Improvements in the Ejecting Mechanism of Breech Loading
•
Small-arms.
I CHARLES ROSSON of Market Head, Derby in the County of Derby, Gun Manu-
facturer 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:-
This Invention relates to improvements in cartridge case ejector mechanism, of
small arms, of the kind commonly called, drop down guns, rifles, and pistols, as
hereinafter described, whereby double or split extractors of double guns, are worked
independent of each other, in a simple and efficient manner.
Thus, if one barrel only of the pair of barrels be discharged, then the breaking
of the said barrels, only expels the spent cartridge case of that barrel, without
disturbing the unfired cartridge case, of the other barrel. On the other hand, if
both cases are fired, then both are expelled by spring ejectors, used in connection with
the extractors.
As the ejector mechanism for each barrel is alike, I will only describe one of
them.
The legs of the split or divided extractors, work within like holes made through
the solid metal of the undersides of the barrels, and with their naked front ends
extending forwardly and abutting against the rears of the ejector rods, which rods
may have extended rears, or they may lie in the same direct line as the legs of the
extractors; so that the said legs receive the direct impact of the ejector rods, which
work within longitudinal holes directed down the solid of the metal, of the fore
end iron.
The ejector rods, have shouldered or cut away parts formed within them, where-
with, or wherein, the fore parts of ejector sears engage, while the hind parts of the
said sears which are jointed, extend to the inside face of the joint of the fore-end iron,
and which rear parts are operated by sear liberating rocking levers which are worked
and secured by the scars proper, as hereinafter described.
The metal of the fore end joint under the rears of the ejector scars, is cut away,
for the protruding ends of the rocking lovers to approach the ejector sear tails, on the
breaking of the barrels.
The ejector rods are expelled rearwards by coiled springs, or by a kicker arm
actuated by a flat, or V shaped spring.
Working within a cut away part in the body of the arm, is a rocking lever whose
fore part extends a little beyond the joint of the said body, and preferably disposed
in juxta position to the side of the hammer lifter.
The rear end of this lever, which extends to near the back of the body, has its end
made preferably returned, or hook like, and which presses upon the underside of the
nose of the sear proper, when the hammer is cocked. When the lever is in this
position, as it normally assumes, when the ejector sears are not required to be worked,
the gun can be opened, without the ejectors, being operated.
The lifting of the tails of the sears, for the discharge of the gun, presses down-
wards the rear of the rocking lever, turns it upon its fulcrum centre, which is in a
position about midway between its ends, and raises the fore part to a slightly elevated
position, which is held in that position, by the nose of the sear proper resting upon
the underside of the hammer below the bent, and with the tail of the rocking lever
coming as before, upon the underside of the nose of the sear proper, thereby securing
the said rocking lever fixedly in position; so that on the breaking of the barrels,
the extractors are first operated, and on the fully opening of the said barrels, the
extended and elevated fore part of the rocking lever, presses upon the tail of the

page_text: ejector sear, and liberates its nose from a bent, notch or shoulder formed within or
upon, or in connection with the ejector rods.
Thus, the cocking of the gun by the opening of the barrels, takes the nose of
the sear into the bent of the hammer, and with the tail of the rocking lever coming
under the sear nose.
The hammer. lifter and fore end with barrels, is free to turn upon the body pin,
without operating the ejector mechanism, but on the discharge of the arm by the lifting
of the sear tail, the fore part of the rocking lever is raised or elevated and then
fixed, in a higher position, with respect to the ejector sear tails, by the top side of the
sear nose, coming upon the underside of the hammer when discharged.
The rocking lever is kept up to the sear proper by a flat spring.
Figure 1 of the accompanying drawings, represents in longitudinal vertical section,
a breech-loading drop-down double hammerless gun, provided with ejecting mechanism
constructed according to my invention It will be seen, that the said mechanism,
consists essentially of a rocking lever, with fore part curved downwards, and which
said curved part constitutes a stop for the lifting of the ejector sear tail, on the fully
opening of the barrels, and further, that the said rocking lever, is operated by the
sear proper, or a supplementary nose, directed upon its side.
Figure 2 represents a like section as figure 1, but with the barrels fully opened, and
a spent case in the act of being expelled-The position which the stop end of the
lever assumes, when the ejector sear is in the position as shown, is the dotted lines.
Figure 3 shows the said breech end of the arm, with the parts of the ejecting
mechanism in the positions which they assume, on the falling of the hammer, and the
positions which they take, for putting on ejection.
