Improved Machinery or Apparatus for Flanging, Expanding, and
Recessing the Ends of Flues, Tubes, and like Articles of Metal,
We, WILLIAM DEIGHTON, of One Ash, Hall Lane, New Leeds, Leeds, in the
County of York, Engineer, and THE DEIGHTON FLUE AND TUBE Co., LTD., of
Vulcan Works, Pepper Lane, Leeds, in the County of York, Engineers, do hereby
declare the nature of this invention to be as follows: —
Our present invention relates to improved machinery or apparatus for flanging
expanding, and recessing the ends of flues, tubes, and like articles of metal.
At one end of a base or bed plate we erect on slides or grooves, two adjustable
vertical standards or uprights, connected at the top and bottom by cross pieces;
the whole being free to be moved in a horizontal direction by means of a screw
and hand wheel, or other suitable appliance. Between the vertical standards or
uprights are placed in grooves or guides, two headstocks (one above the other),
each capable of being raised or lowered independently of the other, by means of
hydraulic rams connected to the bottom or underside.
To the top or upper headstock is attached the flanging and expanding apparatus,
which consists of an outer double armed bracket free to move in a horizontal direc-
tion in grooves or slides on the underside of headstock, and an inner frame pivoted
at each end between the arms of the said bracket, with extended part in the centre
carrying a loose pulley or roll.
The arms of the outer bracket are connected by rods to a 'hydraulic ram, secured
in a horizontal position to the upper or top headstock; the centre of the inner
pivoted frame being connected by means of a rod to an oscillating hydraulic ram,
which is secured in a horizontal position to the said outer bracket. The arrange-
ment being such that the outer and inner brackets can be moved independently,
the outer in a horizontal direction, and the inner in a circular direction through
an angle of 90 degrees, or from a vertical to a horizontal position, and vice versa;
or simultaneously, both in a horizontal direction.
To the bottom headstock are attached two guide rolls, both adjustable vertically,
and horizontally, and between them is placed the recessing roll, mounted on an
adjustable vertical spindle connected at right angles to a hydraulic ram, secured
in a horizontal position to the lower part of the bottom headstock.
The before mentioned recessing roll also acts as the flanging block, and expand-
ing block roll.
At the opposite end of the base or bed plate is mounted a revolving table, upon
which the flue or tube to be operated upon is placed; suitable clamps being
provided to hold it in position, and bevel gearing on the underside conveys to it
the required revolving motion.
The method of flanging is as follows:-a flue or tube after being heated is
placed in a vertical position upon the revolving table and secured thereto by the
clamps, the end requiring to be flanged being placed uppermost; the vertical
standards and headstocks having been previously adjusted; the lower headstock

to such a position as will allow the peripheries of the guide rolls to be brought
to bear against the top outside part of the tube being operated upon, and keep it
perpendicular.
The flanging block roll being independently adjusted to a position corresponding
with the depth of the flange required to be given to the said flue or tube.
The bracket is then placed in position, that is to say-the extended part of
the inner pivoted frame carrying the loose roll or pulley is placed in a vertical
position close to the inside edge of the tube or flue being operated upon, the
pivoted arms extending clear of same being on the outside.
Motion is now given to the revolving table, and as the flue or tube revolves the
outer double armed bracket is held stationary by the rods connecting it to the
hydraulic ram, and the inner pivoted frame carrying loose roll is drawn gradually
by means of the oscillating hydraulic ram secured to the outer bracket, from a
vertical position through an angle of 90 degrees to a horizontal position, thereby
bending the edge of the flue or tube over the flanging block roll placed on the
outside.
To expand the end of a flue or tube the machine is adjusted to relatively the same
position as in the previous case, with the exception that the outside flanging block
roll is not brought close up to the outside of the flue or tube, but placed at a
distance from the side corresponding to the required enlargement of the end of
the flue or tube; and the movement of the double armed bracket and pivoted
frame carrying loose roll, is made in this case simultaneously in a horizontal
direction, so that the end of the flue or tube as it revolves is gradually drawn
outward, until it comes in contact with the outside block roll.
In recessing the end of a flue or tube the pivoted frame carrying loose roll is
held stationary in a vertical position inside the flue or tube, at a distance from
the edge corresponding to the depth of recess required, and the outside roll is
brought up to the outside edge and by means of the hydraulic ram to which it is
connected, forces the end of the flue or tube as it revolves up against the roll
inside.
All the rolls are interchangeable, and may be altered to suit requirements.

