Complete Specification Accepted, 7th Dec., 1838
1, THORSTEN NORDENFELT of 53 Parliament Street in the City of Westminster,
Civil Engineer, do hereby declare the nature of this invention to be as follows:-
:―
The object of my invention is to enable the gunner who lays the gun to retain his
position behind the gun when the gun is fired even if the gun is allowed to recoil a
certain distance.
I mount my gun on a recoil carriage in which the movement of the gun is
regulated by hydraulic buffers or springs or the two combined. The gunner lays
the gun transversely and vertically by means of a shoulder-piece and fires the gun by
pulling the trigger with his finger.
My invention relates to arrangements for allowing the gunner to pull the trigger
which communicates with the trigger lever in the mechanism which releases the
striker and to do this without releasing his grip of the trigger guard and without
getting his hand hurt when the gun recoils. In the specification of my Patent
No. 5451 in the year 1887 I claimed that this object could be gained by allowing
the trigger guard to slide on the gun and to take up the shock from the recoil by
means of a spring. I now propose to gain the same object by fixing the trigger
guard and its trigger to the cradle of the recoil carriage or to some part of the carriage
which does not partake in the recoil of the gun and I arrange my trigger in the same
way as described in the above mentioned specification.
I can arrange my trigger guard in several ways. For example it can be made
with a bracket fixed to the cradle or carriage, or I can allow it to slide in grooves
on the breech of the gun and connect it by a link to the carriage so that it slides
as compared to the breech when the gun recoils.

page_text: 1, THORSTEN NORDENFELT, of 53 Parliament Street in the City of Westminster,
Civil Engineer, 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 to enable the gunner who lays the gun to retain his
position behind the gun, when the gun is fired, even if the gun is allowed to recoil a
certain distance.
I mount my gun on a recoil carriage in which the movement of the gun is regulated
by hydraulic buffers or springs or the two combined. The gunner lays the gun
transversely and vertically by means of a shoulder piece and fires the gun by pulling
the trigger with his finger.
My invention relates to arrangements for allowing the gunner to pull the trigger
which communicates with the trigger lever in the mechanism which releases the striker
and to do this without releasing his grip of the trigger guard and without getting his
hand hurt when the gun recoils. In the Specification of my Patent No. 5451 in the
year 1887 I claimed that this object could be gained by allowing the trigger guard to
slide on the gun and to take up the shock from the recoil by means of a spring. I now
propose to gain the same object by fixing the trigger guard and its trigger to the
cradle of the recoil carriage or to some part of the carriage which does not partake in
the recoil of the gun and I arrange my trigger in the same way as described in the
above mentioned specification.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation showing the breech end of the gun and a portion of the
cradle or carriage on which the gun is carried.
Figure 2 is a plan of the same.
Figure 3 is a longitudinal section of the breech of the gun with the portion of the
cradle or carriage in elevation.
Figures 4 are detached views of the portion of the cradle or frame which as will
be seen is made in the form of a grip handle with trigger guard and it carries an axis.
with a trigger upon it.
Figures 5 show a mounting which is fitted upon the breech end of the gun ;
carries an axis which is turned by the operation of the trigger.
it
A is the breech block mounted on the axis B on which is also the lever handle C-
D is the wedge at the back of the breech block, it is withdrawn when the axis is
turned and then both wedge and breech block together turn about the axis and leave
the breech free. E is the striker or firing pin and F is its spring. G is the sear

page_text: lever by which the firing pin is retained when cocked. H is a spring acting on this
lever is a horizontal axis carried in the mounting shown by the Figures 5. M is
an axis carried by the part of the cradle or carriage shown by Figure 4; it has the
trigger finger M¹ descending from it at one end and at the other end an arm M².
This arm comes in front of a corresponding arm 1' on the axis I so that with the parts
in the firing position when the trigger axis is turned the axis I turns with it.
A small spring operating on the pin holds the arm I against the arm M².
On the axis I is a second arm I which when the breech is closed comes above the
rear end of the sear lever G and when the trigger is pulled forces downwards this
end of the lever and sets the firing pin free. The part shown by Figures 4 instead
of being a portion of the cradle or carriage might be connected with it by a link; the
action in either case is the saune; when the gun is fired it recoils whilst the said part
carrying the trigger remains with the cradle or carriage of which it forms a part or
to which it is attached.
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 :--
1. Carrying the trigger of the firing mechanism of a quick firing gun by a handle
or part connected to the cradle or carriage which does not partake in the recoil of
the gun.
2. Carrying the trigger on a handle or part connected to the cradle or carriage
which does not partake in the recoil of the gun, and forming the trigger axis in two
lengths, one, with the trigger upon it, carried by the said handle or part and the other,
which acts on the firing mechanism carried by the gun.
3. The construction of the firing mechanism of breech loading guns substantially
as herein before described and illustrated in the drawing annexed.
