f aZZ whom it may concern! "Be it known that I, \VILLIAM B. FRANKLIN, of Hartford, in the county of Hartford and State of Connecticut, have invented new Improvements in MagazineFire-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 exactdescription of the same, and which :0 said drawings constitute part of this specification, and represent, in-

This invention relates to an improvement in that class of fire-arms in which the breechpiece is a part of a slidingbolt provided with a handle extending radially therefrom, and by which the breechpiece is drawn back ward in opening or forced forward in closing, and in which the breech-piece is secured by imparting to thebolt a rotation by means of the said handle, and particularly to those arms of this class in which a case containing cartridges may be applied over an opening in the receiver, so that cartridges will successively fall in front of the breech-piece when in its rear or open position and be forced into the cartridge-chamber by the forward movement of the breech-piece, the preferred case ormagazine being substantially that shown and described in Letters Patent No.'3l4,823, granted tome March 31, 1885.

The magazine is in length substantially that of the length of the cartridges to be employed, 4 and is constructed with partitions to form a circuitous pocket in which several cartridges, side by side or parallel with each other, may be introduced and arranged upon the barrel with the opening downwarthso that as one cartridge passes from the mouth of the magazine into the receiver others .in the column follow by their own weight, presenting successive cart-ridges to the opening in the receiver asthe lowest one is transferred to the barrel. 1

The object of the first part of .my invention" is to provide aseparating device between the column of cartridges and the receiver, so that it. is impossiblefora cartridge from the mega-- zine to pass into the receiver unless the re- 1 ceiver is clear or a'previousl y-introduced car tridge has been entirely removed, whereby choking of the passage is impossible.

In my patent before referred to the magazine is constructed with a flange at its forwardw and'rear ends adapted to engage corresponding transverse grooves at each end of the opening in the receiver, so that the flange at one end of the magazine is first introduced into the groove at one end of the opening in the receiver, and then the magazine is swung later ally to bring the flange at the other end into engagement with the groove at that end of the receiver. I find in practice that in firing the recoil has a tendency to throw the rear end of the'magazine from its seat.

The object of the second'part' of my invention is to make a dead-lock for the magazine s'; i motion of the tr gger, so that it the-trigger be when in place, and while the breech-piece is in its closed or firing position, so that by such lock not only is the magazine surely brought to its position to deliver a cartridge to the receiver, but so securely held that displacement is impossible from the act of firing.

The object of the third part of the invention is tomake the engagement between the ex tractor and the head of the cartridge in the barrel positive, so that escape after engagement is impossible until they are completely withdrawn,

The object of the fourth part-of my invent-Eon. is. to make an interlock between the breech-piece and the receiver independent of the handle, whereby the cam action for the final closing of the breech-piece and the first part of the opening movement for starting the cartridge may be produced in the receiver independent of the handle shoulder or lug.

The object of the fifth part of my invention is to provide a locking device which will pref'vent the accidental withdrawal of the breechpiece entirely from the receiver, and which locking device may be operated by an overpulled sufficiently far backward the breechpiece may be removed, but not otherwise.

A represents the receiver, to the forward end of which the barrel B is secured in the usual manner; C, the breech-piece, which is arranged to slide longitudinally in the receiver, the bolt of which is provided with a handle, D, by which the breech-piece may be rotated, and which handle works into or from a recess, E, in the side of the receiver, so that when the breech-piece is in the closed position the handle is turned down into the recess E and the breech-piece locked, or when the handle is raised from the recess and brought into avertical position the breechpiece may be drawn rearward for opening,the

handle passfiig through a groove in the top-0t the receiver to the open position, as seen in Fig. 2. This, being a common construction of arms, does not require particular description.

Upon one side of the receiver is a projection, F, which forms an enlargement of the cartridge-receiving chamber. (See Figs. 1, 2, and 3.) To the top of this enlargement of the cartridge chamber the magazine G is attached, as seen in Figs.3, 4, and 5, the magazine being in the form of a case, adapted to receive several cart-ridges parallel with each other,

and so that when in place the cartridges may roll by theirown weight downward to the mouth of the magazine, and the moat-lief the magazine,being directly over the enlargement of the receiving chamber in the receiver, will conduct the cartridges into their proper position in the receiver, forward of the front face of the open breech-piece.

