Specification of Letters Patent.
Patented Dec. 4, 1906.
Application filed April 20, 1905. Serial No. 256,528-
To all whom it may concern.-
Be it known that I, OSCAR F. MossBERG, a citizen of the United States of America, residing at Chicopee Falls, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Pistols, of which the following is a specification.
This invention relates to firearms, and especially to the construction of a multiplebarrel pistol, the object of the invention being to provide a pistol which by reason of its shape may be carried in the pocket without inconvenience and which may be cooked and fired by the actuation of a sliding member which moves in and out of the frame of the arm, all of the operative parts of the device being inclosed, whereby in case of necessity the arm may be fired while held in the pocket, there being no parts extending beyond the frame to interfere with this operation.
The invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the pistol with one cheek-piece removed. Fig. 2 is a vertical section taken longitudinally of the pistol, certain of the parts being left in full lines, the plane of the section being substantially on line 2 2, Fig. 4. Fig. 3 is a sectional view taken substantially in the same plane as Fig. 2, the barrel, however, being shown in elevation and the parts being in the position they would occupy at the moment of firing or just prior to that moment. Fig. 4 is a sectional plan view, the plane of the section being on line 4 4 of Fig. 2. Fig. 5 is an elevation of the rear end of the barrels and the barrel-locking device thereon. Fig. 6 is a side elevation of the barrels and a part of the frame, the barrels being shown tipped down in a position to permit the extraction of the empty shells. Fig. 7 is a transverse section through the barrels on line 7 7, Fig. 6. Fig. 8 is a side elevation of a part of the frame and barrels, the cheek-piece being removed from the frame and the hammer being shown in section in the plane of line 2 2, Fig. 4. Fig. 9 is a perspective view of a rotatable firingpin carried on the hammer. The scale of these drawings is about twice the natural size.
The frame of the firearm is indicated by a and is provided with downwardly-extending portions 1), which constitute bearings for a portionc uniting the two parallel verticallydisposed sides (1 and e. (Shown in Fig. 4.)
The hammer f is pivotally supported on the pin 9 in the upper part of the frame and swings between the two sides (1 and e of the cocking-slide, as shown in the various figures. For convenience of manufacture the pin 9 is supported in a block 9, fixed to the upper part of the frame by a screw 0/, and it will be referred to farther on.
Near the bottom of the cocking-slide the cocking-lever h is pivotally supported on the pin j, the upper end of this lever engaging a notch k in the hammer. On the pin 9' is a spring m, bearing on the bottom of the slide and the bottom of the cocking-lever h to hold the upper end of the latter in operative relation to the notch 7c. The mainspring, is indicated by 0, and it consists of a U-shaped spring supported in the frame between the cheek-pieces p and bearing by one end on the hammer, a roll 1" being mounted on the latter to do away with the friction between the hammer and the end of the spring. A spring 8, suitably located in the frame, is connected with the cocking-slide, as shown, whereby after the slide has been moved into the frame it may be returned to normal position, the two extremes of the movement of this slide being shown in Figs. 2 and 3.
It is immaterial what form of spring is used for the slide or how it is applied thereto, as any spring having suflicient force and scope to return the slide from the position shown in Fig. 3 to that shown in Fig. 2 may be employed.
The barrels t are pivotally hung to the frame on the screw or pin 1), and suitably located on that side opposite to this pivotal point is a locking-lever w, which is pivoted in a slot milled in the extension 00 of the barrel on a pin y and is provided with a hooked end 3, which snaps over the edge of the frame a to hold the barrels up against the front end of the frame in firing position, a suitable spring 4 serving to hold this hooked end in engagement with the frame, the latter being cut away, as shown at 5, Fig. 6, to receive the end of the locking-lever.
The barrels t, as shown in Fig. 7, are four in number and made in one piece, being grouped equidistantly about a common center, and at this central point a hole is bored to receive the extractor-stem 6, which is pro vided with a spiral spring 7, one end of the stem being connected to a U-shaped yoke 8, (shown in Figs. 4 and 5 most clearly,) which constitutes with said stem means to extract the empty shells from the four barrels simultaneously, the yoke 8, as shown in Fig. 5, being notched at the proper places thereon where it extends across the open ends of the barrels to engage the shells 9 under the heads thereof as shown in Fig. 6.
The opposite sides of the barrel are pro vided with grooves in which the yoke 8 may slide, there being a stop pin or screw 10 in each leg of the yoke to'limit the movement thereof outwardly, the ends of these stoppins entering grooves 12, milled into the sides of the barrels and bringing up against the end of the slot when the extractor is moved outwardly, as in Fig. 6.
As usual with extractor devices, that part which engages the shells is let in flush with the end of the barrels.
