Improvements in Machinery and Apparatus for the Manufacture of
Corrugated or other Sectional Tubes..
I WILLIAM DEIGHTON of 13 Hyde Terrace Leeds in the County of York,
Engineer do hereby declare the nature of this invention to be as follows:-
Improvements in machinery and apparatus for the manufacture of corrugated or
other sectional tubes.
My invention has reference to improvements in machinery and apparatus for the
manufacture of tubes, or fire-boxes, circular in cross section, corrugated or other
varying section longitudinally, and which may be used as internal fire-boxes or
flues in steam boilers or for other purposes.
My improved machinery or apparatus consists of a pair of suitably mounted
rolls with guide rolls on each side, the said rolls having equal or unequal corru-
gations or other desired section turned on them and in all cases their peripheries
being at right angles to the axis of the roll.
My first improvement consists in the method of raising and lowering the bottom
roll. In or under the foot of each standard or housing carreying the two maine
rolls, I fix an hydraulic cylinder and ram or other simular imotor, which actuates
the "chucks" or "bearers" in which the brasses and necks of the bottom roll are
carried. The hydraulic ram is used to raise the "chucks or "bearers" with the
bottom roll against a projecting piece cast on the inner side of standard or housing
legs, beyond which they cannot be raised, distance pieces being used to suit the
thickness of plate used in the tubes being rolled.
"
My second improvement consists of casting on the inner side of the logs of the
standard or housings a projecting piece, in such manner and position that when the
"chucks" or "bearers carreying the bottom roll is being raised they come in
contact with it, in this position the bottom roll will just touch the top roll, by this
arrangement the bottom roll can be so adjusted and fixed in its relation to the top
roll as to suit any thickness of plate forming the tube or flue, so that no undue
pressure or thinning of the tube or flue can take place during the process of
corrugating the top roll by preference having a fixed vertical position.
My third improvement consists in the method of constructing one of the
standards or housings when it is desired to keep the top roll a fixture (vertically
and horizontaly) and to facilitate the placing of the tube in position for corru-
gating and removal of the same after corrugating from the top roll which it
surounds. I make one of the housings or standards in two parts, on each side of

page_text: the lower or fixed part of housing carreying the bottom roll I fix a trunnion on
which the upper part of housing may be raised or lowered from the horizontal to
the vertical and vice versa and rotating through '90 degrees more or less. To the
said upper or moveable part of housing I fix a pinnion wheel rotating on the said
trunnion, the wheel may be geared to a rack or worm gearing or other suitable
mechanical appliances for rotating the upper part of "housing." To facilitate
the rotating of the upper part of "housing," it is desireable to remove the brass
from off the top roll neck and to replace the same when required, to this end
I attach by suitable means to the said moveable or upper part of housing an
hydraulic motor or other suitable appliances which may withdraw and replace
the top roll brass as required, thus leaving the said housing freedom to rotate as
described. In a modification of, the method of removing the top roll in combination
with the improvements one and two" I remove the top roll end wise through
one of the housings or standards thus leaving a clear space between the two
"housings" for the better handling of the tube, the roll being carried on two or
more sliding bearings.
"

My fourth improvement is contained in the method of mounting and working
the guide rolls on each side of the main rolls. I mount the guide rolls at their
ends on rocking leavers, the "pivots or trunnion being by preference secured to
the inner side of "housing," the said rolls moveing radialy and simultaneously,
towards the main rolls, the side rolls may be plain or corrugated to suit the section
on main rolls, the rocking leavers may be worked by any suitable mechanical
means or appliances such as worm gearing &c.
My fifth improvement consists in the method of rolling (in combination with my
improvements 1, 2, 3 and 4 of corrugated or other sectional tubes or flues with
their ends flanged outwardly at right angles to the axis of the tube or flue. The
main rolls are suitabley turned in their longitudinal section, by the adjustment of
the bottom roll the tube may be first flanged and then corrugated or may be
flanged and corrugated at the same time on the inner sides of housings
standards may be placed moveable rollers actuated by hydraulic or other power
for the purpose of, more perfectléy setting up the flanges at right angles to the axis
of the tube or flue.

Improvements in Machinery and Apparatus for the Manufacture of
1.
Corrugated or other Sectional Tubes.
I, WILLIAM DEIGHTON, of 13 Hyde Terrace, Leeds, in the County of
Yorkshire, 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:-
My invention has reference to improvements in machinery, or apparatus, for the
manufacture of tubes or fire boxes, circular in cross section, and of corrugated or
other varying section longitudinally, and which may be used as internal fire boxes,
or flues, in steam boilers, or for other purposes.

