Improvements in the Ejecting Mechanism of Drop-down Small-arms.
I SAMUEL BLAKEMORE ALLPORT of No. 50 Whittall Street Birmingham in the
County of Warwick Gun Manufacturer do hereby declare the nature of this invention
to be as follows:-
My invention has reference to drop down small arms having cocking mechanism
of the Anson and Deeley type and my said invention has for its object to effect by the
raising of the breech ends of the barrels the ejection of a spent cartridge case or
cartridge cases but to leave unejected by the raising of the breech ends of the barrels a
cartridge or cartridges which has or have not been fired.
My invention is especially applicable to double barrel guns but is also applicable to
single barrel guns. As in double barrel guns the essential parts are the same in both
barrels I will for convenience of description describe my invention in its application to
one barrel.
In constructing ejecting mechanism according to my invention I make the "dog"
or lever by which the hammer is cocked in two parts both parts turning on the centre
on which the barrel turns.
The two parts of the dog have stops at their joint by which the motion of each part
independent of the other part is limited to a small angle. The fore part of the dog
projects through the knuckle joint of the body into the fore end in which it engages
and of the motions of which it partakes. The rear part of the dog engages under the
cocking arm on the front of the hammer and the raising of the said rear part of the
dog cocks the gun. Under the fore part of the dog is a small sliding horizontal bolt
one end of which has a pin at right angles to it which pin engages between shoulders
or stops at the underside of the joint of the said dog. The said small sliding bolt
works with slight friction in a recess in the knuckle of the joint the required friction
being obtained preferably by slitting the said bolt through part of its length and
thereby giving it a slight elasticity.
In raising the breech end of the barrel for charging the rear part of the dog ascends
and cocks the hammer. The small bolt described is thereby moved towards the butt
end of the gun that is it is drawn within the knuckle of the joint and remains in that
position until the discharge of the gun. The fall of the hammer depressing the rear
part of the dog the said small bolt is forced forwards and its free end projects into a
recess in the fore end.
The ejecting mechanism operated by the parts described is constructed as follows:
On the top of the fore end is a tubular recess in which a cylindrical striker slides. A
strong coiled spring operates the said striker the said spring tending to urge the
striker towards the break off. The said striker carries at its acting end a projection
which bears against the end of the extractor rod.
When the barrel is shut down for firing a fixed driver on the knuckle of the joint
(which driver engages in a slot in the extractor rod) forces back the cylindrical striker
and compresses its coiled spring. On the front underside of the said striker is a bent
in which bent when the striker has been forced back a spring sear engages and holds
back the striker with its spring in a state of tension. The tail of the said sear extends
to the knuckle of the joint.
The action of the parts is as follows. When the breech end of the barrel is raised
the fore part of the dog is depressed the rear part of the dog is raised and the hammer
thereby cocked and held in its cocked position by the ordinary sear and bent. The
small sliding bolt is at the same time withdrawn into the knuckle. On depressing the
breech end of the barrel the ejector striker is forced back its spring is compressed and
it is retained in that position by the ejector sear. The breech end of the barrel may be
raised and lowered any number of times so long as the parts retain the positions
[DQ37

page_text: described without the ejecting mechanism operating. When however the hammer
falls on the discharge of the gun its cocking arm depresses the rear part of the dog
thereby projecting from the knuckle of the joint the small sliding bolt and bringing its
end within the range of the tail of the sear which holds the ejecting striker in cock.
If the breech end of the barrel is now raised the tail of the ejector sear striking against
the projecting end of the small bolt the said sear is withdrawn from the bent in the
ejector striker and the said striker is driven forcibly forward by its spring and the
case of the spent cartridge is ejected from the barrel. Thus the ejector mechanism is
only operated when the cartridge in the barrel with which it is connected has been
fired.
The ejecting mechanism may also be brought into operation by the following
modification of the parts.
I employ an extractor forcer somewhat resembling the ordinary kind to operate on
the extractor rod and eject the case of the spent cartridge. The jointed dog or lever
and the small sliding bolt by which the discharge of the ejected scar is effected are of
essentially the kind already described. The upper end of the forcer acts against the
end of the extractor rod. This forcer has on its lower part an arm at about a right
angle to the upper part. The said forcer has the requisite but limited motion
necessary for the ejection of the spent cartridge case. On shatting down the breech
end of the barrel after charging the extractor coming against the face of the break off
is pressed inwards. The forcer is pressed back by the extractor rod and the short arm
on the lower part of the forcer which bears on the extreme end of the free arm of the
mainspring depresses the said arm and puts the mainspring into a state of tension.
