To all whom it may concern;

Be it known that we, VIc'ron E. .EKTROM and THOMAS G. Bdmor'raiv, both citizens of the United States, and residents of Tomahawk, in the county of Lincoln and State of "Wisconsin, have invented a new and Improved Electric Cigar-Lighter, of which the following is v a full, clear, and exact descriptiou. I V

This invention relates to a new and 1mprovedcigar lighter, of a type in which the. heat of ignition is obtained by passing a cur rent through unexposed resistance wire bent so as to offer a plurality of juxtaposed lengths within a small compass. It has been tound with such electric cigar lighters of this type which are now on the markehthat a considerable quantity of expensive platinum wire, which is also readily breakable, is necessary in order t0 obtain the required heating surface when connected to the-ordinary electric light circuit which runs at one hundred and ten volts. y

It is the object of this invention to so construct a cigar lighter that the current can be transformed or stepped downto a lower voltage and increased amperage, enabling the use of a much coarser and stronger wire, of entirely less expensive material, which will offer a greater heating surface, and will come to the glowing point in the shortest possible space of time. i

A further ob ect of this invention is to provide a device. whiclpwill, be simple in construction, inexpensive to manufacture, strong, durable, and readily accessible for the purpose of renewing the parts.

These and turther-objects together with the construction and. combination of parts, will be more fully described hereinafter and particularly set IOItll in the claim,

REIEGITlIIg more particularly. to the separate parts in Fig, 1 is illustrated the form which is adapted tobe set on a shelf or cigar case, and consists of a base 1,-a body 2 and a lighting head 3.

I i In the form illustrated in Fig. 2, the

lighter is suspended from a suitable support, in juxtaposition to a cigar counter or the like, by means of electrical conducting wires, indicated at 4., and consists also of a body portion 2 and a lighting head 3. Arranged in front of the lighter, there is provided an opening 5, through which a cigar is to be inserted when it is desired to iight'the same. Arranged in back ofthis opening 5,.tliere is provided a non-conducting block 6, secured to which is provided an exposed resistance wire 7 of any suitable material, such as a" pliable alloy. This resistancewire 7 is bent back-and forth along the taco of the block 6, so as to ofi'er a plurality of linlrsthereot in close and yet spaced juxtaposition, so as to offer the greatest amount of glowing sur- The ends of the resistance wire '7 are connectedflto suitable terminal screws 8' and 9, which in turn extend to the secondary winding 10 of a transformer 11, which is preferably located within the cigar lighter,

It will be seen by reference to Fig. 5 that I a secondary circuit is formed through the resistance 7, the secondary coil 10, and the wiresronnecting them together. The secondary winding 10 is arranged in close juxtaposition to a primary winding 12 of the transformer 11. This primary winding 12 is connected by, wires 13 and 1d to a suitable source of electricity, indicated by the socket 15. This circuit through the wires 13 and 14 and .the primary winding 12 is provided with a break at 16.. The ends of the wires at the break 16 are provided with contacts 17 and 18, which are adapted to be brought into engagement by means of a push button 19. .The latter extends out 2 through the body of the lighter in any convenient position, where it will be readily accessible to the user. The contact 18 is preferably made of a springy material, so

that when the pressure onthe button 19 is released, itwill automatically spring out of engagement. with the contact 17.

The utility of the device will be readily understood from the above description. When it is desired to light a cigar, the butt end is inserted through the opening 5 and juxtaposed to the resistance wire 7'. The button 19 is then pressed, so that a circuit is completed through. theprimary coil 12, thereby causing a currentto pass through the secondary coil 10 of the transformer 11. This transformer 11 may be controlled in any suitable manner to make and break the circuit, so as to. have a constant impulse of current through the secondary winding 10. The current passing through the secondary circuit will cause the resistance wire 7 to glow, thereby enabling theuser to light his cigar. Inasmuch as-the. voltage of the current can be reduced inamount by the character of the windings in the transformer 11, it will enable the use of a'coarse and in- GXPGIlSlVQT$1St3I1CG w re, which will last a long time, and which, when worn out, can

'be renewed at little or no expense. As soon as the pressure is relieved on the button 19, the primary circuit is disconnected, thus discontinuing the flow 'of current through thesecondary circuit;

While we have showntwo embodiments tions and alterations whichwe may make within the scope of the appended claim.

Having thus described our invention, we

claim as new and desireto secure byLett'ers Patent I In a cigar lighter, the combination with a body having a, plurality of cavities therein,

of atransformer located in one of said cavities, a lightin head located onthe face of said body an transformer, contacts in another of said cavities within said body, normally out of engagement with each other and connected with said transformer, and a push-button Within said last-mentioned cavity. and adapted to bring said contacts into engagement, and. projecting above the surfaceof said body, whereby it may be readily operated, said lighting head comprisin an insulating block, a resistance wire bent ack and forth along the face of said block, terminal screws connected to said insulating wire, and a cover plate for said block, having an opening therein adapted to permit access to said resistance wire. a In testimony whereof we have signed our names to this specification'in the presence of two subscribing witnesses.
