MAGAZINE-GUN.

SPECIFICATION forming part of Letters Patent No. 366,512, dated July 12, 1887.

Serial No. 240,678.

(No model.)

To all whom, it may concern.-

Be it known that I, ARTHUR WILLIAM SAVAGE, a subject of the Queen of Great Britain, residing at New York, in the county of New York and State ofNew York, have invented certain new and useful Improvements in Magazine Guns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same. I

My invention relates to that class of magazine-guns in which the magazine is located in the rear stock.

The main objects of the invention are to provide a gun adapted to be used either as a magazine-gun or as a single loader, which shall be simple in construction, effective and reliable in operation, and easily manipulated; and to these ends the invention consists in the construction, arrangement, and combination of parts, hereinafter particularly pointed out in the claims.

In the acce mpanying drawings, which shall illustrate my invention and form a part of this specification, Figure 1 represents a view of the rear stock and frame of my gun, the stock being shown in section, and the side plate of the frame being removed to show the breech mechanism, the latter being in position as when the breech is closed. Fig. 2 represents a central longitudinal section through the frame, breech mechanism, stock, and magazine, the breech mechanism being in posi tion as when the breech is open. Fig. 8 is a side elevation of the frame and breech mechanism with the side plate of the frame removed, the parts being in the same position as in Fig. 1, the view being taken from the opposite side. Fig. 4 is a side elevation, and Fig. 5 a plan view, of the breech-block. Fig. (3 is a side elevation of the breech-block cover or cartridgeguide. Fig. 7 is a plan view of the cover or cartridge-guide. Fig. 8 is a rear elevation of the upper end of the operatinglever, looking from the rear, showing also the dog for cocking the hammer. Fig. 9 is a vertical transverse section through the frame on V the line a; m, Figs. 1 and 2, the view being taken from the rear. Fig. 10 is a transverse section through the brcech'block and cover or guide atthe line yy, Fig. 2. Fig. 11 is a similar section at the line .2 2, Fig. 2. Fig. 12 isa perspective view of the detent for holding the front cartridge between the breech-block and cover while the breech is open and until the parts are brought to the proper position in the closing movement to guide the cartridge into the chamber; and Fig. 13 is a section 011 the line 1 1, Fig. 2.

The breech system to which I have applied my invention is substantially that known as the Martini-Henry, in which the breechbloek is hinged or pivoted at its rear end in the frame of the arm, its front end swinging 6 in a Vertical plane to open and close the breech.

Referring now by letter to the accompany ing drawings, A designates the breech-block, and B the breech-block cover or cartridge guide. The breech-block is composed of the body portion a and two side arms, a a, which extend rearward from the body, and which are perforated to receive the cross-bolt which secures the breech-block in the frame, and upon which it swings in the usual manner. The body a of the breech block is bored out to receive the hammer a, which consists of a .tion of a dog, a, by which it is cocked, in a manner to be hereinafter explained.

The cover or cartridge-guide B is of a length and width to fit the mortise in the frame of the arm in which the breech-block works. Its 8 5 rear end through nearly half its length has a sufficient vertical thickness to allow a channel to be formed therethrough for thepassage of the cartridges as they escape from the mega zine, the said passage being in line with and 0 forming a continuation of the magazine when the parts are in their normal positions, as when the breech is closed. I

The rear end of cover or guide Bis cut away at the sides to allow it to enter between the 5 arms a c of the breech-block, and it is hung upon the same bolt or pivot with the breechbloek,so as to swing therewith. It has, however, a limited independent movement, as will be hereinafter explained in describing the op- IOO eration of the arm. The top part of the cover overhangs the 'sides, as shown in Figs. 10 and 11.