The spring is retained in this state by the vertical arm of the sear lever which arm is
forked the ends of the forked arm bearing on the mainspring. The end of the main-
spring situated near the sear lever is of different widths at different parts and when
the forked arm of the lever is over the broad part of the mainspring the free arin of the
. mainspring is prevented from rising but when by the changed position of the sear
lever its fork is brought over the narrow part of the spring the said spring can rise
(its narrow part ascending between the two branches of the fork) and the mainspring
can act on the forcer.
On raising the breech end of the barrel after discharge the small sliding bolt
having been projected from the knuckle of the body as hereinbefore described its end
is in the path of the horizontal arın of the sear lever. As the said lever descends by
the descending of the fore end by which it is carried the end of its horizontal arm
strikes against the end of the projecting small bolt. The sear lever is turned upon its
centre its forked arm is thereby brought over the narrow part of the mainspring which
being no longer held down rises rapidly and bearing against the underside of the arm
of the forcer urges the said forcer forwards and ejects the case of the spent cartridge.
A light spring tends to bring the sear lever to its normal position.

Improvements in the Ejecting Mechanism of Drop-down Small-arms.
I SAMUEL BLAKEMORE ALLPORT of No. 50 Whittall Street Birmingham in the
County of Warwick Gun Manufacturer do hereby declare the nature of my inven-
tion 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 reference to drop down small arms having cocking mechanism of 5
the Anson and Deeley type; and my said invention has for its object to effect by the
raising of the breech ends of the barrels the ejection of a spent cartridge case or cart-
ridge cases but to leave unejected by the raising of the breech ends of the barrels a
cartridge or cartridges which has or have not been fired.

page_text: My invention is especially applicable to double barrel guns but is also applicable to
single barrel guns. As in double barrel guns the essential parts are the same in both
barrels I will for convenience of description describe my invention in its application
to one barrel.
In constructing ejecting mechanism according to my invention I make the "dog"
or lever by which the hammer is cocked in two parts both parts turning on the contro
on which the barrel turns. The two parts of the dog have stops at their joint by
which the motion of each part independent of the other part is limited to a small
angle. The fore part of the dog projects through the knuckle joint of the body into
the fore end in which it engages and of the motions of which it partakes. The
rear part of the dog engages under the cocking arm on the front of the hammer and
the raising of the said rear part of the dog cocks the gun. Under the fore part of the
dog is a small sliding horizontal bolt one end of which has a pin at right angles to it
which pin engages between shoulders or stops at the underside of the joint of the said
dog. The said small sliding bolt works with slight friction in a recess in the knucklo
of the joint the required friction being obtained preferably by slitting the said bolt
through parts of its length and thereby giving it a slight elasticity. In raising the
breech end of the barrel for charging the rear part of the dog ascends and cocks
the hammer. The small bolt described is thereby moved towards the butt end of
the gun that is it is drawn within the knuckle of the joint and remains in that position
until the discharge of the gun. The fall of the hammer depressing the rear part of
the dog the said small bolt is forced forward and its free end projects into a recess in
the fore end.
The ejecting mechanism operated by the parts described is constructed as follows:
On the top of the fore end is a tubular recess in which a cylindrical striker slides. A
strong coiled spring operates the said striker the said spring tending to urge the striker
towards the break off. The said striker carries at its acting end a projection which
bears against the end of the extractor rod. When the barrel is shut down for firing a
fixed driver on the knuckle of the joint (which driver engages in a slot in the extractor
rod) forces back the cylindrical striker and compresses its coiled spring. On the front
underside of the said striker is a bent in which bent, when the striker has been forced
back, a spring sear engages and holds back tho striker with its spring in a state of
tension. The tail of the said soar extends to the knuckle of the joint.
