SOLID BULLET FOR SHOTGUN-SHELLS.

Speciflcatioh of Letters ratent.

Patented June 3, 1913.

Application filed November 16, 1912. Serial No. 731,755.

To all whom it may concern Be it known that I, JoHN BEOKMANN, a subject of the Emperor of Germany, residing at Oakland, in the county-of Alameda and State of California, have invented new and useful Improvements in Solid Bullets for Shotgun-Shells, of which the following is a specification.

This invention relates to explosives, and particularly to an improved cartridge bullet.

It is desirable in many localities frequented by hunters that their guns, particularly shot-guns, can be utilized both in the hunting of small game and effectually utilized in case of necessity or ordinary hunting when large game abounds, or is likely to be encountered. To that end I have designed and successfully practised shooting with a solid bullet which is readily insertible in ordinary shot-gun shells, either after the usual shot char e has been removed from the same, or which solid shot may be originally placed in the cartridge when the same is made. i

The object of the present invention is to provide a cartridge substantially of the usual shot-gun shell type, and particularly to provide a solid bullet or slug for shotgun shells.

A further object of the invention is to provide a solid bullet for shot'gun shells which may be readily inserted in shot-gun shells, after a charge of shot has been removedj from the cartridge, and which solid bullet isso shaped and proportioned as to protect the shot-gun in which the cartridge @may' be fired against excessive strains due ft'o'thc explosion of the cartridge. The bullet is designed to so fit the barrel of the shot-gun that it will be given a line of flight substantially true with the axis of the barrel, so that its trajectorywill be considerably greater than that of a charge of shot from cartridges with charges. I

The invention consists in combination with a shot cartridge, a solid bullet insertible in the cartridge, and further consists in the particular construction of the bullet.

Figure 1 is a longitudinal section through similar powder v a cartridge loaded with the improved bullet. Fig. 2 is an enlarged view in detail of the bu let. Fig. ,3 is a perspective view of the bullet. Fig. 4 is an end view of the bullet.

In the drawings there is re resented a shell 2 of the shot-gun cartri e type in which is a char e of powder 3. igainst the charge of pow er 3 is placed a series of packlng wads 4. The outer end of the cartridge shell 2 is in this embodiment shown as provided with a solid bullet 5, which bullet may be placed in the cartridge during original process of manufacture, or may be placed in the cartridge after the original charge of shot, which the bullet is designed to supplant, has been removed. After the solid shot 5 has been adjusted in the cartridge the end of the cartridge shell is fasten the follower wad 7 to the bullet 5.

The function of the follower wad 7, attached to the rear of the bullet 5, is to prevent too great an escape of the explosive force around the circumference of the bullet, so that this will be projected from the gun by a large percentage of the explosive force of the cartridge.

In order to protect the thin barrel of the shot-gun in which the cartridge may be used against destructive strains, I preferably form the cylindrical bod portion of the bullet 5 of less diameter than the bore of the gun, so that a portion of the explosive force escaping past the packing follower wad 7 can issue 1n advance of the bullet 5.

In order to give the bullet 5 great carrying capacity and a true line of trajectory from the gun, I form upon the cylindrical surface of the bullet 5 a plurality of longitudinally extending beads or ribs 10, the extreme ridges of which lie in a circumferential line about the cylindrical body of the bullet 5. The circumferential line is somewhat greater than the bore of the shot-gun,

-so that after the cartridge has been placed in the cartridge chamber of the gun and exploded, as the bullet 5 is forced into the bore of the gun the extreme edges of the l0ngitudinal ribs 10 will be forced into frictional engagement with the surface of the bore and thus form a sufiiciently snug fit so that before the bullet issues from the gun it has been given a definite line of flight.-

By reason of the fact that my improved bullet is provided with a substantially solid body portion approximately equal 1n area to the bore of the gun, and by reason of the employment of .the packing follower or wad 7, a. very great portion of the explosiveforce of the powder charge of the cartridge is imparted to the bullet, so that this Wlll carry a much greater. distance than would a charge of shot froma cartridge charge with the same grade and quantity of powder. This type of cartridge can be supplled at substantially the same cost as a shot-charged cartridge and enables the use of a doublebarreled gun, as a rifle and shotgun, by loading one of the barrels with a solid bullet cartridge and the other with a shotloaded cartridge, so that either one. or the other of the cartridges may be used as the exigency requires.

