Our invention relates to an apparatus for flanging boiler or any other kind of
metal plates by means of which the edge of the plate turned over or flanged in a
more regular way than by hammering thereby producing better work and with
less liability to crack and effecting great saving of time, labour and expense.
For this purpose we construct a strong upright cast iron frame having at a
suitable height a cast iron table or bed plate within which is formed a long slot
hole to allow the sliding backwards and forwards of the receiving block which
supports the centre of the plate to be operated upon, and which is moved or
adjusted according to the size of the plate to be flanged.
The plate to be flanged is held in position in its centre while being operated
upon, by a screw working in a horizontal cross-bar and at each side of the cross-
bar are adjustable friction-rollers which are set to bear upon the plate and hold it
in a horizontal position to prevent it from bending or buckling.
The receiving block rests upon a bed plate sliding upon the top of the cast iron
table and upon this bed plate are screwed two pillars which support the cross bar
in which works the adjusting screw and also the before mentioned friction rollers.
The plate carrying the receiving block being brought into position is fixed in its
place by means of a screw and nut.
Near the end of the slot hole is fitted in position a block carrying a horizontal
revolving dise which is actuated by a shaft passing through the block and the table
and supported at the underside of the table by a bearing.
Under the table and on this shaft is attached with a sliding key, a pinion wheel
geared into another pinion which is fixed upon a horizontal shaft passing through
the upright frame of the machine and driven by wheel gear as hereinafter
explained.
This block carrying the horizontal disc is kept in set position by a bolt at each
side of the upright frame fixed in two lugs cast on the block and passing through
lugs on the side of the upright frame and the block is secured in position by nuts

page_text: screwing up to the lugs on the upright frame the distance being regulated according
to the thickness of the plate being flanged.
The upright frame is made with a projecting top piece in which is fitted guides
in which slides a moveable block supporting a roller which is pressed down on the
edge of the plate being operated upon to hold it flat in position and is adjusted as
required by an eccentric worked by a handle. At a convenient distance from the
revolving horizontal disc is fitted another iron disc revolving at right angles with
it and which presses down the edge of the iron plate to be flanged and forms the
flange by downward pressure gradually as the plate revolves. This last mentioned
disc for forming the flange is raised or lowered by a powerful screw worked by a
large hand wheel or by self acting gear. The disc is supported by a sliding block
through which works the powerful adjusting screw.
At the back of the upright frame works upon a stud, a pinion which may be
driven by steam, hand or other power. This pinion drives a large spur wheel
which actuates the shaft of the upright revolving disc and also drives another spur
wheel which is keyed upon the shaft of the pinions actuating the horizontal
revolving disc. The plate having been fixed in position on the receiving block and
fixed there by the screw the edge being placed in the required position to form the
depth of the flange the roller is brought to bear on the top of the plate and the
upright disc is brought down to press down the metal at the same time the
horizontal revolving disc continues to turn which gradually brings the plate into
forcible contact with the upright revolving disc thereby turning down the edge
into the required flange.

ticularly described and ascertained in and by the following statement:―
"
Our Invention relates to an apparatus for flanging boiler or any other kind of
metal plates by means of which the edge of the plate is turned over or flanged in
a more regular way than by hammering thereby producing better work and with
less liability to crack and effecting great saving of time labour and expense.
For this purpose we construct a strong upright cast iron frame, having at a
suitable height a cast iron table or bed plate within which is formed a long slot
hole to allow the sliding backwards and forwards of the receiving block which
supports the centre of the plate to be operated upon and which is moved or
adjusted according to the size of the plate to be flanged.
The plate to be flanged is held in position in its centre while being operated
upon by a screw working in a horizontal cross-bar and at each side of the cross-
bar are adjustable friction rollers which are set to bear upon the plate and hold it
in a horizontal position to prevent it from bending or buckling.
The receiving block rests upon a carriage sliding upon the top of the cast iron
table and upon this carriage are screwed two pillars which support the cross-bar
in which works the adjusting screw and also the before mentioned friction rollers.
The carriage carrying the receiving block being brought into position is fixed in
its place by means of a screw and hand wheel.
Near the end of the slot hole is fitted in position a block carrying a horizontal
revolving disc which is actuated by a shaft passing through the block and the table
and supported at the underside of the table by a bearing.
Under the table and on this shaft is attached with a sliding key a pinion wheel
geared into another pinion which is fixed upon a horizontal shaft passing through
the upright frame of the Machine and driven by wheel gear as hereinafter
explained.
This block carrying the horizontal disc is kept in set position by a bolt at each.
side of the upright frame fixed in two lugs cast on the block and passing through
lugs on the side of the upright frame and the block-is secured in position by nuts
screwing up to the lugs on the upright frame the distance being regulated according
to the thickness of the plate being flanged.
The upright frame is made with a projecting top piece in which are fitted guides
in which slides a moveable block supporting three rollers which are pressed down

