MAGAZIN E-PISTO L.

SPECIFICATION forming part of Letters Patent No. 520,666, dated May 29, 1894.

Application filed June 23,1893. Serial No. 478,551. (No model.) Patented in France August 3, 1892, No. 223,444, and in Belgium August 3, 1892, No. 100,800-

To aZZ whom it may concern;

Be it known that we, PnrRUs BLAOHON and ETIENNE MIMARD, both citizen of the Republic of France, and residing in St. Etienne, (Loire,) France, have invented a Pocket-Firearm, (for which we have obtained a patent in France, dated August 3, 1892, No. 223,444, and in Belgium, dated August 3, 1892, No. 100,800,) of which the following is a specification.

This invention relates to a firearm of the magazine or repeating type capable of being conveniently carried in the pocket and discharged with one hand. This weapon admits of successive shots being discharged with great rapidity and possesses great strength and simplicity of construction. It can be taken to pieces and put together again without the aid of any special tool, the parts being so constructed as to be capable of being connected and disconnected with great facility. And in order that our said invention may be fully understood we shall now proceed more particularly to describe the same and for that purpose shall refer to the several figures on the annexed sheet of drawings, the same letters of reference indicating corresponding parts in all the figures.

Figures 1 to 11 of the accompanying drawings illustrate all the constituent parts of the firearm separately. Fig. 1 shows in side elevation, vertical sections and in plan, the breech box. Fig.2 represents a vertical section, an end view and a side elevation of the stock-plate. Fig. 3 represents the movable breech block in side elevations, end views, longitudinal section and plan. Fig. 4. shows the firing pin, and Fig. 5 the ejector. Figs. 6, 7 and 8 are detail views hereinafter referred to. Fig. 9 shows the side closing plate, and Fig. 10 a sliding top plate. Fig. 11 represents a cartridge. Figs. 12 to 17 illustrate the complete firearm in the different positions for firing, safety, taking apart, &c., as hereinafter referred to. These figures also show the internal arrangement of the weapon and explain its action.

The grip or handle of the firearm consists of a species of breech box A, Figs. 1, 12 and 13, closed laterally by a lid or cover D and comprising a barrel B (Fig. 1) firmly attached by a screw, a chamber or receiver a for the movable breech block, a chamber b for the trigger action and a chamber 0 forming a cartridge magazine. The chambers 12 and c are separated by a partition d provided with two studst and t on which are supported springs R and B, Fig. 16, which constantly tend to thrust back the movable breech block 0. The rear wall of the breech box is notched or recessed to form a passage for the movable breech block and its guides. The upper side of the box is formed with an opening 0 for the introduction of the cartridges and the ejection of the shells. This opening can be closed by a sliding plate 0 provided with a projection or thumb piece 0 which is formed with a notch constituting the back sight. The box is also provided with sundry other notches, recesses, grooves, 850., connected with the action of the breech mechanism, or with the operations of putting the parts together and closing the breech as hereinafter explained. On a spindle passing through the chamber 1) there is a cam c, and a spring 7' engages with this cam in such a manner as to retain or steady it in either of the three positions into which it can be placed by manipulating a lever 19 arranged on the end of the spindle outside the box.

The movable breech block 0, Fig. 3, is formed by a block of prismatic shape provided at the head or front end with two claws c c acting as a cartridge extractor; the cen ter of this breech block, being cut away for the purpose, is occupied by the striker P (Figs. 4 and 16) which is acted on by a mainspring 10'. The under side of the movable breech block is provided with a longitudinal slot 0 in which the heel or detent p of the striker slides and the sides of this slot are provided with a notch and an incline c hereinafter described. The sides of the movable breech block present recesses c for the reception of an ejector (Figs. 5, 15 and 17) formed by two blade springs e and 6 attached to one yoke piece c rocking in a recess a formed in the upper part of the movable breech block (Figs. 3 and 16).

The movable breech block 0 is provided with a tube or socket C for the reception of the spring B (Fig. 16). This tube is screwed to a thrust or stock plate T, Figs. 2 and 16,

provided at its lower extremity with a tubular socket 0 receiving the spring R. The sockets C and C are each provided with a small projection a a bearing against the rear end of the breech case and acting as stops which limit the backward movement of the movable breech block.

Upon the cam e worked by the lever 19 there is'placed a collar f, Fig. 6, guided above and below the cam by rods sliding in guides in the breech box, Fig. 16, and being constantly pressed upward by a spring 0*. The upper partf of this collar acts as the nose of the scar and engages with the detent p of the striker while the projecting partf is situated opposite to a notch 0 Figs. 3 and 14, and can be pushed down by an incline 0 Figs. 3 and 17.

The ejector, Fig. 5, is provided in addition to the blade springs 6' 6 with a short arm 6 carrying a pin projecting into a groove g formed in the side of the breech box Fig.1 in the chamber or receiver a.

