MAGAZINE FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 413,734, dated October 29, 1889.

Application filed March 18, 1886;

To all 2071,0122, it may concern: 7

Be it known that I, SYLvEsTER H. ROPER, of Boston, county of Suffolk, and State of Massachusetts, have invented an I'mprove ment in Magazine Fire-Arms, of which the following description, in connection with the accompanying drawings, is a specification,

like letters on the drawings representing like parts.

, one to receive the shell from the barrel, an-

other to aid in inserting the cartridge into the magazine, and another to contain the firingpin, that portion of the carrier which receives the firing-pin also serving as the recoil-block. A cartridge having been inserted within the proper compartment of the carrier from the magazine, the carrier is partially rotated to bring the cart-ridge in it in line with the bore of the barrel, in which position the cartridge is'inserted 'into the barrel, and the carrier is then again partially rotated, so as to bring the firing-pin and recoil-block in line with the bore of the barrel, when the cartridge may, if desired, be exploded, and thereafter the carrier is again partially rotated to bring the shell-receiving compartment in line with the bore of the barrel, and the shell (supposing the cartridge to have been exploded) is extracted or withdrawn from the barrel into the said compartment, and as the carrier is further rotated the said shell is thrown therefrom.

As herein provided for, when the carrier is in position for the firing-pin to explode the cartridge the cartridge-receiving compartment is in line with the magazine.

To, operate the carrier intermittingly, I have provided a cam-rod, the said rod, as herein shown, being rotated intermittingly by means (No model.)

of or through a hand-piece and suitable intermediate devices. The hand-piece, as herein shown, is made instrumental in operating the combined cartridge inserter and extractor, and, as herein provided for, I have made the said inserter and extractor perform a third function-namely, that of setting the 11ammer in position for firing.

My invention in magazine-guns consists, essentially, in an intermittingly-moving carrier having a compartmentfor the reception of a cartridge from the magazine, a compartment for. the reception of the firing-pin and to furnish the recoil-block, and a compartment or space for the reception of the shell from the barrel, combined with a receiver for the carrier, a barrel, and a magazine; also, in a magazine-gun, a carrier to receive a cartridge to be carried into position in line with the bore of the barrel, and a firing-pin, combined with a cam-rod, to actuate the said carrier intermittingly; also, in a magazine-gun, a cam-rod to operate a carrier, combined With a saddle connected with a hand piece and havinga stud to operate the said cam-rod intermittingly.

Other features of my invention will be hereinafter described, and referred to in the claims.

Figure 1 in side elevation represents a magazine-gun embody-ing my invention, the magazine being partially broken out, the carrier being in position for firing; Fig. 2, an enlarged side elevation, the barrel and magazine being partially broken off, the carrier 'beingin position for the shell to be extracted;

The receiver A, of proper shape to contain the carrier, is attached to the stock A, of any usual shape or material.

The receiver A is cut through to receive the carrier 1 which, as herein shown, is rigidly attached to one end of a cam-rod O, the inner end of the rod being shown in Fig. 4 as reduced and as taking a bearing in the wall 2 of the receiver, which wall separates the space in which the carrieris placed from the chamber containing the different parts of the lock, to be described.

The carrier B is so shaped as to present a compartment 1) for the reception of a cartridge from the magazine D and to present a compartment I) (see Fig. 4) for the reception of the firing-pin b the latter being surrounded by a spiral spring N, which, acting at one end against the inner wall of the compartment 1) and at its other end against an annular shoulder of the firing-pin, normally holds the said pin with its rear end beyond the said shoulder out in position to be struck by the projection 3 of the hammer e, pivoted at e, the said projection 3, when operating the firingpin, passing through a hole in the partition 2 and into the open rear end of the compartment in which the firing-pin is located, the rear end of the said firing-pin being supported by an adjustable-bearing 4, shown as screwed into the compartment b. The wall constituting the outer end of the compartment 1) (see Fig. 11) is left of sufficient width or size to constitute the recoil-block If.