Figure 4 represents an inverted plan of the body part of the arm, showing the
extended stop ends of the rocking levers and the operating sears of them.
Figure 5 represents a side and top side plan of the sears.
Figure 6 a side view and top side plan of one of the rocking levers.
Figure 7 represents a hammer gun provided with my improved cartridge case
ejecting mechanism.
The
The same letters of reference indicate corresponding parts in figures 1 to 6.
a is the body of the arm, a² the knuckle joint thereof, the fore end, c the
barrels, d the hammer of the gun, d² the fore part of it, and d³ its rear underside,
against which, the inwardly extended sear nose e² of the sear-proper e, comes.
fore part of the limb of this sear proper, is formed with a seat e³, upon which, the
heel of the rear of a rocking lever f, takes and seats itself whilst the fore part of
the rocking lever, is curved downwards into an ejector sear stop f³, which when in
the position as represented in figure 3 causes the ejector sear tail ², of an ejector
sear g, to be lifted, and take its nose end g³, from out of a bent or notch 12, of a
striker rod, whose stem has a coiled spring impinging against it, and which
spring, is located within a hole j2 made longitudinally within the fore end iron j.
The head, of the striker rod h, impinges upon the end of the extractor leg k², of
an extractor k, which is worked by the lug a³, on the joint a², of the body part, in the
usual manner.
Z is the main spring, mis the hammer lifter, shown broken off, and is the joint
of the rocking arm f.
OPERATION.
The pulling of the trigger raises the sear tail, and releases the hammer, which
falls, and causes the scar nose e² to impinge upon the top side rear end of the rocking
lever, and lift it into the position as represented in dotted lines figure 2 and full
lines in figure 3, thus making the topside of the end f³, abut against the shoulder a¹,
and with the extreme fore part of the said end 3, in a stop position, against which
the ejector sear tail 2, impinges, on the barrels being fully opened; and which said
lifting, raises the nose g³, from the bent h², of a striker rod h, see figure 2, when the
stored up energy of the spring is released, and the striker rod urged forward with

page_text: considerable impetus which striking the ejector leg, drives the same rearwards or
outwards and by its momentum being suddenly stopped, the cartridge case is thereby
expelled, as represented in figure 2.
The closing of the barrel places the spring in a state of tension, and causes the
nose of the ejector sear, to snap into the bent as aforesaid, by the spring n.
It will be seen that when the gun is closed, and the hammer cocked, then the
forepart of the rocking lever f³, is out of the path of the sear tail, on the opening
of the barrels, and which lever is brought back into its neutral position by a spring o
when the same is free of the sear proper.
That the rocking lever is held in a fixed or stationary position, during the time
that its fore part forms a stop for the ejector sear tail to wipe upon, or impinge against,
is by the nose of the sear proper coming under the rear back underside d³, of the
hammer d, when the said hammer is in its thrown position, as in figure 3.
Thus, the lifting of the sear nose from the bent of the hammer, takes its top side
under the underside rear part of the hammer, thereby fixing the rocking lever, by
the sear nose pressing upon it.
The hammer gun figure 7-a is the body part, the fore end, c the barrels, d the
outside hammers, the rocking lever, its rear end, its fore and stop end, g the
cjector sear, and e the sear proper, whose nose end takes into a bent of the rebound
tumbler, whose fore part d³, comes upon the top rear part 2, when the hammer d
is down, as represented.
7 is the main spring, and 12 the sear spring.
The falling of the hammer or cock, tilts the rocking lever, and bring its fore part
into a stop position, whilst the rear part of it, is blocked and held by the tumbler
head, coming above it.
The raising of the cock by hand, takes the tumbler head out of its holding position,
and allows the rocking lever to be brought back, by a spring or otherwise, with its
fore end in a neutral position, for extracting only.
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. Operating ejector sears, of breech-loading ejecting mechanism, by a rocking
lever, with fore and rear parts, constructed substantially as described and set forth
in figures 1, 2, 3, 4 and 6.
Secondly. Locking, or holding the rocking lever in its stop or acting position,
by the impingement of a sear nose coming under the rear underside of the hammer,
substantially as set forth in figures 1 to 5.
Thirdly. The combination with a rocking lever, and hammer, as described, of a
sear e, e², e³, as set forth in figures 1 to 5.
Fourthly. The construction and arrangement of the parts of ejector mechanism
substantially as described and set forth, in figures 1, 2, 3, and 4.
Fifthly. In a hammer gun, the construction and arrangement of the parts of
ejector mechanism, as described and set forth in figure 1.
