page_text: ARTHUR GRANT, of 674 St. James' Street, Pall Mall, London, in
the County of Middlesex, Gun Maker, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improved mechanism for ejecting the cases of discharged
5 cartridges from the barrels of drop down guns, and it consists essentially in utilizing
the movement of the locking bolt of such guns to release a spring bolt by means
of which the ejector is actuated.
The ejector is of known construction and consists of a plate fitting flush into a
recess in the breech end of the barrels, to the bores of which it conforms, and having
in its outer surface a recess to receive the head or rim of the cartridge case.
This plate is capable of being moved away from the barrels, thus drawing out the
cartridge case with it.
When the barrels are unlocked by releasing the locking bolt in the usual manner,
the first movement of the barrels in order to open the breech causes a cam to force
the ejector outward a short distance by acting upon a stem connected with the
ejector, thus forcing the cartridges slightly out from their seats in the chambers
and making them ready to be ejected by the continued movement of the ejector when
the barrels have been sufficiently opened.
The whole of the parts above described are of well known construction and
operate in the usual manner, and I have only described same in order to enable my
invention to be understood.
My invention consists in the following arrangement for effecting the further
forward movement of the ejector and so removing or ejecting the cartridge cases.
The rear end of the locking bolt is provided with an arm situated between two
heeks of a pivoted lever, one end of which is connected to a slide or bar. The
nd of the lever, between the cheeks of which such arm is situated, is made in the
orm of a spring and constitutes one cheek, to which the opposite cheek is connected
y a cross piece passing over the locking bolt arm, sufficient space being left
[Price 8d.]

page_text: between the cheeks to receive the arm and allow a certain clearance. The arm is
provided with a notch and in its normal position the second named cheek of the
pivotted lever engages such notch, so that the movement of the locking bolt will cause
the lever to turn on its pivot.
When the hammer of the gun is cocked, a projection thereon bears on the side of
the spring arm of the lever and forces it towards the locking bolt arm, whereby
the other cheek of the lever is removed from the notch in such arm, and consequently
the movement of the locking bolt will not actuate the lever, whereas when the
hammer has fallen the projection thereon ceases to bear on the spring arm of the
lever, and consequently the cheek of the latter will engage the notch in the locking
bolt arm and the movement of the bolt will consequently actuate the lever as
described. As the movement of such lever is utilised to effect the further move-
ment of the ejector, it will be seen that unless the hammer has fallen the action of
opening the barrel will not effect the ejection of the cartridge.
The movement of the lever above described causes the plate or slide connected
to the other arm thereof to be moved into such a position that the action of opening
the barrels will cause such slide to act upon a sear or catch and release it from a
notch in a spring bolt, and such bolt being thus released acts upon the stem of the
extractor forcing the extractor suddenly forward to its full extent, thereby ejecting
the cartridge cases.
The movement of closing the gun compresses the spring bolt again and causes the
sear to retain it until the locking bolt is again actuated by its hand lever, when (if
the hammer has previously fallen) its movement is transmitted as above described
through the pivotted lever to the slide which acts upon the sear.
The above arrangement can be applied to either single or to double barrelled drop
down guns, in which latter case the locking bolt is provided with a second arm, and
the other parts are duplicated, so that the ejector mechanism for each barrel will
act independently of the other, and consequently if only one barrel has been
discharged, the case of the discharged cartridge will be ejected when the gun is
opened, without ejecting the cartridge from the other barrel.

page_text: SAMUEL ARTHUR GRANT, of St. 674 James' Street, Pall Mall, London, 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 :-
This invention relates to improved mechanism for ejecting the cases of discharged
cartridges from the barrels of drop down guns, and it consists essentially in utilizing
the movement of the locking bolt of such guns to release a spring bolt by means of
which the ejector is actuated.
In the accompanying drawings Fig. 1 is a longitudinal section of a drop down gun
having my invention applied thereto.
Fig. 2 is another longitudinal section of same taken in a different plane.
Fig. 3 is a corresponding view to that shown in Fig. 2, but with the parts shown
in different positions.
Fig. 4 is a side elevation, and
Fig. 5 a plan view of the hammer.
Fig. 6 is a rear elevation, and
Fig. 7 a front elevation of the locking bolt with its arms for acting upon the lever
which actuates the extractor mechanism.
Fig. 8 is a plan view, and
Fig. 9 an end elevation of the ejector proper.
Fig. 10 is an elevation, Fig. 11 a top plan view, and Fig. 12 a plan view of the
ander side, of a slight modification of the invention.
In these drawings my invention is illustrated as applied to a double-barrelled gun.
The ejector is of known construction and consists of a plate A A¹ fitting flush
nto a recess in the breech end of the barrels B, to the bores of which it conforms,
nd having in its outer surface a recess a to receive the head or rim of the cartridge
se, as shown in Fig. 9.
This plate A, A' is capable of being moved away from the barrels, thus drawing
at the cartridge case with it.
When the barrels B are unlocked by releasing the locking bolt F in the usual
anner, the first movement of the barrels in order to open the breech causes a cam D
ig. 1) to force the ejector outward a short distance by acting upon a stem E
nnected with the ejector, thus forcing the cartridges slightly out from their seat
the chambers and making them ready to be ejected by the continued movement
the ejector when the barrels have been sufficiently opened.
The whole of the parts above described are of well known construction and
erate in the usual manner, and I have only described same in order to enable my
ention to be understood.
My invention consists in the following arrangement for effecting the further
ward movement of the ejector and so removing or ejecting the cartridge cases.

