The locking member preferably includes a rod having a leading or first end which is at least partially insertable within the firing chamber of the weapon, and an outer sleeve including a trailing or second end which is expandable in a first direction to produce a tight frictional engagement between the sleeve and the inner wall of the barrel in order to secure the locking member within the firearm. The rod is at least partially insertable within a cavity in a first end of the sleeve such that the overall length of the locking member is adjustable to fit different weapons, for example a revolver and an automatic pistol.

Abstract: A muzzleloading rifle has a bolt with a laterally extending handle. The bolt is operationally connected to the cocking piece of the firearm by means of engaged cam surfaces of the bolt and the cocking piece which will permit the rifle to be cocked only by moving the bolt handle in an upwardly and rotational motion without any longitudinal movement of the bolt towards the cocking piece. After the firearm has been loaded by means of depositing a disc element with a primer element in the center bore thereof in the breech opening of the firearm, the firearm is placed in a firing condition by reversing rotational motion of the bolt handle. The disc element has a center bore which is adapted to receive a conventional nipple and a percussion cap, or in lieu thereof, and preferably, a shot gun primer. The latter is preferred in that it provides a hotter and more intense ignition of the gun powder in the muzzleloading rifle art.

Abstract: Apparatus for use with a bore spud for mounting and positioning a collimator with respect to a sighting device or scope on a firearm for bore sighting the firearm provides for adjustment of the collimator to an unlimited number of linear positions from below the center of the bore spud to positions above the bore spud. Greater bore sighting accuracy and more accurate adjustment of the sighting device or scope of the firearm is attained by enabling the collimator to be elevated and held at a precise location which matches that of the elevation of the sighting device or scope from the center of the firearm bore. The apparatus also enables angular adjustment of the collimator to an unlimited number of positions to permit alignment of the collimator with the firearm sighting device when the sighting device is offset and positioned at a location which is angularly displaced from a location directly above the bore of the firearm.

Abstract: A lockable firearm safety is incorporated into the bolt mechanism of a safety bolt to selectively block the forward motion of the hammer by either of two means: (a) preventing the trigger from moving rearward which movement would release the hammer permitting it to move forward and strike the firing pin; (b) by directly blocking the hammer from moving forward to strike the firing pin. When the safety bolt is placed in the safety position, the bolt may be locked in the safety position by means of a key. The firearm cannot be discharged until the safety bolt is unlocked and is moved to the fire position. The key is retained by the bolt unless the safety bolt is in the safety locked position.

Abstract: A locking device for locking into the bolt cavity of a firearm for making it non-functional, comprises a housing (1) which contains a lock cylinder (3) operable by means of a key which is introducible through a drilling protection (4) in the housing. The cylinder arm (8) of the lock cylinder (3) is non-rotatably connected to a follower (7), which has a flattening (9) which upon rotation of the follower pushes a wedge member (15) in the form of a steel ball between two blocking members (14), also in the form of steel balls, so that they are brought to extend partly from opposite sides of the housing (1). The locking device may be introduced into the magazine well of the firearm and located such that the extending blocking elements (14) will cooperate with e.g. the locking piece or receiver rails of the firearm in order to prevent the extraction of the locking device in its locked condition.

Abstract: An imaging self-referencing target tracker (10) for a laser weapon (12). The weapon generates a first beam of radiation (14) that engages a target (16) to form a beam hit spot (20) thereon. In a first embodiment, a target illuminator (22) (variant 1) illuminates the target with a second beam of radiation (23a). An optics subsystem (30) receives and separately images the first and second beams (23b, 24) of radiation. In a second embodiment, a blocking filter (40) is implemented rather than an illumination laser to pass only radiation at the target wavelength, thereby ensuring that the first and second beams of radiation are separately imaged. A controller (32) is programmed to steer the first and second beams of radiation to the desired target aim point (18) in response to information from the imaged first and second beams of radiation.

