HEINRICH BRUS'I, OF CASSEL, GERMANY.

PROJECTILE.

Specification of Letters Patent.

Patented July 26,1910.

Application filed September 25, 1909. Serial No. 519,615.

To all whom it may concern Be it known that I, HEINRICH BRUST, a subject of the Emperor of Germany, resid .mg at Cassel, Germany, have invented cer- 'ive have not so far been successful.

The present invention relates to a projectile which will meet the requirements in that it involves the advantages of both shrapnels and common shells. -The improved projectile is composed of a casing which is fitted on the outside with fin-like worms, adapted to rotate the projectile, during flight, round its longitudinal axis, and

which is provided in its lower portion with a shrapnel charge and in its upper portion with a set of filllng projectiles charged with a powerful explosive. o

In the accompanying drawings the invention is illustrated, Fi ure 1 representing a central section through the charged projectile, Fig. 2, a central section through the empty casing, Fig. 3, a section of one of the filling projectiles, Fig. 4, a side view of the projectile showing its exterior worms, Fig.

5, a section of a filling projectile of another form of construction, 6, a sectional elevation of a projectile, showing a different way of loading the same, and Fig. 7, a section along line AB of Fig. 6.

A casing 01', with cylindrical bore, has a bottom chamber 6- adapted to receive the bursting charge for the shrapnel. The driving plate 0, which is slightly arched, rests 'on a shoulder formed in the jacket and has a central aperture for the reception of the ignition tube. The latter is divided. into two parts d and e which arese-parated by a pellet f of some slowly burning powder. The sharpnel charge 9 rests on the driving plate 0 and is covered by a disk h which is held by another shoulder in the jacket a. Above the disk It a propelling-charge is provided, the object of which is to d} We Oht,

by means of a driving plate is, the filling projectiles Z arranged on the latter. The projectile is closed by a suitable'fuse capsule m which is held in the casing a by a weak screw-thread allowing it to-disappear from the casing immediately the ignition takes place, so as to leave, the passage clear for the filling projectiles. v

To facilitate the loading of the casing,'it is preferably composed of two' parts screwed together, as shown in Fig. 2.

The casing a is fitted on t in any the air he outside Withfin-like worms n, fixed to the casin sultable manner. The resistance 0 on said worms, during the flight of the projectile, effects a rotation of the latter round its longitudinal axis.

l/Vhen the projectile is loaded in the gun, the spaces between the worms are filled with some fusible material, such as sulphur, resin, or the like, so asto give the projectile a firm bearing in the gun.

The elongated filling projectiles -Z consist of a shell provided on the nose with a percussion fuse 0 and at the base with a fuse"p. The interior 9 ofv the shell is filled with an explosive of the most powerful nature, capable, when ignited by the percussion fuse o through the projectile striking. against any hard object, for instance a protective armor,

of breaking such object into fragments. If not previously hitting any. object, the pro j ectile will, after a lapse of 2/ 10 second from the time ofignition of the charge 71, 2'. 6., at a speed of 250 meters, after'a flight of. another 50 meters, be exploded by means of the fuse p which is ignited through the heat developed by the ignition of the charge The'fiash which ignites the charge 71 also ignites the. pellet f which, after a lapse of 1/10 second, transmits the flash to the bottom chamber 6 which then effects a shattering of the shrapnel charge g. Through this interval-between the explosions of the different charges, the pro ectiles l will have time to make way for the bullets of; the. shrapnel charge. The advantage of the 1m-, proved projectile is, therefore, that it is capable, first of shatterin the protections of a battery and then of charge against the occupants. v V

The chance of hitting the battery is increased by the number of filling projectiles employed. p

When the elongated filhng projectiles can not be made to act satisfactorily, the may irecting' the bullet be substituted by spherical-,proj ecti es, as

s an through the projectile striking against a hard object, for. instance an armor.

Figs. '6 and 7 show a different mode of loading the projectile. The elongated filling projectiles are here arranged in metal tubes 1), out of which they are thrown by the propelling charges 2'. These tubes serve to direct the projectiles Z and revent them from turning over-during the ight.

1. A"projectile,-comprising in combination, a casing fitted on the outside with finlike'worms adapted to rotate the'projectile during its flight, an ignition tube in the center of said casing, a shrapnelcharge in the lower'portion of said jacket, a set of filling projectiles in the upper portion thereof, a propelling charge for driving out said filling projectiles, and a pellet of slowly burning powder in said ignition tube adapt-. ed to delay theignition of the shrapnel charge till the filling projectiles have been driven out, substantially as and for the purpose set forth.

2. A projectile, comprising in combination, a casing fitted on the outside with finlike worms, a fusible material provided in the spaces between said worms, a bottom chamber adapted to receive a burstin charge, a driving plate arranged over said chamber and resting on a shoulder in the casing, an ignition tube projecting through the center of said plate, shrapnel bullets arranged round the lower part of said tube,

' j a disk covering said bullets and held by a shoulder in the casing, a propelling charge disposed on said disk, a driving plate cover.-

ing sa-id propellin charge, projectiles, char e with po driven out of charge, and a pel s y said propellin ie of slowly burning powd tween the bursting charges, to delay the ignition of. the bottom charge until the er in said ignition tube bet? filling rojectiles have been driven out, subst-antia lyas set forth.

A projectile, comprising in combine: tion, a casing having in its lower portion a shrapnel chargeand in its upper portion a set offilling projectiles charged with DOV/GI- ful explosive, a propelling charge auapted to drive out said projectiles, a bursthig charge adapted to disperse the shrapnel. hullets, an charges, and a pellet of slowly burning powder arran "ed in said tube between the charges an adapted to efiect an ignition ,of the bottom charge after the ignition of the upper one, substantially as and for the purpose set forth. a

4. A projectile, com rising in combination, a casing having n-like worms on its exterior adapted to rotate the projectile during its flight, a shrapnel charge in the lower portion of saidcasing, filling projectiles in the upper portion of the same, a propelling charge adapted to drive out said projectiles,
