.- -.iuroma'ric snnr-nonnm rrs'ron To all whom it may concern Be it known that I, HENRY H. TALBOT, a citizen of the United States of America," residing at St. Buchanan and State of Missouri, have invented certain new and useful Improvements in Automatic Self-Loading Pistols, of

Browning April 20, 1897, and the Letters.

Patent granted to myself under Letters Patent Number 882,594, March 24, 1908, the manner of operating my trigger lock being simplified in my present invention over that shown and described in said Letters Patent heretofore granted me; this improvement is provided by a simple escapement. movement by means of which the trigger is automatically locked after each separate discharge and only released when the moving parts have recovered from their re-coil movements and the breech block is again locked in position for another discharge.

I accomplish my object by the mechanism illustrated in the accompanying drawings, in which,

Figure 1 is a longitudinal section of the fire-arm, broken away, shown in firing position; Fig. 2 is a longitudinal section 0 same, also broken away, shown partially open, the trigger lock inoperation; Fig. 3 is a perspective of the trigger; Fig. 4 is a perspective of the trigger lock; Fig. 5 is a detail side view of a rear link provided with a cam, and Fig. 6 is a front view of the same.

Similar letters refer to corresponding parts throughout the several views, as follows:

A is the frame, B the breech-block, C the barrel, 0' a split lug on the barrel which is perforatedat o where a rear link L is pivoted to it, said link being one of a air (the other not shown) upon which the ar- S peclflcation'of Letters Patent.

rel is supported and by which it guided in its movements. 7

1 is the-trigger, a" is a bevel onthe trigger, friction or pressure on which from a correspon bevel h on the trigger lock controls an restrains it, z' is a countersink or slot in the top of the trigger which gives chambe'r'to part of the trigger lock h suspended in the frame above it. I

H s the trigger lock and h is a perforatron for its pivoting in the frame.

71. is an mdention in the lock which is immediately under acam Zt when the arm is in the closed or firing position, as shown in Fig. 1, which permits of a limited vertical movement-of the lock.

I2. is a plane on the shank of the lock on which the cam Z treads while the barrel and breech-block are making their backward and forward movements, as shown in Fig. 2. h is a beveled shank which, when the cam Z is treading on the plane k is depressed and operating on the'bevel i of the trigger I,

forces sa1d trigger I forward and restrains it until said pressure is relieved.

Z'.is a cam on the lower end of rear link L or that art'which is pinioned to the frame, the ength of the link is such that when the barrel moves, it being pivoted to the other end of the link, it carriesthat end through a comparatively large are merely rotating that end upon which is the cam.

From the foregoing description it will be seen that when the various parts are -assembled in their respective positions, their operation is clearly shown as to wit, in the longitudinal section shown in Fig. 1, in

.closed or firing position the breech block B closed andv the barrel C fully forward and v elevated, the upper end of the link L drawn with it by the lug c retiring the cam l to' its rearmost position over the indentation k of the trigger lock H, thus permitting a limited vertical play of the wedge it" so that it exerts no pressure on the bevel 5', permitting a free horizontal movement of the trigger I; in the longitudinal section of Fig. 2

the arm is shown in a partially open or fired position, the breech block B receding from the'barrel C which is depressed drawing the upper en'd of link L rearward and rotating the lower end on its ivot, thrusting forward cam Z into bearlng on plane it, de-

1. The combination in a magazine pistol with a frame, a recoiling -barrel, a trigger and a trigger'lock, of a linkpivoted at the upper end thereof to said recolling barrel, a .cam on the lower end of said link impinging on and co-acting with a plane on the upper surface of said trigger lock to-depress said lock when the barrel recoils.

2. The combination in a magazine pistol with a frame a recoiling barrel and a trigger, of a link pivoted at its upper end 'to the recoiling barrel, a cam on the lower end ofsaid link, a trigger lock immediately above the trigger an pivoted at its front end'in the frame, a rearwardl' extended shank, a plane on the upper sur ace of said lock, a notch in the up er surface of said shank providing a seat or th cam, a rearwardly and downwardly incilined surface bearing at the rear end of the on the trigger, said cam impingin on and co-acting with the plane on sai trigger lock to depress. said lock when. the barrel recoils. 1 q

Intestimony whereof I aflix my signature in presence of two witnesses.
