To all 'whom it may concern: Be 1t 'known that l, RUDOLF BECKER, a

The invention consists in providing in.

connection with the breech arrangement a fork shaped slide, running the Whole length of the pistol and which is so arranged that it can only be drawn backward fromthe pistol.

This slide is fitted underithe fixed'barrel, on both sides of it, and it isfbedded mov ably7 under the breech block, in corresponding spaces cnt out of the handle.v rjhe slide prevents' the-breech block, which is inserted into the pistol case :trom the back end, from in -side view and as seen'froin above.

l beingsnch asitoprevent/the'cartridgefroin falling out. VIt also serves to form a part of the back divisional wall of the pistol. At its front end the slideris attached to a mov- Yable abutment for the closing spring, below the barrel, and in such a waygthat it can easily bel detached therefrom and so that when the slide is drawn back the abutment is also drawn back and the closing spring compressed. The spring bolt for the closing spring passes through this abutment, which is retained in its position by a lever when thev pistol is being taken to ieces or beingv put together again.v During t ose operations the closinw leverfis disconnected from the trigger. Means are also provided forcoupling the tiigger fork to the trio'ger so that when the pistol is being dismantled the' trigger may be readily detached from the trigger fork.

Gn the drawings the subject of the invention is shown in one of its embodiments by Way of example. g

Figure l is a longitudinal section through the pistol. Fig. 2 is a horizontal section. Figs. 3 and 4 show the slide in side View and as seen from below.` Figs. 5 and G show the abutment for the closing spring in horizontal section and vertical section; and Figs. 7 and 8 show the trigger forks, with catch, Fifr. 9 represents a view of the pistol with rtline slide withdrawn the position of the parts being fired. Figs. l0 to 24; are separate detail views of certain parts of the breech and tiring mechanism. i

The" self-loading pistol -has a. barrel 2 tlrnily secured to the handle 29. Under the barrel a fori; shapedzslide .1, which can nieve along in a straight line is fitted in corre sponding rests cut ont of the handle. A projection 4 on the back end of the slide fits exactly into a corresponding notch in the breech block 3; consequently when the breech block 3 is drawn back the slide is carried along with it. The slide l has hook shaped projections 5 on its front end and -on Vthe inner surfaces thereof which form detachable connect-ions for the slide with an abutment (i for the closing spring 8 lying under the barrel.v The slide l Vis taken oli' or drawn back from the pistol by drawing' back the breech block 3 simultaneously with the slide 1 and the abutment 6, and during this backward movement of the breech block, slide and abutment the main spring 7 and thestronger closing spring 8 compressed. If the breech block etc., are drawn far enough back the abutment 6 will be ized and vretained in position by a catch lever i 9 whichV is tted inthe handle 29.

lVhen the breech block is released it moves Jforward automatically along with the slide and the abutment Gis prevented from taking part in the forward movement by the catch lever 9 (see Fig. 9) which isv compressed upward and engages the front of the abutment 6. The forward movement ot the slide i disengages it from the abutment G, which isv held fixed in its position. By slightly pressing apart the ends of the rods of the slide it is easy to dranY the slide 1 oli' the pistol toward the bach. The catch lever 9 is under the pressure of the leaf spring l0,

the catch Il, and the trigger fork l2 (see Figs.- 7, 8 and 9) and, it vcomes into action only when the pistol is being taken apart and put together again.v After the slide l ment moves quickly forward against the,

front Wall of the handle. under the influence of the closing spring S. lVhen the abutment is held firmly inposition by the catch leico ics

ver 9, the part 11x of the catch or finger 11, the front arm of which holds the catch lever down, is out of gear with the recess 13'y ofv trigger 13 and consequently the pistol'cannot be fired. The abutment 6 for the closing spring has notches on both of its outer sides. These are intended to prevent the lingers slipping whencatching and drawing back the slide. The bolt 14 for guiding the abutgment and carrying and gulding the closing spring 8 must lie in such a way that its longer slope is always directed downward thls position is shownin Fig. 1) so as to prevent 4any jambing when the catch lever 15 9 moves upward. The breech4 block 3 is drawn out vbackward and then the nose or .projection 15 on the tiring pin 16 in the breech block 3 slides over the scar 17. The trigger 13 should be pressed during this operation so as to depress the sear 17 in the direction of the upper arrow (Fig. 1) and thus facilitate the sliding passage of the nose or projection 15 on the firing pin 16 over the sear 17. The main spring '7,-w-ith the guide pin 18, is fixed in -the breech block. The abutment 6 and the bolt 14, with the spring 8 thereon can 'be easily taken out by means of -an auxiliary pin which may be fitted into the hole 19 in the bolt 14; and

thenxafter the bolt 14 has -been slightly pusheddE rward to overcome thetension of the spring 8, the bolt, with the ,abutment and the closing spring 8, can be dra'wn side wise out ofrthe case.

Before the breech block 3 is removed from the pistol casing the main spring 7, for the sake of safety, must be brought to the position which it takes up, immediately after firing a cartridge, and this is accomplished 4G by pressing the trigger 13 so as to lower the back end ofthe scar 17 in the direction of the upper arrow (Fig. 1) so that the projection 15.0n the firing pin 16 is released from engagement with the back end of the scar 17 and it can thenI be moved forward under" the action of the main spring 7 to the position shown in Fig. 1, which is the position of the main spring 7 and firing pin 16 after the -firing of a cartridge. In this position the main spring 7 is not com ressed and the possibility of lts being hur ed from the breech block and thereby injuring someone is obvi- I ated. The main spring 7 is secured in its position in the firing pin 16 by a holder 21 (Figs. 19 and 20) which is provided with a notch 21" for ho ding the end of the guide pin 18. The holder 2l rests with its end 21a against ashoulder 20x of the rear arm ofa lever 20 whose front arm 20a is under the pressure of a spring 24 suitably secured in the pistol handle. The rear arm of the lever 2() nor- ,mally presses* upward under the action of fthe spring 24 against the lower end 21'1 of the .holder 21 and holds the sameby means ofthe shoulder 20", but the reai` arm of the 4to spring forward, while the firing pin 16 lever 20 may be pressed downward after the slide. l is withdrawn until the holder 21 is released from engagement with the shoulder 20x of the lever 20. In consequence thereof and by means of the compression of the main spring 7 the holder 21 is turned from the vertical position as drawn, into a horizontal position in which the main spring 7 lies free and the breech block 3 with its contents can be easily removed fronr the pistol casing. -75 The trigger 13 which is under the pressure of a spring 22 has an upper projection 13x which is adapted to engage with and act on vthe rear end 1lx (Fig. 7) of a catch 11 working in a slot in\the front of the trigger fork 12. The pin 23 of the trigger fork 12 (see Figs. 1 and 2) is under the action of a s ring 25 suitably secured in the pistol handle and `it is-caused to move in slots 26 (see Fig.

1) provided. in both side walls 27 of the 85 pistol casing. The catch 11 of the trigger forli is pressed, by means of the spring 10 secured to the fork into a recess 13y of the trigger, so that if the trigger is pulled the projection 13x is pushed against the rear end 90 11x of the catch 11 and thereby the trigger fork 12 is pushed forward. The fork 12 is placed in a recess made in the wall of the casing and it is movable longitudinally. In this manner the trigger fork 12 is coupled 95 with the trigger 13 and the spring 25 normally presses the fork 12 backwardfso that the pin 23 lies at the rear of the slots 26.

.When it is desired to lire a cartridge the lower end of the trigger 13 is pressed back 100 so that the upper projectingv part 13K is moved forward giving a corresponding forward movement to the trigger fork 12 until the pin 23 lies at the lfront of theslot 26 so that the pin 23 slides alopg below the ob- 105 lique front arm 17a (see Fig. 21) of the sear 17 and,lifts it, causing the rear end 17b of the sear 17 to drop in the direction shown by the arrow in Fig. 1 and allowing the nose or projection 15 of the 'firing pin 16 to be re- 110 leased from engagement with the back end of the Sear 17 thus causing the main spring 7 and firing pin 16 to spring forward so that the point of the firing pin strikes the percussion cap of the cartridge.

