MAGAZINE-PISTO L.

SPECIFICATION forming part 0f Letters Patent N0. 566,513, dated August 25, 1896. Application filed August 15,1895. Serial No. 559,351. (No model.)

.To all whom, it may concern:

Be it known that I, WILLIAM H. GATES, a citizen of the United States, residing at Vorcester, in the county of lVbrcester and State of Massachusetts, have invented a new and useful Improvement in Magazine-Pistols, of which the following is a specification.

My invention relates to a magazine-pistol or similar iirearm, and the object of my invention is to provide a strong, simple, and compact rearm which will shoot more accurately than the ordinary revolver, and in which the operating mechanism is so constructed that there will be little danger of accident.

To these ends my invention consists of the parts and combinations of parts as hereinafter described, and more particularly pointed out in the claims at the end of this specification.

In the accompanying two sheets of drawings, Figures l, 2, 3, and 4 are sectional views of a magazine-pistol constructed according to my invention, the operating parts being shown in different relative positions. Figs. 5, 6, and 7 are sectional plan views, the parts being shown in dierent relative positions; and Fig. 8 is a transverse sectional view, illustrating the action of the ejector.

magazine pistol or firearm constructed according to my invention comprises a sliding bolt which is arranged to feed a cartridge into the firing-chamber, and an operating-piece for the bolt, said bolt and said operating-piece being provided with engaging surfaces for locking the bolt in its forward position, so that it will not be thrown back by the concussion or recoil when a cartridge is exploded.

In the construction as illustrated the sliding .bolt is provided with a spring firing-pin,which is withheld by a sear or detent when the bolt is being moved forward, the scar or detent being released after a cartridge has been fed into the firing-chamber and the sliding bolt has been locked in its forward position. This operating mechanism is located at the rear of the magazine, while the trigger is pivoted in front of the magazine and is connected to this mechanism by a suitable link, which is arranged at one side of the magazine.

It is to be understood that while I have illustrated my improvements as applied to a magazine-pistol certain features of my invention can be employed in rifles or other firearms without departing from the scope of my invention, as hereinafter pointed out in the claims.

Referring to the drawings and in detail, 10 designates a suitable frame; 11, the barrel, having a counterbore or firing-chamber 35 at its rear end; 12, a trigger-guard, and 13 a magazine, which is located near the center of the pistol. The cartridges may be introduced into the magazine 13 in any of the usual ways and will be forced up into position to be acted upon by the operating devices by means of a magazine-spring 14 and a follower 15. The parts thus far referred to may be of any of the ordinary or approved constructions, and need not be described at length.

Mounted in the frame of the pistol at the rear of the magazine, and arranged to force the top cartridge of the magazine into the firing-chamber, is a sliding bolt 16. A cylindrical firing-pin 17, having areduced central portion and collars or enlargements near its ends, is loosely mounted in the sliding bolt 16, and is normally forced forward by a spiral spring 18. A detent or scar 29, pivoted in the framing, extends 'up through a slot in the sliding bolt 16 in position to engage with the rear collar or enlargement of the iiring-pin 17, to withhold the firing-pin until released by the operating piece or lever, as hereinafter described. The sliding bolt 16 is provided near its rear end with a downwardlyextending lug or projection 19, which is slotted, as at 20, so as not to engage or interfere with the scar 29. behind the lug or projection 19 is an operating piece or lever 2l, which is pivoted at its lower end, and iits into a socket in the pistolframe and takes up the concussion, as hereinafter described. The sliding bolt 16 is provided near its rear end with curved surfaces,

Normally engaging which, when the sliding bolt is in its forward position, mesh with and engage

surfaces

22 and 23, which are formed on the lever 2l concentrically with its pivot. 24 is pivoted near its rear end to the sliding bolt 16, and is provided with a slot 25, which fits over and engages a pin in the operatinglever 21.

A retracting-link IOO The trigger 26 is pivoted in the frame of the pistol in front of the magazine, and is provided with the ordinary tri gger-spring 27, for normally holding the trigger in its forward position. A link 28, pivoted to the upper part of the trigger 26 and to the operatinglever 21, forms a permanent connection between said trigger and the operating-lever. By means of this construction, when the trigger 26 is pulled, the operating-lever and the sliding bolt will be moved forward. When the trigger is released, the trigger-spring 27 will move the parts back to their normal position.