The action of the parts is as follows:-When the breech end of the barrel is raised
the fore part of the dog is depressed the rear part of the dog is raised and the hammer
thereby cocked and held in its cocked position by the ordinary sear and bent. The
small sliding bolt is at the same time withdrawn into the knuckle. On depressing the
breech end of the barrel the ejector striker is forced back its spring is compressed and
it is retained in that position by the ejector sear. The breech end of the barrel may
be raised and lowered any number of times so long as the parts retain the positions
described without the ejecting mechanism operating. When however the hammer
falls on the discharge of the gun its cocking arm depresses the rear part of the dog
thereby projecting from the knuckle of the joint the small sliding bolt and bringing
its end within the range of the tail of the sear which holds the ejecting striker in cock.
If the breech end of the barrel is now raised the tail of the ejector sear striking against
the projecting end of the small bolt the said sear is withdrawn from the bent in the
ejector striker and the said striker is driven forcibly forward by its spring and the
case of the spent cartridge is ejected from the barrel. Thus, the ejector mechanisın is
only operated when the cartridge in the barrel with which it is connected has been
fired.
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 partly in longitudinal vertical section and partly in side
elevation and Figure 2 in plan of underside, partly in horizontal section, the breech
end of a double barrel drop down gun of the Anson and Deeley type containing
ejecting mechanism constructed according to my invention the barrels being represented

page_text: positions.
Figure 3 represents the said gun partly in longitudinal section and partly in
side elevation after the breech ends of the barrels have been raised from the break
off, the hammers cocked and the ejecting mechanism brought into action and the
spent cartridges ejected.
Figure 4 represents in end elevation and Figure 5 in side elevation a portion of the
body of the gun.
Figure 6 represents in side elevation and plan one of the jointed dogs or lifters of
the gun drawn to a larger scale and
Figure 7 represents in side elevation and end elevation the ejector striker drawn to
a larger scale.
The same letters of reference indicate the same parts in the several figures of the
drawings.
As the ejector mechanisms of both of the barrels of the double gun are alike
in construction and action I will describe the ejecting mechanism of one barrel
only.
a is the barrel; b the body; c the fore end and d the hammer; e, e³ is the dog or
lifter by the action of which the hammer d is cocked on the opening of the gun and
the ejecting mechanism released for ejecting the spent cartridge from the barrel the
said dog or lifter turning on the pin or centre f on which the barrel a turns. The two
parts e of the dog or lifter are capable of motion through a small angle on their
joint pin findependent of each other, the movement of the said parts being limited by
stops on them. That is, the rear part of the dog when the hammer has fallen has
the lowered position shown in Figures 1 and 6 and when the hammer is cocked the
said parte has the raised position shown in Figure 3 and indicated in dotted lines in
Figures 1 and 6.
The front part e of the dog projects through the knuckle of the
joint of the body and engages with slots in the abutment of the fore end iron in the
manner represented in the drawing so that the said part e partakes of the motions of
the said fore end. The rear part or long arm e of the dog projects backwards in the
body of the gun and its end engages with the cocking arm of the hammer d in the
usual way so that the raising of the said long arm of the dog effected by the action
of the fore end on the front arm or part e cocks the hammer in the usual way (see
Figure 3) is a small sliding horizontal bolt by which the releasing of the ejector
striker is effected, the said bolt working preferably with slight friction in the recess or
hole in the knuckle of the joint. (see Figure 2). The said sliding bolt
has at one
side and near its middle a pin i slightly wedge shaped which engages between the
shoulders or stops represented on the underside of the joint of the dog ee³. It is by
the motion of the dog acting through its stops that the sliding motion in one or other
direction is given to the small bolt g. On raising the breech end of the barrel for
opening and cocking the gun the sliding bolt g has the backward position given to it
represented in Figure 3, that is, the motion of the front part or arme of the dog
causes its stop to push back the bolt g thus withdrawing it within the knuckle of the
joint, the said bolt remaining in that position until the discharge of the gun. On the
fall of the hammer d the rear arm e³ of the dog descending into the position represented
in Figure 1 causes its stop to force forward the small bolt into the position
represented in the said Figure 1 its front end projecting into the recess in the fore
end ready on the opening of the gun to cause the ejecting mechanism to be discharged
as hereinafter described."
