To allwhom'tmay cimcem:` j f Beit known'that I,'Pnrnn A. J onANsnN, a citizen of the United States, residin `lat Omaha, in thecounty of Douglasand tate of Nebraska, haveinvented certain new 'and useful Improvements in (Blas-Range Lighters, of which the followingis aspeeicatlon.

This invention has reference` to automatic means for lighting gas ranges electrically, at

`the time of turning on the as. y l The object of the inventlonjis ,to rovide an inexpensive device, Yoperatedby e ectricity, which may be attached to anyordinary which will consist of few `parts and -Willbere gas range, and by means of which. the burner oll the range may be automatically lighted,

liableinoperation. f An ther object is the provision'lof devices which, when operated, will cause the `flame to be thrown a 'considerable'distanca com- Earatively, from` the igniting devices, `for 'ghting the burner, l"for the purpose of `pre-J venting decarbonization of parts., f f Another object is the provisionr of devices for causing the ignition `ilame to .be thrown upon the same horizontal plane as,` that ofthe burner; and a further Objectis the provision of .ignition devices Whichare `located out ofl the pathway 'of the ignitingilame, topreventdecarbonization, and the use of devlces for Vautomatically .lighting the vgas range, which .may be inexpensively replaced :when worn or injured.

'The in,vention consists fof the combination and arrangement of parts herein described, pointed out by the claims and illustrated by the drawing, wherein,- .f-

. I provide the valve-housing) 15 or ischarge-pipe 10,` as-co/ck 16 eing seated therein, and asthus described the discharge-` pipe is disposed adjacent supply-pi e 2 a convenient distance yfor mounting t ereon lained and transverse portion12 may be isposed closely adjacent pipe'1, as shown, that there may be adequate space for operatively securing upon theterminalofthe discharge-pi e certain sparking devices, without encroac g u on t e space occupied bytheburn'er;` an as thus constructe nozzle or terminal 17 of the ,dischargeipe is disposed. upon the horizontal laneo the burner.v

igidly upontheupper end of gas cock 8 is mounted pinion 18, and upon the upper '18., vis secured` pinion 19. 1 ounted rigidly upon ygas-,co cl16, land havingl a center coinycident therewith,is barrel or cylinder 20; :and upon portion 13 of the discharge pipe'is ;m'oun`te'd 4guide 21, yWithin which is seated `shaft or sparking-rod 22 having a transversely formed arm 23 upon its free end, the

mountl asat'24 in thejdirection indicated by its arrow, will cause acorresponding rotatable movement of pin1on18l to cause a revoluble movement :off pinionv 19' in thedirectionofits arrow,

therebyfcausin'grod22 to .have a limited rearwardmovement, saidvmovement of the handle alsocausing a revoluble movement of both gas-cocks.

.end of gas cock-16, and vin ear with pinion Near the free end o-fp-ortion 13 ofthe disa stationary insulated mountin u 10 supply-pipe 2 an charge pi e is seated insulating-ring 25, and secured t ereon is the metal ring. 26, and upon this metal ring is mountedthe metal ost 27 which extends outwardly somewhat rther than nozzle 1,7, and upon post 27 is vsecured the metalffinger 28, preferably bent to form the transverse contact-blade 29; and `as thus described, contact-blade 29 has on and isdisposed adjacent the termina o 4 the dischargeipe. Contact-blade 29 may be constructe of anyresilient metal and is disposed in the ath traversed vby contact-arm-. 23 during the engthwise movement of 4rod 22 so that a contact of these metal parts wilh yrectlon of its arrow 90 degrees, gas-cock 8 will be open, and this movement will actuate inion 19 and, thereby, open valve 16 to alow gas to pass through the discharge pipe and nozzle 17; at the time of this movement arm 23 will make contact with and will pass Y It will be noted that the metal blade 29 since sparking-rod 22 will have a rearward movement. ,Any electrical Tneans is employed, as battery 30, to energize wires 31 and 32, and spark-coil 33 is employed;

lwire 31 may have a metallic connection as at 34 upon thevalve-housing 15 so that arm 23 of rod 22 will be energized with electricity of one sign, and wire 32 will energize blade 29 with electricity of the opposite4 sign, and at the time gas is passingl nozzle 17, a spark is created by arm 23 tripping upon blade 29, already explained, which ignites burner '3.

parts which coperate to produce the spark are located at a considerable distance from burner 3 and this 'is desired so that decarbonization of these parts may be prevented. Cooking vessels, when placed upon the'burner, cause lthe burning gas to flare outwardly from the burner, and in order-that the metal devices j may not be injured by the heat, they are disposed as shown, 'and an ignition iiame is thrown, in thepresent instance, from a safe distance upon the plane of the burner, and

these devices and their arrangementl will now be explained.

Nozzle 17 is provided with an oriiice 35 of less diameter than any part of the bore 36 -of the discharge pipe, and onthis account,

at the time of opening the valves as described, gas is driven from the nozzle with considerable force at the time the spark is created, so that a flame of adequate length passes from thenozzle to reach and to reliably ignite the gas of the burner. It will be noted that arm 23 and blade 29 are located near, but not at the front of orifice 32, and thereby these parts are not obtrusive to prevent a free flow of the gas at'the time the atteris forced out of the orice; also the possibility of decarbonization of these metal partsis minimized by reason of this location since they are not in the pathway of the forwardly forced stream of flame coming from V the nozzle when the valves are open.

It will be understood by those conversant with the operation of as cocks, that gas will pass before the valve as rotated the entire 90,` degrees, and in the resent instance gas reaches burner 3 before Eandle 9 has been rotated the 90 degrees mentioned. Since pinion 19 upon the discharge pipe has a less diameter than pinion 18, its revoluble movement, when actuated, is greater than that of pinion 18; gas-cock 16, therefore, during operation, rotates more rapid and allows passage of gas sooner than does gas-cock 8.

It will be understood,v therefore, that gas will' pass the discharge-pipe before handle 9 has moved the full 9() degrees; during this movement contact-arm 23 engages blade 29 and bends the latter inwardly, since rod 22 has a lengthwise movement from the artial rotation of c linder 20; as soon, owever, as blade 29 1s tripped or released from arm 23 the spark is made, and at this moment gas has passed both valves, so that the burner is lighted; when the handle has been moved 90 degrees, as described, gas is freely communicated to the burner through the supply-pipe, but at this time valve 16 of the dischar epipe is closed, this closure being effected y reason of the difference in diameters mentioned of pinions 18 and 19.

Pinion 18 is provided with blanks 37 and 38 upon its periphery which operate as stoplugs to contact with the teeth of pinion 19, to limit the movement of the gas-cocks and handle 9, and thereby prevent the turning on ofgas by use of the handle except in the manner described.

If, for any reason, blade 29 or arm 23 should become injured or worn, they may be replaced at slight expense, as they are se arate parts and are conveniently mountedp in a manner to be readily removed or replaced.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is,-

combination with a gas supply-pipe having a gascock with a pinion thereon, of a discharge pipe in communication with said supply-pipe and having a gas-cock with a pinion registering wi th the inion of the supplyipe gas-cock; an insu ated metal contact-b ade 1.
