Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed November 15, 1906. Serial No. 343.526.

To all whom it may concern:

Beit known that f, KAmLVoLLnR, engineer, a subject of th German Emperor, residing at Dusseldorf, I7 .ltilicherstrasse, Germany, have invented certain new and useful Improvements in Explosive Projectiles: and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

' This invention relates to explosive projectiles having two bursting charges, and it has for its object to improve the action of such projectiles when under time fuse fire. For this purpose the grenade charge, in addition to being acted upon by a percussion fuse, is also operated by the time fuse, in a similar manner to the shrapnel charge, but the time fuse communicates with the grenade charge througha retarding device such, that the latter, after the expulsion of the sharpnel charge, will continue its flight for some distance so as only to be exploded in immediate proximity to the mark.

On the accompanying drawing is shown a projectile constructed according to this invention in which Figure 1 shows a vertical section and Fig. 2 an eleva tion. Fig. 3 is a diagram showing the action of the projectile.

The casing a of the projectile contains, as usual, the ball charge which, after the explosion of the powder in the chamber b is propelled forward by the expelling disk c. In front of the ball charge, immediately behind the double fuse, is arranged the bursting charge d, which, as distinguished from previous construct-ions, entirely fills the front chamber. In this chamber is also provided the smoke producer 2.

The balls which, in previous constructions, were arranged round the grenade charge are omitted in this construction, as they are pressed flat by the explosion, so that the grenade charge is entirely outside the shrapncl charge. For increasing the grenade action the front walls are made specially thick.

The detonator f is arranged so that on the one hand it can be fired by the percussion fuse by the igniting pellet 9 and on the other hand it can also be fired by the powder pellet h.

The time fuse may be of any well known type. In that shown the primer 1 is exploded by being thrown against the anvil m by the set back upon firing, where: upon the flame passes by way of the double time'ring n and the channels t' and k to the explosive b, and also from the channeli by way of the slow burning pellet h to the detonator f. The percussion fuse is also of the ordinary type, the. primer pellet 9 being thrown forward against the anvil o by its inertia upon the sudden stopping of the projectile, and the flame passing through the uncovered channel p to the detonator f.

I s I l l l l l l l l l l l l l l l l l l l j l r l present improved con When using the projectile with time fuse fire, the charge in the base chamber is ignited by the time fuse through the channel i and tube It, and at the same time the powder pellet h is also ignited. The expcllingdisk c then throws forward the head of the shell with the grenade charge, the percussion fuse and the burning pellet h, after which follows the ball charge. The duration of the burning pellet h is so adjusted that the grenade charge will be detonated in the immediate vicinity of the mark. In the event, however, of the grenade part previously striking an obstacle, the per cussion fuse comes into action.

The advantages of this construction as compared with those heretofore employed, in which the grenade charge was exploded simultaneously with the shrapnel charge or directly after the expulsion of the balls, will'be s n from Fig. 3, where S is the point of explosion of the shrapnel. The ball charge is thrown forward from this point with conical dispersion, and in the known construction the grenade charge would be detonated either at the same time or immediately afterwards, and the burst fragments would be dispersed still at a considerable distance from the mark fired at, as indicated by the lateral dotted lines. With the struction however the head of the shell with the grenade charge will continue its flight for some distance in front of the balls and will only be detonated at the point T directly over the object fired at. It will be evident from the above that the destructive action of the projectile upon the object fired at will be considerably increased.

As compared with the projectiles in which the grenade part continues its flight until it is detonated by the percussion fuse in coming in contact with an object, the new construction affords the advantage that the dispersive action is increased by the fact that the point of explosion occurs inthe air. In addition, misfircs which may occur through unfavorable impact of the percussion fuse are entirely obviated. A further advantage is obtained in that when firing under conditions in which the projectile must be exploded at a short distance from the gun, a rearward action of the grenade fragments upon the gun cannot occur as the grenade charge continues to fly forward some distance until, in the vicinity of the mark, it is exploded in the air, so as to produce its full effect. i

The described construction of the projectile allows of a particularly favorable utilization of the weight thereof, so that both the ball charge and the grenade charge can be increased.

The invention can of course also be applied in a corresponding manner to projectiles which have the grenade charge in the rear in place of in front. as described.

Having now particularly described and ascertained the nature of my said invention and in whatv manner the same is to he performed, I declare that what I claim is:
