| 141 | QUICK-ASSEMBLY BREECH PLUG FOR MUZZLELOADER FIREARMS | US12430213 | 2009-04-27 | US20090265973A1 | 2009-10-29 | Angel Calvete Zumalde |
| The invention relates to a quick-assembly breech plug for muzzleloader firearms, allowing a quick assembly and disassembly and being extremely practical, simple to manufacture and having a low cost, wherein said breech plug comprises a cylindrical body (1), configured to be internally coupled in a rear end (10′) of a barrel (10), and a head (6) configured to define a limit coupling position of the breech plug inside the barrel (10), wherein the cylindrical body (1) externally comprises a male thread (2) having at least two starts located close to a front end (3) of the breech plug, opposite the head (6), according to a plane perpendicular to an axis of revolution of the cylindrical body (1), said male thread (2) being configured to screw into a female thread (10″) located internally in the rear end (10′) of the barrel (10), preferably 4 screw ridges. | ||||||
| 142 | Muzzle-loading firearm and easily removable breech plug for use therewith | US11197811 | 2005-08-05 | US07316092B2 | 2008-01-08 | David C. DeLeeuw |
| A muzzle-loading firearm includes a breech plug for mating, non-threaded engagement with a housing located at the breech end of an axial bore of the firearm barrel. The plug includes a cylindrically-shaped body member having opposite first and second ends and an outer surface between the ends and configured so that when the plug is positioned within the housing, the outer surface is spaced close to the inside surface of the housing to facilitate insertion and removal of the plug from the housing. The body member is formed with a primer chamber for receiving and retaining a primer or a percussion cap at the first end, and a passageway for fluidly communicating the primer chamber with a powder charge at the second end. The body member may have a powder chamber for receiving and retaining at least part of a powder charge at the second end when the firearm is loaded. The material and dimensions of the body member may be such that the body member deforms radially outwardly so that the outer surface of the body member and the inside surface of the housing form an essentially gas-tight seal during firing. The powder chamber contains much of the powder residue generated by the firing. In order to insure that the muzzle-loader cannot be readily used as, or converted to, a breech-loading firearm, different muzzle-loader/breech plug design features are presented. With one design feature, the maximum cross-sectional inner dimension of the housing is less than the diameter of the bore of the barrel. With another design feature, alignment of the firing pin and primer chamber (or hammer and percussion cap holder) is along an axis not centered with the axial bore of the barrel. The cross-sectional shape of the housing and breech plug may be non-cylindrical. For example, the cross-sectional shape can be oblong, essentially triangular, etc. Thus, conventional, breech-loading ammunition will not be effectively usable in the muzzle-loading firearm. | ||||||

| A bolt assembly for a direct gas firearm includes a plurality of sealing rings. In an embodiment, there are three rings with ring gaps cut at about a 45 degree angle and the middle ring is flipped so that the angle of the gap of the middle ring is approximately 90 degrees from the angle of the gap of the two outer rings. In an embodiment, the angle of the ring gap of at least one of the plurality of sealing rings is between 0 and 90 degrees and the ring is configured so that the ring gap is minimized once the ring is installed. | ||||||
| 144 | Revolver for firing high velocity ammunition | US11270944 | 2005-11-10 | US07254913B2 | 2007-08-14 | Jason Robert Dubois; Simon Michael Muska; Gary E. Zukowski; John W. Avedisian; Brett Curry |
| A revolver for firing high velocity ammunition includes a frame, a cylinder, a barrel, and a firing mechanism. The revolver may include one or more of the following, each of which is especially adapted for use in the context of firing high velocity ammunition: spacers for adjusting a barrel-cylinder gap, for eliminating broaching of the rearward surface(s) of the barrel; a forcing cone formed in the rearward opening of the barrel for accommodating deformed projectiles; a reflective surface (e.g., mirrored surface) provided on the cone and/or barrel rearward surfaces, for reducing erosion resulting from using high velocity ammunition; gain-twist rifling in the barrel for a smoother transition to full projectile velocity; a larger diameter, hardened firing pin bushing for minimizing brass flow in the rearward direction; and a front sight assembly that minimizes lateral shift or drift of the sight pin during firing. | ||||||
