TORCH.
Application filedJuly 17, 1914. Serial No. 851,610.
' ticularly to tips for oxygen gas, hydrogen gas or oxy acetylene gas cutting or welding torches, In using this type of torch it has been found highly desirable to keep the tip cool so as to prevent back firing or premature ignition which puts out the flame. When this happens while making the weld the oxygen as oxidizes the metal and ruins the weld at t e same time cutting right down into the metal.
Another object in cooling the tip is to prevent damage to the tip which frequently ocoftime.
It is, therefore, the object of this invention to provide novel and eflicient cooling means which prevents excessive heating of the tip, thereby eliminating premature ignition and avoiding damage to the tip.
Another object of the invention is to provide a novel cooling means which may be readily removed and applied to the tipsand which may be adapted for tips of any character.
Further objects of the invention will appear as the following description is read in connection with the accompanying drawing, which forms a part of this application, and in which the figure is a perspective view showing the invention applied to an ordinary oxy acetylene burner with parts in section.
Referring more particularly to the drawing, 1 represents an ordinary oxy acetylene torch connected with the supply pipes 2 and Specification of Letters Patent.
. is in use normal position the coil may be readily re- Patented May 4, 1915.
3, the former adapted to convey oxygen to the burner head 4 and the latter adapted to convey acetylene gas-to said head. The head 4 is shown as provided with the usual form of tip 5 and in this instance the head is wound with a spirally arranged cooling coil 6 connected to a source of supply by the tube 7 and discharging through a similar tube 8. The tubes 7 and 8 are held alongside of the torch in any suitable manner and the supply tube is preferably provided with a regulating valve 9. The supply tube may be connected to any suitable source of supply and the cooling fluid which passes therethrough may beunder pressure or otherwise. These coils are preferably constructed of soft, copper tubing so that they .can be wound around the tip-s to conform thereto and lie against all portions of the outer surface. The unequal expansion between the tip and the coils efi'ectively holds the coil in position upon the head when the burner but when the parts are restored to moved for re air or replacement of the tip if found to e necessary. It is believed, however, that with the use of this coil that the tips will have a life equal tothe life of the torch proper.
What is claimed is:-
In a torch, a burner tip, a cooling coil removabl surrounding the tip and held in position tiiereon by expansion of the tip when in operation, supply and discharge pipes connected to the 0011, and means for controlling the supply of cooling fluid to the coil.
In testimony whereof I aflix my signatur in presence of two witnesses.
