MAGAZINE-TUBE FOR AIR-GUNS.
Specification of Letters Patent.
Patented Dec. 8, 1908.
Application filed April 17, 1908. Serial No. 427,681.
To all whom it may concern:
Be it known that I, NILLIAM A. Hen; PRIN, a cltizen of the United States, residing at Philadelphia, in the county of Philadelplua and State of Pennsylvania, have mvented certain new and useful Improvements in Magazine-'lubes for Air-Guns, of which the following is a specification.
This invention relates to certain new and useful improvements 1n air guns, and consists in the construction of the parts that center the true barrel in the outer barrel or magazine-tube at the muzzle, as well as in certain novel features of construction that provide means for connecting the parts, whereby the cost of manufacturing is reduced, and the assembling of the parts is fa- 1 cilitated, as will be hereinater set forth.
In the accompanying drawings Figure l, is a side elevation of the magazine-tube or false barrel, showing the cap, frustum and inner barrel in place. Fig. 2, is a plan view of the sheet metal blank as it appears before being formed into the magazinetube. Fig 2*, is a plan view of a modification of the blank. Fig. 3, is a detail section of the muzzle end of the magazine-tube showing the inner barrel centered therein. Fig. 3 and 3 are detail sections of modifications. Fig. 4, 4 and 4 are views of the centering cone or frustum, and Fig. 5, is a front elevation of the cap for the outer end of the magazine-tube.
Referring to Figs. 2 and 2 of the drawings, A is the blank that is punched, or otherwise manipulated to form therethrough an aperture o, and such blank adjacent to its opposite end has formed therein a plurality of indentations a, or in lieu thereof a continuous indentation The indentation being of sufficient depth to bulge the metal and form on the inner side of the tube projections or abutments a. If-desired, instead of forming the abutments a", from the sheet metal blank, I may rigidly attach an inner ring or band (Z which will serve the same purpose as the integrally formed abutments.
In the preferred form of construction the sides of the projections or humps a, that are furthest from the muzzle project substantially at right angles from the inner surface of the magazine-tube, and the front faces are inclined so that the frustum may be forced into the magazine-tube from the muzzle end, and the sheet metal blank A, after having been punched is formed into a cold-shut tube which forms the false barrel or maga zine-tube A.
The inward projections or humps 0/, provide bearings or a seat for a frustum or barrel centering or holding cone B, which may be stamped or pressed into shape, such part having a flange b, and an opening which is slightly less in diameter than the external diameter of the inner barrel, and this frustum may be shaped shown by Figs. l, and l or may be made as shown by Figs. 3 and 3", where the apex is extended and bent inward to provide a seat for the end of the barrel F.
The funnel shaped piece or frustum B, is at its larger end practically the same diameter as the interior of the magazine-tube, and when in place it will be seated against the projections or abutments carried by the tube, and will be prevented from being moved toward the muzzle by the pressure of the inner or true barrel against the inner side of the frustum.
In assembling the parts the magazine-tube A, is compressed upon the flange 1), of the frustum B, by forcing over the muzzle end of the magazine tube a cap C, which is centrally apertured as shown by c, and one side of the cap has a slit or opening 0, in which is seated the front sight C, which sight may be soldered in the slit or it may be riveted to the cap.
In Figs. 3 and 3 the magazine-tube carries bands (Z (Z, held in place by any suitable means as by solder, or by rivets, or projections formed on the bands to enter apertures or indentations formed in the magazinetube, and if desired these bands may extend to the forward end of the 111agazine-tube.
By use of the preferred forms of construction the parts are held together solely by friction, and to complete the magazine-tube a slidable band is placed upon the tube to cover the opening a, through which the shot is fed to the magazine, and beyond the opening a, there is the usual fixed band E.
The magazine-tube, made in accord with my invention, is ready to be placed upon the body of the rifle, or the rifle frame, and the L inner barrel F, will be centered by the in clined walls of the frustum without the necesj sity of using a mandrel or other tool, and this is a great convenience, not only in manufac- 1 turing, but to the user, as the inner barrels are often removed from the magazine-tube.
It will be noted that the inner or true barrel bears against the frustum, and that the flange thereon transmits the pressure imparted by the inner barrel against the magazine-tube, so that there is no liability of forcing the frictionally held cap off of the magazine-tube.
I claim 1. In an air-gun, the combination with a magazine-tube or outer barrel having adj acent to the muzzle a plurality of inward extending projections to form bearings for a hollow frustum, of a hollow frustum adapted to engage said projections and to be held thereby against movement toward the muzzle.
2. In an air-gun, the combination with a magazine-tube having a plurality of inward extending projections to provide bearings for a hollow frusturn, of a hollow frustum seated in the magazine-tube to engage the projections, and a cap mounted upon the end of the magazine-tube.
3. In an air-gun, a magazine-tube having a plurality of indentations shaped to provide on the inner side of the magazine-tube projections with straight ends, a hollow conical guide for engagement with the straight ends of the projections, and a cap carried by the end of the magazine-tube, for the purpose set forth.
4. As an article of manufacture, a longitudinally split magazine-tube having a plurality of inward extending projections integral therewith, and inner-tube centering member, the periphery of which engages such projections and the inner side of the magazine-tube, and a centrally apertured cap mounted upon the exterior of the magazinetube to engage with the centering member, the parts being maintained in frictional con tact, substantially as shown.
5. In combination with a sheet -metal magazine that is bent in tubular form and provided with non-connected edges, a seat or inward projecting portion stamped in the tube adjacent to its end, a frictionally held inner barrel centering device that is held against movement toward the muzzle by engagement with the inward projecting portion of the magazine-tube, and a cap mounted upon the muzzle end of the magazine-tube; the cap carrying a front sight, substantially as shown.
6. In a gun, a magazine tube having adj acent to its muzzle a part of less internal diameter than the major internal diameter of the balance of the tube, an inner barrel centering device provided with a flange for engagement with the inward extending part of the magazine tube, and a cap mounted upon the end of the magazine tube such cap extending beyond the inner barrel centering device.
In testimony whereof I affix my signature in presence of two witnesses.
WILLIAM A. HEILPRIN.