This pistol being one of that type in which the barrels are stationary, the hammer is provided with a rotating firing-pin 14, having a projection 15 thereon which will strike the cartridge in a manner to ignite the charge therein when the hammer falls. This firing pin or head is provided with ratchet-teeth on the back side thereof, as shown in the various figures of the drawings and indicated by 16 and is shown in perspective in Fig. 9. This is mounted rotatably on the pin 17 on the front side of the hammer at the lower end thereof and when the hammer falls reaches the cartridges through an opening 14 in the front end of the frame. This firing pin or head is so positioned as to be engaged by the hand 18, pivotally supported at 19 in the block g.
As shown in the plan view in Fig. 4, the location of the hand is near one side of the hammer, which has a slot 20 (shown in Fig. 8) milled therein, in which the hand may play and whereby the lower end thereof in engagement with the ratchet-teeth 16 of the rotating firing-pin may be steadied, the hand be ing held in operative relation to the ratchetteeth by means of a spring 21, fixed by one end on a. pin 22, and whose opposite end passes through the hub of the hand, as shown in Fig. 8. Therefore the hand swinging on its pivot will follow the movements of the hammer, the extremes of the movement of the hand being shown in Figs. 1 and 8, and it will be observed thatas the hammer moves fromthe position shown in Fig. 1 backward and upward it is moving toward the axis of the hand. Therefore the engagement of the latter with the ratchet-teeth of the firinghead will effect the rotation of the latter, and,
vice versa, as the hammer swings forward the lower end of the hand will swing upward to engage another tooth of the ratchet, the distance between the pivotal points of the hand and the hammer being such as to provide for the required degree of rotation of the firing pin or head.
If more or less than four barrels were to be used, then the distance between the axis of the hand and the hammer would have to be varied in a manner to give the desired throw to the firing-pin.
The cheek-pieces 29 may be secured to the frame by means of a screw 23 or in any convenient way.
Reference has been made to the block g, which is located in the upper forward end of the frame, being secured therein by the screw 0/. This block is employed merely as a convenience in manufacture, and a plan view thereof would show that it consists of two parallel plates united together by that portion thereof into which the screw a enters. One of these plates 24 (shown in Fig. 3) is shorter than the'other, which is indicated by 25 and seen in Fig. 8. 24 and 25 the hammer is hung, as stated, on the pin g, .and on that part of the plate 25 which extends beyond the plate 24 the hand is supported, as shown in. Figs. 1 and 8, the hub thereof extending through the plate.
In using this pistol the arm is held in the hand in such osition that the upper edge of the frame will rest against the palm of the hand, the second finger passing under the cocking-slide and the barrels extending out from between the thumb and the forefinger.
The main portion of the arm is thus inclosed in the hand, and by the contraction of the second finger the cocking-slide is moved from the position shown in Fig. 1 to that shown in Fig. 3, swinging back the hammer, which at the limit of its movement becomes disengaged from the cocking-lever h and is thrown by its spring 0 forward against a cartridge, and as the hammer'is drawn back to cocked position the firing-pin 4 will be partially rotated by the action of the hand, as explained, and brought into position to strike another cartridge when it next falls. WVhen all of the barrels have been discharged, the hooked end 3 of the locking-lever w may be thrown out of engagement with the frame and the barrel swung down to the position shown in Fig. 6, whereupon the extractor-yoke 8 may be actuated to remove the empty shells from the barrels preparatory to reloading the latter.
It is desirable to prevent the firing-pin 14 from being rotated past the point at which it is desired to stop it, which might happen should it by reason of long use wear loose on the pin 17, on which it'is supported, and therefore a springactuated stop-pin 26 is located in the hammer, as shown in Fig. 2, with its Between these plates point extending out from the edge thereof, which by the spring 27 is held in yielding contact with the rear end of the firing-pin in such position that it will be located in front of one of the ratchet-teeth 16 by the movement of the hammer when the firing-pin has reached the limit of its rotative movement through the action of the hand. By means of this spring-pin the firing-pin will therefore rotate under a suflicient frictional resistance to prevent it from overthrowing. The position of this pin relative to the rotatable firing-pin is shown in Fig. 9.
Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is
1. The combination in a firearm-of a plu rality of stationary barrels, a cocking-slide movable reciprocally in the frame of the arm, a hammer operatively located relative to the cocking-slide, and mechanism actuated by the movement of the slide to swing the hammer to full-cocked position a rotatable firingpin on the hammer, and means, permitted by the movement of the hammer to rotate the firingpin to'locate the same in operative relation to each barrel in succession, said means comprising a spring-actuated swinging hand located in the hammer.
2. The combination in a firearm of a plurality of stationary barrels, a cocking-slide movable reciprocally in the frame of the arm, a hammer operatively located relative to the cocking-slide, and a cocking-lever on the slide to engage the hammer; a rotating firingpin on the hammer having ratchet-teeth thereon, and a hand arranged to engage one of the ratche t teeth during movement of the hammer to locate the rota able firing-pin in proper relation to the barrels.
