MEANS FOR LIGHTING AND EXTINGUISI-IING GAS-LAMPS.

To all whom 'it may concern:

Be it known that I, AMEDEO GIoReI, a subject of the King of Italy, residing at Florence, in the Kingdom of Italy, have invented new and useful Means for Lighting and Extinguishing Gas-Lamps, of which the following is a specification.

My invention relates to means for lighting and extinguishing gas lamps, and it consists of an arrangement of valve wherein a ball, which closes the gas passage to the burner, is designed to be moved from its open or closed position by a striker when force is applied thereto outside the apparatus, while at the same time the striker opens a passage for the gas to a suitable flash-lighting device, which passage remains open only while the pressure on the striker continues.

In the accompanying drawings: Figure 1 is a vertical section of an apparatus constructed according to my invention, for lighting and extinguishing gas lamps. Fig. 2 is a vertical section of the casing of the apparatus, showing more particularly the seats for the ball. Fig. 3 is a sectional view of the tube which forms the passage to the flash lighting device. Fig. 4 is a plan of the casing and striker. Fig. 5 is a view similar to Fig. 1, showing the ball midway in its travel between the two seats, after being struck.

In carrying out the invention, a casing a, is adapted to be screwed, at 64 on the gas service pipe and the cover a of the casing, to receive the burner fitting. On the floor of the casing a, are two seats I), 0, the seat 5 being in direct communication with the gas supply, while the other seat 0 has no communication whatever, the ball m, of necessity always resting on one or other of the two seats. In the side of the casing a, is screwed a short tube cl, in which works a push-rod e carrying the striker 7'", which is so formed that it will move the ball 07;. from either seat to the other. The inner end of the push-rod 6 forms a valve at 6 whereby gas is admitted into the tube d, so long as pressure is applied to the push-rod e, the said tube being in communication, through the hole Z, with the flash-lighting device. The outer end of the push-rod e carries a ring, or piston, g, which slides inside the tube d, and serves to prevent the escape of gas and to compress the controlling spring h which tends to keep the valve closed.

Specification of Letters Patent. Patented July 19, 1910,

Application filed January 21, 1910.

Serial No. 539,346.

The operation is as follows :Supposing the'ball m to be located in seat I) so as to close the passage to the gas supply, if the push-rod e be struck, the ball will be knocked ofi its seat 5 on to the other seat 0, and gas will pass through the cover a to the burner. At the same time, so long as pressure is applied to the push-rod e, the gas will pass to the lighting device through the tube d, which communicates therewith. When it is required to extinguish the light, the striker f must be again operated, when the ball no will be knocked back on to the seat 7) communicating with the gas supply.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In means for lighting and extinguishing gas lamps, the combination of a casing adapted for connection to the gas supply pipe and having its floor provided with a pair of seats one of which has communication with said pipe; a valve adapted for reception in said seats; a striker arranged within the casing for shifting the valve from either seat to the other; and means for operating said striker.

2. In means for lighting and extinguishing gas lamps, the combination of a casing adapted for connection to the gas supply pipe and having its floor provided with a pair of seats, one of which has communication with said pipe; a ball adapted for reception in said seats; a striker arranged for movement into contact with the ball, said striker having its ends curved for shifting said ball from either seat to the other; and means for operating said striker.

3. In means for lighting and extinguishing gas lamps, the combination of a casing adapted for connection to the gas supply pipe and having a seat in its floor in com munication with said pipe; a valve adapted for reception in said seat; a tube connected to the casing and in communication with the interior of the latter and with a flash-lighting device; a striker arranged within said casing for removing said valve from said seat; and an operating member connected to said striker and slidable in said tube, said member having its inner end constituting a valve, whereby gas is admitted through said tube to said flash-lighting device when said member is moved inwardly of said tube.

4. In means for lighting and extinguish ing gas lamps, a tube in communication the tube, substantiallyes and for the pur- 0 With the flash-lighting device adapted to be pose set forth.
