SPECIFIGATIONforming part of Letters Patent No. 521,624, dated June 19, 1894. Application filed August 29, 1892. Serial No. 444,440. (No model.)

To all whom it may concern.-

Be it known that I, PETER SHEOKLER, of Stockton, in the county of Rooks and State of Kansas, have invented certain new and useful Improvements in Firearms; and I do hereby declare that the following is a full, clear, and

' exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and numerals of reference marked thereon, which form part of this specification.

This invention relates to certain improvements in fire arms, and the invention consists in certain novel features of construction and in combinations of parts more fully described hereinafter and particularly pointed out in the claims.

The object of the invention is to provide an improved magazine gun simple, durable and economical in construction and very effective in action, convenient to handle, and wherein the magazine can be easily and quickly removed when desired and another substituted, and wherein the magazine is not liable to clog or choke.

A further object of the invention is to provide an improved bolt magazine gun having a removable belt magazine and improved feeding mechanism therefor controlled by the movement of the bolt operating lever.

A further object of the invention is to provide an improved lock mechanism exceedingly simple and yet very durable and effective in construction.

A further object of the invention is to provide certain details in construction, arrangements, and combinations of parts whereby a highly efficient and durable gun is provided.

Referring to the accompanying drawings,- Figure 1, is a side view of the repeating fire arm. Fig. 2, is a detail elevation of the bolt and actuating lever and theloclgdotted lines showing the parts in different positions. Fig. 3, is an elevation showing the receiver and adjacent parts, the operating lever shown thrown down with the cartridge partially inserted in the firing chamber, the magazine belt not being shown.

Fig. 7, isa detail perspective view showing one end of the magazine belt feeder and the inner end of the lever for operating the same. Fig. 8, is a detail perspective of one side of an end of the lock frame, and one side of one end of the actuating lever, and the spring carried by said frame and arranged to engage the front end of said lever. Fig. 9, is a top plan view of the construction shown in Fig. 5. Figs. 10 and 12 are detail top plan views of the magazine belt feed mechanism showing the same in different positions, respectively. Fig. 11, is a cross sectional view on the line yy Fig. 10.

In the drawings the reference letter a, indicates the barrel of the fire arm.

01', indicates the stock of the arm of any suitable or ordinary shape and construction.

e, indicates the receiver shell or case suitably constructed and in which the stock is secured. The rear or chamber end of the barrel is suitably secured in the receiver as by a screw threaded connection.

At the rear openend of the firing chamber of the barrel the receiver is provided with a longitudinal chamber f, open on each side and of greater length than the cartridge for which the arm is adapted. In the receiver below said chamber the magazine or repeater feed mechanism is located. A shell or case g, is fitted over said feed mechanism and extends down over the sides of the receiver and is suitably secured by screws or the like. This shell is rounded at the edges so as to form the bottom of the chamber f semi-cylindrical or transversely convexed, as shown, and is provided with a central longitudinal dovetailed or undercut guideway h, in its top extending throughout its entire length from the firing chamber to the receiver in rear of chamberf.

z', indicates the breech bolt arranged to slide longitudinally of said chamber f, and force the cartridge into the firing chamber. This breech bolt is provided with a longitudinal guide rib j on its under side which fits and slides in the guide way It in the bottomof chamber f, having the lateral lugs 70, at its front end sliding under the undercut edges of the guide way so that the rear end of the tenses bolt can have a limited vertical rocking movemen t. It is understood that the bolt contains the firing pin Z, extending loosely and longitudinally therethrough, and that the bolt forces the cartridge into the firing chamber and after the discharge extracts the cartridge and if the arm is being employed without the repeating or magazine attachment the car tridge after being extracted drops laterally from the bolt and out of chamber f. To accomplish this function the front end of the bolt is provided with the extractor hook 071., projecting forwardly from the front end of guide rib j, with its hook shoulder on its upper edge, the end of the hook being beveled up and down. This extractor hook is free to swing vertically and has preferably no spring. The rear "end of the barrel beneath the end of the firing chamber is slotted at n, to receive said hook and permit it to slide beneath the end of the cartridge and catch on the rim of the cartridge. A spring actuated pin 0, having a beveled head is located in the bottom of slot n, so as to operate vertically and crowd the extractor hook up against the cartridge when the bolt is forced home. This spring pin insures the extractor hook tightly engaging the cartridge until it has extracted the same.

