CHARLES G NYE, OF SYRACUSE, NETV YORK.

APPARATUS FOR AUTOMATICALLY CUTTING OFF GAS FROM BURNERS.

SPECIFICATION forming part of Letters Patent No. 327,963, dated October 6, 1885.

Application filed November 26, 1884. Serial No. 148,959. (No model.)

T0 on whom it may concern:

Be it known that I, CHARLES G. NYE, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Apparatus for Automatically Cutting off Gas from Burners, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The object of this invention is to guard against waste of gas incident to the neglect of persons leaving the room without shutting off the gas; and to that end my invention con-. sists, essentially, in the combination, with the gas-burner and the door of the apartment containing said burner, of a bolt on the door, a lever arranged to be actuated by said bolt, and mechanism for transmitting motion from said lever to the valve controlling the flow of gas to the burner, all as hereinafter more fully described, and specifically set forth in the claims.

In the annexed drawings, Figure 1 is a View of the interior of an apartment equipped with my invention. Fig. 2 is an interior view of the strike or catch plate of the lock, showing the lever which is actuated by the bolt and transmits motion to the valve of the gas-pipe. Figs. 3 and 4 are respectively front and side views of the aforesaid valve; and Fig. 5 is a View of the interior of the strike with the lever removed, to show the stop which limits the movement of said lever.

Similar letters of reference indicate corresponding parts.

A represents a gasfixture, of any ordinary and well-known style, screwed to the gas-pipe B, and provided with burners O G.

t denotes a valve connected with the gaspipe above the gas-fixture, and provided with the usual key-head, k, by which to turn said valve. A spring, s, is connected at one end with the valve and at the opposite end with the case of the valve or with some other stationary object, and is bent in such a manner as to cause it to normally turn the valve into an open position. On the key-head k of the valve I clamp, adjustably, a metallic band, a, bent into the shape of a lever or segmental bow, and having its extremities fastened conjointly on the key-board at oneside of the axis thereof by a screw, 6.

Another screw,

6, passes through the band 0 and engages the key'head at the opposite side of the axis thereof. By means of this latter screw the keyhead It can be set at different angles in relation to the lever-shaped band a, and thus made to shut off the gas to a greater or less degree by the turning of said cam, as hereinafter de scribed.

D represents the door of the apartment con taining the gas-fixture with its burners, and Z denotes a lock attached to said door, which lock may be of any ordinary and well-known style, having a bolt entering a catch-plate or so-called strike, m, and adapted to belocked and unlocked from the outside of the door. In the strike m is pivoted a lever, a, one of the free ends of which is arranged to be encountered by the bolt entering the strike in locking the door. To the opposite end of said lever is attached a wire or cord, d, which is extended through an aperture in the strike, and thence in a suitable manner to the lever c, which is connected with the valve 22 on the gas-pipe, said wire or cord being connected with the lever a in such a manner that a draft on the former turns the latter, and thereby also turns the valve in the direction to shut ofi' the gas. The lever a, Iprefer to make of segmental form, and pivot the same at the center thereof, thereby making it reversible, and adapted to be used in connection with either a right or left hand lock. The interior of the strike m, I provide with a rigid lug, 1), arranged to encounter flanges on the ends of the lever a, and thus limit the movement of said lever.

\Vhen the door is unlocked, the lever a is relieved of the pressure of the bolt of the lock, and the spring sis thus allowedfftoIholdZthe valve 21 in an open position; hence when the person is within the apartment and leaves the door unlocked the operation of the gas-fixture is undisturbed, and the light can be controlled by the cocks with which the fixture is usually provided. Should the person leave the apartment without turning down the gas,upon closing the door and looking it from the outside the bolt of the lock strikes the lever a, and thereby turns the same into the position illustrated by full lines in Fig. 2 of the drawings.

The turning of said lever produces a draft on the wire or cord d, which latter turns the lever 0, and with it the valve 12, so as to shutoff the gas.

By means of the screw 0 the lever 0 can be so adjusted as to cause the same to turn the valve 1) a greater or less distance, and thus shut off the gas to a greater or less degree, the intention being to retain a small flame. Upon unlocking the door the lever a is relieved of the strain from the bolt,and the spring 8 then restores the valve to its open position, to allow a full flow of gas to the burners.

I do not limit myself to the specific form of the levers a and c, as shown in the annexed drawings, as it is obvious that the same is susceptible of many modifications, and that cranks and other mechanical equivalents can be employed in lieu of the described cams; neither do I wish to limit myinvention to the location of the lever a in the catch-plate or strike m, inasmuch as said lever or its equivalent can be arranged at other points in proX- imity to the door, so as to be actuated by the same in opening and closing it.

I am aware that prior to my invention the supply of gas to burners has been regulated by an oscillating platform arranged near the door of the apartment containing the burner, which platform was connected with the burners by suitable levers and rods, and was actuated by a person stepping upon said platform. It is obvious that such a device either necessitates cutting into the floor an opening for the reception of the platform or presents an obstruction on the floor when placed over the same. leaves the floor smooth and solid, and is in a position where it is comparatively safe from tampering and breaking.

WVhat I claim as new, and desire to secure by Letters Patent, is

1. In combination with the gas-burner and the door of the apartment containing said burner, a bolt on the door, a lever arranged to be actuated by said bolt, and mechanism for transmitting motion from said lever to the valve controlling the flow of gas to the burn er, substantially as set forth.

My invention is more easily applied,

2. In combination witha gas pipe and burner connected to said pipe and the door of the apartment containing said burner, a valve connected with the said gas-pipe and held normally in an open position, a lever connected with said valve for turning the same, a lock on the door, adapted to be operated from the outside of the door, a lever connected with the strike or catch plate of the lock, and adapted to be actuated by the bolt of the lock, and a wire or cord connecting the said lever with the lever of the valve, substantially as specified and shown.

3. In combination with the gas pipe and burner and the door of the apartment containing said burner, the valve 1), provided with the key-head k, the lever 0, attached to said key-head, the spring .9, arranged to normally hold the valve in an open position, the lock Z, arranged to be opened from the outside of the door, the lever to, pivoted in the strike in and arranged to be actuated by the bolt of the lock, and the wire or cord d, connecting the levers a and 0, substantially as described and shown- 4. I11 combination with the gas pipe and burner and the door of the apartment containing said burner, the valve 1), provided with the key-head 7c, the levenshaped metallic band 0, adj ustably connected with the keyhead by screws 0 e, the spring 8, arranged to normally hold the valves in an open position, the lock Z, arranged to be opened from the outside of the door, the lever a, pivoted to the strike m, and arranged to be actuated by the bolt of the lock, and the wire or cord d, connecting the levers a and c, all constructed and combined to operate substantially in the manner shown and set forth.

In testimony whereof Ihave hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county ofOnondaga, in the State of New York.
