To all whom it may concern.-

Be it known that I, VILLIAM B. FRANK- LIN, of Hartford, in the county of Hartford and State ot' Connecticut, have invented new Improvements in Magazine Fire-Arms; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of [g the same, and which said drawings constitute part of this specification, and represent, in

This invention relates to an improvement in that class of breech-loading fire-arms in which the breech-piece is arranged at the rear of the barrel and in axial line therewith, and so as to be moved backward in opening and forward to close the breech, and to which a case containing several cartridges may be ap' 5o plied over an opening in the receiver, so that the cartridges will successively fall in front of the breech-piece when in its rear position, and be forced into the cartridge-chamber by the forward movement of the breech-piece, and also in which the breech-piece is operated by a handle forward of the receiver, beneath the barrel, arranged to move longitudinally backward and forward parts of the invention applicable to other classes of arms, the object of the invention being to adapt the arm to re- 6o ceive the case or magazine on the top of the receiver, the magazine being readily attached to or removed from the receiver as 'occasion may require, and so that the arni may be used either as a breech-loader or as a inagazine-repeater; and the invention consists in the coinbination of elements fully hereinafter described and particularly recited in the claims.

A is the receiver, to t-he forward end of which the barrel B is attached. In the re- 7o ceiver, in r'ear of the barrel, the breech-piece C is arranged in axial line with the barrel, and so as to move backward in opening the breech to the I position seen in Fig. G, or forward to close the breech, as seen in Fig. 8.

To the under side of the breech-piece the locking-dog D is hung upon a pivot, a, and so that when the breech-piece is forward the dog will drop'down in front of and againstashoulder, E, in the receiver, as seen in Fig. 3, and So so as to hold the breech-piecein its locked position, but so that when the dog is raised, as indicated in broken lines, Fig. 3, the dog escapes from the shoulder E, unlocks the breechpiece, and so that the breech-piece may then S5 be moved rearward, as indicated in Fig. 6. The upper face of the dog is recessed to permit it to' thus rise beneath the breech-piece, as seen in Figs.' 11 and 12. On the under side of the dog D is a downwardly-extending arm, 9o F, by which the dog is operated. Below the dog is a longitudinal sliding bar, G, arranged in longitudinal guiding-grooves b in the receiver, (see Figs. 3, 6, and 10,) the arm F extending down through an opening, c, in the 95 bar .G near its rear end, and as seen in Fig. 3. The bar G extends forward through the receiver beneath the barrel, its forward end passing through a guide, d, formed in the under side of a band, H, around the barrel and roo fore arm. To this bar a handle, I, is fixed, by which the bar maybe conveniently moved backward and forward, the bar guided by grooves bin the receiver and by the guide d at the .forward end. As the bar is moved rearward from theposition seen in Fig. 3 to that in Fig. 6 the rst part of the rear movement/raises the dog, as indicated inbreken lines, Fig. 3, to take it from its locking position and above the shoulder E. Then,the rear y movement of the 'bar G continued, the breechpiece will beforced to its extreme rear position, as seenin Fig. 6. On the return of the bar G by the forward movement of the handle the breech-piece will be forced to its forward position and the dog turned down forward of the shoulder E, and so as to lock the ,breechpiece in its closed position. .The shoulder E is formed in two parts, as seen in Fig. 12, the arm F of the dog passing between the parts of the shoulder in its back and forward movement.

Longitudinally through the breech-piece is the firing-pin L. This extends to the extreme rear, where it terminates in a head, M, upon which the hammer may strike.

In the breech-piece, above the dog D, abellcrank lever is hung upon a pivot, e, one arm, N, extending upward into a recess in` the breech-piece, the other arm, O, extendingforward, and so that when the breech-piece is in its closed position and the firing-pin forced forward under the blow of the hammer the arm O will hang down over orupon the dog D, and so that when the dog D rises, asin the first part of the rear movement of the bar G, it will strike the arm O and turn the arm N backward and force the firing-pin to retreat, as seen in Fig. 6. Thus the firing-pin retreats before the rear movement of the breech-piece commences.

P is the hammer, hung upon a pivot, f, in the usual manner, and so as to engage the trigger R when thrown to half or full cock, as seen in Fig. 6, also a usual construction.

As the breech-piece commences its rear movement a tongue, h, pivoted in the rear end of the breechpiece, strikes a corresponding shoulder, on the hammer and forces the hammer rearward to the full-cock position, as seen in broken lines, Fig. 13, at which time the tongue h escapes from the hammer, leaving it at. full-cock, the breech-piece passing on to its extreme rear'position, as seen in Fig. 6. As the dog D moves backward, carrying the breech-piece with it, it rides upon the under side, S, of the upper tang, which gives it a downward turn upon its pivot, until it arrives against a shoulder, Z, as seen in Fig. 6, which arrests the further rear movement of the breech-piece.