The magazine 61 of the breech box is provided with a vertically sliding elevator i, Figs. '7 and 16, acted on by a helical spring R Figs. 8 and 1G, bearing against the bottom of the magazine, its upward movementbeing limited by a projection 70, Figs. 1 and 16. A small projection It prevents the elevator from slipping out of the magazine. A slot Z in the side of the magazine enables the position of the elevator to be seen from the exterior so as to indicate the number of cartridges contained in the magazine. The side of the breech box is closed by a plate D Figs. 9 and 12, sliding in dovetailed guides in the upper and lower part of the box and corresponding exactly with the form of the latter. This plate is provided with a bolt or catch 0 pivoted at o and engaging with the notches m or 01, Figs. 1 and 15, according as the plate is partially pulled out (Fig. 14) or completely closed (Fig. 12). The tail of this catch is acted upon by the notch m in such a manner as to cause the catch to return to the closed position. A recess 15 formed in the plate T, Fig. 2, receives the projecting part of the catch 17 and maintains the plate D in the closed position when firing.

The action of the parts is as follows: The lever 19 is capable of being placed in three different positions, namely, the position for unloading and taking the mechanism to pieces, the safety position and the firing position all three indicated on the left hand side of the breech box as represented in Fig. 13. In the position for unloading and taking the lock to pieces indicated in Fig. 14, the collar f is in its lowest position so that the sear nose f is situated out of the path of the striker P which consequently cannot be held back or cocked. 'When the parts are in this position the weapon can be unloaded and taken to pieces without any difficulty or inconvenience. In order to unload it it is simply necessary to grasp the breech in the hand and press the palm against the plate T afterward releasing the latter which is moved back automatically by the action of the springs B and R. The forward movement enables the movable breech block to push into the barrel the cartridge situated between its front claws c c and enables the arms e e of the ejector to pass under the lower part of the rim of the cartridge as indicated in Fig. 17. The ejector is actuated by means of its arm 6 which comes in contact with the front extremity of the slot g in the breech box. In the backward movement, the cartridge is drawn out by the claws c c and the ejector throws it out through the opening 0 when the arm 6 comes in contact with the rear end of the slot 9 which has the effect of raising it. In order to take the mechanism to pieces it is sufficient to push up the small catch o and draw the plate D toward the outer end of the barrel, which plate then assumes the position indicated in Fig. 14:. During this movement of the plate D, the catch v is lowered again by the end opposite the hooked end coming in contact with the lower edgeof the notch m; and at the end of this movement of the plate D the hooked end of the catch 1: catches on the lower edge of the notch m. By again raising the catch 11 it can now be disengaged from the notch m so as to enable the plate D to be drawn completely out of the breech box. hen this plate has been removed the whole of the movable breech block and supporting plate can be removed by drawing them to one side. The movable breech can then be unscrewed from the plate T thereby relieving the striker. The ejector can be taken out in like manner and the collar embracing the cam can be taken out with the same facility as well as the cartridge elevator and its spring. No tool is required for taking the mechanism to pieces, this being extremely convenient and advantageous. When the parts are in position for firing the collar embracing the cam occupies an intermediate position indicated in Fig. 16, so that the nose f of the sear engages with the detent p of the striker. The latter is consequently held back or cocked when the movable breech block is pushed forward by the pressure exerted upon the plate T. While this movement is taking place a cartridge is pushed into the barrel and when the breech is completely closed the part j of the sear comes in contact with the incline c on the breech block (Fig. 17) which depresses it so as to disengage the striker which is then forced forward by the spring 19' and strikes the cartridge with sufficient force to cause it to explode. The extraction and ejection of the empty cartridge shell are performed as hereinbefore described with reference to the unloading. The ejected shell is immediately replaced by a fresh cartridge pushed up from the magazine by the action of the spring R In the position of safety the collar f embracing the cam occupies the highest position as ICO IIO

indicated in Fig. 15, so that the part f engages with the recess 0 in the movable breech block and locks the latter so that it cannot be moved by pressing upon the plate.

The loading of the weapon is a most simple operation. The sliding plate obeing pushed forward so as to expose the opening 0, the cartridges are introduced into the magazine point foremost through this opening and the trough or elevator is pressed down and compresses the spring R and the second cartridge introduced is retained by the arms of the ejector which now occupy the highest position. When the weapon is not in use the slide 0 is of course drawn back so as to cover the opening 0 and prevent the introduction of foreign matter into the breech action. With the same object the safety notch .0 may be arranged in such a manner that the breech is maintained closed and no space exists between the plate T and the breech box when the weapon is carried.

WVe do not limit ourselves to the particular shape or dimensions indicated in the drawings which may be modified according to circumstances Without affecting the principle of the invention. Any suitable metal may be employed in the construction of this firearm.
