We, HENRY WILLIAM HOLLAND, of 28, Maida Vale, and THOMAS WOODWARD,
of 69, Ashburnham Road, both in the County of Middlesex, Gun Makers, do
hereby declare the nature of this invention to be as follows:-
This invention relates to double barrelled single trigger guns.
Various devices have before been proposed to prevent the premature discharge
of the second barrel by the involuntary pull of the trigger caused by the recoil
from the first discharge.
In some of such guns a slide carried by the trigger has had two lugs upon it-
one of which in one position of the slide came beneath the tail end of the sear
of the right hand lock so that this scar would be tripped when the trigger was
pulled whilst in its other position the other lug would be below the tail end of
the sear of the left hand lock and the left hand barrel could then be fired.
The slide has also been so made as to require a considerable length of travel
to shift from one of its positions to the other to accomplish the above object.
According to our present invention we carry the two studs or lugs upon a
swinging quadrant pivotted to the upper part of an upward extension of the rear
end of the trigger.
The quadrant is slotted vertically and the upward extension of the trigger
enters this slot so that one side of the quadrant comes on one side of the extension
and the other on the other side.
One side carries the stud or lug for acting on the sear of the right hand lock
and the other the stud or lug for acting on the sear of the left hand lock.
From one side also extends a pin acted on by a spring which tends to turn
the quadrant into position to allow of the second or left hand barrel being fired.
Each time that the gun is closed a downward projection from the ordinary
safety bolt may (as this bolt is moved back into its "safety position) act upon
the upper end of the quadrant and turn the quadrant into position to bring the
lug on the right hand side of the quadrant below the tail end of the sear of the
right hand lock. This downward projection from the safety bolt at the same
time coming above the top of the upward projection of the trigger and locking
the trigger from being pulled. A stop on the quadrant also at the same time
comes in front of the tail end of the sear so that when the safety bolt is again
pushed forwards to put it out of action the quadrant remains in the position
into which it was turned.
The right hand barrel would therefore he fired on the trigger being pulled
and when the trigger has returned to its normal position the quadrant would
be turned by its spring into its second position to bring the stud or lug on its
left hand side into position for acting on the sear of the left hand lock.

page_text: The quadrant is at this time free to be thus turned as the lock is so formed
that when the hammer has fallen the tail end of the sear does not return to the
position from which it was lifted.
As there may be a very considerable length of are between the one stud or lug
carried on one side of the quadrant and the stud or lug carried on the other side
any secondary pull given to the trigger will have been given before the quadrant
has had time to turn from the oue position to the other.
In place of the swinging quadrant being acted upon by the safety bolt as above
described it might be similarly acted on by the hammer of one of the locks or
by a connection from the action bolt.
In place also of the swinging quadrant itself carrying the lugs or studs for
acting on the sears it might act upon a slide carrying such lugs or studs.
The swinging quadrant might also if preferred be otherwise carried so long
as it is free to be turned into two positions and also to be raised when the trigger
is pulled.

We, HENRY WILLIAM HOLLAND, of 28, Maida Vale, and THOMAS WOODWARD.
of 69, Ashburnham Road, both in the County of Middlesex, Gun Makers, 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 double barrelled single trigger guns.
Various devices have before been proposed to prevent the premature discharge
of the second barrel by the involuntary pull of the trigger caused by the recoil
from the first discharge.
In some of such guns a slide carried by the trigger has had two lugs upon it-
one of which in one position of the slide came beneath the tail end of the sear
of the right hand lock so that this sear would be tripped when the trigger was
pulled whilst in its other position the other lug would be below the tail end of
the sear of the left hand lock and the left hand barrel could then be fired.
The slide has also been so made as to require a considerable length of travel
to shift from one of its positions to the other to accomplish the above object.
In other cases the two lugs have been upon a swinging plate or rocker pivoted
in various ways to the trigger. It has also been proposed to carry the two studs
or lugs on a swinging quadrant pivoted to a pin fixed to the lock frame.
According to our present invention we carry the two studs or lugs upon a
swinging quadrant pivotted to the upper part of an upward extension of the rear
end of the trigger.
The quadrant is slotted vertically and the upward extension of the trigger
enters this slot so that one side of the quadrant comes on one side of the extension
and the other on the other side.
One side carries the stud or lug for acting on the sear of the right hand lock
and the other the stud or lug for acting on the sear of the left hand lock.
From one side also extends a pin acted on by a spring which tends to turn
the quadrant into position to allow of the second or left hand barrel being fired.

