| 141 | Rifle comprising a stock, a forearm and a barrel | US10351704 | 2003-01-27 | US20030150151A1 | 2003-08-14 | Manfred Orth |
| The subject matter of the invention is a rifle (1) comprising a stock (40), a forearm (30) and a barrel (20), the barrel (20) being releasably connectable to the stock (40) and said barrel (20) being fastenable to said stock (40) by bringing the forearm (30) into locking engagement with said stock (40) by means of a locking device (50), the locking device (50) being spring-loaded and the spring (60) being compressed by an actuation member (57) for the purpose of unlocking. | ||||||
| 142 | COMBINATION BARREL ADJUSTMENT AND MAGAZINE CUTOFF FOR A TAKEDOWN FIREARM | US09775090 | 2001-01-31 | US20020162266A1 | 2002-11-07 | David Richard Clay |
| A flex-plate adapter for a takedown firearm has front and rear sections. The rear section includes adjustment screws to change the gap between the front and rear sections. Guide pins are included for assuring proper alignment between the front and rear sections. The adjustable gap between the front and rear sections of the flex-plate adapter provides compensation for thread wear. A magazine cutoff provides a manual cutoff for retaining ammunition in the magazine whether the rifle is assembled or disassembled. A cutoff lock prevents the accidental movement of the magazine cutoff. | ||||||
| 143 | Folding stock | US10003172 | 2001-10-31 | US06470617B1 | 2002-10-29 | Thomas M. Gregory; Robert A. Kincaid |
| A folding firearm comprises a stock supporting a receiver, the receiver defining a bore for receiving a first end of the firearm barrel. A forearm is operably pivotally connected to the stock. The forearm includes a barrel securing mechanism having a securement member. The firearm barrel has a surface adjacent to the first end for engaging the securement member. The securement member is matingly engageable with the surface of the barrel. The securement member, in response to pivotal movement by the forearm, moves into engagement with the surface to urge the first end of the barrel into the bore of the receiver when the firearm is pivoted into a firing position. The firearm also includes a locking mechanism capable of selectively locking the forearm in the firing position. | ||||||
| 144 | Munition for low-pressure firing of projectiles from large-caliber guns | US182085 | 1994-04-14 | US5402729A | 1995-04-04 | Pierre Richert |
| Ammunition comprising a cylindrical case (1) with one of the closed ends having coaxially a concentric chamber (1a) capable of receiving a propulsive means for a projectile lodged in the case. The propulsive means consists of a blank cartridge (2) lodged in a diffusing means (3), the cartridge and diffusing means assembly being inserted into the coaxial chamber of the case. | ||||||
| 145 | Take-down rifle | US458777 | 1989-12-29 | US5020260A | 1991-06-04 | Thomas M. Houghton |
| A take-down rifle which permits easy removal and reassembly of the barrel to the receiver portion of the rifle and incorporating a system for effectively accommodating for wear in the mating parts thus providing for proper alignment between the rifle's two main components. The system includes a barrel bracket secured to the forearm, an adjustable collar threaded on the receiver end of the barrel and in contact with the barrel bracket, and the bonding of the barrel to the forearm by means of a low durometer elastomeric adhesive. Adjustment for wear can be made by turning the adjusting collar in a direction to cause the barrel to move in a direction away from the barrel bracket which accommodates for any thread wear between the receiver and the barrel. | ||||||
| 146 | Single-shot survival rifle | US11781 | 1979-02-14 | US4299046A | 1981-11-10 | Maxwell G. Atchisson |
| A portable lightweight rifle which is primarily intended for use as a survival rifle. The rifle is readily disassembled into two assemblies for storage or ease of transporting, without requiring any separable fastener. A supply of ammunition is carried in a hollow stack tube. Both a rimfire embodiment and a centerfire embodiment are disclosed, and stampings or other relatively inexpensive and lightweight components are extensively used in both embodiments. | ||||||
| 147 | Portable firearm with a retractable barrel | US528392 | 1974-11-29 | US4016800A | 1977-04-12 | Maurice Rusbach |
| A portable fire-arm having a recoil brake braking the recoil stroke of the barrel relative to the breech-carrier when a shot is fired, which includes a manually operated mechanical connection device between the barrel and the recoil brake the whole being so arranged that the barrel can be manually retracted into the breech-carrier in the retracted carrying position, the brake being rendered inoperative. A device is provided for locking the barrel relative to the breech-carrier in that retracted position. | ||||||
| 148 | Safety system for handguns | US573023 | 1975-04-30 | US3979850A | 1976-09-14 | Alois Schiessl; Rudiger Van Acken |
| There is disclosed a handgun intended for one-time use for launching a projectile. The gun is stored in a condition wherein a handle of the gun is folded to cover the trigger. A releasable locking member locks the handle in its folded position. In its folded position, the handle biases a pair of knobs inwardly to prevent actuation of the trigger, while a portion of the trigger engages the firing pin to prevent movement of the firing pin. In the stored condition of the handgun, the firing pin is uncocked and is unable to be moved into a cocked position. The locking member has a guide portion which is slidable within a bore containing the firing pin and its biasing spring. The guide portion acts as an abutment and a guide for the rear end of the spring. In one embodiment of the invention, the locking member is cammed inwardly by the handle as the handle is unfolded, to automatically cock the firing pin spring. In another embodiment of the invention, the spring is cocked during actuation of the trigger, with the firing pin being automatically released after a predetermined movement of the trigger. A separate safety member can be provided to secure the firing pin against cocking movement even when the handle is unfolded. This safety member can comprise a rotatable bolt which is held against rotation by the handle when the handle is in a folded position. Alternatively, this safety member can comprise a slide which is held by a leaf spring in its safety and released positions, and which can be cammed to its safety position by the handle if the handle is shifted from an unfolded to a folded position. | ||||||
| 149 | Hand gun and ammunition therefor | US3729848D | 1970-09-17 | US3729848A | 1973-05-01 | WILHELM G; YELLIN M |
| A hand gun and a shot-type ammunition cartridge which provides a linear shot pattern. The gun includes a barrel which is pivotally mounted to the gun frame to fold the barrel against the frame for easy storage or for concealment under clothing. The barrel has a specially shaped bore which is oblong in cross section and a fanshaped muzzle to provide a planar field of fire when a shot-type gun shell is employed. A shell having a special configuration conforming to the shape of the bore cooperates with the barrel in developing an even distribution of shot in a linear shot pattern.
