MAGAZINE FIRE-ARM.v

SPECIFICATION forming part of Letters Patent N o. 379,794, dated March 20, 1888. Application filed September 16, 1887. Serial No. 249.836. (No model.)

To all whom, tm/ty concern:

Be it known that I, HERMANN LEINEWEBER, a subject of the Emperor of Germany, residing at South Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement'in Magazine Fire-Arms, of which the following. is a specification.

My invention relates to the class of breechloading re-arms in which a magazine is provided to contain a number of cartridges which are fed successively tothe barrel and firing mechanism. I

It is my object to provide a breech-loading magazinegun which, .when supplied with its ammunition, shall be entirely self-acting with each discharge to feed another cartridge to the barrel and'iring mechanism, and simultaneously introduce the empty shell of the previously-discharged cartridge into a magazine provided to receive it. The attainment of my aforesaid object presents as advantages a gun in which there is no liabilityof premature or unintentional discharge, which may be discharged repeatedly andin succession as rapidly as desired without requiring it to be removedY from the shoulder, wherebythe aim need not be lost, as in other guns of the same class, in which the feeding of the cartridges to be fired and the expulsion of the empty shells are produced by mechanism requiring manipulation independently of the trigger. It also enables me to provide a mechanism involving, as compared with other guns of the same class, a simple, durable, and compact construction, involving parts none of which are liable to be come broken or i mpaired by even severe usage, and it afiords means for storing the shells of discharged cartridges, thus enabling them to be saved and used over and over again. This feature of economy, as an incident of my improvement, I regard as one of great importance, considering the cost of the shells, and it may be practiced` as will be understood from the description hereinafter contained, without inconvenience; or the mechanism may be readily arranged to expel the cartridges after iring them, when it is not desired to save the empty shells, as -in case of war, or of the employment of inexpensive shells, as of paper.

My invention consists in combining, with the mechanism for moving the cartridge into position for firing and with the tiring mechanism, a trigger actuating, through the medium of a single pressure, both said mechanisms consecutively in the order given-namely, first, the cartridge-adjusting mechanism,'and, secondly, the firing mechanism.

' My invention further consists in a magazine fire-arm having a magazine, an elevator to re c`eive the cartridges successively from the magazine, and a trigger connected with the elevatorand operated by. a single pressure to actnate the elevator to carry a cartridge supported by it to the barrel and firing mechanism and subsequently actuate the firing mechanism to explode the cartridge.

My invention further consists in a magazine lire-arm having a magazine provided with an automatic feed for the cartridges, a magazine for the shells of vthe exploded cartridges, an elevator to receive the cartridges successively from the feeding-magazine, and a trigger connected with the elevator and operated by pressure to actuate the elevator to carry a cartridge supported by it tothe barrel and firing mechanism and to actuate the firing mechanism to explode the cartridge, and by its release to return the elevator to its normal position,with the empty shell in position to enter the magazine provided to receive it.

My invention still further consists in the general construction of my improvement, and it also consists in details of construction and combinations of parts, as hereinafter more fully set forth.

In the drawings, Figure 1 is a broken longitudinal section of a magazine-gun of my improved construction, showing parts of my improvement, mainly in elevation; Fig. 2, a central longitudinal section of the same; Fig. 3, an enlarged section taken on the line 3 3 of Fig. 1, and viewed in the direction 0f the ar- 6 6 of Fig. 1, and viewed in the direction of roo the arrows; Fig. 7, a similar View taken on the line 7 7 of Fig. 2, and viewed in the direction of the arrows; Fig. 8, a view like Fig. 7, but showing the elevator raised to its highest position; Fig.A 9, an enlarged section taken on the line 9 of Fig. 2, and viewed in the direction of the arrow; Fig. 10, a similar view taken on the line 10 of Fig. 2, and viewed in the direction of the arrow; Fig. 11, a section taken on the line 11 11 of Fig. 12, and viewed in the direction of the arrows, and show-ing the construction of the exploded cartridgemagazine toward its forward extremity; Fig. 12, a section taken on the line 12 of Fig. 11, and viewed in the direction of the arrow; Fig. 13, a section taken on the line 13 13 of Fig. 2, and viewed in the direction of the arrows; Fig. 14, a view resembling that presented in Fig. 13, but illustrating by dotted lines the operation of the firing mechanism; Fig. 15, a section taken on the line 15 of Fig. 14, viewed in the direction of the arrow and enlarged; Fig. 16, asectio'n taken on the line 16 of Fig. 15; Fig. 17, a perspective view of a detail; Fig. 18, an end elevation of the trigger; and Fig. 19, a section taken on the line 19 of Fig. 2, and viewed in the direction of the arrow.

