MAGAZINE FOR FIREARMS.

Application filed July 10,

To aZZ whom it may concern:

Be it known that I, BETHEL ABIEL REVELLI, subject of the King of Italy, residing at 57, corso Duca di Genova, Turin, Italy, have invented certain new and useful Improvements in Magazines for Firearms, of which the following is a specification.

This invention has reference to a system of feeding cartridges to machine guns with retaining lips and a follower or feeder and which offers the following advantages (a) A. fixed magazine, strong and not liable to distortion into which the cartridges can be introduced rapidly and accurately during the working of the weapon Without any inconvenience.

(7)) For the filling of the magazine I employ clips, holders or the like of light metal or cardboard or other cheap material or 1 may even use envelope fillers which may be used for an indefinite period of time.

(a) I avoid automatically operated mechanical filling devices, which as is well known, are the most delicate parts of a ma chine gun.

The magazine may be fixed to the weapon so as to be capable of being easily and rapidly detached for cleaning purposes, or for the purpose of emptying it when the breech is closed. The filling will be performed through a suitable opening in the movable breech by means of an envelope filler which can be used for successive fillings.

The accompanying drawings show, by way of example, a diagrammatic constructional form of the apparatus according to the invention.

Figure 1 is a longitudinal axial section of the magazine and the adjacent parts of the machine gun.

Figure 2 is a partial section on a larger scale,on the line 22 of Figure 1.

Figure 3 is a similar section to the one shown in Figure 1 the magazine being shown in the act of being filled.

Figure 4: is a partial section on the line 41- 1 of Figure 3.

Figure 5 is an elevation, partially in section, of the filler.

Figure 6 is a section thereof on the line (i 6 of Figure 5, and

Figure 7 is a section thereof on the line 7-4 of Figure 5.

Referring more particularly to the drawings, 101 indicates the magazine of the ma- 1923. Serial No. 650,665.

chine gun, consisting substantially of a box shaped like a parallelepiped closed at the top by a cover 102 (which may be integral with the box 101 as in the example illustrated, or removable) and provided at its inner or lower end with side flanges 108 and a front flange 1011. The side flanges 103 are adapted to work in longitudinal grooves 105 formed in the body of the movable breeclrlOS while the front flange 1041 is provided with a hole into which a spring controlled tooth 108 mounted in a recess in the movable breech, enters when the magazine is pushed over the loading opening of the weapon.

In the magazine is mounted the feeder 100 operated in the well known manner by the spring 110 and mounted to oscillate on the pivot 111 projecting outwards through the longitudinal slot- 112 and carrying on this projecting part a knob 113. in order to prevent dust or foreign bodies from penetrating into the magazine the slot 112 may be conveniently protected by a cover integral with the knob 113 or by any other appropriate means.

Underneath the mouth of the magazine are arrangedv in the body of the movable breech, two side blocks 11st forming an extension of the magazine and carrying at their lower ends stops for the cartridges. The said stops (see Figure 2) consist of pawls 115 pivoted in suitable slots 11'? in the blocks 1141 and caused to project towards the interior by plungers 116 pressed by springs 118 against the fiat face of extensions 119 of semicylindrical section integral with the said pawls. The plungers 116 and the core responding springs 118 are contained in holes formed lengthwise of the blocks 11 1. The slots 117 are formed so as to permit of the complete disappearance of the pawls 115 when the filler is introduced into the mega zine and to return and hold the cartridges when the filler is extracted from the magazine.

The feeder 109 carries at its rear a projection 120 which enters a longitudinal groove 121 formed in the rear part of the magazine, said projection serving to operate the cocking tooth 122 of the breech block 127 after the firing of the last cartridge. For this purpose there is mounted in the body of the movable breech a rod 123 one end of which projects into the lower part of the groove 121 while the other end is in contact with the cocking tooth 122 provided with a spring tootn 12% which brings back to the position of rest with the rod.

The magazine is filled by the filler 126 (see Figure This filler or clip (see Figures consists of a fork having a rear limb 128 and a front limb 129 provided with longitudinal grooves 130 and the bridge 131 on which the rows of cartridges 125 rest The curved portion 132 of the fork below the bridge 131 acts as a manipulating handle and is suitably shaped so as to otler an easy and convenient grip. The ends 183 of the lips of the

members

128 and 129 may be bent shown in full lines in Figure 6 so as to hold the rows of cartridges in place or the lips may be straight as shown by dotted lines in Figure 6 in the first case naturally the ends 133 must be provided with springs s0 as to resume their original position as soon as the last cartridges have emerged from the filler.

'lhe apparatus works as follows:

The cartridges having been placed in the filler 126 this latter is introducet into the loading mouth or openin of the weapon and pushed into the magazine against the action of the spring 110.

The filling may be facilitated by raising the feeder 109 by hand by means or the knob 113. During this operation the pawls 1 will be brought into contact with the sides of the cartridges and will be forced back into the slots 117 and *ill consequcntly not offer any obstacle to the introduction ot the filler When the row of cartridges has passed the pa-Wls, the filler may be withdrawn, the cartridges being held in the magazine by the pawls which, by the action of the plungers 116 again protrude from the slots 11?. During the firing of the gun the cartridges will be thrust one at a time in the well known way into the barrel, by means of the breech block, and the pile will consequently descend in the magazine guided in its movement by the feeder which being pivoted exerts uniform pressure on the head of the pile avoiding irregularities in the movement of the cartridges. When the last cartridge has been tired the projection 120 enters into engagement with the rod 123 which moves the tooth 122 into the cocked position so that the breech block stops in the open position in which it can be locked by any known device so as to allow the magazine to he refilled again.

When for any reason the magazine has to be emptiech this operation may be carried out by operating at the head or top of the magazine by taking off the cover 102 if it is removabla or at the bottom by detaching the magazine from the weapon. For this purpose the flange 104 is disengaged from as by the side biocl's for holding the cartridges in place after the clip has been withdrawin said pawls moving backward into inoperative position during the insertion of the clip; and means automatically locking the breech block in its open position when the l e has been fired.
