Inventor and Impressario 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 :-
My Invention consists of a rubber or leather buffer placed inside the cartridge
case and is perforated for the flash of the cap to pass through it to the powder.
This buffer receives the shock of the explosion, which presses it together thereby
reducing the recoil. This buffer will also entirely prevent any possibility of the cap
blowing back. The shock of the explosion closes the perforation in the buffer that
the flash from the cap passes through and prevents any escape of gas backwards,
thereby preventing any cap from being blown back or bursting.
To prevent the expansion of the cartridge case, when heavy charges of powder are
used or explosives such as gun cotton. An elastic or india rubber tube is placed inside
the cartridge case between it and the powder, which will give to the first shock
the explosion and prevent the expansion of the cartridge case or the bursting of
the gun.
The said invention will be better understood, by reference to the accompanying
drawings.
Figs. (1 & 2) are horizontal sections of cartridges arranged according to my
invention.
Figs. (3 & 5) show elevations and plans of elastic tubes.
Fig. (3) shows also longitudinal sectional view on one side (of tube).
Fig. (4) is end or cross section.
Fig. (6) is plan and section of metallic buffers and elastic buffers in combination.
In Figs. (1 & 2) the rubber or elastic buffer is shewn in position at (c). c¹ is
another buffer placed on top of the powder if found necessary. (b) is elastic tube
that line the walls of the cartridge case. (g) is perforation in buffer. (a) is wall of
cartridge case. (d) shows position of wad or wax that is generally used.
Fig. (3) is plan side section and elevation of elastic tube, with indentations to give
into or close up when explosion takes place.

page_text: Fig. (5) is elevation and plan of corrugated elastic tube, corrugation for same
purpose as indentation-a single or double plain tube can also be used.
Fig. (4) is cross section of cartridge shewing tube in position, with powder
inside it.
Fig. (6) (C) 1, 2, 3 are three elastic buffers with metallic spring buffers (f, f)
between them. A plan of metallic spring buffer is shown at (f), it is a metal disc
slightly concave, with a worm shaped or circular corrugation. A plain concave disc
could be used.
This combination of elastic and metallic buffers can be used in guns of large calibre,
when the elastic buffer or buffers are not sufficient to receive the shock of the
explosion.
The elastic buffer can be made of india rubber, leather, or other suitable
material.
The elastic buffer for the prevention of the recoil, will also lessen the lateral
strain on the cartridge case when used alone, and is sufficient for small arms, unless
gun cotton or other powerful explosives are used.
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
(1st) An elastic buffer to reduce the recoil of rifles or other fire arms (to be
put inside the cartridge case).
(2nd) An elastic buffer to prevent the blowing back or bursting of the cap by
the explosion of the powder.
(3rd) Elastic and metallic buffers combined (to be put inside the cartridge case).
(4th) An elastic tube, to act as a buffer or cushion, (to be put inside the cartridge
case) to prevent lateral expansion.
(5th) The use of metallic springs for buffers inside the cartridge case.
(6th) The use of the elastic buffer separate or in combination with the elastic tube
or metallic buffer.
(7th) The use of india rubber leather or other suitable material for the buffers or
cushions (to be put inside the cartridge case).
(8th) The whole of the invention as herein described for the purpose named-viz.-
reducing the recoil of fire arms, prevent the expansion of cartridge case, and the
blowing of the cap back or bursting it by the explosion.
Dated this 21st day of June 1888.
