:T0 allwhom itmmg concern;

Be it known that I, J ENS THEQDORSUHR SCHOUBoE,'-'first lieutenant a subject ofthe The present invention refers to a recoil mechanism in self-loading pistols with-fixed barrels characterized thereby that the breechblock is in one piece with a- U-shaped receiver,-

King of Denmark, residing at Rungsted Ladegaard, Rungsted, Denmark,'have invented a new and nseful Recoil Mechanism in Self- Loading Pistols with Fixed Barrels, of which the following isa specification.

which during-the backward and f or-ward movement of: the breech-block completely covers thelock mechanism and at the same time, to: gether with a closing-piece,'forms the connection between the main parts .of the pistol;

* the said receiver being inside supplied. with grooves-which gear partly with projections in the barrel extension firmly connected with the barrel and which in its turn .inknown manner is connected with the handle and partly with projections on the closing-piece,

which is forced rearward by the recoil-spring and held by hooks in the handle, while it at,

- the same time with its foot rests upon the top j is thereby kept in place. g

, The invention is shown on the accompanyof the rear end of the barrel extension, which ing drawings, wherein- Figure l is a vertical section of the entire mechanism. Fig. '2 shows the recoil mechanism and the positions of the various parts at the endof the recoil. Fig. 3 is a bottom plan view of the receiver, with the breech-block. Fig. 4 shows a section on the line 111 of Fig. 3. Fig; 5 shows a section-on the line IIY'II of Fig.3. Fig. 6 is a side view of the closingpiece. Fig. 7 shows a section on theline III arranged magazine 4, hammer .5, trigger ar- III of Fig. 6.

Fig.8 is an under side view of-the closing-piece. Fig. 9 is a bottom plan of the" breech end of the barrel and the barrel extension. Fig. 10 shows the back part of the cover and of the pistol with the closingpiece pressed inward, so' that the pistol can *bedismembered. l

. The pistol consists oi the barrel 1, firmly connected with the barrel extension 2, which in known manner is connected to the handle In thishandle there is in known manner rangemeut 6, and the appurtenant springs. 0n the sides of the barrel extension are ribs 7.

'Thehandl'e is in the'rear finished off with two breech-block is a borin for the firing-pin 1 1 and above this a boring for the recoil-spring 15. Thejiring-pin is held in place by a book 16, actuated by the recoil-spring or in any othersuitable way. That part of the recoilspring which lies outside the boring is guidedby a pin- 17, firmly fixed'in a closing-piece 1.8. This latter partise'e Figs. 6, 7, 8) has on the outer sides guides 19-,- corresponding to v grooves'20 inside the rear-end of the receiver.

(See Fig. 2.) The closing-piece is hollow, and

the foremost" end of this cavity has a rear-- ward projection 21, around which the hooks 8 will catch when the closing-piece is forced backwardby the recoil-spring. The closingpiecejends in front and below in a foot 23,

which bears against the upper part of the rear of the barrel extension, which thereby is kept in place. Ont'op of the receiver andin the rear is a spring-hook 22, which catches over the upper rim of the closing-piece,

thereby "preventing this from being thrown rearward by the recoil-spring [when the pistol is taken to pieces. This is done in this way that after the magazine having been removed the closing piece is with the right thumb pushed so much forward that the projection 21 shows clear of the hooks 8, (see Fig. 10;) whereupon the left hand presses down upon the barrel, which is made free, together with barrel-extension, breech-bl0ck with receiver, and closingpie'ce, so'that the receiver 9 can be disconnected from the bar rel and barrelextension. If it be desired to separate the weapon further; the hook 22 is raised .and the closing-piece and recoil sprin g can be removed.

' the chamber.

The recoil mechanism actsin the following manner: When the pistol is fired, the pressure of the powder-gas will force the breechblock and with it the receiver rearward, whereby the hammer is recocked, the empty cartridge-case ejected, and a fresh cartridge brought up from the magazine. The recoilspring tightened thereby will again force forward the breech-block, whereby the cartridge coming from the magazine is introduced into The pistol is now again ready for fire In order to cock the pistol for the first shot, the receiver is with the left hand carried backward and released when brought as far back as it will go. The sides of the receiver are therefore knurled on the outside. Having now described my invention, what I claim as new, and desire to secure by Letters Patent, isi 1. In a firearm, the combination with a frame and a barrel carried by said frame, of a receiver, a breech-block connected therewith, aclosing-piece at the rear of the frame, a spring between 'said receiver and closingpiece, said receiver being adapted to slide onthe frame, substantially as described.

2 In a firearm, the combination of the frame, a barrel carried thereby having an extension, a closing-piece resting on the extension of the barrel and the frame, a projection on the closing-piece,'a hook on the frame engaging therewith, a receiver, a breech-block connected therewith, a spring between said receiver and closing-piece, said spring keeping the projection and hook in engagement,said receiver sliding on the frame and closing-piece, substantially as described.

In a firearm, the combination with a frame and a barrel carried by said frame, of "a receiver, a breech-block connected therewith, a removable closing-piece at the rear of the frame, a spring between said receiver and closing-piece and tending to hold the closingpiece normally in position, the said receiver being adapted to slide on the'frame and closing-piece, substantially as described.

4. In a firearm, the combination with the frame and a barrel carried thereby, of a receiver, a closing-piece at the rear of the receiver detachably connected with the frame and a spring between the receiver and 010s ing-piece for holding the latter in place, substantiall y as described.

5. In a firearm, the combination with a frame and a barrel carried by said frame, of a receiver, a removable closing-piece at the rear of the frame, a projection on the closingpiece, a hook on the frame engaging therewith, said closing-piece having a portion outside of the hook and a portion on the inside of the hook and a spring for keeping the closing-piece in engagement with the hook, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