| 145 | Pipe mortar | US10400921 | 2003-03-28 | US07171886B2 | 2007-02-06 | Ralf-Joachim Herrmann; Henning von Seidlitz; Marold Elspass; Rolf Bartolles |
| To seal a pipe mortar, a sealing element (3, 6) is inserted between the pipe (1) and the base (2), with the element elastically balancing out the axial relative movements between the pipe (1) and the base (2). The sealing element (3) is preferably prestressed, with the gas pressure supporting the sealing effect. The sealing element (3, 6) can be a U-shaped or L-shaped steel ring. In the U-shaped sealing element (3), the legs (3.1) are axially prestressed to the extent that the sealing ring (3) and the pipe (1) or the base (2) are pressed together to produce an adequate seal. In the L-shaped sealing element (6), the inside leg (6.1) produces the gas-tight connection when the pipe (1) and the base (2) are screwed together. A sealing lips (6.2) of the sealing ring (6) elastically absorbs changes in length between the pipe and the base that occur during firing. | ||||||

| A gun system has a two piece cannon assembly that is separated between a removable chamber instead of a traditional breech, and a projectile forcing cone. The chamber has a plug at one end that can accommodate any type of ignition system, and the other end is open and is attached to the barrel with a connection fitting. High pressure gases created by combustion of the propellant are sealed with a high-pressure gas compression seal at the interface between the chamber and the barrel. The connection fitting provides an attachment for a rear cannon bearing slide, which rides on rails attached to the main support structure, and also reacts any torque induced into the barrel from the actuation of the chamber/barrel locking collar. A turntable upon which are mounted two chamber elevating/support mechanisms and two projectile loader/rammer mechanisms is positioned around one of the main support structure legs. | ||||||
| 148 | Firearm with pivoting barrel | US235701 | 1994-04-29 | US5513550A | 1996-05-07 | Roger C. Field |
| A firearm for firing cartridges (2) which may in at least one embodiment fire caseless cartridges (2), having a barrel (1) pivoting around a pivot point (11) from a firing position to a loading position, and back to the firing position. A fixed wall (16) is positioned behind chamber (19) when barrel (1) is in the firing position, which absorbs the recoil of a fired cartridge (2). A plug (6) may be used to seal chamber (19) when firing caseless cartridges (2). The pivoting movement of barrel (1) may be activated against spring (4) by gas pressure from a fired cartridge (2) escaping from a hole (3) in barrel (1). Residual gas in barrel (1) may be used to move rammer (7) against spring (8) and rammer (7) then chambers a cartridge (2). Barrel (1) then returns to the firing position. | ||||||
| 149 | Breech lock, especially for hand firearms | US151900 | 1993-11-15 | US5398593A | 1995-03-21 | Nehemia Sirkis |
| A bayonet-connector-like breech lock has a breech housing and a breech block with at least two radially projecting locking components. The enlarged region needed to rotate the locking components takes the form of an annular space wherein a locking sleeve is fitted to rotate between an open and a locked end position. The locking sleeve has a widened section for each locking component aligned with a widened part of the breech block bore in the open end position. The annular space is completely filled by the locking sleeve and the pushed-in breech block. | ||||||
| 150 | Base and obturating ring arrangement | US647746 | 1991-01-30 | US5147971A | 1992-09-15 | Rolf Bartolles |
| An obturating arrangement for a gun barrel of the type having a right-angled obturating ring having its axially extending arm disposed within a recess in the base ring at the end of the gun barrel and its inwardly radially extending arm engaging, in a known manner, a breechblock wedge insert. In known arrangements of this type powder residues generated during firing, which may accumulate in the recess of the base ring and become lodged underneath the supporting face of the obturating ring arm projecting into the recess, may cause the basic play between the obturating ring and the breechblock wedge insert to be reduced, so that malfunctions during the closing of the breechblock wedge may occur. To overcome these drawbacks and also to increase operational reliability and lengthen the time between cleanings, the free end of the obturating ring arm projecting into the recess is arranged at a distance from the base surface of the recess while the rearwardly projecting end of the bead defining the inner wall of the recess is configured as a support for the obturating ring. The free end of the arm projecting into the recess preferably includes a sloped surface tapering toward the exterior of the obturating ring, and thus produces a stripping effect. Powder residues possibly still present in the enlarged volume of the recess can be blown out by fast flowing gases passing through a reduced opening between the bead end and the radially disposed arm. | ||||||
