PROVISIONAL SPECIFICATION.
Improvements in Machinery for Flanging, Shaping, or Punching
Metal Plates.
I, ALEXANDER CARNEGIE KIRK, LL.D., of the firm of Robert Napier and Sons,
of Lancefield House, Glasgow, in the County of Lanark, North Britain, Engineer,
do hereby declare the nature of this invention to be as follows, that is to say :-
My said invention has for its object to construct or arrange machinery for
flanging, shaping, or punching metal plates in an improved manner so as to be
conveniently available for various operations required in making boilers, ships, and
other metal structures, and more especially operations in which the direct action of
an hydraulic ram is not suitable.
My present improvements are advantageously applicable as additions to flanging
machines of the kind described in my Patent Specification No. 4137 of 1882; and
they render such machines more useful for a comparatively small extra cost; they
may, however, also be arranged as separate machines.
In machinery made with my present improvements, whether combined or not with
the parts of the machine described in the said earlier Patent Specification, there is
a table or frame with an hydraulic cylinder underneath having a piston rod
extending up above the table and arranged to puli down and raise a lever to the
end of which a die used in flanging, shaping, or punching metal is attached, the
other dic resting on the frame or table. The lever, at the end opposite to that at
which the die is attached rests on the table or frame or on a support which serves
as a fulcrum to it, whilst the piston rod acts on it at some point between the ends
which may be best in each case for the particular work to be done.
Instead of there being a fulcrum at or near one end of the lever, there may, in
some cases, be a die attached at each end; or a triple-armed or multiple-armed
lever may be used with several dies arranged around the piston rod, the attachment
of the lever to the piston rod being, in such cases by a universal or equivalent
joint.

COMPLETE SPECIFICATION.
Improvements in Machinery for Flanging, Shaping, or Punching
Metal Plates.
I, ALEXANDER CARNEGIE KIRK, LL.D., of the firm of Robert Napier and Sons,
of Lancefield House, Glasgow, in the County of Lanark, North Britain, 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, that is to say :-
The said invention has for its object to construct or arrange machinery for
flanging, shaping, or punching metal plates in an improved manner so as to be
conveniently available for various operations required in making boilers, ships, and
other metal structures, and more especially operations in which the direct action of
an hydraulic ram is not suitable.
The present improvements are advantageously applicable as additions to flanging
machines of the kind described in the Patent Specification No. 4137 of 1882; and
they render such machines more useful for a comparatively small extra cost; they
may, however, also be arranged as separate machines.

page_text: In machinery made with the present improvements, whether combined or not with
the parts of the machine described in the said earlier Patent Specification, there is
a table or frame with an hydraulic cylinder underneath having a piston rod
extending up above the table and arranged to pull down and raise a lever to the
end of which a die used in flanging, shaping, or punching metal is attached, the
other die resting on the frame or table. The lever, at the end opposite to that at
which the die is attached rests on the table or frame or on a support which serves
as a fulcrum to it, whilst the piston rod acts on it at some point between the ends
which may be best in each case for the particular work to be done.
Instead of there being a fulcrum at or near one end of the lever, there may, in
some cases, be a die attached at each end, or a triple-armed or multiple-armed lever
may be used with several dies arranged around the piston rod, the attachment
of the lever to the piston rod, being in such cases by a universal or equivalent
joint.
And in order that the said invention and the manner of performing the same may
be properly understood there is hereunto appended a sheet of explanatory drawings,
to be hereinafter referred to, and showing examples of the improved devices.
Figure, 1, of the drawings is a plan and Figure, 2, a vertical section of one
modification, Figures, 3, and, 4, being similar views showing another modification.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
In Figures, I, and, 2, a modification of the improved devices is shown as com-
bined with parts of the machine described in the said earlier Patent Specification,
and is adapted for flanging metal. There is a table or frame, A, with an hydraulic
cylinder, B, underneath, having a piston rod, C, extending up above the table, and
arranged to pull down and raise a lever, D, the hydraulic cylinder and parts
connected with it being worked in the manner described in the said earlier Patent
Specification. To the end of the lever, D, a die or flanging block, F, is attached
the other or counterpart die or resisting block, G, being fixed to the frame or
table, A. The dic, F', is attached to the lever, D, by two links, H, (one on each
side of the lever), and the upper ends of which are connected by a pin, J, which
slides in a slot or recess, K, in a small piece, L, fixed on the lever. The lever, D,
at the end opposite to that at which the die, f, is attached, is connected by links, M,
to a block, N, fixed on the frame or table, A. The piston rod, C, has fixed across
its upper part a bar or cutter, P, which, when the piston rod is moved downwards
acting in a notch, Q, formed in the top of the lever, D, moves the lever downward
depressing the die, F, and causing it to act on the plate, R, to be flanged. The
die, F, is preferably of the kind and operates in the manner described in the Patent
Specification No. 16011 of 1890, and a block, S, fixed on the upper part of the
table or frame, A, is provided with a curved part facing the counter-part die, G,
and shaped to correspond with the path of the edge of the plate, R, whilst being
bended, and so as to turn the die inward to press the plate fully against the vertical
or nearly vertical face of the counter-part die. A cutter, T, is fixed across the
piston rod, C, under the lever, D, to raise the lever when the piston rod is moved
upwards; and when the piston rod is moved upwards, the die, F, is raised with it
by the links, H. A different die used in shaping or punching metal might be used
instead of the flanging die, (F), the same being attached to the lever, (D), in any
suitable manner.
In the modification shown in Figures, 3, and, 4, the lever or crosshead, D, has
fixed to each end a die or punch, F. The dies, F, are fixed in sockets, V, which
are fixed to the crosshead, D, and which are made so that punches of various sizes
can be fixed in them. Suitable blocks, G, for the plates, R, to rest on when being
punched, are provided, recesses, X, being formed in the top of the table or frame, A,
to engage with counterpart projections on the blocks which may be of various sizes
to suit the size of hole to be punched. The crosshead, D, is fixed to the upper
end of the piston rod, C, by.a nut, Z, screwed on the upper part of the piston rod.
It desired a die or other tool (F). used in flanging or shaping metal may be fixed to.

page_text: each end of the crosshead, D, instead of the punch and suitable counterpart dies or
resisting blocks may be provided.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. Combining the parts of machinery for flanging, shaping, or punching metal
plates, substantially as hereinbefore described with reference to Figures, 1, and, 2,
of the accompanying drawing.
2. Combining the parts of machinery for flanging, shaping, or punching metal
plates, substantially as hereinbefore described with reference to Figures, 3, and, 4,
of the accompanying drawing.