Prior to this invention it has been proposed by Samson Fox and others to construct
flue mills comprising a pair of suitably, mounted rolls, with guide rolls on each side,
the said rolls having equal or unequal corrugations, or. other desired section, turned
on them, likewise to raise and lower the bottom rolls of such Que mills in order to
leave more or less space between the rolls as may be desired for t
be desired for the particular flue or
tube it is intended to make.

It has also been proposed to have the top bearing and part of the housing at one
end of the top roll removable for the purpose of enabling the partially formed flue or
tube to be placed upon, and when finished to be withdrawn from such roll, and the
requisite movements of the parts have been secured by the use of links, screw and
rack gear, and by hydraulic power, and I make no broad claim to any of the above
features except they be arranged and combined in the manner, hereinafter specifically
described and claimed.
"
My first improvement consists in the method of raising, and lowering the bottom
roll. In, or under the foot. of. each housing or standard carrying the two main
rolls, I fix a hydraulic ram, which actuates a chuck or bearer, on which the brasses
and necks of the bottom roll are carried. The hydraulic rams are used to raise
the said chucks or bearers. carrying the bottom roll, against a projecting piece cast
on the inner side of standard or housing legs, beyond which they cannot be
raised, distance pieces being used to suit the thickness of plate of tube. being
5. rolled.

"
My second improvement consists of casting on the inner side of the legs, of
standards or.housings, projecting pieces in such a manner, and position that when
the chucks or bearers carrying the bottom roll are being raised, they come in
contact with them; in this, position. the bottom roll will just touch the top roll.
By this arrangement the bottom roll can be so adjusted and fixed in its relation
to the top roll, as to suit any thickness of plate, forming the tube-or flue, so that
no undue pressure or thinning of tube. or flue can take place during the process of
corrugating. The top roll (by preference) has a fixed vertical and horizontal
position.
My. third improvement consists in the method of constructing one of the
, housings or standards. When it is desired to keep the top roll a fixture,
(vertically and horizontally) and to facilitate the placing of the tube or flue in
position for corrugating, and removal of the same after corrugating from the said
top, roll which it surrounds. To this end, I make one of the housings or standards
in two parts. On each side of the lower or fixed part of housing, carrying the
bottom roll, I fix trunions on which the upper-part, of housing may be raised or
lowered from the horizontal to the vertical, and vice versa, and rotating through
90 degrees more or less. To the upper or movable part of housing I fix a pinion
wheel, which rotates on the said trunions. The wheel may be geared to a rack
for worm gearing, or other suitable mechanical appliance for rotating the upper
part of, housing.
"
To facilitate the rotating of the said upper part of housing it is desirable to
remove the brass from off the top roll neck and to replace same when required.
For this purpose.I attach, by suitable-means to the said movable or upper part of
housing a hydraulic motor or other suitable appliance which may withdraw and
replace, the top.roll. brass: as required thus leaving the top part of housing free to
rotate as desired..
My fourth improvement has reference to the method of mounting and working
the guide rolls. on each side of the main rolls. I mount, the guide rolls at their
ends on rocking levers, the pivots or trunions-being by preference secured to the
inner side. of housings, the said-guide rolls moving radially and simultaneously
towards the main, rolls. The said guide; rolls may be plain- or corrugated to suit
the section of main rolls.
-
The rocking levers may be worked by any suitable mechanical means or
appliance such as worm gearing or otherwise.
My fifth improvement consists in the method of rolling (in combination with any
of my improvements 1, 2, 3 & 4, the sectional tubes with their ends flanged
outwardly at right angles to the axis of the tube or-flue..
By the adjustment of the bottom roll the flanges may be first formed, and the
flue afterwards corrugated, or the flue may be flanged and corrugated at the
same time.
しか
On the inner side of the housings or standards, I place movable rollers actuated

