ELECTRlC IGNITEFL Specification of Letters Patent.

Patented March 5, 1907.

Application filed August 29, 1906. Serial No. 332.490.

To (Ll/l whom, it ill/(Ly Conner/1 3e it known that 1, JOHN DANIEL VVIL- MOT, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements, in Electric Igniters, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to electric igniters, and mine particularly to a device of the character described especially adapted for pse in igniting gas ranges, stoves, and the .lllif, igniter of the class. described that shallibe siinpl and comparatively inexpensive in construction, durable, and efl'ectual in operalion.

Other objects and ldvantages of the invention, as well the structural features by which such objects are attained, will be apparent from the specification, taken in connection with the accompany ng drawing, in .=;hich

Figure l is a perspective view of the dry batteries and solenoid and a top plan of the sparker or igniter, and 2 a perspective view of the sparker or igniter.

Referring to the drawing, 1 designates two dry batteries, one having a positive and the other a negative pole, which are connected with each other by a kicker-coil 2, one of said batteries being also connected by a kickercoil 3 with a solenoid e. An insulated wire 5 connects the core of the solenoid with a spar-her 6, and a like wire 7 connects one of said batteries to said sparker, which comprises pi *otally-connected arms, the forward ends or jaws being indicated by 5, rear ends, which operate hand-lesfwhereby said jaws areactuated b'oing designated by 9. The wire. and 7 extend parallel longitudinally of one of said handles 9 and are held l in position. thereon bymcans of a covering 10. of rubber cloth or other suitable insulating material, and also by the staple ll. One of said wires is (:O1111G(2l;6(l to a plug .12 on one of the jau s 8, said plug being connected with a metal plate 13, preferabljgcopper, embedded in the jaw and having its outer pointed end l'lprojecting sligl'itly beyond the end of said jaw. The other wire extends to a plug on the opposite jaw and is connected to said Also connected with this plug is a wire 16, which. is embedded in the jaw and coiled around a pin 17 therein to form a coile, of the objects being to providean and the springlS, the outer end of said wire projecting through an opening in the jaw and extending laterally, as shown, said laterallyextending portion being arranged to contact the plate when the jaws are brought together and also being bent to allow it to slide past the projecting point 19 on said metal plate.- A coil-spring 20 is arranged between the handles 9, the tension thereof forcing the handles apart, and a set-screw 21 limits the movement of the handles toward each other.

In operation the operator grasps the hanj dies by closing one hand thereover and presses them together against the tension of said spring until the set-screw is encoun tered. This closing movement brings the I jaws 8 together, and the projecting point of j the wire 16, contacting the laterally-extending point 19 on the metallic plate 13, closes the circuit and creates a spark as the wire slips past said point. When the handles are l released, the tension of the spring 20 forces 5 the handles, and'consequently the jaws, apart and another spark is created as the wire slips back-over the point 19 in returning.

From the foregoing it is thought the construction operation, and advantages of my said invention will be obvious, and further explanation is not deemed necessary.

While the preferred embodiments of the invention are shown and described, it will be understood that I do not wish to be limited to the precise construction herein set forth, since various changes in the form, proportion, and the minor details of construction may be made without departing from the spirit or sacrificing any of the advantages of thednvention as defined by the appended claims.

Having thus described my said invention, what I claim as new, and desire to secure by 5 Letters Patent, is-- 1. In an electric igniter, a pair of crossed, hand-levers of non-conducting material, pivformed at their short ends with opposin jaws, one of the latter having a longitudinal slot or notch in its outer end, and the other having a recess or cavity in its inner face, a transverse pin arranged in said cavity, a coilspring upon said pin and having one of its ends pro ecting out of the cavity and curved to provide an electrical contact, and a metal plate secured in said slot in the other of said jaws and rojecting beyond said jaw to provide an electrical contact-point adapted to" otally connected intermediate their ends and I formed at t eir short ends with opposing f jaws, one of the latter havin a longitudinal .-slot or notch'in its outer fen and the other to having a recess 'orcavi'ty inits inner face, a transverse pin arranged in, said cavity, a

coil-spring upon said pin .fand" having one qfits ends projecting out of the cavity and I curved Lto provide an electrical" contact, a metal plate secured in said slot-in the other of said jaws and projecting beyond said jaw to provide an electrical contactwpoint adapted tov be engaged by the-curved, projecting end of s ,id spring when said jaws are opened 2'0 and closed, binding' posts upon said jaws and electrically connected with said spring and I 'saidplate, electrie cirouit conductors connected to saidbinding-pdsts and arranged upon the e'xterior'of one of said ,levers, and a covering. of. non-conducting material surrounding the handle portion of'thelast-mentioned lever and said conductors to' retain uthe latter -uppn' shown and described. 3. In an electric igniter', apair of crossed,

' hand-levers of non-conducting material, pivotally connected intermediate their ends and formed at their short ends with opposin jaws, one of the latter hav'in a longitudina 55 slot or notch in its outer on and the other ,having. a recess or cavity in its inner face, a

transverse pin arranged 1n said cavity, a coilspring upon said pin and having one of its 'ends pro ecting out of the 08.311 13) and curved 40 to provide an electrical contact, 'electric-cir-' cuit conductors electrically connected to said spring and said plate, said conductors being arranged "upon the exterior of one of said'levers, a covering of non-conducting 15. surroundin the handle ortion o mentioned-lever and sai conductors for retaining the latter-upon said lever, a spring for forcing said jaws afpart, and'an adjustable stop'carried by one 0 said levers and adapted to. engage the other for limiting the closing said lever, substantially asmaterial the last- 4. In an electric igniter, a pair of crossed,

hand-levers of hon-conductingmaterial. pivotally connected intermediate their ends and formed at their short ends with opposing aWs, coasting electrical contacts upon said jaws, electric-circuit conductors electrically connected to said contacts, said conductors being arranged upon the exterior of"one of said levers, 'a covering of non-conducting material surrounding the handle portion 'of the lash-mentioned lever and said conductors for retalning'the latter upon said le'veig'a coilspring arranged betweensaid levers forfOrc "ing them apart, and. a set-screw carried by one of'said levers and adapted to enga e the other to provide an adjustable stop for imiting the closing movement of said jaws, substantially asshown and described.
