FIREARM.

Specification of Letters Patent.

Patented April 17, '1906.

Application filed October 2, 1905. Serial No. 281.006-

lo all whom it may concern.-

Be it known that I, JULEs L; SAGET, a citizen of the United States, residing at New Orleans, in the-parish of Orleans and State of Louisiana, have invented new and useful Improvements in Firearms, of which the following is a specification.

. My invention pertains to firearms, more particularly shoulder-firearms and it has for one ofits objects to .provide a firearm constructed with a View of. using a subcaliberbarrel or barrels and provided with means for conveniently carrying the subcaliber barrel or barrels when the same are not in use.

Another object of the invention is the pro- Vision of afirearm embodyinga rectilinearlymovable breech-bolt and simple, strong, and reliable means whereby thebreech-bolt may be quickly.and easily locked in its closed position and as readily unlocked when desired.

Other advantageous, features. peculiar to my novel firearm will be fully understood from. the following description when the same is considered in connection with the accompanying drawings, forming part of this specification, in which-T I Figure 1 is a side elevation of the firearm constituting the present and preferred embodiment of'my invention. Fig. 2 is a top plan viewof the same. Fig. 3 is a longitudinal vertical section of the. firearm. Fig. 4 is an enlarged transverse section taken in the plane indicated by the line 4 4 of Fig. 3 looking in the direction indicated by arrow. Fig.1 5is a perspective view illustrating the breech-bolt and the parts carried thereby removed. Fig. 6 is a detail perspective view illustrative of'the breech-frame of the firearm.

.Figs. 7 and 8 are enlarged. detail longitudinal vvertical sections of the firearm. Figs. 9 and .10 are rear end elevations of the subcaliber barrels. Fig. 11.is a side elevation of the extractor which is'employed on the breech-bolt when the smaller of the two subcaliber barrels is in use. .Fig. 12 is a similar view of the extractor used in combination with the larger of the subcaliber barrels, and Fig. 13 is a side elevation of the plug for closing the cylindrical. casing in which the subcaliber barrels are contained when said barrels are not in use.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which A is the stock, and B the barrel, of a shotgun, which may be and preferably is of the standard size and weight. In the rear or shoulder end of the stock a pocket a is preferably provided, said pocket being normally closed by a spring-pressed door b, hinged to the butt-plate c and being designed to hold extractors when the same are not in use, as illustrated in Fig. 3. I

Fixed with respect to the stock A and barrel B in the ordinary manner or any other manner compatible with my invention is a breech-frame O. (Best shownin Fig.6.) This breech-frame O is generally tubular in form and is provided in the upper side of its forward portion with an opening (1 for the insertion of cartridges and the removal of shells, and in the upper side of its rear portion with a longitudinal slot 6, which extends from the opening (2 to the rear end of the breech-frame for a purpose presently set forth. Said breechframe is also provided with an opening f,

formed in its bottom adjacent to its rear end, and, further, with a plain lug g and a hookshaped lug it. These lugs g and h are formed integral with or otherwise fixed to the breechframe C, and the lug g is arranged on the upper portion of the frame at one side of the slot 6 and adjacent to the rear end of the frame, while the lug It extends from the side of the frame beyond the rear end thereof and is arranged at the opposite side of the slot 6 with reference to the lug g.

D is the breech-bolt, which is movable rectilinearly in the breech-frame O to open and close the rear end of the barrel B, and E is a transversely-swinging locking'member. This locking member E comprises a collar i, which loosely receives and is adapted to' turn within certain limits on the rear end of the bolt D, an arm j reaching radially from said collar and having a reduced portion 7a and an arm I reaching laterally and forwardly from the collar at an opposite point with reference to arm and having a kerf m in its inner side. The collar 2' is held against movement on the bolt D in the direction of the length of the bolt by any suitable means such, for instance, as the pin n, fixed to the bolt and resting in a slot p of the collar. The bolt D, while free to move endwise forwardly and rearwardly in the frame C, is normally held against withdrawal from said frameby a screw F, which bears in the side of the frame and has its inner end disposed in a longitudinal groove 2" in the bolt, Fig. 4.

It will be apparent from the foregoing that when the bolt D is moved forwardly in the frame C until the collar 7'. brings up against the rear end of said frame and the locking member E is swung toward the right the reduced portion is of said member will seat in the hook-shaped lug h of the frame,while the kerf m in the arm Z of the member will receive the lug g of the frame. In consequence of this the breech-bolt will be strongly held in its forward position in the breech-frame in such manner that there is no liability of its being casuallyreleased. When, however, the gunner desires to open the breech, he has but to grasp the arm of member E and swing the said arm upwardly, when the member E will be disengaged from the breechframe and may be used as a means to move the breech-bolt rearwardly and forwardly.

,1; G is a sear suitably mounted in the stock A and connected with a trigger H, and I is a firing-pin mounted in guides in the bolt D. The said firing-pin is surrounded by a spring .9, which is interposed between its enlargement t and one of the guides in the bolt D and tends to press the pin forwardly. It is also provided at an intermediate point of its length with a beveled lug u and at its rear end with an enlargement Q). When the breech-bolt is moved rearwardly, the firing-pin will move with it, the beveled lug a riding over the sear G. On the subsequent forward movement of the breech-bolt, however, the lug u will bring up against the sear G, with the result that when the breech-bolt is locked to the breech-frame the firing-pin will be cooked.

