tic dishing of the armor plate fied at. The
function of the plug 21 i to provide an
opening for the introduction of water, if
;r'qured, to wet down the gun ctton or
& -xplasive mass 13.
- Connected with the base 14 is a centrifu-
gal fuse 24 of any well known or preferred
type. The numeral 25 designates a detona-
tor attached to the centrifugal fuse and
10 preferably formed of dry gun cotton.
In Figs. 7 and 8, I have dispensed with
the jacket 18 and have substituted therefor
panels 26, which are preferably formed of
mild steel. These panels are of course
15 curved in cross-section, to conform to the
curvature of the legs. The panels 26 may
he held in place by any suitable means. It
is thus seen that the panels 26 together with
the legs 11 form a large chamber for receiv-
20 ing the explosive mass. When the explo-
sive mass or charge is of powder or the
like and is fed into the chamber formed by
the panels 26 and legs 11 by removing- the
base 14, said panels 26 may be connected
25 with reinforcing spiders 27. 1 may also
dispense with these spiders and cast the
panels 26 integral with the legs 11.
The operation of the projectile is as fol-
lows:-The projectile is shot from a gun
30 properly aimed at the object to be hit.. The*
wind shield or cap 19 causes the projectile
to have accuracy in flight. When the pro-
jectile strikes the armor plate or the like,
the head 10 penetrates the same and the ex-
35 plosive mass 13 explodes soon afterward.
The reinforcing legs 11 strengthen the inner
frame or body portion of the projectile and
also provide a very large chamber or recess
for holding the maximum amount of ex-
40 blosive charge, whereby the explosion which
occurs after the penetration of the armor
plate will be very disastrous.
I wish it understood that I do not restrict
myself to the employment of gun cotton as
45 an explosive agent alone, as any well known
or preferred type of explosive agent may be
employed. It is ordinarily preferable, how-
ever, to employ an explosive agent which
may be molded into a suitable form, to be
50 slipped into the space or opening formed
within the legs 11.
It is to be understood' that I do not re-
strict myself to the forms of my invention
herewith set forth, but that certain changes.
55 in the shapes, sizes, and arrangements of
parts may be resorted .to without departing
from the spirit of the invent ion or the scope
of the subjoined claims.
Having thus described my invention, I
60 claim:- -
1. In- a -projectile of the character de-
scribed, an inner frame including a pene-
trating head carrying trailing spaced legs
for providing a very large. chamber, an ex-
65 plosive charge disposed within the chamber,and means to explode said explosive charge
after the impact of the penetrating head
with the. armor plate or other object
aimed at.
2. In a projectile of the character de- 70
scribed, an inner frame including a pene-
trating head carrying a suitable number of
spaced trailing legs to provide a very large
chamber within and between the same, a
mass of explosive material disposed within 75
said chamber, means disposed adjacent the
spaced legs to prevent the explosive mate-
rial from passing between the same out of
its chamber, and means to explode said mass
of explosive material after the impact of 80
the penetrating head with the armor plate
or other object aimed at.
3. In a projectile of the character de-
scribed, an inner frame comprising a pene-
trating head carrying spaced trailing legs 85
suitably stiffened by reinforcing ribs, a.
jacket surrounding the spaced. legs to form
therewith a. large chamber, a mass of ex-
plosive material disposed within said large
chamber, and.means to explode said mass of 90
explosive material after the penetrating
head impacts with. the armor plate or other
object aimed at.
4. In a projectile of the character de-
scribed, an inner frame comprising a pene- 95
trating head carrying spaced trailing legs
suitably stiffened by reinforcing ribs, a
jacket surrounding the spaced legs to form
therewith a large chamber, a mass of ex-
plosive material disposed within said large 100
chamber, means to explode said mass of ex-
plosive material after the penetrating head
impacts with the armor plate or other ob-
ject aimed at, and a suitably tapered cap
surrounding the penetrating head and con- iob
nected' therewith to insure accuracy in flight
of the projectile.
5. In a projectile of the character de-
scribed, an inner frame comprising a pene-
trating head carrying' spaced trailing legs 110
providing therebetween a large chamber, a .
suitably molded mass 'of explosive material
adapted for insertion within, the chamber
through the open end of the same, a base
connected with said legs to close said open 11r
end of the chamber, a suitably long tapered
cap surrounding the penetrating head and
connected. therewith -to insure accurate
flight of the projectile, and means to ex-
plode said explosive material after the im- 120
pact of the penetrating head with, the armor
plate or other object aimed at.
6. In a projectile of the character. de-
scribed, an inner frame comprising a suit-
ably tapered penetrating head carrying 125
spaced substantially diametrically arranged
longitudinal trailing legs reinforced with
longitudinal ribs and providing a large
chamber having one end thereof normally
open, a jacket surrounding the legs, a mass 1S
