RECOIL-OPERATED FIREARM.

SPECIFICATIONforming part of Letters Patent No. 533,911, dated February 12, 1895.

Application filed July 10, 1894. Serial No. 517,117. (No model.)

.To all wm it may concer-n: I

Be it known that I, ARMAND Mine, a subject of the Emperor of Germany, residing at Heidelberg, Baden, Germany, have invented a certain new and useful Improvement in Firearms, of which the following is a specification.

The improved arm makes available therecoil which is produced by the action of the powder in tiring. To open t'he breech, extract and eject the empty cartridge-shell, cock the gun, insert a cartridge from an adjacent magazine, move it into position, and again close' and secure the breech, the operator has only to pull the trigger. The invention relieves him from a great portion of the 'shock ordinarily induced by the recoil and allows a calm holding and an accurate aiming of the weapon.

The'invention consists of improvements in the mechanism to promote the convenience and the-'safety of the nser, which improvements will be fully 'described below and specifically defined in the claims.

VThe invention may be applied to all sorts of {ire-arms and of any caliber; not only arms for military service, butalso pistols, hunting-pieces and target rifles.

The accompanying drawings form a part of this specification. They represent the invention applied to a pistol, and show the novel parts with so much of the ordinary parts as is necessary to show their relation thereto.

Figure 1 is a vertical longitudinal section partly in elevation, showingthe parts in the condition ready for firing. Fig. f1 is a corresponding section showing the parts after firing has occurred and the barrel and its attachments have moved backward by the recoil. Fig. 3 is a corresponding section showing the condition after the ln'eech-block has been moved rearward andthe barrel and its attachments have boencanried forward again nearly to the former position. Fig-i is a corresponding view showing the rear end ot the barrel and its .attachments with the breech closed but not locked. Fig. 5 is a section partly in elevation showing some ofthe parts as sccnvfrom the opposite side, in the same condition as in Fig. 4. Fig. 6 is a plan View ot the receiver.

Figs. 18, 1S, 1Sb and 19 show modifications. Fig. 18 is a front ViewT of a locking dog which serves to retain the hammer reliably in its locked and in its unlocked position. Fig. 18a is a view of the same from the right. Fig. 1Sh is a view of the same from the let't. Fig. 19 shows a further modification. Itis a central longitudinal section of a portion ofthe barrel and adjacentparts when the invention is applied to a long barrel, as of a musket or rifle.

Similar letters of reference indicate corresponding parts in all the figures where they appear. l

The arm is constructed with two principal parts, the stock or body carrying the cock and trigger mechanism, which part is to be held by the operator, and the barrel and attached receiver and magazine, rigidly connected together, and carrying the other portions of the mechanism. This barrel and connected case or receiver and magazine, which I shall refer to collectively as the carriage, is capable of moving lon gitndinall y Withn the stock. The mechanism is accessible by removing certain covering portions..

The barrel r of the pistol is provided at about its mid-length with an annular enlargement or collar 1"* which is favorably condi- ASi:

ICO

tioned to allow the hand to aid in opening or closing the breech when such shall be necessary. By the recoil due to the firing, the barrel with its attached receiver l) and magazine box a, moves rearward in the stock d.. The mechanism insures that this movement shall bend a stout spring o, the resilient action of which spring again drives forward the barrel, and its attachments'. The barrel is screwed into the front part of lthe receiver b, and the magazine box a is formed in one piece with the latter. The upper portion of the receiver b is formed with an aperture serving for the insertion of the cartridges, which are stored in a series one upon another in the magazine d below. In the interior of the receiver b are longitudinal grooves c4 one on each side, as shown in Figs. 6 and 7.

The breech-holte is adapted to slide longitudinally in the receiver b. Vertical grooves are provided in the receiver b and in the guides c, at each side of the breech-bolt c, which receive a forked operating lever s, which turns on a pivot s set in the carriage and serves as a means for communicating the required motion to the breechfbolt The front of the breech-bolt carries ordinary extractors c5 for removing the empty carl tridge-shell and ejecting it through the open top of the receiver b. See Fig 8.

