Improvements in or Connected with Breech Loading Sporting
Fire-arms.
I, EDGAR HARRISON of 142 New Bond Street, in the Parish of St. Georges,
Hanover Square, in the County of Middlesex, Gun Maker, do hereby declare the
nature of this invention to be as follows:-
My invention refers to sinple and effective means as hereafter described, for corking
the tumbler and ejecting the spent cartridge or empty shell at one and the same
time, in guns known as drop down sporting fire-arms
According to my invention I employ a lever fulcrummed in the fore part hereafter
called the fore part sear, and having only a small amount of movement about its
fulcrum, the forward arm of said forepart sear enga es or disengages as the case may
be, in a notch formed in the ejector leg, while the rear arm of said forepart sear is
acted on by the rod cam or lever used for cocking the tumbler or for compressing
the main springs.
On opening the gun after firing, the cocking rod lever or cam is pressed or kept
forward by the tumbler against the rear end of the forepart sear the forward end of
which forepart sear takes into the notch in the ejector leg, the forepart sear thus
having moved to its utmost becomes rigid with the fore part and presses or operates
the cocking rod lever or cam back on the tumbler thus placing same in the cocked
position. As soon as the tumbler is cocked the forepart sear comes in contact with
a stud, inclined plane, or projection, thus turning it upon its fulcrum and bringing
down the fore arm of the sear out of the notch in the ejector leg which thus released
springs backward so ejecting the cartridge, the gun now being opened to its utmost
extent.
On opening the gun while at full cock the pressure of the tumbler is removed
from the cocking mechanism, which latter would be operated by the forepart sear
without raising the forward end thereof which is kept down by a spring, and so the
ejector advances slowly on the opening of the gun and loosens, but does not eject, the
full cartridge.

Improvements in or Connected with Breech-loading Sporting
Fire-arms.
I, EDGAR HARRISON of 142, New Bond Street, in the Parish of St. Georges,
Hanover Square, 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:-
My invention refers to simple and effective means as hereafter described; for cocking
the tumbler and ejecting the spent cartridge or empty shell at one and the same time,
in guns known as drop down sporting fire-arms.
According to my invention 1 employ a lever fulcrummed in the fore part, hereafter
called the fore part sear, and having only a small amount of movement about its
fulcrum, the forward arm of said fore part sear engages or disengages as the case may
be, in a notch formed in the ejector leg, while the rear arm of said forepart scar is
acted on by the rod cam or lever used for cocking the tumbler or for compressing the

