Definitions

  • This invention relates to automatic firearms and has particular reference to a repeating shotgun of the type having a barrel and breech block adapted to recoil upon firing of the gun, and means for retarding the recoil movement of the barrel and then restoring it to its firing position.
  • the aim of the invention is to provide an improved firearm of this type having various features of novelty and advantage.
  • aims of the invention are to provide an easy and quick takedown whereby the barrel may be easily removed and replaced without detaching the forearm or other parts from the receiver; to eliminate the unsightly forearm screw cap; to improve the appearance of the forearm by diminishing its bulk and streamlining the same; to make the gun lighter by using lighter weight springs and friction devices employed to retard the recoil movement of the barrel; to provide strong and durable springs to retard the recoil of the barrel after a shot has been fired and return the barrel to forward position; to provide bufier means for softening the shock incident to stopping the forward movement of the barrel without causing a chattering or vibration of the barrel; to soften or deaden the shock which ordinarily results when the breech block reaches its 18 Claims. (Cl. 89-177) to that shown in Fig. 1.

  • Fig. 6 is a transverse sectional view taken substantially on line 6-45 of Fig. 4;
  • Fig. '7 is a rear view of the parts shown in Fig. 5.
  • the invention shown is embodied in a firearm having a frame or receiver ID, a barrel II, and a stock l2.
  • the barrel is provided at its rear end with a barrel extension l3.
  • the barrel extension as usual, extends through an opening in the forward end of the receiver.
  • barrel extension as used herein and in the claims is intended to mean and include the rear end or extension of the barrel which is associated with the receiver whether integral or formed as a separate piece, these being equivalent common alternatives well known in the art.
  • the receiver is provided with the usual ejection opening (not shown) in the side opposite The numeral l5 desigbarrel and having its rear end secured in the front end of the receiver, as by means of screw threads l6.
  • a breech block ll which may be of any suitable construction, the same being shown
  • a locking block (not shown) may be provided for locking the breech block to the barrel extension so that the same will recoil in unison upon firing a shell, whereupon the breech block will become disengaged from the barrel and complete its recoil movement while the barrel is returning to "battery. Then the breech block will be moved forwardly to its breech closing position, as by means of an action spring, also not shown.
  • the gun will also be provided with a carrier (not shown) for receiving a rearmost shell from the magazine and moving it into the barrel extension whereupon the advancing breech block will move the shell into the firing chamber of the barrel.
  • the numeral 20 designates the forearm which houses the magazine and which is slotted at its top so as to straddle the lower portion of the barrel.
  • the forearm adjacent its forward end, is provided with a bore 21 which closely receives the forward end of the magazine.
  • the forearm is secured to the forward end of the magazine by a screw 22, which threads into a plug 24 fixed in the forward end of the magazine.
  • the screw extends through the front wall 25 of the forearm and bettoms thereagainst.
  • the forearm is recessed as at 26 so as to accommodate the head of the screw, and this permits the forward end of the forearm to be nicely rounded or curved, giving it a streamlined appearance.
  • the rear end of the forearm straddles the receiver and is secured thereto in any suitable manner, as by means of screws 2:1.
  • Mortised within the forearm and engaging the shoulder provided at the rear end'of the bore 2! is a stop member in the form of a ring 28 against which a slide 29 is adapted'to abut.
  • a block or member 30 Closely encircling, but slidable on, the rearend of the magazine and adapted to abut against the forward end of the receiver is a block or member 30.
  • any other suitable support for the block or member 312 may be utilized, such as a guide rod or the like, in the place of the magazine.
  • This block serves to carry the takedown latch 32 and the takedown lever 33.
  • the same being respectively disposed on opposite sides of the magazine adjacent the upper edge thereof. They are housed within the forearm. These springs are of relatively small diameter but are relatively stiff so as to properly retard and cushion the recoil movement of the barrel.
  • the rear ends of the springs engage the front face of the block 36, and their forward ends engage against friction collars 3s.
  • the forward ends of these collars are tapered, and these tapered portions are .received by the tapered recesses 35 provided in the rear end of the slide 29.
  • the collars are split at one side, as at 35.
  • the slide comprises a relatively small piece positioned above the magazine. Extending through the springs and the friction collars are guide rods 38.