| 151 | Barreled weapon | US523719 | 1990-05-15 | US4982646A | 1991-01-08 | Wilhelm Machmer |
| A barreled weapon including a forward barrel segment which is tiltable about a trunnion through the intermediary of an actuating arrangement, and additionally includes a rear barrel segment which is similarly pivotable about the trunnion whereby the barrel segments, when oriented in their coaxial position, are sealed through the utilization of a sealing ring at a joint or separating location without necessitating any axial displacement of one of the barrel segments. The weapon includes a casing which is conducted along a screwthread and wherein, in the coaxial position of the barrel segments, the actuating arrangement rotates the casing so as to cause the latter, in conjunction with the sealing ring which is arranged thereon, to axially slide over the separating location between the barrel segments. | ||||||
| 152 | Bolt assembly | US828504 | 1986-02-11 | US4723369A | 1988-02-09 | Joseph A. Badali |

The body of the bolt is of reduced diameter with respect to the bolt head which carries the locking lugs. A cartridge depressor is mounted in association with the bolt body to effectively increase the diameter of the bolt body in the vicinity of the magazine to that of the bolt head. | ||||||
| 153 | Obturator ring for a cannon | US696415 | 1985-01-30 | US4709616A | 1987-12-01 | Rolf Bartolles |
| An obturator ring for location between a sliding wedge-type breech block and a base ring in the barrel of a cannon to provide a seal and allow satisfactory closing movement of the obturator ring. The ring comprises an angle section with a radial flank having a disc lining on the external side facing the breech, the flank which is parallel to the axis of the bore of the barrel having on the external side a cylindrical lining. The linings are deformable, incompressible and capable of being forced over their widths against the base ring or the wedge insert by the flanks which deform under gas pressure. The linings are interconnected in the corner cross section of the obturator ring via a number of connecting rod-like members disposed in bores through the obturator ring; the flanks are joined through a rounded corner portion which allows flexure to effect through the tips of the flanks. The linings provide a large sealing surface of which the minimum width is greater than one-half of the length. | ||||||
| 154 | Explosive powder driven fastening element setting device | US631529 | 1984-07-18 | US4611738A | 1986-09-16 | Peter Jochum |
| A setting device arranged to use caseless propellent charges for driving fastening elements, such as bolts, nails and the like, into a hard receiving material, includes a casing containing an axially slidable barrel forming a feed element at its rearward end. A counterpressure member is slidably movably supported within the casing in axial alignment with the barrel. The feed element and counterpressure member combine to form a combustion chamber for the caseless propellent charges. A frusto-conical surface is formed on the counterpressure member and seats in sealing contact with a complementary frusto-conical surface in the casing. | ||||||
| 155 | Leak detector for seal ring of gun breech mechanism | US623552 | 1984-06-22 | US4566368A | 1986-01-28 | Rolf Bartolles |
| A gun breech mechanism has a barrel formed with a backwardly open shell chamber, a breech block displaceable into a position rearwardly closing the chamber, and a seal ring between the block and the barrel and having an inner face exposed in the chamber and an outer face lying against the block and barrel. A passage opens at the outer seal-ring face for detecting thereat a gas pressure in excess of a predetermined superatmospheric pressure and a device is provided for generating an alarm signal when such excess pressure is detected. A guide bore formed in the block has an end into which the passage opens and an indicating element having an end exposed at the bore end and slidable in the bore between an inner position with its element end close to the passage and an outer position spaced therefrom. Thus pressurized gas can flow through the passage from the outer seal-ring face to the bore. A spring urges the indicating element inward toward the bore end, that is into the inner position. In addition in the inner position the element is at most flush with a surface of the breech and in the outer position it projects from the surface of the breech. | ||||||
