.magazine-gnns; and it consists in the arrangement of various devices to operate the breech mechanism, whether attached to a single or .double gun, or whether operating singly,

doubly, or simultaneously, and devices to cook the hammers independent of the breech-operating mechanism, together with other arrangements and combinations of parts, hereinafter more fully set forth and described. '20

Similar letters of reference indicate correspending parts.

opening between the fore-arm and frame. L is a starting-lever.

F indicates a rod for cocking one of the hammers. A duplicate thereof may be used for the other hammer.

The frame Ais constructed broad enough to carry two bolts, B" and B", (see Fig. 9,) and their locking mechanism, which may be similar to that shown in Fig. 8, or any that may be operated by the handles, substantially as here shown.

A rod, as R, is arranged on either side of the gun. It may be on the outside of the frame when I prefer to protect it by a cover, or in side, and it may reciprocate parallel with the bolt or obliquely to move the bolt in any of the known methods, some of which I have shown and claimed in previous applications.

The rod R has a lost motion in its engagementwith the breech bolt and brace, (see Figs.

5, 6, and 7,) which show a pin in the rod entering a slot in the brace and bolt. This lost motion enables the unlocking of the brace before pressure is brought on the bolt.

To operate the bolts separately by two slides, I connect one with a handle forward of the frame and the other to another handle to the rear of the frame by their respective rods, so that the two handles shall not interfere or be in the way of each other in operating.

It is obvious that both handles may thus I work in the same direction; but I prefer to reverse the movement of one of them that the operator may be less liable to make the mistake of firing one barrel for the other.

In Fig. 1 I show the rod R provided with cogs and engaged by the reversing gear-wheel W, which is engaged by the ratchet-rod S"'. Said rod S, being attached to the sliding has; die S, serves to turn the lower part of wheel \V forward, thereby rotating back the top of said wheel to move back the rod It by the forward movementof the slide S, and the forward end of rod R thus moves so far rearward that the rod 3" may pass obliquely forward and upward-forwardof the end of rod R without striking it. The belt on the other side of this gun is operated by a fore-arm, which is arranged with bearings (as barrel and magazine) forward of the frame to slide thereon, and said fore-arm is connected, as shown in the first figures or otherwise, to the breech mechanism,

so that a sliding longitudinal'movement of the fore-arm shall unlock, move,"and lock the breech.

In Fig. 1 I connect the sliding fore-arm to the breech by a rod, as B, so the back and forwar movement of sai rod when operated by the liding fore-arm moves the breech-piece back and forth in the same direction as the hand operating it.

In the modification, Fig. 3, the shield S is fixed to the sliding stock, so as to telescope back over the frame when the fore-arm is moved back, as there shown, and said shield carries a ratchet-bar, as R; and a cog-wheel, W, is pivoted to the forward end of the frame in position to be engaged by the ratchetbar 3", and in turn to engage cogs on the rod R, which connects with the breechmechanism, so that, moving forward, the sliding handle moves the rod 1% and breech-piece backward to open the breech by operation of the reversing-wheel W, and the backward movement of the fore-arm closes the breech in a' similar manner.

The fore-arm is made in the usual form, but

arranged to operate as a sliding handle, as described, and the metal shield S is provided to cover the opening between the sliding tip and frame when the fore-arm is in its forward position. v

In Figs. 1 and 3 the shield S" is seen fixed to the sliding fore-arm to telescope over the frame; but in Fig. 2 the said shield is attached to the frame and the tip slides inside of it, and the opening between the tip and frame is covered substantially in the same manner. I pivot a starting-lever, as L, Fig. 1, to the sliding handle S, and fix one or more shoulders, as l 7, in the body of the gun, for the upper arm or arms (here shown in dotted lines) to bear against in the last part of the movement of the bolt forward, or when in position to be started back, when allowance may be made for lost motion, as shown.

The lever L is provided with a handle, L,

' which is pivoted to the lever and to its bearing in the slide, so that said handle may be turned up against the bottom of the gun to be out of the way,,as shown in Fig. 1, without turning the operating end of lever L; but when the handle L is turned dowfi to the position shown in dotted lines thespring-cateh d snaps into the notch or depression (2 of the lever to fix the handle firmly to the lever for operating it, and the catch (1 may then be engaged by its projecting stud to pull it down out of the depression d of the lever, so the handle may turn up out of. the way, and the spring.

stud (1 then entering aslight depression on the side of the lever L or on the sliding handle thereby holds the handle L from falling.

The jointed lever described my be used to advantage as an operating lever or in the positions usually occupied by operating-levers, which move and lock the breech mechanism of magazine-guns, and the spring-catch may be in the form of a scar to hold but one way,

the other way of turning being'stopped by a shoulder on the lever.

A modification of the starting-lever of Fig. 1 is shown in Fig. 2, where L is the lever, l and Z its engaging points, which remain below the line of their fulcrum 1 when the lever is turned up against the bottom of the gun, as shown, or when turned down against the guard, as indicated in dotted lines, so it may slide past the fulcrum Z in either position without engaging it; but if turned either way to a position between the two shown, one of the engaging p ints will be thereby raised to engage the fule um Zto si art the slide either way, as desired.

