CIGAR LIGHTER Application filed April 7,

This invention relates to electric cigar lighters.

One object ofthe invention. is to provide av lighter of this type which is simplev in construction and whichis adaptedto beproducedinlarge quantities at a. very low cost.

Another object of the invention is to provide a lighter of this'type which is composed of comparatively few-parts andwhich may be quickly and readily assembled for use.

@ther objects of the invention. will appear from the'detail description.

The. invention consists. in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is a perspective" of: aportion of the panel of a vehicle on which. the instrument and accessories are usually mounted, the invention being shown thereoin Fig. 2v is at side elevation of the lighter. Fig; 3 is. a perspective of the unitary upport. which isadapted to fit into -the2casing; Fig.- l-is alongitudinal section. Fig. 5 is; azview showing; the severalparts in the. course of assembling;- Fig. 6. is. a section on line 66 of Fig; 4. Fig. 7- is a plan.

Thesinvention is-e-Xemplified in a device comprising a tubular sheet-metal casing 16 which .hasone of its ends open. and its other end 11 turned inwardly to form. a: flange which hasa hole-12therein for the. conduc- Y torlwires. A member ldeof suitable insulate in'g: materiahsuchas lava, and formedv of. a single. 131966,.19 adapted tobe inserted into the tubular casing and to support,.in properly. connected relation, the resistance 1 element andzthe switch for controlling the circuit through said element. Supporting member; lt is adapted to. be in'serted through the. open end of'the casing lOandcomprises a cylindrical head 15, which fits into and closesthe open end of; the casing; and an integral: shank 16,. which is adaptedzto extendinto thelcasingandlis narrowed so as to. leave spaces in the casing: for: the switch anditheconductor wires A countersink or recess 17 is: formed. inthe outer; face of electrically connected to a hollow rivet 20 which extends transversely through and is tained with the casing.

fixed in the shank 16 of the support 14'. The other end of resistance element 18 is connected by a portion 21 which extends through the head to a hollow rivet 22 which extends through and is fastened to the shank 16 above therivet 20. ()ne of. the conductor wires 23 has its end fixed under one of the flanges of the rivet -and the other conductor wire 24 has-one of its ends riveted under one of the flanges of a hollow rivet 25 which extends through theshank- 16 and through one end of. a resilient switch str p 26. The other end 27 of the switch strip is normally spaced from the rivet 22 and is adapted to be flexed into contact with said rivet to complete the electric circuit for the operation of the resistance element. The lower end 28 of the strip 26' is bent under he lower end of the shank 16 to lock the strip against rotation.

A button 29 isheld in a hole 30 formed in one side ofthe casing. 10 and is provided at its inner end with an. enlargement or head 31 which causes the button to be re Switch strip 26 presses the'button 29 outwardly so that no separate spring is necessary for retracting the button. A crossrib32 is formed on one of the side faces of shank 16 adjacent the inner end of the button. 31. to serve asan abutn'ient for. resilient strip 26 which will prevent excessivev pressure of the button 29 froindistorting the resilient strip 26.

The conductors 23 and24 extend through a cupsha.ped washer 3 twhich is adapted to .be inserted through the openend of casing 10 and slippeddownwardly into position to close the hole 12 in the casing. The condiictor wires are threaded throughan opening 35 inthe washer 34, and thelatter is preferably formed ofinsulating. material. The casing is formed with an annular out-turned head 36 whichserves asa stop to-prevent the casing from slipping from the fingers when the lighter is being used. An annular grooveST is formed in the outer periphery of. the head. 15, so that by indenting-the casing. at one point, as at 38, toenter said groove, the supportingmember. 14: will be retained against axial movement in the..casing 10. A longitudinal groove 39 is formed in the outer periphery of head 15 between groove 37 and the lower end of the head, andthe casing 10 is indented, as at 40, to enter. said groove to'secure the member lt against rotation in the casing, so that the switch strip 26 will remain in engagement with the button 29.

In assembling the device, the resistance element is placed in position in the member 1%, its terminal .21 is extended under one of the flanges of the rivet 22, and the latter is then pressed into position; the other end 19 of the resistance element and the terminal of conductor 28 are secured in connected relation' by fastening the rivet 20 in the shank 16; the switch strip 26 and the terminal of conductor 24 are then fixed to the member let by fastening said rivet in the shank 16; the member 14:, with the resistance element, switch strip and conductors connected thereto, is then inserted into the casing 10, button 29 being held in opening 30 and the switch-strip being aligned with the button during insertion, so that the button will be held in the casing by said strip. The casing is then indented at 38 and 40, and thereupon the entire device will be assembled.

The lighter is adapted to be held by asimple form of clip 41 which may be secured to the dashboard or any other suitable support. To operate the lighter, it is only necessary to press the button 29 which will complete the circuit through the resistance element 18. When the button is released, the switch 26 will open and the circuit will be. broken.

The invention exemplifies a cigar lighter, which is simple in construction; in which all of the electrical connections are mounted on, and made to, a unitary member which is adapted to be inserted into casing after the connections have been made; in which the tubular casing may be formed of sheet metal; in which the resilient switch-member holds the operating button in place and retracts it; in which the support is provided with an abutment for preventing distortion of the spring; in which the electrical connections are made by means of rivets fastened in the supporting member, and which makes it possible to easily assemble the device and at a low cost.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.
