Improvements in the Ejecting 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 this
invention to be as follows :—
My invention has for its object so to construct and arrange the ejecting mechanism
of drop down small arms that on raising the breech end of the barrel for charging
the case of a spent cartridge contained in the barrel will be discharged while a
live cartridge will not be ejected.
My invention is applicable to single and double barrel guns but as the ejecting
mechanism is the same in each barrel of a double barrel gun I will describe my
invention in connection with one barrel.
I employ an extractor of the ordinary kind excepting that I make the end of.
the extractor rod operated upon by the spring sliding bolt or ejector rod inclined
instead of at right angles to the axis of the rod. The end of the ejector rod which
bears against the inclined end of the extractor rod is also inclined. The said ejector
rod is surrounded by a strong coiled spring by which when liberated as hereinafter
explained the said ejector rod is urged forcibly forward and ejects the cartridge case.
When after charging the breech end of the barrel is shut down the fork of the
extractor comes in contact with the face of the break off and the extractor is forced
back. Its rod forces back the ejector rod compressing its spring and the said ejector
rod with its spring in a state of tension is held in that position or is kept cocked
in the following manner. The extractor rod works in a tubular recess in the lump
of the barrel and is capable of a sliding motion only. But the recess in the fore end
in which the ejector rod works permits of the front end of the said rod that is the
end against which the extractor rod bears to rise or fall. In consequence of the
inclination of the ends of the said rods there is a tendency in the front end of
the ejector rod to descend. But the front end of the ejector rod cannot descend
until it has been pushed home by the extractor rod. On the fore end is an angular
shoulder and when the extreme front end of the ejector rod reaches this point the
downward pressure exercised upon it by the inclined ends of the rods causes it to
descend and it is incapable of returning until its end has been raised from the
shoulder described. This raising of the front end of the ejector rod and its liberation
is effected by a small cranked lever underneath it which on being operated lifts the
inclined end of the ejectors rod and liberates it. The said cranked lever is operated
as follows. In the lower part of the body of the gun an inclined rod slides. This

upwards the front end of the ejector rod which escaping from the shoulder which
held it in cock is driven forcibly forwards by its spring against the extractor rod and

Improvements in the Ejecting 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 has for its object so to construct and arrange the ejecting mechanism
of drop down small arms that on raising the breech end of the barrel for charging,
the case of a spent cartridge contained in the barrel will be discharged while a live
cartridge will not be ejected.
My invention is applicable to single and double barrel guns but as the ejecting
mechanism is the same in each barrel of a double barrel gun I will describe my
invention in connection with one barrel.
The
I employ an extractor of the ordinary kind excepting that I make the end of the
extractor rod operated upon by the spring sliding bolt or ejector rod inclined instead
of at a right angle to the axis of the rod. The end of the ejector rod which bears
against the inclined end of the extractor rod is also inclined. Or the bearing ends
of the extractor and ejector rods may be at right angles to the axis of the rods
and the end of the ejector rod be pressed down at the proper time by a blade
spring on the fore end. The ejector rod is surrounded by a strong coiled spring
by which when liberated as hereinafter explained the said ejector rod is urged
forcibly forward and ejects the cartridge case. When after charging the breech end
of the barrel is shut down the fork of the extractor comes in contact with the face
of the break off and the extractor is forced back. Its rod forces back the ejector
rod compressing its spring and the said ejector rod with its spring in a state of
tension is held in that position or is kept cocked in the following manner.
extractor rod works in a tubular recess in the lump of the barrel and is capable of
a sliding motion only. But the recess in the fore end in which the ejector rod
works permits of the front end of the said rod, that is, the end against which the
extractor rod bears to rise or fall. In consequence of the inclination of the ends
of the extractor and ejector rods, or by the pressure of the spring on the ejector
rod, there is a tendency in the front end of the said ejector rod to descend.
the front end of the ejector rod cannot descend until it has been pushed home by
the extractor rod. On the fore end is an angular shoulder and when the extreme
front end of the ejector rod reaches this point the downward pressure exercised upon
it by the inclined ends of the rods or by the spring causes it to descend and it is
incapable of returning until its end has been raised from the shoulder described.
This raising of the front end of the ejector rod and its liberation is effected by a
small cranked lever underneath it which on being operated lifts the end of the ejector
rod and liberates it. The said cranked lever is operated as follows :-In the lower part
of the body of the gun an inclined rod slides. This rod is pushed forward by the fall
of the hammer as is well understood. In a slot in the knuckle of the joint is a small
hanging lever turning freely on its centre. The lower end of this hanging lever is
turned nearly at right angles towards the fore end and when the sliding rod is urged
forward it advances the hanging lever the end of which is thereby made to engage
under the longer arm of the cranked lever and on the opening of the gun, the
But

