AERIAL BOMB.

To all whom it may concern: I

Be it known that I, BOYD A. SIGLER, a citizen of the United States, residing at Sioux Falls, in the county of Minnehaha and State of South Dakota, have-invented certain new and useful Improvements in Aerial Bombs, of which the following is a specification.

My invention relates to improvements in aerial bombs.

An important object of the invention is to 'provide a bomb of the above mentioned character having means whereby a plurality of relatively small projectiles are first thrown from the body of the bomb, upon the same striking the ground or target, and sub-- sequent towhich the body of the bomb is exploded, and thrown in divers directions.

A further object of theinvention .is. to provide a. bomb of the above mentioned character, having the projectile receiving openings arranged in the wall thereof, in

such a way that the wall is rendered breakable into sections, which are projected in divers directions.

A further object of the invention is to provide a bomb of the above mentioned character which is automatic in operation. Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a central vertical longitudinal sectional view through a bomb embodying my invention,

- tinuation of theshell 10.

' The shell 10 is provided with radially extending openings 14, which pass through the inner and outer sides of the wall thereof. The openings 14 are arranged in longitudinal and horizontal circumferential groups, providing relativelylarge portions or squares 14 which are readily breakable from each other, by virtue of these openings, as will be more fully explained. These openings are adapted for thereception of relatively small projectiles or bullets 15. Instead of employing a single bullet 15, I may employ a wrapper 16, filled with shot or small projectiles 17, as shown.

The shell 15 is filled with a propelling charge 18, and this charge, upon exploding,

forces the projectiles 15 through and from the openings 14.

The nose 13 is provided with an interior recess, filled by a plug 19. This plug has a chamber 20, and passages 21, formed therein. The passages 21 lead to the projecting charge 18, as shown.

Arranged centrally and longitudinally within the shell 10 is an exploding member 22, filled with an exploding charge 23. The member 22 is inserted within a thin metallic casing 24, held in place by stationary lugs 25, secured to the shell 10. The member 22 is capable of moving forwardly longitudinally within the casing 25, and this movement is normally opposed and prevented by a compressible coil spring 26. A combined cap and fuse 27 is secured to the plug 19 and.

leads to the chamber 20, while a longer combined cap and fuse 28 is secured to the lower end of the member 22 and leads to the interior thereof.

When the projectile is dropped from a flying machine or the like, the same descends by gravity and upon contacting with the ground or target, the member 22 moves forwardly with relation to the shell 10. This movement brings the combined cap and fuse $28 into contact with the combined cap and fuse 26, whereby they are both ignited. The

sequent to this operation, the exploding.

charge 23 is ignited, and the entire bomb including the shell 25, is blown to pieces. The openings 14 by'being arranged inthe precise manner, as illustrated in Fig. 6, form relatively. large portions or squares 14', which are readily breakable from each other, and

these portions or squares are projected in divers directions. a

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that variouschanges in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, I claim i 1 1. An aerial bomb of the character described, comprising an outer shell having a plurality of transverse projectile openings,

projectiles for insertion in the openings, a

cap secured to the forward end of the outer .shell and having an interior recess, a plug arranged within the interior recess and having a main inner chamber and ports extending outwardly therefrom and leading into the interior of the outer shell, an inner tube extending longitudinally of the outer shell, a firing charge arranged Within the space between the outer shell and inner tube and leading-to the ports, a casing mounted rei ciprocate within the inner tube, an exploding charge arranged within the casing, a combined cap and'fuse anchored withinthe inwardly beyond the casing, said second named combined cap and; fuse being substantially longer than the first named combined cap and fuseand adapted to contact with the first named combined cap and fuse, and

yielding means to; oppose the forward movement of the casing.

2., A device :of the character described,

comprising an outer casing having a plurality of transverse openings, projectlles for insertion within the openings, an inner tube extending longitudinally within the outer casing, an exploding charge arranged within the outer casing exteriorly of the inner tube, an inner casing arranged within the longitudinal tube and adapted to move forwardly-therein, means to'oppose the forward movement of the inner casing, an exploding charge within the inner casing, and'means operated by the forward movement of the inner casing to, fire the first named exploding charge and subsequently fire the second named exploding charge.

In testimony whereofI aflix my signature.

BOYD A. SIGLER.
