, Specification of Letters Patent.

Application filed April 8, 1918. Serial No. 227,829.

To all whom it may concern Be it known that I, LEROY A. BERRY, a residing at in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Explosive Shells; and I do declare the following to be a full, clear, and exact description of the inventlon, such as willenable others skilled in.

the art to which it appertains to make and use the same.

y invention hasfor its principal object to provide an explosiveshell which is easily convertible'for use as a from a gun, or as an aerial bomb to be aeroplanes and the like.

he shell body is so constructed as to per- -mit either a projectile head and ,base or an aerial bomb head and base to be attached the arrangement of fuses in said thereto,

- shell body being such as to permit firing cation and in which:

either bythe projectile base or the aerial bomb head. p A still further objectis to provide means for anchoring the shell and rotating it in a vertical osition when dropped from an airship, an projecting a plurality of missiles from the device while so rotating, whereby to establish a danger zone of considerable area.

With the foregoing general objects in Y view, the invention resides in the novel features of construction and unique combinatlons of parts to be'hereinafter fully described and claimed, the descriptive matter being supplemented" y the accompanying drawingswhich forma part of this specifi- Figure 1 is a side elevation of the invention used as an aerial bomb;

,Flg. 4 is a side elevation of the invention used as a projectile; and

Fig; 5 is a longitudinal section of the device shown in Fig. 4.

In the drawing above briefly described, the numeral 1. designates the shell body, 2 and 3'ref'er respectively'to the head and base to be attached to said body 1 in forming'the aerialbomb disclosed in Figs. 1 and 2,, and

The charges 7 are fired in advance of a main cha'rge18 in the bore 4 and in order that the shell body 1 may be broken into a number of pieces when said master charge is exploded, said body is weakened by a plurality. of longitudinal and cir- Patented Apr. 15, 1919'. I

These, splits are-filled with lead or any other suitable material when the shell is manufactured and some similar filler is provided to retain the missiles 6 in the supplemental chambers or be stated thatthemissiles in of incendiary type, of other preferred formation.

Formed longitudinally of the body 1 and opening through both ends thereo are a plurality of longitudinal fuse ports 11 from which branch orts 12 lead to the several Ot or branch ports13' and 14 lead .from the ends ofthe ports 11 into the central chamber 4, the former ing from the rear endsof the ports 11 while the latter (14) extend from the front ends thereof. A plurality of threaded plugs 15 are provided for closin the front ports 14 when the aerial bomb head 2 is employed and for closin the rear ports '13 when-the 2 is used. All of the ports with the exception of those which are filled by the plugs 15, are provided with fuses 16. The fuses of the longitudinal bores 11 are fired by fuses bomb head 2 or by fuses 17 with which the projectile base 3 is equipped, and it will thus be seen that the several charges 7 will be fired before the ignition 'If desired, the head 2 may be provided with a time fuse 18 serving as further ignition means for the may be provided with question may be the shell is dropped, to insure explosion of the device-asfa whole in case the ercussion cap 20 which ignites the fuses 1 and 18, should fail to operate. The fuses 17 terininate at their rear ends in ignition champockets 5. It may hereshrapnel, or of any (13) extend bers21 and a plurality of ports 22 lead to said chambers from'the rear end of'the base 3.

The construction of the projectile head 2 and the projectile base 3' does not vary greatly from similar. parts'now' known, said base being provided with apacking rin 26 for gas, t1 of the gun arrel. This ring 26v connects the two sections of which the base 3 is constructed. The head and'base2 and 3 how-' ever possess wide departures from the 'constructions now followed.
