ELECTRIC GAS LIGHTER AND EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 379,396, dated March 13, 1888.

Application filed July 2, 1887. Serial No. 243,263. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE L. HOGAN, of Olmstead, in the county of Logan and State of 1 Kentucky, have invented a new and Improved I 5 Electric Gas Lighter and Extinguisher, of

which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which Figure 1 is a side elevation, partly in section, of my improved gas-lighter. Fig. 2 is a rear View, partly in section. Fig. 3 is a horizontal section taken on line 00min Fig. 1. Fig. 4 is a vertical section of the gas burner and valve. Fig. 5 is a detail plan view of the conr5 taet-springs, and Fig. 6 is a diagram showing the electrical connections.

Similar letters of reference indicate corresponding parts in all the figures.

The object of my invention is to provide a simple and effective device for turning on gas at a distant point, lighting it, and turning it off through the agency of an electric current, the device to be used for lighting a singlelanip or a series of lamps at the same instant and to 2 5 be used for street or oflice lighting.

My invention consists in a gas-burner provided with a pnppet-valve operated by ashaft and eccentric receiving rotary motion from the oscillating armature of an electro-magnet,

0 the mechanism being adapted to alternately open and close the gas-supply passage.

It also consists in the combination,with the ratchetwheel secured to the valve-operating shaft, of two pins projecting from opposite 5 sides of the wheel at right angles at diametrically-opposite points and a pair of contactsprings arranged to be operated in alternation by the said pins for breaking the opening and closing circuits when the valve is opened or 0 closed.

My invention also consists in the combination, with the valve and circuit operating mechanism, of a pair of conductors carrying a platinum coil pivoted to the gas-valve casing 5 and acted upon byacam carried by the ratchet wheel, so as to push the platinum coilupward into the vicinity of the burner--tip, and at the same time to bring thelower end of one of the conductors against the contact-spring for completing the circuit.

To the base A is secured a cylindrical casing, B, terminating in aburner, O. Thelower end of the base A is adapted to receivethe gassnpply pipe, and the gas-passage a, extending through the base, is enlarged near the top of i the base, forming a valve-chamber, b, which is partly closed by the plate a, forming the valveseat. To the plate 0 is secured an arm, (I, which is apertured vertically, forming a guide for the stem e of the valve D. The valve D is smaller in diameter than the valve-chamber b, and is adapted to close the opening in the plate 0. The upper end of the valve-stem 6, above the arm d,is secured toafiatspring, f, attached to the side of the wall of the casing B and provided with a shoe, 9.

On a shaft, E, extending through the casing 13, is secured an eccentric, F. The eccentric F is arranged to engage the shoe 9 on the spring f, so that when the shaft E is turned, in the manner presently to be described, it car ries the eccentric F around and presses downward the spring f, thus opening the valve D, and the further turning of the eccentric releases the spring f and allows it to close the valve D. Both ends of the shaft E are prolonged beyond the side of the casing, and upon one end of the shaft is secured the ratchetwheel G.

Upon the extremities of the shaftEare pivoted the arms h i, which carry the armature H and form the armature-lever. These arms swing loosely upon the ends of the shaft E. To the inner side of the arm 2' is secured a ratchet-wheel, I, whose teeth are oppositely inclined with respect to the teeth of the wheel G. To the ratchet-wheel Gis pivoted a pawl, j, which is pressed into engagement with the ratchet-wheel I by the spring is, secured to the wheel G, and upon the flattened surface of the casing Bis pivoted a pawl, Z, which engages the teeth of the ratchet-wheel G, the said pawl Z being pressed into engagement with the.

ratchet-wheel by a spring, m. The armature H is maintained in its normal position by a spring, a, attached to the casing 13 and connected with the arm 73.

To the lower part of the base A is secured a plate, J, which supports an electro-magnet, K, underneath the armature H. To an arm,

0, projecting from the side of the casing opposite the armature H, is journalcd a rock-shaft, p, carrying at one end an arm, g, which engages a cam. r, carried by the ratchet-wheel G, and is furnished at its opposite end with an arm, 8, carrying an insulating-bar, t, to'which are attached two conductors, to o. The con ductor u is prolonged below the insulating bar t, and both of the bars a r extend upward parallel with each other to a point opposite the burner C. The upper ends of the conductors a v are connected by a platinum spiral, w. A flat contactspring, L, secured to the plate J, extends upward into the path of the prolongation ct of the arm a.