page_text: cranked lever lifts and disengages the ejector rod and effects the ejection of the spent
cartridge.
I will now proceed to describe with reference to the accompanying drawings the
manner in which my invention is to be performed.
Figure 1 represents in longitudinal vertical section and Figure 2 in horizontal
section partly in plan of underside, the breech end of a double barrel gun the parts
of the ejecting mechanism of which are constructed and arranged according to my
invention. In the said Figures 1 and 2 the ejecting mechanism is ready to eject the
spent cartridge cases on the raising of the breech end of the barrels ; Figure 3
represent the same view as Figure 1 after the barrels have been raised and the ejecting
of the spent cartridge cases effected; Figure 4 represents in elevation and plan a
portion of the ejecting mechanism represented in Figure 1 drawn to a larger scale;
Figure 5 represents the mechanism which I use for preventing the cocked ejector rods
being released when the fore end is removed from the body for stripping the gun.
The same letters of reference indicate the same parts in the several figures of the
drawings.
a is the extractor rod capable only of a sliding motion in the lump of the barrel
and is the spring sliding bolt or ejector rod working in the case c on the fore end d
and pressed outwards by the coiled spring e for operating the extractor rod a.
It will be seen by an examination of the drawing that the bearing ends of both the
extractor rod a and the spring bolt or ejector rod b are inclined. The ejector rod b
besides being capable of a sliding motion is also capable of a rising and falling
motion. In Figure 1 the ejector rod 6 is represented in its lowered and cocked
position and in Figure 3 in its raised and released position. The front inclined end
of the ejector rod 6 works over a recess f in the fore end d and in consequence of
the inclinations of the bearing inclined ends of the two rods a and b there is a tendency
in the front end of the ejector rod b to descend but the said front end of the ejector
rod cannot descend until it has been brought by the closing of the barrel into the
position represented in Figure 1, that is, has been pushed completely home by the
extractor rod a and brought over the recess f. When the extreme front end of
the ejector rod 6 has reached its fully pushed back position Figure 1. the downward
pressure upon it causes it to descend and engage with the angular or undercut
shoulder g in the fore end. The ejector rod b is thus put into a state of tension by
the compressing of its spring e and is cocked or held in a state of tension by its front
end engaging with the shoulder 9 as described and represented in Figure 1. Or the
downward pressure upon the ejector rod b to cause it when fully pressed home by the
extractor rod a to engage with the shoulder g on the fore end may be effected by a
spring as shown in the arrangement Figures 6, 7, 8 and 9; Figure 6 representing
the gun closed in longitudinal section and Figure 7 in plan, and open in longitudinal
section in Figure 8; Figure 9 represents an end elevation of the fore end. The
spring by which the ejector rods b, b of the double gun are pressed down is marked b³,
the cross head of the spring bearing upon both ejector rods. When the spring & is
employed the bearing ends of the extractor and ejector rods a, b are at right angles
to the axis of the said rods as represented and the extractor rod gives only a longi-
tudinal motion to the ejector rod on closing the gun. The front end of the ejector
rod bin both the arrangements shown is lifted from the shoulder g to release it for
operating the extractor rod a by means of the small cranked lever h, underneath it
the said cranked lever h being acted upon by the small hanging lever i at the
knuckle of the body. The cranked lever hand hanging lever i together with a
portion of the sliding cocking rod k are shown drawn to a larger scale in Figure 4.
The hanging lever is advanced by the cocking rod k when the latter is urged
forward by the fall of the hammer n to discharge the gun as illustrated in Figure 1
the advance of the hanging lever i causing its tail end to engage under the longer
arm of the cranked lever h h ready on the lifting of the barrel to act upon the
said cranked lever and cause it to lift and disengage the ejector rod 6 from the
shoulder g on the fore end. When the hammer n is in its cocked position the cocking
rod k is in its back position as illustrated in Figure 3 and the hanging lever i is

