Improvements in Machinery or Apparatus to be Used in the Manu-
facture of Flanged Metallic Articles, such as the End-plates
of Steam Boilers, Frame Plates for Rolling Stock, and other
similar Articles.
I, SAMSON FOX, of the Leeds Forge, New Wortley, Leeds, in the County of York,
Engineer and Ironmaster, do hereby declare the nature of this invention to be as
follows:
In the manufacture of flanged metallic articles such as the end plates of steam
boilers, frame plates for rolling stock and other articles of a like nature, the flanges
by whatever process formed, are usually made at first somewhat broader than they are
designed to be when finished, and in most cases the flanging process produces flanges
of great irregularity in breadth which have to be afterwards finished off to the required
size an operation that, as heretofore usually performed, is costly.
Now my invention has reference to machinery designed to facilitate and reduce the
cost of such reduction and finishing of flanges. It comprises a suitable table or
platform provided with casters or rollers capable of adjustment in height above the
said table according to the breadth of flange required.
They are intended to receive and support the flanged article with the body or plain
part of it resting thereon and with the flange downward in such a way that the said
article when so supported can be easily moved in any required direction.
In connection with the said table there is mounted shearing mechanism having a
fixed blade arranged so that it will be at one side of the flange to be operated upon,
and a movable blade that will then be at the other side, this latter is operated inter-
mittently in any suitable manner, it may be either in a direct manner by bydraulic
pressure, or by hydraulic pressure applied through a toggle arrangement.
When the flange is in proper position the movable blade is caused to make a
stroke, to cut off a portion of the superfluous and irregular part of the flauge and then

page_text: retire, after which the article is turned or moved upon the beforementioned casters so
as to place another portion of flange between the shears, whereupon another stroke of
the movable blade is made to take off another portion of flange and so on till the
entire flange has been passed between the shears and it has been reduced to nearly the
required and of a uniform breadth. The flange can be afterwards trimmed in a suit-
able machine that will cut in the longitudinal direction of it and finish it smoothly
ready for use.
This operation will by the use of my invention be rendered less troublesome than
heretofore and consequently will take less time and be performed at less cost than
heretofore.

COMPLETE SPECIFICATION.
Improvements in Machinery or Apparatus to be Used in the Manu-
facture of Flanged Metallic Articles, such as the End Plates 1
of Steam Boilers, Frame Plates for Rolling Stock, and other
similar Articles.
I, SAMSON Fox, of the Leeds Forge, New Wortley, Leeds, in the County of York,
Engineer and Ironmaster, 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 :-
In the manufacture of flanged metallic articles such as the end plates of steam
boilers, frame plates for rolling stock and other articles of a like nature, the flanges
by whatever process formed, are usually made at first somewhat broader than they
are designed to be when finished, and in most cases the flanging process produces
flanges of great irregularity in breadth which have to be afterwards finished off to the
required size, an operation that as heretofore usually performed is costly.
Now my invention has reference to machinery designed to facilitate and diminish
the cost of such reduction and finishing of flanges. It comprises a suitable table or
platform provided with casters or rollers capable of adjustment in height above the
said table according to the breadth of flange required or the castor may be clamped
on the article to be operated upon.
They are intended to receive and support the flanged article with the body or plain
part of it resting thereon and with the flange downward in such a way that the said
article when so supported can be easily moved in any required direction.

