Abstract
A single tool, especially for use by gas welders, that combines a soapstone marker, a rotary spark igniter and a plurality of torch cleaning wires. The tool is of metal construction, of pencil-like shape, readily manually manipulable, and easily releasably carried in or on the clothing of a mechanic.
Claims2
A compound tool for welders comprising in combination;
- a rigid elongate tool body defining a cross sectionally smaller tip connector at its first tip end, a medial channel extending from its second cap end to a spaced distance from the first tip end and a marker channel extending through the tip end to the medial channel;
- a tip, having a cylindrical body and defining an axially aligned tip connector channel with threads to engage the tip connector of the tool body, structurally communicating with a truncated conic portion defining a medial marker channel in its apex portion communicating with a medial conic chuck chamber having therein a chuck defining a marker channel therethrough and adapted to constrict to frictionally engage a marker in the marker channel as it be compressed against portion of the tip defining the chuck chamber responsive to motion of the tip toward the body;
- an elongate cylindrical cleaning wire holder defining a medial marker channel to receive a marker, having a periphery adapted to frictionally fit within the medial channel defined in the tool body, and a length slightly longer than said medial channel, said cleaning wire holder having a plurality of axially aligned grooves in the peripheral surface thereof, at least some of said grooves carrying magnetically permeable cleaning wires slightly longer than said grooves so that their ends extend therefrom and means of creating magnetic force in the wire holder to releasably bias the cleaning wires in said grooves;
- and
- cap structure frictionally engageable upon the second cap end of said tool body to cover the medial channel defined therein.
