Improvements in the Construction of Case Shot for Artillery
Purposes.
1 MARTIN MARTIN, Major of Royal Engineers, of Howwood, Renfrewshire,
Scotland, do hereby declare the nature of this invention, to be as follows :-
The object of my invention is to so construct case shot for artillery purposes,
that it is more effective by spreading the shot over a wider range, to the right and
left in front of the point of discharge, but with less spread as far as lowness and
height, so that there is much less waste of shot thrown low upon the ground, or
carried high over the heads of the enemy, as in the present construction.
I strengthen the case or cartridge containing the shot at both top and bottom
and leave it weak at each side where I wish it to burst, so that the pattern of
delivery of bullets, is elongated in width but narrowed in depth, thus giving a more
destructive effect.
Dated this First day of March 1895.

Improvements in the Construction of Case Shot for Artillery
Purposes.
.
I MARTIN MARTIN, Major, Royal Engineers of Howwood Renfrewshire,
Scotland, 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 ;-
The object of my invention is to so construct case shot for artillery purposes,
that it is more effective by spreading the shot over a wider range to the right and
left in front of the point of discharge, but with less spread as far as lowness and
height, so that there is much less waste of shot thrown low upon the ground, or
carried high over the heads of the enemy, as in the present construction.
DESCRIPTION OF DRAWINGS.
Fig. 1 is an elevation in section of my improved shell or case shot.
Fig. 2 is a modification of Fig. 1.
Fig. 3 is a diagram of pattern of delivery of bullets by the ordinary case shot.
Fig. 4 is a diagram of pattern of delivery of bullets by my improved case shot.
1 preferably strengthen the case or shell E containing the shot, at both top and
bottom, by casting or attaching strengthening pieces to same, thus leaving the
shell or case shot weak at each side G where I wish it to burst, so that the pattern
of delivery of the bullets is elongated in width but narrowed in depth as shown at
Fig. 4, thus giving a more destructive effect.

page_text: Or in place of the shell, being strengthened at top and bottom as shown at Fig. 1.
I may form a longitudinal groove or recess H, (see Fig. 2), along the inner surface
of the case shot, preferably at each side, for the purposes before described.
In Figs. 3 and 4, A. B is the head line of an enemy and C. D, the ground
line.
Having now particularly described and ascertained the nature of this inveu-
tion, and in what manner the same is to be performed, I declare that what I
claim is :—
Constructing case shot for artillery weaker at the sides so that when bursting,
the shot spreads over a wider range to the right and left, but with less spread-in
lowness and height, consequently less waste, and more deadly in effect, substantially
as shown and described.
