ELECTRIC Application filed November My invention relates to electric lighters oi that type in which a length or section on a resistance conductor furnishes the lighting heat. The niain object ot the invention to produce a siinplej euicient and conveniently manipulated device which will readily light cigars and cigarettes hut which is particularly usetul and efficient tor lighting and relighting pipesa Another object or" the invention is to inalre the general contour and shape of the device that of a deslr telephone Whereliv to proped- VJ vide a substantial supporting hase, estal or grip section and a head in which the heat producing eleinent is located.

Another iinportant feature ot the invention is the localization ot the heat produceleinent entirely Within the head ot the device and the elimination of resistance or transformer structures in the hase ot the device Where such structure might hecoine dangerous when overheated.

Another important feature of the invention is the provision of a lighting nose or lug on the head of the device on Which nose or lug a section of the heating element is arranged to he accessible tor the lighting oit cigars and cigarettes and particularly tor being inserted into the bowl of a pipe to cause lighting thereof;

Another important object is to provide simplified and inexpensive construction involving the use ot sheet metal 'tor practically the entire structure.

rllhe above and other features ot iny invention are incorporated in the structure shown on the drawing, in which,

Figure 1 is a vertical diainetral sectional view ot the complete device;

Figure 2 is a sectional view on plane 2 2, Figure l;

Figure 3 is a front elevational view or" the heating element supporting core, and

Figure et is a rear vieu7 et such core and heating element supporting structure.

The supporting traine shown comprises the cylindrical hase 10 having the stiiiening head 1l around its lower edge and having the dished top Wall 12. rlhis hase preteraloly is stamped troni a single-piece ot sheet inet-al.

The pedestal or grip part 13 is also stamped integral troni sheet inetal and at its lower end this cylindrical grip part is ra diallycontracted to torni the annular shoulder 14 for seating against the inateria-lsur- LGETER.

t part and grip part together.

rit it t'ie cylindrical grip part 13 is e5: iuided to torni a cylindrical seat 19 entendi.. iacfonal planej the seat receiving al closure cap 20. The

an is detachable, it having the peripheral or. with one or inore notches registration With projections 23 on tle seat 19 Will perniit Withdravval or the can. l-oivev r7 when the cap Aed to carry its notches ayvay from the s, the cap will he locked to the lip part.

p rlhe supportin hloclr or core for the resistance element eats in the traine 19 and comprises the tront Wall 24 and the annular flange E25, the flange having the helical groove 26 for receiving the resistance eleinent shown in the torni ot a Wire helix. The support C is of sonne electrically nonconducting and heat refractory material such as porcelain. front Wall thereoic is the nozzle or lung Q8 having one or more grooves 29 tor receiving the resistance or heat producing elements. The housing cover 2O has the opening 30 through Which the nozzle projects and the nozzle ot such diameter and length that it inay he inserted in the howl ot a pipe to bring the heated resistance conductor into contact with the tobacco to cause ignition thereof. rihe resistance helix entends troni the

terininal loraclrets

31 and 32 secured against the rear sides ot the front Wall Q41-, As shown, the groove 29 extends across the outer end and along the sides ot the nozzle and the resistance helix extends 'from the terininal 3l through the hole 33, then around one of the nozzle grooves 29 and back through the hole 34, then through the hole 35 and around the other nozzle groove and hach through hole 36 troni Where the helix entends through the passageway 37 to the exterior ot the core and then through the helical groove 26 and then haclr through the hole 38 to connect with the terminal 32. The terininal 32 is secured to the switch mechanisin S supported in the grip part 13 and controlled hy push button 39 projecting Extending axially troni the
