Improvements in the Ejector Mechanism of Drop-down
Small-arms.
I WILLIAM HENRY BRIGHTON of No. 9 Whitehead Street Aston near Birminghau
in the County of Warwick Gun Action Filer do hereby declare the nature of this
Invention to be as follows:-
My invention consists of the construction and combination of parts hereinafter
described of the ejector mechanism of drop down small arms whereby the spring
kicker or ejector arm of the ejector mechanism is cocked or held in a state of
tension ready to be released on the opening of the small arm through the operation
of the cocking rod when the latter is advanced by the falling hammer on the
discharge of the small arm the kicker or ejector arm being inoperative until the.
small arm has been discharged.
My said invention consists further of the slide hereinafter described for causing
the spring kicker or ejector arm to be cocked or held in a state of tension while the
"fore end" is removed from the small arm. The spring kicker or ejector arm
which operates upon the leg or rod of the extractor to eject the exploded cartridge
case as well as the parts in connection with the said kicker are carried by the fore
end as usual. I use preferably a kicker or ejector arm consisting of a doubled blade
spring somewhat resembling an ordinary main spring but a sliding kicker forced
forward by a coiled spring may be used. Near the head of the spring kicker and
carried by the fore end is a horizontal sear or holding back lever one of the arms
of which is provided with a cross head and the other arm or tail passes to and
projects from the abutment or joint of the fore end bar. The sear or holding back
lever is taken out of action to release the spring kicker by the projecting tail end of
the sear or holding back lever coming against an incline on the end of the body of
the gun when the gun is opened. By turning aside the sear or holding back lever
the cross head of one of its arms can be brought in front of the spring kicker so
as to cock or hold it in a state of tension. The sear or holding back lever is
moved into the position last described by a vertical cranked lever having motion at.
right angles to that of the said sear or holding back lever. This cranked lever is
pivoted in the abutment of the fore end bar and its arms which are of different
lengths are situated on opposite sides of the said abutment. This lever is operated
upon by the outer end of the cocking rod working in the body of the gun.
the cocking rod is advanced by the falling hammer its outer end which is bevilled
acts against the short arm of the cranked lever turning the said lever on its joint
and the long arm of the said lever the side of which is bevilled acting against the
bevilled side of the sear or holding back turns the said sear or lever on its joint
and causes the cross head of one of its arms to project in front of and cock or hold
in a state of tension the spring kicker or ejector arm.
When
The action of the parts is as follows:-After the gun or small arm has been
discharged and reloaded the barrel is closed the act of closing the barrel causing,
the kicker or ejector arm to be forced back by the extractor rod or leg and put into
a compressed state but not held in that state in consequence of the position of the
sear or holding back lever the opening of the barrel before the gun is discharged
causing the unexploded cartridge to be partly extracted but not ejected.
On the discharge of the gun the cocking rod is advanced by the falling hammer
and its front end acting upon the cranked lever turns it upon its joint and causes its
longer arm to act upon and turn upon its joint the horizontal sear or holding, back
lever and bring its cross head in front of and cock or hold in a state of tension the
spring kicker or ejector arm. The ejector mechanisın is now in its operative state:

page_text: On opening the gun the projecting tail of the horizontal sear or holding back lever
comes against the incline described on the end of the body and thereby withdraws
the cross head of the said sear or holding back lever from the front of and releases the
spring kicker or ejector arm which by a sudden motion ejects the spent cartridge case
from the barrel. As the gun is opened to effect the ejecting operation the cocking rod
takes its back position removing its pressure from the cranked lever which being
thus free permits of the return motion of the holding back lever for releasing the
spring kicker or ejector arm.
My said invention is applicable to single and double barrel drop down guns or
small arms.
In order to readily withdraw the fore end containing the ejector mechanism from
the barrel it is necessary that the spring kicker or kickers should be held in a state
of tension. I effect this by means of a slide (forked in the case of a double gun)
working on the fore end bar the said slide being operated from the boss or head of
the hand lever by which the fore end is fastened to the barrel. The branches of the

the slide is advanced the bevilled ends of its branches act upon the horizontal sears
or holding back levers near their cross heads and cause the said heads to pass in
front of and hold back or cock the spring kickers or ejector arms.