page_text: The rear end of the locking bolt F is provided with an arm G, G₁ situated
between two cheeks H', H2 of a pivoted lever H, one end of which (H³) is
connected to a slide or bar I. The end of the lever H, between the cheeks H', H2
of which such arm G is situated, is made in the form of a spring and constitutes
one cheek, to which the opposite cheek is connected by a cross piece / passing over
the locking bolt arm G, sufficient space being left between the checks H', H² to
receive the arm G and allow a certain clearance. The arm G is provided with a
notch g, and in its normal position the second named cheek H2 of the pivotted
lever H engages such notch, so that the movement of the locking bolt F will cause
the lever H to turn on its pivot.
When the hammer J of the gun is cocked, a projection J¹ thereon bears on the
side of the spring arm of the lever Hand forces it towards the locking bolt arm G,
whereby the other cheek H2 of the lever is removed from the notch g in such arm G,
and consequently the movement of the locking bolt F will not actuate the lever H,
whereas when the hammer J has fallen the projection J¹ thereon ceases to bear on
the spring arm of the lever H, and consequently the cheek H2 of the latter will
engage the notch 9 in the locking bolt arm G, and the movement of the bolt F will
consequently actuate the lever H as described. This action will be clearly understood
by referring to Figs. 6 and 7 of the drawings in each of which one side shows the
position of the parts when the hammer on that side has been discharged and the other
side the position when the hammer on that side is cocked. As the movement of
lever H is utilized to effect the further movement of the ejector A, A', it will be
seen that unless the bammer J has fallen the action of opening the barrels will not
effect the ejection of the cartridge.
The movement of the upper end of lever H causes the plate or slide I connected to
the opposite end thereof to be moved into the position shown in Fig. 3, so that the
action of opening the barrels will cause such slide I to act upon a sear or catch K
and release it from a notch in a spring bolt L, and such bolt being thus released
is suddenly shot forward by its spring M and acts upon the stem E of the
ejector A, A', forcing it also suddenly forward to its full extent, thereby ejecting the
. cartridge cases.
The movement of closing the gun compresses the spring bolt L again and causes
the sear K to retain it, and the locking bolt F returning to its normal position to
lock the barrels (carrying with it its arin G and consequently the lever H and slide I
if same have been actuated during the previous movement) the parts will all be
returned to their normal position and retained there until the locking bolt F is again
actuated by its hand lever X, when, (if the hammer J has previously fallen) its
movement is transmitted as above described through the pivotted lever H to the
slide I which acts upon the sear K.
In the modification shown in Figs. 10, 11 and 12, instead of making the end H
of lever H in spring form, and with two cheeks H1, H2, (as above described) such
lever is made rigid and its upper end H is plain and permanently engages the
arm G of locking bolt F, while its lower end engages the slide I when the hammer J
is in the discharged position. The end of slide with which the lower end of lever H
engages is made in the form of a spring and when the hammer J is cocked the
projection J thereon bears upon such end and forces it away from the end of
lever H, so that the latter no longer engages same, and consequently the movement
of the locking bolt F and of lever H will no longer be transmitted to slide 1, and
the ejector mechanism will consequently not be actuated.
Instead of the end of slide I being made of spring form and the projection J of
hammer J being caused to bear thereon when the hammer is cocked, the slide may
be made rigid and the lower end of lever H be of spring form, the projection J' of
hammer J being in this case so situated as to bear upon such lower end of lever H
when the hammer is cocked, thus producing the same result as in the former case.
The drawings show the invention as applied to double barrelled drop down guns,
the locking bolt F being provided with two arms G, G₁, and the other parts being
duplicated, so that the ejector mechanism for each barrel will act independently of

page_text: the other, and consequently if only one barrel has been discharged, the case of the
discharged cartridge will be ejected when the gun is opened, without ejecting the
cartridge from the other barrel.
For a single barrelled gun a single set only of the parts described will be provided,
and their action will be identical with that of either half of a double barrelled gun,
as above described.
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 improved means for actuating the ejector consisting of a lever, which is
operated by the backward movement of the locking bolt in the action of unlocking
the barrels, and moves a sliding part into such a position that the drop down
movement of the barrels will bring it into contact with a retaining devico serving to
hold back the ejector mechanism, and thus cause the latter to be released and effect
the ejection, substantially as specified.
2. The combination with the arm G on the rear of the locking bolt F, lever H and slide I,
of a projection J¹ formed on the hammer J in such a position as to bear upon either the
lever or the slide, the part on which such projection bears being in the form of a
spring, so that the projection will disconnect the parts and prevent the movement of
the locking bolt from being transmitted to the ejecting mechanism, except when the
hammer has been caused to fall, substantially as specified.
3. The combination of parts described for effecting the ejection of cartridges from
the barrels of drop down guns, by the action of opening the barrels when the
hammers are in the uncocked position, substantially as specified.