The striking or firing pin c6 is adapted to move to a small extent longitudinally within the bolt c, impelled by a blow of the hammer received on a projecting spur.

The striking pin cG is provided with a rigid lateral arm or tooth z. ln the last part of the forward movement of the breech-'bolt, this tooth z strikes against a stud h2, carried on the hammer h, and thereby arrests the forward movement of the firing pin, in the act of closing the breech.

In the forward portion of the carriage is the locking-piece k, carrying the two parallel arms or double-locking bolt lo', 7a2, guided by the vertical grooves before referred to. The requisite vertical movement is given to this piece k at the proper time, through the medium of a closing lever il turningl on a pivot i', set in the carriage and moving backward and forward therewith. The longest arm of this lever, lies ordinarily parallel to the breech-bolt c, and engages by a slot i4 nearits forward end with the pin 71:3, on the locking plate k. The arm 112 extending downward, is provided with a stud i3 at its lower end, with which in a certain position of the parts the unlocking hook n can engage.- lSlee Fig. 4. A backward extending arm i5 iscurved as shown. In case the locking-bolt 7c shall not be completely' moved up into position, this arm t5 will stand in such position that the forward projection h2 of the hammer will engage over it and induce the completion of the movement of the locking lever before the iringis effected. In case the movement of the locking bolt has not progressed so far, or has not commenced, the arm of the/hammer will so engage the recessed arm i5 as to completely arrest the hammer and prevent the discharge. The pin t" set in the carriage a serves as a center for the lever and also as a means of,

attachment for a link q, which connects to (the upper end of a lever Z, pivoted on the center h set in the stock, and which performs important functions. This lever connects by a link Z3 with the spring o, before referred to, the considerable force of which tends to turn this lever in the direction to restore the carriage and the attached' barrel again to their forward position after each/recoil. The lever Zcarries by a pivot on its lower arm Z', a lever n, n', the front end of which has a hook-form, and serves as the locking hook before referred to, by taking hold of the stud i3 on the lower arm of the lever fi. The opposite end n of this lever strikes the pivot pin g at the proper time and disengages the hook the latter having been relieved from the force of the spring fwhich is mounted in the interior of the stock, and serves to hold the hook in engagement during the period required. The pin Z on'thelower arm of the lever Zalso carries pivoted on it a piece M which I will term a catch, having considerable longitudinal and vertical dimensions.

It is provided with a` long nearly horizontal slot m having an oj set m near its mid-length, which receives a pin s3 set in the side of the operating lever s. The bottom of this catch is equipped with a rounded projection m2, which, at the proper time, strikes against a pin s2 carried in the lower end of the lever s, and lifts the catch M sufciently to disengage the odset fm from its hold on the pin S3.

The lever sturningon the pivot s mounted in thel carriage, is provided at its upper end with an open fork s, by which it embraces the pin c3 of the bolt c, and is able to impart the required longitudinal motion. It is inserted into the recess in the slot in the bolt c from below,-the fork allowingl forthe circular motion. It is moved backward at the proper time to open the breech by the engagement of the odset m with the pin s3. This movement occurs immediately after the barrel fr with the accompanying carriage a, b, has moved forward. This rearward movement of the bolt c is effected rapidly,and the extractor c5 moves the empty shell which remains in the barrel after the preceding discharge, and ejects it through the opening in the top of the case b. See Fig. 6. The certainty that this will result is increased by a shock which is received through the lever s immediately after the discharge. This shock is in the nature of a concussionI due to the liberation of the hinged lever s6, which is secured to the lever s by the pivot si". There is a shoulder above such pivot which holds this lever s so that it cannot approach nearer than a certain angle to the lever s, but it may yield downward indefinitely. A spring S7 urges this lever s6 smartly upward. When the barrel lr and its attachments move forward in closing the IOO breech the lever s* is received undera pin ss iixed in the stock d.

charge,

When after the disthe barrel r and its attachments move rapidly rearward by the recoil, the curved upper sur face of the lever sG acting on the pin S8 depresses the lever s6 in opposition to the force of the spring S7.