In the present case the operating or guard lever 19, of the arm carries and operates the lock and actuates the boltand feed mechanism. The operating lever is carried by a slotted plate or frame q, fitted in the under side of the hollow receiver and secured therein by screws 0', this plate being also secured to the stock. The operating lever is formed to fit snugly against the under side of this lock plate or frame q with the inner portion of the lever extending inwardly through the slot of the frame. The form of the lever is substantially L-shaped, the inner end of the lever forming a heel 5, extending inwardly at an angle. The rear end of the belt at its lower edge is hinged at s, to the front upper end of this heel. The portion of the operating lever within the lock frame is slotted or formed of two separated plates to receive the hammer t, and cooking hook to.

The hammer t, is pivoted at its lower end to the lower end of the upward bend or heel of the operating lever and is located within the same with its upper end directly in rear of the firing pin in the bolt. The hammer thus works in and between the sides of the operating lever. mer is provided with a shoulder v, engaged by the upper end of the trigger guard to. This trigger guard forms the main spring of the lock and is rigidly secured at its rear end to the front end of the handle portion of the orerating lever and from thence extends around the trigger a and up with its free end engaging said shoulder of the hammer, hence when the hammer is pulled back it is operated against the tension of the guard by forcing the free end of the same down. The

The lower end of the ham-' trigger a is provided with a light spring I) forcing its upper end rearwardly. The trigger extends through the operating lever and is pivoted in the same and its upper end within the open space of said lever in the path of the hammer is beveled rearwardly and provided with a rearwardly facing sear hook or catch 0. The hammer at the upper portion of its rear edge is provided with a corresponding downwardly facing catch or hook d as shown beveled on its outer edge. The operating lever is provided with a movable fulcru m consisting of a link or lever e pivoted at its rear end in the rear portion of the frame q and at its other end pivoted in the rear end of the opening in the operating lever, hence, when the operating lever is swung down and forwardly the entire lever moves down and its upper end moves back in an approximately straight line to move the bolt. A cocking hook u, is pivoted at its rear end on the inner side of said link 6 and has its outer end beveled and its hook extending inwardly and of greater width than the space between the sides of the open part of the operating lever. The upper edges of the sides of the operating lever are curved downwardly and rearwardly from the heel thereof to form the cam edges f; hence, supposing that the arm has just been discharged, the operating lever is thrown down, the bolt is drawn rearwardly extracting the cartridge, the lower edges of the rear end of the bolt sliding on the upper edges h of the frame q holding the bolt in the proper position, the link e also swings down pushing the free end of the cooking hook up the inclined edges f, toward the hammer which at the same time is moving rearward until the hooked end of the cooking hook engages the cooking catchi' in the upper end of the hammer at the rear edge thereof and facing upwardly. The operating lever is then at its limit of downward movement and the bolt is entirely withdrawn from the loading chamber in the receiver so that a cartridge can be inserted or the magazine belt rotated. The operating lever is then drawn back to its normal position and as the distance between the fulcrum points of the hammer and cooking hook increases the hammer is drawn back by said hook against the tension of the main spring until the cocking hook reaches the lower ends of said curved edges f and the hammer continues to move directly down. The upper edges of the operating lever then throw the cooking hook from engagement with the hammer, and the hooked sear of the trigger immediately catches in the sear catch d of the hammerand the operating lever is pressed home to its normal position, the hammer is cooked and the bolt has forced the cartridge into the firing chamber and all parts are in readiness for discharge.

The simplicity and great reliability of this lock are obvious. The lock is composed of a' minimum number of parts and yet is positively sure and reliable. The parts successfully operate even when exposed to rust and dirt as there are no small, delicate or complicated parts.

The operatinglever is provided with the usual loop handle as shown although of course the invention is not limited to the use of such a handle.

A spring j is secured to the front end of the frame qso that the free end of the spring will engage the front edge of the operating lever when said lever is nearly forced to its seat and will exert longitudinal pressure on the lever so as to force the same against the under side of the lock frame and prevent the same from dropping. When the lever is thrown down the front edge of the lever passes back and down out of engagement with the spring. The spring acts to hold the lever p, yieldingly up in locked position so that it will not drop by reason of jars or blows. When the lever is thrown up to its seat the pivotal point between the lever 19 and link e is thrown above a horizontal line passing through the pivotal point between the frame (1 and the link 6' and the spring j pressing rearwardly and longitudinally against the front end of the lever yieldingly holds the parts in this position-as the lever in moving down first moves forward against the tension of said spring and then moves down away from the spring. This spring is located at the side of the lock frame and has an end j extending inwardly to engage the front edge 7' of the lever, see Fig. 8. The rear end of as a repeating or magazine gun.

the bolt is usually reduced in thickness so that when the cartridge has been forced into the firing chamber the' rear end of the bolt can be thrown up against a solid shoulder in the upper wall of the receiverforming a stationary recoil abutment. The recoil is thus transmitted directly through the bolt to this rigid shoulder, and all parts of the lock are free from the recoil and shock.

