Abstract A cordless electric igniton tool having a handle portion comprising a housing containing a battery, a pair of terminals and a normally open switch in circuit with the battery and the terminals. A pair of elongated electrical conductors extend from the terminals, the free ends thereof being bent at right angles toward each other. An electrically conductive tube extends along and in electrical contact with a major part of the length of each conductor for stiffening the conductor and for increasing the electrical conductivity thereof. Electrical insulation is provided between the tubes to keep them apart and around the tubes for safety. A supporting member is mounted on the inturned ends of the conductors, and resistance heating wire is carried on the supporting member and connected to the conductors, the heating wire on closure of the switch having a temperature above 1400* F., whereby the tool is capable of igniting lamps, candles, cigarettes, cigars, pipes, gas stove burners and the like.
A cordless electric ignition tool, comprising: a housing; a battery in said housing; a pair of adjacent terminals electrically insulated from each other in said housing and electrically connected to said battery; a normally open switch in said housing in circuit with said battery and said terminals; a pair of elongated unitary electrical conductors electrically connected to said terminals and extending therefrom away from said housing, said conductors capable of retaining shape at high temperature; a supporting member of heat resistant, electrically insulating material having spaced openings, the free ends of said conductors being received within said openings whereby the supporting member is supported at the free ends of the conductors; resistance heating wire on said supporting member electrically connected to said conductors, said heating wire on closure of said switch heating to a temperature above 1400 degrees F.; tubes of electrically conducting material on said elongated unitary electrical conductors extending the major part of the length of said conductors and in electrical contact therewith for stiffening said conductors and for additional conductivity; and electrical insulating material between and enclosing said conductive tubes.
