We, HENRY WILLIAM HOLLAND of 98 New Bond Street, London, Gun Maker,
and JOHN ROBERTSON of 4 Dansey Yard, Wardour Street, London, Gun Maker, do
hereby declare the nature of this invention to be as follows:-
The improvements relate to that class of extractor mechanism in which the cases of
exploded cartridges are ejected from the barrels whenever the barrels are turned down
to open the breech.
When the gun is opened both cartridge cases (in a double barrelled gun) are first
withdrawn as usual a short distance by the ordinary extractor mechanism and after-
wards if one or other of the cartridges has been previously fired the empty cartridge
case is ejected by a rod forced against it by the action of a coiled spring.
According to our invention we place this rod in a line with the stem of the extractor
and above the top of the plate which forms the fore end of the hinge joint and which
is secured to the under side of the barrels as usual. We couple the above mentioned
rod to a slide which passes through a slot in the plate and which is acted on by a
coiled spring on the under side of the plate. Preferably the spring is made to
surround a rod which extends forwards from the slide parallel with the first mentioned
rod. Each time that the gun is closed the slide is forced back against the action of
the spring by the extractor being forced back in the ordinary way by the breech
plate a sear at the side of the fore plate then catches and holds the slide back.
The sear nose acts with a notch or bent on the underside of the slide whilst the
other end of the sear lever extends backwards towards the pin of the joint upon
which the barrels turn. Opposite to this end of the lever the joint pin has around it
a loose collar and on the collar is a small projection.

page_text: A lover also is made to engage with the collar and to extend back to the sear of
the lock or safety sear so that it may be acted on by this sear in such manner that if
the lock is at full cock or the trigger has not been pulled the projection on the collar
is turned into such a position that the end of the sear lever carried as above mentioned
by the fore plate does not strike against it when the breech is opened but if the
trigger has been pulled and the cartridge has been fired then the collar is turned and
the projection upon it is brought into such a position that tho sear lever strikes
against it as the breech is opened and the slide thereby set free and allowed to be
thrown quickly forward by the coiled spring so causing the exploded cartridge case
to be ejected.

Improvements in Extractor Mechanism for Drop Down Small
Arms.
We, HENRY WILLIAM HOLLAND of 98 New Bond Street, London, Gun Maker,
and JOHN ROBERTSON of 4 Dansey Yard, Wardour Street, London, 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:
The improvements relate to that class of extractor mechanism in which the cases
of exploded cartridges are ejected from the barrels whenever the barrels are turned
down to open the breech.
When the gun is opened both cartridge cases (in a double barrelled gun) are first
withdrawn as usual a short distance by the ordinary extractor mechanism and after-
wards if one or other of the cartridges has been previously fired the empty cartridge
case is ejected by a rod forced against it by the action of a coiled spring.
According to our invention we place this rod in a line with the stem of the extractor
and above the top of the plate which forms the fore end of the hinge joint and which
is secured to the under side of the barrels as usual. We make the above mentioned
rod to form part of a slide which passes through a slot in the plate and which is
acted on by a coiled spring on the under side of the plate. Preferably the spring is
made to surround a rod which extends forwards from the slide parallel with the first
mentioned ro. Each time that the gun is closed the slide is forced back against the
action of the spring by the extractor being forced back in the ordinary way by the
breech plate a sear at the side of the fore plate then caiches and holds the slide
back. The sear nose acts with a notch or bent on the underside of the slide-whilst
the other end of the sear lever extends backwards towards the pin of the joint upon
which the barrels turn.
Turning upon the joint pin or it may be on a pin in rear of the joint pin is a lever
one arm of which extends forwards. If the hammer has not fallen the end of this
lever arm is either in such a position that the end of the sear lever carried as above
mentioned by the fore plate does not strike against it when the breech is opened or
else if it does strike against it the lever is free to yield and not trip the sear-but if
the trigger has been pulled and the cartridge has been fired then the end of the lever
is brought into or held in such a position that the sear lever striking against it as
the breech is opened is tripped and the slide set free and allowed to be thrown
quickly forward by the coiled spring so causing the exploded cartridge caso to be
ejected.
.
The drawings hereunto annexed shew examples of extractor mechanism for drop
down small arms constructed in the above manner.
Figure 1 is a longitudinal section through the breech end of the barrels and body
shewing one of the locks of a double barrelled gun.

