INVENTUR.
UNITED STATES PATENT EEIOE.
iMPRovEMEN-r IN PROJECT-ILES.
Specification forming part uof Letters Patent No. 119,313, dated September 26, 1871.
To all whom it may concern:
Be it known that I, JOHN G. BUTLER, United States army, of Fortress Monroe, in the county of Elizabeth City and State of Virginia, have invented an Improved Projectile for Billed Guns, of which the following is a specification:
My invention relates to improvement in projectiles for rilled ordnance; and it consists in applyingto the same, by any suitable inode ofV attachment, a continuous circular-band having a deep posterior slit. Hitherto, cups or saucershaped devices have been attached to the rear ends of projectiles, for thepurpose of centen ing the projectiles by expansion into the grooves of the gun in consequence of the action ofthe powder-gas. They have, however, been so applied as to lengthen the projectiles, a defect my invention is designed to obviate.
In the drawing, Figure 1 is a side elevation, partly in section, of an annular or continuous band applied to the rear end or base of a pro jectile, and'Fig. 2 is an end view of the same. Fig. 3 shows a similar band connected with a projectile.
A indicates the body of the projectile, and B the split annular band shown, applied thereto, in two diferent ways as per Figs. l and 2. A male screw-thread is out in the projectile and a corresponding female screw-thread on the inner surface of the annular band. Metallic keys K, are inserted in holes drilled in theend ofthe projectile for thepurpose of preventin gthe band from turning or slipping. In Fig. 3 the band is shown attached by being cast upon the projectile, in
which D D and G are offsets from the shoulders F F, the same forming aseries of connected cells or one continuous groove, varying in depth, around the projectile, for the purpose of receiving the molten metal, (forming the band). O is the upper and P the lower lip of the annular band. E is ,the opening between the lips designed to receive the powdergas, whose instantaneous entrance is facilitated bythe tapering or Wedge-shaped form of the opening, and the posterior projection of the upper-lip O. S T indicate the rounded or beveied junction of the band and the projectile. By thus slitting or grooving the band I provide a long expandinglip, and at the same time avoid the necessity of allowing the projection lof the same to any considerable eX- tent beyond the end of the projectile; this renders projectiles to which they are applied capa-y ble of being packed in smaller space, reduces the cost, and facilitates handling.
Having thus described my invention, what I claim las new, and desire to secure by Letters Patent, is-
l. The split or slitted annular band B applied to the base of a projectile, substantially as specied.
2. The double-lipped band B attached to the projectile by means of p the screw-threads and metallic keys K, substantially as specified.
, JOHN G. BUTLER.
