Application filed May 2, 1904.

T all whom it may concern:

Be it known that LWILHELM ULRICH, a subject of the Emperor of Germany, and a resident of Essen-on-tl1e-Ruhr, Germany, have invented certain new and useful Improvements in Cartridges, of which the following is a specification.

The present invention relates to those cartridges or cartouches in which a so-called auxiliary or priming charge is arranged between the percussion-cap and the main driving charge, which has the effect of reinforcing the the coming from the percussion-cap, and thereby insuring a safer ignition of the driv ing charge. In cartridges or cartouches of this type the auxiliary or priming charge has usually been arranged in a bag and this bag placed between the driving charge and the base of the shell in immediate contact with the latter. In such arrangements there is great danger of the auxiliary-charge, bag becoming penetrated in transportation of the cartridge or cartouche in consequence of the pressure of the driving charge resting upon it, as well as the pressure of its own mass, followed by the scattering and dissipating ofthe auxiliary charge and its failure to perform its function.

The present invention has for itsobject to avoid this possibility, and this object is at tained by securing the auxiliary charge to the dome of a hollow chamber which is -provided between the base of the cartridge and the driving charge, the arrangement as Well as the dimensions of the hollow chamber and auxiliary charge being so selected that notwithstanding any vibrations of the parts the auxiliary charge cannot come in contact with the percussioncap chamber or with the base of the shell.

In the accompanying drawings, forming part of this specification, three embodiments of the invention, by way of example, are illustrated by portions of three cartridges shown in vertical longitudinal section.

Referring first to the embodiment trated in Figure l, a bell-shaped part C rests upon the base B of the cartridge-shell, which \bell-shaped part may be constructed of brass, pasteboard, pressboard, smokeless powder.

or the like. The dome (no part ports the driving charge llevahiohimay' e, for

example, tubular powder-'1 Nfithinfitherpart stood that the described arrangement will absolutelyprevent the penetration of the auxiliary bag and the scattering and dissipating of the auxiliary charge in a safe manner.

According to the embodiment of the invention illustrated in Fig. 2 the auxiliary charge E is carried by an inserted part C, as in Fig. 1; but a bowl-shaped depression 0 in the dome of the inserted part serves as a container for the auxiliary charge E, so that a special bag for this charge is not necessary. The container c is closed in the direction of the driving charge D by a cover 0, pasted or otherwise secured in position. In the bottom of a the depression 0 as also in the cover 0*, bores may be provided for the passage of ,the fire, and these bores may be closed against the escape of the, auxiliary charge by pieces of gauze or the like.

- According to the embodiment shown in Fig. 3 the walls of the bell-shaped hollow chamber are formed by the driving charge D itself. For this purpose the inner tubes (2 of a suitably-bound bundle are made shorter to a certain extent than the outer tubes d at the end of the bundle presented toward the base of the cartridge-shell, and this relative position of the tubes issecured by suitable mearis for example, strongly tying the bundle. The bag F, containing the auxiliary charge E, is then attached immediately to the inner tubes (11. It is obvious that without departing ing any vibration which occurs with the dome C is a bag F, containing th'e'adxiliary charge E, secured to the domadcin a y desired mannerr'or example, by pasting-,-fs winglnscg'55 5 From the drawings it will be clearly under from the scope of this invention the auxiliary charge could be supported from a false bottom which is sustained on projections extending a suitable distance within the shell to hold 5 the auxiliary charge away from thdpercussion-cap chamber, it being obvious that in such a case the side walls of the bell-shaped hollow chamber would be present in the walls of the cartridge-chamber itself and the dome of the chamber constituted by the false bottom.

Having described the invention, the following is whatis claimed as new therein:

1. A cartridge orcartouche having a hollow chamber provided between the driving charge and the percussion-cap, and an auxiliary or priming charge supported within the chamber from the dome thereof to prevent the said auxiliary charge from contacting with parts that tend to injure it in transportation of the cartridge or cartouche.

2. A cartridge or cartouche, provided with an inserted part forming a hollow chamber between the driving charge and the base of the shell, and having an auxiliary or priming 3. A cartridge or cartouche, provided with I a bell-shaped inserted part providing a chamber between the driving charge and the percussion-cap and having an auxiliary or priming charge supported by said inserted part and held thereby out of contact with other parts which would tend to injure the auxiliary charge.

4. A cartridge or cartouche, provided with a bell-shaped part inserted between the driving charge and the percussion-cap; said inserted part being formed with a depression and having an auxiliary charge located in said depression for the purpose set forth.

The foregoing specification signed at Diisseldorf this 21st day of April, 1904.
