' AUTOMATIC FIREARM original Filed Jan. 25, 1954 O 33 37 as o 32 27 28 8 11 39 9 fof' so l lll/11.01111 w14 |:,|'l:\ :x ffffff 6 Patented Sept. 20, 1938 UNITED 4 s'xrAfrE-s PATENT `.OFFICE AUTOMATIC FIREARM Original .application January 25, 1934, lSerial No. 708,305. Divided and this application July 6, 1936, `Serial No. 89,046. -In Switzerland February 10, 1933 i 5 Claims.

The invention relates to a new and improved .automatic lire-arm of great firing power as `described in the co-pending patent application Serial No. 708,305 Patent No. 2,052,287 Vof which the ,following is .a ldivisional application.

vThe main object of the invention consists in `the provision of an .automatic re-arm being suitable for transport and-capable of being quickly set ready for action.

`A further object is the provision lof a magazine arrangement rfor fire-arms which is reliable .-andof simple mechanism and operation.

The magazine according to this invention is `provided with a large pivoted or detachable box magazine which 4for use of the nre-.arm is placed .into the charging opening .of fthe rire-arm in a position substantially at right angles to the barrel while, when the nre-arm is not required for use, the magazine is placed into a .position substantially in a plane parallel to the barrel in front of or behind the charging opening but `directly adjacent 4the latter; rIhe characteristic feature of the linvention is that the fire-arm and box magazine Aare so .constructed that the magazine is housed in ythe stock of the fire-arm.

The increased firing power of an automatic fire-arm necessitates ka large interchangeable magazine. The want of handiness .in transport `hitherto `caused thereby is obviated as the .magazine .is pivotally or `detachably mounted on the fire-arm .and is .adapted to be folded rinto the stock when not in use.

The invention will now .be described with reference to the accompanying `drawing wherein:

Fig, 1 shows a fire-arm in section with the magazine Yin -the position when the re-arm is required for use.

Fig. 2 shows the fire-arm with the magazine in the inoperative position.

Fig. 3 shows a second example of construction of the fire-arm.

As shown in Fig. 2 the magazine I9 when not required for use lies along the barrel l and the stock 21 of the weapon. The length of barrel is such that it extends beyond the front portion 29 of the stock 21 which receives the magazine I0. The magazine IIJ, which by means of the bush 9 rocks about the pin 8, ts snugly into a recess in the stock 21 in the swung-in position (Fig. 2) lying approximately parallel to the barrel I, the portion 29 covering it at the front. The magazine I0 is easily interchangeable. By corresponding replacement of the barrel I, bush 9 and magazine I0 the nre-arm can be used with cartridges of different calibres, e. g. 7.63, 7.65 and 9 mm. 'I'he magazine is held in V.the recess 28 by a cover 3l] pivoted :at 33. The cover 39 is provided with two side-,pieces 3l which, when the magazine is in the operative position partly embrace this and when 'the magazine vis Ain the inoperative ,position serve, together with the cover 30, to close the charging opening completely. The cover is `pressed into the closing position by a spring 32.

In Fig. 2 the fire-arm vis shown with open breech and at safety. When the safety catch 34 is moved to the release position (position F, Fig. 1), it rotates about its axis 35 and pushes a cover bar 31, pivoted thereto at 36, .towards the magazine. During this movement the bar 31 engages a projection 38 on the cover `30 Ithus rocking the latter downwardly and releasing the bush 9. The latter drops under the action of .gravity or of a spring, not shown, together with the `magazine IIJ rocks about its pivot'8 opening the cover 30, and assuming the .position shown 'in Fig. 1. In this ,position the bush 9 engages with a hook 39 on the cover 30. By moving the safety catch 3'4 from safe (positions) to re (position F) the rifle is ready for firing.

The empty magazine I0 may be replaced read ily by a full one. The magazine I9, when the safety catch 34 is in the position `S safe, may be left )in the extended operating position or Abe rocked intothe r'ecess28. For the'latter purpose, the cover 30 must be drawn slightly backwards so Vthat its Ahook 39 releases the bush. When the bush has been moved into 'the recess 28, the upper end is .engaged by the cover 3U, Athus locking it. "This locking, however, cannot occur until 'the vsafety catch 34 has been moved to the ,position "S vsafe, When themagazine `is lin the recess 28 it is retained by the locking pawl H and cannot be disengaged accidentally, so that the magazine I0 cannot be lost.

When it is not desirable to make the cover 3U dependent on the position of the safety catch, or if the safety catch is arranged in such a manner that the cover 39 is independent thereof, the cover bar 31 may be omitted. The side pieces 3| of cover 30 serve as a grip to facilitate moving the cover 30 which can be moved independently of the safety catch 34.

In the example of construction according to Fig. 3, when the magazine IIJ is not required for use it also in this case rests in a recess 28 of the stock. One end thereof rests on a support 4I secured to the portion 29 while its other end is engaged by a projection on the locking catch ll.. When the magazine is to be placed into the 30 in the example of construction shown in Figs. 1 and 2.

VA cover may be tted in a similar manner to the previous arrangement but simply for. closing the magazine opening. The arrangement according to Fig. 3 has the advantage that in addition to the long magazine I0 in the recess of the stock, a short magazine 49 may be tted into the bush 9 as shown by dotted lines, without aiecting the portability of the rifle. Independently of the position of the safety catch and breech block, this short magazine may be replaced by the long magazine and placed into a recess in the butt of the stock when not required for use.
