REPEATING AIR-RIFLE.

SPECIFICATION forming part of Letters Patent No. 662,054, dated November 20, 1900.

Application filed January 4, 1900. Serial No. 299. (ModeL) To all whom it nzay concern:

Be it known that 1', WILLIAM J. BURROW, a citizen of the United States, residing at Plymouth, in the county of Wayne, State of Michigan, have invented certain new and useful Improvements in Repeating Air Rifles; and I do 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 use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to a repeating spring air-gun; and it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claims. J

The object of the invention is to provide for an air-gun of the class described a magazine feed or repeater mechanism in which the arrangement is such as to conveniently retain the slot in a magazine formed between the false barrel and the true barrel of the gun to enable the shot or projectiles to be fed one at a time into the true barrel of the gun in a simple and efficient manner and to enable the operator to see that a shot or projectile has been fed into the true barrel upon each operation of the feeding device.

The above object is attained by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a general view of a gun embodying my invention. Fig. 2 is an enlarged elevation of the muzzle end of the barrel, showing the screw, by means of which the feeding-disk is actuated, projecting through a slot in the false barrel of the gun. Fig. 3 is a longitudinal section through the true barrel and the false barrel as well as the feeding mechanism located between said barrels. Fig. 4 is a longitudinal sectional view through the forward end of the false barrel, showing the true barrel therein and the shot-feedingtion, as on line 6 G of Fig. 4. Fig. 7 isa like section, as on line 7 7 of Fig. 4. Fig. Sis an elevation of the muzzle of the gun. Fig. 9 is a detail in longitudinal section through the barrel of the gun and feeding mechanism, as on line 9 9 of Fig. 5.

Referring to the characters of reference, 1 designates the stockof the gun, to which the false barrel? is hinged in the ordinary manner of a breakdown-gun, said false barrel containing an air-chamber, in which a springpropelled piston (not shown) is adapted to reciprocate in a manner well understood in the art. Communicating with the air-chamber 3 (see Fig. 5) is the true barrel 4, having a contracted seat 5 at its breech to arrest and hold the shot or projectile in position for firing when placed in said barrel. The false barrel is of greater diameter than the true barrel,

which is supported centrally withinthe false barrel. The end of the false barrel is closed by a circular plate 6 in the muzzle thereof, through the center of which the true barrel 4 extends.

Mounted upon and made fast to the exterior of the true barrel is a spiral column 7 of such diameter as to fill the interior of the false barrel. The spiral formation of said collar serves to direct the shot to the base thereof. At the base of the incline plane 8 of said spiral collar is an opening 9, formed through said collar of such diameter as to freely receive the shot. By locating the collar 7 within the false barrel, so as to surround the true barrel, a magazine 10 is formed, surrounding the true barrel between the collar 7 and the muzzle-plate 6, adapted to contain the shot or projectiles 'to be fired from the gun, the shot being placed in the magazinechamber through the aperture 11, formed in the plate 6 and communicating with the magazine 10. The shot may be confined within the magazine by a suitable plate (not shown) to close the aperture 11.

Secured upon the exterior of the true barrel below the spiral collar7 and spaced therefrom is a fixed collar 12, having thereon the radial lugs 13. Mounted upon the exterior of the false barrel, between the collars 7 and 12, is a rotary disk 14, through the center of which said barrel passes and forms the axis of oscillation of said disk. In the upper face of the rotary disk 14 is a ehannel15, extending diametrically of said disk and adapted to normally register with the aperture 9 in the collar 7. Formed through the wall of the true barrel 4 is an aperture 16, through which a shot is adapted to pass from the channel 15 in the disk 14L when said disk is rotated, so as to bring the inner end of said channel into alinement with said opening 16 into the true barrel, as shown by dotted lines in Fig. 6. The shot upon entering the true barrel from the channel in said rotary disk drops to the seat 5 at the breech of said barrel in position for firing, as will be well understood. The rotary disk 14 is actuated by means of a screw or pin 17, which enters the edge of said disk and projects through a slot 18 in the wall of the false barrel, which allows of the travel of said screw as the disk is oscillated. The slot 18 is extended such distance around the barrel as to expose a portion of the channel 15 in the disk 14, as clearly shown in Fig. 2, whereby the operator can determine beyond a question whether or not a shot by the operation of said disk is discharged from the magazine into the true barrel of the gun.

