Definitions
- This invention relates to improvements in a gun action for automatic, semiautomatic and manually operated guns and refers more particularly to that portion of the action mechanism which transfers cartridges from the magazine to the gun barrel.
- This transfer mechanism comprises a rotatable disk constructed to receive the cartridges singly in a slot or trough formed on one of its faces, and rotate them through a 90 angle in alignment with the barrel bore so they are successively inserted into the firing chamber with each actuation of the bol
- An object, therefore, of the present invention is to provide a simple positive mechanism for transferring cartridges from the magazine to the gun barrel.
- Another object is to provide a magazine in which the cartridges are arranged within an enclosure extending longitudinally or parallel with the gun barrel eliminating the necessity of an excessively strong spring necessary to support the weight of the column of cartridges as well as energy to feed the cartridges to the action.
- a further object is to provide a mechanism in which the operating parts are reduced to a minimum, are rugged and designed to withstand wear and usage over long periods without failure.
- Another object is to provide a gun action and magazine assembly permitting the use of pre-v loaded sealed dispensable containers for the cartridges wherein cartridges are charged asxa, unit in said preloaded container eliminating the necessity of filling a magazine with individual cartridges against the pressure of a strong magazine spring.
- Fig. 1 is a side view of an automatic gun provided with a gun action and magazine which embodies the invention.
- Fig. 2 is a top view of the gun indicating the position of the magazine extending parallel with the gun action and stock.
- Fig. 3 is an enlarged vertical section of the action.
- Fig. 4 is an enlarged horizontal section of the action and magazine.
- Fig. 5 is a view taken along the line 5-5 in Fig. 3 in the direction of the arrows.
- Fig. 6 is a view taken along the line 6-6 in Fig. 5 in the direction of the arrows.
- Fig. 7 is an exploded View of the action and. bolt structure.

- Fig. 9 is a reverse view of the disk from that shown in Fig. 8.
- Fig. 10 is a view taken along the line l0l 0 in Fig. 8 in the direction of the arrows.
- Fig. 11 is a perspective view of the dispensable container in which the cartridges are packed and loaded as a sealed unit into the magazine -seals port at perforations on three sides whenbroken by magazine follower and remain attached to the dispensable container.
- a gun stock having mounted thereon a receiver H and a barrel l2 threaded at its rear end to engage the internally threaded portion of chamber block 13.
- the barrel is bored and rifled to receive cartridges It, best indicated in Figs. 3 and 4.
- a magazine 15 with a loading port in its side for the introduction of cartridges introduced to the magazine in a sealed dispensable container 16, shown in Fig. 11.
- the port in the magazine through which the cartridge container is inserted has a closure plate I5a hinged at 1% and held shut by means of a spring latch I50.
- a knob led on the closure plate is an aid in opening and closing the loading port.
- the bolt mechanism comprises bolt block 2
- the bolt proper consists of an elongated rod, or cy1indrical member 22 threaded over a portion of its length as shown at 22a, to screw into the internally threaded portion of the bolt block.
- the forward end of the bolt, including the threaded portion, is longitudinally grooved at 221), as is the bolt block at Zia, to accommodate passage of the stationary ejector 23 upon reciprocation of the bolt.
- the ejector is attached to the receiver or outside case of the gun and trips the shell from the bolt after extraction from the barrel, as will be hereinafter described.
- the hole through the bolt block has a shoulder near the back upon which seats the rim of sleeve 24 enclosing the rear end of recoil spring 25.
- the sleeve has a rear closure Ma which fits into plate 26 at the end of the action. That portion of the bolt rearwardly of threads 22a is of reduced diameter and serves as a guide for the recoil spring.
- the rear end of the recoil spring abuts against the rear closure 24a and the forward end against a shoulder formed in the bolt 22, where the threaded portion of the bolt commences.
- Beneath the bolt and adjacent its forward end is an extractor 21 attached at its rear end to the bolt and having sufiicient resiliency to spring out and engage, by means of its hooked end, the rim of the cartridge prior to extraction of the cartridge from the barrel.
- Beneath the bolt block and rigidly attached thereto or forming an integral part of the block is the forwardly extending disk actuator 28.
- the front end of the actuator has an enlarged head with a shoulder for engagement with notches in the periphery of the transfer disk hereinafter explained.
- a firing pin 220 Positioned in a longitudinally drilled hole in the forward end of the bolt.
- a rearwardly extending plate 13a from chamber block I 3 is apertured to receive a stud or stub shaft 29a extending from one side of transfer disk 29, shown in Figs. 4, 7, 9 and 10.
- a stud or stub shaft 29a extending from one side of transfer disk 29, shown in Figs. 4, 7, 9 and 10.
- an arcuate slot 291 into which fits a pin or stop 30 mounted upon and extending outwardly from plate tea as shown in Fig. 7.
- Stub shaft 29a of the disk bears in the aperture formed in the chamber block and the disk has rotative movement through a 90 angle limited by the travel of the stop 38 in the arcuate slot 2%.
- the opposite face of the transfer disk from that abutting plate Isa has a groove r cartridge slot formed therein and extending diametrically across the face of the disk.
- Parallel ridges 2c and 29d extend across the disk and form the opposite sides of the trough or slot in which is retained the individual cartridges [4 as they are transferred from the magazine to the gun barrel.
- the ridge portion 290 is drilled to receive a detent 3
- the lower surface of the cartridge slot is tapered slightly, as shown in Fig. 8, to permit canting of the cartridge out of alignment with the firing pin to avoid accidental firing of the cartridge before it is injected into the barrel.
- This spring assures positive rotation of the transfer disk through its 90 cycle.
- the edge of the disk is grooved at 2%, as indicated in Figs. 3, 5, 6 and 10, to receive the disk actuator 28 extending forwardly from bolt block 2
- the edge of the disk is notched within the groove, as indicated at 29 and 299 in Figs. 3
- a sealed container preloaded with cartridges is inserted through the side port of the magazine with the follower l1 retracted.
- the front and rear ends of the dispensable container are perforated around the edges so the forward pressure of the follower disrupts or bends down the ends of the package and permits feeding of the cartridges forwardly through the magazine, as indicated in Fig. 4.
- the cartridge groove or slot in the side of the transfer disk Will be parallel with the gun barrel and in alignment with the bolt.
- Cartridges fed from the magazine through its forward restricted end arrive at the transfer disk in a position 90 from the axis of the gun barrel and at right angles to the groove in the face of the disk, as indicated in Fig. 4.
- Retraction of the bolt by means of bolt handle 35 shifts the bolt mechanism rearwardly retracting with it disk actuator 28.
- Shoulder 28a on the actuator engages notch 29) on the disk rotating it through an angle of 90 so the cartridge groove in the disk is parallel with the axis of the incoming cartridge.
- the force of follower spring 18 causes the cartridge adjacent the disk to enter the groove, as indicated in Figs. 8 and 10.
- the injector bolt 22b pushes home the car- 1.
