WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. " IMPROVEMENTS IN ANVILS FOR PAPER CAR-
TRIDGES." A communication from abroad by Julien Saget, of [New Orleans,
Louisiana, United States of America.
This Invention relates to anvils for use in paper shell cartridges, the peculiar
construction and advantages thereof being fully set forth in the following description,
reference being had to the accompanying Drawing, in which
Figure 1 is a perspective view of an ordinary paper cartridge shell.
Figure 2 is a sectional view of the same provided with my improved anvil.
Figure 3 is a device for disengaging the old caps.
Figure 4 is the cup or socket of the shell in which the anvil and firing cap
are held.
Figure 5 shows my improved anvil detached.
Like letters indicate the same parts throughout the Drawing.
The said Invention consists in providing in a single piece an anvil of brass, iron,
or steel, the head a of which is somewhat larger in diameter than its stem b, and is
made slightly conical in form to receive thereupon the necessary cap for the explosion
of the charge contained within the shell to which the said anvil is applied.
The peculiar feature of my Invention is the formation across the head of the
anvil of a narrow groove c, which is continued down one side of the said head and
stem and to the very point of the latter; through this groove the fire is conveyed in
a straight line to the charge, causing the same to explode, without injury to the
shell.
The old cap is readily removed from the shell by means of the device shown in
Figure 3, and which is constructed of wood or other suitable material; its stem & is

page_text: made small enough to be readily inserted in the paper shell and its end is provided
in its centre with a socket (shown in dotted lines) the bottom of which receives the
point of the anvil, keeping it in a central position while it is being pushed outward
from the shell to disengage the old cap and leave the anvil ready for a new one.
Having thus fully described the said Invention, as communicated to me by my
foreign correspondent, and the manner of performing the same, wish it understood
that I am aware that detachable anvils have heretofore been inserted in the base
plate of cartridge shells, and I do not claim the same as my Invention, but I claim,
the improved anvil herein described, consisting of a conical head a and stem b, the
top of the former provided with a groove c which is continued down one side of the
head and stem, as above described, and for the purpose spécified.
In witness whereof, I, the said William Robert Lake, have hereunto set iny
hand and seal, this Eleventh day of April, in the year of our Lord One
thousand eight hundred and seventy-six.
Witness,
