Patent number: 4310982Abstract: A detent system for tubular magazine firearms serving the dual function of retaining the magazine spring within the magazine tube when the cap has been removed while also acting as a detent to keep the magazine cap securely tightened during normal use. A plastic member is provided with full and partial longitudinal slots which cooperate with indents on the magazine tube to facilitate assembly of the detent system within the tube. The slots and detents also cooperate to maintain the plastic member securely spring biased in a position so that serrated teeth along a peripheral end surface will intermesh teeth on the inside periphery of the cap in order to maintain the latter securely fastened to the magazine tube.Type: GrantFiled: February 26, 1980Date of Patent: January 19, 1982Assignee: Remington Arms Company, Inc.Inventors: Jack L.

Patent number: 4173278Abstract: A transport mechanism for feeding cylindrical or prismatic parts of discrete or indefinite lengths at a rapid rate and with accurate position control, through a work station for treatment by automatic inspection devices, part counters, roll printers, or other processing apparatus. A system of opposed belts and guides feeds the parts without rotation and without appreciable slippage at a uniform rate along a fixed feed axis, in such manner that the lateral relationship of the parts to the axis depends on their degree of conformity to a correct geometrical form. This facilitates the inspection of part form as well as dimensions, and improves the uniformity of other treatments. An arrangement of nip rolls driven at reduced speed separates discrete parts uniformly to ensure correctly-phased registration with inspection, rejection, counting, printing, or other treatment devices. The mechanism is readily adjustable to accept parts of different diameters or transverse dimensions.Type: GrantFiled: January 26, 1978Date of Patent: November 6, 1979Assignee: Remington Arms Company, Inc.Inventor: Erwin Reitter

Patent number: 4146007Abstract: A target throwing apparatus in which a revolving magazine having a number of stacks of targets is independently and fixedly supported relative to an oscillating target throwing housing. A cocking mechanism stops the throwing arm just before reaching the over-center position whereupon initiating of the next cocking cycle throws the target. A power train consists of three equal-sized gears mounted on three parallel shafts to throw the targets and to oscillate the housing. The magazine includes a ramp and cam mechanism by which the entire column of targets is lowered by gravity prior to having springbiased fingers engage the second target from the bottom and having the lower-most target fall onto a predetermined drop pad on a target launching plate, which pad location does not change regardless of the position of the oscillating housing and launching plate. A scotch yoke assembly is utilized in translating rotary shaft motion to symmetrical reciprocating motion to oscillate the housing.Type: GrantFiled: November 17, 1976Date of Patent: March 27, 1979Assignee: Remington Arms Company, Inc.Inventors: James M. Alday, Kenneth C. Rowlands

Patent number: 4127054Abstract: A magnetically-actuated latching device for use in a powder level inspection system known per se, in which a holding plate slidably supports a number of probes in a pattern similar to an array of ammunition cases in a loading plate, and the holding plate is lowered by an elevator mechanism to insert the probes into the mouths of the cases. The probes signal the level of powder in the cases by rising out of the holding plate to proportionate heights. The improvement involves the use of magnetic probes which, upon encountering low or missing powder charges, actuate magnetic latches to prevent the loading plate from being separated from the holding plate. The operator's attention is forcibly called to the presence of low powder charges by the necessity to release the latches with a hand-held magnet.Type: GrantFiled: October 26, 1977Date of Patent: November 28, 1978Assignee: Remington Arms Company, Inc.Inventor: Lanny L. Gully

Patent number: 4107983Abstract: A method for detecting the local and overall distribution of tension in saw blades involves elastically deflecting a properly-tensioned model blade, which is loose in the center, into a compound curvature in the form of a saddle, and adjusting the amount of deflection until the blade surface becomes flat and rectilinear along one of two perpendicular axes of the deflection. Any similar blade of unknown tension which is to be treated is then subjected to the same deflection, and inspected for rectilinearity along the same axis of deflection. Any regions projecting from this axis contain excess tension, and are designated for hammering to loosen them. The blade is rotated while the deflection axes remain stationary, so that the local and overall tension levels in the entire blade may be conformed to those of the model blade.Type: GrantFiled: August 8, 1977Date of Patent: August 22, 1978Assignee: Remington Arms Company, Inc.Inventor: Chester H. Dawson

Patent number: 4088057Abstract: A firearm recoil system that reduces the maximum recoil force felt by the shooter. The recoil force applied to the shooter's shoulder is interrupted by tapping off explosive gases produced by firing a cartridge and directing the gases into a gas cylinder to actuate a piston rearwardly and at the same time provide a forward force to the firearm opposite to the rearward recoil movement of the firearm. The rearward piston movement is slowed down by compressing air trapped within the cylinder and then venting the compressed air so that the remaining recoil energy in the piston is gradually phased out. This results in a substantially lesser peak or maximum shoulder force.Type: GrantFiled: December 3, 1976Date of Patent: May 9, 1978Assignee: Remington Arms Company, Inc.Inventor: Paul Nasypany

Patent number: 4038923Abstract: Expendable case ammunition of the type which is expelled as a unit through the barrel of a firearm and whose case separates from contained projectiles in flight, comprises a body and a cap, and may include a separate projectile container. These parts are made of a deformable material such as plastic, and are snap-locked together. The body has an interior transverse wall separating a projectile chamber from a propellant chamber, which is enclosed by the imperforate cap to permit the use of loose propellant and to protect against contamination and accidental ignition. An anvil is integrally formed in the propellant chamber wall to cooperate with an internal primer and a firing pin which penetrates the cap. A diaphragm region of the cap is ruptured by initiation of the primer, and the cap remains attached to the body during ignition of the propellant and travel of the ammunition unit through the barrel of the firearm.Type: GrantFiled: April 6, 1976Date of Patent: August 2, 1977Assignee: Remington Arms Company, Inc.Inventors: William T. Cole, Joseph P. Pavone, John J. Scanlon

Patent number: 4029530Abstract: Ammunition rim fire priming mixtures are commonly prepared by mixing normal lead styphnate, a sensitizer, such as tetracene, an oxygen donor such as lead nitrate, and a frictionator such as ground glass. This invention relates to such a mixture and to center fire priming mixtures which consist of lead styphnate, tetracene, inorganic fuels and barium nitrate and to a method of forming them and is characterized by the use of lead styphnate which is formed in situ by the reaction of a water wet mixture of styphnic acid and a lead compound such as lead oxide (litharge), lead hydroxide, basic lead carbonate, or lead carbonate. Important advantages of this invention are reduced cost, improved safety since it is unnecessary to prepare, precipitate, or separately handle pure or relatively pure lead styphnate and improved percussion sensitivity of the resulting mixtures.Type: GrantFiled: February 12, 1976Date of Patent: June 14, 1977Assignee: Remington Arms Company, Inc.Inventor: Joseph F. Kenney

Patent number: 4027531Abstract: A method and machine for hammering circular saw blades automatically, to correct uneven distributions of residual stresses, and distortions of the blade surfaces from true planes, so that the blades will run true. This operation has previously only been performed manually, by highly-skilled craftsmen. The saw blade is elastically deflected so that its normally-planar surface lies in a curved surface of a predetermined contour. A proximity sensor passes over the blade to detect deviations of its surface from the predetermined contour, which occur at points of uneven stress distribution or surface distortion. At such points, the blade is arrested and hammered until the fault is corrected.Type: GrantFiled: November 28, 1975Date of Patent: June 7, 1977Assignee: Remington Arms Company, Inc.Inventor: Chester H. Dawson
