AUTO MATlC GAS-EXTINGUISH ING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 392,921, dated November 13, 1888.

Application filed May 2, 1888.

To all whom it may concern/.-

Beit known that I, Runes HOWARD, a citizen of the United States, residing in Salt Lake City, Utah Territory, have invented certain Improvements in Automatic Gas-Extinguishing Apparatnses, of which the following is a specification.

My invention relates to that class of devices or apparatuses which are designed to extinguish a gas-light ata certain hour, and the ob ject is to provide a simple and eflicient device that may be mounted on an ordinary gas burner and connected with an ordinary alarmclock, such as may be purchased in any city for a small sum.

My apparatus is designed to be wound up and connected on the one side, by a cord or other connector, with the gas-cock, and on the other side, by a cord or similar connector, with the vibrating hammer of an alarm-clock. The first movement of the hammer when the alarm sounds releases the spring of the extinguisher and allows it to wind up or actuate the connector attached to the gas-cock, and thus shut off the gas.

In the drawings, which serve to illustrate my invention, Figure l is a general view on a small scaleshowing the relative arrangements of the gas jet and cook, the extinguisher, and an alarmclock for setting the extinguisher in motion. Figs. 2 and 3 are respectively a sectional side elevation and a rear elevation of the extinguisher.

In the drawings, X represents an ordinary alarni-clock-as an Ansonia clock, for example.

Y represents the extinguisher as a whole, and Z represents the gaseock.

Referring to Figs. 2 and 3, I will describe the simple spring-motor device, which I call the extinguisher. a a a represent the parts of a suitable frame, in which is mounted an arbor or shaft, 1), which is driven by an ordinary clock or watch spring, a, in the usual way with the mechanism of spring-clocks. On this arbor is ratcheted atoothed wheel, (I. By ratcheted I mean that when thiswheel is held fast the arbor may be rotated, in order to wind up the spring 0, a pawl, e, on the wheel engaging the teeth of a ratchet-wheel, e, carried by the spring-arbor b. A spring pawl or dog, f, engages the teeth ofwheel d to form a detent, and this dog is connected by a cord,

9, or the like with the vibrating hammer it (see Fig. 1) of the alarm-clock X. On the spring-arbor b is secured a sheave or drum, 'i, on which is wound a cord, j, or the like, the other end of which is attached to the lever-arm or thumb-piece k of the gas cook Z.

The extinguisher Y may be mounted and arranged in any convenient manner with respect to the gascock and alarm-clock. In Fig. l I have shown it. attached to the chandelier or drop-light and near the gas-cock.

In winding up the extinguisher the operator unwinds cordj from sheave i. Then when the gas is turned on the slack in the cord is taken up,or nearly so. \Vhen the alarm sounds, the vibrating hammer It draws the dog or detent font of engagement with the teeth of wheel (I, thus releasing it, and this allows the spring 0 to rotate arbor b and the sheave t thereon, and thus wind up cord j and shut off the gas. The cord j might wind directly on the arbor b; but when it winds on a sheave on the arbor a less number of turns is required to wind up the necessary length of cord. The spring may bcwound up by means of an'ordinary thumbpiece, Z, on the end of arbor b.

Having thus described my invention, I claim- 1. An automatic gas-extinguishing apparatus comprising an alarm-clock with a vibrating hammer, an extinguisher, as Y, comprising a spring-arbor and spring, a detent connected to the vibrating hammer of the clock, whereby the movement of said hammer releases said detent, and a cord or the like connecting said spring-arbor with the arm of the gas-coclgwhereby when said detent is released the spring winds up said cord and shuts off the gas.

2. The combination to form an extinguisher, Y, of a rotatively-mounted spring-arbor, b, a spring, a, to drive said arbor,a toothed wheel, cl, ratcheted on said arbor, a detent, f, engaging said wheel, its cord or connector 9, the sheave i, and the cord or connectorj, wound thereon, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
