COMPLETE SPECIFICATION.
Improvements in Double Barrel Guns having One Trigger.
I, SETH JOHN WALLIS, of 156 High Street, Lincoln, in the County of
Lincoln, Gun Maker, do hereby declare the nature of my said 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 my invention is improvements in double barrel guns having one
trigger such as those described in my Patent No. 1917 A.D. 1872 by which I render
such guns more certain in action and whereby either barrel can be fired at the
option of the shooter without the operation of any mechanism except the pulling of
the trigger while at the same time I make such provision for indicating which barrel
has been fired, that it can readily be seen at a glance.

page_text: In carrying my invention into effect I form a trigger block in which I pivot the
finger part of the trigger which is so shaped and pivotted that it can be pulled
either in an upward direction or in a downward direction. The levers for
operating the scears are separate from the trigger and are each so shaped with an
arm which runs down into the trigger block so that as the trigger is pulled down-
wards it operates a nose on the one or longer arm and when pulled upwards a nose
on the other or shorter arm thus operating one or the other of the scears as the case
may be this being effected by reason of these intermediate levers being cranked,
shaped, and so pivotted that the other part of the crank operates on the under-side
of the scears and thus releases the tumblers when the nose part of either of the
crank levers is operated by the trigger.
To indicate which side has been fired I mount a finger upon the arbor of each
tumbler which finger is formed in a recess in the outside plates each side the action
and these fingers turn with the tumblers thus indicating which side has been fired.
In place of having the trigger shaped and pivotted I may mount two studs push
or pull studs in the trigger block which when pulled direct would operate on one
or the other of the crank levers as the case may be each being provided with either
a rounded or circular end to fit the finger and a spring to bring them back after
being depressed.
In order that my invention may be clearly understood and more easily carried
into practise I have appended hereunto a double sized sheet of drawings upon
which I have fully illustrated the nature of my said improvements.
Figure 1., is a longitudinal section through the trigger block of my gun showing
the trigger and lever for one barrel.
Figure 2., is a similar section but showing the trigger and lever for the other
barrel.
Figure 3., is a similar section showing a modification in the form of trigger.
In carrying my invention into effect I form a trigger block F in which I pivot
the finger part of the trigger A at a', the trigger A being so shaped and pivotted
at a' that it can be pulled either in an upward direction as shown by the arrow a³
or in a downward direction as shown by the arrow a³. The levers E and E' for
operating the sears H are separate from the trigger A and are so shaped with the
arms e and e which run down the trigger blocks F so that as the trigger A is pulled
downwards it operates the nose et on the one or longer arm and when pulled
upwards the nose on the other or shorter arm e² thus operating one or the other
of the sears H as the case may be this being effected by reason of these inter-
mediate levers being cranked, shaped, and pivotted at so that the other part of the
crank operates on the underside of the sears H and thus releases the tumblers when
the nose parts e¹ or es of either of the crank levers E or E¹ are operated by the
trigger.
To indicate which side has been fired I mount a finger upon the arbor of each
tumbler which finger is formed in a recess in the outside plates each side the action
and these fingers turn with the tumblers thus indicating which side has been fired.
In place of having the trigger shaped and pivoted I may mount two push and
pull studs K and K in the trigger block F which when pulled direct operate on
one or the other of the crank levers as the case may be each being provided with
a rounded or circular end to fit the finger and a spring k³ to bring them back
after being so depressed.
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 :-
1st. In double barrel guns the single trigger A and levers E E¹ mounted and
operated substantially such as and for the purpose herein set forth and shown upon
the accompanying drawings.
2nd. In double barrel guns, the studs K K¹ and levers ee mounted and operated,

page_text: substantially such as and for the purpose herein set forth and shown upon the
accompanying drawings.
Dated this 19th day of September 1893.
