Improvements in Ejector Mechanism for Breech-loading Fire-arms.
I, JAMES MACNAUGHTON; of 26, Hanover Street, Edinburgh, in the County of
Midlothian, Gunmaker, do hereby declare the nature of this invention to be as
follows
This invention which relates to ejector mechanism for breech loading fire arms
principally consists in carrying the ejector apparatus in or by a slide which has a to
and fro motion on the fore part of the gun and so that in opening up the gun the
slide is by the ordinary extractor swivel fitted into the joint of the fore part caused
to move rearwards and thus when the cartridge is extracted to the usual distance
in breaking down the barrels the ejector strikers are close up to the ends of the
ejector rods and in action complete the ejection of the cartridge by a push instead
of by a blow or impact as formerly. The slide has at its rear end an opening in
which the tail of the extractor swivel is situated and it carries so as to slide with it
the ejector sears or the said sears may be swivelled on the fore part in which latter
case the ejector strikers do give a blow against the ejector rods in action. In
either case however the arrangement of the slide enables the first and best part of
the motion to be got out of the springs and the chances of breakage by concussion
are diminished.
The part of the slide in which the tail of the extractor swivel is situated acts as a
stop for the ejector rods instead of employing a pin or block for that purpose at
another part of the gun as heretofore, and these rods may be thrown back through
the action by making the sear and its spring V-shaped where they touch so that
when the sear is moved out by the drop of the barrels the spring pressure previously
exerted to hold it up against the face of the striker is exerted the other way sending
the heel of the sear back with a jerk against the rod.

Improvements in Ejector Mechanism for Breech-loading Fire-arms.
I, JAMES MACNAUGHTON, of 26, Hanover Street, Edinburgh, in the County of
Midlothian, Gunmaker, 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 which relates to ejector mechanism for breech-loading fire-arms
principally consists in carrying the ejector apparatus in or by a slide which has a
to and fro motion on the fore part of the gun and so that in opening up the gun the
slide is, by the ordinary extractor swivel fitted into the joint of the fore part,
caused to move rearwards and thus, when the cartridge is extracted to the usual
distance in breaking down the barrels, the ejector strikers are close up to the ends.
of the ejector.
The mechanism constituting the invention is illustrated in side elevation at
Figure 1, in plan of the upper and under sides respectively at Figures 2 and 3, in
back end elevation at Figure 4, in cross section on the line - Figure 2 at
Figure 5 and in detailed side elevation of the sliding part at Figure 6 of the
accompanying drawings, Figures 7 and 8 being views shewing the position with
relation to the ejector rods a in breaking down the fore part and when a full and
empty cartridge case respectively is contained in the barrel.

page_text: As shewn by these figures the ejector apparatus is carried by a slide which is
situated and has a to and fro motion in a recess in the upper side of the fore end
plate e the extent of the said motion in one direction being regulated by the
shoulders d, e and in the opposite direction by the slotted tail piece g through which
a pin passes into the plate c. In opening up the gun the slide is by the ordinary
extractor swivel, which is fitted into the joint of the fore part, caused to move
rearwards, the swivel having a tail formed on it and situated in a slot in the
slide, so that when the cartridge is extracted to the usual distance, in breaking
down the barrels, the ejector strikers are in contact with the ends of the ejector
rods a and in action complete the ejection by a push instead of by a blow or impact
as formerly and thus from the first of the movement of the springs and whilst
their action is strongest the springs are effective on the ejector rods a through the
pushers whereby the chances of breakage through concussion of the pushers on
the rods a are diminished.
The slide carries so as to move with it the ejector sears which are held up
against the ends of the pushers or strikers by springs and released, when the
cartridges have been fired, by the rods m which are pushed forward as usual on
the fall of the hammers the rods having each a heel which, in the act of breaking
down the barrels, acts against a similar heel on the sear so turning the latter on its
centre and releasing the nose or point of it from the end of the striker h. When
one or both of the cartridges is not fired the rod m, not being pushed forward, the
extractor mechanism remains inoperative in breaking down the barrels.
The part of the slide in which the tail of the extractor swivel is situated is
thickened or forms a lump and acts as a stop for the ejector rods a, whose forward
ends are also thickened to catch on the parts for that purpose instead of
employing a pin or block at another part of the gun as heretofore and in closing up
the barrels the lump on the extractor rods a acting on the strikers first pushes the
slide forwards and then pushes the strikers against the action of the springs j until
they are locked by the points of the sears i.
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
=
1. In a breech loading fire arm the arrangement of ejector mechanism substan-
tially as hereinbefore described with reference to the accompanying drawings.
2. In a breech loading fire arm carrying the ejector mechanism on a slide
substantially as described with reference to the drawings annexed.
3. In a breech loading fire arm the combination of a slide having a to and fro
motion and carrying ejector mechanism said slide being connected to the ordinary
extractor swivel and having a lump at its rearward end and ejector rods a having
like lumps the lumps acting as a stop to the rearward motion of the extractor rods a
substantially as set forth with reference to the appended drawings.