Near the termination of the rearward movement the lever s6 escapes from its contact with the pin ss, and is moved 1o smartly upward by the The nature of the uni force of the spring S7. on transmits a smart shell, so that when c at a later period the bolt is moved rearward, the removal of the shell by the ordinary extractor is facilitated.

The cock orvhammer pivot h before referred to,

3o by a link i with a sufficiently strong spring fu, so

connecting a 71, is centered lon the and is actuatedv on its rear side as to pivot give the required blow on the striking pin whenever it is liberated by the action of the trigger. It is provided with a segment or arm 3,5 extending forward and end a projection h2,

carrying on its front and also with an varm extending backward provided with two recesses The lower portion of the cock is roundedand provided with an oiset'or sear 4o notch h5.

Into this notch engages the front end t of fa barring lever or sear t', t2, which turns on the same pin g The rear arm d, which bend stands directly over the detent t4,

acting on the rear endof the sear disengages 5o its front end t' from the sear notch h5 and I liberates the hammer, which then, under the strong action of the spring o turns smartly on its pivot h and striking against the firing pinv c6, explodes the cartridge. The detent t4,

5 5 after effecting its work,

may rise upward ineffectively to any distance, but it is again promptly brought dow n by the action of a suitable spring t7 on relaxing the pressure of weapon with the parts the linger on the trigger. v

Asa precaution against the workin g of the improperly placed, as

a premature or incomplete opening or closing of the breech action, the `pin k? in the side of the locking bolt is guided in a trapezoidal f)5 gl'OOV@ yi the stock ignate the several port see Fig. 14h-formed in the face of adjacentto the carriage.

I will desions of this groove by `is in the super-numerals, ment is such that the downward movement of the bolt k cannot take place untilthe carriage 2l', y2, 2l, if. The engage,

and consequently the pin k3 has moved to the extreme rearward position ind need by the rev coil. With the commencement of the forward motion of the carriage in restoring the barrel and its associated parts to theirv ring position, the pin k3 is moved downward by the tilting of the lever 'L'. lAfter the pin k3 has moved downward to its fullest extent, the carriage moveslforward for something like a half of its entire motion, carrying the pin k3 for- Y Near the termination of the forward motion the lever c' is rocked in the opposite direction, raising the pin k3 again -v to its original position. 1t will be observed that the pin k3 describes a trapezoidal figure, of which the front and rear sides are inclined in opposite directions and the'top and bottom are parallel, but the top is longest. The trapezoidal groove y corresponds exactly to that mot-ion and it is so placed as to coincide with the traverse of the pin k3, and said pin is elongated so as to always stand in such groove. The groove is of no effect so long as all the parts moire properly, but in case of any derangement' of the action due to a want of completeness of any movement or a loosening or breaking of any part, the groove y will arrest the action until the parts/can be restored to their 4proper working condition.

To prevent a premature striking there is arranged as shown in Fig. 15, a safety lever p, with connecting rod 193, which latter form of a ring, and is arranged to be operated at will. The'springq4 acting on the rear end of this lever urges it into such position that a lateral projection 102 on its forward arm p, will engage in one or, the other of the recesses h3, or h4, in the rearward arm of the hammer h. Engaging inthe forward arm h3, it holds the hammer in the cocked poof the cock,

sition, and forbids the piece being discharged.

Engaging inthe rearmost notch h4,it holds the hammer in the discharged position and prevents its being cocked. It follows that with,- out a previous operation ofI this lever by operating on the lever p5, the weapon can neither be charged nor discharged.