A is the gun-stock. having in its lower edge a slot, s, Fig. 6, extending from near the rear end of the stock to near the opposite end of the same, and provided on opposite 'sides throughout, near its entrance, with rubber strips s', which close it againstthe entrance of moisture and dirt. tudinal opening forming a chamber, r, in its right side, containing a lining, r', which incloses-a housing, r2, confined at opposite ends against longitudinal movement in the chamber and movable laterally toward its forward end on a pivot, at the rear end of the charnber r. A spiral spring, B, fits, when compressed as shown, into kthe housing r2, and is provided at its forward end lwith a head, q, to which is secured a pin, q', having connected to it one end of a finger or handle, qthe opposite end of which is bent, as shown, to extend through the slot s in position to be grasped.

At the rear end ofthe slot s is a transverselycurved slot,s`*, and at the forward end of the chamber 1 is a transverse slot, s3, which forms a lateral branchbf the slot s. On the inner side of the chamber 9', which is wider than the housing r2, is 'a spring, r, Figs. 3 and 4, tending to maintain the spring B and its carriage r2 norlnally in the position shown in Fig. 5, and on its outer or right side the housing 1' is hollowed out, as shown at w', to conform to the longitudinal section of a cartridge.

C is a cylindrical passage forming a cartridge-magazine, which leads from the forward open end of the chamber 'r through the stock and to the elevator D, hereinafter described.

The elevator D comprises a block (see Figs. 2, 7, and 8) having projections, as shown in Fig. 2, to lessen friction, bored longitudinally to coincide with the bore of the magazine C, and supported in a chamber, E, of the form shown in Figs. 7 and S-that is, in the form of an oblong square below and arched and contracted above. The yblock constituting the elevator, and whichcorresponds in shape with The stock has a longi! that of the chamber E, is split vertically along its center, and the two parts are loosely held together by pins p,passed transversely th rough them near opposite ends toward their bases. At opposite sides of the chamber E are plates F, having longitudinal lateral projections o near their upper and lower edges, which bear against the inner sides of the chamber E instead of having the entire outer surfaces of the plates bear against the sides of the chamber, whereby the plates may be moved with the least possible attendant friction, and at their rear lower ends the plates are connected by a cross-bar, F', from which a iinger-piece, F2, extends in a downward direction through aslot below the forward part of the magazine C, asshown. As will hereinafter more plainly appear, the parts F, F', and F2 form the trigger.

The pins p, which project at their ends from opposite sides of the block D, extend through shaped or inclined slots n, formed in the sides of the plates F, so that when the latter are drawn backward by pulling upon the iin-- ger-piece F2, the block D or elevatoris caused to rise upon the inclined planes n within the chamber E and cause the bore in the elevatorv D to coincide with the'gun-barrel G and firing apparatus, hereinafter described.

Immediately behind the upper part of the chamber E is a chamber, H, endingat its forward extremity in a narrow aperture, m, forming its communication with the elevator-chamber, and provided with upright partitions m and m2, which produce subchambers Z and Z.

I is a needle supported to be reciprocated in the partitions m and 1n?, which form its bear' ings, and provided on opposite sides with longitudinal recesses y and y', (see Figs. 14 and 15,) and the point of the needle extends normally through, but not beyond, the aperture m.. Between adjacent sides of the partitions m and m2, and surrounding the needle,are collars k and 7c having parallel horizontal guides k2, which fit into the recesses y and y', and a spiral spring, I', surrounds the needle and is confined between the collars k and k'. The rear end of the needle, which extends into the sub-chamber l', is recessed on its upper side, and contains in the recess a piece of rubber, h', and near the reas;` end of the needle is a collar, k3. A flat cross-bar, z', extends transversely through the end of the needle and through a tongue-piece, h, inserted into the recess to press against the rubber h', and carries on its cylindrical ends, which extend through slots i3, forward-extending fingers i', having lateral lugs on adjacentsides of their forward ends,which enter grooves or guides i* in opposite sides of a stationary cam, K; and the rear ends of the plates F, which are beveled, as shown at z, on their upper edges, engage with or abut against the forward ends of the fingers i'.

The forward ends of the plates F terminate in tongues F3, which extend along opposite sides of a metal casing or chamber, Gf, below IIO the barrel G,containing a metal core, G, '(see Fig. 19,) provided with a central cylindrical bore, g, extending nearly through it, having lateral opposite recesses g' and containing a spiral spring, i2, and the spring abuts at its rear end against a wall, g2, and at its opposite end against a plug, g, on a cross head or key, g, which extends at its opposite ends through the tongues F3. If desired, the casing G and core Gr2 may be integral.

