Improvements relating to Double Barrel Drop Down Guns.
I, WILLIAM HENRY BRIGHTON, of Beatrice House, Jockey Road, Wylde Green,
in the County of Warwick, Gun Action Maker, do hereby declare the nature of
this invention to be as follows:-
This invention consists of improvements relating to double barrel drop down
guns of side lock and other types, my object being to construct and arrange
simple and reliable mechanism for enabling the two barrels to be discharged
by the action of a single trigger.
In one application of my invention I employ a pair of lock plates each of
which has a hammer or tumbler with sears, bridle, springs, and other ordinary
parts mounted on its inner side. The single trigger is pivotted upon the breech
pin box forming a part of the trigger plate, and upon or in connection with its
inner portion, or the trigger blade, I mount and arrange special mechanism such
as hereinafter described.
On a projecting arm from the breech pin box I pivot a lever having a short
arm engaging with the ordinary top slide, and a long arm which engages with a
racked slide piece carried by the trigger blade, the teeth of the rack being made
to gear with similar teeth formed on a sector or engaging piece horizontally
pivotted upon the trigger blade.
On operating the top lever and opening the gun, the movement of top slide
forces back the short arm of the lever, hereinbefore described, and thus carries
forward the long arm of the said lever and with it the racked slide piece. By
such movement of the slide piece the sector or engaging piece is turned on its axis
and caused to pass under the safety sear of the right hand lock of the gun, and
to engage with and be fixed by the tail of the said safety sear. On then pulling
and releasing the trigger, after the loading and closing of the gun, the fall of
the right hand tumbler or hammer raises the tail end of the safety sear and thus
releases the sector or pivotted engaging piece. Immediately on such release the
action of a spring, suitably arranged with the lever having the long and short
arms, draws back the racked slide piece, and the sector or pivotted engaging
piece is thereby revolved until it is brought into engagement with the sears of
the left hand lock. The trigger is thus put into connection with the left hand
lock so that on again pulling the trigger the left hand barrel will be discharged.
After the fall of the left hand tumbler the opening of the gun will cause the
trigger to be again put into connection with the right hand lock mechanism.
The spring arranged in connection with the racked slide piece operating lever
tends to constantly maintain the trigger in connection with the left hand lock
mechanism, but by the opening movement of the gun the action of the spring is
overcome and the trigger is put into connection with the right hand lock mechan-
ism and is retained in such connection until the discharge of the right hand
barrel, as hereinbefore described.

page_text: For the purpose of enabling the sportsman or user of the gun, to disconnect
the trigger from the right hand lock mechanism without operating the trigger
for the discharge of the right hand barrel, I provide a semi-circular or angular
shaped pin or spindle, mounting it upon the right hand lock plate immediately
above the safety sear. On the outside of the lock plate I form with the pin or
spindle an operating thumb or finger piece, by means of which the pin or spindle
can be revolved sufficiently to depress the safety sear and thus cause its tail to
be lifted out of engagement with the sector or pivotted engaging
piece hereinbefore described. The sector or engaging piece being thus
released, the action of the spring on the racked slide operating lever will
be permitted to force back the slide and thus revolve the sector until it is brought
into engagement with the sears of the left hand lock mechanism. By such dis-
connecting arrangement the gun can be readily set for firing with one barrel
only, as the engagement and locking or fixing of the sector or pivotted engaging
piece against the action of the spring of the slide operating lever, as herein-
before described, will be prevented after the pin or spindle has been set at the
disengaging position by the simple movement of the thumb or finger piece in
the required direction. On operating the thumb or finger piece in the reverse
direction the disconnecting pin or spindle is placed out of action.

Ímprovements relating to Double Barrel Drop Down Guns.
I, WILLIAM HENRY BRIGHTON, of Beatrice House, Jockey Road, Wylde Green,
in the County of Warwick, Gun Action 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 consists of improvements relating to double barrel drop down
guns of side lock and other types, my object being to construct and arrange
simple and reliable mechanism for enabling the two barrels to be discharged by
the action of a single trigger.
In the two accompanying sheets of explanatory drawings to be hereinafter
referred to.-
Figure 1 on Sheet 1 is a side elevation of a portion of a double barrel drop down
gun fitted with my improved single trigger mechanism, the left hand lock plate
being omitted in the figure.
Figure 2 is a plan of a portion of the trigger plate showing the improved
mechanism.
Figure 3 is a side elevation and Figure 4 an end elevation of the trigger.
Figure 5 is a side elevation and Figure 6 an end elevation of the racked slide
piece.
Figure 7 is a plan and Figure 8 a side elevation of the sector with which the
racked slide piece engages.
On Sheet 2 Figure 9 is an elevation of the inner side of the right hand lock
plate of the gun fitted with means for the disconnection of the right hand lock
imechanism from the trigger.

