FIREARM. t

Application filed October 15, 1912. Serial a... 725,950.

- carried out in the specific form of the invem tion herein shown and described with refervence to the firing mechanism, the sear therefor and the sear-tripping or releasing mechanism of an arm of the kind illustrated,

.ior instance, in the patent to Searle, No.

936,369, wherein is employed a device for locking the breech-bolt and the firing mechanism, which device I utilize as a detent in obstructingthe firing movement of the firing mechanism, the releasing movement of the sear and the sear-actuating movement of the sear-tripping mechanism.

In the accompanying drawings, Figure 1 is a view of the improved arm mainly in longitudinal vertical section; Fig. 2 is a rear elevation,-partly in vertical section through the axis of the detent, all parts of the breech mechanism being removed excepting the cocking-lever; Fig. 3 is a view of the improved arm in side elevation, partly broken away and on a larger scale, illustrating mainly the sear locking device; Figs. 4 and 5 are detail views ofsaid sear locking device; Fig. 6 is a side elevation of said detent; and,- Fig. 7 is a sectional view of saiddetent and its means for holding'it at either of its.

limits of movement.-

' The frame a having the grip b; the barrel 0; the breech-bolt d having the removable plug e forming therewith a breech-structure which slides on the frame back and forth under the counter influences of the expl0- sion-pressure and the spring f; the firing mechanism arranged in the plug 6 and including the cocking-lever g and sear g; the

firing-mechanismreleasing means including the trigger it arranged to slide backward and forward in the frame; the locking device or detent consistingofa spindle i journaled in the frame and havin-ga handle 7' and being adapted when turned tojthe dotted line posi- 'tion in Fig. 3 both to leave the breech mech anism free to move longitudinally and the spring a coiled about pin no and having)one cocking-1ever free to move against the firing cocking-lever coincides with a cross cut slotin the spindle 2') and being further adapted, when turned into the full-line position in Fig. 3, to be received by the one or the other of notches (not shown) in the breechbolt to lock the breech-mechanism against longitudinal movement and to oppose firing movement of the cocking-lever (because its slot [is not in registry with lug 7a, which then impinges against the spindle) and the cartridge magazine we entered into the grip from the bottom, are or may be all substantially the same as in the said Searle patent, excepting as hereinafter indicated.

On a pin 11 fixed in the upper back part of the grip is fulcrumed a lever forming the improved 'locking device for the searingtripping and firing-mechanisms. This lever ois suitably shaped from a piece of sheet metal and includes the part-cylindrical or channeled elongated body part 79 having arms projecting from its upper end and formed as follows: From the wall or side of said body part toward the observer in "Fig. 1 project two arms 5 and r; from the other wall or side projects the arm 5. The fulcrum-portion of the lever is located at about the point from where the arms project, suitable holes being provided in its opposite walls'to receive the pin 11.. In the normal or looking position of the lever its bodypart 39 (whose convex' side faces outwardly) is exposed and takes against the upper end of an. opening t formed in the back of the grip, being held in that position by the end bearing against the inside of said ody part and its other end engaged in an opening '1) in the grip. In this position the arm I (which is bent around the magazine) has its free end bearing against a lug '10 project'- ing rearwardly from the trigger, an opening Patented Feb. 3, 19141.

pin (because at that time a lug l1 on 'the a; being formed in the wall 3 of the frame between the trigger and magazine space to admit the arm andbeing or such height as to allow-said arm to rise to the dottedline position in Fig. lto clearthe lug; in the I said position, also, arm s of the lever underlies the heel a at the forward end of the cocking-lever. lvlovement of the lever against the tension at spring a is limited by the stop 1, and when the lever shuts the stop the arms 9 and .9 stand unopposed to the trigger and cocking lever.

The spindle z of'the detent'has a saw-cut or notch 52 disposed in the same vertical plane as that of the plane of movement of the arm 1 The relation of the parts 0 and z is such that in the positions thereof shown in Fig. l (the detent then being in the safe position, locking the cocking-lever and breech structure) the end of arm r abuts the spindle so that the lever 0 cannot be moved to release the trigger and cocking lever, this effect being enhanced by forming the end of the arm concave ito fit the cylindrical surface of the spindle and adapting it to have contact with the spindle somewhat forward of a line connecting the axes of the spindle and lever 0.- In the dotted-line position of the detent (i. 6., the position where it releases the cocking-lever and breech-structure).tlie saw-cut 2 receives the end of arm r, 'so that lever 0 is now free to be moved to ,the position (dotted lines, Fig. 1) where it no longer opposes movement of the trigger and cocking-lever.

The control of the sear is effected from the detent through a lever 3. This lever is in the form of a strip having projecting inwardly therefrom, the lug 4: at one end thereof, the fulcrum pm 5 between its ends and the stud 6 at its other end, said lug having an upstanding toe'7. The pin 5 is fitted lnto a suitable hole in the side of the frame and may be upset at its free end or otherwise. provided with means for retaining the lever fiatwise against the outer face of the frame. Adjacent the forward end of the lever an opening 8 is formed in the frame for the reception of the lug 4, such opening being of suificient.vertical extent to allow the toe 7 on shifting of the lever to move from obstruct-ing'relation to the depending part of. the sear (which is fulcrumed at about the point 9 and is shown in the acting position) downwardly, clear of the same. The rear end of the lever overlies the end of spindle 2', its stud 6 being received by a notch 10 formed eccentrically therein substantially opposite the handle j so that when the detent is turned the lever will be shifted on its fulcrum. The detent is influenced in the usual way by a-' spring-pressed plug 11 (Fig. 7) acting against an angular face 12 of the spindle and'serving to urge the handle of the detent toward and hold it against either of the stops 13-14 on the frame toward which it is moved. The effective width of the notch 10 is sufiiciently greater than the width of the stud 6 and lessthan the extent of movement of the detent determined by said stops so that the first part of the move ment of the detent in either direction is, with respect to the lever 3, los.tmotion; in

the last part of such movement the detent,

urged by the spring-pressed plug 11,.brings by dotted lines in said one side of its notch 10 against the stud, the detent thus shifting the lever on its fulcrum as it moves into contact with one of the stops 1314. WVhen the detent is against the stop 13 (looking the cocking-lever and breechstructure in safe position) it holds the lever 3 in the position where its toe 7 obstructs movement of the sear; when the detent is against stop 14 it holds lever 3 with its toe 7 clear of the sear.

From the foregoing, it will thus be apparent that with the detent in the position shown by full lines in Fig. 3 it holds the levers 3 and 0 in the positions for locking the sear on the one hand and the trigger and cocking-lever on the ment; and that when in the position shown clear of the sear and leaves lever 0 unobstructed. It will be further observed that even with the detent in the latter position a very large measure of safety against unintentional discharge exists in that movement of neither the trigger nor the cocking-lever can take place until lever 0 has been moved out of obstructing relation 'theretoa condition to which, however, the construction and arrangement of the parts readily lend themselves for the quick and effective discharge of the gun by gripping and operating it in the usual way.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination, the gun frame, a mechanism to be controlled arranged therein, an actuating member having limited movement in opposite directions in the frame and also having elastic means to urge it toward each of its limits of movement, and a locking device controlling said mechanism and coupled and movable with said member in each direction, substantially as described.

2. In combination, the gun frame, a mechanism to be locked arranged therein, a fulcrumed actuating member having limited pivotal movement in the frame and also having elastic means to urge it toward and hold it at each of its limits of movement, and a locking lever coupled and movable with said member in each direction and into and out of locking relation to said mechanism, substantiallyas described.