Above the bore g in the metal core G2 and slightly to one side, Fig. 19, is a recess, f, containing at opposite ends springsf, upon which rests a fiat stri p, f l, confined in the recess f, and having a tongue, f 3, which extends vertically just beyond the base of a laterally-elongated bore, L, formed through the metal core G2. The bore L in crosssection is in the form of two semicircles joined above and below by straight lines. The right side of the bore L coincides with the bore in the elevator when the latter isin its normal -or lowered position, while the left side thereof coincides with a magazine, C', provided in the wood portion below the barrel to the left side of the center of the latter and closed at its forwardextrernity. T he right side of the bore L is also provided with a longitudinal slot, c, covered by the inner edge of a pivoted cam-block, N,with the outer edge of whichengages a lng, b, on the inner side of an adjacent tongue, F, when the trigger is drawn back, as hereinafter described. v y

As shown in Fig. 1 1, the magazine .C has an elongated opening, e, in its side near its forward end, toward the forward extremity .of which opening the inner wall of the magazine inclines, as shown at e', and the opening is provided with a cover, d, Fig. 12, in the form of a split tube, having a thumb-piece, d', and adapted `to be turned .behind the chamberO in a groove. di, to uncover the opening e.

The operation of my improved gun is as follows: First, the magazine() issupplied th rough the opening in the side of the stock A with cari tridges M, which are preferably formed with-l out circular heads at their rear ends, as shown, though the presence of such heads dors notinterfere with the operation of my device. To enable the magazine to receive the cartridges,

the spring B, which, when released and unobstrncted, extends to the elevator, must be compressed, which is effected by pnllingbackward on the finger q'2 and forcing the housing r2 against the spring r* sufficiently to tilt the block until the plug q coincides with asocket, a', Figs. et and 5, to one side of the entrance to the magazine C, when the spring B forces the plug into the socket, .thus permanently holding the automatic feed inoperative and freeing the entrance to the magazine, whereby the cartridges may be readily inserted one after the other, the succeeding ones being always used to force forward into the magazine the preceding ones. The cartridges are thus introduced one after the other until the magazine has been filled to its capacity, with an ad -ture m and bore of the barrel G.

A-ditional cartridge in the bore of the elevator D, and an empty shell, M', (or, if desired, another cartridge,) in the right-hand portion of the laterally-elongated bore L, which, as hereinbefore described, coincides with the bore in the elevator when the latter is in its normal or lowered position. When the maga- -zineis filled, the spring B is released by pull- `ing the head q out of the socket a,when the spring r forces it into its normal position, wherein the spring B exerts its resilient force against the cartridges to feed them automatically as they are fired, in the manner hereinafter described. To fire the gun,the finger F2 is pulled back, carrying with it the plates F, (or, in other words, the trigger, comprising the parts F, F', and F2, is pulled,) causing the pins p to rise in the slots n and raise the elevator Din the chamber E till the cartridge in the elevator is brought in line with the aper- It will be noticed that the two parts of the block forming the elevator D separate toward their upper sides when rest-ing on the base of the chamber E, thereby enlarging the bore and permitting the cartridge received by it, which, as quite commonly formed, is tapering toward its forwardend, and therefore enlarged toward its rear end, to enter the bore easily up to its enlarged extremity,- or to the iiauge, if provided, around its rear extremity; and when the elevator is :raised the two parts ofthe block forming it are compressed together,owingto the narrowing 'of the chamber E toward its upper side, whereby the cartridgeis firmly grasped and held against any possibility of movement during its explosion. Thecartridge is thus not fed to the barrel in the sense that it enters the same, as is, I believe, generally the case in magazine-guns, but is raised to and held at its opening until and during the discharge. W'hen the trigger is thus pulled back, the upper rear ends of the parallel slotted plates F abut against the for- 'ward ends of the fingers i', thereby forcing the latter back along the lower grooves or guides i* of the cams K, and through .them the needle I, thus compressing the spring l', and alsocompressing the rubber bearing h by the pressure against it of the tongue h on the rear end of the needle. The needle is t-hus forced back and thespring I compressed untilthe lugs or projections 2 attain positions behind the points a of the cams K, separating the lower from the upper grooves, (the beveled edges z of the platesF having meanwhile maintained co ntact of the latter with the fingers t" and permitted some lost motion with reference to the fingers,)when the resilience of the spring I suddenly forces the fingers forward in the upper grooves of the cams through the forward press- .ure exerted by it upon the needle, causing the Vof the rubber bearing h' against the tongue h on the rear end of the needle forces the for- IOO ward ends of the fingers t" down the forward grooves in the cams to the forward extremities of the lower grooves to prepare the mechanism for subsequent action. lThe mere recoil of the spring l does not alone project the point of the needle sufficiently far forward to cause it to penetrate the cartridge; but the momentum the needle receives bythe sudden expansion of the spring is imparted to the sliding collar k', which, when the spring I has reached the full limit of its expansion, compresses it from its rear end sufficiently to permit the needle to advance till the collar 7:" strikes the wall m2,( which is sufficiently far to cause penetration of the cartridge) when the backward recoil of the spring returns the sliding collar k to its place against the forward face of the wall m2 and frees from the cartridge and carries the needle back to its normal posit-ion for subsequent action. The pull on the 4trigger is exerted against the resistance of the spring I2, which, owing to the connection of the tongues Fwith the key g, is thereby comv pressed in a backward direction, so that when,

