Improvements in or Connected with the Ejector Mechanism of
Small Arms.
We JOSEPH DALLAWAY, of 1 Aston Church Road, Washwood Heath, near
Birmingham, Gun action maker, and JOB Cox, of 23 Clarendon Street, Aston,
Birmingham, Gun action makor, both in the county of Warwick do hereby declare
the nature of this invention to be as follows:-
This invention relates to the ejecting mechanism of small arms, and has for its
object, an arrangement of parts, whereby the fire arm may be made to act at will,
either as an ejector, or as a non-ejector, also improvements in the arrangement of
parts for operating the ejecting mechanisin.
In carrying out our invention, we provide in the fore end, a recess or hole, to:
receive a sliding or ejecting bolt, which shall actuate the extractor, which former,
operates by means of a spring.
At a given point lengthwise of the fore end, a transverse hole is made, crossing
the upper part of the longitudinal recess or hole in the fore end, and at a point in
the sliding or ejecting bolt. corresponding to this transverse hole, a semi-circular
cross cut or groove is made. Fitted into this transverse hole, is a half turn pin,
having at a point, corresponding to the longitudinal ejecting bolt, a semi-circular
cross cut or groove, or its equivalent, so that its cut away portion permits of the sliding
motion of the ejecting bolt, while by a half turn, its left portion beds itself into the
semi-circular cross cut or groove of the ejecting holt, and prevents such sliding
motion. This cross pin is extended to the exterior of the fire arm, and suitably
formed for giving the half turn motion thereto.
Thus when the ejector is required to act automatically, the cross pin is turned free
of the ejector bolt, but when it is desired that the extracting shall bo at will, the
cross pin is turned so as to lock the said bolt in a given position, when it ceases to
act automatically.
This locking of the ejecting bolt may be varied in several ways, so that the cross
pin may be horizontally (as described) or may be vertically, and instead of turning
round, may be made as a sliding bolt, to engage with and retain the ejecting bolt in
a given position.
To operate the ejecting mechanism, we arrange that a sliding bolt or pin in
connection therewith, shall come in contact with, and be operated upon, by the trigger
of the gun, and not from the hammer, as is usual; so that upon pulling the trigger,
the bolt is pushed forward, thereby bringing the mechanism into position, for ejecting
the cartridge case, when the gun is opened; or, if desired, a more simple méthod
may be adopted, by causing the sliding bolt, to be operated by hand, by means of an
arm or its equivalent, extending to the outside of the plate, or gun stock.

Improvements in or: Connected with the Ejector Mechanism of
Small Arms..
We, JOSEPH DALLAWAY. of 1 Aston Church Road, Washwood Heath, near
Birmingham, Gun Action Maker, and JOB Cox of 23 Clarendon Street Aston,
Birmingham, Gun Action. Måker, 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 cartridge case expelling or ejecting mechanism, of breech-
loading small-arms, of the kind commonly called drop-down guns.
Figure 1 of the accompanying drawing, represents partly in elevation, and partly
in vertical section, a breech-loading drop-down gun, provided with ejecting mechanism,
constructed; arranged, and operated according to our said invention.. It will be seen
from the said section, that the extracting, mechanism. is worked perfectly independent
of the ejector mechanism, which is only brought into action, or is operated by the
user of the arm. Thus, the arm is an ejector-at-will, and not automatic, on the opening
of the barrels, as is common with guns of the ordinary construction.
Figure 2 represents an inverted horizontal section of the underside of the arm,
through the fore end, and with the body and stock removed. It will be seen that the
case from one barrel is ejected, while the live case in the other barrel, is only moved
outwards to an extracting distance.
Figure 3 represents a part vertical section and part elevation of the barrels of the
said arm, and which section is taken upon the dotted lines A B figure 2, whilst the
section of figure 1 is taken upon the dotted lines CD of the said figure.
Figure 4 represents a transverse vertical section, through the pushers or ejecting
mechanism releasers, an' upon the dotted lines EF figure 2.
Figure 5 is a top side plan of one of the ejector sear levers, and figure 6 is an
edge view of the same.
By providing guns; with ejecting mechanism at-will, the spent cases can be saved
if necessary, instead of being thrown away, as is the case with automatic expelling
mechanism.
