IFiled Dec. 31, 1942 Patented Dec. 28, 1943 UNlTED STATES TEN OFFICE BOMB John Nahirney, Detroit, Mich. Application December 31, 1942, Serial No. 470,717

1 Claim.

This invention relates to improvement in bombs. It is an object of the invention to provide a bomb including an outer cylindrical shell having one closed conical extremity to the bore of which one end of a cylindrical inner casing is secured, thereby forming an annular space between the shell and the inner casing to receive a large number of projectiles while an explosive charge is housed within the casing.

Another object of the invention is to provide such a bomb wherein one end of the inner casing is secured to the bore of the shell and is closed by the conical extremity of the latter, and a cap closes the opposite end of the casing and is provided with an annular projection which retains a flange in position over the adjacent end of the shell to close the annular space wherein the projectiles are loaded. Moreover the cap and flange arrangement is such that the latter holds the inner casing concentric in the shell and thus reinforces the attachment of the other extremity of the inner case to the conical end of the shell.

A further object of the invention is to provide a bomb which is cheap and simple to manufacture, and easy to load and charge.

Having thus stated some of the objects of the invention I will now proceed to describe the invention in detail with the aid of the accompanying drawing, in which the figure illustrates a longitudinal section of the invention.

Referring to the drawing, I designates a cylindrical inner casing which is filled with an explosive charge I0, and 2 is an outer cylindrical shell having a closed conical extremity to the bore of which one extremity of the said inner casing I is suitably secured as by welding or in any other preferred manner. To insure a better contact between the bore of the shell and the end of the inner casing the latter may be inwardly tapered to correspond with the inclination of the conical end of the bore of the shell which is substantially parallel to the outer periphery. Extending, preferably axially, through the closed conical extremity 3 of the outer shell 2 is a spindle 4 on a conventional fuse device 5 which is provided within the adjacent end of the inner casing I to detonate the charge I0. Loaded in the annular space confined between the inner casing I and the outer shell 2 are projectiles which in the present instance are shown partly as slugs or pellets l I of irregular shape and partly as fiat pieces of metal Ila. lying one on top of the other, though obviously either the slugs or the flat pieces of metal may be used to the exclusion of the other if preferred.

The opposite extremity of the shell 2 is closed by an annular flange 6 having a downturned outer margin which fits over the outer periphery of the said shell. The adjacent end of the inner casing I is internally threaded to receive a cap I which has an annular projection Ia that extends over the inner portion of the flange 6 and retains it in position and also helps to maintain the casing and shell concentric or coaxial since the bore of the flange 6 lies immediately adjacent the outer periphery of the inner casing. 3 denotes a countersunk multi-sided wrench receiving opening in the outer side of the cap I for screwing the latter into the casing, and 9 are wings for retaining the bomb substantially in vertical alignment during its fall.

While in the foregoing the preferred embodiment of the invention has been described and shown, it is understood that alterations and modifications may be made therein provided the said alterations and modifications fall within the scope of the appended claim.

What I claim is:

A bomb including a cylindrical inner casing having an explosive charge therein, a cylindrical shell coaxial therewith spaced around the casing, said shell terminating at one extremity in a substantially conical closed end through which a fuse mechanism projects, the bore of the shell extending into said conical closed end and the thickness of the shell being uniform throughout its length, one end of the inner casing being annularly secured to the bore of the shell toward its conical end whereby a projectile space is defined between the casing and shell, an annular flange on the opposite end of the. shell having a downturned margin extending around the periphery of the latter, the bore of the flange terminating immediately adjacent said casing, the free end of the casing being internally threaded, a cap in threaded engagement therewith, and a projection on said cap retaining said flange in position.
