IMPROVEMENT IN ELECTRIC LIGHTING ATTACHMENTS T0 GAS-BURNERS.

Specilication forming part of Letters Patent No. l 52,427, dated June 23, 1574; application filed March 19, 1374.

To all allem. it may concern:

Re it known that I, ADOLPH T. SMITH, ot' thc city, county, and State otNewYo1lz,lia.xe invented a new and uselul Improvement in Electro-Magnetic Gas-Burners 5 and I do hercby declare the -following to be a full, clear, and exact description thereof, which will ena ble those skilled in the art to make and use the same, reference being had to the accompanying drawinguformiug part of this specification, in which drawingliigure l represents a side View oi" this invent-ion. Fig. 2 is a plan or top Yiew ot' the same.

Similar letters indicate corresponding parts.

rThis invention relates to a gas-burner the body of which forms the core of a helix, one end et' which is in metallic contact with the armature ot' the electro magnet, while its other end Ais in. metallic contact with a spring that acts on a camsecured to the plug of the gas-cock, in such a manner that, while the cock is being opened, the armature ol" the elcctro-magnet receives a vibrating motion, producing a number of sparks, which light the escaping l'rom the tip.

ln the drawing, the letter A designates a gas-Inliner, which is secured in a pipe, '13, that can be opened or closed by means oli' a stopcocli, C. The bod y of said burner is made ot' soft iron, and on it is secured a helix, D, which is insulated from the burner or core A, and one end ot which connects with a springlever, E, that carries the arn'lature l", while the other end ot' said helixconnects with a switch-swing, G, which is secured to the gaspipe B, but insulated from. the same.

.From the armature-lever E extends a wire, n., the end of which bears against the end ot another wire., I), that is iirinly secured to thc burner A, and is in metallic contact with the ground through the gas-pipes themselves.

On the plug of the stop-cock G is secured a cam, Il, which is composed ot' an insulating base-plate, c, and a metallic top plate, d, so that the metallic top plate is insulated from the plug. From said top plate extends a wire to one pole ot' a battery, the other pole ot' which connects with the ground.

The cam Hf consists of two segmental wings, c c, which arc inclined, as shown in Fig. l, and which are separated from each other at their high ends by a reeess,j", Fig.

VWhen the stopcocl; C is open, this recess is over the tip ot' the switch-spring G, and as the cock is being closed said tip slides at the under surface ot' one of the wings c until it passes the low end of the wing, when it (the tip) flies up by its inherent elasticity.

When the cock is being opened, the tip of the switch-spring G slides up on the metallic surface of one et" the springs e, and as soon as the switch-spring comes in metallic contact with the cam H, the circuit is closed from the battery through the plate d of cani Il; thence through switch-spring G to helix D, through this helix to armature-lever D; thence through wires ay b, burner A, and pipe B to the ground, and through the ground back to the second pole ot' the battery.

As the circuit is closed, the armature F is attracted by the core A 5 the wire e is thrown out ot' contact with the wire b,- thc circuit is broken; the wire e i'alls back against the wire b; the circuit is again closed, and so on as long as the contact between the switch-spring (lv and the metallic suiiface ot the cam H lasts, and each time the wire e talls back from the wire b an elastic spark is produced, so that as soon as begins to escape from the tip of the burner A, it will be ignited without fail.

The cam Il is made with two wings, c c, so that the switch-spring G must come in contact with one of said wings, in whatever direction the plug ofthe stoplcocl; is turned. Said plug is supposed to be so constructed that it can nia-ke halt a. turn, or that, when it has been opened, it can be closed either' by turning it to the right or to the lett, but it' the plug has only a quarter-turn, and consequently must be opened and closed always in the same direction, one of the wings ot' the cani H becomes supertiuous.

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

l. The helix l), arranged on the body of a gas-burner, said bodv being made to forni the core of the helix, in combination with the ar= mature F, und contact-peints (L b, und :u1 elee- I 3. The cum H5 provided with two wings, 6,
