| 1 | Continuous bore evacuation system | US955187 | 1992-10-01 | US5245905A | 1993-09-21 | Mark L. Bundy |
| A continuous bore evacuation system for aspirating the noxious gas products associated with the firing of tank rounds and for cooling all or part of the gun barrel between rounds. The bore evacuator employs an annular container which is fixed to the exterior surface of the gun barrel, preferably just ahead of the powder chamber. A plurality of canted ports lead from the container into the bore so that gas products can fill the container after a projectile passes the ports, and a compressed gas can be pumped in through check-valves to continuously clear the bore of gas products after launch. The ports may be arranged in a cochlear manner so that the flow of gas is substantially helical. In another embodiment, an aerosol solvent is injected into the compressed gas to prevent accumulation of propellant residue within the container, check-valves, and bore evacuator holes. | ||||||

| To reduce the concentration of the gases generated during firing in a combat space behind a gun barrel, a smoke exhaust device (8) is arranged in a middle zone of the gun barrel (7). This smoke ehaust device (8) is joined to the gun barrel (7) in a gas-tight manner in the outward direction and is connected, in the inward direction, to the caliber bore (5) of the gun barrel (7) via an obliquely extending blow-off bore (3) and via Y-shaped valve bores (2). Pressure is admitted into the valve bores (2) through a check valve (6) made in the form of an assembly of layered leaf springs. Good filling of the smoke exhaust device with gases generated during firing is thus possible along with very rapid closing of the check valve, which is decisive for the desired long blow-off time of the gases through the blow-off bore (3). | ||||||

| PURPOSE: To obtain a smoke exhaust device arranged in a middle zone of a gun barrel in order to reduce the concentration of the gases in a combat space behind the gun barrel in which a good action is ensured through a simple structure regardless of the size or the caliber of the gun barrel. CONSTITUTION: A blow-off bore 3 is made between the caliber bore 5 of a gun barrel 7 and a smoke exhausting device 8 while including with respect to Y-shaped valve bores 2. The valve bores 2 are closed by a check valve 6 made in the form of an assembly of layered leaf springs and arranged in the smoke exhausting device 8. Consequently, the smoke exhausting device 8 is filled well with gases generated during firing at the time of very rapid closure of the check valve 6. COPYRIGHT: (C)1992,JPO | ||||||
| 9 | Time-delayed gun bore evacuator | US12951102 | 2010-11-22 | US08567300B1 | 2013-10-29 | Daniel L. Cler |
| A bore evacuator for a gun tube may include a time-delayed discharge valve. The time-delayed discharge valve may open substantially simultaneously with the opening of the breech of the gun tube. Gas discharged from the bore evacuator may evacuate the bore of the gun tube. The time delay of the time-delayed discharge valve may be activated by gas pressure in the bore evacuator. The bore evacuator may include a pressure-regulating valve for regulating the maximum pressure in the bore evacuator. | ||||||
| 10 | Controlled-unaided surge and purge suppressors for firearm muzzles | US12652287 | 2010-01-05 | US08522662B2 | 2013-09-03 | Walter M. Presz, Jr.; Michael J. Werle; Bart Lipkens; Jason Gawencki |
| A Controlled Unaided Surge and Purge Suppressor for firearms uses the blast and plume characteristics inherent to the ballistic discharge process to develop a new two-step controlled surge and purge system centered around advanced mixer-ejector concepts. The blast surge noise is reduced by controlling the flow expansion, and the flash effects are reduced by controlling inflow and outflow gas purges. This is a C-I-P application. In the preferred C-I-P embodiment, the blast surge is mitigated via a slotted mixer nozzle; a first expansion chamber; a generally “wagon-wheel” shaped blast baffle with a vent hole; a series of alternating baffles, with vent holes, strategically located along the suppressor's inner wall surface; a second expansion chamber; and an exit opening. This preferred C-I-P embodiment contains no “outside” vent holes (i.e., throughbores) which extend through the suppressor's outer or longitudinal wall. Instead of ingesting ambient air through such throughbores and mixing that air with the muzzle gases, as shown in the parent application, the preferred C-I-P embodiment ingests and mixes chamber gases and contaminants with the muzzle gases while allowing fluid flow through and out the suppressor. It too though can control or eliminate the Mach disk. | ||||||

| A recoil-actuated gun scavenger for a gun having a bore, a breech, a recoiling mass, and a non-recoiling mass. The scavenger may include a pneumatic cylinder and a piston translatable therein. A rod may be fixed to the piston. The cylinder and rod may be fixed to respective recoiling and non-recoiling masses, or vice versa. The cylinder may include intake and exhaust ports with check valves, on both sides of the piston. The exhaust ports may communicate with an accumulator. The accumulator may discharge compressed air to jets located at the open breech end of the gun. | ||||||

| A device for limiting, controlling, and disposing of lead particles released from a firearm's openings and leakage areas rear of the muzzle. The device is composed of a cylindrical clear polycarbonate enclosure mounted on an aluminum frame which encloses the firearm and the shooters hands. A small opening at the rear of the cylinder allows the firearm muzzle to discharge the projectile. A restricted opening at the front of the cylinder allows the shooter to place hands and firearm within the enclosure. The clear Polycarbonate provides light entry and visibility while affording the shooter some protection against a malfunctioning firearm. The enclosure is under negative air pressure in relation to the environment outside the enclosure. The negative air pressure is provided by either the bullet retention system that the device is mounted to or separately by a connection to a commercially available High Efficiency Particulate Air (HEPA) filter vacuum. | ||||||

| A weapon system comprising a barrel for accommodating a projectile in a breech end portion, a muzzle end portion and a breech. The weapon system further comprises means for purging the barrel comprising a coanda slot, a coanda profile provided downstream of the coanda slot, and a source of pressurized gas, a duct which connects the source of pressurized gas to the coanda slot so that pressurized gas can be selectively supplied to the coanda slot and along the coanda profile, thereby entraining air in the barrel and exhausting debris and/or fumes through the muzzle end portion after firing of a projectile, and a valve for controlling flow of gas through the duct. | ||||||

The weapon system further comprises means for purging the barrel comprising a coanda slot, a coanda profile provided downstream of the coanda slot, and a source of pressurised gas, a duct which connects the source of pressurised gas to the coanda slot so that pressurised gas can be selectively supplied to the coanda slot and along the coanda profile, thereby entraining air in the barrel and exhausting debris and/or fumes through the muzzle end portion after firing of a projectile, and a valve for controlling flow of gas through the duct. | ||||||
| 19 | Ratchet-locking collar | US960115 | 1997-10-27 | US5802755A | 1998-09-08 | Richard W. Tortorici; Stephen M. Van Dyke-Restifo |
| A device that locks a threaded collar around a cylindrical gun barrel has alunger extending in a radial direction through the collar. The plunger rides upon a series of ratchet teeth, disposed around the circumference of the gun barrel. The ratchet teeth include ramps and steps. As the collar is threaded onto the gun barrel, the plunger rides up the ramp of each ratchet tooth and drops into the step of the next ratchet tooth around the gun barrel. When in place, the plunger is pushed backwards against the wall of the ratchet tooth and arrests rotation of the collar in the unthreading direction. To remove the collar, the plunger is lifted clear of the ratchet tooth. With the plunger held clear of the step of the ratchet tooth, the threaded collar can be unthreaded. | ||||||