The same letters of reference indicate corresponding parts in. the several
figures.
a are extractor. legs, working within the solid of the undersides of the barrels b, and
with their heads or hooked rear ends a², lying, within like shaped, recesses 6, formed
within the breech ends of the barrels. These extractors, or split extractors, are worked
by an arm or projection c², carried by the knuckles c, of the body of the gun,
and which projection c³,-takes and works within inside recesses or cut away parts a³,
of the extractor legs, and by the opening and closing of the breech ends of the barrels
of the gun, the extractors are moved to and fro as is usual.
d are ejector bolts or strikers; with coiled. springs e disposed. between their front
sides, and seats, and by means of which springs, when compressed, and. then released,.
the said bolts are driven rearwardly against the extractor legs, which thereby drives
forward the extractors, and expels the spent cases from the barrels.
The ejector bolts or strikers d, have rearwardly directed shoulders d², and upwardly
directed heads or lugs d, which latter strike the ejector legs..
gare sear levers, with their tail ends "hooked, which engage with the shoulders d'
of the bolts or strikers as aforesaid, whilst their fore parts g', which are the terminations
of the said sear lever, are formed into circular pressure plates, against which the
inner or nose ends of pushers h impinge, on the said pushers being pressed inwardly,
by the action of the thumb and finger of the user of the gun.
The sear levers are pivoted at 9, and are disposed and work horizontally within
opposite recesses of a box i¹, of the fore-end iron i.
-5

page_text: The pushers have collars or stops h', which work within holes, transversely
directed through the fore end-iron i, and fore-end *, and come against stop plate, let
within the opposite sides of the fore-end.
Disposed between the inside fore ends of the sear levers, is a coiled spring j, which
takes the pushers back to their normal positions, on pressure being relieved from
them, when the ejector mechanism or mechanisms of one or both barrels is or have
been released.
The ejector bolts or strikers d, impinge against a steel abutment plate k, let into the
joint part of the fore-end iron; so that after a bolt has struck an extractor rod end,
the same is arrested in its motion by the abutinent, but allows the extractor to
proceed further.
In figure 1, one of the heads of the ejector bolts or strikers, is shown in its ejecting
position, whilst the other head is shown in its neutral position, the same in figure 2.
The action of the extracting and ejecting mechanism of the arm, is as follows:-
The closing of the barrels after firing, presses inwardly the extractors, or split
extractors by the arm or projection e², pressing against the front shoulders of the
gaps a, and by such inward or forward movement, the ends of the extractor legs
come in contact with, and forcibly press upon the heads d³, of the ejector bolts or
strikers d, urging the said bolts forward, and compressing the coiled springs e,.
disposed between them, and their seats f, when the coiled spring j, turns the tail
end of the ejector sear lever g, and causes their hooked ends g', to engage with the
shoulders a², and thereby hold the said bolts or strikers under tension, which on being
released as herein-after described, flies rearwardly, and strikes the ejector legs.
When the ojector mechanism is in the aforesaid position, the extracting mechanism
works independently of it, and simply extracts like ordinary guns.
After firing, the user opens the barrels b, by the turning of the tang lever 1, aside,
and when the barrels have dropped, as in figure 1 pressure is applied to the pushers h
when the pressing of them inwards, compresses the coiled spring j, forces inwards
the rear ends of the sear levers g, and takes their hooked tail ends g¹, from
in front of the shoulders d', of the bolts or strikers d, when the said strikes are
urged forward with great velocity, and their heads strike the ends of the extractor
legs, which in turn are shot outwardly, thus expelling the empty or spent cases from
the barrels.
It will be understood that the ejector mechanism of one barrel, acts perfectly
independent of the ejector mechanisin of the other barrel; so that if the right hand
barrel only be fired, then the user on the falling of the barrels, presses inwards the
right hand pusher, which lifts the tail and hooked end of the right hand sear lever,
and so liberates the right hand ejector bolt or striker, which strikes the right-hand
extractor, or the right-hand split part of the extractor, and so expels the spent case
from the right hand barrel, as represented in figures 1 and 2 of the drawing.
Instead of releasing the ejecting mechanism by hand, through the intervention of
alpusher or pushers as described, a lever, or the equivalents of both of them, may be
employed with like effect.
We wish it to be understood, that the ejecting mechanism consisting of the bolts
or strikers d, coiled spring e, and horizontally working sear levers g, may be employed
for automatic ejection, by providing the said parts with a stop, which acts upon, or
is made to come against inclines on the fore parts of the sear levers, and these stops,
which are ejector slides, are operated by, or under the influence of the hammers,
triggers, or the ordinary sears; so that the falling of a hammer, the pulling of a
trigger, or the lifting of a sear, shall turn or move forward a sliding stop, into an
assigned position, which on the fully opening of the barrels, brings its fore-part, or
the stop part, in the path of an incline, or a lead, which by the one moving or wiping
against the other, causes the ejector sear lever to be lifted, and the said ejector bolt or
striker thereby released.
Our invention is applicable to single, as well as to double guns.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
