Improvements in Ejector Mechanism for Break-down Guns.
I, EDGAR HARRISON, of 142 New Bond Street, in the Parish of St. Georges,
Hanover Square, in the County of Middlesex, Gun Maker, do hereby declare the
nature of this invention to be as follows:-
The object of my invention is to simplify the construction and action of the ejector
mechanism of break down guns.
According to my invention I provide a tumbler in the forepart, barrel, or lump,
which is actuated by a spring connected at one end to the forepart and at the other
operating on the tumbler in such manner that on the discharge of the gun and the
opening of the barrels the said tumbler is caused to act on the extractor leg and to
eject the cartridge, but on the other hand if the gun is not fired the tumbler pushes
the extractor evenly up the face of action and thus loosens, but does not eject, the
cartridge.
For this purpose the tumbler is composed of three projecting arms or portions, one
acts on the extractor, the second is made angular or V shaped, with a projection on
its side nearest the action, and is acted on by the spring in the forepart, and the third
is acted on by the main spring or rod from the hammer. Near the knuckle in the
action there is a projection. The action of the spring in the forepart is to cause the
tumbler to act on the extractor leg, so that when the barrels are brought down or
opened and the gun is discharged the main spring has acted on the third arm of the
tumbler and swung the tumbler on its fulcrum in such manner that when the forepart
is brought down and the barrels are opened the second arm of the tumbler comes in
contact with the projection on the action thereby forcing the said second arm in the
contrary direction, till the spring in the forepart sharply acts on the angular part of
the second arm of the tumbler which latter turning quickly about its fulcrum forces
out the extractor leg; or the tumbler may be provided with a sear and bent so that
the mainspring acts on the tumbler and puts it into bent. When the gun is not fired
the mainspring not acting on the third arm of the tumbler the barrels can be brought
down without ejecting the unexploded cartridge from its barrel. The angular portion
of the second tumbler arm may be flattened at the apex of its angle.
In some cases I may dispense with the spring in the forepart and instead utilize the
force of the mainspring transmitted through the cocking lever which operation would
take place at the "overdraw" of the locks.

Improvements in Ejector Mechanism for Break-down Guns.
I, EDGAR HARRISON of 142 New Bond Street in the Parish of St. George's
Hanover Square, in the County of Middlesex, 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 :-
The object of my invention is to simplify the construction and action of the ejector
mechanism of break down guns, and my said invention will be best understood by
reference to the accompanying drawings on which Figure 1 represents in sectional
CD 37

page_text: elevation so much of a sporting break-down gun as will be necessary to illustrate my
improvements, Figure 2 being a similar view shewing the gun in the open position.
Figure 3 shews in section a somewhat modified arrangement of the extracting and
ejecting mechanism constructed according to my invention and Figures 4 and 5 shew
in the closed and open positions respectively another arrangement of the herein
described mechanism.
Figure 6 shews a view in which a sear is employed as hereafter described.
According to my invention I provide a tumbler A fulcrummed or pivotted in the
forepart, barrel or lump, which tumbler A is actuated by a spring C connected at one
end to the forepart B and at the other operating on the tumbler A in such manner
that on the discharge of the gun and the opening of the barrels the said tumbler A is
caused to act on the extractor leg D and to eject the cartridge, but on the other hand
if the gun is not fired the tumbler pushes the extractor evenly up the face of action
and thus loosens but does not eject the cartridge.
For this purpose and referring more particularly to Figures 1 and 2, the tumbler A
is formed with threo projecting arms or portions A', A2 and A³, one arın A¹ acts on the
extractor leg D, the second arin A2 is made angular or V shaped, with a projection A*
on its side nearest the action and the angular part A2 is acted on by the spring Cin
the forepart, and the third arm A is acted on by the mainspring or rod from the
hammer. Near the knuckle in the action there is a projection or a slot as indicated
at F in Figures 1 and 2. The action of the spring C in the forepart is to cause the
tumbler A to act on the extractor leg 1).
In Figure 1 it will be noticed that the three armed tumbler A is in such a position
(the gun being cocked) that the V-shaped arm A² is in advance, or in front of the
centre on which the tumbler A rocks, so that when the gun is discharged the forward
motion of the mainspring E acts on the tumbler arm A and the bearing of the arm A³
on the spring C is changed to the rear of the tumbler centre. When the forepart is
brought down and the barrels are opened the projection A on the second arm A² of
the tumbler comes into contact with the end of the slot Fin which it works and
thereby the arm A2 is forced forwards till the spring Cin the forepart sharply acts on
the angular part of the second arm A² of the said tumbler A which latter turning
quickly about its fulcrum strikes and forces out the extractor leg and ejects the
cartridge case.
If however the gun has not been fired and is opened while in the cocked position
as is shewn at Figure 2, the arm A2 bearing on the spring in front of the centre of
the tumbler will force the extractor gently outwards and loosen but not eject or throw
out the cartridge. The angular portion of the second tumbler arm may be flattened
at the apex of its angle.
In some cases I may dispense with the spring in the forepart and instead utilize the
force of the mainspring transmitted through the cocking lever which operation would
take place at the "over draw" of the locks.
Figure 3 illustrates one form of such an arrangement; the arm A³ of the tumbler A
has, as shewn, been dispensed with (although this is not necessary in all cases). The
V-shaped arm A2 is acted upon by the cocking lever G, the main spring E is
prolonged and acts on the rear side of the tumbler A above the centre.
On the gun being fired the main spring E advances and places the tumbler A in
the position shewn at Figure 3. On opening the gun the haminer H becomes cocked
and overdrawn and the projection A coming to the end of its slot in the action the
tumbler A is shifted or moved over as before and the fore end of the cocking lever G
acting as its spring causes the extractor to be forced out and at the same time allows
the hammer H to lose its overdraw.
Figures 4 and 5 illustrate an arrangement in which there is an intermediate lever J
between the cocking lever G and the tumbler A.
The tumbler A is cocked at the commencement of the action of opening the gun
after firing by means of the lever J. At or about the finish of the opening of the