The gun as so far described is not adapted The cartridge can be inserted by hand in the firing chamber or placed in the groove in the bot tom of the loading chamber and the bolt will carry the cartridge into the firing chamber and then discharge it.

The magazine or repeating attachment consists of a series of cartridge holders Z hinged together at theiredges so that the holders all lie parallel and form an endless belt or chain with the two end holders hooked together. This belt ormagazine attachment can be of any desired or suitable length, and is passed through the transverse loading chamber in thereceiver and the two end holders, one havingthe hook and the other a bar, are united to form the endless belt which passes through said loading chamber and hangs from the bottom thereof. Each holder is slotted longitudinally on its under side so that the guide rib of the bolt can pass through the slot as the bolt forces the cartridge from the holder into the firing chamber and then draws the cartridge back into the holder after discharge. Each holder is made of spring metal so asto yieldingly hold the cartridge and permit the bolt to push through the same to carry the cartridge into and out of the holder. These magazine or repeating belts can be'formed and secured togetherin anysuitable manner, and can be very easily carried on the person and quickly attached or detached. As soon as a belt or series of holders is discharged the belt containing the discharged cartridges can be removed and a belt of loaded cartridges substituted therefor. The cartridges after they have been discharged are drawn back into their respective holders and hence are retained for future recharging.

Suitable mechanism is provided operated by the movement of the lock to feed the belt around, one holder at a time. This feed mechanism preferably consists of a plate 2, secured rigidly in the bottom of the space in the receiver beneath the casing or shell forming the bottom of the transverse loading chamber. This plate is provided with upwardly projecting end lugs 3, in which the ends of a transversely swinging plate at are mounted. This swinging plate extends longitudinally of the base plate and is arranged to swing from the left side of the base plate upwardly. A pair of angle levers 5, are located preferably on the right hand side of the swinging plate beneath suitable guides 19 and are pivoted together at 20 at orabout the center of the plate, so that when said levers are swunginwardly their outwardly extending fingers 6 will slide in beside the swinging plate and within the guides 19 and when the levers 5 are pressed out the fingers will. project beyond the plate through the openings 7 in the left hand side of the shell g, between two holders of the magazine belt, and as the swinging plate is turned to the right the belt will be drawn through the load opening the width of one holder. A rock shaft 8 parallel with the swinging plate is journaled thereto in rigid arms 21, extending outwardly from the right hand side thereof. This rock shaft has two lateral arms 9, 9,connected bylinks 10 10, respectively withlevers 5 5. This rock shaft is provided with a crank arm'll extending laterally from the end of the rock shaft to the left hand side of the swinging plate where it is provided with a lateral end or knob 22. It will thus be seen that when the crank arm 11 is raised the fingers 6 6, are first thrust out through the openings in the shell 8 into the belt,and when the fingers passout their full length the swinging plate itself is swung to the right carrying the fingers to the right and thereby moving the belt the proper distance. tained by pivoting the plates in the lugs 3, 3, and by having the rock shaft 8, journaled in rigid arms from the plate. When the crank 11 is pressed down the fingers 6 are first drawn in from the belt and then the plate is swung back to the left to its lowered position in readi- This swinging movement is atness to again feed the belt. The fingers in moving back are withdrawn entirely from the belt so that the belt is moved in one direction only in the present drawings to the right. The crank 11 is automatically operated by the lock mechanism. A lever 12 is fulcrumed at 24 on one side of and lies against the lock frame. One end of this lever is forked or notched at 25, and loosely fits the lateral end 22 of the crank 11 to operate the same, and the other end of the lever is provided with a stop 13 on its upper side. The upper edge of said lever forms a cam edge so that as the operating lever forces the bolt forwardly the lug 14 on the end of said bolt will engage the raised portion at the front end of said lever and will force the lever down thereby withdrawing the fingers and throwing the plate back, then, after the gun is discharged the operating lever is thrown down and the bolt drawn back to replace the discharged cartridge. The lug engages the rear raised edge of said lever thereby throwing the fingers out and feeding the belt forward before the bolt is again forced forward.

The advantages of this invention will be obvious to those skilled in the art.
