COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Flanging Land
and Marine Boiler Flues upon the 66 Adamson" Principle.
WO GEORGE BOOTH and GEORGE PICKERSGILL, Engineers and Tool Makers both of
the firm of Messieurs George Booth & Co. of Central Iron Works Halifax in the
County of York, 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 :—
DESCRIPTION OF DRAWINGS.
Fig. 1. is a side elevation of a vertical flanging machine with our improvements
applied.
Fig. 2. is a front elevation of Fig. 1.
Fig. 3. is a plan of Fig. 1.
A. is the vertical frame upon which is the horizontal slide B carried by the vertical
saddle M, upon which are the horizontal saddles C, which have cast thereto solid
arms D and E these arms carry the guide rollers F and G, adjustable upon the slides
by means of right or left hand screws H.
The saddles are carried by the vertical saddle M, upon the vertical slide N ; J is
the plate bending roller, and J¹ is a roller upon which the plate is bent, the roller J is
carried by stud K on an arm pivotted on shaft L to saddle M upon the vertical slide N
of the frame A.
The shaft carries a wheel or segment O, gearing with a worm P on shaft R operated
by bevel wheels R' and R2 from vertical shaft. R having bevel wheels R, R³, and R,
operated from a separate driving shaft R7, and put in and out of gear by clutch
mechanism, friction or other suitable gear.
The saddle M. is balanced by chain S, passing over the guide pulley S¹ and
weight S2.
T is the ordinary revolving table, operated by gear wheel
wheels T and T4, shaft T and fast and loose pulleys T
baving adjustable grips V to hold the boiler flue or tube in
flanged.
T¹, pinion T2, bevel
and T7; the table
position, whilst being
W is the bed of the machine having adjustable saddle X and slide Y; Z is the
adjusting screw. The dotted lines showing large and small sizes of boiler flues or
tubes being flanged.
The action is as follows:-
Upon the machine being set in motion, the table revolves with the boiler flue or
tube, the guide rollers F and G being set up to the outside of the boiler flue or tube
to steady it and keep it firm, the bending roller which has been raised by the worm P,
and segment O, is brought down upon the inside of the boiler flue or tube and turns it
over upon the roller J'; the distance between the bottom of the bending roller J, and
the roller J, is the thickness of the plate of the boiler flue or tube being flanged, this
distance is regulated by putting a thicker or thinner ring or washer J³ below the roller J¹
or by changing thickness of roller or other equivalent.
The vertical saddle M is raised or lowered by vertical shaft M¹ operated by bevel
wheels M and M³, cross shaft M* and hand wheel M³. The vertical shaft R has a
tey way T, so that the bevel wheel R* may slide upon the shaft as the saddle M is
aised or lowered.
This arrangement of apparatus will flange either parallel or taper tubes, of various
izes and thicknesses

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :-
1. In vertical flanging machines, operating the plate bending roller by power for
the purposes shown and described.
2. In vertical flanging machines operating the plate bending roller by wheel or
segment, operated by worm or other gear from the top of the machine by power such
as shown and described.
3. The combination of the pivotted flanging roller J, wheel or segment U. worm P,
cross shaft R, vertical shaft R³, with bevel wheels R', R2, R4, R and R or other
equivalents, operated by clutch, friction or other gearing, such as shown and
described.
4. In vertical flanging machines, casting the arms D, and E, carrying guide
rollers F and G, in one piece upon the saddle C, such as shown and described.
