Definitions

  • This invention relates to firearms of the type 1 having a barrel and a breech block adapted to recoil upon firing of the gun, and means for restoring the barrel and breech block to firing position.
  • An aim of the invention is to provide certain improvements in the take-down arrangement disclosed and claimed in my copending application Serial No. 605,773 filed July 18, 1945, now Patent No. 2,465,196, and entitled Self-Loading Recoil Operated Firearm.
  • an aim of. the invention is to provide an improved and simplified take-down arrangement without detaching the forearm while permitting of such a construction of foreblock I4 of suitable construction and with which may be associated a locking block (not illustrated).
  • the recoil spring It for returning the barrel after firing to firing position is positioned about the guide l and at opposite ends of this spring are friction pieces I! and I8 which serve the same general i purposes of the friction pieces or collars shown in arm that it will closely fit the lower half of the C barrel, thus eliminating unsightly openings or cracks through which dirt, Water, or the like might find access to the interior of the forearm.
  • My improved arrangement further permits the forearm to be of streamline appearance while, at l the same time, covering the barrel sumciently to protect the fingers of the hand gripping the forearm from coming into contact with the hot recoiling barrel.
  • Fig. 2 is a top plan view thereof
  • Fig. 3 is a view similar to Fig. l but'with the forearm in longitudinal section;
  • Fig. 4 is a view similar to Fig. 3 but with additional parts shown in longitudinal section;
  • Fig. 5 is a cross sectional view taken substantially on. line 5-5 of Fig. 4;
  • Fig. 6 is a cross sectional view taken on line 6--6ofFig.4;
  • Fig. 7' is a perspective view of the forearm catch; and i Fig. 8 is a detailed view showing the forward end of the plate 58.
  • the firearm shown therein is generally similar to that disclosed in my said copending application. It has a receiver H), a barrel l which may have a barrel extension I2 extending into the forward end of the receiver, and a, stock I3. It is also provided with a breech my said copending application.
  • the rearmost friction collar I1 engages a block or member I9 which is here shown as being at the forward end of the receiver. This member carries the takedown latch '20 which is of the same general character as that shown in my said application.
  • the slide has a ring portion 22 slidably surrounding the guide and one end of this ring portion is conical so as to accommodate the corresponding conical end of the forward friction piece I8.
  • the slide proper has an undercut groove 25 open at its forward end so as to detachably accommodate an inverted T-shaped lug 26 depending from the under side of the barrel.
  • the parts upon the guide are held together and the compression of the spring is adjusted by means of a screw 21' having a shank screwed into the outer end of the guide.
  • a washer 29 having two ears or lugs 30 extending from its rear face and-which-lugs engage in corresponding notches 32 in the end of the guide and notches 3!
  • the head of the screw is provided with a plurality of transverse openings 33 which are adapted to selectively receive a cross screw 34 which, as hereinafter explained more in detail, constitutes a pivot for the forward end of the forearm 35.
  • a cross screw 34 which, as hereinafter explained more in detail, constitutes a pivot for the forward end of the forearm 35.
  • the take-down latch 26 is in the form of an inverted U-shaped piece having legs 45 engageable in grooves 4
  • the latch 25 when in raised or operative position, cooperates with a forwardly facing shoulder 45 on the barrel in order to prevent the barrel from moving forwardly out of the receiver. This shoulder is shown, for illustrative purposes, as being at the forward end of the barrel extension.
  • the forearm 35 has a longitudinal recess 50 which houses the guide and the parts carried thereby.
  • the barrel as is usual, tapers down in diameter as it progresses from its rear end.
  • the forearm is slotted at its top and the slot 5i is tapered, the taper corresponding to that of the barrel so that the upper edges of the forearm conform to and closely engage the barrel for a substantial portion of its under side.
  • the arrangement is such, however, that there is normally sufficient clearance between the barrel and those portions of the upper edges of the forearm forwardly of the pivot 34 to permit the rear end of the forearm to swing down in a manner now to be described.
  • the barrel is removable from the receiver by merely pulling the barrel forwardly after the take-down latch is disengaged.
  • the forearm since the forearm conforms to the barrel in the manner just stated, in order to permit such removal of the barrel, the forearm is moved slightly with respect to the receiver and, by preference, this movement is employed to actuate the take-down latch.
  • the forearm has a limited pivotal movement for this purpose.
  • the forearm 35 is pivoted on the pin or screw 34 which extends through one of the openings 33 in the screw 21 carried by the forward end of the guide.
  • the extreme rear end of the forearm is formed so as to straddle the forward end of the receiver.
  • the forearm has a metal insert 52 which straddles the block l9 and latch 20 as shown most clearly in Fig. 5.
  • the insert has, at each side, an upwardly facing shoulder 53 and these shoulders are adapted to engage the lower ends of the arms 40 of the take-down latch to hold this latch in latching position when the forearm is held up by a forearm catch 55 in normal firing position.
  • the insert further has adjacent its upper end downwardly facing shoulders 56 which are adapted to engage the upstanding lugs 44 of the takedown latch when the rear end of the forearm swings down upon being released from the forearm catch 55 so that the forearm assists in moving the take-down latch downwardly out of barrel latching position.
  • a spring pressed plunger 5'! normally tending to urge the rear end of the forearm downwardly.
  • the forearm catch 55 is shown as being in the form of a slide mounted in a T groove 62 in the side of the receiver at the forward end thereof. Closing the bottom of the receiver is a plate 58 having at its forward end a slot 59, the rear portion of which is of reduced width. The rear end of the forearm catch is transversely slotted, as at 63, so that the rear portions of the catch straddle the plate to either side of the narrow slotted portion 59.
  • the catch is normally urged forwardly to holding position by a spring 60 10- cated in a small bore 64 at the central portion of the slot, and the rear end of this spring engages the rear end of the slot 55.
  • the under side of the catch is roughened and constitutes a finger piece by means of which the catch may be readily drawn back out of forearm holding position.
  • Such downward movement of the forearm also removes the forearm from the line of movement of the barrel so that the barrel may now be removed by merely drawing it axially in a forward direction.
  • the upwardly facing shoulders 53 engage the lower ends of the legs 40 of the take-down latch and move the latter to the latching position shown in Fig. 5, and the forearm catch 55, under the influence of the spring 6
  • the forward end of the forearm catch is bevelled, as at 6!, so that, when the forearm is moved upwardly to normal position, the catch is cammed back out of the way.
  • a section having a receiver and a forwardly extending barrel guide, a barrel mounted for reciprocation with respect to said receiver and disengageable therefrom by a longitudinal movement of the barrel forwardly from the receiver, a slide supported for limited sliding movement longitudinally of the guide, a recoil spring urging said slide forwardly, means interengaging said barrel and slide when the barrel is engaged on the receiver and disengageable when the barrel is moved longitudinally therefrom, releasable means for preventing longitudinal movement of the barrel forwardly of the receiver, a forearm, means for mounting said forearm on said section for limited movement relative thereto from a position closely adjacent the barrel to a position somewhat removed therefrom, and interengaging means between said forearm and releasable means for operating the later upon said limited movement of the forearm.
