I, ALFRED CHRISTOPHER KOERNER engineer of 21 rue royale Paris France do
hereby declare the nature of my invention to be as follows:-
The objects of these improvements are: First, to facilitate aiming and firing a gun
with which recoil is permitted, by providing an attachment such that, in aiming, the
gun servant may use his firing hand to aid in supporting and moving the gun, whilst,
at the same time, he may fire the gun without removing his firing hand, from the
aforesaid attachment; which movement would otherwise cause loss of time and
disturbance of aim. Second, and in connection with this combined aiming and firing
attachment, a novel construction of Trigger for tripping the firing mechanism of a gun.
FIRST IMPROVEMENT. COMBINED AIMING AND FIRING ATTACHMENT.
For this purpose, a hollow Handle is rigidly connected to a projection the so-called
deflector of the shoulder piece in a convenient line and position for the right hand of
the gun servant when aiming the gun. This Handle is constructed in two main parts,
one, rigidly attached to the projection of the shoulder-piece and being of a convenient
size and shape for the grasp of the hand; the other, fitted to telescope or slide in and
out in the fixed part, and having an enlarged head or a cross projection at its outer end.
A Firing Laniard connects the movable part of the Handle directly with the Trigger.
By this arrangement, the gun servant in ainning seizes the Handle with one hand
and is thus enabled to utilise the strength of this hand in aiming, up to the moment
of firing when, by simply sliding his hand to the rear, the enlarged head of the
movable part is caught the movable part is pulled back and with it, the Trigger, which
fires the gun. The Trigger by its automatic return movement draws the movable part
of the Handle back to its place. Thus the firing hand of the gun servant may be
utilised to aim and to fire the gun at one and the same time.

page_text: SECOND IMPROVEMENT. NOVEL CONSTRUCTION OF TRIGGER.
This consists of a Trigger, of bent lever shape and action, pivoting on a pin through
its bend and hung in a small Lug piece, secured to the lower side of the breech of the
gun, convenient to the projecting end of the sear of the Firing mechanism. The upper
arm of this Trigger is held well forward by a small spiral spring lodged in the Lug piece
and around the pivot pin. The end of a Firing Laniard is attached to the lower
extremity of the Trigger.
When, in closing the breech of the gun, the breech block is lifted up to its place,
the end of the sear, which projects from the rear of the block, catches the upper and
forward end of the trigger. The firing Taniard being pulled, the front end of the
trigger is pulled down, pressing the scar down and thus tripping the firing bolt or
Hammer and firing the gun. Unless the breech block is completely closed, the Trigger
will not bear on the scar and thus, prematuro discharge by means of the Firing
Laniard is prevented.

Improvements in the Firing Mechanism of Rapid Firing and other
Guns.
I, ALFRED CHRISTOPHER KOERNER engineer of 21 rue royale Paris, France, do
hereby declare the nature of this invention and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement:-
The objects of these improvements are First to facilitate aiming and firing a gun with
which recoil is permitted by providing an attachment such, that in aiming, the gun
servant may use his firing hand to aid in supporting and moving the gun, whilst and
at the same time, he may fire the gun without removing his firing hand from the
aforesaid attachment, which movement would otherwise cause loss of time and
disturbance of aim. Second and in connection with this combined aiming and firing
attachment a novel construction of trigger for tripping the firing mechanism of a gun.
FIRST IMPROVEMENT, COMBINED AIMING AND FIRING ATTACHMENT FIG. 1 & 2.
For this purpose a hollow handle A is rigidly connected to a projection B (the so
called) "deflector" of the shoulder piece C in a convenient line and position for the
hand of the gun servant when aiming the gun.
This handle is constructed in two main parts, one A rigidly attached to the pro-
jection B of the shoulder-piece and being of a convenient size and shape for the grasp
of the hand, the other D fitted to telescope or slide in and out of the fixed part A and
having an enlarged head or a cross projection at its outer end.
A firing laniard E connects the movable part D of the handle directly with the
trigger F.
By this arrangement, the gun servant, in aiming, seizes the handle with one hand
and is thus enabled to utilise the strength of this hand in aiming up to the moment
of firing when, by simply sliding his hand to the rear, the enlarged head of the
movable part D is caught, the movable part is pulled back & with it the trigger
which fires the gun. The trigger, by its automatic return movement, draws the
movable part D of the handle back to its place. Thus the firing hand of the gun
servant may be utilised to aim & to fire the gun at one and the same time.

page_text: mechanism. The upper arm of this trigger F is held well forward by a small spiral
spring J lodged in the lug-piece H' and around the pivot pin G. The end of the
firing laniard E is attached to the lower extremity of the trigger F.
When in closing the breech of the gun, the breech-block is lifted up to its place,
the end of the sear I which projects from the rear of the block, catches the upper and
forward end of the trigger F, fig. 1 the firing laniard E being pulled, the front end of
the trigger F is pulled down, pressing the sear I down and thus tripping the firing
bolt or hammer and firing the gun. Unless the breech block is completely closed, the
trigger will not bear on the sear and thus premature discharge by means of the firing
laniard is prevented.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be perforined, I declare that what I
claim is
Firstly a device composed substantially of a handle made of two parts A D of
which A is stationary and the other D which actuates the laniard E is capable of a
sliding motion, with regard to the part A, whereby the gunner is enabled to use his
right hand simultaneously for aiming and firing the gun, substantially as described
and shewn in fig. 1 & 2 of the drawing.
Secondly the construction of trigger composed of a pivoted spring arm F connected
by its lower portion to the laniard E and resting at its upper portion upon the end of
the sear I substantially as described and shewn in fig. 3 & 4 of the drawing.