A frietioirbearing holds'the lever in either po- G, as before; but the engaging points Z and Z are here shown as the ends of a doubleacting pawl, which is pivoted in the lever and engages for a fulcrum the fixed ratchet-bar Z, and a spring thumb-piece, L, is attached to the pawl and arranged iii the lever to pull the for ward point, 2, of the pawl out of engagement with the fulcruin-bar, so that by working the lever back and forward the rear point, I, only will engage the cogs ofthe-bar 1, and thereby force the guard-slide forward; butifthe spring thnmb-pieee-Lof the pawl be pressed upward it turns the point Z. of the pawl out of, and the point I. in to, engagement with the ratchet-bar, so that the vibrations of the lever will force the sliding guard rearward.

' The sliding guard (,l, as shown in Fig. 1, has a pin at its forward end, which travels in a slot in the frame to guide it, and said guard is pivoted at g to the sliding handle or section of a sleeve, S, to allow the guard to follow the curved. under side of the gun, while the bandle follows the straight line of the bottom of stance, which will give good-traction to the hand of the operator, which requires some degree of clasticityfand also a poor conductor 0f 4 20 heat, that it maybe easily handled whether cold or hot.

In Fig. 10 I show a cross-section of the sliding forearm handle, which has an inner inetallic part, in, to serve as a bearing and a sup- I port between the soft outside 'fore-arm, S, and

the magazine and barrel. The fore-arm S, as also the part 1 of slide S, may be made by molding material in a soft or plastic state upon the base of support m and afterward hardening it thereon.

The scar t is so arranged that it can only be engaged by the trigger i when the sliding handie S is in the position that insures the closed and locked position, of the breech, and thel trigger has a. projection, as t, which extends l laterally to guide the trigger along the way or ledge t" until it passes the tixed locking-shoulder t, when said projection it rises behind i and against the shoulder i by the same pull that forces the trigger up against the sear t to l release the hammer, so that at the instant of l l the discharge of the gun the trigger will be 011- gaged against the shoulder t to lock the guard and operating-handle in their rearmost position or from moving in either direction. It will be readily seen that by this construction i (as in Fig. l) the trigger may be pulled by constant pressure when the sliding handle S and i guard are being moved backward, (and the pressure on the trigger will help or produce that movement,) and fire the gun by the same pressure when the breech shall reach its closed position and lock the handle, until by the operator changing the movement to a forward one he releases the trigger so the handle becomes instantly frceto move forward and open the breech.

lhe loading-trap T, Fig. 2, and indicated in broken lines in Fig. l, vibrates onthe side of the frame in a similar manner to that shown in my Patent No. 250,880; but may swing down instead of upward to avoid the rod 1t, which closes the said trap by engaging the upright T. I

In the cross-section, Fig. 9, I show the ar-. rangemcnt of the bolts B B in this double gun. .The ribs :1 enter grooves in the frame to guide the bolts, and the rib of one bolt enters a longitni'linal groove in the other bolt to guide each and hold both in proper relative position whether they move together or separately.

The rod F,1*ig. S, is provided with aspring to retire it rearward, the forward end, of said rod taking a position rearward of the projection f on the hammer below its pivot, so that when the rod is forced forward bythe shoulder of the operator, or the gun is forced back by its recoil, the rod F strikes the proicction or notch of the hammer by its endf I -to rotate and cock the hammer, when the} .f, so that the hammer may fall or be caught by rounded rear portion of the hammer above 5 the pointf, having rotated so far downward as 5 tostrike the top of the rod F, presses it down to release it from engagement with the projection the sear atfnll-cock, and the hammer may be caused to fallby releasing the soar in the usual manner whether the rod F remains in its forward or rear position; but it bet-ween the two positions the rod inight obstruct the falling hammer, which Iprevent by hanging a lever, F, (see Fig. 8,) which has alate al projection at its rear to travel in the grom 3f, which is out in an extension which projects from the rod F, and the forward end of lever 1" extends to a position to be engaged by the trigger when it is pulled, so that in pulling the trigger to release the sear it also turns the rear of lever F downward to force down the point of the rod out of thc'path of movement of the projec tion 7'.

The rod F has a weight attached to it to stop (by its inertia) the rod aml cook the hammer when sufficient recoil takes place in firing the gun.

\Vhen both handles are used on onebreechpicce,it is not necessary that both be connected to the same part ofthe breech mechanism 0 in the same manner, or that they each have the same limit or length of movement, as one handle may move the whole distance to open the breech and [he other-only operate as a lever,or otherwise, to start the breech open in forccthe breech home in closing, or both.

Instead of the doublepa'wl in the lllOtililClln lion of Fig. ll, a singledog may slide in the lover and be'projected by the thumb-piece I), to cngage'the ratchet-bar to move the sliding handle, said-'dog being retired out of engage ment with the bar by a spring, as the spring of the thu llllbl'lltt't) L, and a continuation upward of the pier-e L may serve as the above dog, the

spring remaining as here shown; or a section of a ratchet-wheel may supply the place of-thc pawl ordo c and maybe retired by aspringpr turn out of engagement with thebarin a Sillll lar manner to that shown by lever L, Fig. 2.

1 do notclaim the projection formed by lever L, .as shown, on the sliding handle in Fig. 1 a; a pistol-grip, as I claim a pistol-grip in such connection in myapplicatiou No. 168,358, filed June ll, 1835.
