WILLIAM TRABUE, OF LOUISVILLE, KENTUCKY.

To all 'whom it may concern:

Be it known that I, WILLIAM TRAPUE, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, haveinvented certain enable others skilled in the art to which itappertains'to make and use the same.

In all magazine iii-e arms with which I am familiar, it becomes necessary before the weapon is in condition for automatic action,

vto operate' certain exposed parts of the gun by dexterous manipulation, requiring both hands, this involves the expenditure of time, which under some circumstances proves disastrous. f

The construction and operation of my improved weapon is such that in the act of the stock .the breechv block 1s retracted and cocked, and the safety .device for holding the cartridges against accidental movement is automatically operated, so that the first shot may be instantly fired.

My invention therefore has for its object to produce a fire arm of the automatic magazine type by which the first shot may be fired without the necessity of manually cocking the fire arm or releasing the safety device, and which may be operated entirely with one hand.

My invention also has for its object to provide means for holding the -cartridges within the magazine, said holding means automatically releasing the cartridges when the weapon is put into action... n

lYVith theseA objects in view my invention consists of the means hereinafter described by which the breech block is retracted and the cartridges within the magazine are permitted to be successively forced into aline'- ment with the bore of the arm, and the safety device over the upper end of magazine automatically released.

My invention also consists in the details of construction and arrangement of the several parts as will be hereinafter more fully explained.

In order that those skilled in the art to which my invention appertains may know how to make and use my improved fire arm I will proceed to describe the construction and operation of the same, referring by the Specification of Letters Patent.

numerals to the accompanying drawings, in n which,

Figure l is a side elevation with the breech block in its forward position, over the magazine. Fig. 2 is a similar view with the breech block in its retracted position, showing acartridge released from the magazine and in position to be forced into the bore of the gun and exploded by the forward movement of the breech block when it is released by a pull upon the trigger. -Fig. 3 is a centra-l longitudinal, vertical sectionon enlarged scale, the. cartridges being shown iu elevation. F iggf isa transverse vertical section on the line 1a-4a of Fig. 3. Fig. 5 is a. perspective view of the cooking lever and its spring actuated pawl removed from the the firing takes place and is continued.

Similar reference numerals indicate like parts in the several figures of the drawings.

l represents the stock, and 2 the barrel of a pocket pistol. The front of the stock below the trigger guard 3 is preferably formed with a curved depression 4:, for the middle finger of the user. The rear end of the stock is formed with a recess within which is pivoted at 5 a vibrative member 6, which member is formed with a recess 7 for the reception of a spring 8, one end of which is connected with a bell crank lever`9 to be presently described, and with a second recess 10 within which is pivoted at 11 a triangular shaped dog 12 operated by a spring 13, one end of which is connected with the dog and the-other bearing against the wall of thel recess 10. The breech of the gun is formed with the usual racc for the reciprocating breech block la, provided with a suitable extractor l5 and ejector 16. lVithin a suitable recess in the stock is located the magazine 17 formed at its upper end with a curved stop 17X, and a follower 18, actuated by a spring 19, said magazine is removably locked in position by a suitable latch 20. The bell-crank lever 9 hereinbefore referred stock and its upper slotted end is connected with the breech block 14 by a pin shown in broken lines in Fig. 3. The lower free end of this lever is formed with a lateral lug or projection 22, with which the lower extremity of the triangular dog 12 contact's during the forward vibration of the member 6 to operate the lever 9, and from which it is released on the completion of said movement, and is returned to its normal position by the spring 13, the lug or projection 22 traversing the face of the dog in an obvious manner.

The scar 23 shown in dotted lines in Fig.

3 is pivoted at 24 between the 'stock l and one of theiface plates 25, and is provided at its rear end with alateral projection or lug 23X adapted to intersect the path of the breech block and hold the same in cocked position, until the sear is vibrated upon its pivot 24. When a pull is made upon the trigger 26, to which is pivoted at 27 a vibrative dog 28 formed at its upper free end with a shoulder, to Contact with a lateral lug or pin 29 on the forward end of the sear 23, said Sear is operated to release the breechblock, said dog is also provided above its shoulder with an incline surface adapted to contact with a pin 30 which acts as a guide for the same. A spring 31 retains the dog 28 in its operative position, a spring 32 restores the sear to normal position, and a spring 32 returns the trigger to its initial position. The safety device for holding the cartridges against the action of the spring 19 in the magazine until they are automatically released, consists of a horn-shaped arm 33 pivoted at 34, and provided with a sprin 35, as best seen in Fig. 6.