k is the cylindrical hollow striker in the fore end for operating upon the extractor
rod in the barrel. The said cylindrical striker k is represented separately drawn to a
larger scale in Figure 7. It consists of a tube having a head at its rear for acting
upon the extractor rod 7 the said tube sliding in a tubular recess m in the solid body of
the fore end iron (see Figures 1 and 3) and being urged towards the break off by the
compressed coiled spring situated within the said tubular striker. The recess m
in which the striker works is covered by the plate p; q is the spring sear by

page_text: which the cylindrical striker k is held in its cocked position the hooked end of
the said sear engaging with a bent or recess in the front of the head of the
said striker. The tail or rear end of the sear y extends to the knuckle of the
joint and is in the path of the front end of the sliding bolt when the latter is
in its advanced position Figure 1.
On the knuckle end of the body is a fixed driver working in the slot
in the extractor rod 1 (see Figures 1 and 3) for forcing back the striker & and
compressing its coiled spring n on the shutting down of the barrel; that is, on
the shutting down of the barrel the fixed driver by bearing against the front
of the slot prevents the extractor rod from advancing with the barrel and as
the temporary fixed extractor rod bears against the striker k the latter is also
prevented from advancing and consequently is put in a state of tension by its
spring being compressed by the advance of the fore end into the position shown
in Figure 1 when the sear y engaging with the striker holds it in its cocked
position.
The action of the ejecting mechanism is as follows:-The gun having been
discharged, the parts occupy the respective positions represented in Figures 1
and 2; that is to say, the ejector striker k is in its cocked position and the descent
of the rear long arm of the dog or lifter has caused the sliding bolt g to be
advanced into the path of the tail of the ejector striker sear
On the opening
of the gun the tail of the said sear a striking against the bolt g is disengaged
from the bent in the cocked ejoctor striker & which being released is driven
forward by its spring n and acting against the extractor rod / causes the latter
to eject the spent cartridge from the barrel as represented in Figure 3.
By the
opening of the gun the rear part of the dog is raised and the hammer
cocked by it the said rear part of the dog remaining in contact with the cocking
arm of the hammer as illustrated in Figure 3. By the depressing of the front
parte of the dog the sliding bolt is brought into its withdrawn position in
which position it is inoperative on the sear for releasing the ejecting mechanism,
so that the breech end of the barrel can be raised as often as may be necessary
before the gun has been discharged without ejecting the unfired cartridge the
sliding bolt g being only brought into its operative position for releasing the
ejecting mechanism by the fall of the hammer to discharge the gun as represented
in Figure 1 and hereinbefore fully described.
Instead of making the front end or part of the dog or lifter project into a slot
in the fore end of the gun and be operated directly by the fore end the fore end
may operate a slide and the latter the dog or lifter.
This modification of my invention is represented in connection with a double
barrel gun in side elevation partly in section in Figures 8 and 9; plan of under-
side partly in horizontal section (with the cover plate removed) in Figure 10.and
the gun opened and the extracting mechanism brought into action in Figure 11.
In Figures
and 11 a portion of the front lump on the barrel is indicated in
dotted lines: Figure 12 represents the two parts of the jointed dog or lifter of
the modified gun drawn to a larger scale. The section of Figure 8 is taken
through the projections on the fore end and slide and the section of Figure 9 is
taken through the slide where the stud on the dog engages with it.
In this modification the front part e of the dog or lifter is made shorter than
that of the dog or lifter in the gun already described and the said short front
part e is confined wholly within the body of the gun. On the underside of the
said short parte of the dog is a pin or stud 3 which takes into a hole r in the
slides working on the underside of the body. The nose of the front lump on
the barrel when the gun is closed takes into a slot in the said slide 8.
A pro-
jection on the front of the slides works in a slot in the cover plate of the
body b; g is the sliding bolt connected to and operated by the dog for releasing
the ejector striker k of the ejecting mechanism.
In Figures 8, 9 and 10 the hammer d is represented in its fallen position and

page_text: :
the gun discharged and the releasing bolt y brought into its forward position as
well as the slide s.
In Figure 11 the gun is represented opened and the case of the exploded cart-
ridge ejected and the releasing bolt 9 returned to its inoperative position within
the knuckle and the slides in its back position.
