Multiple flame torch tip and method

Abstract

Torch tip for a torch, the tip adapted to be in fluid communication with a fuel gas and oxygen source for generating a flame, the torch tip including a tubular or substantially tubular body having a plurality of flame emitting spaced orifices, wherein the tubular body preferably is substantially U-shaped and includes a pair of spaced substantially parallel elongated legs. The torch tip can be used to simultaneously heat a plurality of closely spaced pipes for ease of removal or attachment to an object such as a reversing valve.

What is claimed is:  
     
         1 . A torch tip for a torch, said tip comprising: 
 a stem having an inlet end, and    a tip head in fluid communication with said stem spaced from said inlet end, said head comprising a pair of spaced, substantially parallel legs, each leg having a plurality of spaced orifices for emitting a flame.    
     
     
         2 . The torch tip of    claim 1   , wherein said tip head has a bisecting plane, and wherein the centers of said orifices are each located at an angle of from about 30 to about 60° to said bisecting plane.  
     
     
         3 . The torch tip of    claim 2   , wherein said angle is about 40°.  
     
     
         4 . The torch tip of    claim 1   , wherein said torch tip is coupled to a torch member for distributing fuel gas and an oxygen source to said torch tip, said fuel gas and said oxygen source producing, upon ignition, flame jets that emanate from said plurality of spaced outlet orifices.  
     
     
         5 . The torch tip of    claim 1   , wherein said tip head is U-shaped.  
     
     
         6 . The torch tip of    claim 1   , wherein said legs are parallel, and wherein each of said orifices on one of said legs is opposite a corresponding orifice on the other of said legs.  
     
     
         7 . The torch tip of    claim 1   , wherein said plurality of orifices on each leg are equally spaced.  
     
     
         8 . The torch tip of    claim 1   , wherein each of said orifices is formed in a portion of said leg that is reduced in curvature relative to a circular cross-section.  
     
     
         9 . The torch tip of    claim 9   , wherein said portion that is reduced in curvature is planar.  
     
     
         10 . A method of simultaneously attaching or removing a plurality of pipes to an object, comprising: 
 providing a torch tip comprising a stem having an inlet end, and a tip head in fluid communication with said stem spaced from said inlet end, said tip head comprising a pair of substantially parallel legs defining a space therebetween, each leg having a plurality of spaced orifices for emitting a flame;    positioning said torch tip such that said plurality of pipes is within said space between said legs; and    causing flames to emit from said plurality of orifices to simultaneously heat said plurality of pipes.    
     
     
         11 . The method of    claim 10   , wherein said plurality of pipes are attached or are to be attached with solder, and wherein heating said pipes liquifies said solder.  
     
     
         12 . The method of    claim 10   , wherein said tip head has a bisecting plane, and wherein the centers of said orifices are each located at an angle of from about 30 to about 60° to said bisecting plane.  
     
     
         13 . The method of    claim 10   , wherein said plurality of orifices on each leg are equally spaced.  
     
     
         14 . The torch tip of    claim 10   , wherein each of said orifices is formed in a portion of said leg that is reduced in curvature relative to a circular cross-section.  
     
     
         15 . The torch tip of    claim 14   , wherein said portion that is reduced in curvature is planar.
