Definitions

  • the present invention relates to slide action firearmssometimes referred to as pump guns.
  • a particular feature of the present invention is the provision of a novel take-down assembly.
  • a further feature of the invention is the provision of a slide action firearm wherein the forearm portion of the action is suspended in a novel fashion.
  • a further feature of the invention is the provision of a slide action firearm wherein the forearm while disposed in the actuated position, relative to the barrel, presents an exterior appearance which is entirely free of guide rods, rails, or tracks,
  • a further feature of the invention is the provision of a slide action forearm structure movable from a forward position corresponding a firing position to a rear position corresponding to an ejection position wherein the gun action is entirely enclosed within the forearm at both positions.
  • a firearm embracing certain features of the present invention and having novel take-down characteristics may comprise a barrel including a depending lug suitably connected to a receiver, a trigger assembly including a pair of spaced rails removably connected to the receiver and to the barrel wherein one end of the assembly engages the lug and the opposite end thereof engages the receiver, a slide arm assembly including a pair of slide arms carried by the rails and removably connected to the lug, a forearm rigidly secured to the slide arm assembly, said forearm cooperating with the barrel effective to enclose the slide arms so that when the forearm is moved from a firing position to an ejection position, the underside of the barrel is entirely free of guide rods and similar members.
  • FIG. 1 is a side view of a portion of a firearm embracing the principles of the present invention with certain portions thereof broken away for clarity;
  • FIG. 2 is an illustration similar to FIG. 1 showing the forearm in the ejection position
  • FIG. 3 is a view of the underside of the arrangement shown in FIG. 2 with the forearm removed, and,
  • FIG. 4 is a vertical section taken along the lines 44 in FIG. 2 showing the cooperation between the slide arm assembly and the forearm.
  • a receiver is shown in threaded engagement with a barrel 11 carrying a depending lug 12 formed with a pair of undercut circular grooves 13 and 14.
  • a trigger assembly 16 includes a trigger guard 17, spaced slide rails 1818, bridge member 19 and connector tab 21.
  • the rear or left end of the trigger assembly 16 is fastened to the receiver by means of a through pin 22 while the forward end thereof is secured to the barrel by the engagement of an elongated slot 23 formed in the tab 21 with the undercut groove 14 of the lug 12.
  • a bolt 24 is disposed in the receiver and is actuated in well known fashion by a slide arm assembly, indicated generally by the reference numeral 26.
  • the slide arm assembly comprises a guide portion 27 having an elongated slot 28 operative to engage and move along, in reciprocatory fashion, relative to the lug 12 wherein the guide 27 rides in the undercut groove 13.
  • the guide 27 includes a pair of opposed, upwardly flared wings 29 and 31 operative to engage corresponding ways '32 and 33 formed in a forearm 34.
  • the forearm is rigidly connected to the guide 27 of the slide arm assembly by means of a fastener 36.
  • the forward portion of the forearm is supported by the fastener 36 While the rear portion thereof is supported or carried by the cooperation between the flared wings 29 and 31 and the Ways 32 and 33.
  • the bridge member 19 of the trigger assembly is received within and guides the forearm while the slide arm assembly is driven to the left as viewed in FIGS. 1 and 2 to move bolt 24 from a closed position to an open position.
  • connection between the bolt and the slide arm is accomplished by the cooperation between a saddle 37 bridging spaced slide arms 3939 (only one shown) and a corresponding notch 38 cut out of the bolt.
  • the forearm may be removed to the right relative to the guide 27 to withdraw it from engagement with the flared wings 29 and 31 of the slide arm assembly.
  • the next step is to tap out the pin 22 releasing the left end of the trigger assembly from the receiver.
  • the slide arms 39 Upon removal of the trigger assembly, the slide arms 39 are free to drop downwardly a sufficient distance to permit disengagement between the bolt 24 and the saddle 37.
  • the bolt 24 is formed integrally with the slide arm assembly 26 and the enlarged opening 44 is located at the point designated 44' in FIG. 1.
  • the take-down steps are varied so that removal of the combined bolt and slide arm assembly is effected by sliding the combined assembly to the ejection position.
  • the enlarged opening 44 permits the right end of the assembly to drop clear of the lug 12 and the combined bolt and slide arm assembly is then drawn to the right and removed.
  • the firearm is assembled by reversing the steps just described.
  • a slide action firearm including a barrel having opposed ends, a trigger assembly and a receiver, a forearm movable relative to the barrel from a firing position to an ejection position, said trigger assembly being removably secured to the receiver and to the barrel, said trigger assembly being suspended and supported at a point on the receiver and at a spaced point located between the ends of the barrel, a slide arm assembly carried by the trigger assembly and keyed to the barrel at said spaced point, said slide arm assembly being movable in reciprocatory fashion relative to said trigger assembly and relative to said barrel, said forearm secured to said slide arm assembly and cooperating with the barrel to enclose the slide arm assembly so that when the forearm moves from one position to the other, marginal regions surrounding the barrel are entirely free of obstructions or protuberances.
  • a slide action firearm having desirable takedown features comprising a barrel having a depending lug, a receiver, a slide arm assembly operable to engage the lug and move relative thereto, a forearm connected to the slide arm assembly and movable in reciprocatory fashion along the barrel in company with the slide arm assembly, a trigger assembly including a pair of spaced rails operative to provide a track for the slide assembly and a guide for said forearm, said trigger assembly being connected at one end to the receiver and at the other end to said depending lug, said slide arm assembly 'having flaring side Walls operative to cooperate with and engage mating recesses formed in the forearm to provide support for the forearm.
