Improvements in Machinery or Apparatus for Flanging the Ends of
Steam Boiler Furnaces or Flues.
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:-
My present invention has reference to certain improvements in machinery or
apparatus for forming the reverse or wing flanges of steam boiler furnaces or flues,
and has for its object the production of such furnaces or flues with flanges, in a
more economical and rapid manner than heretofore.
For this purpose, upon a bed plate, carried by a circular block or pillar mounted
upon a foundation plate, is arranged a number of flanging blocks, to suit the
diameter of the furnace or flue, and the radii and contour of the reverse or wing
flanges required; and at a convenient distance and centrally with the face I fix, by
preference, to the before mentioned bed plate, a horizontal hydraulic ram the end
of which is provided with a laminated spring, or other suitable appliance, for the
purpose of gripping the outside of the furnace, or flue, when placed vertically in
position upon the bed.plate, and holding it secure against the blocks.
Upon a movable carriage travelling on circular guide rails partly round the bed
plate, and driven in any suitable manner (as for instance by a worm and shaft from
the centre circular block or pillar) is mounted a steam hammer, the head or cylinder
of which may be adjusted in a horizontal direction as required.
At a point about in line with the bed plate, I fix to the steam or other power
hammer standard, in any convenient manner (as for instance by bolts and nuts) a
horizontal hydraulic or other power ram.
A furnace or flue after being heated to a suitable temperature, and partly
flanged, is placed in a vertical position upon the blocks which are arranged upon
the bed plate, the outside configuration of the said blocks corresponding to the
inside form & radii of the wing or return flanges. The hydraulic or other power
ram carrying the laminated spring or other suitable arrangement is then brought
up to the outside of the bottom or unflanged part of the furnace, and binds it up
against the blocks, thereby holding it securely in position for being operated upon;
the top or flanged portion being at the same time placed immediately under the
steam or other power hammer, which, by a number of sharp blows bends the
flanged or wing portion over the radial blocks, the hammer with ram and carriage
being moved as required. Swaging tools of various forms may be used when
required, the hydraulic or other power ram being brought into operation
simultaneously to hold the swages and to trim up the flanges to the required radii
and contour.
As an alternative method, the base plate carrying the flanging blocks and flue
made be made to revolve by suitable appliances together with the gripping arrangé-
ment, the standards or legs carrying the horizontal adjustable steam or other
hammer, and horizontal or inclined ram being made adjustable on their bed plate..
One or more such adjustable hammers and rams may be used.
Swages of various forms may be used in connection with hammer and ram if
desired.
When it is required to flange the end of a flue, or furnace, to the shape or con-
figuration known to the trade as "bottle neck," or "interchangeable," (that is
having an eccentric flange at right angles to the axis of the flue with variable

page_text: depth of necking) I employ a hydraulic ram, the bead of which carries a revolving
punch of the requisite shape or form, provided with a locking arrangement, which
is used in connection with a movable block, so formed as to receive the punch. By
the side of the movable block is placed a hydraulic ram for the purpose of turning
the end flange square up against the side of the revolving punch.
The method of operation in this case is as follows: A flue or furnace after
being heated to a suitable heat is placed in a horizontal position with the end to bu
flanged upon the movable block, the other end being carried by an ordinary
arrangement for giving it a revolving motion as required. The punch is then
brought down until it comes in contact with the end of the flue or furnace to be
flanged, the said flue or furnace being gradually revolved until it assumes the
required shape or form all the way round.
The revolving punch is then kept down, holding the recessed part secure i
in the
movable block, the horizontal rain being then used to square up the end of the
furnace against the side of the punch, and at right angles to the axis of the furnace;
after which the said furnace is gradually revolved, and the operation repeated all
round the end of the furnace.

Improvements in Machinery or Apparatus for Flanging the Ends of
Steam Boiler Furnaces or Flues.
I WILLIAM DEIGHTON of 13 Hyde Terrace 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:
My present invention has reference to certain improvements in machinery or
-apparatus for forming the reverse or wing flanges and other form of flanges of
steam boiler furnaces or flues and has for its object the production of such
furnaces or flues with flanges in a more economical and rapid manner than
.heretofore.
The form of improved apparatus and the construction and arrangement of the
parts connected with then and the method of working the same will be better
understood by reference to the accompanying explanatory drawings of which
Eig. 1 and 2 Sheet 1 are respectively clevation and plan.
Fig. 3 and 4 are respectfully elevation (half in section) and plan of same.
Fig. 5 and 6 Sheet 3 are respectfully elevation and plan.
Fig. 7 is a side view of standard head and horizontal punch.
Fig. 8 is a front elevation of horizontal punch and connections.
Fig. 9 and 10 are end views of punch.
Fig. 11. 12 and 13 are plan and end views of one form of "swage."
In the drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
Upon a bedplate A (Fig. 1.) carried by a circular block or pillar B (which
pillar may be carried to any desired height and on which may be fitted, fixed or
adjustable arms "" for guiding the flue or firebox to a true vertical position)
mounted upon a foundation plate "c" are arranged diameter block D and flanging
blocks D to suit the diameter of the furnaces or flues and the radii and contour of
_the reverse or wing flanges required, and at a convenient distance aud centrally
with the face I fix by preference to the before mentioned bedplate A a horizontal
hydraulic or other power ram E the end of which is provided with a laminated
spring or other suitable appliance F for the purpose of gripping the outside of the

