Improvements in Breakdown Sporting Guns.
I, STEPHEN GRANT Junior, Gun Maker, of 67* St. James Street in the
County of Middlesex, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to simplify the cartridge extractor mechanism of
breakdown sporting guns, and the invention relates to the well-known divided
extractor, the parts of which are operated only after the cartridges have been
fired.
The parts of the extractor are operated under the influence of suitable springs,
by rods provided with bents, into which take suitable sears, such sears being
released when the "breaking down" takes place, as is now well understood.
In carrying out this invention, I make use of the cocking lever to partially act on
the sear, and cause it to project through a slot in the fore-end, so that the tail
(which is prolonged for the purpose) will strike a shoulder on the action, when the
breech is operated, and release the spring rod, which acts on one part of the
divided extractor.
The sear is provided with a lateral projection, against which the nose of
the cocking lever, (projecting through a slot in the fore-end) bears, to partially
release the sear when the hammer has fallen.
The slot also retains the lever in the position to act on, & cock the hammer,
when the breech is opened.
By these means, the sliding piece which is usual in this class of gun for operating
on the extractor, is dispensed with.

. Improvements in Breakdown Sporting Guns.
I STEPHEN GRANT Junior, Gun Maker, of 67ª St. James Street, in the
County of Middlesex, 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 :-
The object of this invention is to simplify the cartridge extractor mechanism of
breakdown sporting guns, and the invention relates to the well-known divided
extractor, the parts of which are operated only after the cartridges have been
fired.
The parts of the extractor are operated, under the influence of suitable springs,
by rods provided with bents into which take suitable sears, such sears being
released when the "breaking down" takes place, as is now well understood.
In carrying out this invention, I make use of the cocking lever to partially act
on the sear, and cause it to project through a slot in the fore-end, so that the tail
(which is prolonged for the purpose) will strike against a shoulder on the action,
when the breech is operated, and release the spring rod which acts on one part of
the divided extractor.
The sear is provided with a lateral projection against which the nose of the
cocking lever (projecting through a slot in the fore end) bears, to partially release
the sear, when the hammer has fallen.
The slot also retains the lever in the position to act on, and cock the hammer,
when the breech is opened.

page_text: By these means, the sliding piece which is usual in this class of gun for operating
on the extractor, is dispensed with.
And in order that my invention may be clearly understood, I will now proceed
to more fully describe it, reference being had to the accompanying drawing, in
which
Fig. 1 is a side elevation, partly in section, of so much of a breakdown sporting
gun, as is necessary to illustrate my invention, the parts being in the position they
assume when the gun is loaded.
Fig. 2 is a similar view, the gun having been fired.
Fig. 3 is a similar view, the gun being ready for loading.
Fig. 4 is a front or end view of the action.
Fig. 5 is a rear or end view of the fore-end; and
Fig.
6 shews, in plan, the relative positions of the sears and cocking levers.
A is the action, and B the fore-end, which are of the usual construction generally.
C is a cocking lever, which is mounted on a pivot pin in the action. The tail e of
this lever underlies the hammer, so that when the lever is rocked, it will cock the
hammer in the usual way. The nose c¹ of the lever C projects through the front
plate a of the action A, and through a slot in the fore-end B, as will be more
particularly referred to.
D is a sear, which is pivotted at d to the fore-end B. The nose of this sear
takes into a bent on the extractor mechanism. The form of the sear is clearly
shewn in Fig. 6, and the tail d' passes through the slot in the fore-end B, and
enters the slot in the plate a of the action. At the side of the tail d' of the sear is
a projection, which, when the parts are in position, overlies and bears against the
nose c¹ of the cocking lever C.
It will be seen from Fig. 1, that when the gun is loaded and cocked, the point of
the tail of the sear D is well within the fore-end B. When the gun has been
fired, as in Fig. 2, the hammer, on falling, strikes on the tail c of the cocking
lever C, and depresses it slightly, thus causing the nose e¹ to rise. The nose c
being in contact with the projection on the sear D, tips (when it rises) the sear,
and partially releases it. At the same time, it brings the point of the tail d¹ in
position to strike against a shoulder formed by the bottom of the slot in the plate a
of the action, so that when "breaking down" takes place, the point of the sear
strikes against this shoulder, and the sear is withdrawn from the bent of the
extractor mechanism, which is then free to shoot forward and throw out the
empty cartridge case.
It will be obvious that in the arrangement herein shewn and described, the
ejecting of the cartridge case, on the breaking-down, will only take place after
the hammer has fallen, as, until then, the cocking lever will be free to rock, and
will not act on the sear, to bring it into position to strike against the shoulder, and
thus release the bent of the extractor mechanism.
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 :-
1. The means substantially as herein shewn and described, for releasing the
extractor mechanism of break-down sporting guns.
2. In break-down sporting guns, the use of the cocking lever to partially release
the sear, and bring it into position to be entirely released from the extractor
mechanism, on the "breaking down" of the gun, as herein set forth.
3. In break-down sporting guns, the application thereto of a sear adapted to be
partially released by the cocking lever, and completely released by striking
against a shoulder on the action, as set forth.