The working of the pistol is as followsz- To discharge the pistol seven times, a cartridge is placed in the barrel, and the magazine is filled with six cartridges and placed into and secured in the hollow handle of the pistol. Thereafter, the breech block 3 together with the slide 1 and abutment 6 are drawn back a certain distance against the action of the main spring 7 and the closing spring 8 until the nose 15 of the firing pin '16 has passed the scar 17 which is accomplished as soon, as a soft noise or click is heard. 'lhen the breech block 3 together with the slide 1 and abutment 6 are allowed on the top, while at the same time the next cartridge from the magazine takes the place of the discharged cartridge. At the same time the tiring pin passes over the sear in consequence of. the drawing' back of the breech block 3 obtained by the action of the gas-pressure until the projection engages the bach end of the sear 17 as before and in this manner the tiring pin 16 is again kept back by the sear 17, under compression of the main spring 7, while the breech block 3 moves forward automatically under the action of the closing spring 8. It is only necessary to press the trigger again to tire the next shot. l

In order that the fork .or Sear, or both, may be released from 'the influence of the trigger during the rearward movemento the breech block, the 'forward end of the catch 11 is arranged to come in contact with the abutment 6 when the latter is retracted by the recoil of the breech block, whereby the catch 11 is tilted on its pivot and the hole or portion 11X thereof is raised out of engagen'ient with the part 13X, so as to allow the fork 12 to flip back and the scar nose to riseunder the influence of the spring 25 and catch the tiring pin in its rearward position even though the trigger be still held back.

Each time `the breech block 3 together with the slide 1 and abutment 6 are drawn back after the firing of a shot, an empty cartridge case is thrown out of the pistol andthe discharged cartridge is replaced by a new one from the magazine. The cartridge is moved forward into the barrel during the forward movement of the breech block 'which movement leaves the main spring 7 compressed in readiness for the for ward driving of the tiring pin 16. The pistol is therefore ready for tiring again, 1invlnediately ait'ter every shot, the mechanism working very accurately and safely.

`When the pistol 1s taken to pieces, accin dental discharge must be prevented. This can be provided against by pushing back tl1c"abutnxcnt 6 and securing it in the rear lpdsition by means ot thecatch lever9, asy

shown in Fig. EL Inl this position the abut inent- G presses the catch 11 out ot the recess ',ljY/"ot the trigger 1%)v and consciplently ung j coiiples the trigger `11?;- roni its trigger forli 1Q, so thatcven it the trigger 1:; be pressed l the trigger forli:A 'and scar 17 cannot be operated and the main spring 7 and firing pin 16 cannot therefore be released to tire a cartridge.

When the pistol is being taken to pieces, after the slide 1 has been removed from the pistol, and when the breech block 3 and its contents, the closing spring abutment 6, with the spring bolt 1st and the closing springt?,

have all been removed, the trigger fork l12 with its catch 11 may be raisedout of their depressed seat in the casing by pushing o ut the trigger fork pin Q3 by aid ot' a suitable pressingpin; then the sear 17 and the catch lever 21 for the main spring, and finally thesupporting lever Q0 can be easily removed after the pins which carry or hold them havebeen pressed out. The two leaf springs 24, 25, also the trigger 13 and the catch lever 9, may easily be taken out, if necessary, after their pins have been pressed out. The pistol is fitted together again by going through the same operations as are necessary for taking it to pieces, butin the reverse order.

Having now fully described my invention what I claim and desire to secure by Letters Patent is 1. In a self loading pistol the combination of a removable breech block, a Afork shaped slide for supporting the breech block when drawn back, a closing spring under the barrel for automatically closing the breech block, a movable abutment in connection therewith, and catches on the slide adapted to engage said abutment so that when theslide is drawn back the abutment is alsodrawn back and the closing spring compressed. i 2. In a self loading pistol the combination ot a removable breech block, a fork shaped slide for supporting the breech block when drawn -baclcra closing spring under the barrel l:t'or lautomatically closing the breech block, an abutment in connection therewith,

'and a catch lever for holding the abutment back to allow of the fork shaped slide being withdrawn i 3. In a self loading pistol the combination of a removable breech block, a fork shaped slide for supporting the breech block when drawn back, a `closlng' spring for automa-tically closing the breech block, a movable abutment in connection therewith, a trigger, a trigger fork connected therewith, aspring catch for coupling the trigger to the trigger fork said catch being pressed out of engage-l ment with the trigger when the pistol-is being taken-to pieces to prevent accidental discharge at such times.

In testimony whereof I aix my signature.