In the event that a hunter has only a single-barreled gun, by carryin with him a supply of shot cartridges and bullet-loaded cartridges he may quickly substltute one for the other in the event of necessity. The hunter can then utilize a single gun for the .use of large and small, game, and in mountainous countries where large and small game exist and abound need carry only a single un and a supply of either or both types 0% cartridges.

The ribs act to guide the bullet straight in line of fire and also form slight, shallow, circumferential passages through which sufficient explosive force can escape to protect the barrel against explosion.

Having thus described my invention, what I claim and desire to secure byLetters Patent is- 1.- A bullet for shot-gun shells, said bullet having a solid cylindrical body portion of less diameter from end to end than the shell to be fitted, circumferentially spaced rojections on the body portion, the inscrib- 1ng circle of which projections is greater than the barrel-bore for guiding and holdin the bullet centrally in the shell, the annu ar chamber about the bullet allowing an escape of gases while the bullet is escaping the gun barrel, and a followerwad immovably attached to the inner or near end of the bullet and of greater diameter than the cylindrical body thereof and approximately fitting the barrel-bore for deriving a maximum safe bullet impulse from the shell charge.

2. A bullet for shot-gun shells, said bullet having a solid cylindrical body portion of less diameter from end to end than the ,shell to be fitted, circumferentially spaced ribs extending the length of the cylinder on the body portion, the inscribing circle ofwhich projections is greater than the barrelbore for guiding and holding the bullet centrally in the shell, the annular chamber about the bullet allowing an escape of gases while the bullet is escaping the gun barrel, and a follower wad immovabl attached to the inner or near end of the bullet and of greater diameter than the cylindrical body thereof and approximately fitting the barrel-bore for deriving a maximum safe bullet, impulse from the shell charge.

3. A bullet for shot-gun shells, said bullet having a solid cylindrical body portion of less diameter from end to end than the shell to be fitted, circumferentially spaced ribs of a length equal, approximately, to the diameter of the cylinder on the body portion, the inscribin circle of which projections is greater than the barrel-bore for guiding and holding the bullet centrally in the shell, the annular chamber about the bullet allowing an escape of gases while the bullet is escaping the gun barrel, and a follower wad immovably attached to the inner or near end of the bullet and of greater diameter than the cylindrical body thereof and approximately fitting the barrel-bore for deriving a maximum safe bullet impulse from the shell charge.

4. A bullet for shot-gun shells, said bullet having a solid cylindrical body portion of less diameter from end to end than the shell to be fitted, circumferentially spaced ribs of a length equal, approximately, to the diameter of the cylinder on the body portion, the inscribing circle of which projections is greater than the barrel-bore for guiding and holding the bullet centrally in the shell, the annular chamber about the bullet allowing an escape of gases while the bullet is escaping the gun barrel, and a fibrous f0llower wad immovabl attached to the inner or rear end of the bullet and of greater diameter than the cylindrical body thereof and approximately fitting the barrel-bore for deriving a maximum safe bullet impulse from the shell charge.

5. A bullet for shot-gun shells,.said bullet having a solid cylindrical body portion of less diameter from end to end than the shell to be fitted, circumferentially spaced projections on the body portion, the inscrib ing circle of which projections is greater than the barrel-bore for guid-inrr and hold- .ing the bullet centrally in the sliell, the annular chamber about the bullet allowing an escape of gases while the bullet is escaping the gun barrel, and a follower wad attached m hand in the presence of two subscribing to the inger or neat?1 end lof the ballet augd 5f wltnesses.
