Improvements in Ejector Mechanism for Breech Loading
Small Arms.
I, EDWIN GEORGE ANSON of Green Lane Small Heath Birmingham in the County
of Warwick, Gun Maker, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in ejector mechanism for breech loading
small arms of the kind called drop guns, rifles and pistols, as hereinafter described;
by which improvements, the extractors of double guns or arms described are worked
independently of each other; so that on the opening of the barrels, the empty case
or empty cases only are ejected; thus if one barrel only be discharged, the gun can
be opened and the empty case only ejected, without ejecting the other.
I will describe my improvements in connection with a double barrelled drop
down gun.
Either in slots in the body, or on the lock plates, enclose a spiral spring working
within a frame, and along one side and passing through one end of the said frame a
slide reciprocates, and which slide I hereafter call the ejector slide; that is, within
the forepart of the body of the arm, or upon the lock plates, a rectangular open frame
advances and retires in an oblique direction, and which said frame is governed by the
motion of the tumbler hereinafter described; and moving parallel with the top of
the frame is an ejector slide, which carries upon its front end a cross piece or double
arm while at its back end it carries a depending arm or angle piece, which crosses
and passes through slots in the sides of the frame and against the inside of this said
arm, and the inside of the front of the frame, a spiral spring is enclosed, and takes its
bearing. By this means, the spring thus enclosed, forces the ejector slide and frame,
in opposite directions. The spring is kept centrally within the frame by a bar which
passes through the spring and is connected to the two opposite ends of the said ejector
slide. The standing up arm of the slide last named, projects through the body of the
gun, and presses against the front of a turned down end on the fore part of an
extractor rod, and which said rod runs parallel with the barrels.
;

page_text: The back end of the reciprocating frame is attached to the breast of the tumbler,
by a pin working within a slot, while the front lower part of the frame (on the
opening of the barrels) comes in contact with the bottom of the fore end iron, and by
the curvilinear movement made by the former, the frame is pressed back, and with
it the tumbler. The backward movement of the frame compresses the spring between
itself and the ejector slide and cocks the arm.
Below the ordinary sear which engages with the tumbler, I provide what I call an
ejector or supplementary sear; that is, an independent sear or arm jointed on the
same or upon a different centre as the sear proper, but engaging with the hanging
arm at the back of the ejector slide. This ejector sear acts as a stop to hold back the
ejector slide, on the backward movement of the frame for the compression of the
spring (enclosed between the fixed and movable parts) on the cocking of the tumbler.
The ejector sear is controlled and moved out of its stop position, by the sear. proper,
which seats itself upon the top edge of the said ejector sear, and which sears are kept
in position by springs.
On the opening and closing of the gun, the action of the parts of the ejector
mechanism is as follows. The opening of the gun, makes the fore-end iron impinge
upon the front end of the frame, and presses the said frame backwards and with it the
tumbler connected at its back end, and during the time which the frame is being
urged backwards, the ejector slide is being held in a fixed position by the front end
of the sear coming at the back of its deponding arm; the result is, that the coiled
spring is momentarily compressed during the backward traverse of the frame, or until
the sear is about to engage with the tumbler bent, when the ejector slide is liberated
and strikes forcibly the front end of the extractor rod, by the energy given out by the
expanding spring, so as to compel the said rod to be rapidly projected forward, and
the empty case flirted from the open back end of the barrel.
The freeing of the slide is caused by a swell portion near the bent of the tumbler
pressing upon the nose end of the sear proper, on the tumbler being forced backward
for cocking; this depresses the ejector sear to below the end of the ejector arm which
then allows the said ejector slide to be forced back by the recoil of the spring, and at
the same time that the ejector slide is liberated, the nose of the sear proper engages
with the bent of the tumbler, so as to hold it to full cock.*
The closing of the barrels takes the extractor rod back to its former position, and at
the same time urges forward the ejector slide, which in its turn compresses the spring,
and is retained in its compressed condition, by the end of the ejector sear engaging at
the back of the ejector slide, thereby holding the parts in position ready for firing,
which is done by simply pulling the trigger, which releases both the nose of the bent
proper from the tumbler sear, and the nose of the ejector sear from the back arm of
the slide, which allows the hammer to fall.