On the forward side of the hammer, and below the breech-piece, is an arm, T, concentric with the axis upon which the hammer rotates, the forward end of which rises as the hammer is turned to its rear position, and as seen in Fig. 6.

On the h ub of the iiring-pinlever ,O N is a shoulder, m, whichat the extreme rear position, strikes the end ofthe said arm T, which holds the lever O N in the position of retracting the firing-pin, notwithstanding the fact that the dog D has been turned down away from the arm'O. Thus the firing-pin is forcibly held in its' extreme rear position while the breech-piece is open; but as the breech-piece is moved forward the shoulder m will leave the arm T of the hammer; but as the dog D rises, following the upward curved surface from the shoulder Z at the rear to the lockingshoulders E, it will hold the lever and firingvpin, and so that when the breech-piece arrives at its extreme forward position the firing-pin will be left in its position of retreat as the dog D is thrown down into its locking position, and will there remain until the hammer is released to strike the firing-pin to deliver the blow of the hammer to the cartridge that may be in the cartridge-chamber of the barrel.

On the top of the receiver, and immediately in rear ofthe barrel, is an opening, U, corresponding 'substantially in shape to the cartridge for which the arm is adapted, and so that the cartridge may be introduced through the opening U to a position in front of the' open breech piece, as seen in Fig. 6. The opening U is narrower than the diameter of the head of the cartridge, but slightly wider than the body of the cartridge; but at the extreme rear end of the opening a recess, n, is cut in each side to Widen the opening at that point to the extent of the diameter ofthe head, and so that the head may drop down through the recesses n, as seen in Fig. 6.

Below the opening U the sides ofthe receiver are recessed, as at r r, Figs. 9 and 10, to forni a chamber or seat for the cartridge,and through which the head of the cartridge may pass in the IOO forward movement of the breech-piece to take the cartridge into the chamber in the barrel. Below this cartridge-receiving chamber is an opening, V, downward entirely through the receiver; but this opening is shorter than the cartridge, leaving a solid bottom, s, at the forward end of the auxiliary chamber, upon which the forward end of the cartridge will rest, and. so that when in the auxiliary chamber, as seen in Fig. 6, the forward end of the cartridge will rest upon this solid bottom s, while the rear end will be supported by the head lying in the recesses r r.

In the extreme rear position of the breechpiece, as` seen in Fig. 6, it stands to the rear of the head of the cartridge when placed in the auxiliary chamber, as seen in Fig. 6, the breech piece being prevented'from contact with the head of the cartridge by the forward end, t, of the extractor W. In this condition, as the breech -piece commences its forward movement the forward end of the extractorhook will strike the head of 'the cartridge and give to it a forward movement until, arriv- IIO IIO

ing the chamber will cause the hook to rise and pass over the flange of the cartridge, and so as to engage the cartridge, that when the breech-piece is withdrawn it may take the cartridge-shell with it, as seen in broken lines, Fig. 6. As the shell comes back with the breech-piece the head moves to a position considerably in rear of the position of the head of the cartridge when introduced into the auxiliary chamber, as before described, and as seenv in broken lines, Fig. 6. At this point the head of the cartridge passes into the recesses u, as seen in broken lines, Fig. 6. These recesses, as seen in Fig. 5, leave a space somewhat greater in width than the head of the cartridge-shell, and so that the head of the cartridge-shell, arriving at these recesses, may pass downward into the openingV away from the extractonhook, and so as to escape from the arm, the opening V being of sufficient length to permit such escape of the cartridgeshell. It will therefore be seen that as a cartridge is placed in the auxiliary chamber, as seen in Fig. 6, and preparatory to its introduction'into the chamber in the barrelythe head rests in the recesses r r in the sides of the receiver, so as to prevent its entering the opening V, and also to prevent its escape from the arm, because of the overhanging of the upper edges of the recesses r r; but when the Yshell is withdrawn from the chamber after explosion, or the cartridge if it be not exploded, the cartridge will be moved so much farther to the rear than its introduced position that its head will come into the recesses u, as indicated in broken lines, Fig. 6, and so that the shell, or cartridge, if it be not exploded, will fall downward through the opening V, and away from the arni.

The extractor shown in the illustrations is that for which Letters Patent were granted to C. B. Richards, August 18, 1868, No. 81,290, and in which the movement of the extractor in ridingover the flange of the cartridge and engaging it is made positive without the employment of a spring Near its rear end it is hung upon a pin, 10, there being a slot through the extractor to permit a certain amount of longitudinal movement of the extractor on the pin 10. In Fig. 6 the extractor is shown in the extreme forward position. Near the for ward end is a downwardly-projecting lng, 1l, inclined downward and forward on the front face, and in the breechpiece is a correspondingly-inclined shoulder, l2. As the breechpiece advances, the nose of the extractor will strike the head of the cartridge and force it rearward, as indicated in broken lines, Fig. 6, taking the inclined face 1l of the extractor away from its shoulder, and so thatin the advance ofthe cartridge into the chamber in the barrel the'eXtractor-hook will ride over the flange of the cartridge whenever the resistance to the entrance of the cartridge into its chainber is sufficient to raise the hook. Then when the breech-piece commences its retreat the cartridge or shell of the cartridge in its seat in the barrel will hold theextractor,while the breech-piece starts in its rear movement; but so soon as the inclined shoulder 12 strikes the inclined face of the lug 11 it holds the extractor down upon the cartridge, so that the cartridge or shell must follow the breech-piece in its retreating movement, the inclined shoulder locking, as it were, the extractor in its down or engaged position.

While illustrating and by preference employing the Richards extractor, it will be understood that the common spring-extractor may be substituted therefor.

As thus far described the arm operates as a breech-loader. 1 will now proceed to describe its adaptation as a magazine fire-arm.

The magazine 13, adapted to this arm, and which 1 illustrate, is a construction for which I have applied for Letters Patent, application Serial No. 135,232. It is arranged with several partitions, as seen in Fig. 10, alternately' extending from opposite sides, inclined downward toward the mouth 14, as seen in Fig. 10, so as to form a circuitous passage, which may be lled with several cartridges, and so that when the mouth is downward they will successively fall through the mouth as one is taken from the month. rIhe magazine is filled 'with cartridges with the mouth upward, and is then inverted over the opening U in t-he reeeiver, as seen in Fig. 10, and so that the cartridges may successivelyr fall through the mouth in front of the breech-piece when the breech-piece is in its open position.

The magazine is constructed with an outwardly-projecting flange, 15, at the forward end of the mouth, and a like projecting dange, 16, at the rear end of the mouth. (See Fig. 3.) The receiver is constructed with a horizontal groove, 17, atvthe forward end of the opening U, and a similar groove, 18, at the rear, these two grooves corresponding to the anges 15 and 16 on the magazine, and so that the magazine maybe passed in sidewise, the lianges entering, respectively, the grooves 17 and 18, and when in proper position the mouth of the magazine corresponds to the opening U, as seen in Figs. 3 and 10.

The magazine is constructed at one side of the mouth with a spring-tongue, 19, which, when free, turns inward, as seen in Fig. 9, and so as to serve as a stop to prevent the cartridges in the magazine from escaping, and so that the magazine filled with cartridges may be transported without danger of cartridges escaping. It is necessary, therefore, as the magazine is applied to the arm, to remove or displace the tongue 19, in order that the cartridges may fall from the mouth into the auxiliary chamber in the receiver. To this end the receiver is constructed with an upwardly-projecting lug. 20, (see Figs. 4, 9, and 10,) and which stands inthe path of the tongue as the magazine is introduced from one side.

The introduction of the magazine is indicated in Fig. 4 in broken lines, the iiange of the forward end being set into the groove 17,`

IOO

IIO

The rear endA is then turned to pla-ce in the groove 18. In so doing the spring-tongue 19 strikes the lug 20, as seen in Fig. 9, and as the magazine. approaches its place the springtongue is bent outward into a plane with that side of the magazine, as seen in Fig. 10, so that the mouth.. of the magazine is left entirely open for the escape of thecartridges, and each cartridge will escape therefrom into the auxiliary chamber below whenever that chamber is opened by the movementof the breech-piece. The rst advance or closing movement of the breech-piece forces the first cartridge into its chamber in the barrel. Then withdrawing it, the shell or cartridge, if it be not exploded, will escape through the opening V below. Then the next cartridge from the magazine will fall into place, and so on until all the cartridges in the magazine have been discharged. Then the magazine is removed and -a second filled magazine applied; or the magazine removed may be refilled with cartridges and replaced.

In order that the nextcartridge in the magazine may not interfere with the previous cartridge, which has fallen into the auxiliary chamber, in its forward or rear movement, I provide a check which will hold back the column of cartridges in the magazine until the breech-piece is fully open. This check 2l is in the form of a lever hung upon a pivot, 22, to swing in a horizontal plane directly above thebreech-pi'ece. (See Figs. 7, 8, and14.) The checlewhen the breech-piece is forward, stands over the breech-piece. as seen in Figs. 7 and 14, and below the lowest cartridge in themagazine, or across the mouth of the magazine, and

so as to hold back the column of cartridges.

On the under side of the check-lever is a Stud, 23,which rides upon, say, the right-hand side of a rib, 24, on the breech-piece, and this rib forms in shape a continuation of the extractor, and as seen in Fig. 7.

Near the forward end ofthe breech-piece is a diagonal groove, 25, across its upper surface and across the extractor, as seen in Fig. 7. As the `breech-piece approaches its rear position this groove engages the stud 23 on the check, and the continued rear movement forces the check from the position seen in Fig. 7 to that seen in Fig. 8, and to the position seen in broken lines, Fig. 14, the check entering a niortise, 26, in the side of the receiver prepared for it, and so as to leave a free passage between the mouth of the magazine and the auxiliary chamber in the receiver. When The inward movement of the check.

the upper cartridge awayfrom the cartridge in the chamber, as seen in Fig. 14, and so as to preventa clash between the flanges of the two cartridges, and also to prevent the breechpiece from striking the-head of the second cartridge, or any interference of said second cartridge in the working of the arm.

In this arrangement of the magazine, because of the opening into the receiver being directly inline with the breech-piece, the magazine will stand in the central line of the barrel, and would therefore be in line with the sights as usually arranged. I therefore arrange the sights at oneside of the central line, as seen in Fig. 2, so that the line of sight isto the left of the magazine, and as clearly seenin Fig. 2.

The tendency of the spring-tongue 19b'earingl against 'a lug, 20, on the receiver would be to turn the magazine from its place over the receiver, and this tendency will be increased to a considerable extent by the shock in firing. To prevent such turning out of place of the magazine, I provide alock forthe magazine. This consists of a turn-button, 27, hung in the side of the-mouth of the receiver opposite thelug 20, and as seen in Fig. 6,which, when the breech-piece is in its open position, as seen in Fig. 6,will stand down flush with the upper surface of the receiver at that point; but

in theclosingmovement of the breech-piece' The tongue h, hung in the rear lend of the breech-piece so as to act upon the hammer in its rear movement, permits the hammer to be thrown to a position to entirely escape contact with the moving breech-piece after the tongue has passed from the hammer, and so in returning there will be no conflict or-contact between the breech-piece and hammer, the tongue turning up to pass over the nose ofthe hammer in the forward movement of the breech-piece. This tongue, however, is the invention of another, and I make no claim thereto.

The longitudinally-movable extractor which I have shown and described possesses an advantage over an extractor made fast to the breech-piece without such longitudinal movement, first, that in its extreme forward posi- -tion it prevents the headv of the incoming cartridge from passing so far back as to come into the recesses u, which it might do in some cases if the head of the cartridge happened to be somewhat smaller than the standard size, and the extractor-hook is close to the rear end ofthe brcech-piece,as it must beif it be hung to the breech-piece, so as to preventlongitudinal movementthat is to say, when in its forward position, as seen in Fig. 6-it prevents such ICO IIO

possibleentrance of the flange of the cartridge I 3. In a fire-arm, the combination of the loninto the recesses u.

The stud 23 on the under side of the check, which works through the groove 25 on the upper side of the breech-piece and across the extractor as the breech-piece approaches its extreme rear position,will cause the extractor to move forward on the breech-piece untilthe lug ll comes to a bearing against the shoulder l2, so that if the breech-piece is opened when there be no cartridge-shell in the magazine to extract the forward movement of the breech-piece is insured before a cartridge can fall from the magazine or be otherwise introduced into the auxiliary chamber, and as seen in Fig. 6, and will there stand as a guard to prevent the movement of the cartridge in the auxiliary chamber rearward to bring its head within the recesses n. The check serves also to draw the extractor rearward into the position seen in broken lines, Fig. 6, on the first part of the forward movement of the breechpiece. In such movement the groove 25 lthrough the stud 23 draws the check inward, and as the stud passes into the groove in the extractor it will hold the extractor while the breech-piece moves forward, and until the extractor comes to its rear bearing, as indicated in broken lines, Fig. 6. This insuresthe freedom of the extractor to ride over the cartridgehead in the early part of the forward movement of the breech-piece and cartridge.

I have described the tongue 19 as a springtongue; but it will be understood that if the metal from which the magazine is made is inelastic the tongue will be simply bent in over the mouth of the magazine so as to prevent the escape of the cartridges from the magazine, and then when the magazine is set upon the receiverthe tongue will be bent outward, as shown.