The slides is pushed back and the dog operated by it to cock the hammer and
withdraw the sliding bolt of the ejecting mechanism on opening the gun by
means of the projection t at the middle of the iron of the fore end e bearing
against the projection at the front end of the slides the said projection u
working in a slot in the cover plate of the body of the gun. As the slides is
pushed back by the fore end c the said slide carries with it the stude of the dog
and the latter is turned on its joint pin fand the hammer d is cocked in the
mauner represented in Figure 11, the operating sliding bolt g at the same time
being withdrawn out of the range of motion of the sear q the action of the parts
being substantially the same as that of the corresponding parts of the arrange-
ment first described in which the dogs or lifters are operated directly from the
fore end.
On closing the gun the nose of the front lump on the barrel passes into the
slot y in the slides and pressing against the projection on the said slide forces
it forward into the position represented in Figure 8. By the forward motion of
the slides the stud e embraced by it also carries forward the part e of the dog
leaving the rear part of the dog in the elevated position represented in
Figure 11 and the releasing bolt y in its retired position. The gun is now ready
to be discharged the fall of the hammer d causing the arm e² of the dog to carry
forward the releasing bolt g into its operative position Figure 8 ready on the
opening of the gun to effect the ejection of the spent cartridge.
Instead of using in combination with the ejecting mechanism described and
represented in Figures 8, 9, 10, 11 and 12 a jointed dog or lifter for operating
the sear releasing bolt a solid or unjointed dog may be used, that is, a dog the
limbs or arms of which are incapable of independent motion the said unjointed
limbs turning on the joint pin by the motion of the fore end and slide.
When a solid dog is used in combination with the slides the slot in the
slide in which the stud e is engaged is made of a length equal to the motion of
the slide so that on giving tho forward motion to the slide on the closing of the
barrel it does not operate upon the dog the rear arme of the solid dog being
left in its lifted position Figure 11. The releasing bolt g is thereby left in its
withdrawn position until the fall of the hammer. It will thus be understood that
when a solid dog is used the slides is operative only in its back motion for
cocking the hammer and causing the withdrawal of the releasing bolt 9:
instead of connecting the sear releasing bolt g to the jointel or solid dog or lifter
by a stud on the said bolt taking into a recess in the dog the connecting parts may
be reversed, that is, a stud on the front part of the dog may take into a recess
in the sear releasing bolt.
and
I do not limit myself to the position of the sliding releasing bolt g represented
in the drawings as the said bolt instead of having a horizontal motion parallel to
the body of the gun may be arranged to work at any desired angle with respect
to the body of the gun.
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 smal
arms
وو
First The combination with a jointed dog or lifter by which the cocking o
the hammer on the opening of the gun or small arm is effected of a sliding sea
releasing bolt engaged with and operated upon by the said dog the motion of the
rear part of the dog on the discharge of the hammer forcing forward and bringing

page_text: the said sear releasing bolt into the path or range of motion of the sear by which the
ejector striker is held in its cocked position so that on the opening of the gun
the said sear striking the releasing bolt is withdrawn from the bent in the ejector
striker and the ejecting mechanism put into action the said sear releasing bolt
being withdrawn into its inoperative position on the closing of the gun, the several
parts being constructed and arranged and working substantially as hereinbefore
described and illustrated in Figures 1, 2, 3, 4, 5 and 6 of the accompanying
drawings.
Secondly The combination with a jointed dog or lifter or a solid or unjointed dog
or lifter by which the cocking of the hammer is effected of a sliding sear releasing bolt
and a slide on the underside of the body of the gun or small arm the said slide being
engaged with a stud or its equivalent on the underside of the dog or lifter and being
acted upon to operate the dog or lifter for cocking the hammer and withdrawing the
sear releasing bolt on the opening of the gun by a projection on the fore end acting
upon a shoulder on the slide the several parts being constructed and arranged and
working substantially as hereinbefore described and illustrated in Figures 8, 9, 10,
11 and 12 of the accompanying drawings.
Thirdly The combination in ejecting mechanism of drop down small arms of
a tubular ejector striker as herein before described and illustrated in Figures 1, 2, 3
and 7 of the accompanying drawings for enclosing the coiled spring by which the
striker when released is driven forward the said tubular ejector striker working in
a groove in the solid body of the fore end and being covered by a cover plate as
described and illustrated.
