Definitions
- JOHN VOLLMER JOHN VOLLMER, OF ESSEN, GERMANY, ASSIGNOR TO FRIED.
- This invention relates to gun-barrels having a breech-piece screwed on an A-tube.
- the object of the invention is, chiefly, to provide an arrangement which will render it possible to assemble and disconnect easily and without injury to the screw thread the breech-piece and the A-tube.
- the drawing represents a longitudinal section of the parts in question of a constructional example of the invention.
- the gun-barrel consists of an A-tube A and a breech-piece B, the latter being formed with a jacket portion 6 which envelops the rear portion of the A-tube.
- the connection between the A-tube and the breech piece is obtained by means of the screw threads a 6 which are so designed that during the operation of screwing the two parts together, a certain amount of clearance exists, both in the axial and in the radial direction between the screw thread at of the A-tube and'the female thread b in the breech-piece, the clearance in the radial direction remaining even after the assembling operation is completed.
- the A-tube is cut, both in front and in rear of the thread a with annular groves a for the reception of a ring C made of a comparatively soft material, brass, for instance.
- the external cylindrical surfaces 0 of the rings C are intended to bear against cylindrical surfaces 1) prepared in the breech-piece B- Conical wedges D are driven into recesses the walls of which lie on the front end face of the breech-piece and, on the other hand, on the rear face of a collar a formed on the A-tube, the wedlges D being secured in position by a ring fixed over the collar a
- the operation of screwing the breech piece on the A-tube is performed, with great ease, owing to the clearance existingin the screw connection a 6 When the operation is nearing its end, the surfaces 0 of the rings C bear against the surfaces 6 of the breech-piece B, so-as to accurately center the A-tube within the breech-piece.
- the recesses for the wedges D are bored, the wedges driven in and secured by means of the ring E.
- the screw threads a b are made to bear against each other in the axial direction with so great a pressure as to insure a rigid connection between the breech-piece and the A-tube.
- the clearance existing in the radial direction between the threads (1 6 remains and is not lost even when the A-tube expands on firing.
- the pressure then set up is supported by the surfaces 0 6 so that gripping of the screw thread is prevented. Neither can gripping occur on the bearing surfaces 0 5 since the rings C are made of softer material than the A-tube and breech-piece, and are flattened out by excessive pressure.
- the wedges D having previously been removed, the breech-piece can be unscrewed from the A-tube by a slight effort and without injury to one of the parts.
- a gun barrel and breech-piece screwthreadedly united said union being formed so as to provide a radial clearance between the parts
- said gun barrel and breech-piece being formed with bearing surfaces on both sides of said screw-threads,'said surfaces being curved concentrically to the bore axis of the gun barrel and cooperating to maintain said radial clearance when the parts are screwed together.
- a union for a gun barrel and breechpiece characterized by the provision of screw-threads on the 11 barrel, cooperating screw-threads on th: breech-piece, said screw-threads being so formed as to allow a clearance radially between the screwthreads of the gun barrel and breech-piece, said breech-piece being provided with cylindrical bearing surfaces, rings of comparatively soft material secured to said gun barrel and contacting said cylindrical bearing surfaces, to maintain said radial clearance.
- An arrangement for connecting a gun barrel and breech-piece comprising screwthreads formed upon the gun barrel, cooperating screw-threads formed upon the breechand breech-piece for closing the axial clearpiece, said screw-threads being so formed as ance between said cocperating screw-threads. 1 to provide a clearance axially and radially
- the foregoing specification signed at Es- When the breech-piece is connected to the sen, Germany, this 24th day of June, 1920.
