AUTOMATIC IPISTOL.

To all whom it may concern: Be it known that I, JEAN NICOLAS HENRI.

' JosEPH .GUYo'r, a citizen of the Republic of France, and resident of Paris, France, (postoflice address 23 Rue Moret,) have invented a new and useful Automatic Pistol, which improvements are fully set forth in the fol-- lowing specification.

This invention has reference to automatic pistols of the type which includes a mecha nism'cocked by the recoil of a reciprocating slide and constituting the lock, such mechanism being disclosed, for example, inv British Patent No. 107,317, and consisting, as therein shown, of a pivoted hammer which is operated by a spring-actuated element ar.-

ranged in the handle'and controlled by the trigger. Y

The invention essentially comprehends certain improvements. in or relating to the mechanism aforesaid, itsv construction, -arrangement and mounting, all as hereinafter fully explained.

An embodiment of the invention is illustrated in the accompanying drawing, in which Figure 1 is a vertical sectional view of the improved'pistol, showing the cartridge slip or magazine empty and the slide in its rear or recoil position; and

Fig. 2 is a bottom plan view of the slide. Referring more particularly to the drawing, a indicates generally the handle of the pistol, b the barrel, 0 the magazine or clip, d the spring therein, a the follower controlled by the said spring and 'v the safety catch which coacts with the bottom piece w of'the clip. All of these parts are, or may be, in the main of conventional form excepting in so far as may be stated hereinbelow.

less .of the usual character, and is moved backward in the ordinary manner either by hand or by the recoilincidental to firing, which movement serves to compress the main spring. 9, the latter encircling the guide rod 7' and being interposed between the front wall of a block or body F formed integral with the slide, and the upper rear end or heel of the handle. The chambered lower portion of thebody F receives the usual spring-controlled firing pin k.

The lock mechanism above referred to is carried directly by a trough-like body or 65 sleeve 7:, the lower end portion of which is Specification of. Letters Patent. Patented 1 329, 1920, Application medium: a, .1919. Serial. in. 302,284;

' solid, and the upper portion of the rear wall of which is cutaway or slotted, as at n, leaving an opening or space through which the-hammer i is adapted to swing durmg its cocking and firin movements. This carrier body or sleeve is disposed vertically within the handle a in the space between the rear walls of the latter and the clip c, and is bodily insertible in and removable from such space together with all of its attachments, being held in position therein by means of a removable cross-pin w or analogous device on which the solid lower end of the carrier rests.

The hammer i is pivoted upon the hinge pm I which is mounted transversely in the upperend of the carrier body is, and below said hinge pin the hammer is connected by means 0 a second pin m to the upper end of a block 9, the depending stem n of which is encircled by an expanslble coil-spring R. This spring R tends to force blockg upwardly in the carrier body and, consequently, to swing or rock hammer 2' counterclockwise so as to strike against the firing pin it, assuming, of course, that the various parts are in'position for such action. The slide e, during its recoil movement, engages the hammer and forces it to rock backward and downward into cocked position, in

which the pivot m is disposed substantlally in vertical alinement with the pivot I and with the actuating spring R, the pressure of the spring then maintaining .the hammer cocked. The upward or firing movement of the hammer is effected by means of thetrigger 0, which has connected to it the rod P, the rear end of the latter abutting against a lug t on the block 11 so that when the trigger is pulled, rod will be moved backward and will press lug t and block 9 in the same direction. This movement of said block will shift pivot m slightly to the rear of pivot I, thereby enabling spring R to actuate the hamme Y The clip spring d acts to press the follower a upward in the usual way,-bringing the cartridges successively into position to be forced into the breech chamber 5 during the forward movements of the slide 0. The follower is here shown as .of right-angle shape and as provided at its apex with an upstanding stop lug Z, which latter, when the clip is em ty,w 1ll engage the front wall of the block and thereby lock the slide in its rear position, until the em ty clip is removed and replaced by a ful one, whereupon the slide will be returned by spring 9.

The front sight 1 is of a disa pearmg character, and is formed u on t e front end of a lever 2 which is lcrumed at 3 adjacent its rear end in an open-topped chamber 9 formed in the barrel above the bore. The extreme rear end of lever 2 is normally -pressed u ward by a small spring 4 arranged in sai chamber, so that the front endof the lever carrying the sight is concealed within the chamber. Immediately in advance of the pivot pin 3 there is formed upon the lever a depending lug or finger 6 which projects through an opening 10 in the bottom wall of the chamber into the breech chamber 5. Consequently, the introduction-of a cartridge into the breech chamber will force said finger. ulpward against the action of spring 4 and wil move the si ht into visible position. Hence it is possible to ascertain by merely glancin at the gun to determine if it ,is ready to re.

In order to eject the cartridges, the carrier is provided at its upper .front end with a forwardly-extending toe 7, which is disposed immediately in advance of and in line with a groove 8 (Fi 2) formed in the under face of the b ock l on the slide. When the recoil movement of the slide takes place, this toe or projection will enter and move rearwardly in said groove, and upon the succeeding forward movement of the slide enga and ejects the empty cartridge through t e usual opening (not shown) in the slide.

It willbe apparent from the foregoing that when the clip has been withdrawn from the handle, leavi the lower end thereof open, the carrier can be removed bodily from the handle, together with the block 4 and connected parts and the hammer i, for inspect on, cleaning, re air or other purposes, and that if esire a completel new carrier and its adjuncts of somewhat iiferent character can be substituted for the one pivot, whereb when the two ivots are disposed in vertical alinement wlth each other and with the actuating spring the hammer will be held in cocked position b the pressure of said spring; a lug on sai operating member; and a connectin rod pivoted at one end to the trigger an adapted to bear against said lug at its other end, so as to push the operatmfi member rearward when the trigger is pu ed and thereby disaline the two pivots, to permit said actuating spring to operate the hammer.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