page_text: on the edge of the plate being operated upon to hold it flat in position which
block is adjusted as required by an eccentric worked by a handle. At a convenient
distance from the revolving horizontal disc is fitted another iron disc revolving at
right angles with it and which presses down the edge of the iron plate to be flanged
and forms the flange by downward pressure gradually as the plate revolves. This
last mentioned disc for forming the flange is raised or lowered by a powerful screw
worked by a large hand wheel or by self acting gear. The disc is supported by a
sliding block through which works the powerful adjusting screw.
At the back of the upright frame working upon a stud is a small pinion which
may be driven by steam band or other power.
This pinion drives a large spur wheel which actuates the shaft of the upright
revolving disc and also drives another spur wheel which is keyed upon the shaft
of the bevel wheel actuating the horizontal revolving disc.
. The plate having been fixed in position on the receiving block and fixed there
by the screw the edge being placed in the required position to form the depth of
the flange the rollers are brought to bear on the top of the plate and the upright
disc is brought down to press down the metal at the same time the horizontal
revolving disc continues to turn which gradually brings the plate into forcible
contact with the upright revolving disc thereby turning down the edge into the
required flange.
In order to enable our Invention to be fully understood we will proceed to
describe the same by reference to the accompanying drawing in both the figures of
which similar letters refer to similar parts.
Figure 1 represents a side elevation of the machine and Figure 2 a plan of the
same.
A is the upright frame and B the table or bed-plate projecting from it; a slot
is formed in the bed-plate B to guide the carriage C which is adjusted by means
of the screw D and the hand wheel E and fixed by the nut M. At each end of
the carriage C are fixed pillars F supporting a horizontal cross-bar G on, which
slide blocks H carrying the rollers J which keep the plate operated upon straight
and prevent it buckling; a screw K passes through the middle of the cross-bar G
to the centre and holds the plate on the receiving block L fixed on the carriage C.
The block N carrying the horizontal flanging disc O is placed on the bedplate B
and adjusted by the screws P and fixed by the bolt Q. The horizontal disc O
is actuated by the bevil wheels R which bevil wheels are connected to the driving
pulley S by the spur wheel T and pinion U.
The frame A is made with a vertical slot in which slides the block V and the
vertical disc W is fixed on the end of a shaft passing through the block. V and is
actuated by means of the spur wheel X gearing in the pinion U. The pulley S
attached to the pinion U runs on a stud fixed in the block V, and in the lower
part of the block V bearings are formed to carry the shaft F¹ on which are fixed
the spur wheel T and one of the bevel wheels R.
The relative distance of the flanging discs O and W is regulated by the combined
use of the screw Y and hand wheel Z which raise and lower the block V and the
screws P which move the block N along the bed plate B.
The roller A¹ and the two rollers B₁ are for the purpose of pressing the plate
operated upon down on the horizontal disc and to prevent it buckling. They
are fitted to a block C₁ sliding in a vertical dovetailed slide formed in the top
projection of the frame A and are adjusted vertically by means of the eccentric D
and hand lever E¹.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed. We declare that
what we claim is
1. The method of driving and adjusting the flanging discs substantially as
herein described.

page_text: 2. The combination of such flanging discs with the friction and pressing rollers
and the means of adjusting the same substantially as described and represented in
the accompanying drawing.
3. The means for adjusting the carriage carrying the receiving block for centering
the plate as herein before described.
