PROVISIONAL SPECIFICATION.
Improved Cartridge for Revolvers, Magazine Rifles, and Machine
Guns.
We, NIGEL CRAWFORD LINDSAY and HENRY STANBRIDGE trading as
Lindsay Stanbridge & Co., 38 Wellesley Road Chiswick London Engineers
do hereby declare the nature of this invention to be as follows:-
Our invention consists in so placing a certain number of cartridges into a metal
plate that they are made to form a whole. This can be effected by various means
by preference during the process of heading and finishing the base of the cartridges.
The heads of the cartridges need not necessarily project beyond the plate but can
be kept flush with the same if necessary. Also the cartridges and plate could be
united by the cap chamber as in the case of the Snyder or Martini Boxer cartridge.
The plate can be circular, polygonal star or other suitable shape to decrease weight
and in the case of revolver cartridges provided with a central hole for the ratchet
wheel. Also for magazine rifles, notches or other devices may be cut or holes
punched to facilitate revolving the cartridge.
Dated this Twenty-third day of June 1894.

Improved Cartridge for Revolvers, Magazine Rifles, and Machine
Guns.
We NIGEL CRAWFORD LINDSAY and HENRY STANBRIDGE, both of
136 formerly numbered 38 Wellesley Road Chiswick London, W. Engineers,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
Our invention consists in so placing a certain number of cartridges into a metal
plate that they are made to form a whole. This can be effected by various means,
by preference during the process of heading and finishing the base of the cartridges.
The heads of the cartridges need not necessarily project beyond the plate but can
be kept flush with the same if necessary.
Also the cartridges and plate could be united by the cap chamber, as in the case
of the base of the Snyder, & Martini Boxer cartridges. The plate can be circular,
polygonal, star or other suitable shape to decrease weight and in the case of revolver
cartridges provided with a central hole for the ratchet wheel also for magazine
rifles, notches or similar devices may be cut or holes punched to facilitate the
revolving of the cartridge.
In order to enable our invention to be fully understood, we will proceed to
describe how it can be carried into practical effect by reference to the accompanying
drawing.

Fig. 1. is a front view of a revolver cartridge.
Fig. 2 is a side view of same, partly in section.
Fig. 3 is a front view of a magazine rifle cartridge.
Fig. 4 is a side view of same.
Figs. 5. 6. 7 shew different modes of attaching the cartridges to plate.
Fig. 8 also shews mode of attaching the cartridges to plate by means of a cap
chamber.
Similar letters in the figures represent similar parts.
A represents the plate, by preference of steel, thin and tempered, for lightness
and strength.
B represents the brass or aluminium cartridge case or shell.
e represents the cap chamber, as a separate piece from the cartridge shell.
In Figures 1. 2 and 5 the cap chamber is shewn with a projection, a, which is
burred or flanged over as shewn at, b, thereby connecting the cartridge shell and
plate.
In Figure 6, a variation is shewn, the holes in the plate being flanged at c. c. to
strengthen the walls of the cartridge shell and the cartridge shell is attached by
the head instead of cap chamber. Soft metal like aluminium can thus be used for
the cartridge shell.
In Figure 7 a modification is shewn whereby the base of cartridge is strengthened
by the flanges d. d. curved out from plate and imbedded in the base of
cartridge.
Figure 8. shews the cartridge shell and plate united by the cap chamber "e."
It is of course easily possible to make many modificatious or combinations too
numerous to mention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :--
1. Uniting cartridge cases or shells at their bases to a metal plate by rivetting,
burring or flanging either the plate, or the cartridge case, or both, so that the plate
and cartridge cases form one piece and thus enable two or more cartridges to be
placed at one time into a firearm or machine gun.

ninety-five (1895).
