MAGAZINE` SPRING-GUN.

SPECIFICATION forming part of Letters Patent No. 429,106, dated Iaay 27, 1890. Application filed December 28, 1889. Serial No. 335,241. (No model.)

T0 all whom, it may concern.-

Be it known that I, ANDREW J. EMLAW, a citizen of the United States, residing at Grand Haven, in the county of Ottawa and State of Michigan, have invented a new and useful Improvement in Air-Guns, of which the following is a specification.

My invention relates to an improvement in target air-guns; and its objects are, iirst, to facilitate the loading of shot into the barrel of the gun; second, to prevent the shot from 4falling out of the barrel when loading, and,

third, to facilitate the entrance of air from the air-chamber into the barrel back of the shot. I attain these results by the mechanism illustrated in the accompanying drawings, in which- Figure l is a longitudinal section of a wooden barrel and va portion of its breech with my improvements in place. Fig. 2 is a side view of the same, showing the lever and incline for transferring the shot, an aperture for introducing the shot, and slots for working the slides. Fig. 3 shows the manner of operating the lever and counter-slide upon wooden air-guns. Fig. 4; is a barrel and a portion of the air-chambers of a metallic airgun with my appliance attached. Fig. 5 is a side View of the slide which I make use of for forcing the shot toward the breech of the gun. Fig. 6 is an end view of a block that I make use of to attach my appliance to metal air-guns and an end section of a gun-barrel with a bandfor securing the two together. Fig. '7 is a plan of the same, and Fig. 8 is a plan of the counter-slide that carries the shot from the magazine up to and into the barrel of the gun.

Similar letters refer to similar parts th roughout the several views.

A is a gun-barrel.

B is the portion of the breech of the gun that contains the air-chamber.

C is a magazine for storing shot.

D is a spiral spring for forcing the shot toward the breech of the gun.

E is a slide that is acted upon by the spring for forcing the shot toward the breech of the gun.

F is a lever for working a countenslide that throws the shot from the magazine into the gunbarrel.

G is the counter-slide.

His a block or support that I use for attaching my device to metallic guns.

I is a spring for working the lever F.

.I is a hinge used upon wooden-barreled airguns, and K is a charging-rod.

To attach my device to a wooden-barrel airgun, I drill or bore a hole c2 from the breech of the barrel below and parallel with the bore or passage-way d for the magazine C, in which the shot is to be stored. Ithen form a slot c in the side of the magazine and through the barrel for the passage of the handle e of the slide and an enlarged aperture c in the slot to insert the shot: into the magazine. To insure a smooth surface in the magazine, I insert a brass tube Cinto the hole c2, of a proper size to allow the shot to move freely.

For forcing the shot tow-ard the breech of the gun I insert into the magazine a coiled spring D and a slide E, which latter is provided with a handle e, arranged to extend through and work freely in the slot c, for the purpose of drawing the slide back for inserting the shot.

To throw the shot from the magazine to the bore of the gun-barrel, I drill a hole c3 through the back end of the barrel across and at right angles with the end of the magazine and into the passage-way al of the barrel in such a position that a shot may be conducted from the magazine through this opening into the bore oof the barrel. I then make a counter-slide G, having amortise g, for the reception of the end of the lever F, which is intended to work freely in the hole c3. Y

For manipulating the counter-slide G, I make a lever F, which upon wooden guns is attached to the breech in such a position that theproj ection f4 at its back end will rest upon the charging-rod K, and the free end will project forward to engage with the pin P on the counter-slide to throw the slide, the lever being so pivoted that when the barrel is thrown down, as in Fig. 3, for loading, the front end of the lever will be thrown up to position above the pin P, and when the barrel is again brought to place the charging-rod K will press y upon the projection fionthe lever and, turn- IOO ing the lever upon the pivot P', throw the front end down upon the pin and carry the count.er-slide down to the proper position for receiving a shot from the magazine, when the end of the lever, coming in contact with the incline L on the side of the barrel, is carried to one side far enough to allow the pin P to slip by it and the counter-slide to iiy to place. This lever may be made with the back end enough heavier than the free end so that it will drop to position when the charging-rod is thrown down, or it may be provided with a spring i, Fig. 2, and to prevent it from carrying around too far either way I provide a stop P at the base of the incline L, and a similar pin, or stop P2 on the breech of the gun.

