PROVISIONAL SPECIFICATION.
Improvements in the Ejector Mechanism of Drop-down Guns.
I, CHARLES HENRY MALEHAM Westbar, Sheffield, in the County of York Gun-
maker, do hereby declare this invention to be as follows:-
The object of the invention is to simplify the mechanism, and to avoid engaging
the "
sear or rocking catch with the ejector rod, until after the gun is fired.
""
In carrying out the invention, 1 construct the sear or rocking catch, of such a
form, and fix it in such a position that when the gun is fired, the cocking lever (or
an attachment thereto) is forced forward by the hammer, and moves the sear or
rocking catch until it engages with the ejecting arm or rod, so as to retain it in
position, ready for service.
When the gun is opened and the barrels are dropped, a projecting portion of
the sear or rocking-catch, comes in contact with a fixed stud or nipple, projecting
from the body of the gun, which causes the sear or rocking shaft to turn upon its
axis and releases the ejector arm or rod

COMPLETE SPECIFICATION.
Improvements in the Ejector Mechanism of Drop-down Guns.
I, CHARLES HENRY MALEHAM Westbar, Sheffield, in the County of York, 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 :-
The object of this invention is to simplify the mechanism connected with the ejector,
and to avoid engaging the sear or rocking catch with the ejector rod until after the
gun is fired, and I accomplish this as shown in the annexed sheets of drawings in
which I illustrate several modifications, or equivalent arrangements; similar letters of
reference indicate similar parts in any of the figures.
Fig. 1, represents a side view and part of the end of the breech of a drop down
gun, made according to this invention.
Figs. 2 & 3, breech of drop down gun, closed and open, with modification of
mechanism.
Fig. 4, modification of mechanism to actuate the sear, with rocking lever.
Figs. 5 & 6, are two views showing my invention applied in a modified form to the
Anson Deeley lock.
In carrying out my invention as illustrated in Fig. 1, I fix the sear or rocking
catch A, upon a stud or axis having the same axial centre B, as that of the cocking
lever C, and projecting a sufficient distance to engage with the ejector D, when
required, in which position it is retained by a spring, such as E.
Through the projecting end of the cocking lever C, I fix a small trip lever F, having
a short movement upon its axis, which is seen in the end view, this movement is
caused by one end of the trip lever coming in contact with a fixed stop G.
When the gun is fired, the cocking lever C, is raised at its projecting end until

page_text: the sear A, engages with the ejector D, as shown; when the barrels are dropped and
reach the end of the movement, the trip lever F comes in contact with the stop G,
and its opposite end presses down and releases the sear from the ejector.
When the gun is cocked and closed, the projecting end of the cocking lever is
slightly depressed and thus prevents the sear engaging with the ejector; this depres-
sion may be effected by the action of a small spring such as H acting under the tail
of the cocking lever.
I obtain the same result by the arrangement illustrated in Figs. 2 & 3, in which I
fix a cranked sear A, upon a stud or axis having the same axial line B as that upon
which the barrels turn, the long upper arm being to engage with the ejector 1, the
lower arm being connected with a rod K, by means of a slot L made through the
rod, or by other means such as studs projecting from the side of the rod, or other
,device.
The said rod may be either the usual cocking rod or it may be a special rod in
. connection with the hammer, or with the main spring, or form a
spring.
part of the main
Although I have shown the rod K, connected with an arm of the sear underneath
the axis, it may be reversed in position, by being connected with the sear above its
axis, as indicated in dotted lines in Fig. 3, in which case the opposite end of the rod
would be, connected with the hammer below the axis. Until the gun is fired the sear
is kept out of contact with the ejector by its lower end coming in contact with the
front end of the slot L; after firing, the rod is pushed forward and permits the sear
to be raised by a spring so as to engage with the ejector.
The sear may also be retained out of contact with the ejector, by the arrangement
shown in Fig. 4, in which the hammer M, in cocking the gun raises the short end of
a lever N, causing the long end to press down the sear A, as shown; when the gun
is fired, the lever N is released, and the sear is free to be raised by the spring O,
into the ejector catch.
In Figs. 5 & 6, 1 illustrate a variation in the mechanical details which may be used
in adapting my invention to the Anson Deeley lock of a drop down gun; the sear A
projects from the front of the body, and turns as before described upon the same
axial centre B, as the barrels.
"
It is held in the "disengaged position shown in Fig. 6, by the arm P, which is
raised by the hammer M, when cocked, and when the gun is fired, as seen in Fig. 5,
it is raised to engage with the ejector by a spring Q.
To obtain this action in the contracted space available for the purpose, I pivot the
arm. P to the hammer M, raising it by means of a shoulder at R, but leaving it free
to move in the opposite direction.
When the gun
opened after being fired, the sear A retains the ejector until the
barrels are clear of the breech; the raised arm P then causes the sear to disengage
from the spring ejector which at once drives out the extractor and cartridge.
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-The combination with any arrangement of ejector mechanism for Drop-down
Guns, of a sear A, fixed upon, or turning upon an axis having the same centre line as
the axis upon which the barrels turn, substantially as shown in the annexed drawings.
2 The arrangement of ejector mechanism for Drop-down Guns, consisting of a
sear A, working on the same axial line as that upon which the barrels turn; a
-cocker C, provided with a trip lever F, stop G, and ejector D, working together sub-
stantially as herein before described and shown in Fig. 1.
3-The arrangement of ejector mechanism for Drop-down Guns, consisting of a
sear A, working on the same axial line as that of the axis on which the barrels turn,

page_text: in combination with a rod K, attached to or operated by the hammer M, directly or
indirectly, and an ejector D, working together substantially as hereinbefore described
and as shown in Figs. 2 & 3.
4-The combination of the sear A, lever N, spring O, and ejector D, arranged and
combined together for the purpose specified, and substantially as hereinbefore
described, and as shown in Fig. 4.
5 In the construction of ejector mechanism for Drop-down Guns, as shown in
Figs. 5 & 6 the arrangement and combination of the sear A, fixed on the same axial
line as that of the axis on which the barrels turn, with the arm P, the hammer M,
and ejector D, substantially as hereinbefore described.
