ELECTRIC GAS-LlGHTlNG DEVICE.

SPECIFICATION forming part of Letters Patent No. 571,288, dated November 10, 1896.

Application filed August 1,1896. Serial No. 601,351. No model.)

Be it known that I, ERNEST SCHMIDT, a subject of the King of Prussia, German hmperor, and a resident of Berlin, in the Kingdom of Prussia, German Empire, have in vented a certain new and useful Improved Device for Lighting Gas and other Lamps, of which the following is a full, clear and exact description.

The present invention relates to devices for lighting gas and other lamps automatically by means of electricity; and it consists of the details of construction hereinafter set forth, and particularly pointed out in the claims; and in order to render the present specification more easily intelligible reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views.

Figure 1 is a front elevation of the lower part of an incandescent gas-burner, showing the igniting device with the cap or casing of the same in section. Fig. 2 is a side elevation of Fig. 1, the cap being in section. Fig. 3 is a detail side elevation showing the operation of the mechanism for turning the gascock on and off, the mechanism being in the position it occupies when the cock has just been turned on. Fig. at is a similar detail elevation showing the double pawl in the act of engaging the opposite pin of the gas-cock to turn the gas oif on the next movement of the armature controlling the said pawl. Fig.

5 is a similar elevation showing the armature attracted by the electromagnet and the cock turned off. Fig. 6 is a detail sectional elevation of the cock employed in connection with the present device; and Fig. 7, a horizontal section through the burner-tube, taken just above the armature-pivot and showing the double armature in plan view.

According to the present invention the whole igniting mechanism,with the exception of the battery, is mounted on a base-plate A, arranged at the lower part of the burnertube, and a partially-rotating disk R is employed to turn the gas on and off, although any other suitable cock might be used without departing from the nature of the present invention. This disk may be seen in section at Fig. 6 and is provided with depressions a: and p on its facing and with acentral bridgepiece n", dividing the said depressions, while the gas-tube is provided with a lateral facing, on which the disk turns on a pivot, said tube having a partition ll, so that the gas can only pass to the burner along the channel ll through the depressions and y, and when the disk is turned so that the bridge 20 corresponds with the partition end the gas supply will be cut off. he disk R is pivoted at a to the partition and provided wit-h two substantially diametrically oppositely arranged pins to and I), over which the double pawl K, which is actuated by the electromagnet A, can engage alternately, and exercising a pull 011 same opens or closes the cook. The cock is provided with a downwardly-extendin g tail g, which passes through a slot in the baseplate A, the ends of said slot forming stops for the movement of the disk R, as will be seen from Fig. 1.

Attached to the center of the disk R is a spring c,which engages the arm of the double pawl K in the following manner: The double pawl K is loosely suspended from the proj ecting arm of a double armature,hereinafter to be described. hen the armature is attracted, the pawl is raised, and when the same is released the pawl sinks to its lowest position. The object of the spring 0 is to throw the pawl K or its corresponding hook under the hooks or pins a and b of the disk R alternately. Thus, for instance, supposing the two pins a and l) to be in the horizontal plane opposite each other and the cock neither closed nor fully open, then the spring 0 will exercise no pressure on the rod of the pawl. If new the cock is fully opened by the action of the armature, as shown at Fig. 3, then the spring will have been turned by the movement of the disk R, to which it is attached, and will exercise pressure on the pawl-rod, tending to push it to the right of Fig. 3. As soon now as the armature has been released the pawl will fall and the action of the spring 0 will throw it under the pin l), as shown at Fig. l. On the next movement of the armature the pawl will pull the disk round in the opposite direction by means of the pin Z) and close the cock, simultaneously turning the spring in the opposite direction, so that on the next release of the armature the pawl on falling will be thrown under the pin a ready to turn the cock in the opposite direction at the next movement of the armature.

The electromagnet A is mounted on the base-plate A, and a double armature B O is pivotally supported on pivots l3 l3, fixed in the sides of the burner-tube. The arrangement of the armatures B C will be best seen from Figs. 1, 2, and 7. Both armatures are arranged to turn on the same pivots, as clearly shown at Fig. 7, and the lower armature B is provided with a counterpoise G, which pulls it away from the magnet when the latter is not excited. The upper armature C passes through a recess in the lower one B at a point above the electromagnet and is capable of vibration on its pivots without influencing the armature B, for a reason hereinafter stated. The lower armature B is extended round behind the burner-tube, looking from the magnet side of the same, and carries at this side the double pawl K,whieh is loosely suspended therefrom, so that a movement of the lower armature B will opcrate the pawl K. The upper part 0 of the armature when attracted will close a spark generating electric circuit by means of tubular rods Z and Z. The outer rod Z is fast on a plate M on the burner-tube, and the inner tube Z is insulated and vertically guided to slide within the tube Z, the upper ends of the said tubes being formed to produce electric sparks when the armature is attracted. The inner tube Z is normally held down,with its upper bent round end, Fig. 2, resting on the upper end of the tube Z, by means of an insulated spring on, mounted on the under side of the plate M and acting on the lower end of the tube Z to keep the same down on the tube Z. The lower end of the inner tube Z is connected by a small tube 0 to the gascoek, and its upper end isformed to produce a jet-flame, when the cock is opened, which will be ignited by the electric sparks generated at this point.

One pole of the battery is connected to the contact-screw P on the plate A, which is insulated from the gas-tube of the burner, and the other pole is connected to the burner-tube.

The end F of the upper armature (J is formed to engage under the end of the rod Z when this armature is attracted and push the same slightly upward, so that electric sparks will be formed at the upper end of the tubes Z Z.

\Vhen the current is sent through the apparatus, both the armatures will be attracted, one, B, opening the gas-cock in the manner already described, and the other, C, slightly raising the jet-flame tube Z against the pressure of its spring m, so that gas will be fed to this tube through a, and at the same time sparks will be generated at the upper ends of Z and Zand the jet-flame lighted. On turning oii' the current the armature will be released and the pawl will. fall down ready to engage the opposite pin of the disk R at the next attraction of the armature. and operate the cock in the opposite direction. The object of making the armature in two parts 1; and C is that when sparks are produced at the upper ends of Z Z by the contact of the end F of the lever C with the lower end of Z the latter is liable to vibrate, and were the armature in one piece this vibration would be liable to be communicated to the cock and cause the same to be turned partially back, possibly before the gas may have been lighted. In the present case the part 0 of the armature is free to vibrate and cannot communicate its vibration to the part B, which remains in position on the electromagnet as long as the same is excited.

Instead of arranging a jet-flame it is obvious that the electric sparks may be employed to ignite the gas direct without first igniting the jet, but the latter is preferable in connection with incandescent gas-lamps.

I claim as my invention- 1. An apparatus for automatically igniting gas and other lamps by means of electric current which consists of an electromagnct having an armature consisting of two independently-movable members, a gas-cock operatively connected to one member and an igniting device operatively connected to the other member, and means for sending one and the same current through the electromagneteoils and to the spark-producing device sub stantially as described.
