Definitions

  • LAURENS MORGAN HAMILTON OF IPARIS, FRANCE, CHARLES LEVEQUE JOLY, OF NEW YORK, N. Y., AND GRANVILLE ALEXANDER POLLOCK, OF PARIS, FRANCE.
  • This invention relates to means for cooling machine guns, and its object is to provide improved means for this purpose.
  • the present invention differs from the above, in that it consists in means for cooling machine guns, having in combination, a casing surrounding the barrel of the gun, and having openings at its front and rear ends, a rotary fan within said casing, and mounted on said barrel, and over an aperture in the wall thereof rearward of the muzzle, and means for causing the compressed gases resulting from the explosions of the charges during fire, and issuing from said aperture, to rotate said fan, and thus produce a current of cooling air through said casing.
  • the invention further consists in the construction of the fan for use with the cooling means as described in the preceding paragraph, having a rotor comprising a plurality of tubes, terminating at one end in noz- 1923.
  • Serial NO. 636,158
  • each of said tubes being formed integral with or attached to a fan blade.
  • Fig. 1 shows an elevation of a machine gun provided with our improved cooling means.
  • Fig. 2 shows a part sectional elevation of the rotor within its casing on the gun barrel.
  • Fig. 3 is a sectional elevation on the line A-A Fig. 2.
  • Fig. 4 is a section on the line BB 3
  • Fig. 5 is a plan of the rotor.
  • a convenient method of securing the casing to the barrel is by means of braces 3.
  • a sleeve 4 constructed of some hard metal, preferably steel, the inner wall of which sleeve is preferably provided with corrugations.
  • a rotor 6 preferably having four nozzles 7, to each of which is attached a fan blade or vane 8.
  • the nozzles 7 communicate by means of pipes or tubes 9, with an annular well 10, surrounding the barrel 2.
  • the device is preferably so arranged that the hole 11 will be situated about three inches from the muzzle of the barrel.
  • a plurality of cooling fins 12, preferably made of copper, or other material of high heat conductivity, may be secured by welding, or other convenient means, to the barrel, so as to increase the surface coming in contact with the cooling stream of air in the casing, and thereby increase the cooling etficiency of the device.
  • the operation of the device is as follows When the gun is fired, the gases resulting from the explosion of the charge, cause a very considerable pressure in the barrel, and it' ;has been found that a considerable pressure still exists at a distance of three inches from the muzzle. A portion of the gases by reason of their own pressure, is forced through the hole-1'1 into thewvell '10, from Where it escapes through pipes 9 to the nozzles 7,; from which it is discharged, impingin-g on the inner Wall of the sleeve 4, thereby causing the-rotor (land vanes 8- to be rotated. The corrugations tend to increase the reaction of the gases issuing from the nozzles.
  • the an blades 8- are so shaped as to draw :air through the casing, preferably in the direction of fire.
  • the invention consists broadly in the provision of means for air coolingthe barrel of-a machine gun, said means being operated by the pressure 0f the gas resulting from the explosion of the charge, it will beseen that the invention is not limited to the particular details of construction described, and illustrated, as these can obviously be varied, Without departing from its scope;
  • adevice' for cooling machine'guns the combination 'of an open-ended gun casingsurrounding the barrel of thegun, said gun barrel having an aperture therein, a rotary an Within one end o-fsaid'casing provided With a Well-and mounted on said gunbarrel over said aperture, said 'fa-n having a plurality-0f blades and tubes attached to said blades, said tubes connecting With said Well,-and nozzles on theends of said tubes to cause :a change of .directionin the gases escaping from said aperture vvhereby the *fan is rotated and air caused to circulate through" the gun casing.
