ABSTRACT:
A portable electric cigarette pocket cigarette lighter has a pair of mating housing halves of plastic defining a hollow parallelpiped housing in which is disposed a pair of AA penlight batteries in side-by-side relation and electrically connected through a normally open switch to a spiral electric heating element of Nichrome positioned in the housing in axial alignment with an opening in the housing front wall of size sufficient just to admit the leading end of a cigarette therethrough into contact with the heating element. A plurality of peg members disposed on the housing halves position a plurality of sheet metal conductors which electrically connect the battery, heating element and switch in a series circuit completed by manual closure of the switch to energize the heating element to light the inserted cigarette. The switch includes contacts integrally formed with a pair of the conductors and operated by an actuator pivotally mounted on one of the peg members in an aperture in the front wall of the housing below the cigarette admission hole and biased to its open position by a torsion spring on the same peg member. The recessed positioning of the heating element inhibits intentional setting of fires.