page_text: Each time that the gun is closed a downward projection from the ordinary
safety bolt may (as this bolt is moved back into its "safety" position) act upon
the upper end of the quadrant and turn the quadrant into position to bring the
lug on the right hand side of the quadrant below the tail end of the sear of the
right hand lock. This downward projection from the safety bolt at the same
time coming above the top of the upward projection of the trigger and locking
the trigger from being pulled. A stop ou the quadrant also at the same time
comes in front of the tail end of the sear so that when the safety bolt is again
pushed forwards to put it out of action the quadrant remains in the position
into which it was turned.
The right hand barrel would therefore be fired on the trigger being pulled
and when the trigger has returned to its normal position the quadrant would
be turned by its spring into its second position to bring the stud or lug on its.
left hand side into position for acting on the sear of the left hand lock.
The quadrant is at this time free to be thus turned as the lock is so formed
that when the hammer has fallen the tail end of the sear does not return to the
position from which it was lifted.
As there may be a very considerable length of are between the one stud or lug
carried on one side of the quadrant and the stud or lug carried on the other side
any secondary pull given to the trigger will have been given before the quadrant
has had time to turn from the one position to the other.
The drawings annexed illustrate the above improvements.
Figure 1 is a view of the parts in the positions in which they are after the
gun has been opened and closed-the view is taken from the right hand side
the locks being removed.
Figure is a similar view shewing the safety bolt pressed forward and put
out of action the parts are now in position to allow of the right hand barrel
being fired.
Figure 3 is a similar view after the right hand barrel has been fired and the
parts have come into position ready for firing the left hand barrel.
Figure 4 is a view taken from the left hand side when the parts are in the
position shewn in Figure 2.
Figure 5 is a similar view when the parts are in the position shewn in Figure 3.
Figures shew various views of the swinging quadrant carried by the trigger.
A is an upward extension of the rear end of the trigger. B the swinging
quadrant jointed to the upper end of the extension and slotted so that one side
of it may come on one side of the extension and the other on the other.
C is a spring tending always to turn the quadrant rearwards.
B is the stud or lug on the quadrant for acting upon the extremities D) of the
sear or sears of the right hand lock and B the stud or lug on the opposite side
of the quadrant for acting upon the extremities of the sear or sears of the
left hand lock.
'
Fis the safety bolt which when slid rearwards turns the quadrant B into the
position shewn in Figure 1. When the safety bolt is pressed forwards to put
it out of action the spring C turns the quadrant B until it is arrested by the
shoulder B upon it coming against the side of one of the sears D as shewn in
Figure 2.
When the trigger has been pulled and the right hand barrel fired the foremost
of the sears D is by the formation of the lock kept from descending again to its
former position so that the spring can turn the quadrant freely rearwards and
bring it into the position shewn in Figure 3 the quadrant itself being cut away
in such manner that the end of the rearmost sear does not interfere with its
movement
In place of the swinging quadrant being acted upon by the safety bolt as above
described it might be similarly acted on by the hammer of one of the locks or
by a connection from the action bolt.

page_text: In place also of the swinging quadrant itself carrying the lugs or studs for
acting on the sears it might act upon a slide carrying such lugs or studs.
The swinging quadrant might also if preferred be otherwise pivotted at the top
to the trigger, so long as it is free to be turned into two positions and also to be
raised when the trigger is pulled.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The employment of a swinging quadrant pivotted at the top to the trigger
and acting substantially in the manner herein before described.
2. Single trigger mechanism for double barrelled guns arranged substantially
as herein before described and illustrated in the drawings annexed.
Dated this 26th day of August 1898.
