IMPROVEMENTS IN THE EXTRACTING MECHANISM OF BREECH LOADING SMALL ARMS
Year: 1885

page_text: I JULIUS COSTER Gunmaker 20 Hillside Street Edinburgh Scotland do hereby
declare the nature of my invention for IMPROVEMENTS IN THE EXTRACTING
MECHANISM OF BREECH LOADING SMALL ARMS to be as follows:-
The "Extracting Lever" is fitted into Martini action immediately in front of
sceir point by means of a pin passing through the same and action upon which
the "Extracting Lever" oscillates, having one or two prongs extending backward
from said pin passing along on either or both sides of sceir and tumbler
respectively, till they meet and protrude over projections or either of them on
lever, or a projection which may be constructed on each or either side of
tumbler. The "Extracting Lever" has also an extension from said pin forward
to meet and rest upon present extractor, thus in opening breech by means of
lever. The projection on side of lever or tumbler or either of them will come
into contact with prongs of " Extracting Lever" and raise the same while
depressing the front portion of it and the extractor along with it.

Improvements in the Extracting Mechanism of Breech-loading
Small-arms.
I, JULIUS COSTER, Number twenty Hillside Street, Edinburgh, Gunmaker, do
hereby declare the nature of my invention for IMPROVEMENTS IN THE EXTRACTING
MECHANISM OF BREECH-LOADING SMALL ARMS, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-
To extract the cartridge-case from the barrel of any rifle fitted with a Martini
action, or any action to which the invention may be applied, I have fitted the
extracting lever B. into the Martini action, by means of the pin D. which passes
through the action body or trigger-plate, or both of them, upon which the
extracting lever B. oscillates. The extracting lever B. has a prong b. extending
backward from said pin D. passing along either or both sides of sceir E, and
tumbler F. respectively, till they or either of them protrude over projection a. on
lever A. The said extracting lever B. has also an extension forward from said
pin D till the same protrudes over and rests upon extractor C. at.point d.―Thus
when the breech is open and the arm at full cock (as shewn in Sketch 2.) by
depressing lever A. the projection a. will act upon prong b. of extracting lever B.
and raise the sanie, while it depresses point c. which acting upon extractor C. at
point d. depresses the extractor C. at point d. A projection may also be con-
structed on either or both sides of tumbler E for the purpose of acting upon
extracting lever B. and by that means raise the said extracting lever B. at
point b. The amount of motion of the extractor C. is regulated by the distance
the extracting lever B. protrudes over the extractor C., thus the cartridge-case may
be wholly or partially extracted by means of extracting lever B. A projection
may also be constructed on either or both sides of lever A. for the purpose of
acting upon extracting lever B. at point b.-This invention is also applicable to
other breech mechanisms.
Figure 1. on Drawing shews the connection between lever A. and extractor C.
by means of extracting lever B.
Figure 2. on Drawing shews the position of lever A. extracting lever B., and
extractor C. and the various limbs referred to in specification.
Figure 3. on Drawing shews a top view of extracting lever B.
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
I. The extracting lever B. for the purpose of forming a connection between
lever A. and extractor C. in its present or any suitable shape or form, to effect the

page_text: extraction of the cartridge-case, thereby gaining greatly increased power in
extracting the cartridge-case.
II. The utilizing of the projection a on lever A to act upon extracting lever B
and any enlargement or alteration in shape or form of the same.
III. Any piece or projection fitted to lever A. for the purpose of acting upon
extracting lever B. to effect the extraction of the cartridge-case.
IV. The depressing of the extractor C. at point & by means of extracting
lever B.
