摘要： The loading gate arrangement for a single action revolver comprises a loading gate pivotally mounted on the frame of the revolver by means of a rearwardly extending longitudinally disposed pivot stud, the loading gate having an integrally formed hub portion that is disposed in front of the pivot stud and is formed with retaining flange and detent surfaces. A trigger interlock element connected to and movable with the trigger and a loading gate interlock element located on the loading gate pivot stud cooperate to prevent the trigger from being moved and the hammer from being cocked when the loading gate is open and to prevent the loading gate from being opened when the hammer is cocked. A spring loaded gate retainer and detent member having a horizontally disposed arm portion extending forwardly from the loading gate and a vertically disposed finger portion extending upwardly adjacent the loading gate cooperates with the retaining flange and detent surfaces of the loading gate to retain the loading gate in position on the frame and to releasably detain the loading gate in its closed position when closed and in its open position when open. A laterally extending lug portion of the cylinder latch cooperates with the detent surfaces of the loading gate and with the loading gate retainer and detent member to withdraw the nose of the cylinder latch from engagement with a cylinder latch notch of the cylinder when the loading gate is open.

摘要： A firearm has a falling breechblock movable between retracted and battery positions. A striker, adapted to fire a cartridge, is mounted within a passage in the breechblock for movement between cocked and firing positions. The breechblock is provided with a trigger mechanism to control the release of the striker from the cocked position. The trigger mechanism includes a sear to engage the striker to maintain it in the cocked position, and a trigger to release the sear from such engagement. A cam plate member, whose discrete positions portray the firearms condition, is pivotally mounted upon the trigger mechanism and includes first and second surfaces defining an apex therebetween which are adapted to contact a roller secured to the sear. When the roller is in engagement with the first surface, the striker cannot be released from the cocked position by movement of the trigger. When the firearm is cocked and ready, the roller rests upon the second surface of the cam plate member so as to subsequently displace the cam plate member when the striker moves from the cocked position to the firing position. When the roller engages the first surface, or the apex of the cam plate member, the searing surface of the trigger is spaced from the sear so that the firearm will not fire should the trigger be pulled when the firearm is in a ''''half-safe'''' condition and then subsequently placed in an apparent cocked and ready condition. An indicating lever is mounted upon the trigger mechanism for pivoting movement in response to displacements of the cam plate member. A legend associated with the indicating lever is imprinted on the firearm to indicate whether the firearm is cocked and ready, cocked and safe, or fired.

摘要： A safety device for preventing unintentional firing of a gun comprising an easily-rotatable mass part mounted on the gun and having a stop which is in alignment with a recess in the triggering mechanism when the mass part is at rest, thus permitting movement of the triggering mechanism to fire the gun. When the gun is subjected to a force great enough to cause an unintentional firing, the mass part will be rotated by the force to a non-rest position wherein the stop is unaligned with the recess and prevents movement of the trigger mechanism for firing the gun. When the force diminishes, the mass part returns to its rest position to permit the gun to be fired.

摘要： A safety lock for small arms, said lock preventing opening, breaking, loading or discharge of the piece. The lock comprises a pin mounted in a selected portion of the small arm. The pin is axially advanceable and retractable by means of a separate externally applied key which at all times is retained by the owner. The pin, when in one of its extreme positions, engages a portion of the conventional small arms mechanism to lock the gun against firing, loading or even opening of the action. The gun is, therefore, rendered ''''tamper-proof'''' until application of the appropriate key.

摘要： A firearm has a receiver incorporating a longitudinally reciprocatable bolt assembly which is movable between retracted or recoil and battery positions in the receiver. A trigger, including a sear, is pivotally mounted in the receiver. A hammer is pivotally mounted in the receiver in such a manner that movement of the bolt from the battery position to the recoil position urges the hammer into a cocked position. The hammer includes a first sear abutment to engage a sear on the trigger, a second sear abutment and a bolt stop sear abutment. A disconnector is pivotally mounted on the trigger pin. A compression spring is interposed between the rearward extremities of the disconnector and the trigger to urge the forward portion of the disconnector into contact with the top surface of the trigger. The disconnector includes a hook sear abutment on an intermediate portion which is adapted to engage the second sear abutment on the hammer when the trigger is in a depressed position. Should the disconnector or hook sear be removed from the firearm, the bolt stop sear abutment on the hammer is adapted to engage the bolt assembly during movement from the recoil position to the battery position for preventing the conversion of the firearm into a machine gun.

摘要： An underwater impact actuated gun comprising a pole member used as a handle for thrusting against a fish to be shot and having a comparatively short gun barrel at the striking end. A weighted firing pin slidably arranged behind the cartridge by a compression spring is carried forward by its momentum upon striking a fish with the muzzle of the gun to fire the cartridge. The barrel is slightly tapered just in front of the cartridge slug, convergently in the direction of the muzzle end, to effect deformation of the slug to a diameter less than its original diameter, thereby minimizing blow-by to appreciably increase breech pressure and heat for more efficient burning of the explosive. The barrel is peripherally vented at its muzzle end in such a way as to permit escape of the water in the barrel, thereby minimizing its retardation of the slug as it is projected, while at the same time providing reactive forces minimizing recoil.

摘要： AN ACCESSIBLE "SAFETY" IS PROVIDED IN A HAMMER OF A FIREARM WHEREIN SAID HAMMER IS EXPOSED FOR MANIPULATION, WHEREBY ALTERNATE BLOCKING AND FIRING POSITIONS OF THE SAFETY ARE READILY ACCOMPLISHED AS CIRCUMSTANCES REQUIRE. IN THE SAFETIED CONDITION, THE SAFETY IS POSITIONED TO BLOCK ENTRY OF THE FIRING PIN THROUGH THE FRAME BY ESTABLISHING AN ABUTMENT AT OR ABOUT THE PLACE OF ENTRY OF SAID PIN THROUGH SAID FRAME. IN THE FIRING CONDITION, THE SAFETY IS POSITIONED TO PERMIT ENTRY OF THE FIRING PIN THROUGH THE FRAME, BY REMOVING SAID ABUTMENT FROM SAID PLACE OF ENTRY. THE SAFETY IS MANUALLY MOVABLE BETWEEN ALTERNATE POSITIONS, BEING HELD IN ALTERNATE "SAFE" AND "FIRE" POSI-
TIONS BY DETENT MEANS. A FEATURE IS DURABILITY WHICH INVOLVES A HARDENED SAFETY ELEMENT THAT IS MOVABLE AND THAT SEATS DIRECTLY IN THE HAMMER.-
