We FREDERICK JAMES PENN of Frederick Villa Linwood Road Handsworth in
the County of Stafford Gun Action Maker and JOHN DEELEY the elder of No. 82 High
Street Birmingham in the County of Warwick Gun Manufacturer do hereby declare
the nature of this Invention to be as follows:-
Our invention has reference to the extracting or ejecting mechanism of drop down
guns of the kind described represented and claimed in the specifications of patents
granted to John Deeley the younger dated respectively the 3rd November 1884
No. 14526 and March 26th 1886 No. 4289 of which patents one of us namely
John Deeley the elder is the proprietor.
Our said invention consists in the modifications hereinafter described in the said
patent mechanism.
We will describe our invention in connection with a drop down gun.
At the bend or turn of the main spring of the gun we make a projection or
prolongation which projection or prolongation we make to engage directly with the
sear like lever by which the ejector hammer is held back. By making the projection
or prolongation of the main spring engage directly with the said sear like lever
instead of through the intervention of the slide represented and described in the
patents herein before referred to the mechanism is simplified and the liability to
derangement reduced.
When the breech end of the barrel is raised for charging the gun the hammer is
cocked by the sear engaging in the bent of the said hammer or its tumbler and the
main spring is drawn back. When the hammer falls on the discharge of the gun
the projection or prolongation of the main spring advances under the tail end of the
sear like lever. On again lifting the breech end of the barrel for recharging the nose
of the sear like lever is depressed by the projection or prolongation of the mainspring
arresting the motion of the tail end of the said lever. The said lever is disengaged
from the ejector hammer which then falls and ejects the case of the discharged
cartridge.

page_text: The lower end of the tail of the sear like lever may be made to project into a slot
in the joint end of the body of the gun by the action of the mainspring when the
breech end of the barrel is shut down after charging. The slot in the body of the gun
has a shoulder which when the breech end of the barrel is fully raised comes against
the lower or projecting part of the tail of the sear like lever thereby disengaging the
nose of the said lever from the ejector hammer which falling ejects the case of the
exploded cartridge.
Our improvements are applicable both to single and double barrel drop down guns
and other small arms.
COMPLETE SPECIFICATION.
Improvements in the Extracting or Ejecting Mechanism of Drop
Down Small Arms.
We FREDERICK JAMES PENN of Frederick Villa, Linwood Road Handsworth in the
County of Stafford, Gun Action Maker and JOHN DEELEY the elder of No. 82 High
Street Birmingham in the County of Warwick, Gun Manufacturer, do hereby declare
the nature of our invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
1
Our invention has reference to the extracting or ejecting mechanism of drop down
guns of the kind described represented and claimed in the specifications of Patents
granted to John Deeley the younger dated respectively the 3rd November 1884
No. 11526 and March 26th 1886, No. 4289 of which patents one of us namely
John Deeley the elder is the proprietor.
Our said invention consists in the modifications hereinafter described in the said
patent mechanism.
We will describe our invention in connection with a drop down gun.
At the hend or turn of the mainspring of the gun we make a projection or pro-
longation which projection or prolongation we make to engage directly with the sear
like lever by which the ejector hammer is held back. By making the projection or
prolongation of the main spring engage directly with the said sear like lever instead
of through the intervention of the slide represented and described in the patents
herein before referred to the mechanism is simplified and the liability to derangement
reduced.

page_text: When the breech end of the barrel is raised for charging the gun the hammer is
cocked by the sear engaging in the bent of the said hammer or its tumbler and the
main spring is drawn back. When the hammer falls on the discharge of the gun the
projection or prolongation of the main spring advances under the tail end of the sear
like lever. On again lifting the breech end of the barrel for recharging, the nose of
the sear like lever is depressed by the projection or prolongation of the mainspring
arresting the motion of the tail end of the said lever. The said lever is disengaged
from the ejector hammer which then falls and ejects the case of the discharged
cartridge.
The lower end of the tail of the sear like lever may be made to project into a slot
in the joint end of the body of the gun by the action of the mainspring when the
breech end of the barrel is shut down after charging. The slot in the body of the gun
has a shoulder which when the breech end of the barrel is fully raised comes against
the lower or projecting part of the tail of the sear like lever thereby disengaging the
nose of the said lever from the ejector hammer which falling ejects the case of the
exploded cartridge.
Our improvements are applicable hoth to single and double barrel drop down guns
and other small arms.
Figures 1 and 2 of the accompanying Drawings represent in longitudinal section
the breech end of a drop down gun containing extracting or ejecting mechanism
constructed according to our invention. In Figure 1 the barrel is represented shut
down, the ejector hammer or hammer like arm in its cocked position and the ordinary
hammer in its fallen position; and in Figure 2 the breech end of the barrel is repre-
sented raised from the face of the break off, the ejecting hammer in. its discharged
position and the spent cartridge case ejected from the barrel and the ordinary hammer
cocked.
Figures 3 and 4 represent a modified arrangement of our invention.
The same letters of reference indicate the same parts in the several Figures of the
Drawings.
We will first describe the arrangement represented in Figures 1 and 2.
a is the main spring of the lock mechanisin the said spring being supported by and
working in guides in the body of the gun and 6 is the hammer which is cocked by
the raising of the breech end of the barrel for re-charging; c is the projection or
prolongation at the bend or turn of the main spring a the said projection or pro-
longation engaging directly with the tail end or upper arm of the sear like
lever d d by which the ejector hammer is held in its cocked position and released for
ejecting the spent cartridge case. The projection c of the main spring is curved
downwards and has a shoulder at bottom is the spring of the ejector hammer e;
y is the extractor rod and h the hook of the saine of the ordinary kind. The ejector
hammer e acts upon the front end of the extractor rod g and gives the ejecting motion
to the extractor the said ejector hammer being forced towards the break off when at
liberty to move by its spring f. The ejector hammer e is cocked on closing the breech
of the barrel by the action of the extractor rod upon its upper end the said hammer e
being held in its cocked position by the lower arm d of the sear like lever d &
engaging with the bent or projection on the said hammer e as seen in Figure 1.
When the hammer 6 falls on the discharge of the gun the main spring a is moved
forward and its projection or prolongation c is advanced under the tail end or upper
arm of the sear like lever d d² as represented in Figure 1 so that on lifting the
breech end of the barrel for recharging the gun, the nose or lower arm d of the sear
leverd, is depressed by the projection or prolongation c of the main spring acting
as a stop arresting the motion of the tail end d² of the sear lever d d. The nose of
the sear lever is thereby disengaged from the ejector hammer e which hammer falls
and acting upon the extractor rod g ejects the case of the exploded cartridge from the
barrel by means of the hook as illustrated in Figure 2.
So long as the hammer bis in the cocked position represented in Figure 2 the
main spring a remains in its withdrawn position and the projection or prolongation c
of the said main spring is out of the range of motion of the sear like lever engaged