Improved Machinery or Apparatus for Flanging, Expanding, and
Recessing the Ends of Flues, Tubes, and like Articles of Metal.
We, WILLIAM DEIGHTON, of One Ash, Hall Lane, New Leeds, Leeds, in the
County of York, Engineer, and THE DEIGHTON FLUE AND TUBE Co. LTD., of
Tulcan Works, Pepper Lane, Leeds, in the County of York, Engineers, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
Our present invention relates to improved machinery or apparatus for flanging,
expanding, and recessing the ends of flues, tubes, and like articles of metal.
At one end of a base or bed plate we erect on slides or grooves, two adjustable
vertical standards or uprights, connected at the top and bottom by cross pieces;

page_text: the whole being free to be moved in a horizontal direction by means of a screw
and hand wheel, or other suitable appliance. Between the vertical standards or
uprights are placed in grooves or guides, two headstocks (one above the other),
each capable of being raised or lowered independently of the other, by means of
hydraulic rams connected to the bottom or underside.
To the top or upper headstock is attached the flanging and expanding apparatus,
which consists of an outer double armed bracket free to move in a horizontal direc-
tion in grooves or slides on the underside of headstock, and an inner frame pivoted
at each end between the arms of the said bracket, with extended part in the centre
carrying loose pulley or roll.
The arms of the outer bracket are connected by rods to a hydraulic ram, secured
in a horizontal position to the upper or top headstock; the centre of the inner
pivoted frame being connected by means of a rod to an oscillating hydraulic ram,
which is secured in a horizontal position to the said outer bracket. The arrange-
ment being such that the outer and inner brackets can be moved independently,
the outer in a horizontal direction, and the inner in a circular direction through
an angle of 90 degrees, or from a vertical to a horizontal position, and vice versa;
or simultaneously, both in a horizontal direction.
To the bottom headstock are attached two guide rolls, both adjustable vertically,
and horizontally, and between them is placed the recessing roll, mounted on an
adjustable vertical spindle connected at right angles to a hydraulic ram, secured
in a horizontal position to the lower part of the bottom headstock.
The before mentioned recessing roll also acts as the flanging and expanding
block roll.
At the opposite end of the base or bed plate is mounted a revolving table, upon
which the flue or tube to be operated upon is placed; suitable clamps being
provided to hold it in position, & bevel gear upon the underside conveys to it
the required revolving motion.
In the accompanying drawings.
Fig 1, Sheet 1 is a side elevation of our improved apparatus.
Fig 2, Sheet 2 is an enlarged view (end) of flanging & expanding apparatus.
Fig 3, Sheet 2 is a part sectional elevation of same.
The method of flanging is as follows:-a flue or tube a, after being heated at
the end to be flanged is placed in a vertical position upon the revolving table b
and secured thereto by the clamps c, c, c, the end to be flanged being placed upper-
most; the vertical standards d, and headstocks e, e', having been previously ad-
justed, the lower headstock e', to such a position as will allow the peripheries of
the guide rolls f, to be brought to bear against the top outside part of the tube a,
being operated upon, and keep it perpendicular. The flanged block roll g, being
independently adjusted to a position corresponding with the depth of the flange
required to be given to the said flue or tube a.
The bracket h, is then placed in position-that is to say-the extended part
of the inner pivoted frame h¹, carrying the loose roll or pulley j, is placed in a
vertical position close to the inside edge of the tube or flue a, being operated
upon the pivoted arms k, k¹, extending clear of same being on the outside.
Motion is now given to the revolving table b, and as the flue or tube a, revolves
the outer double armed bracket h. is held stationary by the rods 7, connecting it
to the hydraulic ram m, and the inner pivoted frame h¹, carrying loose roll j, is
drawn gradually by means of the oscillating hydraulic ram n, secured to the
outer bracket, from a vertical position through an angle of 90 degrees to a
horizontal position thereby bending the edge of the flue or tube a, over the
flanging block roll g, placed on the outside, see Fig. 3.
To expand the end of a flue or tube the machine is adjusted to relatively the
same position as in the previous case, with the exception that the outside flanging
block roll g, is not brought close up to the out side of the flue or tube በ, but
placed at a distance from the side corresponding to the required enlargement of
the end of the flue or tube; and the movement of the double armed bracket h,

page_text: and pivoted frame h, carrying loose roll j, is made in this case simultaneously
in a horizontal direction, so that the end of the flue or tube a, as it revolves is
gradually drawn outward until it comes in contact with the outside block roll g.
In recessing the end of a flue or tube the pivoted frame h¹, carrying loose roll j,
is held stationary in a vertical position inside the flue or tube a, at a distance
from the edge corresponding to the depth of recess required, and the outside roll g
is brought up to the outside edge and by means of the hydraulic ram p, to which
it is connected forces the end of the flue or tube as it revolves, up against the roll j,
inside.
All the rolls are interchangeable and may be altered to suit requirements.
The standards d, are adjusted horizontally upon the bed plate r, by means of the
hand wheels, and screws, and the headstocks e, e¹ are raised and lowered as
required by means of the hydraulic rams t.
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. In a machine for flanging, expanding, and recessing the ends of flues, tubes,
and like articles of metal, the combination and arrangement upon a base or bed
plate of adjustable standards carrying an upper and a lower adjustable head-
stock, as described and illustrated by the accompanying drawings.
2. In a machine for flanging, expanding, and recessing the ends of flues, tubes,
and like articles of metal, the combination and arrangement of an outer double
armed bracket and inner frame, carrying loose pulley, with an adjustable head-
stock, as described & illustrated by the accompanying drawings.
3. The general arrangement and construction of improved machinery or
apparatus for flanging, expanding, and recessing the ends of flues, tubes, and
like articles of metal, as described and illustrated by the accompanying drawings.