page_text: .
Figures 2, 3 and 4 are similar views with the mechanisin used for cocking the
hammer removed in order that the action of the parts for ejecting an empty cartridge
case may be better seen.
Figure 2 shews the barrels closed and the hammer fallen. Figure 3 shows the
position of the parts when the barrels have been almost but not completely dropped.
Figure 4 shows the position of the parts when the barrels have been similarly dropped
when the hammer has not previously fallen.
A is the extractor, a separate one being used for each barrel as in other guns of
this class. The stem of the extractor extends back beyond the joint pin B and when
the barrels are turned down is acted upon by a cain piece on the body in the ordinary
manner and the extractor caused to partially withdraw the cartridge a short distance
as shown at Figure 4-C is a slide capable of moving to and fro in a longitudinal
slot in the fore end D. Part of this slide is above the fore end and part below it.
The portion above comes in front of the end of the extractor stem; the portion below
is pressed backwards by a rod E acted upon by a coiled spring F. On the underside
of the slide is a notch or bent into which the sear G catches each time that the slide
is forced forwards by the extractor stem whenever the barrels are closed-H is a
spring acting upon the sear.
A side elevation and underside view of the strap or fore end D with the sear and
its spring for the ejector mechanism for one barrel are shewn at Figures 5-a side
elevation and plan of one slide Care shown at Figures 6-and side elevation and
plan of one rod E and its spring are shown at Figures 7.
I is a lever turning upon the joint pin B one arm of this lever extends forwards
in front of the joint pin and passes through a slot D¹ in the strap or fore end D-its
other arm is jointed to the fore arm of a lever J the fulcrum pin of which is carried
by the body piece or action. The rear arm of this lover comes above the tail end of
the sear K of the lock and when the trigger is pulled it is slightly raised by the tail
end of the scar-the lever I is thereby also turned a distance and its fore arm brought
into such a position that when the barrels are turned down the tail end of the sear G
comes against it and this it does just before the hammer has been completely put
back to its cocked position and when the sear K. has not yet fallen into the notch in
the hammer. The tail end of the lever J is consequently still upheld by the tail of
the sear K and as it cannot yield the sear G is tripped and the slide (liberated.
The coiled spring then throws the slide backwards against the extractor stem and
causes the extractor to eject the cartridge case. The remainder of the turning down
movement of the barrels completes the setting-back of the hammer to its cocked
position shown by dotted lines in figure 3.
If however the trigger has not been pulled before the barrels are turned down the
fore end of the lever I will not have been moved into a position for the tail end of
the sear G to strike against it and consequently the slide will not be liberated and the
cartridge will remain in the barrel.
Each time that the barrels are closed the extractors are pressed forwards by the
back plate of the body in the ordinary manner-this presses back the slides C which
are then caught by the sears G. L is a safety scar or lever of ordinary construction.
A modification of the above construction is shewn at figures 8 and 9.
Figure 8 shews the barrels closed and the hammer fallen, and figure 9 shews the
barrels partially but not completely turned down after the hainmer has so fallen.
The parts are marked with the same letters of reference as in the preceding
figures.
In this modification the lever J is dono away with and the tail end of the lever I
is prolonged so that it comes alongside of the hammer of the lock and on the side of
the hammer is a projection N in such a position that the end of the lever cannot
strike against it if the hammer is cocked but can strike against it if the hammer
has fallen.
The action is as follows
:-
When the barrels are turned down the tail end of the sear G comes against the
L

page_text: fallen the lever can turn freely and the sear G is not tripped and the cartridge is not
ejected but if the trigger has been pulled and the hammer has fallen then when
the tail end of the sear G comes against the fore end of the lever I it turns this lever
until its tail end comes against the projection N on the hammer and the lever being
thereby prevented from turning the scar G is tripped and the slide C thrown back-
wards by the coiled spring and the empty cartridge case is ejected. On the
completion of the turning-down movement of the barrels the setting back of the
hammer to its cocked position shown by dotted lines in figure 9 is completed. When
a fresh cartridge has been put into the barrel and the barrels again closed the lever I
is brought back into the position shewn at figures 8.
Figures 10 and 11 shew a modification of the above arrangement in which the
lever I instead of turning upon the joint pin turns upon a pin in rear thereof and a
short joint pin is used extending only from the bottoin of the recess on one side of
the body in which the lever I lies to the similar recess on the opposite side of the
body.
The parts are marked with the same letters of reference as in the preceding figures
and the action is the same as in the modification shown at figures 8 and 9.
Figures 12 and 13 show a modification of the above arrangement which is not only
suitable for being used with hammerless guns but also with guns fitted with rebounding
locks and hammers.
In this modification the tail end of the lever I is struck by the hammer of the lock
or part moving with it whenever the hammer falls--and when so forced downwards
from the position shown by dotted lines in figure 12 it comes below and springs under
a projection M on the body piece or action. When the lever has been turned into
this position and the barrels are turned down the tail end of the sear G comes against
the forward end of the lever and the lever being hindered by the stop M from turning
freely the sear G is tripped and the cartridge case ejected. When this has taken
place the strap or fore body D comes against the top of the front end of the lever
and the further turning-down movement of the barrels turns the lever back to its
original position as shown by dotted lines in figures 12 and 13, the lever being
sprung past the stop M and retained in the position into which it is then turned
by reason of its being made of spring material and bearing against the end of the
stop.
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. The combination of ejector mechanism for drop down guns substantially in the
manner herein before described and illustrated in the drawings annexed.
2. The combination with a drop down gun of a lever which if the hammer of the
lock has fallen is turned into or retained in such a position that on the turning down
of the barrels a sear carried by the fore end comes against and is tripped by it and a
spring thereby allowed to act upon the extractor and throw out the empty cartridge
case whilst if the hammer has not fallen the lever is not so retained or the sear tripped
or the cartridge ejected.
3. In combination with the fore end D a slide C projecting partly above the fore
end to act upon the extractor stem and partly below to be acted upon by a coiled
spring and having in it a notch or bent for a sear carried by the fore end to catch
into substantially as described which sear when the barrels are opened is tripped if the
hammer has fallen but is not tripped if the hammer has not fallen.
