page_text: I, GEORGE JEFFRIES of Norwich in the County of Norfolk, Gun Maker do
hereby declare the nature of this invention to be as follows:-
My improvements relate mainly to improved means for ejecting the spent
cartridge and as regards a double barrelled fire arm ejecting them singly or
together.
On to an ordinary single or double barrel I braze the lump in the usual manner,
the said lump is made with a broad base piece which stands up above the barrel
at each side of the lumps. I form a recess in the flat of the action to correspond
with the aforesaid projecting base piece on the barrel. As applied to a double
barrel gun the base piece is formed with a hole through from end to end at each
side of the lumps; above the level of these holes and between the two is the normal
hole for the loose pin worked by the ordinary extractor stud for the purpose of
pushing the extractor out a short distance before the extractor springs are released
and begin their action. Between the two lumps I form a recess across down to
the flat of the barrel and fit a bridge piece therein which is fixed by means of a
screw, the end of which fits in a longitudinal slot in the aforesaid loose pin and
thus limits its stroke. The end of the barrel is recessed for the heads of the
extractor legs leaving a piece at top and bottom for guiding or steadying the said
heads. These legs are recessed for a suitable length and this recessed part works
against the aforesaid bridge piece, so that their rearward motion is limited thereby.
From the back of the head of the action and on each side of the bolt I drill a hole
through the whole length of the body and coming out just below the body pin.
In these holes I fit pins or legs which by coil spring are pulled back. When the
bammer is at full cock the fore ends of the pins are flush with the rounded end of
the body and their rear ends project a short distance at the rear of the body. The
tumblers are so formed that when the hammer is let down the tumblers push the
said pins forward so as to project a short distance at the fore end.
The pulling joint is fitted in the usual manner, the strap of the fore end however
being made broad. Through the hollow of the joint I fit two cams which work in
fulcruins and are actuated by two flat springs. These latter are attached at their

page_text: front end to the underside of the strap by screws or otherwise their rear ends being
fitted with friction rollers which work against the cams, the underside of the latter
being formed with half round recess for the aforesaid friction rollers to drop into
and thus hold the springs fast when extended or bent.
In firing the gun the tumblers push the pins forward as stated and when opening
the gun the projecting pins press against the underside of the cams and release
the springs therefrom. The cams then strike the fore ends of the legs of the
extractors and suddenly eject the cartridges.
When the gun is opened and the hammers at full cock the loose pin pushes the
extractors rearward far enough to enable the cartridges to be removed by the hand
in the usual manner.
COMPLETE SPECIFICATION..
Improvements in Breech-loading Breakdown Sporting Guns
and Rifles.
I GEORGE JEFFRIES of Norwich in the County of Norfolk, Gun Maker 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 improvements relate mainly to improved means for ejecting the spent
cartridges and as regards a double barrelled fire arm ejecting them singly or
together.
I
And in order that my invention may be fully understood and readily carried
into effect I will now describe the same with reference to the accompanying
drawings in which I have shewn the invention applied to a double barrelled
sporting fire arm.
Figure 1 is a side view of the part of the fire arm in question.
Figure 2 is a plan of underside of barrel shewing one extractor in the in position
and the other in the out position.
Figure 3 is a plan of the body.

Figure 4 is an end view of the breech end of the barrel shewing the extractors
in their places and Figure 44 a cross section on line C. D. Figure 2.
Figure 5 cross section of the body on line A. B.
Figure 6 is a plan view of the falling joint and strap, Figure 7 a plan of
underside of same, Figure 8 an end view and Figure a longitudinal section and