The opening or mouth of the magazine is of a shape to permit the cartridge to fall through it into the receiver; but it is necessary that .end of the receiving opening,

the column should be supported independent ofthe cartridge in the receiver or of the breechpieee, so that the breech-piece may be moved backward and forward. To this end Iarrange a separator, H, in the receiver at the forward hung upon a pivot, 41, in the receiver opposite the magazine side, and so as to swing backward and forward in-a horizontal plane, as from the position seen in Fig. 1' to that seen in Fig. 2. When standing in the position seen in Fig. 1, the passage into the receiver is fully open; but when the separator H is turned rearward, as seen in Fig. 2, it extends into the opening and immediately below the mouth of the magazine, and so that the forward end of the lowest cartridge in the magazine will rest on the separator, as indicated in Fig. 2. At the rear end of the openingin the receiver is asecond separator, I, hung in the receiverupon a pivot, b, and so as to swing in a horizontal plane and in substantially the same plane as the separator H but so that when turned backward, as seen in Fig. 1, the opening into the receiver is free, but when turned forward, as seen in Fig. 2, then the separator I extends into the opening below the lowest cartridge, and so as to support the rear end of that cartridge. The magazine-month is only of a size to permit the free movement of a cartridge therefrom into the opening in the receiver, as seen in Fig. 3.

The separators are operated by the breechpiece. The forward separator, H, is constructed with a rearward and inward projection, d, from its hub end, which extends into a recess, 0, in the side of the breech-piece, as seen in Fig. 1. Vixen the breech-piece is in the closed position, the breech-piece also bears against the rear side of the separator H, so as to hold the separator in the forward position when the breech-piece is closed, as seen in Fig. 1; but upon the first partof. the rear movement of the breech-piece the forward end of the recess e bears against the projection d from the hub of the separator and acts as a cam thereon to turn the separator rearward into the position seen in Fig. 2, so that, one cartridge having passed from the magazine into the receiver and alongside the breech-piece, the separator H will pass above such cartridge In the receiver and immediately below theforwardend of the next cartridge in the magazine. Then, as the breech-piece continues its rear movement, a shoulder, f, in the side ofthe breech-piece engages a corresponding shoulder, 9, on the hub of the separator I, and as the breech piece continues its movement the shoulder f acts as acam upon the separator I and turns it forward over the rear end of the cartridge in the receiver and below the next above in the magazine, as seen in Fig. 3, so that the two separators hold the column of cartridges in the magazine suspended. As the breech-piece reaches its extreme rear position, the cartridge in the receiver then rolls into its place forward of the front face of the breech-piece, asindicated in broken lines, Fig.

2, so that when the breech-piece is again moved forward the cartridge will be forced into its place in the barrel, in the usual manner for this class 9f arms. The column of cartridges in the magazine will be held suspended until, as the breech-piece approaches its closed position, it strikes the rear face of the separator H and forces itforward into its closed posi- 10 tion, as seen in Fig. 1, and so as to leave the 'forward end of the first cartridge in the magazine free to drop into the receiver, and as the breech-piece approaches its closed position a second shoulder, h, on the breechpiece strikes a corresponding shoulder, 1}, on the hub of the separator I, and as the breechpiece completes its closing movement turns the separator I rearward into its closed position, as seen in Fig. 1, and so as to permit the.

rear end of the said next cartridge inthe magazine to drop-that is to say, when the breech-piece is in its closed position the mouth of the magazine is open; but immediately as the breech-piece commences its rear movement the separator H is thrown outward and so as to come. below the next eartridge'in the magazine and separate the column from the cartridge which may have passed into the receiver, and also turns the rear separator into a like position, so that the column. of cartridges in the magazine is supported while the breech-piece is open and until on its return it reaches its closed position.