page_text: with the ejector hammer and cannot cause the discharge of the ejector mechanism ;
hence the barrel of the gun may be raised any number of times without ejecting the
unexploded cartridge from the said barrel.
Although we prefer to combine with our invention ejecting mechanism consisting
of a hammer like arm and a sear like lever as described and represented yet we do
not limit ourselves to that kind of ejecting mechanism as the projection or prolonga
tion of the main spring acting as a stop may be used for releasing the holding sear or
an equivalent part of other ejecting mechanism. For example the ejecting mechanism
may consist of a spring bolt or rod acting upon the extractor or ejector rod the said
spring bolt or rod being held in a state of tension by a sear as described in the
specification of the patent granted to John Deeley the younger No. 14526 year 1884
the said sear being released on the opening of the gun by the projection or extension c
of the main spring a (when the latter is in its advanced position) acting directly or
indirectly upon the holding sear or equivalent part of the ejecting inechanism.
We will now describe the modified arrangement represented in Figures 3 and 4,
Figure 3 representing the barrel shut down the hammer fallen, the ejecting mechanism
in its cocked position and the lower branch of the tail of the sear lever projected into
the body of the gun and Figure 4 representing the breech end of the barrel raised,
the hammer cocked and the ejecting mechanism discharged for ejecting the spent
cartridge case from the barrel.
In this modification the projection or prolongation marked c² of the main spring a
has the form represented instead of being curved downwards as in the first described
arrangement and the upper arm or nose d² of the sear dis branched for the purpose
hereinafter described. In the body of the gun is a shoulder for releasing the sear on
the opening of the gun. The other parts are the same as in the first described
arrangement and corresponding parts are marked with the same letters of reference.
The funcion of the projection or prolongation c² of the main spring a is, when the
said spring has been moved into its forward position Figure 3 and the barrel is shut
down after charging, to act as a stop for the upper branch of the tail part d² of the
sear lever to bear against, during the cocking of the ejector hammer e by the
extractor rod y. By the striking of the upper branch of the tail end d² of the sear
lever against the projection of the main spring, as the barrel is shut down, the said
upper branch is raised and the lower branch made to project through the slot in the
joint part of the "fore end" and slightly enter the body of the gun and lie over the
shoulder in the said body of the gun. The sear lever when in this position is partly
disengaged from the bent or projection of the cocked ejector hammer e as represented
in Figure 3.
The parts being in the positions represented in Figure 3, that is, the hammer having
been discharged and the ejecting mechanism cocked the raising of the breech end of
the barrel causes the lower branch of the tail d² of the sear lever to strike against the
fixed shoulder on the body which shoulder acting as a stop turns the said sear lever
on its joint and disengages the nose of the said sear lever from the ejector hammer e
which falling ejects the spent cartridge case from the barrel in the inanner herein-
before described. So long as the hammer bis in its cocked position Figure 4 the
projection of the main spring is inoperative and does not on the opening of the gun
project the upper branch of the sear tail into the body of the gun, hence the lifting of
the breech end of the barrel when the hammer is in its cocked position cannot eject an
unexploded cartridge from the barrel.
Having now particularly described and ascertained the nature of our inven-
tion and the manner in which the same is to be performed we declare that we
claim as our invention of "Improvements in the extracting or ejecting mechanism
of drop down small arms":-
First The combination with or addition to the main spring of the gun or small
arm of a projection or prolongation at the bend or turn of the said spring which.

being used for projecting the tail end of the sear lever (or its equivalent) into the
body of the gun when the breech end of the barrel is shut down and the said shoulder
on the body being used for acting upon the projecting tail end of the sear lever and
disengaging the sear lever from the ejecting mechanism on raising the breech end of
the barrel for charging substantially as herein before described and illustrated in.