The carrier B between the compartments 1) and b is provided with a third compartment or open space I), or is so shaped as to uncover the bore of the barrel F at the time that the shell is to be extracted or withdrawn from the barrel, as will be described, the said compartment or space being shown in Figs. 11 and S as semi-cylindrical, which is the shape preferred. The carrier also has substantially opposite to the compartment Z)" a compartment or space 0, herein shown as partially bounded by a concaved inclined shelf b which is employed when filling the magazine, the cartridge at such time being laid upon the said shelf and pushed therefrom longitudinally by hand into the open rear end of the magazine, the first cartridge having its point pressed against the end of the follower (I acted upon, as usual, by a spring (Z. The receiver has upon it a spring-latch (t the free end of which is normally held in such position (see Fig. 4) as to retain in the magazine the last cartridge inserted therein, this latch being, however, moved to release the cartridge and permit the spring (1' to cause a cartridge to be ejected into the compartment Z; whenever the cam projection cl of the carrier in the movement of the latter meets the said latch.

The carrier B is provided with a carrierlocking device 5, herein shown as a sliding bolt held loosely in position by a screwt' in a slot of the said bolt, the end of the bolt entering a suitable notch or recess in the wall 2 of the receiver whenever it is desired to lock the carrier in place against accidentalmovement,

the locking device being herein shown as so located withrelation to the carrier as to lock it in position for the proper operation of the firing-pin. I have provided the receiver near each end of the carrier with recesses 7 8 (see Figs. 2 and 5) to facilitate the removal of an imperfect cartridge from the compartmentb.

It sometimes happens that a cartridge by reason of imperfection will not readily enter the cartridge-receiving chamber or bore of the barrel, and in such event the cartridge will be picked back by a suitable pin or in strument inserted in the slot 10 (see Figs. 2 and 3) in the wall of the compartment b, the said slot intersecting also the compartment 1), and when the cartridge has been drawn back the carrier will be partially rotated backward by hand until the cartridge comes opposite one or the other of the recesses 7 or 8, and the cartridge may be withdrawn from the compartment through either of the said recesses, whichever may be the most convenient. I have shown the recess 7 as provided with a spring 12, held in place by a screw 13, the free end of the said springbeiug curved or bent outward to normally act as a stop and prevent the accidental slipping of the cartridge backward from the compartment 11 in the movement of the carrier; To accomplish the same object for the recess 8, I have provided a stop 15 on the receiver, using a screw 16 for that purpose, and Fig. 6 shows an imperfect cartridge as being removed.

The carrier and cam-rod are herein shown as connected by means of screws 17.

The cam-rod C, which is one of the peculiar and leading features of my improved magazine-gun, has made in it a cam-groove 0 the shape of which is well represented in Fig. 7, where the said rod is supposed to be split at one side and laid out flat as a plane surface,

and by referring to said figure it will be seen that the said groove from near the inner end of the rod, or nearest the receiver, is made parallel to the axis of the said rod, as at 18, is then curved, as at 1 9, and again made straight,

as at 20; butin the development of the grooves of the rod, as shown in Fig. 7, it will be seen that the straight part 20 referred to is cut longitudinally, or that the part of the said groove marked 20 is shown at each side of the diagram Fig. '7. The straight partQO is joined to the straight part 22 by a curved part 21, g

the straight part 22 connecting with the straight part 18 by a curved pa t 533. groove of the cam-rod is entered by an ad j ustable stud 13, made preferably as a screw, ex tended through a saddle f, which, as herein shown, is shaped to slide upon the magazine I); but it may readily be made to slide upon the barrel F. This saddle has connected with it a bar f, which, extended lengthwise of the barrel F, has its free end entered intoarecess 25 of the receiver A, (see Figs. -t and 11,) the said bar f having pivoted upon it at 26 the combined inserter and extractor, the same The being shown as a finger g, which, at its under side, near itsfree end, has a lug jection g, the said lug pressed toward the center of the barrel F by a suitable spring'g The saddle, as herein shown, has an attached sleeve f ,-to which is or, prooperatively joined the hand-piece H, which,

