ELECTRIC GAS-LIGHTIN G APPARATUS.

Specification of Letters Patent.

Patented May 31, 1910.-

To all whom it may concern:

Be it known that we, DAVID M. HAR'rronn,

OARLE'DON M. TAYLOR, and .LEWIS S. S'roxn, all citizens of the United States, residing in the city and county of Los Angeles and State of California, have invented new and useful Improvements in Electric Gas-Lighting pparatus, of which the following is a specification.

our invention relates to that class of devices which are devised especially for lighting gas by means of a jump spark, and reburners-or lamps on vehicles provided with aportable gas system, such as automobiles, railway cars and the like, wherein the whole vehicle is subjected to more or less vibration.

In many electric gas lighting systems,

commonly in use, the gas is turned on automatically by means of solenoids or other contrlvances, which are more or less cumbersome, delicate in operation, and very necessitating the prone to get out of order. In all attempts to apply these systems to automobiles, or other vehicles, which are subjected to vibration, it has been found that the apparatus soon becomes deranged and fails to operate, etting out of the vehicle and lighting the damps by hand, which is often ver inconvenient, especially in a storm, an subjects the operator to much annoyance.

It is one of the objects of our invention to overcome this objectionable feature.

Another object of our invention is to provide a burner base of fibrous or other nonconducting material, provided with adjustable contact points, which will be capable of ap lication to standard burner connections. till another object of our invention is to provide a system of pinng and valve control therefor, which wi l e adapted to be mounted upon the cabinet containing the switch mechanism, so that the'control of the gas ,can be readily made by the OJBIiLtOX simultaneously with the lighting t ereof,

and without his having to leave his position in the car.

Yet another object of our invention is to provide the piping mechanism and its control on the cabinet with shunts or by-passes so that should one or more lamps be placed out of commission, the gas supply thereto can be cut oil while still retaining the other, lamp, or lamps, in service. lVe accomplish these objects by means 0 the device described herein and shown in .the accompanying drawings, in which: Figure 1 represents a front elevation of our lighting cabinet with parts broken away to show the gas pipe connections. Fig. 2 is a section on the line 2-2 of Fig. llooking in the direction of the arrow. Fig. 3 is a detail perspective of our improved s arking device. Fig. 4 is a view of the uner side of our burner,partly broken away to show how the roundin is made. Fig. 5 is a diagram s owing tie battery, switches, coil and burner. Fi 6 is a bottom view of a modified form o bul'nenbase.

Referring now to the drawings more specifically, 10 indicates our im roved cabinet, upon the outer surface 0 which are mounted the switches 11 and 12 which are employed to control the currents flowing from battery 13 and sparking coil 16. The battery 13 is connected with switch 11 by means of wire 14.

15 represents a wire connecting switch 11 with sparking coil 16, while 17 is the return to the battery.

18 indicates a connection from the coil to switch 12, which through switch handle 19 connects with any one of a number of circuits as 20. 21 and 22. As indicated in the diagram shown in Fig. 5, circuit 20 leads to binding post 23 of our improved sparking device and burner support 24.

25 indicates a gas supply pipe, which through a T-eoupling 26, connects with ipe 27 which leads to the main valve 25. rom main valve 28 leads a pipe 29 connecting with regulator valve 30, which in turn coni it nects with a pipe 31 leading to T-coupling 39. From T-coupling 32 the pipe 33 leads to the tee connections 34' supplied with valves 35, which are adapted to cut out the supply of gas to any one ot the pipes :56.

(lur improved sparking, device is equipped with a thread. enabling it to be screwed onto supply pipe 96 and burner tube 39, which bears the tip ll). Our improved sparking device equipped with a binding screw 23 adapted to engage wire 20, and one of the sparking members 4.1, the other sparking' member it connecting through contact 42 i (as shown in Fig. 4-) with supply pipe 36 through the coupling 37, thus grounding the f circuit. l lach oi: the sparking members 41 is provided with slots 13 which enable them i to be adjustably secured to base 38 of our improved burner support it thrmigh the medium at binding; screw 3, contact %2 and 5 rev tl :ety QCUOIIHTEOflfIlIlDg them to burners of ditlcrent sizes. it may be here noted that the base of our improved spark- 1 ing device is formed of tiber or other insulatingmaterial.

in the modification shown in Fig. (3, it" represents a binding post, 48 the sparking f members, 4-9 the groui'iding post, 50 represents fastening bolts, the binding screw, grounding post and fastening screws having i V gen'iei'it with the nuts at which are held in pockets .lt will be t 1 from Figs. and 5, that we provide suita le supporting means 53 for the sparking coil,

in the actual practice of our invention, we have made use oi? the ignition batteries of an automobile, but in magneto machines and wherever desirable, it will be urulerstood 1 batteries Ina be supplied which may be mounted within the cabinet 10, thus making 1 a c inpact; unitary device.

it he operation of our device is as follows: Switch it is thrown to an operative position an tch 1'2- i-anscd to engage with g the contact leading; .o the lamp it; is desired to light. he currer will then flow through E conductor it) to bindingpost. 2 3 up sparking arm ll. jump across to the other sparking arm ll and down same to grounding screw to the coupling 37 and thence to pipe ill) and thus be grounded. in the (HH 1 i an antonwhile the current is grounded in ne iron frame of the machine. Gas is then suppli d through pipe 25, coupling 26, pipe 27, main valve 28, pipe 29, regulator valve 30, pipe 31, coupling 32, pipe 33, tee connec tions .I'll, cut-out valves 35, through burner pipe so to the burner, where it will be ignited by the sparks jumping between sparkinn arms .41.

it will be appreciated by those skil ed in the artto which this invention appertains,

that when the lights are once regulated, by means of the regulator valve 30, that this valve will be left fixed and the gas turned on or oil with valve 28. it will -furthermore be apparent that. should any of the lights be thrown out of service. the valve 2%? in the gas supply pipe leading to that lamp may be closed. thus avoiding the waste ot gzas. Also it will be noted that; through T- coupling Q6 and we have provided means whereby the lighting system may be assembled either right or left; as desired.

The modification disclosed in Fig. 6 may be of especial advantage where it; is desired to form the burner base of porcelain, and also where it is desired to utilize as little space as possible Having described our invention what we claim as new and desire to secure by Letters Patent is:
