I JACQUES PHILLIPPE PIERI of St Margarets Mansions, Victoria Street, West-
minster, Middlesex Gentleman, do hereby declare the nature of my said invention
for "IMPROVED MEANS OF SUPPORTING CANNON AND APPARATUS FOR RECEIVING
THE RECOIL to be as follows :—
"
The object of this invention is to so mount a cannon that during the recoil the
cannon shall rise off the trunnion supporting portion of its frame or carriage and
cant a lever whose fulcrum is below and to the rear of the trunnion centre, the
lower end of the lever acting against a spring bolt which tends to check and
subdue the recoil, the cannon then returning by its own weight to its first position
on to the cheeks of the supporting block or frame, this being preferably arranged
on a turntable for horizontal circular motion.
If the muzzle end of the cannon has a preponderance of weight it may bear
upon a lever fitted to the frame in such a manner that the lower end of the lever
can be acted upon by a threaded rod to adjust the cannon for elevation or depression.
If the breech end of the cannon has a preponderance of weight said lever would
be arranged in some other suitable position.
For the purpose of my invention I mount a cannon with its trunnions within
collars of a forked lever or it may be a pair of levers which I pivot to the
supporting frame said pivot being below and out of the vertical central line of
the trunnions.
The lever terminates in a lump or nose piece and presses against a spring bolt
fitted within the frame close to the base which may be arranged to turn in a
circular horizontal direction and carry the cannon round to any desired position.
Pivotted to the supporting frame is another lever on one end of which the fore end
of the cannon bears if it has a preponderance of weight in front of the trunnions
and by which it can be elevated or depressed by the turning of a screw shaft in
connection with the tail end of this lever the screw shaft having a small hand
wheel to facilitate the operation.
When the cannon is down in the position for firing the collars of the forked
lever in which the trunnions are fitted rest upon the cheeks of the supporting
block or frame either alone or in conjunction with the pivot of the forked lever.

I JACQUES PHILLIPPE PIERI of St Margarets Mansions, Victoria Street, West-
minster Middlesex, Gentleman, 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 this invention is to so mount a cannon that during the recoil the
cannon shall rise off the trunnion supporting portion of its frame or carriage and
cant a lever whose fulcrum is below and to the rear of the trunnion centre, the
lower end of the lever acting against a spring bolt which tends to check and
subdue the recoil the cannon then returning by its own weight to its first position
on to the cheeks of the supporting block or frame this being preferably arranged
on a turntable for horizontal circular motion. If the muzzle end of the cannon has
a preponderance of weight it may hear upon a lever fitted to the frame in such a
manner that the lower end of the lever can be acted upon by a threaded rod to
adjust the cannon for elevation or depression. If the breech end of the cannon
has a preponderance of weight said lever would be arranged in some other suitable
position.
For the purpose of my invention I mount a cannon A with its trunnions B, B,
within collars C of a forked lever D or it may be a pair of levers which I pivot
to the supporting frame E, said pivot F being below and out of the vertical central
line of the trunnions B, B.
The lever D terminates in a lump or nose piece G and presses against a spring
bolt H fitted within the frame E close to its base which may be arranged to turn
in a circular horizontal direction and carry the cannon round to any desired
position. Pivotted to the supporting frame E is another lever I on one end of
which the fore end of the cannon A bears, if it has a preponderance of weight in
front of the trunnions and by which it can be elevated or depressed by the turning
of a screw shaft J in connection with the tail end of the lever I, the screw shaft J
having a small hand wheel K to facilitate the operation.
When the cannon is in the position for firing, the collars C,'C, of the forked
lever D in which the trunnions B B are fitted rest upon the cheeks L of the
supporting block or frame E either alone or in conjunction with the pivot F of the
forked lever.
Figure 1 of the annexed drawings represents the cannon resting upon the cheeks
of the supporting block or frame E and in its normal position. Figure 2 shows
the position of the cannon and mechanism at the moment of the recoil, the spring MS
being compressed by the bolt H which is actuated by the nose piece Ġ of the
forked lever D. The spring M may be compressed by a plunger as shown at
Figures 1 and 2 or it may be compressed by a vertical pull action (the nose piece G
working in a slot N of the plunger rod P) as shown at Figure 3.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. Supporting a cannon loosely on a frame said cannon being connected to a
lever arranged to act upon a spring which returns it on to the frame after each
recoil.
2. The apparatus shown on the annexed drawings for supporting a cannon for
determining its elevation or depression and also its direction for firing and for
returning the cannon to its normal position all as set forth.
