Improvements in Projecties.
I, CHARLES HERBERT BAXTER, of Homestead Works, Sandiacre, in the
County of Derby, Engineer, do hereby declare the nature of this invention to be.
as follows:-
The invention relates to an improved construction of projectile which is capable
of being fired either from a smooth bore or from a rifled gun or fire-arm, the object
being to obtain great accuracy of flight, less resistance to its passage through the.
air, and greater penetrating power.
For this purpose I form the projectile of two or three twisted threads or blades,.
preferably constituting the entire body of the same, that is to say, without any
cylindrical centre, the projectile thus being somewhat in the form of a portion of a.
twisted auger or twist drill but of longer pitch; the projectile may be formed as a
solid shot or it may be formed with a central cavity for explosive to enable it to.
be used as a shell. The periphery or edges of the threads or blades may be smooth.
to enable the projectile to be fired from a smooth bore gun, or it may be provided
with soft metal studs or projections to fit into the grooves of a rifled gun. The
threads or blades are curved off at the fore end of the projectile to facilitate the
action of the latter. A sabot is fitted to the rear of the projectile.
Projectiles constructed according to my invention are applicable to either large.
or small arms.

Improvements in Projectiles.
I, CHARLES HERBERT BAXTER, of Homestead Works, Sandiacre, in the
County of Derby, Engineer, 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 invention relates to an improved construction of projectile which is capable
of being fired either from a smooth bore or from a rifled gun or firearm, the
object being to obtain great accuracy of flight, less resistance to its passage through
the air, and greater penetrating power.
For this purpose I form the projectile of two twisted threads or blades constituting
the entire body of the same, that is to say, without any cylindrical centre, the
projectile thus being somewhat in the form of a portion of a twisted auger or
twist drill; the projectile may be formed as a solid shot or it may be formed with.
a central cavity for explosive to enable it to be used as a shell. The periphery
or edges of the threads or blades may be smooth to enable the projectile to be fired
from a smooth bore gun, or it may be provided with soft metal studs or projections.
to fit into the grooves of a rifled gun. The threads or blades are preferably
curved off at the fore end of the projectile to facilitate the action of the latter..
A sabot is fitted to the rear of the projectile.

page_text: Projectiles constructed according to my invention are applicable to either large
or small arms.
My invention is illustrated in the accompanying drawings, in which :-
Figs. 1 and 2 are two side elevations drawn at right angles to each other of a
projectile to be fired from a smooth bore gun.
Fig. 3 is a front end view and Fig. 4 is a rear end view of the same.
Fig. 5 is a side view similar to Fig. 1 but with the addition of a sabot which is
shown in section, and
Fig. 6 is a plan and Fig. 7 is a cross section of the sabot separately.
According to my invention I form the entire body of the projectile of two
twisted threads or blades a, that is to say, its shape is similar to what would be
obtained by the twisting of a riband of metal upon its own axis, thereby producing
a body without any cylindrical centre and somewhat in the form of a portion of
a twisted auger or twist drill.
The projectile may be formed, as shown in the drawings, as a solid shot or it
may be formed with a central longitudinal cavity for explosive to enable
it to be used as a shell, in which case it may be formed of greater thickness
than that shown in the drawings in order to provide a larger chamber or cavity
for the explosive.
The periphery or edges of the threads or blades a may be made smooth as
represented in the drawings to enable the projectile to be fired from a smooth
bore gun; or the projectile may be provided with soft metal studs or projections
on the edges of the blades or threads to fit into the grooves of a rifled gun. The
threads or blades a are preferably curved off at the fore end a¹ of the projectile
to facilitate the action of the latter both in passing through the air and in
penetration, but if desired the fore end a¹ may extend the full width of the
projectile and be either flat or wedge form.
A sabot b is fitted to the rear of the projectile preferably in the manner shown
in the drawings.
It will be understood that the pitch given to the blades or threads of the
projectile may be varied, that shown in the drawings being only for purpose of
illustration. In the drawings 1 have represented the projectile with a section
consisting of parallel sides and curved ends, but I would have it understood
that the sides may be somewhat curved and be either convex or concave.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:―
A projectile constructed as herein described.