. At the rear part of the vertical enlargement of the cover,on both sides,below the pivot,are lateral lugs 12, which form shoulders, against which the arms 0 c of the lever O bear when thelatteris turned forward,whereby apressure is exerted to draw the cover and breech-block down into the position indicated in Fig. 2. Forward of the lugs b, and on both sides, are cavities or recesses b,which receive secondary arms 0 0 when the breech is opened. These secondary arms 0 c" perform no function in the opening of the breech, their purpose being to throw the cover up into position in advance of the breech-block, which they do by bearing against the front walls of the recesses b of the cover B. The closing of the breech is effectedthe upper arm of which projects into a slot in the projecting stem of the hammer a, as-shown in Fig. 2, and the lower arm of which has a notch or detent with which the trigger engages. \Vhen the lever C is turned forward to open the breech, the dog 0 turns with it until the trigger engages the notch in its lower arm, whereby it is retained in that position when the lever is returned and the breech closed. As soon as the breech-block begins its closing movement it swings forward and away from the dog 0, and as the hammer is held by the dog and cannot follow the forward movement of the breech-block it is drawn out and is held in that position until the dog is released by the pull upon the trigger, when the hammer is thrown forward by its spring,carrying with it dog 0. i

In order to increase the efficiency of the arm by facilitating the extraction of the spent shell after firing, I provide two extractorsor rather an extractor and an ejector-the office of the first being to start or loosen the shell and of the other to throw it out of the arm.

d designates the extraetor,and d the-ej ector. As illustrated in the drawings, the extractor d is on the left-hand side and the ejector on the right-hand. The extractor is fulcrumed at e on a screw or pivot that is inserted through the side of the frame. It has a long rearwardly-extending curved arm, which occupies the space between the side wall of the frame and the front end of the breech-block. \Vhen-the breech is opened, the end of the curved arm is struck by the overhanging side of the cover B, whereby the extractor is turned upon its pivot to start the shell, the force available for this purpose being proportioned to the relative lengths of the two arms and the distance of the fulcrum from the chamber.

The ejector (1 has its fulcrum at 6 below that of the extractor d. It has also a rearwardly-extending curved arm, which stands in the path of and is struck by a downwardlyextending arm, b at the front end of the cover B. The vertical arm ofthe ejector being much longer than the rearwardly-extending curved arm,it follows that when the latter is struck by the arm I) a quick blow is imparted to the shell, which, after the latter has been started and loosened, is sufficient to throw it entirely out of the arm.

The cover B is longitudinally cut out or re cessed along its side immediatelyunder the overhanging top for the reception of the bar F, which lies flush with the side of the cover. It hasits fulcrum atf, and-its rear end is pressed down by aspring, f, which is seated in therecess in rear of the fulcrum f. At the rear end of the bar F is a laterally-projecting arm,f which projects through an opening intothe cartridgepassage formed through the enlarged rear end of the cover B, as represented in Fig. 2. At the outer end of the armf is a tooth or detent, which engages the flange of the front cartridge after it has entered between the breeclrbloek A and cover B, (see dotted lines in Fig. 2,) and retains it until the parts reach the proper position during the closing movement to guide it into the chamber. The means for releasing the cartridge to allow it to be fed forward into the chamber will now be described.

to shoot forward into the chamber, its place being taken by the next one in the column. The fulcrum fis so arranged that but a slight movement of the cover B is necessary, after the teeth f (1 become engaged, to release the cartridge, and so soon as this is effected a cam on the front end of the'cover acts upon a similar cam on the extractor and presses the latter forward, when the bar F is returned by the springf to its normal position relatively 'roo to the cover B, when the detent isin position to hold the cartridge, which is then between the breech-block'and the cover, until the gun has been fired and the shell ejected, when it is released and fed forward,as already explained, and is succeeded by the next one in line.

Cartridges have been exploded in the magazines by the impact resulting from the recoil of the arm in firing or from handling; and in order to avoid all liability of such explosions it becomes necessary to provide means for holding the cartridges apart in the magazine while the gun is being fired or manipulated, and for this purpose I have devised the following instrumeutalities, viz: In a groove in the stock below the magazine I locate a toothed bar, G, the teeth g of which project into the magazine through suitable openings in its under side. These teeth engage the flanges of theseveral cartridges in the magazine and hold them against forward movement, and they are so spaced that the cartridges are held slightly apart to prevent the bullet of one cartridge from striking the cap or primer of the preceding one. The bar G has both longitudinally reciprocating and vertical movements relatively to the magazine, these movements being imparted by the following means: In the lower part of the stock is a socket, H, which receives the rear end of the operatinglever C. On the top of this socket, between suitable ears, h, is pivoted a bent or angular lever, h, the upper end of which is pressed forward by a spring, h, between the lower end and the socket-plate. This lever 71. extends into a notch, g, in the side of the bar G.

\Vhen the breech is closed and the end of the lever O is pressed into the socket H, it strikes the under side of the lever hand turns its for ward end upward and backward, whereby the bar G is raised against the pressure of springs 9 which are attached to the upper side thereof and press against the magazine-tube to throw the bar down when released by the withdrawal of the end of lever C from the socket H in the act of opening the breech. This upward movement causes the teeth 9 to enter the magazine and engage the flanges of the eartridges. After this is effected the continued movement of the lever carries the bar backward, and by reason of the spacing of the teeth, as already described, slightly separates the cartridges and holds them in this separated position till released by the withdrawal of the lever 0. As soon as thelever O is withdrawn the spring 72? rocks the lever h, throwing the upper end forward, whereby the bar G is also carried forward and is permitted to be pressed down by its springs gto liberate the cartridges in the magazine, in order to allow them to be fed forward by the niagazinespringto charge the barrel. In order that the last cartridge may be fed into the chamber, I place an auxiliary piston, I, in advance of the main piston in themagazine, which auxiliary piston is smaller than the main piston in order that it may follow the cartridge between the breechblock and cover or guide B. This auxiliary piston has a stem, 1', which projects through the main piston, andissurrounded and pressed forward by a light auxiliary spring, 2', which surrounds the stem 2. IVhen the magazine is filled with cartridges, the auxiliary piston is pressed back, its spring being lighter and weaker than the spring of the main piston; but when the main piston reaches the end of the magazine-tube, where it is arrested by a slot, the spring 41 expands and throws the small piston forward to drive the last cartridge into the chamber, the spring 2" being of sufficient strength for this purpose.

As a means for retaining the end of the op crating-lever in the socket H, I show an annular spring, h, which fits upon the outside of the socketand has at its center a projecting tooth or catch, h, which projects through an opening in the side of the socket (see Fig. 13) and engages a notch in the end of the lever when the latter is pressed home. The ends of the spring h yield to allow the tooth or catch to be pressed out when the lever enters or leaves the socket, and by their resiliency again draw it back when free to do so.

The magazine is charged through an opening in the lower partof the frame, which opening is provided withasliding door, J. It is charged when the breech is open, as represented in Fig. 2, by introducing the cartridges successively head foremost through the chargingopening into the channel between the breechblock and cover and pressing them back till their flanges are caught by the detentf The last cartridge inserted remains between the breech-block and cover till released during the closing movement of the parts, when it is pressed forward into the chamber of the gun, as already explained.

The operation of the arm is as follows: The magazine being charged and the breech-block closed, as represented in Fig. 1, when the lever C is thrown down to open the breech, the bar G is released and is thrown forward and downward by the action of the springs h g". This releases the cartridges and leaves them free to be moved forward by the action of the springpiston in the magazine. The breech being fully opened, the spent shell or the cartridge, if the gun has not been fired) is extracted and thrown out. Then as the breech is being closed the cartridge between the breech-block and cover is released by the action of the extractor upon the bar F, and is pressed forward into the chamber. \Vhen the breech is fully opened, the trigger falls into engagement with the dog 0 and holds the latter. Then as the breech is being closed the hammer is drawn back and the arm is cooked and ready for firing as soon as the breech is fully closed.

\Vhen a cartridge is inserted by hand, as in the case of a single-loader, the extractor is pressed forward by the flange, and the tooth (Z thereon is carried out of the path of the tooth f at the endof thebar F, and the breech is closed without tripping the detent and releasing the cartridge between the breech-block and cover. I The gun may therefore be used as a single-loader as long as or whenever desired, while the magazine is held in reserve. To close the breech without charging the chamber, press the extractor forward with the thumb or finger while the breech is being closed. This enables the gun to be carried or put away in an unloaded and uncocked condition.
