To all whom it may conce-m: A

13e 1t known that l, HENRY JAMESON, a

citizen of the United States of America, re-

siding atdoplin, in the county of Jasper and `:State ot Missouri, have invented new and useful Improvements in Electric Gas-Igniting Devices, of which the following is a specification.

rThis invention relates to gas igniting devices adapted for use in connection with gas stoves, gas lighting burners, explosive en gines and the like.

The invention has for one of its objects to improve and simplify the construction and operation of apparatus of this character so as to be comparatively simple and inexpensive to manufacture, and reliable and efficient in use.

Another object ot the invention is the provision ot a jump spark vignition system in which the primary and secondary circuits are normally open and are adapted to be simultaneously closed by electro-magnetic ally-operated switches, the circuits of which are closed when the system is to be thrown into use.

With these objects in view, and others as will appear as the invention proceeds, the invention comprises the various novel eatures of construction and arrangement ot parts which will be more fully described hereinafter and set forth with'particularity in the claims appended hereto.

in the accompanying drawing which illustrates one of the embodiments of the invention r-Figure 1 is a diagrammatic View ozt the system adapted for stovev and lamp lighting. Fig. 2 isa sectional view ot' one of the electro-magnetically-actuated switches. Fi 3 is a side view thereof. Fig. 4 is a'detall view of one of the jump spark igniting devices.

Similar reference characters refer to similar parts throughout thev several views.

Referring to the drawing A designates an illuminating burner of the upright mantle type and B a burner for a gas stove, both burners being provided with a jump spark ignition device C. This ignition device comprises in the present instance a platinum wire or other electrode 1 vwhich has its free end formed into a terminal 2 that is presented to slidably separate from the metal electrode 3. rThe electrode 3 is in the form of a screw that is threaded in an opening 4 in a support 5 of hard rubber or other insulating material, the screw being adjustable toward or away from the terminal of the electrode 1 so as to adjust the spark gap. rilhe electrode 1 is secured to the support-ing piece or base 5- by a bolt 6 that serves as a binding post for connecting the said electrode in the high tension circuit. rlhe screw 3 is so arranged as to connect the base plate 5 of the sparking device to the burner.

rEhe burner A has a pilot tube 7 that passes through the screw 3 and the spark ignites the gas passing through this tube so that the dame will ignite the gas issuing through the mantle. In the case of the burner B the screw 3 is secured in one of the jet apertures 8 in the top plate of the burner so that the gas issuing through the screw will be ignited by the spark produced by the device C.

The current for the primary circuit is derived from a battery l) or other suitable source and one side of the battery is connected by a wire 5) to the primary winding of a vibrating coil E. Between the other terminal of the coil and battery are wires 10 and 11 which are adapted to be connected by an electro-magnetically-actuated switch designated generally by l?. The secondary i circuit consists of a wire 12 connected 'wit one terminal of the secondary winding of the coil n nd which divides into two branches 13 and 14 that lead to the electrodes 1 of the sparking devices C While the other terminal of the secondary winding is connected to ground at 15 by the wire 1G. ln the wires 13 and 14 are electromagneticallyactuated switches G. rlhe electrodes E of the sparking' device are electrically connected with 'the burners which are in turnconnected to ground so as to complete thesecondary circuit.

Each electromagnet comprises a core 17 of soft iron or other magnetic material on which is wound the coil 18 which is inclosed in a casing 19, there being a cover 2O of insulating material through which the polar extremity 21 of the core extends. Attached to the casing and'disposed over the core is an amature 22 which has sui'iicient resiliency to be normally separated from the core and on the armature 1s a strip of insulation 23 which, in the present case of the switch F, carries a contact 23and isadapted to engage with a stationary contact 25 on the .plate of insulation 20. The wire 10 of the primary circuit connects with the contact 25 while the wire 11 connects with the contact 24 and when the electro-magnet is energized the contacts will be brought together so as to complete the primary circuit. The windings ot the coil 18 of the switch F are connected with binding posts 26 and 27 Fig. l, the former of which is connected by a wire 30 with a battery 3l that in turn is connected y to ground byl the wire 32. The switches G for controlling the secondary or high tension circuit are each provided with'spaced contacts 33 and 34; with which the wires 13 and 14 are connected and the armature carries a bridging metal piece 35 that is adapted to engage both contacts 33 and 24: so as to complete the circuitthrough either wire 13 or 14. The windings of the coils oi the switches Gr are coimected with the binding posts 36 and 3T and these coils are connected in series with the coil of the switch F by the branch wires 3&5 that connect with the binding posts 3G Iwhile the binding' posts 3T are connected by wires 39 with the burners or gas pipes which are themselves grounded, there being included in the wires 39 push buttons l() whereby the vcontrolling circuitof the magnetically-actuated switches are manually closed.

lIn lpractice tliesupply of gas to the burner A is turned on by opening the valve at the same time the push button 40 is depressed so as to send a current simultaneously through the coils of the switch F and the switch Gr for the burner A. `By this means the primaryand secondary circuits are simultaneously closed so that an intermittent current will -be produced in the primary winding of the induction coil E, whereupon a high tension intermittent current will be produced in the secondary circuit for creating a succession of sparks across the spark gap between the electrodes 1 and 3 ot the sparking device C to thus insure the lighting of the burner A. When it is desired to ignite the stationary burner B the switch 40 at such burner is closed so as to energize the electro-magnets that control the primary and secondary circuits of the system for producing sparks applied to the burner B. i

From the foregoing description taken in connection with the accompanying drawing the advantages of' the construction and method of operation will be readily apparent to those skilled in the art to which thel invention appertains and while I have described the principle of operation of the invention, together with the apparatus which I now consider'to be lthe best embodiment thereof, I desire to have it understood that the apparatus shown is merely illustrative and that such changes may bemade when desired as are within the scope of the claims.

Having thus described the invention7 what is claimed as new is l. The combination of a jump spark ignition device, a secondary circuit connected therewith, a primary circuit including a source of current, an induction coil in the circuits, normally open switches in both circuits, an electro-magnet for each switc a controlling circuit in which both 'electromagnets are connected, a source of current connected in controlling circuit o the elecl tro-magnets, and a manually actuated switch i'or closing the circuit of the electro-magnets to close the said normally open switches si# multaneously.

2. The combination of a plurality of ump spark ignition devices, a primary circuit, secondary circuits for the said devices, and

-inductively related to the primary circuit,

an electrically actuated switch for closing the primary circuit, an electrically actuated switch for each secondary circuit, and means y for simultaneously-actuating the first mentioned switch for closing the primary. and one of the secondary circuits.

3. A jump spark ignition device comprising anelectrode, a supporting member there-y for,l and a second electrode on the member spaced from the rst electrode and serving 'as means for securing the device in position.

t.l A jump spark ignition'device comprising a supporting piece of insulatingmaterial,l .a spaced electrode mounted thereon, one electrode being in the form of a 'screw serving to attach the device to a support andl having an opening through which gas to be ignited is adapted to issue.

In testimony whereof I afivixmy signature` in presence of two witnesses.

HENRY JAMESON." Witnesses:
