to properly influence the movement of the ball-valve 16, which is arranged to play between the inner projecting ends of the cores of the magnets. In this modification the ball-valve 16 takes the place of the valve-supporting post and the valve-plug illustrated in Fig. 1 of the drawings, and when the valve is in position to cut off the supply of gas through the cook the same rests in the valve-seat 17 formed at the upper end of the gas-passage 5, through the bottom cap of the casing. Directly adjacent to and at one side of the valve-seat 17 the bottom cap 3 in the modified construction is provided with a valve-pocketlS, in which the ball-valve 10 is designed to rest when the same has been attracted by one of the magnets, so as to uncover the gas-passage 5 and allow the gas to pass through the cock.

The operation of the modified construction of cock is practically the same as in the construction illustrated in Fig. 1 of thedrawings, it being understood that when one of the magnets is energized, with the ball-valve resting in the valve-seat 17, the said ballvalve'will be lifted from the said valve-seat and caused to drop into the valve-pocket 18 thereby uncovering the gas-passage 5. W'ith the ball-valve resting in the valve-pocket 18 the other magnet when energized will attract the ball and lift the same out of the pocket 18, so that the same will be caused to drop into the valve-seat 17, so as to cover the gaspassage 5 and thereby cut off the supply of gas.

The many advantages of the herein-described construction of gas-cock will be readily apparent to those skilled in the art, and it will be understood that changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrifiing any of the ad vantages of this invention.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is

1. In an electrically-controlled gas-cock,the casing having an inlet gas-passage, a valve arranged to cover and uncover said passage, and opposite exteriorly-arranged electromagnets, the cores of which are de'tachably fitted in oppositesides of the casing in line with the valve, substantially as set forth.

2. In a gas-cock, the valve-casing having a bottom inletpassage, a tubular valve-supporting post arranged in line with the inletpassage and provided at an intermediate poin t with a transversely-arranged guide'opening, amagnetically-movable valve-plug arranged to slide in said guide-opening and provided with a valve-openin g, and oppositely-located eleetromagnets having their cores disposed in line with the ends of the valve-plug, substantially as set forth.

3. In an electrically-controlled gas-eock,tl1e Valve-casing having a bottom inlet gas-passage, a tubular valve supporting post arranged within the casing and communicating with the gas-passage, said post being provided at an intermediate point with a trans:

versely-arranged guide-opening, a magnetically-movable valve-plug arranged to slide in said guide-opening and provided therein with a valve-opening, and the oppositelydocated electromagnets, the cores of which are detachably fitted in opposite sides of the casing in line with the ends of the valve-plug, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
