GAS-LIGHTER.

Application filed January 8, 1915.

To all whom it may concern Be it known that we, CHARLES FLIEGNER, a subject of the Emperor of Austria-Hungary, and a resident of the borough of the Bronx, county of Bronx, city and State of New York, and SAMUEL HECHLER, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented a certain new and useful Improvement in Gas-Lighters, of which the following is a specification.

Our invention relates to that type of de vices known as self-lighters, wherein the .act

of turning on the gas will strike a spark and ignite the gas at the burner tip.

The objects of our invention are to produce such a device in which the gas will be positively ignited whenever the cock is turned to allow the gas to escape from the burner, and in which the gas can not be turned on and allowed to escape without be ing consumed.

A further object is to produce a device which is economical of manufacture, certain and efficient in operation, and not likely to get out of order.

These and further objects will more fully appear from the following specification and accompanying drawings considered together or separately.

The invention is illustrated in the accompanying drawings, in which the same parts are designated by similar reference characters in all of the figures, and in which Figure 1 is a plan view of our improved fixture, showing the parts in position to cut off the flow of gas. Fig. 2 is a side elevation of the same. Fig. 3 is a sectional view taken on the line indicated by 3-3 on Fig. 1, the parts being shown in position to allow the flow of gas to the burner tip; and Fig. 4: is a side elevation of a modification.

In Figs. 1, 2 and 3 the invention is illus trated in connection with a gas burner in which the cock is at right angles to the burner tip, and in Fig. 4 is shown the manner in which the device may be used in a fixture in which the cock and tip are arranged in the same plane.

In the drawings, 1 represents the fixture which may be screwed to the end of a gas pipe by means of the usual socket 2. A cock plug 3 is mounted to rotate in the usual manner in the barrel 4: of the fixture, and communication between the pipe and the cock plug is permitted through an orifice 5. On the side of the barrel opposite the orifice Specification of Letters Patent.

Patented May so, 1916.

Serial No. 1,157.

5 are two channels 6 and 7 the former connecting the barrel with the interior of the burner tip, and the latter offering communication between the barrel and a recess 8 in the fixture arm. The perforation 9 in the plug is made long enough to span the channels 6 and 7 and allow the gas from the pipe to pass through the orifice 5 and into the channels 6 and 7 when the plug is turned to the proper extent and is so shaped that the channel 7 will be cut off while gas is still flowing through the channel 6. The plug is provided with the usual handle by means of which it may be manipulated.

Rotatably mounted shaft 10, and carried on the shaft, within the recess 8 and in proximity to the channel 7 is a wheel 11 preferably of steel, and having a roughened periphery. Carried on the shaft 10, outside of the fixture, is a segmental pinion 12. The pinion 12 is provided with a shoulder 13 which is adapted to come into contact with a stop 14 on the fixture. The wheel 11 carries a pin 15 on one side thereof, and the pin is engaged by a spring 16 which tends to rotate the wheel 11, shaft 10 and pinion 12 in the Secured to one side of the fixture 1 and extending into the recess 8 over and in proximity to the wheel loosely carried in the socket and resting on the periphery of the wheel is a block 18 of pyrophorous material. The block is held in contact with the wheel by means of a spring 19.

Carried on the plug 3 are two toothed segments 20, 21 adapted to engage the pinion 12 and rotate the latter, and the disk carrying the segments 20, 21 is provided with ratchet teeth 20, 20 21 and 21 The ratchets are adapted to be engaged by a spring pawl 22 to prevent backward movement of the plug 3.

The fixture is provided with a burner tip. 23, of any approved type.

The operation of our improved device is as follows: The parts being in the position shown in Fig. 1, the flow of gas will be cut off and the passage 9 will be at right angles to the channels 5, 6 and 7. On the plug being turned in the clock-wise direction the passage 9 will be moved to connect the channels 6 and 7 with the orifice 5. At the same time the segment 20 will engage the teeth of the pinion 12 and rotate the wheel 11 against the tension of the spring 16. When the last tooth of the segment 20 is in'the fixture is aclock-wise direction.

11 is a socket 17, and

about to leave the pinion the gas will be flowing to the burner through the channel 6 and to the recess 8 through the channel 7. lVhen the last tooth of the segment leaves the pinion the spring 16 will rapidly rotate the wheel 11 under the pyrophorous material, causing a spark which will ignite the gas issuing from the channel 7 and the flame will jump to the burner tip and ignite the gas issuing therefrom. The continued rotation of the plug will cut off the supply of gas to the channel '7 and extinguish the pilot flame while still permitting the flow of gas to the tip. By thistime the ratchet tooth 520* will have been engaged by the pawl 22 and backward movement of the plug will be prevented. WVhen it is desired to extinguish the flame at the tip the plug is rotated in the clock-wise direction to the position shown in Fig. 1, and the pawl will on gage the tooth 21", thereby locking the plug against backward rotation. The segment 21 is now in position toengage the pinion when next it is desired to light the gas. WVhen the pinion is released from the segment and is rotated backward by the spring 16, its movement will be arrested by the engagement of the shoulder 13 with the stop 14, and the pinion will be engaged by the segment 21.

It will be seen that the cock cannot be turned to permit escape of gas without igniting the gas, thereby producing a fixture which will absolutely prevent the escape of unconsumed gas.

While we have shown a pyrophorous material and steel for making the spark, we do not desire to limit ourselves to any particular materials, as two metals or alloys which will produce a spark when brought into frictional engagement may be employed. It is also to be understood that instead of the handle shown for turning the plug, any other device for performing this operation may be used.

In accordance with the provisions of the patent statute, we have described the prin ciple of our invention together with the apparatus which we now consider to represent the best embodiment thereof, but we desire to have it understood that the apparatus shown is merely illustrative, and that the invention can be carried out in other ways without departing from the spirit of our invention.