page_text: also in its back position and out of the range of the long arm h³ of the cranked
lever h, h as indicated in dotted lines in Figure 1. It is only on the fall of the
hammer n that the hanging lever i is put into its operative position, that is, in a
position to raise the cranked lever h, and thereby bring on the opening of the gun
the ejecting mechanism into operation. The hammer n is cocked on the lifting of the
breech end of the barrel to open the gun and the hanging lever restored to its normal
position out of the range of the cranked lever by the part of the said hanging
lever (see Figure 4) being acted upon by a lump or projection on the joint of the fore
end, the backward movement of the said hanging lever forcing inwards the cocking
rod and cocking the hammer n.
The action of the parts is as follows:-When the gun is ready for firing the ejecter
rod 6 is in its pushed back position. Its spring is in a state of tension and it is held
in this cocked position by its front end engaging with the angular shoulder g on the
fore end d as represented in Figure 1. The inclined cocking rod k is in its withdrawn
position shown in Figure 3 and iudicated in Figure 1 and the hanging lever is within
the knuckle of the joint of the body. When the gun is fired the sliding rod k is
pushed forward by the fall of the hammer n and the hanging lever i is made to
protrude from the slot in the knuckle and engage under the long arm h² of the cranked
lever h h. On raising the breech end of the barrel for cocking the hammer and
reloading the gun the parts occupy the respective positions represented in Figure 3,
that is, the descent of the fore end d causes the long arm h² of the cranked lever 1,
to strike against the tail or end of the hanging lever i ; the short arm h of the cranked
lever is thus raised and presses upwards the front end of the ejector rod 6 which
escaping from the shoulder g which held it in cock is driven forcibly forwards by its
spring e against the extractor rod a and thereby ejects the spent cartridge from the
barrel as represented in Figure 3. During the cocking of the hammer n its main
spring acting through the cocking rod k exerts a constant pressure on the hanging
lever i and releasing lever h 2 so as to keep them to their work and by their conjoint
action to lift and release the ejector rod b. The shutting down of the breech end of
the barrel restores the parts to their normal positions.
For the purpose of locking the cranked lever und preventing it acting upon the
cocked ejector rod b on the removal of the fore end for stripping the gun I use the
automatic holding lever p on the underside of the fore end, the said holding lever p
being brought into action on the removal of the fore end from the body. The holding
lever pis pressed upwards by a spring q acting on its heel, the free end of the lever
being provided with a projection p' which takes into a notch or depression ³ in the
cranked lever hand thereby prevents the rising of the said cranked lever and the
accidental release of the cocked ejector rod b. The holding lever p is held out of
action when the fore end d is in its place on the body, by the small saddle or staple like
bar the vertical ends of which work through holes in the fore end iron and are
pressed down by the barrel. When so pressed down they depress and hold out of
action the lever p as represented in Figures 1 and 3. When the fore end is removed
the saddle bar no longer being pressed down the holding lever p is raised by its
spring 9 and the free end of the said lever p engaging with the cranked lever h, h² as
represented in Figure 5 prevents its action on the cocked ejector rod b.
Having now particularly described and ascertained the nature of my invention
and the manner in which the same is to be performed I declare that I claim as
my invention of "Improvements in the ejecting mechanism of drop down small
arms":
First The combination with an ejector rod having a downward motion given to
its front end on fully closing the gun and thereby causing it to engage with a shoulder
on the fore end and cock the said ejector rod of a cranked releasing lever in the fore
end and a hanging lever in the body of the gun the said hanging lever being made to
engage by the fall of the hammer, acting through the cocking rod, under the long arm
of the cranked lever, the main spring of the hammer during the opening of the gun
exerting through the cocking rod a constant pressure on the hanging and releasing

page_text: levers to cause them by their conjoint action to lift and release the ejector rod the
several parts being constructed arranged and acting substantially as hereinbefore
described and illustrated in the accompanying drawings.
Secondly-The combination with the cranked releasing lever of the ejector rod of
the automatic holding lever described and represented in the accompanying drawings
for preventing the accidental releasing of the cocked ejector rod on removing the fore
end from the body.