Referring to Fig. 7 an arm 36 is pivoted at 37 to the member 6, and is provided at its upper end with a finger 38, sc located that when member 6 is depressed, the finger 38 will enter a' slot 39 in one side of the stock and rest between the upper surface of the member 6 and the under wall of a recess in the rear of the stock, said linger being automatically thrown into the position shown in Figs. 2, 3 and 7 by a sprin 40 when the member 6 has reached the limit ofA tracted, safety arm 33' is depressed, the

breech block is then allowed tov resume its forward position, at which time the loaded magazine 17 may be placed in position and secured by latch 20, the pistol is then ready for use. When it is desired to discharge the pistol quickly and successively the stock is grasped with the second finger of the hand in the depression 4, with the base 0f the thumb in contact with the rear surface of the vibrative'member 6, and. by pressure on the member 6 it will be caused to swing forward on its pivot 5 causing the dog 12 to contact with the lateral lug 22 on the lower end of the bell-crank lever, 9, thereby swinging the latter upon its pivot 21, and by reason of the connection between the upper end of thelever 9 with the breechblock 14, the latter is retracted until the lu 23c on the end of the sear 23 is brought in ont of the forward end of the breechblock and the same is thus held in cocked position. During movement of the member 6 the space between its upper surface and the lower wall of the. recess in the rear of the stock has become sufficient to permit the finger 38 on the arm 36 to assume the position shown in Fig. 3 and thus locks the member 6 against return movement. As the breechblock is moved rearwardly the horn-shaped detent or safety device 33 under the influence of its spring 35, is vibrating upon its pivot 34 and permits the uppermost cartridge in the magazine to be forced by the spring follower in the magazine into the position shown in Fig. 3.

By reference to Fig. 6, it will be seenl that the horn-shaped safety device 33, vis rendered voperative as above described `by reason of the spring'35, the forward extremity being pivoted on the stock and extending rearwardly having connected therewith, in rear of its axis, the spring 35; when the rear end of the safety device is manually forced downward, the spring 3 5 is put under strain, and the in this position while the breechblock is in its forward position. A pull now upon the triggerQt' causes the shoulder in the upper end of the dog 28 to press against the lug or pin 29 in the forward end of the sear 23 which vibrates the latter upon its pivot 24,.

and causes the lug 23x to retreat below the path of the breechblock and the force exerted by the spring 8 connected with the bellcrank lever 9 forces the upper end of the latter forward, carrying with it the breechblock 14 which forces the cartridge into position in the bore of the gun and discharges the shell in an obvious manner.

The recoil produced by the explosion of the charge, forces the breechblock backward and the extractor 15 carries the empty shell with it'until the ejector 16 is forced forward bv the contact of its rear end with the breech of the gun, which ejects the shell in a 1iteral direction through the side of the parts areheld breech. Coincidentally with this action the' sear spring causes the sear 23 to assume the position shown in Fig. 3, andfto hold the breechblock in cocked position, whereupon` the next shot may be fired by a pull in the manner herein described upon the trigger,

' and this action may be repeated until all the cartridges in the magazine have been exhausted. Shouldit be desired to. stop firing at any time, the horn-shaped safety device is forced downwardly which in turn forces the cartridge which had previously been brought into alinement with the bore back into the magazine, and by again o erating the trigger 26 the breechbloc is caused to assume a forward position over the upper end of the magazine. As the breechblocl: is retracted the safety device escapes from beneath same, and the upper cartridge in the magazine is forced up into line with the barrel by the spring 19.

From the description of the construction and operation of my improved gun it will he appreciated that the first shot may be tired instantly and without any previous manipulation of anyA individual part.

Changes in detail of construction may be made without departing from the spirit of my invention, which rests in cooking the arm, releasing the safety device above the magazine and placing the cartridge in position to be forced into the breech and exploded by exerting pressure upon the front of the stock and upon the member 6.