page_text: In connection with the said table there is mounted shearing mechanism having a
fixed blade arranged so that it will be at one side of the flange to be operated upon,
and a movable blade that will then be at the other side, this latter is attached to a
sliding part and operated intermittently in any suitably manner, it may be either in
a direct manner by hydraulic pressure, or by hydraulic pressure applied through a
toggle arrangement.
When the flange is in proper position for being operated upon and bearing against
the beforementioned fixed blade, the movable blade is caused to advance and to cut off
a portion of the superfluous and irregular part of the flange and then retire, after
which the article is turned or moved upon the beforementioned casters so as to place
another portion of the flange between the shears ready for another cut, whereupon the
movable blade is again caused to advance and take off another portion of the
superfluous part of the flange, and so on until the entire flange, has been passed
between the shears and been reduced to nearly the required and of a uniform breadth.
or otherwise: The flange or flanges can be afterwards trimmed in a suitable machine
that will eut in the longitudinal direction and make a smooth finish ready for use.
This operation will by the use of my invention be performed with less trouble, in
less time, and at less cost than has heretofore been usual."
In the accompanying drawings similar letters refer to similar parts throughout the
several Figures. Fig. 1. Sheet 1. is an elevation partly in section, of machinery or
apparatus according to my invention. Fig. 2. is a plan, a. is a table or platform,-b, b;
are casters or rollers upon which a flanged article under treatment is mounted, and
are in sufficient number to support the article in proper position for being operated
upon, e, is a flanged article (in part),-d, the shearing mechanism in connection with
the said table or platform, (or it may be independent thereof.)-e, the fixed shear
blade, the movable blade attached to the slide g, to which is jointed the part 1, of
the toggle arrangement h, i, and link k, of the actuating mechanism of the movable
blade f
-
.
The link, is connected to the ram l, of a hydraulic motor,-m, is the hydraulic
cylinder, n, a valve for admitting water or other actuating fluid under pressure to
the cylinder m. p, a lever for actuating the valve n, when a flanged article has been
placed in position for being operated upon.
Figs. 3, and 4, Sheet 2, shew the casters 6, instead of being fixed to the table a,-
attached to the flanged article c, under treatment, and in an inverted position which
will thus roll upon the table when the said article is being intermittently moved for
shearing.
A modification in the arrangement of the shearing mechanism is shewn in
elevation in Fig. 5, Sheet 3. and in plan in Fig. 6.-in end elevation in Fig. 7,
sheet 4. Fig. 8, being 21 transverse section at B. B of Fig. 5. shewing the shear
slide g, the movement of which is effected in a direct manner, that is, without the
use of the toggle device as previously referred to and shewn in Figs. 1. and 2.-a, is
the table or platform, b. b, casters, c. the flanged article under treatment, as in the
said Figures 1. and 2.

The shearing action in this modification is the reverse of that previously described
and illustrated in Figs. 1. and 2, and operates from the inside of the flange to be shorn.
d' is the fixed jaw to which the stationary shear blade e. is fixed. f, is the movable
blade attached to the slide g.
The
On the rear of the slide g, is mounted a crossheady to which two rods ', ' are
connected, the other ends of these rods are connected to a corresponding
crosshead on the end of the ram of a hydraulic motor. m, is the hydraulic
cylinder attached to the body of the machine or shearing apparatus.
ram is provided with a head suitably packed to fit the bore of the
cylinder m, the reduced part of the ram passes through a stuffing box at the rear
of the cylinder m, m', and m², are both, alternately, ingress and egress ports for
water or other actuating fluid under pressure, this is regulated by a valve (not shewn
in the drawings) which may be operated either automatically or by hand, for
imparting the advancing and retiring movements to the shearing mechanism. The

page_text: fluid acts upon the whole area of the ram head 1, at 12, on its outward or shearing
stroke and thus by means of the rods ', ', causes the slide g, to advance and shear
the flange. On the return stroke of the shear slide the fluid acts on the annular
part 13, of the ram head. After the said return movement of the slide Ir the article
under treatment is moved so as to place another portion of the flange between the
shear blades for the next cut, and so on.
0, 0, 0, 0 are collars on the rods h', ', for
determining the length of stroke of the movable shear, and bear alternately against
the projections 7, 7, of the body of the machine.
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 :-
:-
The improved machinery or apparatus for reducing the flanges of flanged metallic
articles to a uniform breadth or otherwise as may be required, constructed, arranged
and operating substantially as hereinabove described with reference to the drawings
annexed.
