An Improved Apparatus for Bending or Flanging Metal Plates.
THOMAS WILLIAM SIDGWICK 147 Grange Road East Middlesbrough Boiler-
smith do hereby declare the nature of this invention to be as follows:-
It consists I of a bed or block of any metal having a groove or slot, or anything
of a like nature, in which worked by a screw or any other means is another bed or
block having a projection on the upper edge above the block. This is connected
by any means to the bottom of the jaw or gap of a plate punching or shearing
machine.
II. A wedge shaped piece of steel, or any other metal is connected by any means
to the moveable slide of the head of the same machines, above the block I, and
vertically clear of the projection.
The side or end of a plate is introduced between the parts I and II resting on
the projection. By the action of the machine the wedge shaped part II presses
upon it forcing it down, on one side of the projection at the same time the
projection forces up the other, and so flanging or bevelling a plate.
The part I may be all in one piece without a screw etc.
The projection of part I & the wedge shaped piece of part II may be curved or
any shape.
The part I may have two or more projections.

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:-
It consists I-Of a bed, block or box A of any metal, having a groove, slot or
anything of a like nature B, through the ends of which is fitted the rods C, screwed,
so that by turning round, by any meaus moves inwards, or outwards, as required.
Above the box A, and resting on the sides, are two shaped pieces of metal D,
pivoted together by the bolt E through the sides, each having a fork or eye F
below the pivot, to go over the rods C. To the ends of the rods C, and at each
side of the forks or eyes F, is fitted a nut, pin, cotter, washer, or projection G by
any means. The whole of this is connected by any means to the bottom of the
jaw or gap of a plate punching, shearing, hydraulic, or other machine.
II. To the moveable head of the same machine is attached by any means, above
the first part, a wedge shaped, or any other shaped piece of metal H, clear of and
vertically between the shaped pieces of metal D.

page_text: Any one of the sides, or ends of one or more metal plates, is introduced, between
the parts of sections I & II resting on the projections D.
By the action of the machine the wedge shaped part H presses on the plate or
plates forcing it or them down between the parts D thereby bending or flanging it
or them.
One or both parts D may be immoveably attached to the bed, block or box A
thereby dispensing with the rod or rods C, pivot and bolt E, and the fork or
forks F.
One or both parts D may be made to slide on the upper edge of the bed, block,
or box A dispensing with the pivot and bolt E, and semicircular part of the sides
through which the bolt passes.
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 :-
I. For a combination of part or parts herein described for bending or flanging
metal plates introduced between the parts of sections I and II by the process
herein described.