To maintain the rotary disk 14 normallyin position to cause the channel 15 therein to register with the aperture :4 in the spiral collar 7, a spring 19is secured at one end to the barrel of the gun and at the other end is caused to engage the rotarydisk 14, as clearly shown in Fig. 9, whereby said disk is normally held with its channel 15 directly in line with the aperture 9 in the collar 7, so that a shot when the parts are in their normal position will pass from the magazine through said aperture in said collar and lie in said channel in position to be discharged into the true barrel of the gun by a rotation of said disk sufficient to cause said channel to register with the opening 16 in said barrel and allow the shot to roll from the channel into the barrel through said opening 16 and fall to the seat 5' at the breech of said barrel. Upon releasing the actuating-screw 17 of the disk 14: the tension of the spring 19 will return said disk to its normal position, when another shot will drop into the channel thereof through the aperture 9 into the collar 7, whereby it will be seen that through the operation of said disk the shot may be fed one at a time from the magazine into the barrel of the gun, the parts after each operation restoring themselves for a succeeding operation. To limit the movement of the disk 14, a ing 20 is formed on the rear face thereof, which lies between the lugs 13 on the collar 12 and which is adapted to engage said lugs to arrest said disk in its movementin both directions. By

providing the collar 7 with a spirally-inclined face 8 the shot are thereby directed to the aperture 9 in the collar at the base of said incline, so that the last shot in the magazine may be properly discharged therefrom.

Having thus fully set forth my invention,

what- I claim as new, and desire to secure by Letters Patent, is-

1. In a repeating air-rifle, the combination of the true barrel, a magazine, a channel leading from the magazine into said true barrel, a movable disk having a portion of the channel formed therein, said channel in said disk being normally closed from communication with the true barrel.

2. In a repeating air-rifle, the combination of the true barrel, a false barrel forming a magazine-chamber, amovable disk having a channel therein, an opening in the bottom of the magazine normally communicating with the channel in said disk, the true barrel having an opening therethrough normally closed by said disk, the channel in said disk being adapted to register with the aperture in said barrel by a movement of said disk.

3 In a repeating air-rifle, the combination of the true barrel, a shot--magazine adjacent thereto, the bottom of said magazine having an opening for the passage of the shot therefrom, the true barrel having an opening in the Wall thereof for the passage of the shot into said barrel said barrel-opening being out of alinement with the opening in the bottom of the magazine, a movable member having a shot-conveying channel therein adapted to be moved to cause said channel to alternately register with the opening in the bottom of the magazine and the opening in the wall of the true barrel.

4. In a repeating air-rifle, the combination of the false barrel, the true barrel therein and spaced therefrom, a magazine-chamber within the false barrel surrounding the true barrel, said magazine-chamber having an inclined bottom, provided with an aperture at the base of said incline, the true barrel having an aperture through the wall thereof, a movable part mounted on the true barrel and adapted to close the aperture therethrough, said movable part having a shot-receiving channel in its upper face which normally registers with the aperture in the bottom of the magazine, said channel in said part being adapted to register with the aperture in the barrel by a movement of said part and a spring engaging said movable part.

5. In a repeatingair-rifle, the combination of the false and the true barrels, the magazine within the false barre], a shot-conveying channel leading from the magazine into the true barrel, a movable part having a portion of said channel formed therein, a slot in the wall of the false barrel through which a portion of the channel in said movable part is visible and means for moving said movable part.

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