The invention described herein may be manu
factured and used by or for the Government for
governmental purposes, without the payment to
me of any royalty thereon.
This invention relates to aerial bombs, more
particularly, of the type provided with a time
fuze set to explode the Ibomb at a predetermined
height above ground and cause the scattering of
the bomb fragmentations over a considerable
target area. The object of the invention is to
provide a bomb of the character indicated which
in exploding will cause the shrapnel to burst
downwardly instead of laterally or outwardly, so
that the shrapnel is sprayed in an umbrella pat
tern. For the attainment of this and such other
objects of invention as may appear 0r be pointed
out herein I have shown an embodiment of my
invention in the accompanying drawing, wherein:
Figure 1 is a sectional elevation through the
improved bomb of this invention;
Figure 2 is a Cross-section taken on the line
2--2 of Fig. 1;
` ,
Figure 3 is an isometric view of an anvil com
ponent; and
Figure 4 is an isometric View of a ring com
ponent.
The improved aerial bomb of this invention
comprises a forward nose member l and a rear

inner tube I5 are a plurality of pieces which I
have termed “anvils” and which are designated
generally as 2l). Anvils 2i), which may be cold
rolled steel stampings or steel or iron castings,
are annular or ring~shaped as best shown in the
detail thereof in Fig. 3, defining a central hole
25 somewhat larger in diameter than inner tube
l5 so that the anvils may be slipped over the
inner tube. The top and bottom surface of the
anvil are inclined downwardly, with the inclined
top surface 2i parallel to the inclined bottom sur
face 22, Fig. 3, so that the anvils may be stacked
one above the other as shown in Fig. 1. Cut in
the bottom inclined surface 22 of the anvil are a
plurality of radial channels 26 spaced at equal
distances from each other around the circumfer
ence of the anvil.
Channels 26 are also down
wardly inclined and parallel to top and bottom
inclined surfaces 2i and 22 of the anvil.
A lock
20 ring i8, Fig. 1, may be placed above the top anvil
2l) and fitted tightly around the inner tube l5 to
hold the stack of anvils in place.
Surrounding the stack of anvils is the outer
tube 5. Encircling outer tube 5 and also stacked
like the anvils 20, are a plurality of pieces which
I have termed “rings” and which are designated
generally as 30 and which, as best shown in the
detail thereof in Fig, `4, are annular or ring

best seen in Fig. 2.
