page_text: We, JAMES LANG of 18 Brook Street, Hanover Square, in the County of Middlesex,
and ARTHUR JEFFRIES, of 91 Tyneham Road, Battersea, in the County of Surrey,
Gun Makers, do hereby declare the nature of this invention to be as follows:-
Our Invention consists of the improvements hereinafter described in extracting
mechanism of, what are known as, "drop down" small arms whereby the case of the
exploded cartridge is ejected on raising the breech end of the barrels for recharging.
In the ordinary extractor of "drop down" guns the exploded cartridge is started
on raising the breech ends of the barrels, the complete removal of the case being
effected by hand.
We employ the ordinary mechanism for starting the case but supplement it
by the mechanism hereinafter described whereby the started cartridge case is
ejected from the barrel.
On the underside of the barrel we fit a spring in front of the leg of the extractor,
the end of the spring nearest the extractor leg has an enlarged end to admit of a
notch or bent being formed in it to enable it to be held back when cramped.
The spring is compressed by closing the barrel when the extractor leg presses
upon the spring and causes it to be cramped. It is then held in position
by a lever that has a projection on it corresponding to the notch in the
spring and acts like an ordinary sear in a gun lock; this projection engages
in the notch in the spring when the latter is compressed and holds it in
position. The said lever is acted upon by a sliding plate in the body of the
action, the upper end of which is in front of the axle of the tumbler of the
lock whilst the lower end or nose of the sliding plate is under the end of
the before mentioned lever when the parts are in the position they occupy after
the gun has been discharged.

page_text: On lifting the breech ends of the barrels for recharging the same the end
of the sliding plate strikes the lever and causes it to be disengaged from the
notch in the spring. The said spring is then released when it urges forward the
extractor rod with a sudden motion and thereby ejects the cartridge case; on
closing the breech ends the abutment of the fore end forces the said sliding
plate back so that it is not within the range of motion of the said lever
and the ejector mechanism is not acted upon by raising the breech ends of
the barrels until the said plate is pressed forward to its original position by
the axle of the tumbler (which is can shaped) pressing upon its upper end
when the tumbler revolves to discharge the gun.
The action of the gun is as follows:-
When the gun is fired the axle of the tumbler forces forward the sliding
plate that works through the body of the action thereby bringing the lower
end or nose of the said plate within range of the lever.
On raising the breech. ends of the barrels the ordinary mechanism starts the
cartridge case and the end of the lever striking against the lower end or nose of the
sliding plate the said lever is disengaged from the bend in the spring which
by striking against the extractor leg ejects the cartridge case.
The sliding plate is forced back in the way described, by the abutment on
the fore end after recharging the barrels when the breech ends are being shut.
The spring is forced back by the extractor leg and its notch engages with the pro-
jection on the lever. Until the sliding plate has been forced forward by the axle
of the tumbler the ejector mechanism cannot act.
The breech ends of the barrels may be raised any number of times without ejecting
the unexploded cartridge but when the gun is fired the axle of the tumbler
revolves and the cam shaped end thereof forces the sliding plate forward so
that the exploded case will be ejected.
This invention is applicable to single and double "drop down"
guns.
We also employ a bolt or lever to act when required as a stop to prevent the action
of the spring acting on the extractor leg, so that the gun may, when required, be
used without the ejector mechanism.

page_text: We JAMES LANG of 18 Brook Street, Hanover Square, in the County of Middlesex,
and ARTHUR JEFFRIES of 91, Tyneham Road, Battersea, in the County of Surrey,
Gun Makers, 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, reference being had to the accompanying drawings, and to
the figures and letters marked thereon :-
"
Our invention consists of the improvements hereinafter described in extracting
mechanism of what are known as Drop down" small arms, whereby the case
of the exploded cartridge is ejected on raising the breech end of the barrels for
recharging.
In the ordinary extractor of "Drop down" guns the exploded cartridge is
started on raising the breech ends of the barrels, the complete removal of the
case being effected by hand. In some
cases however mechanical means are
employed to effect the complete removal of the cartridge case.
According to our invention, we also employ the ordinary mechanism for starting
the case but supplement it by the improved mechanism hereinafter described, whereby
the started cartridge case is ejected from the barrel.
Figure 1 is a longitudinal section of parts of a double barrelled "drop down"
showing our improvements applied thereto,
gun
Figure 2 is a longitudinal section showing the parts in the position ready for
firing.
Figure 3 is a similar section to figure 2, showing the parts in the position just after
firing, but before the breaking down of the barrels.
Figure 4 is a longitudinal section representing the parts in the position they would
assume after firing and the partial breaking down of the barrels, but just before the
ejector mechanism is caused to act.
Figure 5 is a face view of the body of the gun.
Figures 6, 7 and 8 are respectively a side view, an end view, and a plan of part
of the fore end and parts carried thereby, and Figure 9 represents a slight
modification.
In all the figures like parts are indicated by similar letters of reference.
a is one of the barrels, b is the body of the gun, c is one of the tumblers or strikers,
which are operated in the usual manner, d is one of the cocking levers which act to
cock the tumblers or strikers on the raising of the breech ends of the barrels as is well
understood, e is the fore end.