page_text: Figure 10 is a plan of the lock plate, and Figure 11 an elevation of its outer
side.
The same reference letters in the different views indicate the same parts.-
In the application of my invention as illustrated by the drawings, I employ
a pair of lock plates each of which has a hammer or tumbler with sears, bridle,
springs, and other ordinary parts mounted on its inner side. The single trigger A
is pivotted upon the breech pin box B' forming a part of the trigger plate B,
and upon or in connection with its inner portion, or the trigger blade A¹, I
mount and arrange special mechanism such as hereinafter described.
On a projecting arm B3 from the breech pin box B₁ I pivot a lever C having a
short arm engaging with the ordinary top slide D, and a long arm which engages
with a racked slide piece. E carried by the trigger blade A¹, the teeth of the
rack being made to gear with similar teeth formed on a sector or engaging or
connecting piece F horizontally pivotted upon the trigger blade.
On operating the top lever G and opening the gun, the movement of the top
slide 1 forces back the short arm of the lever C, herein before described, and
thus carries forward (in the direction indicated by the arrows at Figures 1 and 2)
the long arm of the lever C and with it the racked slide piece E. By such move-
ment of the slide piece the sector or engaging piece F is turned on its axis and
caused to pass under the safety sear of the right hand lock of the gun, and to
engage with and be fixed by the tail of the said safety sear. On then pulling
and releasing the trigger after the lowering and closing of the gun, the fall of
the right hand tumbler or hammer raises the tail end of the safety sear and thus
releases the sector or pivotted engaging piece. Immediately on such release the
action of a spring as H suitably arranged with the lever C draws back the racked
slide piece E, and the sector or pivotting engaging piece F is thereby revolved
until it is brought into engagement with the sears of the left hand lock. The
trigger is thus put into connection with the left hand lock so that on again pull-
ing the trigger the left hand barrel will be discharged.
After the fall of the left hand tumbler the opening of the gun will cause the
trigger to be again put into connection with the right hand lock mechanism.
The spring as H arranged in connection with the racked slide piece operating
lever C tends to constantly maintain the trigger in connection with the left hand
lock mechanism, but by the opening movement of the gun the action of the
spring is overcome and the trigger is put into connection with the right hand
lock mechanism and is retained in such connection until the discharge of the
right hand barrel, as hereinbefore described.
For the purpose of enabling the sportsman or user of the gun, to disconnect
the trigger from the right hand lock mechanism without operating the trigger
for the discharge of the right hand barrel, I provide a semi-circular or angular
shaped pin or spindle as J, (Figures 9 and 10 Sheet 2) mounting it upon the
right hand lock plate immediately above the safety sear. On the outside of the
lock plate I form with the pin or spindle an operating thumb or finger piece J¹,
(Figure 11) by means of which the pin or spindle can be revolved sufficiently
to depress the safety sear (as indicated by dotted lines at Figure 9) and thus
cause its tail to be lifted out of engagement with the sector or pivotted engaging
piece herein before described. The sector or engaging piece being thus released,
the action of the spring on the racked slide operating lever will be permitted to
force back the slide and thus revolve the sector until it is brought into engagement
with the sears of the left hand lock mechanism. By such disconnecting arrange-
ment the gun can be readily set for firing with one barrel only, as the engagement
and locking or fixing of the sector or pivotted engaging piece against the action
of the spring of the slide operating lever, as herein before described, will be
prevented after the pin or spindle has been set at the disengaging position by
the simple movement of the thumb or finger piece in the required direction. On
operating the thumb or finger piece in the reverse direction the disconnecting
pin or spindle is placed out of action.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
-
1. In double barrel drop down guns having a single trigger, the combination
with the said trigger of an engaging or connecting piece as F rotatable beneath
the sears of both the right and left hand locks, substantially as and for the pur-
pose described and as illustrated.
