PROVISIONAL SPECIFICATION.
Improvements in the Ejector Mechanism of Drop Down Guns.
I, GEORGE LILLEYMAN, of 31 Manor Road, Stoke Newington, in the County
of Middlesex, Gentleman, do hereby declare the nature of this invention to be as
follows:-
The object of the present invention is to provide means whereby the action of
firing the gun will bring a part into the requisite position to cause it to release the
ejector mechanism (which may be of ordinary construction) as the barrels are
dropped, and the action of dropping the barrels will at same time return such part
to its original position ready to be acted upon again upon a fresh discharge.
For this purpose a slide, bar or rod is arranged so that its rear end is in the line
of travel of the hammer as same descends in firing the gun, so that the hammer
will force such slide, bar or rod forwards, and bring its forward end into the
position for acting upon the sear of the ejector mechanism and thus release same
when such sear turns with the barrels in opening the gun. Near its forward end
the slide, bar or rod carries a projection, which as the slide moves forward acts
upon a second slide or rocker which is in the line of travel of the ejector hammer
or striker which the sear holds back. The second slide or rocker is carried
forward by the forward movement of the first slide or bar, and when the ejector
hammer or striker moves forward (under the impulse of its spring) it carries the
second slide or rocker back again, and this in its turn acts upon the projection
on the first slide, bar or rod, and carries it back again to the position in which it
will be ready to be forced forward when the firearm is again discharged.
When convenient the first mentioned slide, bar or rod may be so situated that
its forward end may be acted upon directly by the ejector striker or hammer in
order to force it back again, instead of through the intermediary of the second
named slide or rocker.
Or again, instead of the ejector hammer or striker acting upon either the second
slide, or the first slide, bar or rod, in order to return same to its original position,
such hammer or striker in its movement to eject the cartridge may cause the sear
to turn and so force such slide, bar or rod back to its former position.

COMPLETE SPECIFICATION.
Improvements in the Ejector Mechanism of Drop Down Guns.
I, GEORGE LILLEYMAN, of 31 Manor Road, Stoke Newington, in the County
of Middlesex, Gentleman, 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 the present invention is to provide means whereby the action of
firing the gun will bring a part into the requisite position to cause it to release the
ejector mechanism (which may be of ordinary construction) as the barrels are
dropped, and the action of dropping the barrels will at same time return such part
to its original position ready to be acted upon again upon a fresh discharge.
For this purpose a slide, bar or rod is arranged so that its rear end is in the line
of travel of the hammer as same descends in firing the gun, so that the hammer

position for acting upon the sear of the ejector mechanism and thus release same
when such sear turns with the barrels in opening the gun.
In the accompanying drawings
Fig. 1 is a longitudinal section of a gun showing a suitable method of carrying
my invention into effect, the parts being in the position they occupy before the gun
is discharged.
Fig. 2 is a transverse section of Fig. 1.
Fig. 3 is a similar view to Fig. 1 showing the parts in the position they occupy
after the discharge of the gun.
Fig. 4 is also a similar view to Fig. 1, showing the position of the parts when
the barrels are partially dropped or opened, and
Fig. 5 is another longitudinal section of the gun shown in Fig. 1, showing the
position of the parts when the barrels are wholly dropped or opened.
Fig. 6 is a longitudinal section of a gun showing a slightly modified form of my.
invention.
Fig. 7 is a longitudinal section of a gun showing a further modification in the
manner of carrying my invention into effect.
In all the figures similar letters indicate corresponding parts.
The drawings show the invention as applied to a double barrelled gun,.but as
the parts and their action are identical for each barrel I shall only describe saine
with reference to one of the barrels.
Referring to Figs. 1. to 5 inclusive, A is the hammer of the gun pivotted at a and
operated in the usual or any approved manner. A slide, bar or rod B is fitted in a
recess in the side of the part D to the fore end of which the barrels C are pivotted
atc, and the rear end of such slide, bar or rod B is in such a position that when the
hammer A descends a projection, a' thereon comes in contact therewith. The rear
end of slide B is split or divided and the lower arm forms a spring having a notch
or bent.near its rear end which normally engages a fixed-stop-E-when-the-slide
is in its backward position, as shown in Fig. 1. The projection a on hammer-A-is-
so shaped that as the latter descends to fire the gun, such projection does not come
in contact with the end of, the-upper arm 2 of slide B, but does come in contact
with the end of armb of such slide,. which it forces down until the notch or bent
is disengaged from stop E, when the further movement of the hammer forces the
slide B-forward, a second notch or bent on arm of the slide limiting its forward.
movement by coming in contact with stop E, as shown in Fig. 3. This forward
movement of slide B has caused the end 64 thereof to project forward beyond. the
part in which it slides and to which the barrels Care pivotted.
The sear F of the ejector mechanism (which is or may be of ordinary construc-
tion), has an arm or projection on the opposite end to that which retains the
ejector hammer G. in position, such arm extending downwards and having at its
upper end a lip f¹. When the parts are in the position shown in Fig. 3, if the gun
is opened, the end of slide B will, as the barrels C drop by turning on their
pivot c, be brought into contact with lip of the ejector sear F, (as shown in
Fig. 4), and the further movement of opening the gun will force: one end of the
sear upwards.and thus cause its opposite end to be disengaged, from, the ejector
hammer G (as shown in Fig. 5) which will be thrown forward by its spring and so
eject the shell of the discharged cartridge in the usual manner. A-projection-on
the ejector hammer as the latter is forced forward. by its spring causes the sear F
to turn still further on its pivot. At the same time the hammer A will have been
recocked by the cocking lever in the usual manner, thus removing the projection a¹
out of contact with the rear end of slide B. The turning of the ejector sear Fon
its pivot will have caused the lower end of arm thereof to bear against the end 64
of slide B, and so force such slide back again to the position shown in Figs. 1 and 5,
ready to be acted upon by projection a' on hammer. A, when the latter again
descends. As the barrels are again closed the ejector mechanism, will be brought
back to its original position in the usual manner, sear F again engaging the ejector

