Improvements in the Ejector Mechanism of Drop Down
Small Arms.
I CHARLES HENRY MALEHAM of No. 5 Westbar, Sheffield in the County of
York, Gun Maker do hereby declare the nature of this invention to be as
follows:-
My invention consists of the following improvements in or additions to certain
kinds of the ejector mechanisms of drop down small arms, the object of my said
improvements or additions being to facilitate the closing of the gun or small arm.
My invention has reference to those kinds of ejector mechanisms of drop down
small arms in which the ejection of the cartridge case from the barrel, on the
opening of the gun is effected by the action of an ejector hammer or vertical arm
upon the end of the rod or leg of the extractor, the said ejector haminer being
released by the taking out of bent of a sear by means of mechanism brought into
action on the opening of the gun.
The ejector hammer is operated by a V or doubled spring resembling a main
spring. In the ordinary arrangement the expanded spring of the ejector hammer
is fully compressed on the closing of the gun.
My invention consists principally in adding to or combining with ejector
mechanisms of the kinds described of a lever so constructed, and arranged and
acted upon by the joint end of the body, that on the opening and closing of the
gun the said lever is made to act upon the lower limb of the ejector hammer spring
and either raise and fully compress the spring or permit the said limb to take its
expanded position.
The lever which I use turns upon the same centre as the ejector hammer. Its
rear arm extends to the joint end of the body and bears against a flat abutment
or cut away part at the said joint end, and the end of the fore arm of the
lever which end is inclined on its upper side, is situated under and supports the
lower limb of the ejector hammer spring. The lower limb of the ejector hammer
spring is free instead of being fixed to the box or case in which it is situated
as usual. The said lower free limb of the spring is thus made capable of being
raised and the spring fully compressed or permitted to take its expanded
position.
When the gun is opened to extract and eject the empty cartridge case, the
action of the Hat abutment at the joint end of the body upon the rear arm of
the lever causes its fore arm to rise and lift the lower limb of the spring
and bring the said spring into its fully compressed state ready on the release of
the ejector hammer to cause the latter to act upon the extractor leg and eject the
cartridge case as is well understood.
When the gun is closed the fore arm of the lever descends, followed by the free
lower limb of the ejector hammer spring, which limb takes its expanded position,
the upper limb of the spring being at the same time partly compressed by the
cocking of the ejector hammer.
Thus, the compressing of the ejector hammer spring is effected partly by the
opening and partly by the closing of the gun instead of fully compressing the
spring by the closing of the gun as usual.. Hence the closing of the gun is
facilitated.

Improvements in the Ejector Mechanism of Drop Down
Small Arms.
I CHARLES HENRY MALEHAM of No. 5 Westbar, Sheffield, in the County of
York, Gun Maker, do hereby declare the nature of my invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :—
My invention consists of the following improvements in or additions to certain
kinds of the ejector mechanisms of drop down small arms, the object of my said
improvements or additions being to facilitate the closing of the gun or
small arm.
My invention has reference to those kinds of ejector mechanisms of drop
down small arms in which the ejection of the cartridge case from the barrel
on the opening of the gun is effected by the action of an ejector hammer or
vertical arm upon the end of the rod or leg of the extractor, the said ejector
hammer being released by the taking out of bent of a sear by means of
mechanism brought into action on the opening of the gun. The ejector hammer
is operated by a V or doubled spring resembling a main spring. In the ordinary
arrangement the expanded spring of the ejector hammer is fully compressed on
the closing of the gun.
My invention consists principally in adding to or combining with ejector
mechanisms of the kind described of a lever so constructed and arranged and acted
upon by the joint end of the body that on the opening and closing of the gun
the said lever is made to act upon the lower limb of the ejector hammer spring
and either raise and fully compress the spring or permit the said limb to take
its expanded position.
The lever which I use turns upon the same centre as the ejector hammer.
Its rear
arm extends to the joint end of the body and bears against a flat
abutment or cut away part at the said joint end, and the end of the fore arm
of the lever, which end is inclined on its upper side, is situated under and supports
the lower limb of the ejector hammer spring.
The lower limb of the ejector hammer spring is free instead of being fixed to
the box or case in which it is situated as usual. The said lower free limb of the
spring is thus made capable of being raised and the spring fully compressed or
permitted to take its expanded position.
When the gun is opened to extract and eject the empty cartridge case, the
action of the Hat abutment at the joint end of the body upon the rear arm of the
lever causes its fore arm to rise and lift the lower limb of the spring and bring
the said spring into its fully compressed state ready on the release of the ejector
hammer to cause the latter to act upon the extractor leg and eject the cartridge
case as is well understood.
When the gun is closed, the fore arm of the lever descends, followed by the free
lower limb of the ejector hammer spring, which limb takes its expanded position,
the upper limb of the spring being at the same time partly compressed by the
cocking of the ejector hammer.
Thus, the compressing of the ejector hammer spring is effected partly by the
opening and partly by the closing of the gun instead of fully compressing the
spring by the closing of the gun as usual. Hence, the closing of the gun is
facilitated.
I will now describe with reference to the accompanying drawing the manner in
which my invention is to be performed.
Figures 1, 2 and 3 represent in longitudinal vertical section, the breech end of
a double barrel drop down gun containing mechanism constructed and arranged
according to my invention for compressing the ejector hammer spring of

