Improvements in Single Trigger Double Barrel Guns.

page_text: Improvements in Single Trigger Double Barrel Guns.
I, HARRY GREENER, of 22, Saint Mary's Row, in the City of Birmingham, Gun
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in single trigger double barrel guns,
and its object is to provide means whereby the recoil action from firing shall be
utilized to prevent the liability to accidentally firing the next barrel; also the
adaptation and arrangement of such means whereby with the one trigger such
barrels may be consecutively fired.
According to this my invention I employ a movable piece which shall in its
normal state lie in a position to operate, or to permit of the operation of the sear
lever of the first barrel, but which after firing shall finally assume a similar posi-
tion for the next barrel sear lever.
This movable piece consists of a sliding block carried upon the trigger, in such
a manner that it may with the lifting of the trigger operate the sears.
The shape
and disposition of this block is also such that upon the recocking of the gun it is
automatically adjusted into position for action by the falling movement of the rear
sear tail.
The said sliding block is pressed forward into position by a spring,
but is so arranged that it will under recoil action, move considerably rearward
from the sear levers.
It is well known that in guns of this class, when a barrel has been fired, in the
recoil which follows, the trigger finger is liable (unwittingly) in the rapid return
forward movement of the gun, to fire the next barrel. Now my invention is
intended to obviate this, somewhat as follows:-
In the sudden rearward movement of the recoil which succeeds the firing, an
impetus is given to the said sliding block which considerably overcomes (for the
time being) the opposite force of the spring, consequently the said block is thrown
backward considerably, so that ere the spring has had sufficient time to bring it
again forward to the position for the next sear, all danger due to the return
(forward) movement of the gun against the trigger finger causing it to be fired,
has passed, or even should the trigger be inadvertently lifted no firing can take
place.

According to this my invention I employ a movable piece which shall in its

lever of the first barrel, but which after firing shall finally assume a similar posi-
tion for the next barrel sear lever.
This movable piece consists of a sliding block carried upon the trigger, in such
a manner that it may with the lifting of the trigger operate the sears.
The shape
and disposition of this block is also such that upon the recocking of the gun it is
automatically adjusted into position for action by the falling movement of the rear
sear tail. The said sliding block is pressed forward into position by a spring,
but is so arranged that it will under recoil action, move considerably rearward
from the sear levers.
It is well known that in guns of this class, when a barrel has been fired, in the
recoil which follows, the trigger finger is liable (unwittingly) in the rapid return
forward movement of the gun, to fire the next barrel. Now this my invention is
intended to obviate this, somewhat as follows:-
In the sudden rearward movement of the recoil which succeeds the firing, an
impetus is given to the said sliding block which considerably overcomes (for the
time being) the opposite force of the spring, consequently the said block is thrown
backward considerably, so that ere the spring has had sufficient time to bring it
again forward to the position for the next sear, all danger due to the return
(forward) movement of the gun against the trigger finger causing it to be fired,
has passed, or even should the trigger be inadvertently lifted no firing can take
place.
In order to more clearly explain this my invention, I have appended hereunto
an illustrative sheet of drawings upon which are figures and numbers of reference,
similar numbers referring to similar parts throughout the several views, and in
which:-
Fig. 1, is a general side view of my invention, with both barrels unfired.
Fig. 2, is a plan view of the invention on line A-B (Fig. 1).
Fig. 3, shows the position of the parts after the first barrel has been fired and
the recoil action is taking place.
Fig. 4, shows the position of the parts after the recoil action has taken place,
and which are now in position for firing the second barrel.
Fig. 5, is a detailed side and end view of the sliding block.
I have only illustrated such parts of the gun that may be necessary to explain
this my invention.
8, is the breech block, 9, the barrel, 10, the bolt lever, 11, the trigger guard
plate, 12, the trigger, 13, 13, the sear levers.
14, is a sliding block, carried upon the trigger and pushed forward by spring 15.
Upon reference to Figs. and 2, it will be seen that this block rests beneath
the right hand sear 13", ready for firing.
In the sudden rearward movement of the gun under the recoil which follows
the firing, an impetus is given to the said block which considerably overcomes
(for the time being) the opposite force of the spring, consequently the said block
is thrown back considerably as shown in Fig. 3, so that ere the spring 15, has had
sufficient time to bring the block forward to near the sears, all danger of firing
unintentionally from the recoil movement has passed. Upon the relief of pressure
upon the trigger, the block passes beneath the left hand sear 13, as shown in
Fig. 4, ready for firing the left barrel.

page_text: It will be noticed that the fore part of the sliding block is inclined at 16, con-
sequently upon the recocking of the gun, the end of the sear lever 13ª, in its descent
presses thereon and automatically pushes it backward into position for action.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. In single triggered guns having more than one barrel, the combination
with the trigger of a sliding block 14, which owing to the velocity of its movement
under recoil is kept clear of the succeeding sear for a given time and then brought
into position for next firing, substantially as set forth and shown.
2. In single triggered guns having more than one barrel, with a sliding
block 14, subject to movement under recoil action, the resetting of such movable
piece under the sear by the replacing action of the sear, substantially as described
and set forth.