page_text: On opening the gun after firing, the cocking rod lever or cam is pressed or kept
forward by the tumbler against the rear end of the fore part sear the forward end of
which fore part sear takes into the notch in the ejector leg, the fore part sear thus
having moved to its utinost becomes rigid with the fore part and presses or operates
the cocking rod lever or cam back on the tumbler thus placing same in the cocked
position. As soon as the tumbler is cocked the fore part sear comes in contact with
a stud, inclined plane, or projection, thus turning it upon its fulcrum and bringing
down the fore arm of the sear out of the notch in the ejector leg, which thus released,
springs backward, so ejecting the cartridge, the gun now being opened to its utmost
extent.
On opening the gun while at full cock the pressure of the tumbler is removed from
the cocking mechanism, which latter would be operated by the fore part sear
without raising the forward end thereof which is kept down by a spring, and so the
ejector advances slowly on the opening of the gun and loosens, but does not eject, the
full cartridge.
And in order that my invention may be fully understood and readily carried into
effect I will now proceed to further describe same with reference to the accompanying
drawings.
Figure 1, is a sectional view of so much of a breech loading gun constructed
according to my invention, as will be necessary to explain one arrangement or modifica-
tion of same. Figure 2, a perspective view of the fore part sear and cocking lever
detached, drawn on a larger scale than Figure 1; Figure 3 shews my invention
combined with and applied to such a cocking action as that described in the specification
of "Perkes" patent, No. 1968 of 1878. Figure 4, shews a slight modification of my
invention as illustrated at Figure 1. Figure 5 shews the fore part sear A actuated at
its rear arm, and Figure 6 shews the fore part sear A which, in this modification, takes
into a notch in the ejecting tumbler F, instead of in the ejector leg itself.
fore part sear, B, the cocking lever or rod.
A, is the
Referring to Figures 1 and 2, A is the fore part sear which actuates and is actuated
by the cocking lever B. The fore end of this cocking lever B, engages with the fore
part sear A a short distance in front of the fulcrum of said sear. Similar ejectors
are used in my invention to those described by me in the specification of my
patent No. 16214 of 1886, having spiral springs situated at the fore end of the ejector
legs, for forcing out the ejectors.
On the opening of the gun after firing the fore end of the cocking lever B presses
against the fore end of the fore part sear A which it raises into the notch D' in
ejector leg D. The fore part sear A having turned to its utmost, becomes rigid, and
as the barrels are depressed the fore arm of the said sear depresses the fore arm of the
cocking lever B which lever in its turn cocks the tumbler. Just before the barrels
are fully opened the rear arm of the fore part sear A comes to the end of the slot E in
the action in which it travels which withdraws its fore end from the notch in the
ejector leg D, and the ejector being let go ejects the empty cartridge. In the case of
the gun not being fired the fore arm of the cocking lever B not bearing against the
fore arm of the fore part sear A the said fore part sear A would not engage with the
notch D in ejector leg D, so that the cartridge would be loosened but not
ejected.
In Figure 3, the rear arm of the fore part sear A is used to actuate the cocking
rod B. From this figure it will be clearly seen that when there is pressure on the
rod B, as there is after firing, the fore arm of the fore part sear A will rise into the
notch D' in the ejector leg 1), and if no pressure is on the rod B, then the fore arm
of the fore part sear A, will not rise into the ejector leg D, thus giving the same result
as before described.
Figure 4 is a slight modification of Figure 1, in which there are projections a and b
on the fore part sear A, and on the cocking lover B, respectively. On opening the
gun after firing, the centres of the fore part sear A, and the cocking lever B, being
drawn apart the projection a comes in contact with the projection 6, which thus lowers
the fore arm of the fore part sear A, and releases the ejector.

page_text: In Figure 5 the rear arm of the fore part sear takes into the notch D' in the ejector
leg on the opening of the gun after firing in which notch it remains until the part a of
the fore part sear A falls into the notch B' in the cocking lever B, which it does by
means of the spring A¹, when the gun is fully (or nearly so) opened and thus the spent
shell is ejected.
The spring A could be dispensed with in this arrangement by allowing the fore end
of the cocking lever B, to bear against the fore part sear A, a short distance in front
of the fulcrum of said sear A the pressure of said cocking lever B, having the same
effect as the spring A¹.
In Figure 6, the spring in front of the ejector leg is dispensed with and a tumbler F,
having a spring is used in its stead. On the opening of the gun after firing, the fore
part sear A, takes into the notch D¹ in the tumbler F. On the gun being fully opened
the said fore part sear A is withdrawn from the tumbler F by means of the slot E, at
the end of which it has arrived, thus freeing the tumbler suddenly which immediately
springs the ejector out and thus ejects the empty shell.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what I
claim, is :-
1st. The fore part sear A, in combination with the cocking lever or rod B,
substantially as and for the purposes set forth.
2nd. The cocking lever or rod B, together with the fore part sear A, spring A¹, and
slot E, by which means- the tumbler C, is cocked and the ejector leg D held, and then
let
go, all acting substantially as and for the purposes set forth.
3rd. The fore part sear A having a projection a, in combination with the
cocking lever B having a projection 6, substantially as described with reference to
Figure 4.
4th. The various arrangements shewn and described with reference to
Figures 1, 3, 4, 5 and 6, all substantially as and for the purposes set forth.