The case not fired will simply be drawn out of the barrels as far as the action in
opening lifts the extractor, the ejector sear not having been pushed out of position by
the movement of the ordinary sear passing into bent.

Small Arms.
I, EDWIN GEORGE ANSON of Green Lane Small Heath Birmingham in the County
of Warwick, Gun Maker, do hereby declare the nature of this 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 relates to improvements in ejector mechanism for breech loading
small arms of the kind called drop down guns, rifles and pistols, as herein-after
described; by which improvements, the extractors of double guns or arms described,
are worked independently of each other; so that on the opening of the barrels, the
empty case or empty cases only are ejected; thus if one barrel only be discharged,
the gun can be opened and the empty case only ejected, without ejecting the other.
I will describe my improvements in connection with a double barrelled drop
down gun.
Either in slots in the body, or on lock plates, I enclose a spiral spring working
within a frame, and along one side, and passing through one end of the said frame, a
slide reciprocates, and which slide I hereafter call the ejector slide; that is, within
the forepart of the body of the arm, or upon the lock plates, a rectangular open frame
advances and retires in an oblique direction, and which said frame is governed by the
motion of the tumbler hereinafter described; and moving parallel with the top of
the frame, is an ejector slide, which carries upon its front end, a cross piece or double
arm, while at its back end, it carries a depending arm or angle piece, which crosses
and passes through slots in the sides of the frame; and against the inside of this said
arm, and the inside of the front of the frame, a spiral spring is enclosed, and takes
bearing. By this means, the spring thus enclosed, forces the ejector slide and frame
in opposite directions. The spring is kept centrally within the frame by a bar, which
passes through the spring, and is connected to the two opposite ends of the said
ejector slide. The standing up arm of the slide last named, projects through the body
of the gun, and presses against the front of a turned down end on the forepart of an
extractor rod, and which said rod runs parallel with the barrels.
The back end of the reciprocating frame is attached to the breast of the tumbler, by
a pin working within a slot, while the front lower part of the frame (on the opening
of the barrels) comes in contact with the bottom of the fore-end iron, and by the
curvilinear movement made by the former, the frame is pressed back, and with it the
tumbler. The backward movement of the frame compresses the spring between itself
and the ejector slide, and cocks the arm.
Below the ordinary sear which engages with the tumbler, I provide what I call an
ejector or supplementary sear; that is, an independent sear or arm jointed on the
same, or upon a different centre, as the sear proper, but engaging with the hanging
arm at the back of the ejector slide. This ejector sear acts as a stop to hold back the

page_text: ejector slide, on the backward movement of the frame, for the compression of the
spring, (enclosed between the fixed and movable parts) on the cocking of the tumbler.
The ejector sear is controlled, and moved out of its stop position, by the sear proper,
which seats itself upon the top edge of the said ejector sear, and which sears are kept
in position by springs.
On the opening and closing of the gun, the action of the parts of the ejector
mechanism is as follows.
The opening of the gun, makes the fore-end iron 'impinge upon the front end of
the frame, and presses the said frame backwards, and with it the tumbler connected
at its back end; and during the time which the frame is being urged backwards, the
ejector slide is being held in a fixed position, by the front end of the sear coming at
the back of its depending arm; the result is, that the coiled spring is momentarily
compressed during the backward traverse of the frame, or until the sear is about to
engage with the tumbler bent, when the ejector slide is liberated, and strikes forcibly
the front end of the extractor rod, by the energy given out by the expanding spring,
so as to compel the said rod to be rapidly projected forward, and the empty case
flirted from the open back end of the barrel.
The freeing of the slide is caused by a swell portion near the bent of the tumbler,
pressing upon the nose end of the sear proper, on the tumbler being forced backward
for cocking; this depresses the ejector sear to below the end of the ejector arm, which
then allows the said ejector slide to be forced back by the recoil of the spring, and at
the same time that the ejector slide is liberated, the nose of the sear proper engages
with the bent of the tumbler, so as to hold it to full cock.
