Definitions

  • My invention relates to fiame throwers or torches 'in which a combustible liquid is burned upon leavinga nozzle through which it is forced, and more particularly it relates to automatic igniting devices for such fiame throwers.
  • the object of my invention is to provide a reliable igniting device for such flame throwers, which will' not be put out of order by moisture or other incontrollable influences and which is moreover inexpensive, of light weight and easy to handle.
  • the igniters used heretofore for'such purposes utilized electric ignition, or an oxyhydrogen gas or other flame was temporarily or continuously maintained near the nozzle for igniting the combustible liquid as it leaves the nozzle. These ignition methods have thei disadvantage that they do not work reliably,
  • any light i weight nozzle can be used for directing the jet of burning liquid as e. g. oil.
  • an igniter for the continuous ignition of the jet leaving said i nozzle, it is suflicient to arrange in front of the nozzle an igniter according to the invention and this may be accomplished, for instance, by inserting the igniter into an igniter holder fastened to the nozzle.
  • This igniter holder which is not part of the invention, can be designed in such a manner that the igniter' :300,940, and in, Germany; August 23, 1927.'
  • Fig; 1 is a cross section on line 1-1 of Fig. 2 and Fig 2 is a'longitudinal section online 2-2 of Fig. 1.
  • N is the nozzle of a freely movable fiame thrower ,tube which is connectedto a vessel, not shown in the drawing, the oil jet to be ignited fiowing' through opening Kof the nozzle.
  • the igniter is fastened to the flamethrower nozzle in any suitable manner, for instance, by screwing or by inserting it into an igniter holder of the kind mentioned above.
  • These fastening devices are' not shown in the drawing as they are not part of the present invention.
  • the gniter consists of a tube O in which slides a piston member A and which is surrounded by a 'second tube P.
  • the inertia of the oil jet ⁇ a disk C being employed, if desired, to make a tighter contact with the walls of the tube.
  • a cross piece B is connected to the piston and actuating-wires L for the operation of the friction fuses D, of well known construction, are fastened'to said cross piece B( Any desired number of friction fuses may be provided-the drawing shows two ofthem-and they are put into operation when piston A is driven forward in tube O by the pressure of the liquid leaving the nozzle whereby the piston carries with it cross pieceB and wires L.
  • the ends S of the wires L are of such a size asto be prevented from passing out of the interier of the friction fuses D, a suffi cient length of the wire L being con'tained within each fuse so that upon withdrawal of pston A over cross piece B and wires Lso that the 'piston can be thrownofi by the jet of liquid under pressure.
  • the jet can now freely 'flow through tube O and is continuously ignited by the fiame which burns now -vividly in front of theigniter.
  • An igniting device which can Deinterchangeabiy fastened to the nozzle of a fiame i thrower, consisting of Valenciennes concentrically arranged around the nozzle, of fuses for the ignition of the Valenciennes and of mechanical means operated by* the jet of fiame thrower liquid upon leaving the nozzle, for the ignition of said fuses.
  • An exchangeable flame thrower igniting device consisting of a ⁇ set of' two concentric tubes adapted to be fastened upon a fiame thrower nozzle coaxialiy with the nozzle and containing between their-'walk"Valenciennes for maintaining the combustion of the fiame thrower liquid, a pisten slidin'g within the innermost of said concentric tubes, friction fuses connected to the Valenciennes by means ofa prining composition and mechanically connected to the piston in such a mannerthat the piston upon being advanced by the liquid leaving the nozzle actuates the friction fuscs and ignites the Valenciennes.
  • a device with the ,Valenciennes containing tubes, the pisten and 'the fuses being arranged n such a manner that the piston and fuses are thrown oif by the et of flame thrower liquid after ignition has taken place.