page_text: flue G when placed vertically in position upon the bedplate A and holding it secure
against the block D. Upon a moveable carriage H travelling on circular guide
rails J fixed partly round the bed plate A. and driven in any suitable manner (as
for instance, by worm and wheel K from the centre circular block or pillar B) is
mounted a steam hydraulic, or other power hammer L the head or cylinder of
which may be adjusted in a horizontal direction as required (as for instance by
hand wheel and screw "n"). At a point about in line with the bedplate A. I fix
to the steam or other power hanımer standard O in any convenient manner (as for
instance by bolts and nuts) a horizontal or inclined hydraulic or other power
ram M. A furnace or flue G after being heated to a suitable temperature and
partly flanged (to suit tube or other plate) is placed in a vertical position upon and
around the blocks D. D' which are arranged upon the bedplate A the outside
configuration of the blocks D. D' corresponding to the inside form and radii of the
wing or reverse flange of flue G. The hydraulic or other power ram E carrying
the laminated spring F or other suitable appliance, is then brought up to the
outside of the bottom or unflanged part of the flue G and binds it up against the
blocks D, thereby holding it securely in position for being operated upon, the partly
flanged portion being at the same time placed immediately under the steam or other
power haminer or hammers L which by a number of sharp blows or pressure
(preferably on "swages" _N) bends the wing portion of flue over the radial
blocks D'. The hammer L with ram M and carriage H being moved as required.
Swaging" tools N of various forms and size may be used as and when required
the hydraulic or other power ram M being brought into operation simultaneously
to hold the "swages" and to sett up the flanges to the required radii and contour.
One or more such radial carriages and appliances may be used if desired.
66
As an alternative method (Fig. 3 and 4 Sheet 2) the bedplate A carrying the
diameter blocks D and blocks D and flue G may be made to revolve (on friction
balls or rollers fitted on block B) by any suitable appliances (such as at m) together
with the gripping arrangement E. The standard or leg O carrying the horizontally
adjustable steam or other power hammer L and horizontal or inclined ram M being
made fixed or adjustable on their bedplate P. One or more such adjustable hammer
and rams may be used, by preference two (one on each side of flue) acting simul-
taneously. "Swages" N of various forms and size may be used in connection
with the ram and hammers M and L, as desired. The diameter and flanging
blocks D. D' may be in one, two, or more than three pieces as shewn.
"
When it is required to flange the end of a flue or furnace to the shape or
configuration known to the trade as "bottle neck or "interchangeable" G¹ (that is
having an eccentric flange at right angles to the axis of the flue with variable
depth of necking G2 (see Fig. 5 and 6 Sheet 3) I employ a hydraulic or other power
ram W mounted on standard O the head S of which carries by preference a
revolving punch S' of the requisite shape or form (suitably guided and provided
with a locking arrangement T) which is used in connection with a block or die so
formed as to receive the punch S', the said block or die R being fitted into a
projecting horn or anvil V which also carries friction rollers "g" fitted on elastic
or spring bearings for relieving and easy turning of the flue G', the said horn or
anvil V may be secured by sutable means to standard O or otherwise. By the side
of the moveable block or die R is placed a hydraulic or other power ram or
rams YY for the purpose of turning up the end flange Z square against the
side of the revolving punch S¹. The method of operation in this case is as
follows.
A flue or furnace G' after being heated to a suitable heat is placed in a horizontal
position with the end to be flanged upon the block R the other end being supported
by an universal clutch "A" carried by an adjustable headstock "" with
longitudinal movement by hydraulic ram "c or may be supported by any other
suitable apparatus for giving the flue G₁ a revolving motion and to facilitate its
removal as required.
22
The punch S' is then brought down until it comes in contact with the end of the

page_text: flue or furnace G¹ to be flanged, the said flue G¹ being gradually revolved until it
assumes the required shape or form all the way round. The revolving punch
(when required) is then kept down, holding the recessed part secure in the die R.
The horizontal ram Y and Y' being then used to square up the end 7 of the flue G¹
against the side of the punch S' and at right angles to the axis of flue. As one
alternative to the revolving punch S₁ for flanging I may use with the ram W and
head S (see Fig. 7 and 8 Sheet 4) and sliding in the same horizontally at right
angles to the longitudinal axis of flue G₁ a metallic bar or punch S² preferably of
varying section and length. The end of the bar or punch being carried by
moveable suspended hydraulic cylinder and rams or spiral springs "d" or other
suitable appliances, so that the punch S may be maintained in vertical contact in
the head S of ram W.
The supports "e" carrying the power cylinder "d" or spiral springs or other
appliances attached to ends of punch S' may be fixed to standard-O or fixed in any
other convenient way. The method of operating in this case is identical with
previous one the revolving punch S' being substituted by moveable horizontal
punch S. The above machines may be constructed in such manner that the flue is
held and turned in a vertical position and the punches are placed and worked
horizontally.
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 combination of adjustable power tools practically at right angles
to each other mounted on a carriage for flanging the reverse or wing flanges
of flues or fireboxes substantially as and for the purpose as herein before
described.
Second. The combination of a central pillar guide and block with inter-
changeable diameter and flanging blocks, and power holder for flues or firebox
substantially as and for the purpose as herein before described.
Thirdly. The combination in a flue end flanging machine of central pillar guide
and block carreying interchangeable diameter flanging blocks and power holder,
with adjustable power rams practically at right angles to each other and mounted
on a moveable radial carriage substantially as and for the purpose as herein before
described.
Fourth. The combination of adjustable power tools practically at right angles to
each other for flanging, when the flue or fireboxes are mounted on a revolving bed
plate substantially as and for the purpose as herein before described.
Fifth. The combination of central pillar guide and revolving bed plate carreying
interchangeable diameter and flanging blocks and power holder for holding Hues
