The construction and arrangement of the spring 8e, plunger 8c and rod 8b is preferably the same as the const-rnction and arrangement of these parts described and shown in my said copending application, Serial No. 311,689 filed July 17th, 1919. n

The trigger member F is movable forwardly by means not shown, and by pull thereon is movable rearwardly. The trigger member F is received in an opening or slot 21 in the grip-stock of the pistol, the opening or slot 21 being of such length as to allow considerable play or movement of the trigger member downwardly and upwardly. The trigger member VF is provided with an end-face 22 which is intended to engage or contact with the end-face 14 of the rocking slide-detainer and controller N, and is provided with a mortise recess 23 having a face 24s which is intended to engage or contact with the end-face 17d of the sear member S, the arrangement being such that the end-face 22 will first engage or Contact with the end-face 14 of the slide-detainer and controller N to move the slide-detainer and controller, and that the face 24 will subseqnently engage or contact with the end-face 17d or the sea-r member S to move the sear f member'.

Yoi

The actuator 25, is mounted or suitably arranged on the grip-stock ot the pistol, which actuator comprises a spring 26, and a projector or nose-piece 27, the tendency the spring 2G beingV to torce or push the p ejector or nose-piece against the under edge oi',1 the trigger member F to move the trigger member upwardly in the opening or slot 2l..

The curved arm 28, is pivotally attached at upper end to the tiring member or hammer H, and the lower end of the'arm 28 engages the upper edge of the trigger member l?, the purpose of the arm 28 being to move the trigger-member downwardly in the opening or slot 2l when the firing member or hammer is moved. trom liring position to iired position.

lThe pin 29, or other suitable means, mounted on the grip-stock ot the pistol, provides a guide or the ar1n28 in its movement and also provides a stop means or detent means to limit the upward movement ot the trigger-member when moved by the actuator 25. i

ln operation, the firing member or hammer Il. being iniiring position and the gripoperable or grip-safety member G being in position ot safety, and the rocking slidedetainer and controller N'being blocked in upward locking position, and the scar member S being blocked in position for locking the sear member Vand tiring member or hammer in firing position, Fig. l, grip-compression ot the grip-safety member moves the blocking-member l2 out of position for blocking the rocking slide-.detainer and controller N and the se'ar member El, andpermits movement of the slide-detainer and controller and the sear member, 2. Pull on the triggermember F first engages or brings into Contact the end-face 22 with the end- 'tace Vl-iC of the rocking slide --detainer and controller' N, and rocks or moves the upper end or cranl/.gend tliereo'f downwardly to unlocking` position, Fig.` 3. The same pull on the trigger memberh` subsequently7 engages or brings into contact the Yrace 2li olf the trigger member l* with the end-face 17d. et the swinging sear member S and moves or swings the sear member Ydownwardly out of engagement with the ring member or hammer H, and the tiring member or hammer is moved by `the spring 8E to redposition and the pistol is discharged.

As the iiring 'member or hammer H is moved from firing position to tired position the arm 28 engages or bears down upon the upper edge of the trigger member F and forces the end of the trigger-member downwardly in the opening orslot 2l against the compression ot the actuator 25, and thereby provides clearance or Vspace to permit 'upward swinging movement. of the sear melliber S and upward movement ot' the lower end of the rocking slide-detaiuer and controller N.

As the tiring member or hammer H is moved it'rom tired position to iiring or cocked position and grip-compression of the gripoperable or grip-safety member G is released, and this member returns to position of satety, the pressure of the arm 28 on the trigger member F is relieved and the trigger member is moved upwardly in the slot 2l to its first position by the actuator 25; the rocking slide-detainer and controller N is rocked or moved upwardly by the actuator 20 into position for locking the main-slide C against rearward movement, and the swinging sear member is moved or swung upwardly by the actuator 20 to lock he firing member or hammer H in liring position, while the blocking member 12 through pressure of the actuating springs 13 and 13, as the grip-operable or gripsa'lfety member (l is moved to position ol safety, moved into position ior blocliim` the scar member inV saiil locking position, and 'for blocking the rocking slide-detainer and controller N in its locking position.
