COMPLETE SPECIFICATION filed by the said William Robert Lake

Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED
CARTRIDGE FOR FIRE-ARMS," and have petitioned Her Majesty to grant
) unto me, my executors, administrators, and assigns, Her Royal Letters

page_text: Patent for the same, and have made solemn Declaration that it has
been communicated to me from abroad by Charles Walley Lovett,
junior, of Boston, Massachusetts, United States of America.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention and
in what manner the same is to be performed in and by the following
statement, reference being had to the accompanying Drawing, forming
a part of this Specification.
The nature of my Invention consists in producing a case or cartridge
in which shot, bullets, balls, or other projectiles are enclosed in a spiral
or coil composed of two or more spirals or coils of wire, rods, strips of
metal, or other suitable material joined at one of the ends, the opposite
ends being left free and disunited to allow the coils or spirals on the
cartridge being discharged from the gun to separate and spring some-
what apart, and divide the cartridge or case into three or more separate
compartments or cages.
The mode of construction is as follows:-I twist two or more lengths
of wire, rods, or strips of metal, or other suitable material around a
mandril, taking care to have the said mandril smaller in circumference
than the intended coil or spiral to allow for its tendency to enlarge upon
being released. I then upon a slightly larger mandril make a very light
case of paper, cloth, or other similar material, and place or enclose the
coil or coils within it. The case is then packed with shot mixed with
powdered chalk, tripoli, or other finely divided dry equivalent material,
and a common paper or other gun wad is placed over the shot, the whole
being secured by turning the ends of the case over, and fastening them
with paste or gum. The cartridges are then labelled with the gauge of
the gun and the weight and size of the shot, and are ready for use.
'
Figure 1 represents the case or coil of two wires before it is filled
with shot and enclosed in the wrapper. A shows the point of juncture
of the separate coils, and B the separate opposite ends of the coils or
spirals.

page_text: same, I wish it understood that I claim, a cartridge consisting of two or
more spirals or coils of wire or other similar material, substantially as
above described.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and seal, this Thenty-third day of March, in
the year of our Lord One thousand eight hundred and seventy-
Witness,
EDWARD C. JACKSON.
