SPRING AIR-GUN.

SPECIFICATION forming part of Letters Patent No. 627,764, dated June 27, 1899.

Application filed Iuhe 26,1897. erial No. 642,363. (No model.)

To all whom it may concern.-

Be it known that I, MERRITT F. STANLEY, a citizen of the United States, residing at Northville, county of Vayne, State of Michigan, have invented a certain new and useful Improvement in Spring Air-Guns; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it than the piston-chamber, and the escaping air drives a pellet or missile.

The objects of the invention are, first, to provide such a gun with a catch mechanism adapted to hold the stock to the barrel in its closed condition, but a catch of such a nature that it will allow the easy breaking of the gun for the purpose of retracting the spring; second,to providealoading mechanism adapt ed to separate from a magazine which surrounds the barrel a single pellet and convey the pellet into the muzzle end of the gun, whence it drops by gravity toward the breech end of the gun into the choke at the inner end of the barrel, and, third, to provide an inner or lining shell that is split at one'side and is located within the stock end of the barrel in the vicinity of the trigger mechanism and is adapted to guide the rod of the piston when the piston is actuated in either direction.

In the drawings, Figure 1 shows the gun in longitudinal horizontal section. Fig. 2 is a perspective of the end of the muzzle, showing the loading mechanism. Fig. 3 is a perspective of the bottom of the muzzle end of the gun, showing the place at which the magazine is charged. Fig. 4 is a' side elevation, partly broken away, showing the gun in open position. Fig. 5 is a detail horizontal section of the rear of the piston-chamber.

At the breech end the mechanism for holdin g the stock in its closed position is described as follows: The barrel A is secured in the side pieces B bya screw b, that passes through the side pieces and a lug on the bottom of the barrel. Between the side pieces B and behind the trigger is held a dog D, which engages, by trunnion-ears d, in pocket-bearings in the side pieces. The dog is pressed upward by a spring a and at its free end terminates with a catch D. When the dog yields either in making engagement or in breaking engagement with the hook on the stock, hereinthe casting, which engages with the draw-link c, is provided with a catch 0, that'engages over the hook D on the end of the dog D. The engagement between the catch 0 and the hook D holds the stock to the barrel unless considerable force is used to separate them; but by the exertion of the proper amount of force the gun is broken, the parts turning on trunnions b and the stock serving as a lever to retract the link a, the rod C, and compress the spring C The rear end of the rod 0 terminates with a hook Z, that engages with the link 0, and in order that this hook may be guided properly I insert in the rear of the barrel, behind the piston-chamber, a lining or inner casing E. This is made of sheet metalbentintoanearlycylindrical form and having the two edges reenter at e 6', thus forming a raceway, into which the extreme end of the hook or rod 0 projects, and the rod is prevented from turning on its axis as it reciprocates in the chamber. The front end of this lining E serves as the rear abutment to hold the spring 0 in the piston-chamber. Y

The loading and the magazine charging mechanism is described as follows:

The magazine is a chamber between the ex tern'al casingF and the internal tube or barrel f. This chamber is capable of containing a number of pellets of lead of size suitable to be used as missiles in the gun.

On the bottom side of the magazine, slightly back from the muzzle, I provide a lug f, through which there is a hole f leading into the magazine. On the lug is a flat cover g, held by a pin or screw g, on which it is capable of turning. WVhen this cover lies parallel to the magazine, it closes over the hole f and when turned to one side it discloses the hole f and the magazine may be charged through this hole when the cover 9 is turned to one side. From the pin g a spring 9 extends forward and engages with the slide h.

On the front end of the magazine, arranged to slide axially partly across it, is a loadingslide h, held to the muzzle end of the barrel by two pins h 71 that pass through slots 70 7c in the slide. In the muzzle end of the gun are two holes,'one, j, leading into the magazine and the other, m, being the mouth of the true barrel.

The slide it is provided with an extending end 72, that engages with the end of the spring 9 and the slide is normally held by the spring in the position shown in Fig. 2, so that both the openings j and m are open; but there is on the slide it a saddle or carrier 7, that extends over the opening and is adapted to hold a pellet in the space between the carrier and the slotted prongs K K. In order that the pellet may not escape from the carrier, the outer end of it is recurved slightly, so that a pellet once engaged in it can escape out from it only by dropping either back into the magazine or into the barrel, and in order to transfer a pellet from the magazine to the barrel it is only necessary to hold the gun with the muzzle slightly depressed and the pellet will run into the carrier 9". The carrier is then pushed radially across the muzzle and the gun tilted, when the pellet rolls from the carrier into the barrel, and inasmuch as the rear end of the barrel is slightly choked the pellet is caught in the choke and held.

What I claim is 1. In a breakdown gun of the class specified in combination with the stock pivoted to the barrel-holding side pieces, a spring-actuated hook located between the side pieces arranged to yield with a motion which shortens the distance between the catch and the pivot on which the stock turns and a catch at the end of the stock adapted to engage therewith, substantially as described.

2. In a muzzle-loading magazine-gun in combination with the outer casing and the true barrel located within the outer casing, a carrier adapted to move radially across the muzzle of the gun provided with a saddle arranged to receive a pellet from the magazine and transfer it into the true barrel, substantially as described.

3. In a device for transferring pellets from the magazine to the barrel of a gun, the combination of a radially-movable carrier provided with slots, pins holding the carrier to the muzzle of the gun and a spring arranged to actuate it, substantially as described.

4. In a breakdown gun of the class described, in combination with the piston-chamber, a piston and an actuating-spring, a split tubular lining inserted within the pistonchamber, and having the edges of the slit recurved inward to form a raceway to guide the end of the piston-rod, the front end of the lining constituting an abutment against which the spring engages,substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.

MERRITT F. STANLEY.