page_text: barrels the rear end of the lever J working in the slot F comes to the end thereof
whereupon the fore end of lever J moves the tumbler A and places it in position so
that the spring C will act and cause the cartridge to he ejected.
On opening the gun without firing, there being no pressure on the cocking lever G
the lever J is not pressed upwards so that the tumbler A moves the extractor D
gradually up the face of the action and thus slowly extracts the cartridge without
ejecting. Instead of the V shaped edge, to the arm A² of the tumbler a roller may
be fitted.
When desired the tumbler may be provided with a sear and a bent so that the
mainspring may act on the tumbler and put the sear into the bent. Such an arrange-
ment is shewn at figure 6 the spring C is connected by a link C₁ to the arm A2 of the
tumbler A and the latter is formed with a bent or projection (shewn in dotted lines)
which underlies a sear K pivotted on the fore part and held in place by a spring K';
the tip or free rear end of the said sear K lies in the slot F of the action. The main-
spring E is prolonged as at Figure 3 and when the gun is fired the extended end of
the main-spring E cocks the tumbler A its bent taking into the notch of the sear K.
On the opening of the gun the tip of sear coming to the end of slot F releases the
tumbler A and the spent cartridge is ejected.
If the gun is opened and not fired the main-spring will not have forced the
tumbler A into such position that the sear K would fall into bent and consequently as
the gun is opened the extractors will be forced steadily backwards and the unexploded
cartridge will be loosened but not ejected.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
First. In ejector mechanism for break down guns the combination with the
extractors D of tumblers A pivotted in the fore part each of such tumblers being
formed with a downward projecting arm A2 actuated by a spring or an equivalent
therefor whereby on the discharge of the gun and the opening of the barrels the said
tumblers are caused to act on the extractor legs and to eject the cartridges whereas if
the gun has not been fired the cartridges are only loosened all substantially as
bereinbefore described and illustrated with reference to the accompanying drawings.
Second. In ejector mechanism for break down guns the combination with the
hammer H spring E and extractors D, of the three armed tumbler A spring C
carried by the fore part, together with slot F in action substantially as described and
illustrated with reference to Figures 1 and 2 of the accompanying drawings.
Third. In ejector mechanism for break down guns the combination with the
hammer H, mainspring E, cocking lever G and extractors D of the tumbler A
projection A and slot F in the action substantially as hereinbefore described and
illustrated with reference to Figure 3 of the accompanying drawings.
Fourth. In ejector mechanism for break down guns the combination with the
hammer H, mainspring E, cocking lever G and extractors D, of the lever J,
tumbler A, spring C and slot F substantially as herein before described and illustrated
with reference to Figures 4 and 5 of the accompanying drawings.
Fifth. In ejector mechanism for break down guns the combination with the
hammer H, spring E prolonged as shewn and the extractors D, of the tumbler A,
spring C linked to the lower extension A2, the sear K taking into tumbler bent and the
slot F in action all substantially as herein before described and illustrated with reference
to Figure 6 of the accompanying drawings.
Sixth. In ejector mechanism for break down guns the combination of the
tumbler A. slot F in action, lever G and mainspring E so arranged that the main-
spring effects the double purpose of cocking the tumbler A and communicating to it
of the
a resilient action substantially as set forth with especial reference to Figure
accompanying drawings.
