ABSTRACT OF THE DISCLOSURE The present invention provides: in combination a. a torch nozzle having a base end adapted to be connected to a source of fuel and an opposite end comprising a longitudinally extending nozzle por- tion terminating in a nozzle tip with a gas discharge orifice therein through which a fuel is passed for ignition, said nozzle portion hav- ing a longitudinal axis extending through said gas discharge orifice and b. an igniter attachment mounted on said torch nozzle and in- cluding: 1. a mounting base slidable on said torch nozzle and hav- ing locking means engaging said torch nozzle at a point adjacent said nozzle tip to fixedly support said igniter attachment on said nozzle; 2. a support having one end affixed to said mounting base and its other end spaced therefrom with a longitudinal axis defined by an imaginary line between said ends, said support being fixedly oriented relative to said mounting base; 3. a wheel support on said other end of said support; 4. spark generating means including a flint and a wheel, said wheel having a hub and an abrading rim and being mounted with said hub on said wheel support for rotation of said wheel thereon in a selected direction of rotation, said flint being carried on said support and having one end thereof contacting said rim of said wheel at a contact location thereon; said igniter attach- ment, wheel support and spark generating means being disposed on said nozzle at a point spaced rearwardly of an imaginary plane located at the end of said nozzle tip having said discharge orifice and drawn perpendicular to the longitudinal axis of said nozzle portion, said flint and the axis of rotation of said wheel being spaced towards said nozzle tip from the juncture of the axis of said support with said base, said spark generating means being disposed so that an imaginary line tangent to said rim at said contact location may be extended to intersect an extension of the longitudinal axis of said nozzle tip at a point spaced outwardly from said discharge orifice, whereby rotation of said wheel projects sparks outwardly of an adja- cent to said discharge orifice of said nozzle tip for ignition of fuel passing therethrough. -2-