Fig. 3. Sheet 2. a sectional elevation on the line A. B. Fig. 5..
Fig. 4. an end elevation.
Fig. 5.,Sheet 3. a side elevation.
1 and 2 Figs. 1 and 2 are the main rolls having corrugations of the desired.
section turned on their peripheries at right angles to the axes of the rolls. 3. 3. are
the guide rolls.
The top main roll 1 has by preference a fixed horizontal, and vertical position,
and the bottom main roll 2 is by preference subject to a vertical movement. In or
under the foot of each housing or standard 5. 5. carrying the two main rolls 1.,
and 2 I fix a hydraulic ram 6, 6, or other similar motor, which actuates chucks or
bearers 7. 7. on which the brasses, 8. 8 and necks of the bottom roll 2 are carried.
The hydraulic rams 6, 6, raise the chucks or bearers 7. 7. carrying the bottom
roll 2, in a vertical direction. Projecting pieces 10 10 are cast on the inner sides
of the standards or housings 5. 5. beyond which the before mentioned chucks or
bearers 7. 7. cannot be raised. Distance pieces 11 11 being inserted to correspond
with the thickness of plate from which the flue or firebox is being rolled. The
arrangement being such, that when the chucks or bearers 77 carrying the bottom
roll 2, are being raised (the distance pieces 11 11' having been inserted) they come
in contact with the before mentioned projecting pieces 10, 10, and their further.
vertical movement is arrested. In this position the bottom roll 2, will have been
brought to within the required distance of the top roll 1. By this arrangement
the bottom roll 2, can be so adjusted and fixed in its relation to the top roll 1; as
to suit any thickness of plate required to be used in the manufacture of a flue or
tube, and no undue pressure or thinning of the flue or tube can take place during
the process of corrugating. For the purpose of placing a tube in position on the
top main roll 1, (for corrugating, and removing it after it has been corrugated,
from the said top roll 1 which it surrounds) one of the housings or standards
constructed in two parts. On either side of the lower part, which is fixed, and
carries the movable bottom main roll 2, I place trunions 12, 12, upon one of which
a pinion wheel 13 rotates; the said pinion wheel 13 being geared to a rack
gearing 14, and hydraulic motor; and by means of which the upper part of the
standard or housing 54, may be raised or lowered from a horizontal to a vertical
position and vice versa, the movement being through 90 degrees more or less.
Before rotating the upper part of the standard or housing 5ª it is necessary to,
remove the pin 28 Fig. 5. and the brass bearing 15 and afterwards replace same
when required. For the purpose of removing the brass bearing 15 I attach by
suitable means to the movable or upper part of housing or standard 5ª a hydraulic
motor 16 or other suitable appliance which withdraws and replaces the top roll
brass bearing 15 as required thus leaving the upper movable part of the standard
or housing 5 free to rotate as required.
is
The guide rolls 3, 3 on each side of the main rolls 1 and 2 are mounted at their
ends on rocking levers 18 the pivots or trunions 20 being by preference secured to
the inner side of housings 5. 5. ; the said guide rolls 3. 3. (which may be either
plain or corrugated to suit the section 'of main rolls 1 and 2) moving radially and
simultaneously towards the main rolls 1 and 2.
The rocking levers 18 are controlled by hydraulic rams 21 or other suitable
appliance.
Fig. 6 is an enlarged side view and Fig. 7 enlarged plan of flanging rollers.
'
In some cases the ends of the flues or fire boxes are required to be flanged and
for this purpose I arrange movable frictional rollers 22 Figs. 5. 6. 7. actuated by
hydraulic motor 23 (or other suitable appliance) and levers 24 carried by
brackets 25 attached to the outside of housings or standards 5. As the flue or

page_text: fire box being operated upon 26 rotates in the mill the bydraulic motor 23 when
required is caused to actuate holder carrying the frictional rollers 22 by means of
the levers 24 (or other suitable apparatus) moving the said frictional rollers 22 up
against the outside edge of the flue or fire box 26 thereby setting up the edges of
same as desired to form the flanges 27.
It will be obvious that the mill may be driven by any suitable gearing.
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 :-
1. In machinery or apparatus for corrugating flues or fireboxes, the combination
and arrangement of the parts, in the manner, and for the purpose hereinbefore
described, with reference to the accompanying drawings Figs. 1 to 7.
2. In machinery or apparatus for corrugating flues or fireboxes, the combination
and arrangement of hydraulic rams, for raising and lowering the bottom roll, the
upward motion of such rams being limited by projecting pieces upon the housings
as herein before described with reference to the accompanying drawing
3. In machinery or apparatus for corrugating flues or fireboxes, the combination
and arrangement of projecting pieces on the housings or standards, distance pieces,
and chucks or bearers, in the manner, and for the purposes as herein before
described with reference to the accompanying drawings.
4. In machinery or apparatus for corrugating flues or fireboxes, the combination
and arrangement of one of the housings in two parts, the upper part being made
movable, upon its trunnions and carrying hydraulic apparatus capable of removing
and replacing the bearing as and for the purposes herein before described, with
reference to the accompanying drawings.
5. In machinery or apparatus for corrugating flues or fire boxes, the combination
and arrangement of rollers for flanging the ends of flues or fireboxes, as herein-
before described, with reference to the accompanying drawings.
