Improvements in the Means or Method of Flanging the Ends of
Pipes and in Apparatus therefor.
I, JOHN WOTHERSPOON, of Clyde Tube Works, Coatbridge, in the County of
Lanark, North Britain, Tube Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to Improvements in the means or method of flanging the
ends of pipes and in apparatus therefor and has for its object to facilitate the said
flanging operation.
According to my improvements 1 mount at the end of a lathe bed either in con-
nection therewith or as a part of the lathe a strong head with a cover hinged on the
one side and having the necessary grip or catch for quickly fastening the said cover
at the other side, this head and cover being formed with a cylindrical opening into
which the pipe to be flanged is placed, the said pipe being allowed to project a
sufficient length by means of a suitably mounted guide so as to be formed into the
flange on the side of the head nearest the lathe head, the said lathe head being of a
suitable kind carrying a revolving spindle which is capable of moving longitudinally
by means of a suitably mounted lever or screw arrangement, the said spindle having
mounted eccentrically at the end nearest the pipe to be flanged, a roller, or flanging
plug, preferably having a part of a parallell cylindrical shape and then of a tapered
plug, so that it may be pressed against the inside end of the pipe and thus cause the
said pipe to take a kind of bell mouthed shape, after which I cause another roller of a
checked or flanged shape, and which revolves in the horizontal plane to come into
action, the said roller being suitably mounted on a movable revolving frame capable
of being moved longitudinally by means of a suitable lever or its equivalent this
roller being for the purpose of finishing the flange as on its being pressed against
the bell shape mouth of the pipe formed by the aforementioned operation it causes
the edge of the pipe to be pressed against a shoulder on the head and thus forms the
flange, the breadth or diameter of which may be regulated by the said flange or
check on this roller.

Improvements in the Means or Method of Flanging the Ends of
Pipes and in Apparatus therefor.
1, JOHN WOTHERSPOON of the Clyde Tube Works, Coatbridge in the County of
Lanark, North Britain Tube Manufacturer 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 which relates to improvements in the means or method of flanging
the ends of pipes and in the apparatus therefor, has for its object to facilitate the
said flanging operation and to effect the same in a more efficient manner than
hitherto.
In order that my Invention may be readily understood and easily carried into
effect, I will now proceed to describe the same, reference being made to the accom-
panying sheet of drawings, Figure 1 is an elevation, Figure 2 an end elevation, and

page_text: Figure 3 a plan of my said Improvements, whilst Figure 1 and 4 are sectional
detail parts shewn for the better illustration of the parts.
In accordance with my said improvements I mount a suitable frame or standard X,
or I may use the end of an ordinary lathe bed or other suitable machine and upon
the frame or lathe bed I mount a strong head A, having its top part A¹ hinged at a,
acting as a cover and held in its proper close position by means of a suitably
mounted catch or grip a'. The head and cover are formed with a cylindrical opening
for the purpose of holding the pipe B. to be flanged, the said pipe being allowed to
project a sufficient length through the head, so as to form the flange as at B¹, the
exact length being regulated by means of a suitable mounted guide b, either cast: on
the cover or fastened to it by bolts or their equivalents, the said guide acting only
when the cover is open, and the pipe being placed in position, after which it recedes
as the cover is shut down. To keep the said head cool and thereby prevent it
expanding by the heat which arises from the hot pipes or tubes to be flanged and the
great rapidity with which this is accomplished, I form the head as a hollow casing a²,
into which I cause a continuous circulation of cold water to pass through by means
of inlet a³, and outlet a, pipes, and I also form the cover hollow on top as, and cause
a supply of water to run into it by any suitable means, the waste water being allowed
to run off, or led away by any suitable means.
The flanging of the pipe is performed in two stages, by means of two discs or
rollers C, and D, the roller, or disc C, being mounted eccentrically on the end of a
revolving spindle E, which is capable of longitudinal movement, by means of the
clutch F, and the necessary lever arrangement and handle F¹, or in lieu thereof
the said clutch F, may be manipulated by a suitably mounted screw arrangement. The
said spindle E, is carried in a journal e, formed on the frame, and inside a revolving
clutch G, which works or revolves in a journal or head H, formed on the frame, the said
revolving clutch G, carrying the roller or disc D, also takes a longitudinal movement,
the same being obtained by the clutch ring J, with lever arrangement & handle J',
or by means of a suitably mounted screw arrangement or its equivalent.
As a modification for larger sizes, I may mount or arrange the revolving spindle E,
the revolving clutch G, and journal in frame H, with the discs or rollers C, and D,
as shewn at Figure 4, the clutch G, in this case working behind the roller C, and
having a movable or fixed bracket g, for carrying the roller D.
The whole arrangement before described is such, that on the pipe to be flanged
being put into the head A, and held there, the spindle E, is manipulated by the
handle F1, thus forcing the disc or roller close against the inside end of the pipe, the
external shape of the said roller causing the pipe to take the form or shape of a bell
.month, or nearly so, as shewn at b¹, Figure 1ª. On the bottom roller or disc D, being
manipulated by means of its handle J, it is caused to press against the inside of the
bell mouth end of the pipe and thus effect the flanging of it, as shewn at b², Figure 1*,
the said roller or disc. D, regulating the breadth or diameter of the flange according
to its size and shape. The said rollers may be used in conjunction with one another,
or each separately as desired.
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―
First. The general arrangement and combination of parts constituting the improved
apparatus for flanging.the ends of pipes, substantially as herein before described with
reference to the accompanying drawings.
Second. In the improved apparatus for flanging the ends of pipes the employment
and construction of the head A, with cover A¹, catch a¹, and the guide piece b; all
substantially as and for the purposes hereinbefore described and set forth, with
reference to the accompanying drawings.
Third. In the improved apparatus for flanging the ends of pipes the general
arrangement and construction of spindle E, revolving clutch G and rollers or disc C,

page_text: and D, or the modification as shewn at Figure 4, all substantially as and for the
purposes hereinbefore described and set forth with reference to the accompanying
drawings.