In the outer face of the ratchet-wheel G is inserted a pin, 1), at right angles to the face of the wheel, and at a diametrically-opposite point is inserted a similar pin, 0', in the inner face of the ratchet-wheel G, and to. the plate J are secured two contact-springs, d e, which project upward into the paths of the pins bc. Opposite the springs d c is supported a post, f, by the plate J, the said post carrying two contact-points,hi, which normally are touched by the springs d c. To the plate J are attached bindingposts M, M, and N.

The mechanism described is inclosed by a cover, 0, fitted to the plate J and provided with an aperture, j, through which the parallel conductors to '0 project.

The electrical connections are as follows: The binding'post N is connected with the wire 7t, leading to the conductor 1;, and with one terminal of the magnet K by the wire Z. The remaining terminal of the magnet K is con nected with the postf. lhebinding-post M is connected with the spring (1, and the hinding-post M is connected electrically with the springs L c by the wires on a. At the central station is arranged a switch, 1 provided with the contact-points op. the binding-posts q r, and the switch-lever s. The binding posts q r are connected with the terminals of the battery Q. The binding post q is connected with the pivot of the switclrlever s. The bindingpost 1' ol' the switch is connected by a wire, 6, with the binding-post N of the distant lamp. The contactpoint p of the switch is connected by a wire, a, with the bindingpost M, and the contact-point 0 is connected by a wire, 2), with the binding-post M of the distant lamp.

The operation ol'my improved device is as follows: When it is desired to light the lamp, the circuit is closed by pressing the switclrlever s on the contact 0, when the electric circuit is alternately opened and closed by the key It, placed in the circuit, thereby causing the armature H to be alternately attracted and released by the magnet K. Each douuiward movement of the armature H causes the ratclr et-wheel I to turn on the shalt E and by its engagement with the pawl j to move forward the ratchet-wheel Gone tooth and each upward movement of the said armature H (due to the attraction of the spring 91.) turns the ratchet wheel I in the opposite direction, bringing a new tooth into engagement with the pawlj. The next downward movement of the armature carries forward the ratchet-wheel G another tooth, and so on as long as the circuit is complete. During the step-by-step movement of the ratchet-wheel G the cam 'r is brought into engagement. with the arm (1 and the prolongation a of the conductor a is broughtinto engagement with the spring L, causing a part of the current to flow through the said conductor and through the platinum wire 20, thereby heating the wire. The motion is thus continued until the turning of the eccentric has opened the valve I) and the for ward movement of the cam 1- has carried forward the platinum coil w,bringing it into contact with the escaping gas and igniting it, the said earn 0' afterward releasing the arm q, allowing the conductors to '0 to be carried away from the burner by the action of the spring L, until, finally, the pin b comes into engagement with the spring 0, breaking the circuit between the said spring and the contactpoint t, projecting from the postj. When this occurs, the further operation of the magnet through the wire 2; is prevented and the valve D remains open, allowing the gas to escape through the burner until it is desired to shut off the gas.

The shutting ofii of the gas and the extinguishingjof the light are accomplished by placing the switch-arm s on the contact-pointy, then making and breaking the circuit by means of the key It, the current flowing through the wire a, binding post M, spring (1, contactpoint It, post f, magnet K, wire Z, bindingpost N, wire t, and binding-post back to the battery Q. Eachimpulse of the current causes the magnet K to attract the armature H and move the ratchet-wheel G and its shaft by a stepby-step movement until the eccentricF has attained a diametrically-opposite position, thereby allowing the valve 1) to close, as shown in dotted lines in Fig. at. Assoon as the valve is closed, the further movement of the ratchetwheelG brings the pin 0 into contact with the spring (1, thereby breaking the circuit and preventing the further movement of the shaft E and eccentric F until it is desired to again turn on and light the gas.

\Vhen applied to street or series lamp lighting, the burner is to be fastened onto the gassupply pipe. The office-connection of the wires is made as above specified. These wires are then passed through the like bindingposts of each burner throughout the whole system. Thus when one lamp is lighted the whole series will be lighted.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In an electric gas-lighting apparatus, the combination, with a burner and a springpressed valve therein, of an electro-magnet, an armature supported in the field of the magnet, an eccentric for depressing the valve against the action of the spring,and intermediate mechanism for operating the eccentric from the armature, substantially as described.