As the breech-piece reaches its closed position the extractor engages the head of the cartridge which it has forced into the barrel, and so that when next the breech-piece is withdrawn the shell (or cartridge, if it be not exploded) will be withdrawn accordingly and pass rearward beside the cartridge which then lies in the receiving-chamber, and until the breech-piece has arrived at its extreme open position,when the shell will drop from its engagement with the extractor th rough an opening in the under side of the receiver, as in my patent hcreinbefore referred to, leaving the way open for the cartridge, which has fallen into the receiver from themagazine, to come into place forward of the front face of the breech-piece and in its turn be forced into its place in the barrel.

The shoulders which operate theseparators are formed iuthe sides of that part of the breech-piece which extends above the bolt and which moves backward and forward through the opening in the top of the receiver. The shoulders f and h,whieh operate the rear separater, I, are seen in Fig. 7. They are in line with the respective shoulders g i on the separator Ithe shoulder h above the shoulder f.

From the shoulder fa groove, 1, extends rear ward, and from the shoulder h a groove, m, extends forward, the two grooves forming a single groove between the two shoulders, so that the paths of the shoulders are one above the other. The shoulders g i on the separator the barrel and positively I are correspondingly arranged, as seen in Fig. 8.

As it is impossible that the separators can be thrown from their position supporting the column of cartridges until the breech-piece is completely closed, and so that its extractor shall have positively engaged the head of the shell or cartridge in the barrel'which it has forced therein, tridge cannot escape from the magazine into the receiver until the breech-piece has been so fully closed as to make engagement with the c'artridge'in the barrel, in doing which the separators are withdrawn from their support of the column and the lowest cartridge of the column will fall into the receiver beside the breech-piece and before the cartridge so falling can have passed to its position forward of the front face of the breech-piece. The separators are positively introduced above the lowest cartridge and below the column, so as to support the remaining column until this secondcartridge shall have been forced into withdrawn there'- from. 1 The'magaziuc G is constructed with a flange, n, projecting from its forward end, which is adapted to' pass beneath a transversegroovc, r, on the receiver. The edge of the flange and the groove are of correspondingly curved shape, as indicated in broken lines, Fig. 4, so that the flange n on the front end of the magazine is first. introduced beneath into its groove 1, which serves as a center uponwhich the magazine may turn. Then a similar flange, s, on the rear end of the magazine passes into a corresponding groove, t, on the receiver at the rear end of the opening into the receiver. This is substantially the same as in my patent before referred to.

\Vhen'the magazine is in proper place, its mouth stands over .the opening into the recciver and in proper relative position thereto, so that the cartridges mayfall from the magazine into the receiver, as before described. Owing to the interlocking character of the flange and groove at the forward end, that end is held firmly. To support the rear end, I introduce a springbolt, a, (see Fig. 4,'l which acts as a latch to engage the magazine when in its proper position; but as this latch must present an inclined nose, so that the magazine may be removed or inserted without mechanically moving the latch, the force of the recoil frequently tends to overcome the power of the latch and throw the rear end of the magazine outward, as seen in Fig. 4, thus loosening it from-its latch and rendering it liable to complete accidental displacement.

To insure the retention of the magazine in its proper position, I construct its lower edge with an inclined notch, '10, at its rear end, and on the brecehpicce 1 form or apply a corresponding hook, 3 (See Fig. 4.) In Fig. 4 the magazine is represented with its rear end slightly withdrawn from its proper position;

it follows that a second car-' but in such position the notch 10 stands in the path of the hook 3 on the breech-piece as the breech-piece approaches its closed position, and as the breech-piece completes its closing movement the hook 31 engages the notch 10, interlocks therewith, and draws the magazine to place, as indicated in Fig. 5, so that when the breech-piece is closed the magazine is positively locked in its proper posi'tion for delivering cartridges, and so that the recoil can have no effect to displace it; but as the breech-piece commences its opening-move U the breech-piece remains in its closed position.