after firing, the trigger is released the spring I2, by its resilience, forces it back into its normal position, and, since the pins p follow the guide-slots n, lowers the elevator in the chamber E.

vIt will be remembered that a cartridge or an empty cartridge-shell, M', is confined in the right side of the elongated bore L, which,whcn the elevator is in its normal or lowered position, is in line with the bore in the elevator,where by the shell of the exploded cartridge would abut against that in the bore L, as aforesaid, were not means provided for shifting the lastnamed shell into the magazine C for theempty shells. As the trigger is pulled, the lug b, Fig. 9, follows the outline of the pivotal cam N, thereby turning it inward on its pivot and causing it to press the shell adjacent to it in the right sideof the bore Lover the tonguef", which is thereby eo mpressed into the left-hand portion of the elongated bore L, which coincides with the entrance to the magazine C', thereby'substantially emptying the right-hand portion of such elongated bore and preparing it to receive the shell of the cartridge last eX- ploded from the elevator, and which is forced forward by the automatic feed or spiral spring B in the stock A in supplanting it by a succeeding cartridge. The shell thus forced from the elevator has not, however, an unobstructed passage to the right side of the elongated bore L, since the shell previously forced from the latter, in the manner hereinbefore described, into the left side of the same presents a p0rtion of its end to the path of the advancing shell in the elevator, which thus forces the empty shell in advance of it from the left side of the bore L into the magazine C. The re coil of the spring l", which returns the tongues F3 of the plates F to their normal positions, slides the lug b against the cam N in a backward direction, thereby returning it also to its normal or straight position. It will thus be seen that the action of my improved gun consists, generally stated, in automatically feeding the cartridges successively to theelevator, raising the elevator to carry the cartridge it contains to the bore of the barrel and into position to be exploded by the tiringmechanism, actuating the firing mechanism, and shifting the shell of a previously-exploded cartridge to the empty-shell magazine, all of which is done by pulling the trigger, and by releasing the latter lowering the elevator to permit the automatic feed to introduce a fresh cartridge into it, whereby the shell of that previously exploded is forced intoa reserve chamber, at the same time advancing an empty shell in its path into the empty-cartridge magazine to make room for its subsequent admission into the same. The gun is not cocked or in a condition to be fired until toward the end of the pressure upon the trigger, and thus can not be prematurely or accidentally discharged.

When the magazine C becomes4 filled, the cover d may be turned to uncover the opening e, and by tipping the gun the contents will fall out, and may thus be saved; or, if it is not desired to save the empty cartridgeshells, the cover may be kept open, whereby the shells may be permitted to fallout as they reach the opening e, the bevel e' in which guides them thereto.

If it shall be desired to supplant each cartridge exploded immediately by a fresh one, instead of ring the entire contents of the magazine C and then replenishing it, this may be done by maintaining the finger q2 in the slot s2, thus locking the spring B permanently in its compressed condition, whereby a cartridge may be readily inserted for each one exploded by pressing the housing r2 to one side on its pivot a: in forcing the cartridge against the concave surface x', Fig. 5, of the housing, and the insertion or forward shoving of the fresh cartridge maintains the magazine filled and performs the function otherwiseperformed IOO yI IO by the automatic feed, as hereinbefore described. Thus, as will be seen, my device may be adapted for single loading.

I have shown and describeda needle as forming the active member of my improved firing mechanism. I do not, however, wish to be understood as limiting myself tosuch form of device for the purpose, as any of the forms of striking devices in common use may be adapted to my improved mechanism; nor do I desire to limit myself to details of my mechanism, as these may be variously modified without departing from the spirit of my invention.