Improvements in the Ejector Mechanism of Drop-down
Small-arms.
I WILLIAM HENRY BRIGHTON of No. 9 Whitehead Street, Aston near Birmingham
in the County of Warwick Gun Action Filer do hereby declare the nature of my
invention and the manner in which the same is to be performed to be particularly
described and ascertained in and by the following statement:-
My invention consists of the construction and combination of parts hereinafter
described of the ejector mechanism of drop down small arms, whereby the spring
kicker or ejector arm of the ejector mechanism is cocked or held in a state of tension
ready to be released on the opening of the small arm through the operation of the
cocking rod when the latter is advanced by the falling hammer on the discharge of
the small arm, the kicker or ejector arm being inoperative until the small arm has
been discharged.
My invention consists further of the slide hereinafter described for causing the
spring kicker or ejector arm to be cocked or held in a state of tension while the
"fore end" is removed from the small arm. The spring kicker or ejector arm
which operates upon the leg or rod of the extractor to eject the exploded cartridge
case as well as the parts in connection with the said kicker are carried by the fore end
as usual use a kicker or ejector arm consisting of a double blade spring some-
what resembling an ordinary mainspring, or I use a jointed kicker or a sliding kicker
forced forward by a coiied spring. Near the head of the spring kicker and
carried by the fore end is a horizontal sear or holding back lever one of the arms
of which is provided with a cross head and the other arm or tail passes to and
projects from the abutment or joint of the fore end bar. The sear or holding back
lever is taken out of action to release the spring kicker by the projecting tail end of
the sear or holding back lever coming against an incline on the end of the body
of the gun when the gun is opened. Or the holding back sear may be taken out
of action by a small rocking lever acted upon by the barrels when the gun is
opened.
By turning aside the sear or holding back lever the cross head of one of its arms
can be brought in front of the spring kicker so as to cock or hold it in a state of
:

page_text: tension. The sear or holding back lever is moved into the position last described
by a vertical cranked lever having motion at right angles to that of the said scar or
holding back lever. This cranked lever is pivotted in the abutment of the fore end
bar and its arms are situated on opposite sides of the said abutment. This lever is
operated upon by the outer end of the cocking rod working in the body of the gun.
When the cocking rod is advanced by the falling hammer its outer end which is
bevilled, acts against the short arm of the cranked lever turning the said lever on
its joint and the long arm of the said lever, the side of which is bevilled, acting
against the bevilled side of the sear or holding back lever turns the said sear or
lever on its joint and causes the cross head of one of its arms to project in front
of and cock or hold in a state of tension the spring kicker or ejector arm.
My invention is applicable to single and double barrel drop down guns or small
arms.
I will now describe with reference to the accompanying Drawing the manner in
which my invention is to be performed.
Figure 1 represents in longitudinal vertical section and Figure 2 in plan of under-
side (partly in horizontal section) the breech end of a double barrel drop down gun
containing ejecting mechanism constructed according to my invention, the kickers
or ejector arms of the said mechanism being represented cocked or held in a state of
tension by the advance of the sears or holding back levers which have been acted
upon by the cranked levers and cocking rods on the discharge of the gun; Figure 3
represents a portion of the ejector mechanism of the gun. in the positions which the
parts respectively occupy after the kicker or ejector arm has been forced back by the
extractor rod on closing the gun, but before the said kicker or ejector arm has been
held in its cocked position on the discharge of the gun, and Figure 4 represents
the parts of the ejector mechanism in the same positions as represented in Figure 1
but the parts which operate upon the sears or holding back levers are better exhibited:
Figure 5 represents the gun after the barrels have been lifted from the face of the
break off the holding back sears or levers having been withdrawn from the ejector
arms and the ejection of the empty cartridge cases effected: Figure 6 represents in
plan and end elevation one of the sears or holding back levers of the ejector arms
drawn to a larger scale and Figure 7 represents in side elevation and end elevation
one of the sears or holding back levers in conjunction with the sear releasing or
rocking lever drawn to a larger scale and Figure represents in side elevation
and end elevation one of the cranked levers drawn to a larger scale by which
the sear or holding down levers are operated through the action of the cocking
rods.
