To all whom it'mcty concern: I I

Be it known that I, PErrnR J. Frsorinn, a citizen of the United States, andresident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Cigar Lighters, of wh ch the following is a specification, and wh1ch are illustrated in the accompanying draw in s, forming a part thereof. I i %he invention relates to cigar lighters, a-ndhas as an'object the provision of a device of this nature which may be used without grasping the fuel tank. A further object is the provision of an electrically ignited lighter that will not yield sparks when the movable member returns to normal position to extinguish the blaze.

An illustrative embodiment of the invention is shown in the accompanying drawings, in which a Fig. 1 is a vertical longitudinal view on the line l1of Fig. 4;; w I

Fig. 2 is 'a detail side view partlyin sec tion on line 11 of Fig. 4, showing certain of the parts in a different position from that shown in Fig. 1; 1

Fig. 3-is a diagram of circuits; Fig. 4 is a bottom-plan view of the cover, and the parts attached thereto Fig.= 5 is a detail side view of the partscarried by the cover showing a modified form; Fig. 6 is a detail bottom plan view of the parts shown in Fig. 5, and r Fig. 7' is a detail side view of'some of the parts shown in Figs. 5 and 6, in a different position from that shown in Fig. 5.

A box lO-capa'bl'eof containing the dry cell 11 and induction coil 12 may be-uti l ized as a base for the device and may have a fuel sparking upon th'e return movement) .ofthe reservoir, as 13, containing alcohol, gasoline or other readily inflammable fuel mounted on its cover- 14 A. wick tube-15 is shown projecting upwardly from the cover 16v of the reservoir 13 and the reservoir and tube should be formed of electrically conductive material in order that the wick tube-may form one side of a -spark gap whereby an electric spark may beproduced closely adjacent the end of the wick. I

.An electrode 17 projecting from an insulating plug 18 is shown carried by a tube 120. projecting; through the cover 14g of the box. A 'eollar 21 which fits, and in its normal position closes the top of the wick tube, V

forming an extinguisher, may be secured to the end of'tube 20. A shoulder 27 on the col lar is adapted to limitthe return movement of the tube 20. For oscillation the tube is mounted in the bight 22 of a strap 23 having i-tsends rigidly secured to a shaft .24 mounted in brackets 25 on the underside vof the cover It. The projecting ends 'ofthe shaft 24;, at the sides of the-box 10, may have knurledfi-nger disks-26 rigidly secured thereon which 'may .be grasped by the user to manipulate the tube 20. v 1

1 To hold the tube 20 in its normal position, as shown in Fig. 1,-a leaf spring, as 28, may be secured to the underside of the cover 1.4: and may press upwardly on the strap 23, shoulders 29 being provided to coact with the edges of the strap. To cushion the return movement of the tube, the end 30 0f the leaf spring 28'may beextended'beyond the shoulders-.29 and may be contacted by a-pin 31, carriedby the strap23, when the shoul der27 approaches the wick tube 15.

The primary circuit of the-induction eoil 112 may be-closed by a member 32 bifurcated fora purpose to be explained and rigidly mounted on the end of the tube 20. Coact- -ing with said member 32 is shown-a plunger 33 slidably mounted in a sleeve 34- and plunger, but is swept across the head by downward movement of the tube. To save batteries it is desirable to avoid tubeQO, s'uch sparkingbeing useless asthe blaze is about to'be extinguished by completion of this movement. To prevent such sparkingthe contact of the member32 with :the head 37-of the'plunger may be prevented by a device -88ain'the nature of'a' paw-l of insulating material, -as fibre board." This 'pawl is shown as pivotally mounted between the projections of the bifurcated member 32.

On the downward movement of the end of this tube 20 the pawl swings freely upward and does not interfere with" the contact between thehead 37 of the plunger and memtubeQO in each-direction, the member 32 is out of I contact with the h'ead37 of the ber 32. On the downward movement the 5, 6, and 7 differs from that above described merely in the means for mounting and moving the tube 20. In this form of the device the end of the tube 20 is shown as mounted in a collar 40 carrying the member 32 on one side and a projection 41 at the other side which projection is pivotally mounted in a bracket 42, securedto the cover 14. An end 43 coacts with a compressed spring 44 to hold the tube 20 in normal position. To move the tube 20 to ignite the lighter a lever 45 is shown mounted in a bracket 46 and having an end 47 in engagement with part 43, which lever may be actuated by a push button 48 to cause rearward movement of the tube 20. Button 48 is shown as maintained in a normally raised position by a spring 49.

'The electric circuits for the device may be arranged as shown in Fig. 3. When the tube 20 is swung rearwardly a circuit will be closed from battery 11 through wire 50, the head 37 of the plunger 33, contact 32, mounting23' of the tube 20, spring 28, wires 51, 52, make andbreak 53, primary coil 54 of the induction coil 12, wire 55 to battery. A condenser 56 is bridged about the make andbreak 53, as is usual. The action of the vibrator, the circuit of which has just been traced will be to induce current of high voltage in the secondary coil 57.

I When the electrode 17 approaches the wick tube 15 a path for the high voltage current is formed from the secondary 57 of the spark coil by wire',60, electrode 17,

spark gap, wick tube 15, reservoir 13, metal strip 58 connected to the downward projection of one of the screws 59 used to se ;cure the reservoir to the cover 14, as shown in Figs. 4 and 6, wire 51-to. the other end of the secondary coil'57. The'spark jumping across the gap mentioned will ignite the fuel in'thewick 61. sparkswill be formed as electrode 17- passes both, sides of the end of the wick tubeand hence the fuel will hav two opportunities to be ignited.
