page_text: 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, my object being to provide simple and effective means whereby either
barrel can be discharged by the action of the one trigger.
In carrying my invention into effect in one manner I pivot upon the blade or
inner part of the single trigger a small bell crank lever, the short arm of which
is arranged for engagement by a slide supported on the inner side of the trigger
plato. The forward end of the said slide is caused to abut against a lever pivotted
upon the action and so shaped that on the opening of the gun the said lever is
operated or moved by the ordinary action bolt in the direction necessary to force
back the slide. By such movement of the slide engaging the short arm of the
hereinbefore described bell crank lever on the trigger, the free end of the long
arm of the lever is carried under the ordinary and safety sears of the right hand
lock, and retained at such position by the engagement or abutment of a vertical
projection from an extension of the slide with the back end of the safety sear.
On then closing the gun the trigger is in connection for firing the right hand
barrel.
After firing the right hand barrel the trigger returns to its normal position.
and a projection from the trigger blade which previously engaged with and
retained the slide, (independently of the engagement of the slide extension pro-
jection with the safety sear as herein before described), is disengaged, and the slide
is then urged forward by the action of a spring at its rear end until temporarily
arrested by the back end of the trigger blade to prevent accidental firing of the
left hand barrel. By the recoil due to firing a second or involuntary pull is
imparted to the trigger which releases the slide and allows it to complete its
forward movement thereby operating the bell crank lever and thus putting the
trigger into connection with the left hand lock mechanism.
On opening the gun after firing either the right or left hand barrel the trigger
is always placed into connection with the right hand lock mechanism, and the
bell crank lever mounted on the trigger is retained in its proper position for such
connection by means of a suitably formed and attached spring.
To enable the shooter to disconnect the trigger from the right hand lock
mechanism without discharging the right hand barrel, a pin or spindle of an
angular section is mounted upon the right hand lock plate over the safety sear,

page_text: the outer end of such pin or spindle being provided with a finger or grip piece
for turning or revolving it sufficiently to lift the safety sear out of engagement
with the projection from the slide extension herein before described. The slide,
when thus released is urged forward by its spring in a like manner as on the
release effected by the return of the trigger to its normal position after firing.
I sometimes dispense with the use of a slide such as hereinbefore described
and utilise in its stead the ordinary top or safety slide employed with drop down
guns. In opening a gun in which the safety slide is so employed the said slide
presses against the short arm of a lever, pivotted vertically upon a specially
formed trigger or trigger blade, and, carries the long arm under the scars of the
right hand lock mechanism, in which position it is retained by means of a small
spring mounted on the trigger plate. The trigger is so shaped and pivotted
upon the ordinary breech pin box that on raising it for the purpose of firing the
gun, the portion of the trigger immediately above the inner side of the trigger
plate so lengthens as it rises that on the release of the long arm of the lever,
due to the movement of the trigger, from one portion of a retaining spring
mounted in the trigger plate, a lateral projection from the long arm abuts against
the upper portion of the retaining spring and prevents further movement until
the trigger returns to its normal position. On such return movement the lateral
projection moves away and becomes released from the retaining spring thus
permitting of a further movement of the lever (under the impulse imparted by its
own spring) to a position at which it is again locked or held by the retaining
spring, until the trigger is raised by the involuntary pull which completes the
movement of the lever necessary to put the trigger into engagement with the
other lock mechanism.
To enable the shooter to disconnect the trigger from the right hand lock
mechanism, without discharging the right hand barrel, in a gun having the safely
slide arranged to operate the trigger connecting mechanism as hereinbefore
described, I mount a sliding finger piece upon the trigger plate in such a position
that when moved in the required direction it engages with and depresses the
retaining spring hereinbefore described. With the retaining spring so depressed
the lever mounted on the trigger will be returned towards the left hand lock
mechanism by the impulse of its own spring.
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 and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:―
This invention consists of improvements relating to double barrel drop down
guns, my object being to provide simple and effective means whereby either
barrel can be discharged by the action of the one trigger.
In the two accompanying sheets of explanatory drawings to be hereinafter
referred to:

page_text: Figure 1 on Sheet 1 is a side elevation of a portion of a double barrel drop
down gun fitted with my single trigger mechanism, the left hand lock plate being
omitted.
Figure 2 is a plan of a portion of the trigger plate with the improved mechanism
thereon.
Figure 3 is a side elevation and Figure 4 an end elevation of the trigger
engaging or connecting piece which is pivotted upon the trigger blade.
Figure 5 is a side elevation and Figure 6 an end elevation of the trigger.
Figure 7 is a plan, and Figure 8 a sectional end elevation on the line a b
Figure 7, of the engaging piece operating slide.
On Sheet 2, Figure 9 is a side elevation. with part in section, showing another
form of my trigger engaging or connecting piece pivotted vertically upon the
trigger blade. Figures 10, 11, and 12, are end elevations showing three different
positions of the said engaging or connecting piece.
Figure 13 is an end elevation and Figure 14 a side elevation showing the
engaging or connecting piece separately; Figure 15 is a side elevation and
Figure 16 an end elevation of the trigger.
The same reference letters in the different views indicate the same parts.-
In carrying my invention into effect as illustrated on Sheet 1 of the drawings,
I pivot upon the blade or inner part of the single trigger A an engaging or con-
necting piece consisting preferably of a small bell crank lever as B, the short
arm of which is arranged for receiving motion from a slide C supported on the
inner side of the trigger plate D. The forward end of the said slide C is caused
to abut against a lever E pivotted upon the action and so shaped that on the
opening of the gun the said lever E is operated or moved by the ordinary action
bolt F, in the direction indicated by the arrow at Figure 1, to force back the
slide C. By such movement of the slide C which engages the short arm of the
herein before described bell crank lever B on the trigger, the free end of the long
arm of the lever is carried under the ordinary and safety sears of the right hand
lock, and retained at such position by the engagement or abutment of a vertical
projection C from an extension of the slide C, with the back end of the safety sear.
On then closing the gun the trigger is in connection for firing the right hand
barrel.
After firing the right hand barrel the trigger returns to its normal position,
and a projection A¹ from the trigger blade which previously engaged with and
retained the slide C, (independently of the engagement of the slide extension
projection C with the safety sear as hereinbefore described), is thereby dis-
engaged the slide is then urged forward by the action of a spring G at its rear
end until temporarily arrested by the stop piece As at the back end of the trigger
blade to prevent accidental firing of the left hand barrel. By the recoil due to
firing a second or involuntary pull is imparted to the trigger which releases the
slide and allows it to complete its forward movement thereby operating the bell
crank lever and thus putting the trigger into connection with the left hand lock
mechanism.
On opening the gun after firing either the right or left hand barrel the trigger
is always placed into connection with the right hand lock mechanism, and the
bell crank lever mounted on the trigger is retained in its proper position for such
connection by means of a suitably formed and attached spring as H.
To enable the shooter to disconnect the trigger from the right hand lock
mechanism without discharging the right hand barrel, a pin or spindle of an
angular section is mounted upon the right hand lock plate over the safety sear, the
outer end of such pin or spindle being provided with a finger or grip piece for
turning or revolving it sufficiently to lift the safety sear out of engagement with
the projection C from the slide extension herein before described. The slide C,
when thus released, is urged forward by its spring G in a like manner as on the
release effected by the return of the trigger to its normal position after firing.
I sometimes dispense with the use of a slide C such as hereinbefore described

page_text: and utilise in its stead the ordinary top or safety slide J employed with drop
down guns, in combination with which I arrange special mechanism as herein-
after described and as illustrated on Sheet 2 of the accompanying drawings. In
opening a gun in which the safety slide is so employed in accordance with my
present invention, the said slide presses against the short arm of a lever K,
(which constitutes the trigger engaging or connecting piece), pivotted vertically
upon a trigger A having a specially formed blade, and carries the long arm of
such lever under the sears of the right hand lock mechanism, in which position
it is retained against the action of a spring as L mounted on the trigger blade,
by means of the abutment piece or retaining spring hereinafter described. The
trigger A is so shaped and pivotted upon the ordinary breech pin box M that on
pulling it for the purpose of firing the right hand barrel of the gun, the trigger
blade, or the portion immediately above the inner side of the trigger plate D¹;
is so raised that the edge of the lower end of the long arm of the lever K is
released from its engagement position (shown at Figures 9 and 10) with the
retaining spring N mounted on the trigger plate D¹. On such release the lower
end of the long arm of the lever K moves laterally in the direction indicated by the
arrow at Figure 10 until arrested by a lateral projection from the long arm,
which abuts against the upper portion of the retaining spring N and prevents
further movement until the trigger drops to its normal position. On such return
movement the lateral projection k moves away and becomes released from the
retaining spring N thus permitting of a further movement of the lever K, (under
the impulse imparted by its own spring L), to the position indicated at Figure 11
where it is again checked or held by the retaining spring N, until the trigger is
raised by the involuntary pull which releases the lever and permits of the com-
pletion of its lateral movement (indicated at Figure 12) necessary to put the
trigger into engagement with the other lock mechanism."
To enable the shooter to disconnect the trigger from the right hand lock
mechanism, without discharging the right hand barrel, in a gun having the safety
slide arranged to operate the trigger connecting mechanism as herein before
described and as illustrated on Sheet 2 of the drawings, I mount a sliding finger
piece upon the trigger plate in such a position that when moved in the required
direction it engages with and depresses the aforesaid retaining spring N. With
the retaining spring so depressed the lever K mounted on the trigger will be
returned towards the left hand lock mechanism by the impulse of its own spring L.
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, operating the
trigger engaging or connecting piece by the movement of the ordinary action
bolt on the opening of the gun, substantially as described.
2. In double barrel drop down guns having a single trigger, the combination
with a bell crank lever as B, pivotted on the trigger blade, and with the action
bolt F, of the slide C provided with a spring as G, and of the lever E, substan-
tially as and for the purposes described and as illustrated.
3. In a single trigger double barrel gun having a slide as C transmitting
motion to the trigger engaging or connecting piece B, means for checking or
controlling the forward movement of the said slide C imparted by the action of
the spring G, substantially as and for the purpose described and as illustrated.
4. The arrangement and combination with the top or safety slide and with the
single trigger of a double barrel drop down gun, of an engaging or connecting
piece consisting of a lever such as K pivotted vertically upon the blade of the said
trigger, substantially as described and as illustrated.
5. In a double barrel drop down gun having a single trigger on which is
pivotted an engaging or connecting piece consisting of a lever as K claimed in the
preceding claim, checking or controlling the movement of the long arm of the

page_text: said lever imparted by the action of a spring L, substantially as described and as
illustrated.
6. In double barrel drop down guns, the general arrangement and combination
of parts comprising and relating to the single trigger mechanism, substantially
as described and as illustrated.