The same letters of reference indicate the same parts in Figures 1, 2, 3, 4, 5, (i, 7,
and 8.
As the construction and action of the parts of the ejector mechanism applied to both
barrels of the gun are alike I will for convenience of explanation describe only the
mechanism applied to one barrel.
a is the barrel of the gun and the body; c is the extractor rod and the hook
of the same; e is the jointed ejector arm or kicker and e² is the spring of the
same, the said ejector arm or kicker being contained in a box connected with the
fore end of the gun: h² is the horizontal sear or holding back lever turning on
the centre (shewn separately in Figure 6).
The horizontal sear or holding back lever has a cross head h² and near the cross
head a notch or shoulder & is made for engaging upon the horizontal shoulder at
the front of the ejector arm or kicker e. The cross head of the sear or holding
down lever is inclined at for the releasing or rocking lever p to act npon it and
the said sear or holding down lever is also bevilled or inclined at P for the upper
arm of the vertical cranked lever n, n² to operate upon. The vertical cranked
lever n, n² (shewn separately in Figure 8) turns on the centre m in the abutment
of the bar of the fore end and has motion at right angles to the said sear or
holding back lever. The end of the upper arm n of the cranked lever n, n² is
inclined at (see Figure 8) and acts upon the bevilled or inclined part of the

page_text: holding back lever to put the latter into action and upon the bottom of the lower
arm of the cranked lever n, n² the cocking rod of the gun operates. The small
releasing or rocking lever for withdrawing the sear or holding back lever on the
n² and
opening of the gun turns on the same centre or axis m as the cranked lever
the said lever has at back a projecting piece or stud p² which occupies and works
in a recess at between the barrels a, a. The front or head p³ of the releasing lever p
is inclined for acting upon and turning aside the sear or holding back lever for
releasing the ejector arm or kicker.
The action of the parts is as follows; After the gun or small arm has been
discharged and reloaded the barrel is closed or shut down the act of closing the
barrel causing the kicker or ejector arm e to be forced back by the extrator rod or
leg c and put into a compressed state but not held in that state in consequence of the
position of the sear or holding back lever h, h² as represented in Figure 3, the opening
of the barrel before the gun is discharged causing the unexploded cartridge to be
partly extracted but not ejected.
On the discharge of the gun the cocking rod is advanced by the falling hammer
and its front end acting upon the lower arm n² of the cranked lever n, n' turns it
upon its joint and causes its longer arm, n³ to act upon and turn upon its joint the
horizontal sear or holding back lever h, 2. The arm of the said sear carrying the
cross head 2 is thereby moved inwards and its shoulder k made to engage upon
the shoulder in front of the kicker or ejector arm e and cock or hold it in a state of
tension as represented in Figures 1, 2, and 4. The ejector mechanism is now in its
operative state, that is, realy to eject on the opening of the gun the spent cartridge
case. On opening the gun the bottom of the recess 7 between the barrels strikes
against the stud or tail piece of the releasing lever and turns the said lever on its
centre. The upper arm p³ having an inclined face is thereby depressed and the said
inclined face acting against the inclined end of the cross head 2 of the holding back
lever (see Figure 7) turns the said lever on its joint. The cross head arm of the
said lever is thereby moved outwards and its shoulder withdrawn from the
horizontal shoulder of the spring kicker or ejector arm e and releases it, which
kicker or ejector arm by a sudden motion ejects the spent cartridge case from the
barrel, the several parts now having the respective positions represented in Figure 5.
As the gun is opened to effect the ejecting operation, the cocking rod takes its back
position removing its pressure from the cranked lever n, which being thus free
permits of the return motion of the holding back lever h, 2 for releasing the
spring kicker or ejector. arm e as hereinbefore described and represented in
Figure 5.
