PROVISIONAL SPECIFICATION.
Improvements in Flanging Machines.
I, URIAH BINNS, of the firm of Binns Brothers, of Victoria Iron Works, South
Parade, Halifax, in the County of York, Engineers' Tool Makers, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements on a machine known as "Hanson's Patent
Flanging Machine," principally used for flanging boiler flues, in which the tube to
be flanged is rotated in an inclined position on pulleys and a table, the flanging
being performed by forcing a roller gradually down upon the edge of the tube,
thus bending it to the desired shape.
The object of this invention is to provide the said machine with means which
will facilitate the formation of larger flanges and respective curves on boiler
flues than heretofore has been the case and prevent indents on same.
To this end my improvements consist in the application to the said machine of a
flanging roller operating in conjunction with the lower and upper flanging rollers
and adapted to swivel on or in the radially adjustable quadrant or arm carrying the
upper, flanging roller, so that on the same being forced gradually towards the lower
flanging roller, it will always accommodate itself to the metal from the beginning of
the flanging operation to the end and thus offer a wider rolling surface than hereto-
fore has been the case.

Improvements in Flanging Machines.
1, URIAH BINNS, of the firm of Binns Bros., of Victoria Iron Works, South
Parade, Halifax, in the County of York, Engineers, 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 :—
This invention relates to improvements on a machine known as "Hanson's Patent
Flanging Machine" principally used for flanging boiler flues, in which the tube to
be flanged is rotated in an inclined position on pulleys and a table, the flanging
being performed by forcing a roller gradually down upon the edge of the tube,
thus bending it to the desired shape.
The object of this invention is to provide the said machine with means which
will facilitate the formation of larger flanges and respective curves or boiler flues
than heretofore has been the case and prevent indents on the same.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a vertical section on line A-B of Fig. 3, showing the position of the
movable flanging rollers when the flange is finished.
Fig. 2 is a similar view showing the position of the movable flanging rollers at
the commencement of the operation.
Fig. 3 is a front view of the machine without the table.
Fig. 4 is an enlarged front view and Fig. 5 a plan of the oscillating flanging roller.

page_text: a is the bed plate, the table on which the tube c to be flanged is fixed, d the
support on which is rendered adjustable a slide e carrying the flanging roller /,
supporting pulleys g, worm h, shaft i, having attached a quadrant k and arm
carrying the flanging rollers m and n.
In carrying out my invention and referring to the figures generally, my improve-
ments consist in the application to the said machine of a flanging roller m operating
in conjunction with the lower and upper flanging rollers and n respectively, and
adapted to swivel on or in the radially adjustable quadrant arm 1 carrying the upper
flanging roller n. The flanging roller m I arrange to revolve on a stud o within a
'frame P which latter is mounted, in a cavity y formed in the arm l, between two
centre pins positioned in the checks thereof. On the flanging roller m being
forced gradually towards the lower flanging roller n, by means of the worm h,
quadrant and arm l, it always' accommodates itself to the metal or tube c from
the beginning of the flanging operation to the end and thus offers a wider rolling
surface than heretofore has been the case.
7°
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim, is-
In flanging machines of the class hereinbefore specified.
1st. The general construction and combination of parts constituting my improve-
ments operating substantially as and for the purpose set forth.
2nd. The use of a flanging roller m in combination with the radially movable
arm 1, which roller m is arranged to simultaneously revolve and swivel on being
forced against the tube end to be flanged and thus always accommodate itself
thereto, substantially as and for the purpose set forth.