My weapon employs still another safety device, which prevents the striking pin from' a premature forward movement which might IIC be caused by an accidental shock or blow.

When the hammer is cocked the stud h2 of the front segment rises so high as to stand before a lateral arm or tooth z of the firing pin or striking pin c6. By the striking of this arm z against this projection h2 on the hammer, the firing pin is arrested. 'Vhen by any force the firing pin is urged forward, while the hammer still remains cocked, the piece cannot be fired because of the engagement 0fthe arm e' with this projection or stop h2. Instead of this constantly actingsafety device there may be employeda safety contrivanee regulated by hand. This is shown in Fig. 18.

In this modification there is provided on one side of the lock a safety wing 194, which by an eccentric shaft, penetrates into the interior of the lock. This shaft is so situated that the notches h3, h4, of the rear segment of the cock can be engaged by this safety wing. See Fig. 16. This modification of the locking device is shown in dotted lines holding the hammer in the cocked position.

Fig. 17 shows in dotted lines, the hammer with the safety device holding it in the discharged position. L

The combined working ot' the mechanism is as follows: In Fig. 1 is shown the position of the working parts in respect to one another when the weapon is charged and ready for firing. The breech-bolt or closing bolt cis forced tightly against the cartridge chamber in the rear of the barrel. The locking bolt 7c is in its highest position and bars the breech action. The hammer 71, is in the correct position and is retained by the engagement ot the safety stop p2 in the notch h3. The projection or stud h2 of the hammer is before the tooth s of the firing or striking pin, and the detent t4 of the trigger is beneath the bow t2 at the rear end of the scar t', t2, while the front end is engaged with the notch or offset on the hammer body and retains it with thespring o ready to effect the discharge. The lower arm Z of the lever Z is so farback that the pin s3 is received in the forward endy of the slot m. The closing lever i maintains a horizontal position parallel to the line of the barrel. In the recoil of the weapon the barrel and the parts rigidly united thereto, composed of the magazine a, and the receiver b, which collectively I term the carriage, are by the recoil caused to make a backward movement. Fig. 2 shows the condition of the parts after this backward or rearward movement is completed. The receiver Z1 has struck against the top of the hammer and pushed the same back, and allowed its offset h5 to be engaged by the front arm t of the sear. lhe lock is now cocked. The link q has turned the lever Z into the position inclined the opposite to that which itoriginally held, and the spring o o is exerting its force to return this lever and its attachments to their original position. The hook on the front arm of the lever n, it', is before the stud or lateral projection i3 on the lower arm 'i2 of the-lever i' and the piece M has moved into its extreme forward position so that the pin S3011' the lever s is received in the extreme rear end of the slot m. rlhe cartridge loosener s has been detached from the pin S8, having been depressed rearward by such pin in the active movement of the parts rearward during the recoil,and has Arisen under the influence of its spring si, and

been violently arrested by the shoulder near its pivot S5, communicating thereby a smart shock to the lever s, and consequently to the bolt c with the effect to loosen the cartridge shell. As soon as the action of the recoil ceases, the releasing action of the bent 5seen spring o, acting through the link Z3 on the lever Z, commences to turn this lever back to its original position, and to drive the magazine with all the united parts, (the carriage,) back into the position shown in Fig. 1. The unlocking hook n, is held by the springf before the nose i3, and by its curved end n presses on the shaft g. As the turning of the lever Z, and the consequent movement forward of the carriage progresses, the hook n retains the lever arm Z2, and causes the lever c' to turn around its pivot i', whereby the lever arm t' and the locking bolt k are moved down, and the breech action is unlocked. A p