page_text: On the underside of the barrels we fix to the fore end a spring fin front of the leg
of each extractor; the end of the spring nearest the extractor leg g has an enlarged
end to admit of a notch or bent being formed in it, to enable it to be held back
when cramped.
The spring fis compressed by closing the barrels when the end of the extractor
leg 9 presses upon the enlarged end f¹ of the spring fand causes it to be cramped, in
which position it is held by a lever that has a projection on it corresponding to
the notch or bent in the enlarged end f¹ of the spring f, and acts like an ordinary
sear in a gun lock; this projection engages in the notch f' in the enlarged end of
the spring f, when the latter is compressed and holds it in position. The said lever /
is acted upon
in one direction by a spring 2, and in the other by a sliding plate i in
the body b of the action, the upper end of which is in front of the tumbler of the lock,
whilst the lower end or nose of the sliding plate is under the end of the before
mentioned lever, when the parts are in the position they occupy after the gun has
been discharged, (see figures 3 and 4).
On lifting the breech ends of the barrels a for recharging the same, the end of the
sliding plate i strikes the lever hand causes it to be disengaged from the notch f³ in
the enlarged end f¹ of the spring f.
The said spring is then released when its enlarged end f₁ strikes against, and urges
forward, the extractor rod or leg g with a sudden motion and thereby ejects the
cartridge case; on closing the breech ends of the barrels a cam shaped enlargement c¹
on the axle of the tumbler c, (see figure 9) or a lump c² on the side of the tumbler c
(see Figures 1, 2, 3, 4) forces the said sliding plate back, so that it is not within the
range of motion of the said lever h, and the ejector mechanism is not acted upon by
raising the breech ends of the barrels until the said plate i is pressed forward by the
tumbler c pressing upon its upper end when the tumbler revolves to discharge
the gun.
The upper end of the plate i is formed as shown to extend on both sides of the
cam shaped enlargement c¹, or of the lump c, in order that such enlargement c¹ or
lump c² may be capable of operating the plate i in both directions.
The action of the gun is as follows:-
When the
or the lump is fired the cam shaped enlargement c on the axle of the tumbler c
forces forward the sliding plate i, thereby bringing the lower end or
nose of the said plate within range of the lever h.
On raising the breech ends of the barrels the ordinary mechanism, consisting of a
projection on the body of the gun acting within a notch in the extractor leg, starts
the cartridge case, and the end of the lever h, striking against the lower end or nose i
of the sliding plate i, the said lever h is disengaged from the notch or bent in the
spring, the enlarged end f¹ of which, by striking against the extractor leg g, ejects
the cartridge case.
The sliding plate i is forced back in the way described by the tumbler after
recharging the barrels when the breech ends are being shut.
The spring is forced back by the extractor leg g and its notch or bent f³ engages
with the projection on the lever h.
Until the sliding plate i has been forced forward by the tumbler, the ejector
mechanism cannot act.
The breech ends of the barrels may be raised any number of times without ejecting
the unexploded cartridge, but when the gun is fired, the tumbler revolves and forces
the sliding plate i forward so that the exploded case will be ejected.
This invention is applicable to single and double "drop down" guns, as will be
well understood.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
:
"
1. In the ejector mechanism of "drop down guns, the peculiar construction,
arrangement, and combination of parts, substantially as herein shown and described.

page_text: 2. In the extractor mechanism of "drop down" guns, a spring f with an enlarged
end f¹ to act on the extractor leg g, and a notch or bent in which engages a
projection of a lever h, which latter is kept in engagement with the notch or
bent by a spring h³, and is released therefrom by the end of a sliding plate i acted
upon by the tumbler substantially as herein shown and described.
3. In the ejector mechanism of "drop down" guns, the combination of a spring f
and lever constructed and acting substantially as herein shown and described.