page_text: hammer under the action of its spring. Upon the barrels being again opened the
action above described will be repeated if the gun has been first discharged.
Fig. 6 shows a slightly modified manner of carrying my invention into effect the
arrangement of the parts being somewhat different to that above described, but the
action being similar. In this case a lip on the end of slide B engages the nose
of the arm of the ejector sear F, so that as the gun is opened such sear is caused
to turn on its pivot, whereby arm forces back the slide B again until the sear
clears the lip At the same time the turning of sear F has freed the ejector
hanımer G and so permitted the ejecting mechanism to operate in the usual
manner.
Fig. 7 shows a still further modification of my invention in which the slide B is
returned to its original position by a second bar or slide. B₁ with which the ejector
hammer G engages, so that in its movement to actuate the ejector mechanism it
throws such second slide backwards and brings same in contact with the slide B,
and thus forces same back to its original position. As the ejector hammer G is
forced back in closing the gun again, it carries slide B¹ back with it.
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 :-
In drop down guns
1. The employment of a slide, bar or rod the rear end of which is normally
forced against and engages a fixed stop, in combination with a projection on the
firing hammer which when the hammer descends comes in contact with the end of
the slide, bar or rod, so as to disengage same from the fixed stop and force such
slide, bar or rod forward, whereby the forward end of the latter is brought into
position to act upon the sear of the ejector mechanism by the movement of opening
the gun, so as to cause such sear to release the ejector mechanism, substantially as
specified.
2. The employment of a slide, bar or rod B which is forced forward by the
descent of the hammer A. to a position to cause its forward end to act upon the sear
of the ejector mechanism when the gun is opened, and be forced back to its original
position by the action of said scar when the gun is reclosed, substantially as
specified.
3. The combination with the slide, bar or rod B acted upon by the projection a¹
on hammer A, so as to release the ejector sear F when the gun is opened, of an
arm carried by such sear F, and which as the latter turns forces the slide, bar or
rod B back to its original position, substantially as specified and as shown in
Figs. 1 to 5 inclusive of the drawings.
4. The combination of the slide, bar or rod B acted upon by projection a¹ on
hammer A and having a lip 6 on its forward end to engage the nose of an arm ƒ
on the ejector sear F, when the gun is opened and the slide B is in its forward
position, such arm f as the sear turns on its pivot forcing back the slide B to
its original position, substantially as specified and as shown in Fig. 6 of the
drawings.
5. The combination of the slide, bar or rod B acted upon by projection a' on
hammer A so as to bring its forward end in position to engage the ejector sear F,
and turn same when the gun is opened, thus releasing the ejector mechanism, and
of a second slide, bar or rod B¹ with which the ejector hammer G engages, and in
its movement to eject a discharged cartridge forces same backwards, and brings it
in contact with slide B, thereby returning the latter to its original position, substan-
tially as specified and as shown in Fig. 7 of the drawings.