As shown most clearly in Figs. to 8, I pro-V vide an extractor-hook 30, which is loosely mounted on the side of the sliding bolt 16 by means of slots, which are engaged by small screws, as 31. The end of the ejector-hook 30 is arranged to fit into a small recess 32 at the side of the firing-chamber. In a firearm as thus constructed the normal position of the parts is illustrated in Fig. 1. When the trigger 26 is pulled, the operating-lever 21 will be turned, forcing forward the sliding bolt 16.

When the sliding bolt 16 has reached the forward limit of its travel, the

surfaces

22 and 23 of the operating-lever will be brought into engagement with the corresponding surfaces upon the sliding bolt, locking the bolt in its forward position some time before the operating-lever is moved into engagement with the sear or detent. Inasmuch as the

surfaces

22 and 23 are concentric with the pivot of the operating-lever, the continued motion of the operating-lever will bring the lever into engagement with the sear or detent, but will not move the sliding bolt. During the travel of the sliding bolt the firing-pin will be withheld by the sear or detent 29. `When the operating-lever is brought into engagement with the sear or detent, the firing-pin will be released and the cartridge will be exploded.

When the pistol is fired,the operating parts will have assumed substantially the position illustrated in Fig. 3, and it is to be noted that the

surfaces

22 and 23 of the operating-lever will be in engagement with the corresponding surfaces upon the sliding bolt, and that the sliding bolt will be locked or held in its forward position, so that the recoil cannot possibly throw the same back, as the sliding bolt and the operating-lever will form substantially a wedging joint, transmitting the entire recoil directly to the frame of the pistol.

When the trigger is released, the parts will be moved back under the tension of the trigger-spring 27, and the slot 25 in the retractin glink 24 will allow the required amount of lost motion to move the

surfaces

22 and 23 out of engagement with the sliding bolt, the parts first assuming the position illustrated in Fig. 4 and then moving freely back under tension of the trigger-spring to their normal position, as in Fig. 1.

As illustrated in Fig. 8, the framing of the pistol is provided with an outlet-chamber 350, having a shoulder 36 near its lower end for normally retaining the cartridges in position.

When the sliding bolt 16 is in its rear position, the extractor-hook 30 will be brought into engagement with a shoulder 37 in the pistol-framing and will be thrown forward so as to be well front of the cartridge-rims. When the sliding bolt 16 is moved forward, the extractor-hook 30 will lit into the recess 32 and will reach the end of its travel before the end of the travel of the sliding bolt.

In practice I have found this loose connection for the extractor-hook an exceedingly desirable feature of construction, as the recess 32 can be made quite small and need not extend a great distance into the firing-chamber, and on this account I am enabled to construct a pistol which lis much more nearly gastight than in constructions in which the extractor-hook is rigidly secured upon the sliding bolt. It is also to be noted that by means of this construction the sliding bolt will start back and will have acquired a considerable amount of momentum before the extractorhook comes into contact with the rim of the shell, and I have found in practice that where this construction is employed the tendency of the cartridges to stick in the ring-chamber will be overcome.

When the sliding bolt is drawn back, the extractor-hook 30 will engage the cartridgerim at one side of the shell, and will turn the front end of the shell out of engagement with the shoulder 36, so that the magazine-spring will force the shell out of the pistol, as illustrated in Fig. 8, bringing the succeeding cartridge in position to be acted upon.

When the pistol is to be put away or not to be used for a time, it is desirable to provide a cover for the ejector-opening, so as to prevent dust from accumulating upon the operating mechanism, and for this purpose I preferably provide a slide or cover, which is opened automatically when the pistol is iired.

Referring to Figs. 5 to 7, 38 designates a slide or cover, which is normally held open by means of a spring 39. At its forward end the cover 38 is provided with a catch or detent 40, which is arranged to engage with a springcatch 41. The spring-catch 41 is offset or provided with a shoulder 42, located in the path of the extractor-hook 30. By means of this construction, when the sliding bolt 16 is moved forward to iire the pistol the extractorhook 30 will throw back the spring-catch 41, as illustrated in Fig. 6, allowing the slide to move back, or open under the tension of the spring 39.

I am aware that many changes may be made in the construction of magazine-firearms by those who areskilled in the art, and that certain parts of my invention can be used in different combinations and in different locations without departing from the scope of my invention as expressed in the claims. I do not IOO IIO

wish, therefore, to be limited to the construction which I have shown and described; but
