Flashback precluding torch

Abstract

A flashback precluding torch is attachable to an aerosol propane canister containing propane gas under pressure and has a fixture receiving fitting. The flashback precluding torch comprises an elongate hollow main body member having an anchored end and a free end, a gas flow inlet disposed at the anchored end, a gas flow outlet disposed at the free end, and a gas flow passage connecting in fluid communication the inlet and the outlet. An attachment mechanism is provided for removably attaching the anchored end of the elongate hollow main body member to the fixture receiving means of the aerosol propane canister. A manually operable main valve is operatively mounted on the elongate hollow main body member. A flame directing nozzle is operatively mounted on the main body member at the free end. A safety flow valve is operatively mounted on the elongate hollow main body member, so as to control the flow of propane through the elongate hollow main body member.

I claim:  
     
         1 . A flashback precluding torch attachable to an aerosol propane canister containing propane gas under pressure and having a fixture receiving means, said flashback precluding torch comprising: 
 an elongate hollow main body member having an anchored end and a free end, a gas flow inlet disposed at said anchored end, a gas flow outlet disposed at said free end, and a gas flow passage connecting in fluid communication said inlet and said outlet;    attachment means for removably attaching said anchored end of said elongate hollow main body member to said fixture receiving means of said aerosol propane canister;    a manually operable main valve operatively mounted on said elongate hollow main body member;    a flame directing nozzle operatively mounted on said main body member at said free end; and,    a safety flow valve operatively mounted on said elongate hollow main body member, so as to control the flow of propane through the elongate hollow main body member.    
     
     
         2 . The flashback precluding torch as set forth in  claim 1 , wherein said safety flow valve is operatively mounted on said elongate hollow main body member between said manually operable main valve and said flame directing nozzle.  
     
     
         3 . The flashback precluding torch as set forth in  claim 2 , wherein said safety flow valve is mounted within said gas flow passage of said elongate hollow main body member.  
     
     
         4 . The flashback precluding torch as set forth in  claim 3 , wherein said elongate hollow main body member comprises a cylindrical tube.  
     
     
         5 . The flashback precluding torch as set forth in  claim 1 , wherein said safety flow valve is substantially cylindrically shaped.  
     
     
         6 . The flashback precluding torch as set forth in  claim 5 , wherein said safety flow valve is mounted into said gas flow passage of said elongate hollow main body member by means of press fitting.  
     
     
         7 . The flashback precluding torch as set forth in  claim 6 , wherein said substantially cylindrically shaped safety flow valve comprises an elongate narrow main body and an annular flange disposed adjacent one end of said elongate narrow main body.  
     
     
         8 . The flashback precluding torch as set forth in  claim 1 , wherein said manually operable main valve is mounted on said attachment means.
