Improvements in Machinery or Apparatus for Flanging, Recessing, or
otherwise Treating the Ends of Steam Boiler Furnace Flues and
the like.
I, JOHN IRELAND BOOKER, of Tong Road, New Wortley, Leeds, in the County
of York, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to improvements in machinery or apparatus for
flanging recessing or otherwise treating the ends of steam boiler furnace flues and
the like and more especially to that form known as the "bottle-neck"
or inter-
changeable corrugated furnace flue in which the back-end has a surrounding
eccentric flange at right angles to the axis of the furnace flue with the bottom
or lowermost portion recessed or angular thereto, which recessed or angular portion
gradually dies away to a top or uppermost portion parallel to the axis of the
furnace flue.
In accordance with this my said invention I construct a machine or apparatus
of a vertical frame to which is bolted or otherwise secured a projecting anvil or
block having its face suitably built up of interchangeable dies. A sliding tup
or taps actuated by hydraulic or other power works in guides upon the face of
the vertical frame and carries a recessing die preferably built up of interchange-
able segments shaped to form the recessed or angular portion of the "bottle-
neck and a corrugated die or holder adapted to fit the corrugations nearest the
back-end and to hold the furnace flue firm in position upon the anvil during
the operations of recessing flanging and the like. The said recessing and
corrugated dies are respectively arranged to move quadrentially by means of a
hand wheel worm and quadrant thereby facilitating the treatment of the vary-
ing depth of the recessed or angular portion of the back-end of the furnace flue.
A lever fulcrumed at its one end to the vertical frame and connected at its other
end say by means of a toggle piece to an hydraulic or other cylinder carries a
fixed flanging die and an adjustable flanging die actuated by an hydraulic or
other cylinder so that by operating the said fixed and adjustable flanging dies
either simultaneously or consecutively the surrounding eccentric flange at the
back-end of the furnace Hue is formed.
In order to dispense as far as possible with the use of an overhead crane or
equivalent gear I carry the furnace flue to be treated to the anvil of the machine
or apparatus by means of a turn-table having a lever operated by a hand wheel
worm and rack for tilting or placing the furnace flue into position upon the
anvil. The turn-table may work upon an underframe running on rails serving
between the fire for heating the furnace flue and the machine or apparatus.

page_text: Although this my said invention has been described as especially applicable
for the manufacture of the ends of furnace flues of the kind hereinbefore
referred to as "bottle-neck" or interchangeable corrugated furnace flues I wish
it to be understood that the flanging recessing or similar treatment of the ends
of other forms of steam boiler furnace flues and the like may be efliciently per-
formed by the machine or apparatus substantially as hereinbefore set forth.

Improvements in Machinery or Apparatus for Flanging, Recessing, or
otherwise Treating the Ends of Steam Boiler Furnace Flues and
the like.
I, JOHN IRELAND BOOKER, of Tong Road, New Wortley, Leeds, in the County
of York, Engineer, 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 has reference to improvements in machinery or apparatus for
flanging recessing or otherwise treating the ends of steam boiler furnace flues and
the like and more especially to that form known as "bottle-neck "
or inter-
changeable flanged furnace flues in which the back end has a surrounding
eccentric flange at right angles to the axis of the furnace flue with the bottom
or lowermost portion recessed or angular thereto, which recessed or angular portion
gradually dies away to a top or uppermost portion parallel to the axis of the
furnace flue.
bottle-
In accordance with this my said invention I construct a machine or apparatus
of a vertical frame to which is bolted or otherwise secured a projecting anvil or
block having its face suitably built up of interchangeable dies. A sliding tup
or tups actuated by hydraulic or other power works in guides upon the face of
the vertical frame and carries a recessing die preferably built up of interchange-
able segments shaped to form the recessed or angular portion of the
neck" and a corrugated die or holder adapted to fit the corrugations nearest the
back end and to hold the furnace flue firm in position upon the anvil during
the operations of recessing flanging and the like. The said recessing and
corrugated dies are respectively arranged to move quadrentially by means of a
hand wheel worm and quadrant thereby facilitating the treatment of the vary-
ing depth of the recessed or angular portion of the back end of the furnace flue.
A lever fulcrumed at one end to the vertical frame and connected at its other
end say by means of a toggle-piece to a hydraulic or other cylinder carries a
fixed flanging die and an adjustable flanging die actuated by a hydraulic or
other cylinder so that by operating the said fixed and adjustable flanging dies
either simultaneously or consecutively the surrounding eccentric flange at the
back end of the furnace flue is formed.
In order to dispense as far as possible with the use of an overhead crane or
equivalent gear I carry the furnace flue to be treated to the anvil of the machine
or apparatus by means of a turntable having a lever operated by a hand wheel
worm and rack for tilting or placing the furnace flue into position upon the

page_text: anvil. The turntable may work upon an underframe running on rails serving
between the fire for heating the furnace flue and the machine or apparatus.

