APPLICATION FILED DEC. 16, I9I9.

mwmwo ip n time r e JTOHN D. PEDEN, 0F d'ACKSON, WYOMING.

rrrtn e Specification of Letters Patent.

Patented (Pet. 12, t92t1 original application filed July 80, 1915, Serial No. 42,774. Divided and this application filed December 16, 1919. Serial No. 345,177.

T 0 all whom it may concern Be it known that l, JOHN D. PEDERSEN, a citizen of the United States, residing in Jackson, in the county of Lincoln and State of Wyoming, have invented certain new and useful Improvements in Firearms, of which the following is a specification.

This invention relates more especially to that class of firearms which is usually designated as small-arms, and a principal object of the invention is to furnish an improved grip-safety device particularly applicable to auto-loading and automatic pisto s.

One class of small-arms to which my present improvements are applicable, includes the auto-loading pistols having a gripstock, or handle portion of the frame or receiver of the pistol, adapted to receive a safety device which is operable by hand or compression.

improved auto-loadingpistol of this kind is described in my co-pending application (renewal) Serial No. 311689, filed July 17, 1919, and the improvements herein described are also illustrated in my said .prior application, but are not specifically claimed therein, Therefore for convenience of illustration, 1 have herein shown my present improvements as arranged and ap' plied to the particular kind of auto-loading pistol ,which is illustrated in the drawings of said application, to which reference may be had.

A feature of my invention is that it is a grip-safety device arranged to prevent dis charge of the firearm by locking the sear member and the firing member or hammer in firing position. and also,'where the firearm is provided with a sliding breech action comprising a firing-pin, by locking the sliding breech action to prevent contact between the firing-pin and cartridge, so that action of the firing member or hammer will not explode the cartridge.

Another feature of my invention is that it is provided with what I term a resisting and retracting member; One purpose of the resisting and retracting member is to move downward or retract a slidable member or controller when the firing member or hammer is moved from firing position to fired position, which slidable member or controller is in upward, or looking position when the firing member or hammer is in firing position, and thus locks the sear memher and firing member or hammer in firing position, and locks the sliding breechaction of the firearm, when the firearm is provided with a sliding breechaction, the slidable member or controller being held in such upward or looking position by the grip-safety portion of my invention. A second purpose of such resisting and retracting member is to engage said slidable member or controller, when the slidable member or controller is in such upward or looking position, and at the same time to engage, when the firing member or hammer is in firing position, a means for connecting the firing member or hammer to the main spring or firing spring, and thereby to resist or prevent movement of the firing member or hammer from firing position to fired position.

In the accompanying drawings, which illustrate an embodiment of my grip-safety a sliding breechactioncompnsing a firing- I pin, and provided with my grip-safety device, the grip-operable or grip-safety portion of my device being grip-compressed to unlock the slidable member or controller, the firing member or hammer being unlocked from the sear member by trigger action and moved to fired position, the slidable member or controller being in unlocking position, and the resisting and retracting member being in position whereby it has retracted or moved the slidable member or controller to unlocking position, or downward. v v

Fig. 2, is a fragmentary side view on larger scale than Fig. 1, partly broken away to show the details, of the rear portion of a pistol provided with my grip-safety device, the sliding breechaction being removed,

prior to movement of the trigger member to forward position.

Fig. 3, is a fragmentary side view, on substantially the same scale as Fig. 2, partly broken away to show the details, of a pistol provided with my grip-safety device, the sliding breechaction being removed, the grip-operable or grip-safety member not being grip-compressed and in position of safety, and thereby blocking the slidable member or controller in locking position, the firing member or hammer being locked in firing position by the sear member, the resisting and retracting member being in position which has permitted movement of the slidable member or controller to locking position, and is in readiness to act as a resisting member for the firing member or hammer to retain it in firing position, and the trigger member being in forward position.

Fig. 3 is a sectional detail plan'view, of the resisting and retracting member of my grip-safety device, on the line Zi -3 of Fi 2.

ig. 3" is a detail plan view, on an enlarged scale of the top portion of my gripsafety device as shown in Fig. 3.

Fig. 3 is a detail sectional view, on an enlarged scale, on the line 33 of Fig. 3, looking in the direction of the arrow.

Fig. 4, is a detail sectional view on the line 44 of Fig. 3, looking in the direction of the lower arrow and on an enlarged scale, the grip-operable or grip-safety member bein removed.

ig. 5, is a detail sectional view, on an enlarged scale, on the line 4-4 of Fig. 8, looking in the direction of the upper arrow, part of the front of the rear portion of the pistol being removed.

Similar reference characters or numerals refer to similar parts throughout the several views.

My grip-safety device comprises with the various parts of my device to be hereinafter described, a firing member or hammer H.

The firing member or hammer H is pivotally supported on the grip-stock of the pistol and is movable to firing position, and to fired position, the grip-stock of the pistol being bored out or otherwise suitably cut away to receive the firing member or hammer and the various other parts of my device.