  • the rear ends of these guide rods are threaded into openings 39 in the block 36 so that relative movement between the guide rods and the block is prevented.
  • the forward ends .of the guide rods slidably extend through'the friction collars and holes in the slide 29 and into openings or bores 4
  • the guide rods have a relatively close Sliding fit in the bores 4! whereby their forward ends are properly supported and guided.
  • the forearm is provided with bores 42 aligned with the bores 44
  • the barrel is detachab-ly connected to the slide in such manner that, when the .takedown latch is moved to unlatched position, the barrel may be dismounted by merely drawing the barrel forwardly relative to the receiver.
  • the barrel between its ends, is provided with a depending lug 44 of inverted T-shape cross section, as shown most clearly in Figs. 4 and 6.
  • the slide is provided in its top with a groove 45 corresponding in cross section to the lug 44.
  • the forward end of the groove is open so that the lug may be inserted in the groove, in the act of assembling the barrel to the receiver, by aligning the lug with the groove and the barrel extension with the receiver and then moving the barrel rearwardly until the rear end of the lug engages the rear wall 46 of the groove.
  • the barrel extension has a bottom surface .or
  • the block 33 has a top surface .54 which is substantially aligned with the face 5
  • the block has a transverse groove 55 in its top wall and grooves 56 in its side walls for accommodating the latch 32 which is in the form of an inverted U-shaped piece.
  • suitable means for manually moving the same downwardly out of the way of the shoulder 52 when it is desired to dismount the barrel. This means, in the present'instances, is shown, for illustrative purposes, as comprising the take-down lever 33.
  • This lever has a curved yoke 51 pivoted between the lower ends of the arms of the latch, as by pins 58. Extending forwardly from the central portion of the yoke is an arm 59 having, on its forward end, a finger piece 5!]. The upper edges provided on the ends of the yoke 5! engage against a downwardly facing shoulder 6
  • the latch is .normally urged to upward or latching position by helical springs 62 carried 'by the block and bearing against the under face of the cross portion of the latch.
  • the barrel When a shell is fired, the barrel recoils, and due to the engagement of the rear end of the lug 44' against the rear wall d6 of the groove in the slide 29, the slide moves back with the barrel, thereby compressing the recoil springs and contracting the friction collars against the spring guides so as to retard the recoiling movement of the barrel. After the completion of the recoil movement of the barrel, the recoil springs force the slide 29 forwardly together with the barrel and thus bring the slide to rest against the ring 28.
  • the barrel tends to continue its forward movement after the slide has been brought to its forward position of rest, with the result that the shoulder 52 of the barrel extension will engage the rear edge of the cross portion of the latch 32 and, since the block may slide forwardly on the magazine, the springs come into 'play to cushion and limit the forward movement of the barrel and return the barrel to correct battery position.
  • the guides 38 are fixed to, and move with, the block 39, and these rods extend through the friction collars 34, the friction exerted by the collars against the rods dampens any tendency of the springs to rapidly vibrate longitudinally and thereby prevents chattering of the barrel.
  • the breech block is moved forwardly by the-action spring with a sharp movement against the rear end of the barrel, and this may cause some shock or jar. This shock is relieved because the barrel can yield slightly forwardly.
  • the recoil springs are of sufficient strength to alwaysreturn the barrel and breech block to :proper battery position.
  • the recoil springs are so located that the forearm need not be increased in width over what is necessary to properly house the magazine, which is not true of older structures wherein the recoil springs encircle the magazine tubes.
  • , together with their guide rods, are of materially less weight than is the usual recoil spring about the magazine, and thus the firearm is further lightened.
  • the springs effectively perform their functions.
  • the slide 29 is entirely supported by the guides or rods 38 which in turn are supported at their rear ends by the block and at their forward ends by the stop member or ring 28 fixed in the forearm.
  • the slide has a fixed line of movement longitudinally of the magazine, and the barrel, since it is connected to the slide so as to move therewith, is held against other than longitudinal movement.
  • the recoil springs not only serve to take care of the recoil and return movements of the barrel, but also cushion the forward movement of the barrel and the breech block.
  • the barrel may be removed without in any Way disturbing the rest of the assembly and, particularly, there is no necessity of dismantling the forearm for the purpose of taking ofi the barrel.
  • the barrel may be mounted by merely slipping it in place.