With reference to the accompanying illustrative sheets of drawings, in which
like references indicate like parts in all the figures. Fig. 1, Sheet 1, is a side
elevation of a machine or apparatus embodying this my said invention, and
Fig. 2, Sheet 1, is a front elevation of the recessing die hereinafter described.
Fig. 3, Sheet 2, is a front elevation of the holding die or gripper hereinafter
referred to whilst Figures 4, 5, 6, 7, 8, 9, 10 & 11, show in side elevation various
forms of dies and grippers. Fig. 12, Sheet 3, shows in sectional elevation the
approximate position of the tools employed in the manufacture of "bottle-neck
flanged furnace flues whilst Fig. 13, shows a modification applicable to the manu-
facture of ordinary flanged furnace flues. Fig. 14, Sheet 4, shows in sectional
elevation a radially adjustable die hereinafter referred to; whilst Figures 15 & 16
show arrangements for treating the ends of furnace flues which are described
later.
Referring to Fig. 1, Sheet 1: -1 is a vertical frame to which is bolted or
otherwise secured preferably at a slight angle a projecting anvil or block 2 having
its face built up of interchangeable dies 3, 3. Sliding tups 4, 4, actuated by
hydraulic or other cylinders 5, 5 slide in guides formed on the face 7 of
the vertical frame 1. The tup
carries a recessing die 4b and the tup 4 carries
a holding die or gripper 4°. The lever 8 is fulcrumed at 9 to the vertical frame 1
and connected to and operated by a hydraulic or other cylinder 8 by means of a
toggle piece 9 and carries a die or radius piece 10 and a flanging die 11 which
latter is operated by a separate hydraulic or other cylinder 11 suitably secured
to and carried by the lever 8. X is a furnace flue under treatment supported in
position by a tilting lever 12 fulerumed at 12ª to a standard 12b fixed on a turn-
table 12 which works upon an underframe 12d running on rails 12ª carried by a
vertically adjustable table 12 actuated by hydraulic or other power. The tilting
lever 12 has a rack 13 which gears with the worm 1:3" on the standard 13b so
as to be capable of adjustment by operating a hand-wheel 13. The standard 14
carried by the turntable 12° has a case 14" within which works a piston block 114b
and roller 14° mounted on a rod 14d connected to and operated by a hand-lever 14°
so that by means of a loose pin fitting in holes 14 in the hand-lever 14° and
curved arm 14 the roller 14° may be suitably adjusted to fit within the end of
the furnace flue. The recessing die 4b (see Figures 1 & 2, Sheet 1, Figures 3, 4,
5 & 6, Sheet 2, and Fig. 12, Sheet 3.) is arranged to move quadrentially by means
of a hand-wheel 15 and rod 15" carried by a bracket 15. The rod 15" operates
the worm 15° which latter gears with a quadrant 15. The holding die or
gripper (shown in all the figures except Fig. 2, Sheet 1) is likewise arranged
to move quadrentially by means of a hand-wheel 16 and rod 16ª carried by a
bracket 16b. The rod 16 operates a worm 16 which latter gears with a
quadrant 16 (see Fig. 3. Sheet 2). The interchangeable die 3, shown in Fig. 1,
Sheet 1, Fig. 12, Sheet 3, and Fig. 14, Sheet 4, is preferably rendered radially
adjustable by means of a projecting arm 17 pivoted to a connecting rod 17° to
which is secured a travelling nut 17, operated by a hand-wheel 17° and screw 17ª,
working upon the bed 17, (see Fig. 1, Sheet 1).
In the manufacture of steam boiler furnace flues of the kind hereinbefore
referred to as "bottle-neck interchangeable flanged furnace flues it is general
to form a plain tube and if desired corrugate the same leaving a projecting plain
portion at the end of the tube which is to be flanged and formed into the "bottle-
neck back end of the furnace flue.
"
Now in accordance with this my said invention I take a furnace flue say after
it has been corrugated and heat the plain projecting portion intended to form
its back end in a suitable fire preferably placed near to the machine or apparatus
in order that the furnace flue may rest upon the anti-friction rollers 128, 121, at
the forked end 121 of the tilting lever 12 (see Fig. 1, Sheet 1). When the
portion to be heated has reached the required temperature say 900 degrees