as herein shown, is made to partially surround the magazine and to be moved longitudinally therefrom. The forward position of the handle and saddle is determined by the bracket or stop h, attached to the barrel bya screw h, the saddle or the end of the sliding barf striking the said bracket. The stop It also serves (see Fig. 4) as a bearing for the outer end of the cam-rod O, the said figure also showing the straight part 20'of the groove, which intersects with the curved parts 19 and 23. The receiver below the recess 25 is slotted, as at 28, for the passage of the projection g of the combined inserter and extractor g, the rear end of the barrel being also suitably notched, as at 29, (see Fig. 4,) to permit the projection g to drop' down and engage the rim of the shell of the cartridge when it is to be withdrawn, the foot 9 during such opera tion traveling through the recess 25. The movement of the bar f into the recess 25 is always far enough to carry the projection g beyond the rear end of the carrier, so that the said projection may be left in proper position when the barf is moved in the opposite direction to engage the rim of the cartridge in the compartment Z) and insert it into the bore of the barrel inposition to be fired by the firing-pin. The hammer e-has a finger-piece e by which to operate-it directly by hand, if desired; but the finger-piece may be omitted; The hammer e at its rear side is provided with a notch 6 which is engaged by the trigger m, pivoted at m and operated by a spring m The hammer is shown as slottedto receive the'stirrup e pivoted at c and connected to the mainspring e. The hammer has at its upper end a projection 6 Fig. 4 in full lines shows the hammer raised; but in dotted lines-the hammer is shown as down. Said Fig. 4 by dotted lines shows the combined inserter and extractor as just engaging the projection e of the hammer, and as the barf is .moved farther to the right in said figure the projection g, acting against the hammer, will raise it into its full-line posi' tion; but while the projection g is so acting. the carrier will be moving into a position dif-v ferent from that shown by full lines insaid Fig. 4. hen the hammer is being set, the barrel will not contain a shellor cartridge.

The usual guard a to protect the trigger has upon it a trigger-lockin g device n, (shown as a screw,) which may be turned in such direction as to act against andform a stop to prevent movement of the trigger in the direction to release the hammer. The hammer is recessed above its pivot e to receive a recoilspring -0, one end of which projecting from being normally kept the said hammer rests against thewall 2 when the hammer is down. I

The outward throw of the mainspring is checked by an adjustable stop 0, (herein shown as a screw,) which is so located as to i stop the said spring just before the projection 3 of the hammer strikes the firing-pin; but the momentum of the hammer is such that it has sufiicient movement after the spring 6 is stopped to impart to the firing-pin sufficient motion to explode the cartridge, the spring 0, the firing-pin having been operated, thereafter acting as a recoil-spring for the hammer.

When the cartridges are to be inserted in the magazine, a catch 25, pivoted at t on the receiver, Figs. 3 and 10, and acted upon by a spring t and having a curved end, enters the groove 18 and serves to hold the shelf b of the carrier in line with the magazine.

Assuming the different parts referred to to be in the position shown in Figs. 1 and 4, with the magazine filled and a cartridge in the bore of the barrel, and the firing-pin invposition to explode the cartridge, the operation will be as follows: The trigger will'be pulled to per mit the hammer to operate the firing-pin and explode the cartridge. This done, the hand} piece will be drawn backward toward the re ceiver, and the stud p, at the commencement of the said movement located at the outer end of the groove 20, will travel along the said groove into the curved part 21, passing the dividing-point 1', (see Fig. 4,) and entering the groove 22, passing along through it into the curved part 23, and therein entering'the straight groove 18, moving therein nearly to the end of the said cam-rod. As the stud passes through the curved part 21, the camrod is partially rotated, and with it thecar rier B, far enough to bring the compartment or space b in line with the bore of the barrel, a'ndas the stud passes along the straight part 22 the cam-rod and carrier remain at rest, while the lug g engages the rim of the cartridge-shell and extracts it from the barrel. After the shell has been fully withdrawn from .the barrel the stud p enters the curved part'23, which again effectsthe partial rotation of the carrier, such movement being sufficientto disengage the rim of the shell from the said projection g, the said movement of the carrier. to release the shell from the proj cation 9 taking place beforethe projection 9 reaches the rear end of the carrier and while the said stud is in the outerpart of the groove 23. The rim of the shell having been carried beyond the projection g, the rotation of the carrier .is continued until the chamber 19, containing the cartridge, is in line withthe bore of the barrel, when the carrier is stopped, the stud p then entering the straight part 18 of the groove 0 and while the hand-piece is moved to complete its inward stroke the projection 9 acts, as before stated, against the projection e to raise the hammer. As the It will be obvious that the extent of move ment of the carrier and its time of movement and rest with relation to the other working parts of the gun may be changed to meet any desired requirement by changing the shape of the groove in the cam-rod. It is also obvious that a cam ledge or ridge on the camrod would be a mechanical equivalent for the groove, and hence would be within the scope of my invention.

I have herein shown the hand-piece as sliding; but in another application, Serial No. 195,667, I have shown the hand-piece as at tached to a lever.
