COMPLETE SPECIFICATION.
Improved Machines and Apparatus for Bending, Flanging, or Setting
Steel, Iron, or other Metal Plates.
HUGH SMITH Senr., HUGH SMITH Jun., and OSBOURNE SMITH, Engineers,
Possil Engine Works, Glasgow, in the County of Lanark, 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:—
Our invention consists, in the first place, in a machine for bending, flanging, or
setting steel, iron, or other metal plates, as shown in the drawings hereunto
appended, in which Figs. 1 and 2. Sheet 1. represent respectively a plan and
elevation.
In Figs. 1 and 2, Sheet 1, A. and B. represent two cheeks or frames, which
are fixed or bound together by means of a beam or rail C. and two stays D.
E. represents a beam or rail fitted at the two ends into the cheeks or frames A
and B in such a manner that the beam or rail E can be removed or lifted up to
facilitate the getting out and in of the plates to be bent, flanged, or set by the
machine.
One method of lifting out the beam E. is shown in Fig. 2, Sheet 1. in which
F. represents a cylinder in which a piston and piston rod slide, the end of the piston
rod being attached to the end of the beam E., so that when pressure water is
admitted to the bottom side of piston the beam E. is lifted up leaving a clear space
between the cheeks or frames A. and B.
G. represents a beam or rail which is free to move horizontally being guided at
the ends in the cheeks or frames A. and B.
K. represents a cylinder in which a ram with piston is arranged to work up and
down by means of pressure water, and, the end of the said ram being attached to a
wedge H., causes the said wedge H. also to work up and down. The wedge H.
works in guides on the one side on the fixed beam C. and on the other side on the
moveable beam (., and thus, as the wedge H is caused to move up and down it will
cause the beam or rail G. to move back and forward.
M. represents a die block fitted into the beam or rail G., and R. represents a
nose bar fitted to the beam or rail E. The said die block M. and nose bar R. may
be made of any suitable form to suit the flange, bend, or set required to be done in
the machine. P. represents a plate put into the machine to be bent, flanged, or
set, and this is performed by causing the beam or rail G. to be moved forward as
hereinbefore described, which causes the plate to be bent, flanged or set according
to the shape of the die block M. and nose bar R. The removing of the beam E.
when the bending flanging or setting of the plate has been done enables us to remove
complete square, rectangular or circular frames, or any shape of frame which cannot
otherwise be easily removed from the machine.
We may place this machine either horizontally or vertically, and we may work
this machine as hereinbefore described, or we may arrange that the beam G. be
moved back and forward by means of pressure water acting in a cylinder or
cylinders having ram or rams acting direct on to the beam G. instead of by means
of a wedge H. as hereinbefore described. Or we may arrange that the beam G. be
moved backwards and forwards by means of screws working in nuts placed in the
cheeks or frames A. and B., and we may arrange that the beam or rail E. may be
removed by gear or tackle instead of by pressure water acting on a piston as herein-
before described.
Figs. 1. and 2., Sheet 2. represent respectively an end and front elevation of
another modification of the machine, as shown on Figs. 1 and 2. Sheet 1., for
bending, flanging, or setting iron, steel or other metal plates, similarly to that

page_text: described in connection with Figs. 1. and 2., Sheet 1., but being placed horizontally
and having cylinders C. and rams B. actuated by means of pressure water and
acting directly on to, and causing to move up and down, the beam A. K. represents
a fixed beam or rail, and H. and G. represent respectively two end checks or frames,
the said check or frame H. being held in position by means of two bolts or stays D.,
and the aforesaid check or frame C. being held in position by two bolts or stays E.
and F. respectively. The bolt E. and the cheek G. are so arranged that they can
be hinged over, leaving the end of the beam K. clear; or we may arrange that
both the bolts E and F. and frame G hinge over to leave end of beam K. more
entirely clear. M. represents a die block attached to beam A. and N. represents a
nose bar or die attached to beam K. P. represents the plate to be bent, flanged,
or set; and L represents a bolt or stay for supporting the beam K. when frame G.
is hinged over or removed. When the plate P. is placed in position as shown the
pressure water is admitted to the cylinders causing the plate to be bent, flanged,
or set according to the shape of the die block M. and nose bar N.; and when the
said plate P. has been bent, flanged, or set, to any required shape or form either
by one or more operations the frame G. is removed or hinged over so that the
plate P. may be easily taken from the machine, and thus enabling us to remove
complete frames, as described in connection with Figs. 1. and 2., Sheet 1.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1st. The application of a wedge or wedges, actuated by hydraulic or other
power for moving a beam to and from another beam, the said beams having a die
block and nose bar or die attached to each respectively, all as hereinbefore
described.
2nd. The application of hydraulic or other power for removing the beam
round about which the plate is bent into a frame, to facilitate the removing of the
said frame all as hereinbefore described.
3rd. In a machine placed horizontally, the arrangement for carrying the beam
about which the plate is bent into a frame, and the slueing or hinging over of the
end bracket which carries the said beam, to facilitate the removing of the said
frame, all as hereinbefore described.
4th. The arrangement and combination of parts and appliances, and the method
of working same for the purposes described, and all as hereinbefore described in
connection with the drawings hereunto appended.
