I, CECIL SANDYS WALKER, of 14, Edwardes Square, Kensington, in the County
of London, Engineer, do hereby declare the nature of this invention to be as
follows:-
The bullet is composed of two parts which are secured together by screwing
or otherwise. One part, forming the rear end of the bullet and also the axis
or central stalk of the bullet, I make of a tough alloy suitable for taking the
rifling of the barrel without stripping or fouling. The rear part is made of
sufficient diameter to take the rifling similarly as the rings on large projectiles
take the rifling in ordnance, that is, by compression. But in order to provide
for the wearing away of the rifling or enlargement of the breech end of the
barrel I may form the base of the rear part cup-shaped so that it may expand
by the pressure of the gas and assist to seal the bore gas-tight thus preventing
erosion and prolonging the life of the barrel. The front part of the bullet is
formed of lead or some suitable alloy and is screwed or otherwise secured to
the base and centre stalk of hard alloy.

Improvements in Buffets for alarms and machine Guns.
I, CECIL SANDYS WALKER, of 14, Edwardes Square, Kensington, in the County
of London, 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 bullet is composed of two parts which are secured together by screwing

sufficient diameter to take the rifling similarly as the rings on large projectiles

for the wearing away of the rifling or enlargement of the breech end of the
barrel I may form the base of the rear part cup-shaped so that it may expand

page_text: the base and central stalk of hard alloy. To enable my invention to be fully
understood I will describe it by reference to the accompanying drawing, in
which:
Figure 1 is a longitudinal section of a bullet showing the principle of this
system of construction in its simplest form.
Figure 2 is also a longitudinal section showing the rear part of the bullet cup-
shaped so that it may expand freely to fill up the bore completely in cases
where the rifling or bore has been worn away.
Figure 3 is a modification of Figure 2, and
Figure 4 is another modification of the same Figure 2.
The base and stalk A A are formed by means of a press and suitable dies,
the stalk having a screw thread or grooves impressed thereon. The body B B
of the bullet is pressed as hollow bullets usually are pressed and is placed on
the stalk and pressure applied by dies or otherwise so that the metal of the
body B B is forced into the screw thread or grooves in the stalk A A, and is
thus securely attached thereto.
It is obvious that the stalk may extend through the whole length of the bullet
or only part of the length as shown in Figure 2. The screw thread on the stalk
can be, of course, made either right or left handed to suit the rifling of the barrel,
or one part of the thread can be made right handed and the other left handed
so that the bullet would suit any kind of rifling.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is―
1. A bullet having a base and stalk as described, with a fore body or front
part secured thereto as herein before described.
2. In a bullet the combination of a base and stalk of one kind of metal or alloy
with a fore body or front part of a different metal or alloy.
