FEED MECHANISM FOR MAGAZINE-GUNS.

SPECIFICATION forming part of Letters Patent No. 518,821, dated April 24, 1894.

Application filed July 24, 1889. Serial No. 318,576. (No model.) Patented in France May 26, 1885, lie-169,154; in Belgium June 3.1885-N0. 69,114: in Italy June 30, 1885, No. 356; in Germany September 5, 1886,110. 39,960; in England Novemberl5, 1886, N0.11,815, and in Austria-Hungary January 2'7, 1887, No. 124.

T0 a ZZ whom it may concern:

Beitknown thatI, FERDINAND MANNLIOHER, a sub ect of the Emperor of Austria-Hungary,

and a resident of Vienna, in the Empire of- Austria-Hungary, have invented certain new and useful Improvements in Magazine or Bepeating Firearms, (for which I have obtained Letters Patent in Austria-Hungary, dated J anuary 27, 1887, No.124;in Belgium,dated June 3, 1885, No. 69,114; in France, dated May 26, 1885, No. 169,154; in Italy, dated June 30, 1885, N0. 356; in Germany, dated September 5, 1886, No. 39,960, and in England, dated November, 15, 1886, No. 14,815,) of which the following is a specification.

This invention relates to magazine or repeating the -arms in which the cartridge clasps, each containing a certain number of cartridges, are inserted from above into a permanent or fixed magazine arranged below the breech. On closing the breech, the breech block or plug engages with the uppermost cartridge and carries the same into the barrel. When the cartridge clasp is emptied, it has, in the firearms as heretofore constructed, to be ejected from the fixed magazine by a movement of the hand before a fresh cartridge clasp can be inserted.

The object of this invention is to so construct the cartridge clasp, fixed magazine and cartridge feeder or conveyer, that when the cartridge clasp is emptied it falls from the fixed magazine through an opening provided in the bottom of the latter.

I In the accompanying drawings: Figure 1 1s a longitudinal vertical section of the breech of a gun showing the cartridge clasp full of cartridges in position. Fig. 2 is asimilar view but showing the last cartridge raised to the top of the cartridge clasp. Fig. 3 is a similar View of a fixed magazine from which the cartridge clasp has fallen out. Fig. 1 shows a modification of the same. Fig. 5 is a per spective view of the cartridge clasp. Fig. 6 is an end view, and Fig. 7 is a section on theline p, q, Fig. 5. Fig. 8 is a side elevation, Fig. 9 a rear elevation and Fig. 10 a plan of a cartridge clasp designed to receive cartridges, the bottom flange of which does not project beyond the body of the cartridge; Figs. 11 to 13 show other modifications of the cartridge clasp in cross section.

In carrying this invention into practice the cartridge clasp B is made approximately in the form of a parallelogram, open at three sides, or in other words it is made of a strip of thin sheet metal bent to a U shape. Into this clasp the heads and part of the cartridge bodies are inserted, the other parts of the car-' tridges projecting through the open side B. The sheet metal of the said cartridge clasp B is bent inwardly at the top Z, Z and bottom Z Z so that the cartridges cannot fall or be jerked out through these parts, and suitable guiding grooves or indentations a a are provided in the sides of the clasp to impinge on the flanges of the cartridge heads, and to guide them during their upward movement.

The bottom of the fixed magazineAhas an opening mw at the rear and suitable projections or grooves M are formed on its sides for the proper guidance of the cartridge clasp B; within this casing is arranged an elevator consisting of a lever h (Figs. 1 and 2) pivoted on a pin 71 with a suitably arranged spring h attached thereto, and bearing against an arm k which is pivotally attached to the lever h and forms a rest for the cartridges, being held in contact with the same by means of the said spring h. The said lever h is also pushed upward by the action of a spring b.

When a full cartridge clasp is inserted into the fixed magazine, the cartridge elevator or feeder is depressed against the springs h and b as shown in Fig. 1.

In Fig. 3 I have shown a cartridge feeder, in which the arm it is dispensed with, the cartridges being lifted directly by the lever h. The bottom A of the fixed magazine is made removable, it being pushed withits one end between the sides of the casing and held in place by a screw A The end of the bottom A is cam shaped and fits into asuitable recess in the casing so as to efiectually prevent its turning when held in place by the screw A On this bottom A is fixed the spring I) which actuates the lever 71. pivoted to the bottom A.

The cartridge feeder shown in Fig. 4 is in all respects similar to that shown in Fig. 3 ex- I00 cept that the lever h* is made to rest loosely on the spring I) and to move in guides A A in the casing; the spring I) isin this case composed of two pieces of watch spring steel riveted together and having the lower end secured to the bottom A. It is obvious that in the devices shown in Figs. 3 and 4 the cartridge feed mechanism may be readily removed after unscrewing the screw A the bottom A can then be taken out from the casing together with the spring I) and eventually the lever h. The cartridge clasp is prevented from being ejected through the opening at the top of the fixed magazine by the elevator by a projection g on the cartridge clasp and a suitable catch 71 on a double armed lever H; and the inward bend Z Z of the upper edges of the cartridge clasp coming against the sides of the uppermost cartridge prevents the falling down of the cartridge clasp through the opening in the easing, the cartridges being held up by the before mentioned elevator h or 71*.

When the breech bolt or plug 0 is moved forward it impinges against the uppermost cartridge, the head of which is allowed to project slightly above the top of the cartridge clasp and is, in the path of the said breech block, pushed into the breech chamber O of the barrel, the grooves or indentations of the sides of the cartridge clasp a, a. being shaped as shown at u, u, to properly guide the uppermost cartridge in moving forward into the barrel. I attach to the said breech block 0 any well known form of extractor.

After the first cartridge has been fired, and the empty cartridge shell ejected by the backward motion of the breech block or plug 0, the elevator lifts the remaining cartridges in the cartridge clasp, so as to bring the second cartridge into the position which the cartridge fired had occupied prior to being pushed into the breech chamber, thus bringing its head into the path of the breech block 0, and thereby allowing it to be pushed into the breech chamber 0' by the forward movement of the said breech-block. Thus all the cartridges are raised, and each is pushed into the breech chamber and fired in turn. When the last cartridge is pushed from the cartridge clasp the latter falls by gravity through the opening m, x in the rear portion of the bottom of the fixed magazine A, the elevator It being adapted to pass freely between the upper inwardly bent edges Z of the cartridge clasp B.

When it is desired to remove a cartridge clasp not yet emptied it is only necessary to open the breech and to release the catch g (which prevents the cartridge clasp from being ejected through the top opening of the casing) by pressing the lower part D of the double armed lever H. The elevator then at once ejects the said cartridge clasp upward by its pressure against the cartridges contained therein.

Sometimes the cartridges are of a cylindrical form previously used by me, in which case the bottom flange does not project beyond the circumference of the body of the cartridge. The form of the clasps is in this case symmetrical and they can be introduced from both ends. This form of the cartridge clasp is shown in Figs. 8, 9 and 10.

The cross-section of the clasps or the width of their sides is optional; Figs. 11 to 13 show different forms which I propose to employ.

I claim as my invention 1. A cartridge clasp or holder for insertion with the cartridges into the magazine of firearms, struck or formed from a blank of elastic metal into a body open on three sides, having a rigid back and two elastic sides, the latter having their top edges slightly bent inward, and provided with straight indentations, parallel to the back, forming interior ribs suited to engage with the space or recess in front of the cartridge rims; substantially as and for the purpose set forth.

2. In repeating fire arms a magazine having a detachable bottom with the cartridge feeder or follower fulcrumed thereto and actuated by a spring, substantially as and for the pun pose described.

3. In magazines having a detachable bottom and the cartridge feeder or follower fulcrumed to the forward part of the latter, an opening in said bottom or left thereby large enough to permit the dropping through of an emptied cartridge clasp in the direction in which it was introduced into the magazine, substantially as and for the purpose set forth.

In testimony whereof I have affixed my signature in presence of two witnesses.

FERDINAND MANNLICHER.
