I GEORGE QUICK of Chipping Campden, in the county of Gloucester, a Fleet
Engineer in the Royal Navy, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in that class of cartridges for ordnance
which are made from discs or rings of compressed powder the object of the improve-
ments being to prevent any sliding or twisting motion of the said discs or rings in
respect of each other and to give great rigidity to the whole cartridge.
For this purpose I form recesses and projections on one side of the discs with
corresponding projections and recesses on the other side so that the male part of one
disc shall fit into and interlock with the female part of another disc so as to prevent
side play or any twisting movement. But I prefer to make the centre part of one
side of the discs somewhat deeper than the centre part of the other side so that whilst
the discs are in close contact at the outer edge there is a small space between the
discs at the central parts to allow the flame of ignition to play freely over the surfaces.
The discs at the edges may be caused to adhere together by pressure, or by the use of
some adhesive material.

page_text: I, GEORGE QUICK, of Chipping Campden, in the County of Gloucester, a Fleet
Engineer in the Royal Navy 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 :-
This invention relates to improvements in that class of cartridges for ordnance
which are made from discs or rings of compressed powder the object of the improve-
ments being to prevent any sliding or twisting motion of the said discs or rings in
respect of each other and to give great rigidity to the whole cartridge.
For this purpose I form recesses and projections on one side of the discs with
corresponding projections and recesses on the other side so that the male part of one
disc'shall fit into and interlock with the female part of another disc so as to prevent
side play or any twisting movement. But I prefer to make the centre part of one
side of the discs somewhat deeper than the centre part of the other side so that whilst
the discs are in close contact at the outer edge there is a small space between the discs
at the central parts to allow the flame of ignition to play freely over the surfaces.
The discs at the edges may be caused to adhere together by pressure, or by the use of
some adhesive material.
And in order that my invention may be thoroughly understood and carried into
practical effect I have caused to be annexed to this specification the accompanying
two sheets of drawings and now refer to the figures and letters of reference marked
thereon.
In these figures similar letters of reference indicate corresponding parts.
Fig. 1 is an elevation of the rear end cake, disc or ring of compressed powder or
other propelling composition, the large hole in the centre being provided for the
insertion if required of a primer and the concentric circles of smaller holes serving
as air-spacing and to facilitate ignition and combustion.
Fig. 2 is an elevation of an intermediate cake with large central hole and con-
centric circles of smaller holes serving as air-spacing and to facilitate ignition and
combustion.
Fig. 3 is a side elevation of an intermediate cake so formed.
Fig. 4 represents the two ends of a cartridge built up of cakes of powder or other
propelling composition formed as indicated in Figs. 1, 2 and 3.
A, A are the male projections, which engage with corresponding female recesses on
the opposite side of the next cake. B, B are the female recesses which likewise
engage with corresponding male projections on the opposite side of the next cake.
These interlocking surfaces are dished, hollowed out or coned at the centre so as to
form an additional amount of air-spacing and to allow the flame of ignition generated
by the explosion of the primer to extend itself from the centre of and between the
interlocking snrfaces of the powder cakes. "a¹," "61" represent the flat portions of

page_text: the interlocking surfaces of the powder cakes and "a³," "b" the coned, hollowed out
or dished portions of the saine.
I have shown only one side of the powder cakes as being provided with this coning,
dishing or hollowing out, but I might apply it to both sides and instead of applying
it to all the interlocking surfaces might apply it to only half or less than half
the number.
If desired the flat surfaces at "a¹," "61" before mentioned can be united together
by any suitable adhesive solution.
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 :-
Forming the sufaces of the individual cakes of compressed powder or other propelling
composition constituting a cartridge with male and female interlocking surfaces, each
of these surfaces on the one cake being adapted to engage with a corresponding surface
on the next cake, the said interlocking surfaces being formed either plain or with a
central coning, dishing, or hollowing out, substantially as and for the purposes
described.