J is an extractor detachably connected, preferably by a screw w, to the upper side of the breech-bolt D. This extractor extends in advance of the forward end of the bolt D and is provided with a beveled head ac, designed to rest in a notch y in the forward end of the breech-frame C and engage the rim of a cartridge, so that when the breech-bolt is I moved rearwardly the cartridge will be drawn out of the barrel B and into the breechframe, from whence it may be readily re moved.

K is a spring-bar arranged alongside of and connected at its rear end to the breech-frame C and having a lateral projection .2 at its forward end disposed in an aperture a of said frame, and L is a screw-bearing in the bar K and against the outer side of the frame C. T/Vhen the screw L is turned inwardly, the forward end of the bar K and the projection .2 will be drawn outwardly, and hence a subcaliber barrel may be shoved forwardly into the barrel B and past the projection 2. When, however, the bar K and the projections 2 rest in their normal positions, the latter will obviously hold the subcaliber barrel against casual rearward movement in the barrel B.

- Fixed with respect to the stock A and the barrel B and arranged longitudinally below the latter is a cylindrical casing M open at its forward end. Thiscasing is normally closed by a plug lV having a knurled edge, and when desired the said plug may be equipped with a screw-driver b, which may be used to loosen and tighten the screw w for connecting the extractor J.

N is a comparatively large subcaliber bar rel. P is a small subcaliber barrel, and Q is a collar designed to be mounted on the forward end of the subcaliber barrel P when the latter is placed in the barrel B, with a view of holding said forward end against lateral deflection. These parts are designed when not in use to be arranged in the casing M, as shown in Fig. 3that is to say, with the bar rel P in the barrel N and the collar Q between the ends of said barrels N and P and the plug M. The subcaliber barrels N and P are respectively provided at their rear ends with a rim 0, having a notch d to receive the head of an extractor and a recess 6 to receive the projection 2 on the bar K.

R and S are extractors designed to be used in combination with the subcaliber barrels N and P, respectively. These extractors are similar in construction, except that the head of the extractor S is longer than that of the extractor B. When not in use, the said extractors are designed to be carried in the pocket of the stock, as shown in Fig. 3.

When it is desired to use one of the subcaliber barrels in my improved firearm, the screw F is loosened, the breech-bolt D is removed from the breech-frame C, and the screw L is turned inwardly to move the projection 2 on bar K outwardly. With this done the desired subcaliber barrel is moved from the casing M and removed forwardly through the breech-frame C and the barrel B until its rim abuts against the rear end of the barrel B, when the screw 'L is turned outwardly to move the bar K and the projection 2 inwardly, so as to seat the latter in the recess in the rim of the subcaliber barrel, and thereby secure said barrel against casual movement relative to the barrel A. The breech-bolt D is thenreplaced and secured in the breech-frame C, and the extractor B or S, corresponding to the subcaliber barrel put in use, is substituted for the extractor J.

When the firearm is changed, as described in the foregoing, it will be apparent that it cofpstitutes either a small-bore shotgun or a r1 e.

To restore the firearm to its original condition shown in Figs. 1 to 3, it is simply necessary to remove the subcaliber barrel from the barrel B and place said subcaliber barrel in the casing M.

It will be gathered from the foregoing that the owner of my novel firearm is enabled while in the field and without the employment of skilled labor to readily convert the firearm from an ordinary shotgun into a small-bore shotgun or rifle, or vice versa, also IIC that the firearm embodies no delicate parts, and is therefore well adapted to withstand the usage to which firearms are ordinarily subjected.

By reference to Figs. 7 and 9 of the drawings it will be observed that the smaller subcaliber barrel P is arranged 05 the center of its rear enlargement a and the collar Q. By virtue of this when the subcaliber barrel is placed in the barrel B and a small rim-fire cartridge is placed in the subcaliber barrel the firing-pin I when impelled forward will strike the rim of the cartridge and explode the same.

When the barrel B is employed alone orthe larger subcaliber barrel N is placed in said barrel B, it will be observed that the firing pin I will strike the center of the cartridge placed in said barrel B or N. From this it follows that Without change in the firing mechanism my novel firearm is adapted to explode either center-fire or rim-fire cartridges.

M is a shell-ejector. This ejector comprises a plunger m movable upwardly and downwardly in the stock and extending into the lower portion of the breech-frame, and a spring m carrying the plunger and connected at its end remote from the same to the under side of the stock, as best shown in Fig. 7. The upper end of the plunger m is beveled at the rear, as shown, and hence it will be seen that when the breech-bolt is moved forwardly it will ride over and depress the plunger, and thereby place the spring m undertension. When, on the other hand, the breech-bolt is moved rearwardly and the extractor J brings a cartridge-shell with it, the rim of the shell will assume a position above the shoulder of the plunger, so that when the plunger is released by the breech-bolt and impelled upwardly by the spring m it will operate to forcibly throw the shell out of the breechframe through the opening in the top thereof.