page_text: the ejector mechanism on the opening of the gun for ejecting the spent
cartridge case.
In Figure 1 the barrels are represented shut down and the cock discharged, the
ejector hammer spring being in its partly compressed condition.
In Figure 2 the gun is represented opened nearly to its full extent and the
ejector hammer spring in its fully compressed state, the ejector hammer being
about to be released by the releasing mechanism of the gun and in Figure 3, the
gun is represented fully opened and the rod or leg of the extractor projected
outwards for ejecting the spent cartridge case, by the action of the ejector hammer,
the spring of the said ejector hammer being in its fully expanded state.
The same letters of reference indicate the same parts in the several figures of
the drawing.
a, a are the barrels of the gun and the break off; is the cock or hammer,
cocked by the opening of the gun through the action of the fore end of the gun
upon the dog or lever d as usual; e is the sliding main spring of the hammer c;
fis the leg or rod of the extractor fork and g is the ejector hammer which when
discharged gives a sharp blow to the said extractor leg or rod for ejecting the
spent cartridge case as is well understood; is the V or doubled spring of the
ejector hammer the lower limb of which is free instead of being fixed to the box
or case on the fore end as usual. The ejector hammer is held in its cocked
position by the sear lever i taking into a bent in the said ejector hammer, the
said sear lever being put into bent by the advance of the sliding main spring e
(see Figure 1) on the fall of the hammer c to discharge the gun, the said sliding
main springe being provided at its bent end with a projection which, operates
upon the said sear lever; and the ejector hammer is released on opening the gun
by the projection on the body m striking against the tail end of the sear
lever i and taking it out of bent with the ejector hammer. The mechanism for
putting the sear lever into bent and for releasing the ejector hammer g constitute
no part of my invention and other mechanism than that represented may be
employed for those purposes.
The lever for compressing the ejector hammer spring is marked k, k² and turns
on the same centre 7 as the ejector hammer y. The rear arm ² of the spring
compressing lever jointed to the fore arm k of the said lever, the said jointed
rear arm, extending to the joint end of the body m and bearing against a flat
abutment or cut away part n at the joint end of the body. The fore arm k of
the spring compressing lever kk is inclined on its upper side and is situated
under and supports the lower free limb of the ejector hammer spring has
represented. By this arrangement the lower free limb of the ejector hammer
spring is made capable of being raised to the upper limb and the spring fully
compressed as represented in Figure 2, or permitted to take its expanded
position as represented in Figure 1 ready to be compressed on the opening
of the gun.
When the parts of the gun are in the respective positions represented in
Figure 1 the opening of the gun causes the ejector hammer to be discharged and
its spring compressed. In the said Figure 1 it will be seen that the upper
limb of the ejector hammer spring has been compressed on the closing of the
gun by the action of the leg or rod f of the extractor upon the ejector hammer g
and the sliding main spring e has been brought, by the fall of the hammer c to
discharge the gun, into its operating position for putting the sear lever into bent
with the ejector hammer. When the gun is being opened as represented in
Figure 2, the action of the flat abutment n at the joint end of the body m upon
the jointed rear arm of the spring compressing lever k, k³ causes the fore arm k
of the said lever to rise and lift the lower limb of the said spring towards the upper
limb and bring the said spring into its fully compressed state. On the gun being
fully opened the ejector hammer g is released and the compressed spring acting
upon it causes it to strike the extractor leg or rod f a sharp blow and eject the
spent cartridge case as represented in Figure 3, where the spring of the ejector

page_text: hammer, after it has operated the said hammer, is represented in its fully
expanded state.
On closing the gun the fore arm of the spring compressing lever takes the
position represented in Figure 1 and the lower limb of the spring travels upon the
said fore arm & and takes its expanded position, the upper limb of the said spring
being at the same time partly compressed by the cocking of the ejector hammer as
seen in Figure 1.
The principal compressing of the ejector hammer spring being thus effected by
the opening of the gun, the closing of the gun is much facilitated.
Having now particularly described and ascertained the nature of my inven-
tion and the manner in which the same is to be performed I declare that I
claim as m
my invention of "Improvements in the ejector mechanism of drop down
small arms
-:
The addition to or combination with ejector mechanism of the kinds described,
of a lever for supporting the free lower limb of the ejector hammer spring, the
rear jointed arm of the said lever being so operated upon, on the opening of the
gun or small arm, by the joint end of the body of the said gun or small arm that
the fore arm of the said ejector spring lever lifts the lower limb of the spring
nearly into contact with the upper limb and brings the said spring into its fully
compressed state for discharging the ejector hammer, the several parts being
constructed, arranged and operating for the purpose and substantially as herein-
before described and illustrated in the accompanying drawing.
