PROVISIONAL SPECIFICATION.
Improvements in Double Barrel Guns having One Trigger.
I, SETH JOHN WALLIS, of 156 High Street, Lincoln, in the County of Lincoln,
Gunmaker, do hereby declare the nature of my said invention to be as follows: —
-
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 easier of manufacture and with improved
provision for the prevention of the accidental or unintentional discharge of both
barrels at the same time and to clearly indicate which side has been discharged
while the length of pull of the trigger is considerably reduced.
"
In carrying my invention into effect I form my trigger solid and provide a
ratchet wheel with ten teeth or notches and five arms to each sear releaser which
are all formed in one with the ratchet wheel. A female ratchet engages with the
ratchet wheel and is operated by a ratchet spring. A coiled or spiral trigger
spring is provided and placed in the rear end of block of trigger plate so as to
operate upon the one end of the trigger. An indicating disc is provided in lock
plate having two slots which expose words " on or "off"
as the case may be the
discs being counected with the arbor of the tumbler so that when on cock the top
slot will show the " on " and the "off" will be hid but upon either or both of the
locks being fired the tumbler will carry the disc round until the corresponding slot
will be at the bottom of lock plate thus showing which or if both of the barrels
have been fired. I also use an improved form of bolt in connection with the
above mechanism and my trigger is mounted in solid ears formed upon the trigger
plate.

COMPLETE SPECIFICATION.
Improvements in Double Barrel Guns having One Trigger.
I, SETH JOHN WALLIS of 156 High Street Lincoln, in the County of Lincoln,
Gunmaker, 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: -
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, easier of manufacture, and with improved
provision for the prevention of the accidental or intentional discharge of both
barrels at the same time and to clearly indicate which side has been discharged
while the length of pull of the trigger is considerably reduced.
In carrying my invention into effect I form my trigger solid and provide a
ratchet wheel with ten teeth or notches and five arms to each sear releaser which
are all formed in one with the ratchet wheel. A female ratchet engages with the
ratchet wheel and is operated by a ratchet spring. A coiled or spiral trigger
spring is provided and placed in the rear end of block of trigger plate so as to
operate upon the one end of the trigger. An indicating disc is provided in lock plate
having two slots which expose words "on" or "off" as the case may be the discs
being connected with the arbor of the tumbler so that when on cock the top slot
will show the "on," and the "off" will be hid but upon either of the locks being fired

bottom of lock plate thus showing which, or if both of the barrels have been fired.
I also use an improved form of bolt in connection with the above mechanism and
my trigger is mounted in solid ears formed upon the trigger plate.
In order that my invention may he 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 invention.
Figure 1, is a longitudinal section through the lock of my gun.
Figure 2, is a sectional plan of same.
Figure 3, is an elevation of one side showing one of the indicators.

"
In carrying my invention into effect I form my trigger T solid and provide the
ratchet wheel R having the ten teeth or notches which I find to be the best
number for the required pull, and having upon each side five arms which operate
in their movement the sear releasers. The ratchet B which is mounted on the
trigger T and operated by the spring 6' operates the ratchet wheel R and by means
of the arms the sear releasers are alternately operated upon each side. The
coiled trigger spring S is arranged in the rear end of the block D of trigger plate
so as to return the one end of trigger after it has been pulled. An indicating
disc E is provided in the lock plate A at each side having the two slots e' and
which expose the words "off" or on as may be by reason of that particular side
having been fired or not this being effected by means of the discs E being attached
to the tumbler V by the arbor n so that when on cock the one slot e¹ will expose
the word " on as seen at Figure 4 while the word "off" is hid, but upon being
fired the other slot e exposes the word "off" Figure 3 and the "on" is hidden
thus showing the condition of either or both the barrels and which has been fired.
The trigger is locked or bolted by the bolt H which is mounted so as to slide
with its end clear of the action of the trigger as shown by dotted line * but in
the case of the trigger being locked the word "safe" exposed on the top of the
lock at K this word being covered by the button L when it is pushed forward for
firing the gun. The trigger is mounted in solid ears M formed upon the trigger
plate m¹.
,
Having now particularly described and ascertained tl 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 having one trigger the ratchet wheel R trigger T
and spring S combined and operated substantially as and for the purpose herein set
forth and shown upon the accompanying drawings.
2nd. In double barrel guns having one trigger the dis s E operated substantially
such as and for the purpose herein set forth and shown.
3rd. In double barrels guns having one trigger the 1 H substantially as and
for the purpose herein set forth and shown upon the accc nanying drawing.