The firing member or hammer H is provided with a firing-notch or cock-notch 8 The scar member S is pivotally supported on the grip-stock of the pistol and is provided with a locking-face 17 which is en-- gageable with the cock-notch 8 of the firing member or hammer H, and is provided with an end-face 17 d which is engageable with the' ing position, being, as shown,-movable upwardly and downwardly, and is guided at its upper end by guide-faces 10 and 11. The slidable member or controller is provided at its upper. end with an end 14? which is engageable with the sliding breech action. A slot 12 is provided in the slidable member or controller N to receive the end of the trigger member F and allow a slight movement or play of the trigger member therein. The slidable member or controller N has near its lower end ashoulder 14 which has an upper engaging surface or face 14 on either side of the slidable member or controller. The slidable member or controller N is provided, adjacent to and below the slot 12, with end-faces or bottom-faces 14. A spring actuated contractor 13 carried by the slidable member or controller N, contacts or engages the face 17 b of the sear member S to move the sear member inwardly, and thereby move the end-face 17 of the sear member forwardly for engagement therewith of the trigger member F. The slidable member or controller N is provided at its lower end with an actuator 14'. The actuator 14" comprises a stem or spindle 14 and a spring 15. The stem or spindle 14,'is rigidly attached at its upper end to, or may be integral with, the slidable member or controller. The stem or spindle 14 is seated in or extends through a member or boss 16 mounted on the grip-stock of the pistol, and thus, in addition to its function as a stem or spindle for the spring 15, provides by its at its upper end the lower side or face of the shoulder l4. of the slidable member or controller -N, the tendency of the spring 15 being to move or force the slidable member or controller upwardly.

The grip-operable or grip-safety member G is pivotally attached at its lower end to the rip-stock of the pistol by a pivot pin 9, pre erably in the manner described and set forth in my co-pending application (renewal) Serial No. 311,689, filed July 17, 1919. The grip-operable member G closes the space 2 in the grip-stock and is yieldable or hand compressible, the grip-operable or grip-safety member being, when in position of safety engageable at its upper end G with the frame of the pistol and releasable from this engagement by grip-compression. The grip-operable or grip-safety 7 member G is provided with locking-prongs ment between the rod and the cupped 7, which are engageable, when the grip-operable or grip-safety member is in position of safety, with the end-faces or bottom faces 1% of the slidable member or controller N, to block or retain the slidable member or controller in upward locking position, the grip-operable or grip-safety member being releasable from this engagement by gripcompression.

The main spring or firing spring 8 is seated at its lower end in the grip-operable or grip-safety member G, preferably in the manner described and set forth in my said co-pending application Serial No. 311,689, filed July 17, 1919. The spring 8 surrounds the stem or spindle of the cupped plunger 8 which plunger moves or slides between the grip-operable or grip-safet member G and a guide-face 17, formed in tlTe grip-operable or grip-safety member, the plunger 8 thus engaging the grip-operable or gripsafety member G, the pressure of the spring 8 being upward and the purpose of the spring 8 being to move the firing member or hammer H to fired position, and to afford grip-compression of the grip-operable or grip-safety member, and to return the end of the grip-operable or grip-safety member to engagement with the frame of the pistol after grip-compression. The rod 8 is pivotally attached at its upper end to the firing member or hammer H, and at its lower end is seated in the cupped portion of the plunger 8, the lower end of the rod being rounded or otherwise suitably arranged to afford a ball and socket connection or moveortion of the plunger. The rod 8 is provided with a shoulder 16*, which afi'ords

upper faces

18, and 18, on the sides of the rod.

The resisting and retracting member S is pivotally supported on the rip-stock and comprises two rocker-arms igs. 3 and 5, having forward end-faces S and rearward end-faces S, the forward end-faces S engaging the upper faces 14 of the shoulder 14* of the slidable member or controller N, and the rearward end-faces S engaging the faces 18 and 18' of the rod 8".

The trigger member F is movable forwardly by means not shown, and by pull thereon is movable rearwardly, and is received in the-slot 12 of the slidable member or controller N. as before stated, and has an end 6" for engaging the end face 17 of the sear member S, anda recess 6" for said end face.

In 0 eration: The firing member or hammerbeing in fired position, Fi 1 is moved to firin position, or cocke Figs. 2 andS, by suitable cocking means, or, by contact therewith of a roller R due to rearward movement of the sliding breech action where the pistol is provided with, such breech action, and is locked in firing position by the sear member S, which is actuated or pressed rearwardly by the contactor 13. Grlp-compression of the grip-operable or grip-safety member Gr being released returns the end G' thereof to engagement with the grip-stock, and the slidable member or controller having been moved upward by pressure of the actuator 14", the slidable member or controller N is blocked or locked in upward position by engagement .of the locking-prongs 7 with the en -faces or bottom faces 14 of the slidable member or controller N, which locks the sear member S and firing member or hammer H in firing position, and, when the pistol is provided with a sliding breechaction, also locks such breechaction against rearward movement. The rearward end-faces S of the resisting and retracting member S engaging the

faces

18 and 18 of the rod 8 prevent or resist movement of the firing member or hammer H to fired position because of the engagement of the forward end faces S of the resisting and retracting member with the faces 14 of the slidable member or controller N, the slidable member or controller being blocked against movement as above stated by the grip-operable or grip-safety member G.

The firing member or hammer H being in firing position, Fig. 3, grip-compression of the grip-operable or grip-safety member G releases the slidable member or controller for movement to downward or unlocking position. Pull upon the trigger member F moves the sear member S to release the firing member or hammer H for movement to fired position. The firing member or hammer H when actuated by the spring 8 moves the rod 8 upwardly, which rod carries with it the rearward end S of the resisting and retracting member S, and the forward ends S of the resisting and retracting member S being incontact with the upper surfaces. 14 of the shoulder 14 of the slidable member or controller N, move or draw the slidable member or controller N downwardly against the compression of theactuator 14c and into unlockin position.