In applying the slide G, that throws the shot from the magazine into the barrel, upon wooden guns I bore a hole c3 through one side of the barrel. at right angles with and across the end of the magazine, of a proper size to receive the countenslide, and make a narrow slot or mortise c4 in the side of the barrel for the passage of the pin P on the side of the slide, and to throw the slide up to place I attach the springI to the bottom of the barrel with the free end bearing upon the lower end of the slide. The slide is in this ease provided with an arm or pin P, ol suiicient length to react through, to, and a short distance beyond the surface of the barrel to engage with the lever F for throwing the slide down to position to receive a shot from the magazine, the slide being of a proper length so that when the spring I is in position parallel and hush with the surface of the barrel the upper end of the slide will be just fiush with the lower surface of the bore of the rifle, so as to hold a shot in position and free for the action of the expanding air from the airchamber.

On the outside of the gun-barrel I form a slight incline L, its thickest end being thick enough to carry the end of the lever over the pin Pand allow the counter-slide to be thrown to place.

lith wooden air-guns the barrel is usually pivoted to the breech by means of a hinge J, upon which it is swung down for the purpose of charging the airchamber and cocking the gun or carrying the piston to position for charging the air-chamber.

To prevent the shot from falling outof the back end of the barrel when being thrown to place by the lever and the counter-slide, I diminish the size of the bore back of the slot by inserting a small screw a?, having a sharp point that projects a short distance into the bore of the barrel, or by any other convenient means.

For the purpose of utilizing as much of the elastic force of the air as possible for expelling the shot I make the extreme end of the bore next to the airchan1bcreoncaved or funnel-shaped, as shown in Fig. l, so that the air will not have a square shoulder to meet when entering the bore of the gun.

When applying' my device to a metalhcbarreled air-gun or other air-guns having the barrel rigidly attached to the breech, I find it necessary to change the form of my lever and the manner of attaching it, and for thls purpose I construct a block Il, arranged to t upon the under side of the gun-barrel and provided with a sloth for the reception of the lever, a hole c2 for the reception of the magazine, and a hole c3 for the reception of the counter-slide. I pivot the lever to the block at P and secure all in place upon the barrel by means of metallicbands a af', or by any other suitable device. Vhen using this block and lever, I make a mortise g through my counter-slide for the reception of the lever and dispense with the pin P and .pivot the lever to the front end of theblock in the slot 71, in position so that one cud will pass through the mortise in the slide and the other end will project beyond the end of the block, so that it may be worked by hand, and to hold the lever in position I insert a spring I, of any desired form, in position to act upon the back end of the lever and throw the slide up to position at the surface of t he bore of the gun. The magazine-tube C 1s inserted into the hole c2 in the block, and is provided with a slot for the working of vthe pin e on the slide, and with an aperture for the reception of shot, the same as the magazine in use upon wooden guns.

To use my appliance when attached to airguns, draw the slide E back by means of the pin e until the end passes the aperture c; then drop the shot into the aperture and let the slide be forced against them by the spring D. \Vork the lever I1 (upon wooden guns by means of the charging-rod K with the working of the barrel, and upon guns having rigidly-attached barrels by hand by pressing upon the end of the lever) suiiiciently to carry the counter-slide G from the lower side of the magazine to the bore of the barrel, so that a shot will be carried from the magazine into the barrel at cach stroke of the lever.

IIaving thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with an air-gun having a barrel, a breech, and charging-rods, the barrel being arranged to break down from the breech for charging the air-chamber, of a magazine parallel with the barrel, provided with a slide, a spring, a slot, and an aperture, a counter-slide provided with a pin that projects out through a slot in the side of the barrel, a lever pivoted to the breech in position for one end to act upon the pin P and the other end in the path of charging-lever, and a spring secured to the barrel so as to act upon the counter-slide, substantially as specified.