page_text: shewing also the extractors, one of them being in the position ready for action and
the other in the position after action.
Figure 10 is a perspective view of the extractors removed from the gun.
Figure 11 a perspective view of the cam for actuating the extractors and
Figure 12 a side view of the loose pin which works the extractors before the
extractor springs come into action.
The lumps aa¹ are brazed onto the barrel in the usual manner. The said lumps
are made with a broad base pièce b which stands up above (or rather beyond the
underside of) the barrel at each side of the lump or lumps as shewn especially in
Figures 2. 3. 4 and 5. I form. a recess c in the flat of the action or upper part of
the body, see Figures 3 and 5, to correspond with the aforesaid projecting base
piece b on the barrel and leaving a rib or flange c¹ standing up on each side of such
recess c. As applied to a double barrelled gun, as here shewn, the base piece b is
formed with a longitudinal hole through from end to end at each side of the
lumps a. a¹ as best seen at d d in Figure 4. Above the level of these holes d and
between the two is the usual hole e for the loose pin d¹ which is shewn separately
in Figure 12 and is worked by the ordinary extractor stud f, see especially
Figures 3 and 5, for the purpose of pushing the extractors (or extractor) out a
short distance before the extractor springs are released and begin their action.
Between the two lumps a. a¹ I form a recess across down to the flat of the
barrels, see Figures 2 and 44, and fit a bridge piece g..therein which is fixed by
means of a screw g¹ the end of which fits in a longitudinal recess d² or slot in the
aforesaid loose pin d and thus limits its stroke. The end of the barrel is recessed
as shewn in Figure 2 for the beads h of the extractor legs h' (the extractors are
shewn separately in Figure 10) leaving a piece i at top, Figures 1. 2 and 4, for
steadying the said heads h, the piece having parallel grooves into which the
upper ends of the extractor heads work. The legs are as shewn in Figures 9
and 10 recessed at h³ for a considerable length and this recessed part works against
the aforesaid bridge g so that the rearward motion of the extractors is limited
thereby.
From the back of the head of the action and on each side of the falling joint bolt
or fulcrum pink I drill a hole through the whole length of the body and coming
out just below the body fulcruin pin k, see Figures 1 and 5. In these holes I fit
pins or legs which by coil springs m are pulled back. When the hammer is at
full cock the fore end of the pins are flush with the fore end of the body, see
Figure 1, and their rear ends project a short distance at the rear of the body.
The tumblers n are each so formed that when the hammer is let down the
tumbler pushes the said pin forward so as to cause it to project a short distance
at the fore end.
The falling joint Figures 1. 6. 7. 8 and 9 is fitted in the usual manner, the strap o
at the fore end of the body however being made broad. Through the hollow of
the joint I fit two cams p, Figures 1. 6. 7. 9 and 11; which work on fulcrums p¹.
and are actuated by two flat springs q. In Figure 9 the front spring is in tension
and the back spring in the spent position of the weapon. These flat springs q are
attached at their front end to the underside of the strap o by screws q', or otherwise,
their rear end being fitted with friction rollers q' which work against the cams P,
the underside of the latter being formed with half round recess 2 for the aforesaid
friction roller q² to drop into and thus hold the spring q fast when extended or
bent.
In firing the gun the tumbler or tumblers n push the pins or one of them
forward as stated and when opening the gun the projecting pin or pins / press
against the underside of the cams p and release the springs q or one of them there-
from. The cam or cams then strike the fore ends of the legs of the extractors
and suddenly eject the cartridge or cartridges.
When the gun is opened and the hammers at full cock the loose pin d pushes
the extractors rearward far enough to enable the cartridges to be removed by the
hand in the usual manner.

page_text: 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 :-
First Fitting the lumps a a¹ with a broad base piece b which fits in a recess c
between two flanges c¹ c¹ and is deep enough to afford room for the extractor leg
holes to be formed there through substantially as set forth.
Second Constructing the extractors separately and each extractor having a leg
working in its hole for the purpose of their being actuated separatively if desired
substantially as set forth.
Third-The bridge piece g with screw g¹ for fixing it and for limiting the stroke
of the loose pin d¹, the said bridge piece serving also to limit the stroke of the
extractor legs substantially as set forth.
Fourth The cams p working in slots in the falling joint'o, in combination with
the flat springs q provided with friction rollers q' substantially as set forth,
Fifth The ordinary extractor stud f on the body in combination with the loose
pin d¹ for the purpose of impelling the cartridge extractors a short distance before
the spring or springs q are released substantially as set forth.
Sixth The improved construction of breakdown sporting gun substantially as
described, and as shewn on the drawings,