page_text: Fahrenheit the furnace flue is carried away from the five by the under-
frame 12 and placed in position upon the anvil or block 2 by means of the
tilting lever 12 and turn-table 12, the table 12 being adjusted vertically if
required. The roller 14° is placed within the front end of the furnace flue as
shown in Fig. 1, Sheet 1, in order to retain it in position upon the anti-friction
rollers 128, 12. The holder or gripper 4° is then brought into operation so as
to hold or grip the portion of the furnace flue wall between itself and the inter-
changeable die or dies". It will be seen that the die or dies must correspond
with the particular construction of the furnace flue wall under treatment. The
die or dies 3 are therefore arranged to be interchangeable so that a different die
or dies is or are used for the various constructions of furnace flues. The hold-
ing die or gripper 4° according to my invention is arranged to move quadrenti-
ally as already described with reference to Fig. 3, Sheet 2, so that, for example,
a portion, «, of its face may have corrugations of the Morison" type (see
Figures 3 & 4, Sheet 2,). and a portion, b, corrugations of the "Fox" type (see
Figures 3 & 5, Sheet 2) and other portions may have other forms of corrugations,
whilst a portion, c, may be made plain (see Figures 3 & 6, Sheet 2). If a furnace
flue having corrugations of the Morison" type be under treatment the holding
die or gripper 4 is adjusted by means of the hand-wheel 16 worm 16° and
quadrant 1 so that the portion, «, of its face having the "Morison" type of
corrugations thereon may be brought into position. Thus when the holding die
or gripper 4° is caused to descend the furnace flue wall will be gripped between
the portion, a, of its face and the interchangeable die or dies 3. For the treat-
ment of furnace flues having the "Fox" type of corrugations the portion, b, of
the holding die or gripper 4 will be adjusted to the required operative position
and for the treatment of plain furnace flues the face, c, will be brought into its
active position, and so on. The recessing die 4 is then brought into operation
so that its face 4b will recess and form the deepest portion Y of the furnace flue X
which is then turned by any convenient means (the holding die or gripper 4°
being in the meantime released) so that a further portion of its back end is brought
uppermost into position. The recessing die 4b is then adjusted by means of the
hand-wheel 15 worm 15° and quadrant 15 so that a shallower portion 42 of its
face is brought into operation, the holding die or gripper 4 being again lowered
so as to hold or grip the furnace flue wall, and the recessing operation continued.
It will be seen that the varying depth of the "bottle-neck portion of the back
end of the furnace flue is formed by suitably adjusting the recessing die 4, the
deepest portion of its face, 41, being first used after which a shallower portion,
say 4b3, is used whilst the shallowest or level portion, 43, serves to form that
portion of the bottle-neck" which merges into the wall of the furnace flue,
(see Fig. 2, Sheet 1 and Figures 3, 4, 5, & 6, Sheet 2). When the recessed
portion of the bottle-neck has been formed the lever S is actuated so that
the die 11 will turn up and form the flange Z of the furnace flue. As the lever 8
is caused to ascend still further the interchangeable die or radius piece 10 shaped
so as to suit the radii 7 & 72 is brought up to the furnace flue end and in con-
junction with the recessing die 4b enables a true bend or curve to be made, (see
Fig. 12, Sheet 3). The die 11 is then or may be caused to press or hammer the
flange Z between itself and say the recessing die 4 and interchangeable die 3 by
means of a hydraulic or other cylinder 11", and so complete the operation.
In order to admit of the treatment of furnace flues having different dimen-
sions of bottle-neck back ends and also of furnace flues having other forms
of back ends I preferably arrange the interchangeable die 3 as shown in Fig. 1,
Sheet 1, Fig. 12, Sheet 3, and Fig. 14, Sheet 4, so that by operating the hand-
wheel 17 the die is radially adjusted either for the manufacture of bottle-neck "
back ends as illustrated in Fig. 1, Sheet 1, and Fig. 12, Sheet 3, and in dotted
lines in Fig. 14, Sheet 4, or for the manufacture of ordinary flanged furnace
flues as shown in full lines in Fig. 14, Sheet 4.
"
In some cases it may be desired to add a corrugation or corrugations at the

page_text: "
back or front end of a furnace flue and if the rolls of the corrugating mill be not
of a sufficient length to admit of this, such extra corrugation or corrugations may
be added by my improved machinery or apparatus. Fig. 9, Sheet 2, shows the
holding die or gripper 4° formed to suit a furnace flue having "Fox" corruga-
tions whilst the die or former 4' is shaped to form a Morison " corrugation.
Fig. 8, shows a holding die or gripper 41 of the "Fox" type having a Morison"
corrugation so as to be adapted for holding or gripping a furnace flue which may
have been dealt with by the die or former 4. Fig. 11, shows the holding die
or gripper 4 of the "Morison" kind with the die or former 43 for forming
corrugations of the " Fox" type say in conjunction with a die 31 as shown in
Fig. 15, Sheet 4. The holding die or gripper 43 as shown in Fig. 10, has corru-
gations of the barrel"
type whilst the die or former 43 is shaped to form "Fox"
corrugations. Fig. 7 shows a holding die or gripper 4+ for holding or gripping a
furnace flue that may have been treated by the die or former 43.
Fig. 16, Sheet 4, illustrates a holding die or gripper 4° and a die 4b adapted
for flattening or straightening the end of a furnace flue in conjunction with
the die 31.
Although this my said invention has been described as specially applicable for
use in the manufacture of steam boiler furnace flues of the kind herein before
referred to as "bottle-neck" interchangeable flanged furnace flues I wish it to
be noted that other operations relative to the treatment of the ends of other
forms of steam boiler furnace flues and the like may be efficiently performed by
the machine or apparatus substantially as herein set forth.