་
The closing of the barrels takes the extractor rod back to its former position, and
at the same time urges forward the ejector slide, which in its turn compresses the
spring, and is retained in its compressed condition, by the end of the ejector sear
engaging at the back of the ejector slide, thereby holding the parts in position ready
for firing, which is done by simply pulling the trigger, which releases both the nose
of the bent proper from the tumbler sear, and the nose of the ejector sear from the
back arm of the slide, which allows the hammer to fall.
The case not fired, will simply be drawn out of the barrels as far as the action in
opening lifts the extractor, the ejector sear not having been pushed out of position by
the movement of the ordinary sear passing into bent.
Having described the nature of the said invention, I will now proceed to describe
with reference to the accompanying drawing, the manner in which the same is to be
performed.
Figure 1 represents partly in elevation, and partly in longitudinal vertical section,
one side of the breech end of a double barreled drop down gun, the ejector mechanism
of which, is constructed and arranged according to my invention, and which said breech
end is represented with the barrels closed, and the hammers cocked, ready for firing-
Figure 2 represents the same view as figure 1, but with the gun discharged-Figure 3
represents a like sectional view as figures 1 and 2, but with the barrels of the gun
tilted, and the gun open, and an empty cartridge case shown in the act of being
ejected from the chambers of the barrels-Figure 4 shows a front elevation of the
ejector slide. Figure 5 the ejector frame. Figure 6 a tumbler or hammer, and
figure 7 the ejector sear, while figure 8 shows the sear proper. Figure 84 is the
extractor. Figure 9 represents a rear end view of the barrels, showing the split
extractor, or independent extractors disposed side by side.
The same letters of reference indicate corresponding parts in the several figures of
the drawing; and as each barrel has independent ejector mechanism, which are alike
in construction, I will only describe one of them.
a a are the barrels, and b the break off, c is the fore end, and d the lock plate,
carrying the cartridge ejector mechanism; and which said lock plate is secured, and
let into one side of the breech body e. The body e has a body pin f, upon which the
barrels turn upon as a fulcrum, on being lowered or opened, for the ejection of a
spent cartridge, or for reloading. Thus on the opening of the barrels, an empty case
of one barrel, or the empty cases of both barrels, are ejected only after having been

page_text: fired, as the ejectors work independently of each other; and further, if one barrel
only is discharged, then the opening of the gun, will eject that case only, leaving the
other, and undischarged cartridge, undisturbed within its barrel chamber.
g is an extractor, or the one half of a split extractor, working loosely to and fro
within a cut away part in the underside of the barrel, on the opening and closing of a
gun. The rear part g2 of the said extractor, (when the barrels are closed) lies within
a gapped or cut away part in the end of one of the barrels made to receive it.
The other or front end, has a hanging lip or lug g³, and forms a projection, against
the front of which, a turned up, and hooked front end 2 of an extractor slide h
strikes, on the said slide being liberated, from its held-back position, while under the
influence, or the pressure of a spring i, encircling a fixed rod k, carried by the said
slide, and confined between one end of a gap or long slot of a tumbler carrying
frame, and the rear depending end of the said slide h.
The frame is jointed and connected to the tumbler m, by extending the back end
of the frame, into a lug, through which, and the breast of the hammer, a joint pin m³
passes, so that on the rising and falling of the tumbler, the frame is carried with it.
The said frame is also open at top, wherein the ejector slide works, with its depending
back end h³, working and protruding through a gap or hole, in the bottom back part
of the frame.
n is an ejector sear, jointed at n², and with its front or nose end, coming at the back
of the depending end h³ of the ejector slide h. The back of this ejector sear, has a
slight extension or short arm, upon which, the free end of a spring o presses. This
spring acts in common, for both the ejector sear, and the ordinary sear p, (other than
in figure 10) which has on its nose end, an outwardly extending lip p³, which presses
upon the top side of the ejector sear near its joint end. The tumbler is pressed home
by an ordinary spring q, which presses upon the rear of the said tumbler in the usual
way, also by the ejector spring.