little later the further turning of the lever Z, and the consequent rearward movement of the unlocking lever n, n by the contact of the rear end n with the pivot stud g, see Fig. 3, disengages the hook n from the stud 3, and liberates the lever 1'. This lever andthe connected locking bolt k, remain ineffective during all the middle portion of the forward movement of the carriage; but the continued rearward movement of the pin Z', and consequently of the catch M, engages the olsetm in the latter with the pin s3 in the lever s, and causes the lever s to turn actively rearward carrying with it, the previously liberated breech block c and the firing pin c6 mounted therein. This movement by the ordinary operation of the extractor c5, faeili tated by the previous loosening, brings with it the empty shell of the cartridge previously fired, and it is ejected from the cartridge case. Next the series of cartridges in the front portion of the magazine, shown by dotted lines in Figs. l, 2 and 3, are moved upward by any ordinary or suitable means, not

shown, so that the uppermost of the unused cartridges is brought into line with the barrel. The forward movement of the carriage conv tinuing, the parts again assume the position shown in Fig. l. In this movement the catch M is lifted by the engagement of its nose m2 with the pin s2. This movement liberates the pin s3 from the offset m and leaves the lever s and the breech bolt c at liberty to be moved forward. These parts are thus moved by the continued pressure ofthe nose m2 against the pin s2, whereby the continued movement rearward of the catch M turns the lever s on its pivot s', carrying the upper end and the bolt connected thereto forward. Then this movement has su fliciently progressed, the pin s3 reaches the curved portion of the slot m and allows the catch M to rise further, so that the nose m2 can pass over the pins?, and the further forward movement of the carriage, and the further rearward movementof the catch M can he completed. Near the termination of the forward motion of the carriage` the upper arm or shoulder is ot' the closing lever 'Z will strike a pin i9 fixed in the stock, and compel the turning of the lever into its original position, moving the locking holt k upward to engage reliably in the recesses in the breech bolt c. Near the close of the forward movc- IOO IOS

ment of the breech, the cartridge loosener s moves downward past the short pin 5*. The passage may be facilitated by beveling the contact parts. The weapon is new again ready for firing.

All the parts are so adjusted that the several operating movements take place in the,

proper succession, and atthe proper period.

In orderto take out the cartridges unused, the breech action may be opened by moving back the barrel, and the attached carriage by the force of the hand. The barrel is equipped with a collar fr to facilitate this movement. The several motions of the parts-may be the .same as before described, as when the barrel 1s thus moved by the recoil after the discharge. ysuch opening the cartridge which at the preceding closing was forced into the barrel, is drawn ont and ejected. The weapon may be used for single firing by moving the barrel back by its collar to open the breech. After inserting one cartridge the barrel is left free and the breech action is closed by the means previously described. For thus working the lockis retained in the open positionv by ,means of `a special barring mechanism, which `may as shown in Fig. 5, consistof a slide with two end buttons a', m2, and a sprlng x3. rl`he button :r2 by its pin penetrates through the receiver b and engages in a hollow made in the guiding rod ofthe breechV closing bolt. It bears against the narrow side of this hollow and prevents an advancing of the breech closing bolt until this pin'has been drawn ont ofthe hollow. Thenthe closing bolt may be driven forward, and the weapon be ready for firing.

In order to indicate tothe operator that the cartridges are spent, and that the magazine 1s empty, a plate on which the cartridges in the magazine are placed, may at the opening of the `breech action, after the last shot'V is tired, enter into the receiver b and hold the carriage against being forced forward until aV new chargent cartridgeshas been supplied. Modlfications may be made without departf ing from the principle or sacrificing the ad` u Although I have vantages of 'the invention. shown this mechanism asapplied to a pistol, it may be used with shoulder arn1s,guns, the different parts being stio'ngeland larger. Instead of the Ilat spring o, I can use a spring in a spiral or various other forms. Such spring may act on the linkq. Another arrangementwould be to place a spiral spring on the fore part of the barrel fr, urging the barrel and itsattachments forward. Fig. 19

shows such an varran gementf-*the forward end of the spring abutting against a cylindrical ring rr, which is screwed'upon the barrel.'
