Definitions

  • a gun barre1 has a locking bushing threaded on its rearward end and secured in position and the barrel [3O] Forelgn Apphcauo Pmmty Data end together with the locking bushing is inserted into Nov. 19, 1971 Germany 2157420 a breech casing such that the locking bushing positions the end of the gun barrel within the casing.
  • a [52] US. Cl 42/75 B second bushing is carried on the gun barrel and is [51] Int. Cl. F41C 21/00 threaded within the breech casing to remov ably [53] Field of Search 89/ cure the gun barrel within the breech casing.
  • the gun 42/75 76 R, 76 7 barrel is maintained in a proper relationship within the breech casing by a pin within the breech casing re- [56] References Cited ceived within a groove in the locking bushing.
  • the present invention relates to firearms including automatic weapons, more particularly. to the removeable mounting of a gun barrel on the breech casing of such weapons.
  • Another known structure enables a gun barrel to be threaded into the breech casing by means of threads arranged on a pin-like extension and a locking ring positioned on the same threads. The ring is rotated so as to press the breech against the rear face of the end of the gun barrel.
  • a firearm and particularly an automatic weapon has a gun barrel with a locking bushing secured on its rearward end.
  • the rearward end of the barrel together with the locking bushing is inserted into a breach casing.
  • the locking bushing positions the rearward end of the barrel within the breech casing.
  • a threaded bushing is carried on the barrel and is threadedly engageable with the breech casing when the rear end of the barrel is inserted into the breech casing.
  • the threaded bushing removeably secures the gun barrel and within the breech casing so that the gun barrel is exchangeable or replaceable by a different caliber barrel in the same firearm without any change in the relationship between the gun barrel and breech.
  • the rearward end of a gun barrel is indicated at l and hasan external thread 2 on the extreme end thereof upon which is-threaded a locking bushing 3.
  • the bushing and threads surround the cartridge chamber 1' in the end of the barrel.
  • the bushing J is threaded onto the barrel to such a point that the distance between the cartridge chamber end of the barrel and the breech projection bearing surfaces 4 of the bushing 3 correspond to a standard established by the industry and by governmental agencies. This distance is indicated at l".
  • the bushing 3 is secured in its threaded position on the barrel 1 by means of a weld. solder or a suitable adhesive.
  • the breech projection bearing surfaces on the bushing 3 are formed by means of recesses as known in the art.
  • the bushing 3 is provided with an external groove or notch 7 which receives a pin 9 firmly secured within the breech casing when the cartridge chamber end of the barrel is inserted into the breech casing indicated at 8.
  • the pin 9 thus positions the barrel 1 and bushing 3 into the correct position with respect to breech block 6 having breech projections 5 and also secures the barrel and bushing assembly against any rotary movement with respect to the breech block.
  • a second bushing 10 having external threads 10' is slideably carried upon the barrel 1 and is threaded into suitable internal threads provided within the breech casing 8.
  • the bushing 10 urges the barrel 1 by means of the bushing 3 against an abutment 11 within the breech casing to fix the position of the barrel with respect to the breech casing.
  • the quick and precise interchanging of barrels of different calibers is particularly useful in hunting since this feature enables the hunter to use the same weapon to shoot at various types of game. For example, a smaller caliber barrel would be used for small game. such as rabbits than for larger animals, such as deer. in a matter of seconds the hunter can replace a gun barrel in the field without the use of tools.
  • the present invention has disclosed a-structure or device by which it is possible to insert new barrels of the same or different caliber into the same weapons without any changes to the breech distance and without any necessity for readjustment or test-firing of the new barrel.
  • a further advantage of the present invention is that certain manufacturing tolerances may be disregarded since these tolerances can be compensated by the adjustable features of the present invention.
  • a gun barrel having a locking bushing threaded on its rearward end and axially adjustable thereon, and a second threaded bushing on said barrel threadedly engageable with a breech casing and in abutting engagement with the forward end of said locking bushing when the rear end of the barrel is inserted into said breech casing to removably secure the gun barrel within the breech casing, a breech block secured within said breech casing.
  • said locking bushing being secured on the rear end of the barrel in a position corresponding to a predetermined standard distance betiveen the rear end of the barrel and the forward end of said breech block so that the gun barrel is exchangeable or replaceable by a same or different caliber barrel in the same firearm without any change in the relationship between the gun barrel and breech.
  • said locking bushing has a groove therein, and a pin within said breech casing and positionable within said groove to locate the barrel and locking bushing in proper relationship within said breech casing and to prevent rotary movement of said barrel and locking bushing with respect to said breech casing.
