368 results about "Muzzle" patented technology

The muzzle of a firearm is the end of the barrel from which the projectile will exit. Precise machining of the muzzle is crucial to accuracy, because it is the last point of contact between the barrel and the projectile. If gaps exist between the muzzle and the projectile, escaping propellant gases may spread unevenly and deflect the projectile from its intended path. In the case of rifled weapons, the contour of a muzzle is designed to keep the rifling safe from damage, so it is commonly recessed or protected by a convex "crown". When firing a gun, a flash is often seen at the muzzle and is produced by the hot gases escaping the barrel. The size of the flash depends on various factors such as barrel length, type and amount of powder, etc. Flash suppressors are attached to the muzzle of the weapon to diminish these effects.

Firearm safety device

InactiveUS6526684B1Simple and rugged constructionImprove reliabilitySafety arrangementGun barrelEngineering
A firearm safety device invention for handguns is disclosed. The safety device (10) prevents accidental firing of a gun by children, but is easily removable by an adult in 5 to 10 seconds even in pitch darkness. The safety device includes a lock sleeve (26) with an expandable end plug (30) which is inserted through the muzzle (16) of a gun barrel (14). With the end plug positioned in the firing chamber, a lock rod (24) is inserted into the lock sleeve to force expansion of the linear slotted (32) end plug sufficiently to prevent the safety device from being removed from the barrel. Withdrawal of the lock rod from the lock sleeve to allow removal of the safety device is prevented by a knurled cap (22) which is threadedly attached to a knurled enlarged end portion (28) of the lock sleeve. Since the safety device is able to rotate freely in its assembled position in the gun, any attempt to unscrew the knurled cap without holding the enlarged end portion of the lock sleeve stationary will be unsuccessful. A child will not be able to remove the knurled cap since he or she will hold the gun in one hand while fiddling with the knurled cap with the other hand.

Firearm Suppressor and Injector Assembly

A suppressor assembly for connection to the muzzle of a firearm includes an injector portion for connection to the muzzle and a suppressor portion for connection to the injector portion. The injector portion has a chamber for holding a quantity of fluid. When a firearm is discharged and the projectile passes through the injector portion, fluid is drawn from the chamber and into the suppressor portion to thereby shield the suppressor portion from full impact of gases associated with the fired projectile. The injector and suppressor portions can be operated independently and the injector portion can also function as a muzzle break, flash suppressor, and so on.

Process to produce a silencer tube with minimal wall thickness

A method for reducing the weight of a silencer without compromising durability. By reducing the silencer housing wall thickness weight is removed from the silencer module. Areas on the housing where material is removed are primarily selected based on the internal pressure generated in a given chamber of the silencer. Further, removal of external material is selected based on the baffle arrangement. Individual chamber pressure is influenced by the muzzle pressure of the host firearm and the baffle style and baffle orientation within the silencer being used.

The invention discloses a mortar shell bullet mechanical trigger fuse with a penetration time self-adaptive function. The mortar shell bullet mechanical trigger fuse comprises a body, a pneumatic insurance mechanism / trigger ignition mechanism, an inertia ignition mechanism, an explosive-proof mechanism, a recoil insurance mechanism, an anti-recovery mechanism of the recoil insurance mechanism, a delay arming mechanism, a setting mechanism, a detonating tube, a booster tube and a bottom screw. Two insurances of the fuse respectively depend on an inner ballistic environment and an outer ballistic environment during launching to be released, and the two insurances of an explosive-proof piece are both in an insurance state at a filling stage and before getting out of a gun muzzle, so that thesafety is good. A fault insurance characteristic is possessed, in case that the recoil insurance mechanism is accidentally relieved, the fuse can be automatically switched into a fault insurance state, and safety in a credible service processing environment is guaranteed; a booster tube adopts an energy-gathered charging structure, so that the detonating capacity is high; the fuse has the characteristics of redundant ignition and redundant fire insulation, is high in reliability, and can ensure the treatment safety of unexploded ammunition explosives; and the fuse is simple in structure, is easy to process and low in cost.

Digital signal processing back biased hall effect muzzle velocity measurement system

A system for precisely measuring muzzle exit velocity of a “muzzle loaded” mortar projectile fired from a mortar tube using two back-biased Hall effect sensors for projectile gas ring channel detection. The system includes a back-biased Hall effect sensor block, a digital resolver electronic circuit and a computer software interface. The back-biased Hall effect sensors are located in a calibrated sensor block attached to a mortar tube. As the projectile metal casing passes a face of the sensors, the sensors trigger and release, providing two electronic pulses. The pulse edges are captured in the resolver electronics, containing a discriminator circuit for filtering all input pulses to distinguish between a projectile loading event and a projectile firing event. Once a valid firing event is detected, an output of precision timers is presented serially to a computer where it is processed and displayed by a computer software interface.