It will be evident that it is desirable in the use. of this class of arms that the extractor should make positive engagement with the head of the cartridge, in contradistinction to simply a spring engagement. which is liable to escape from the cartridge if the cartridge offers sufficient. resistance therefor. To accomplish this desirable object. I construct the extractor in the form of a V-shapcd spring, L

representing one leg of the spring and M the other. The extractor is introduced intoa 1ongitudinal chamber, N, in the breech-piece. (See Fig. 9.) Preferably, at its rear end, the extractor is provided with a stud, O, which rests in an elongated recess, 1, in its chamber, so that while it prevents the extractor from being withdrawn from its chamber, itperlnits a certain amount of longitudinal play for the extractor.

The leg Mlakcs a hearing or seat in the forward end of the extractorchamber, but soas to leave the leg otherwise free to act as a part of the spring for the extractor. The leg L is constructed at its outer end with the usual bevcl-noscd hook, it, adapted to ride over the drop over the flange of the cartridge when the chamber-is fully closed. As the extractor stands in its rear position, as seen in Fig. 9, the extractor is free to rise to thus ride over the head of the cartridge. The extractor leg L is constructed upon its under side with a downwardly and forwardly inclined or hookshaped shoulder, S, and the bottom of the extractor-chamber is constructed with a correspondingly-inclincd hook-shaped shoulder, T. The longitudinal movement of the extractor is sntlicicnt to permit its hook-shaped shoulder S to engage with the corresponding shoulder, T, in the breech-picce,as indicated in broken lines.

If, after the extractor has made its engagement with the cartridge, the breech-piece be withdrawn and the cartridge ofi'ers any considcrable resistance to leaving its place in the barrel, the extractor will be held by the eartridge, while the breech-piece will move rearward until the shoulder T has interlocked with the shoulder S on the extractor. Then, because such engagement of the extractor with the breech-piece prevents the extractor rising, it cannot escape from the head of the cartridge. Consequently the cartridge must follow the breech-piece if the breech piece continues its rear movement. After the cartridge has been fully withd raw n and escaped from the-receiver, as before described, in the next advance of the breech-piece the nose of the extractor will strike the next cartridge under the force applied to the breech-piece, and the extractor willbe moved rearward out of its locked position, and so that at the proper time it'will be free to rise and pass over the flange of the cartridge, as before described.

In the usual construction of this class of arms the handle acis asa cam against the rear edge of the recess in the receiver, into which it to ms in looking the bl'('1l.-})l00, and so that-the handle itself is the .block to resist recoil. The handle D, as before described, is made substantially a part of the bolt U, the bolt being tubular and of thensual construction to contain the hammer and mainspring, as shown.

Upon the bolt, diametrically opposite the handlc, isa radially-projecting lug, V. (See Figs. 7 and 8.) In the receiverin the bottom of the recess, through which the bolttravels in opening and closing the breech-piece, is a longitudinal groove, 7, (see Figs. 6 and 10,) in which the lug V moves in the. backward and forward movement of the breech-piece. At the closing position of the breech-piece the groove W is turned to one side and upward to form a right-angular extension, Y, of the groove. (See Figs. 6 and 10.) The width ofthis extension of the groove Y corresponds to the length of the lug V upon the under side of the bolt; The turn from the groove \V into the extension Y is made of cam shape, as seen at 3, Fig. 10, against which the rear end of the lug V will work as the handle is turned to the locking position, and so that the lug V, working over this cam'shaped entrance to the extension Y of the groove, will operate to force the breech-piece forward to its completelyclosed position, and so that the lug V, with the extension Y of the groove, will serve to resist the recoil. Then in the opening movement of the handle the lug V will work against the cam-shaped forward end, 4, of the groove \V' and impart to the breech-piece the first part of what is called its "starting movement. This relieves the handle and the rear end of its recess in the receiver from the great wear which is brought upon it in the usual construction.

To prevent the possibility of discharge of the hammer until the breech-piece is substantially locked, I construct the hammer with the sear being hung upon a pivot, 17, an a forwardly-projecting arm, 6, upon its under as to be actuated by the trigger 18 to em side, (see Fig-9,) which extends alongthe' the cock-notches of the hammer in the u under surface of the bolt, and fromthe arm 6 manner.
