AUXILIARY DEVICE FOR PISTOLS Filed June 16, 1933 in 1 which has bars b' produced by stamping, on which the rear of the barrel a can rest and thus secured against premature sliding downward out of the sleeve under the action of the forward thrust, that is before the barrel reaches its abutting position.

In Fig. 4 of the drawing the sleeve b is extended towards the front forming a roof surface and this extension is bent downwards. The inclined plane thus formed presses the barrel downwards and thus facilitates the removal of the pistol under the sleeve during the pulling back of the barrel a;

up to its abutment point andliberatingof the barrel by the spreading of the claws 'grippinglover 1 the front thereof, owing to the further forward thrust. I I a Instead of the sleeve 1) surrounding the barrel it is evident that some other element operating in a similar manner may be employed, for'example,

an element holding the barrel along a portion of its rearwardmovmeht, which element liberates the barrelafter it has travelled 'a certain prede-- termined distance of its rearward movement. A suitable element for this purpose is for. example a resilientlclaw suspended on the carrying belt and which engages in a recess in the rear portion of the barrel or of a gripping claw having two crossed claw fingers which engage from both sides in an eye. mounted on the rearend of the barrel.

These elementsspread under the action of the forward or downward push so thatthe barrel is pulled back until it abuts and during the further thrust yield, move apart and thusliberate the 7 barrel by disengaging from the recess or laterally from the ,eye and allow thelbarrel'to again slide the barrel m. In the same manner as that above described the claw fingers 2', disengage from the eye when a forward thrust is exerted on; the pistol according to'their'degree of ;resiliency. in order;- during the pushing forward of the weapon, torelease'the charging carriage and render the loaded cocked weapon ready for use.

I a m:-.-

.1. An auxiliary d vice for loadingand cocking automatic'pistols, comprising a claw-like element of resilient material attached to the carrier belt and having edges resiliently engaging the barrel of the pistol, said element adapted to pull back said barrel against the spring action to load the pistol and to automatically disengage after the barrel has been pulled back a certain distance by said element, the resiliency of said claw-like element being greater than the strength of the spring action of the barrel;

2. 'An auxiliary devicelfor automatic loading pistols, comprising in combination with the barrel Z-ofthe pistol, a cap-like elongated sleeve open at thebottom, and at its front end and made of res'ilientrhaterial, inwardly bent claws on the front ;end ofsaid sleeve engaging over the muzzle of the barrel and adapted to pull back said barrel to load barrel'has been pulled back a certain distance by said element, and elements on the rear end of the said sleeve for attaching the same to a carrier belt and adapted'to exert a pull on said sleeve.

' 3. An auxiliary device as specifiedv in claim 2,

in which saidsleeve is split'in longitudinal direction at its front end. i

4. An auxiliary device as specified in claim 2, comprising in combination with the 'barreland the sleeve, bar-shapedguides on the rear end of said sleeve adapted to allow said barrel to pass out 'of the aperture on the lowerside of said sleeve only when said barrel has shifted back the predetermined distance.'-

5. An auxiliary device'as specified in claim 2, comprising" in combination with the sleeve, a roof shaped portion on the front end of said sleeve and inclined towards'the' axis .of said barrel to form extensions "descending 1 towards the barrel axis. ,7 I a +6.. An. auxiliary -device'for automatic loading pistols, comprising in combination with the barrel, said barrel having recesses adjacent its rear end, a claw composed of resilient expansible fingers adapted toen'gage in said recesses and to automatically disengage' 'fro'm said barrel after the same hasbeen 'pulle'd rearward a certain distance by'saidclaw. j I

7. An auxiliary device for automatic loading pistols, comprising'in combination with the barrel, an eye on the rear end ofsaid barrel, and a claw composed of two resiliently spreadable fingers adapted to engage in said eyeto'pull'back said barrelto' load the pistoland to move. apart and automatically disengage from said barrel after the same has been pulled back a certain distance bysaidclaw.
