Be it known that I, J mm DOUGLAS Pensa- SON, of Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Recoil-Locks for Firearms; and" I do hereby declare that the following is a full, clear, and exact description of the invention,iwhich will enable others I skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form part .of this specification. 1

= simple in construction'and efiicient 1 and reliable in operation.

y In the drawings, Figure 1 shows, partially in side elevation, and partially in broken section, the frame portion of a firearm together with the breech-bolt and connected operating mechanism of a construction embodying the features of mypresent invention." 'Fig. 2 shows a longitudinal section takerton line'A B of Fig. 1 showing the parts below the seetion-line in one of the positions of the recoil lock. ,Fig. 3showsthe same section in another position of the recoil-lock. Fig. 4 shows a side elevation of the breech-bolt from the op posite side to that-shown in Fig. 1 in connection with a portion of the rear end of the cocking-head or firing mechanism and other Fig. 5 shows an edge view, andljig. 6 shows a plan view, of

the operative part of the catch or recoil-lock.

' Fig. 7 shows a side elevation, and Fig. 8 a

stated, is substantially of theforru of construcrear end view, of thecocking-head and firing pin. Fig. 9 shows a side elevation of the rear end of the operating-bar, and Fig. 10 shows the rear end view of the'same. Fig.

' 11 shows an end view, and Fig. 12 aside view,

of a-push and indicator button employed in the construction. i V

Referring to the reference-figures in a more particular description of the device, ,1 indi cates the frame of the firearm, which, as before rear end of the breech-bolt engaging with the rcoil-shoulder of the frame, as indicated at 3 in Fig. 1'.

For operating the breech-bolt there is pro-' vided the sliding action-bar 4, which at its forward end is provided with a sliding handle under the barrel in the usual manner and which is not shown in the drawings. At the rear end the sliding bar 4. is provided with a.-

fixed stud or projection 5, which engages in an angular slot 6 in one side of the breechbolt 2 and serves to give the vertical and I longitudinal movement to the breech-block when the bar 4 is moved backward and forward. The stud or projection 5 on the action oroperating bar as well as engaging in the cam-slot 6 of the breech-bolt also .engages with the plate-like portion? of the cocking-head on the firing-pin 7. The plate 7" operates in a suitable slot or recess-in the rear end of the breech-bolt, and the forward end or edge of this plate 7" is preferably curved, as shown at 7', to engage with .the stud or projection 5 of the operating-bar. "At

erating-bar there is provided a notch which afi'ords a shoulder 53"., sists of a lever pivoted to the breeclrblock at 9 substantially midway of its lengtlrand pro.- vided at one cm] with a stud or projection 8-,

The recoil-catch 8 conthe end of the stud of projection 5 of the opextending through a suitable opening in the body of the breech-bolt and having a tooth or catch-shoulder at its extreme end adapted to engage with the stud or projection 5 of the opder 5 thereof. on the other-end the recoilcatch 8 is provided with a spring-arm 8*,- V which is adapted to engage with the rear end of the cockiiig-head or more particularly with the plate iike portion-7" thereof when the firing-pin is in its retracted and cocked position. The tension of the spring-arm 8* of 9 erating bar and particularly with the shoul-f pressure on the operating-bar. done, the catch is then-released and the gun the recoil-catch when engaged with Ill? plate itorcan push on -the button 11, overcoming spring 8 by pressure, and thereby release the J reco1l-eatch, when the mechanism free to- 7, as stated, is to throw in the opposite and 0f .the catch so as to engage with the stud or projection' 5 on the operating bar. For throwing out same catch there is provided a spring 10, attached to the f rame at and carrying at its free end a push-button 11,which button engage; on the inner end with the rear arin of the recoil-catch andas to its outer end operates through an opening in the side wall of the frame.

- In aiming firearms of the construction de-. scribed having a sliding handle for operating the mechanism under the barrel the operator intentionally or unintentionally draws on this operating-handle to force the arm against the should .-'r, and were it not locked it would open the mechanism and place the gun in position where it could not be tired. It is to obviate this tendency more particularly that the recoil-catch described is provided, and the operation thereof is substantially as follows: Starting with the arm with the parts in position in which lheyare shown in Fig. 1 and which will correspond with the position immediately before firing the operator releases the firing-pin 7 by mechanism not shown except as to the sear 12. The firing-pin is impelled. forward'iby the spring provided for that purpose, as usual, and explodes the shell.

This also carries the forward cam or working face 7' of the plate of the cocking-head into its forward position, as shown in Fig. 2. Immediately prior to the firing the springarm 8 o-f the recoil-lock will be engaged with the rear end of the cocking-head plate 7 and force thercatching end 8" thereof into engage-' ment with the lock, notch, or shoulder 5 in the end of the stud or projection 5 on the opcrating-bar 4. Thus the operating-bar is locked'against rearward movement until such "time as the recoil-lock is released. \V hen the firing-pin moves forward, the spring-arm 8" is freed and the recoil-catchS would unlock' ;.under'the influence of the spring 10 except that the draw by the operator on the operating-handle of the bar causes such a friction between the recoil-catch and the shoulder on the stud 5 that it will not unlock under the influence of the spring 10 provided. If the gun by the operation of the spring 10. In case no explosion takes place upon releasing the .firingmechanism there will be no recoil, and

i the catch 8 will not become disengaged until the operator voluntarily releases the backward hen this is can be opened by moving rearwardly the operating-bar. In case it is desired to open the gun or operate the mechanism without firing 5 or operating the firing mechanism the operabe operated. The button 11, protruding from the side of the firearm, as shown in Fig; 3, serves as an indicator to the effect that the mechanism is cocked ready for firing. When the mechanism is operated'by the slidinghar -i, the breech-bolt 2 is first depressed and then moved to the rearward. At the same time the operating-bar stud 5 engages with the forward working end or cam-face 7 of the cocking-head on the firing-pin,' moving it back to cocked position, where it is caught by the sear 1-2. This will of course throw in the catch end of the recoil-lock when the breech-bolt is in a more or less open position.

Then the operating-bar: 4 makes the final part.

of its movementtoward the forward position, the end of the stud 5 engages witkthe catch end of the recoil-lock and thrcwsjtout sufficiently against the tension of the spring-arm 8 to allow the catch-shoulder 5 to come into engaging position with the recoil-lwk.
