Improvements in Cartridge and Cartridge-case Extractors for
Breech-loading Fire-arms.
I, CHARLES FRANCOTTE, of 65, Mont St. Martin, Liège, in the Kingdom of
Belgium, Gunmaker, 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 has for its object an arrangement of the extractors of fire-arms
having pivotting breech-blocks, which allows of the employment in those arms of
cartridges with throats.
.
In the drawings the invention is represented in its application to a Martini-
Francotte gun.
Figure 1 represents a side view of the mechanism with the breech-block closed,
the left-hand side of the box being supposed to be removed; Figure 2 is a section
through A, B, C, D, of Figure 1 showing the cartridge extractor pushed to the
right and engaged in the throat of the cartridge, and Figure 3 is a front view of
the mechanism in the position it occupies in Figures 1 and 2.
Figure 4 is the same view as Figure 1, but with the breech-block lowered, that
is to say after the ejection of the cartridge.
Figure 5 is a section at EF of Figure 4 showing the cartridge extractor pushed
to the left, that is to say, into a position where it is not engaged in the throat af
the cartridge, and is out of the path traversed by the latter in entering, and leaving
the chamber of the barrel.
Figure 6 is a front view of the mechanism in the position it occupies in Figure 4.
Figure 7 shows three detached views of the extractor.
The extractor, Figure 7, consists of a lever with two arms a and i, one hori-
zontal, the other vertical; it is placed loose on an axis b on which it can pivot, and
on which it can slide laterally. The horizontal arm a is furnished on its right hand
side with a projection a¹ terminating near the bottem in an inclined plane a
which, at the moment of expulsion of the cartridge case, pushes the extractor to
the left and disengages the claw of the latter from the throat of the cartridge
case.
The vertical arm has the shape of a fork the branches c and i of which are
sufficiently separated to allow the free passage between them of the cartridge when

page_text: the gun is being loaded. The branch c serves only as a guide for the extractor;
it is terminated at the top by a projection c¹ at the back which, when the breech-
block d is being closed, slides on an inclined surface d' (Figures
and 3) of the
latter, and forces the extractor to slide on its axis towards the right, so as to cause
the claw of the extractor to enter the throat of the cartridge. The branch i
carries the claw ¹ of the extractor.
OPERATION.
The breech-block d being open, the extractor a, i, c, occupies, on its axis b, its
extreme position towards the left, and the cartridge that is introduced into the
barrel passes freely between the branches i, c of the extractor. When the breech-
block is closed, (Figures 1 to 3) the projection c¹ of the branch c slides on the
inclined plane d₁ of the breech-block, and moves the extractor a, i, c, towards
the right, whilst the claw of the latter enters and remains in the throat of the
cartridge.
The gun having been fired, if the breech-block d is lowered, (Figures 4 to 6)
it strikes the arm a and pushes it downwards. Then the projection a¹ with
inclined plane a² comes against the inclined plane o (Figures 2 and 5) of the
vertical side of the trigger plate, and the extractor a, i, c, is pushed towards the
left at the exact moment when the cartridge-case already extracted is expelled;
so that the cartridge case passes freely between the branches of the extractor,
because the claw is disengaged from the throat of the cartridge case.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is
The improved cartridge and cartridge-case extracting mechanism for breech-
Ichding fire-arms, which consists of a two-armed extractor arranged to slide
laterally on its axis and having its vertical arm forked or divided into two branches,
one of which is provided with a claw adapted to take into the throat of the
cartridge or cartridge-case, and the other with a projection adapted to be acted upon
by an inclined plane on the breech-block as the latter closes, in order to move the
extractor laterally on its axis so as to bring the said claw into engagement with
the throat of the cartridge or cartridge case, and the horizontal arm of the extractor
being provided with a bevelled projection adapted to slide against an inclined
plane on the side of the trigger plate as the breech-block is opened, in order to
move the extractor laterally on its axis so as to bring the said claw chat of engage-
ment with the throat of the cartridge or cartridge-case, substantially as described.
Dated this 1st day of January 1898.