Abstract: An improved shotgun choke tube or fixed shotgun shot choking system is provided in which the 3-dimensional tightness or compactness of the pattern is achieved by the placement of radial projections within the choke tube at a selected distance from the muzzle, dependent upon the length of the shotgun shell being used, in conjunction with varying the dimensions of the projections depending on the nature of the components used in the manufacture of the particular shotgun shell used and the pattern results desired. Widest patterns (which are narrower or tighter than without the use of the choke tube) are achieved when the projections are positioned adjacent to the muzzle and/or with radial projections of minimal area contacting the walls of the wad/cup to retard its exit from the muzzle.

Abstract: A weapon discharge safety mechanism is designed in one multiple section piece for use with handguns and in two separate sections for use with rifles. The discharge safety mechanism includes a trigger guard housing with a bottom, first and second sides and an open top, which fits over and covers the trigger guard and trigger area of a firearm such as a pistol or a rifle. The trigger guard housing portion is releasably secured by a retention pin just behind the front of the trigger guard to hold the trigger guard housing portion in place covering the trigger guard. For handguns, an enclosed bullet trap housing is attached to the trigger guard housing portion. For rifles, this housing is separate. The bullet trap housing has a first closed end and a second open end, which fits over the end of a barrel of the gun and extends over the barrel a short distance.

Abstract: The present invention describes a firearm lock 20 having a combination lock 20 for firearms 10 which uses four tumbler locking mechanisms 22, 24, 26 and 28 connected to the firing trigger 16 mechanism by way of a trigger deactuator rod 38. The trigger 16 firing mechanism is disabled until the four or more tumblers 22, 24, 26 and 28 of the combination lock 20 are positioned in such a way as to allow a preselected combination or pin number on the tumblers to communicate with a tumbler pin 44, 46, 48 and 50 attached to the trigger deactuator rod 38. When the numbers of the disk tumblers 22, 24, 26 and 28 are properly entered, the tumbler pins 44, 46, 48 and 50 of the trigger deactuator rod 38 will seat in a single hole and thereby allow the trigger 16 firing mechanism to be actuated. If the wrong number of the combination is entered, the tumbler pin will contact a false hole after traveling only a short distance thereby locking and preventing the trigger mechanism from firing.

Abstract: A simplified missile tracker system that utilizes a single field of view while maintaining both the high resolution required for tracking and the wide field of view required for missile acquisition. The detectors in the acquisition portion of the field of view are clustered or ORed together to provide missile high signals of a weighted command for guiding the missile in elevation while greatly decreasing the required amount of detector signal processing. The bottom group of detectors are not clustered and they provide the high resolution and linear correction required for the accurate tracking of the missile in elevation. The azimuth tracking is provided by a synchronizing system and may be linear or nonlinear depending on the missile requirements.

Abstract: A dome assembly (50) adapted for use with a missile (32) having a longitudinal axis (42) parallel to a thrust vector thereof. The inventive dome (50) includes a crystal (30, 50) having a crystallographic structure that includes a plurality of planes (12, 14, 16), one of said planes (14) being more susceptible to failure than one or more of the other planes (12, 16). A surface around a missile sensor provides a place for mounting the crystal (30, 50) so that said plane susceptible to failure (14) faces approximately opposite to that of a positive velocity vector (34) of said missile (32). In a more specific embodiment, the crystal (30, 50) is a sapphire crystal (30, 50) having a crystallographic structure that includes positive n-planes (12), positive r-planes (14), and a c-plane (16). By design at nominal conditions, an r-plane (14) is approximately bisected by a plane formed by the normal of the c-plane (16) and a wind flow vector (36) parallel to a thrust vector of said missile (32).

Abstract: A phosphorescent or light-reflective member is disposed on a holder supporting an elongated light-gathering optical fiber formed of a light-gathering fluorescent plastic material. The sight is adaptable for use on rifles, handguns, bows, and other weapons requiring an aiming indicia. The light-gathering fluorescent optical provides a brilliant dot that is readily identifiable under bright light conditions, and the phosphorescent or light-reflecting member provides a supplemental light source which serves to provide an illuminated dot under low-light or dark conditions. The sight 10 effectively solves the problem of providing electrically-powered light sources for illumination of the aiming indicia under low light or dark conditions, or the requirement to precisely align the fiber or hollow tube with a light source disposed at the distal end of the fiber or tube spaced from the viewing end of the fiber or tube.