Figure 9 represents in longitudinal section ejector mechanism constructed
according to my invention in which a blade spring kicker or ejector arm is used
instead of a jointed ejector arm and the horizontal sear or holding back lever is
withdrawn from the kicker by an incline on the end of the body of the gun acting
against the projecting tail end of the sear or holding back lever: Figure 10
represents an end elevation of the body of the gun and figure 11 represents the
horizontal sear or holding back lever detached.
The kickers represented in Figure 9 consists of a doubled blade spring
somewhat resembling an ordinary main spring seated in a box fixed to the fore
end f.
is
In this arrangement the crosshead arm 2 of the holding back lever h,
turned towards the front of the gun and the said cross head arm when it is
pressed inwards by the action upon it of the cranked lever n, n³, is made to project
in front of and cock or hold in a state of tension the spring kicker or ejector arm s.
The action of the cocking rod when the gun is discharged upon the cranked
evern, n² and the latter upon the sear or holding back lever h, is the same as I
have already described with respect to the ejector mechanism represented in
Figures 1, 2, 3, 4 and 5.
In this arrangement the withdrawing of the sear or holding back lever h, his
effected in the following manner.

page_text: The tail part of the said sear or holding back lever passes through and projects
from the abutment or joint of the bar of the fore end f and bears against an incline t
on the end of the body & so that on the opening of the gun the said projecting tail h
is by the action of the said incline t pressed inwards and the lever h, 2 turned on
its joint as indicated in dotted lines in Figure 11. The cross head of the sear or
lever is thereby withdrawn from the front of, and releases the, spring kicker or
ejector arms which by a sudden motion ejects the spent cartridge case from the barrel.
The arrangements of parts of ejector mechanism may be used with spring sliding
kickers as well as with jointed kickers or blade spring kickers.
In order to readily withdraw the fore end containing the ejector mechanism
from the barrel it is necessary that the spring kicker or kickers e, e or s should be
held in a state of tension. I effect this by means of a slide (forked in the case of
double guns) working on the fore end bar, the said slide being operated from the
boss or head of the hand lever by which the fore end is fastened to the barrel. The
branches of the forked slide work in guides in the fore end bar their ends being
hevilled. When the slide is advanced the bevilled ends of its branches act upon the
horizontal sears or holling back levers near their cross heads and cause the said heads
to engage upon or pass in front of and hold back or cock the spring kickers or
ejector arms.
Having now particularly described and ascertained the nature of my said
invention and the manner in which the same is to be performed I declare that
I claim as my invention of " Improvements in the ejector mechanism of drop down
small arms.
:
First The use in ejector mechanism of the horizontal sear or holding back lever
herein before described and illustrated in the accompanying Drawing for engaging
in front of and cocking or holding in a state of tension the jointed kicker or ejector
arm or blade spring kicker or ejector arın or spring sliding kicker of the ejecting
mechanism.
:
Secondly The combination with the said horizontal sear or holding back lever of
a cranked lever put into operation by the advance of the cocking rod on the
discharge of the gun the several parts being arranged and acting substantially as
hereinbefore described and illustrated in the accompanying drawing.
Thirdly The combination with the said sear or holding back lever of the releasing
or rocking lever herein before described and illustrated in Figures L. 2. 5 and 7 of
the accompanying drawing for withdrawing the said sear or holding back lever and
releasing the kicker or ejector arın for the ejecting operation on the opening of the
gun also the arrangement represented in Figures 9, 10, and 11 for the same
purpose in which arrangement the projecting tail end of the sear or holding back
iever is operated upon on the opening of the gun by an incline at the end of the body
of the gun.
Fourthly The new or improved blade spring kicker or ejector arm represented in
Figure 9 and markeds to be used with ejector mechanism.
:
Lastly Cocking the jointed spring ejector arms or kickers or blade spring
kickers for the removal of the fore end by operating upon the sears or holding back
levers by means of a slide having a bevilled ended arm or fork working on the
fore end as herein before described.