The top of the front of the lock carrying plate, is made with a shoulder_part d³,
which presses upon the front of the extractor, on the barrels being open. Thus the
partial opening of the barrels, causes the extractor to travel slowly, some half its
traverse, this draws the cases from the chambers of the barrels, ready to be ejected on
the barrels fully falling.
The opening of the gun, when the parts of the ejector mechanism, are in the
respective positions as shown at figure 2, causes the shoulder of the lock plate or
its equivalent, to forcibly impinge upon the front of the extractor, and also causes the
fore end part 2 of the fore-end c, to also impinge or press upon the front of the frame.
The shoulder as aforesaid, presses the extractor somewhat half way back for starting
the cases from the barrels, prior to final ejectment, while the fore end part c³, presses
back the frame, and with it the tumbler to its cocked position, both of which are held
by the sear nose engaging with the bent of the tumbler.
During the time that the frame is making its backward traverse, the ejector slide
is held in a fixed position with respect to the body of the gun, by the nose of the
ejector sear, coming at the back of the back depending part of the slide, so that the
moving forward of the frame, causes the spring to be compressed between the inside
front part of the slot of the frame, and the inside back depending part of the ejector
slide, and is kept in its state of tension, by the holding of the frame and the ejector
slide as aforesaid.
Thus on the change of position of the parts as indicated and at or nearly at the
same time as the sear nose falls into the bent of the tumbler, the lower part m³ of the
said tumbler next to the bent, impinges upon the sear nose, and presses outwardly
the ejector sear, so as to remove its front or nose end, to below the back depending
end of the ejector slide, thereby liberating the said slide, which rebounds backward,
by the recoil of the spring, while its hooked end forcibly strikes the extractor, and
thereby automatically ejects the spent case from a barrel as represented in figure 3.
The closing of the gun, brings the face of the break off, against the back of the
extractor, pressing it forward, and with it, the ejector slide by the front depending
end of the said extractor, pressing against the inside hooked end of the slide, until the

page_text: back depending end of the slide is moved beyond the nose of the ejector sear, when
the latter falls at the back of the former, which thereby holds the slide and the spring
under compression.
The discharge of the arm by the pulling of a trigger, raises both sear proper and
the ejector sear, which allows the tumbler to fall forward, and the frame carried by it
to be moved forward, relaxing the tension of the spring, confined by it, but with the
ejector sear nose still at the back of the protruding end of the ejector slide, ready
for a subsequent opening of the barrels.
Figure 10 represents a modified form of my invention, in which the joint of the
ejector sear, is transposed from the sear proper to a position under the reciprocating
frame controlled by the tumbler. This sear has a shoulder n³, which engages at the
back of the ejector slide in the same way as previously described with respect to
the first arrangement.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
First. Putting ejector mechanism into a condition or state, suitable for ejectment,
by the fore-end, acting upon a reciprocating frame, or its equivalent, jointed at its
rear, to the breast of a tumbler, whereby the angular movement made by the said
fore end, on the opening of the gun, causes the frame and tumbler with it, to be
pressed backwards, at the same time that the spring is being compressed, and the
ejector slide held; substantially as described and set forth.
Secondly. Liberating ejector mechanism, by the lower part of the body of the
hammer, or its equivalent, an incline on the movable frame, pressing upon the ejector
sear, either directly, or through the intervention of the sear proper; substantially as
described and illustrated.
Thirdly. Giving the necessary impact to an extractor for ejectment, by an ejector
slide h, h³, h³, thrown forward by the reaction of a spring, and which said slide is
operated in the manner and for the purpose substantially as described and set forth.
Fourthly. Releasing ejector mechanism by a sear n in combination with an ordinary
sear p, as described and set forth in the several figures.
Fifthly. In automatic ejector mechanism of small arms, consisting of split extractor,
tumbler carrying frame, jointed to tumbler, ejector slide, rod and spring; ejector
sear with outstanding nose on ordinary sear, and fore end, with acting shoulder, and
inside projecting parts for starting extractor and pressing back the tumbler carrying
frame as aforesaid-The extractor mechanism, and the parts in connection therewith,
being constructed, arranged and working in the manner, substantially as and for the
purpose as herein described and set forth.
