COMPLETE SPECIFICATION.
Improvements in Wrought Tubes, Hollow Shafting, Collars, and other
such like articles, and in the Manufacture of the same.
We, JOHN SPENCER of the Globe Tube Works Wednesbury in the County of
Stafford Tube Manufacturer and SILAS DUFFIELD of Bell Street Darlaston in
the County of Stafford Stamper do hereby declare the nature of our said
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
Our invention has for its object improvements in wrought tubes hollow shafting
collars and other such like articles and in the manufacture of the same by which
we obtain a better finished and sounder tube than by the old process of manu-
facture.
In order that our invention may be clearly understood and more easily carried
into practise we have appended hereunto a double sized sheet of drawings upon
which we have illustrated the parts of a flanged tube made according to our
invention and one of the kind of set tools we use in such manufacture and from
which the application to the manufacture of other similar articles will be readily
understood.
Figure 1 represents a longitudinal section of a broken off piece of wrought
iron tubing A ready to receive a flange at the right hand end thereof.
Figure 2 represents a flange B roughly punched out or formed ready to be placed
upon the tube.
Figure 3 shows the tube A in elevation and flange B in section brought together
ready to be operated upon by the tools hereafter to be described.
Figure 4 shews an elevation of one set of our new tools with the pipe placed in
position therein ready to be operated thereon.
Figure 5 is a front elevation of the same tools but with the pipe removed so that
they may be more clearly illustrated.
Figure 6 is a modification of another set of tools in side elevation.
Figure 7 is a front view of Figure 6.
The lower tool or anvil E Figures 4 and 5 is so shaped as to have an inclination
on its face e¹ of say 45 degrees more or less and it is furnished with a mandril N
having a spigot n¹ which enters a hole in the said anvil block so as to stand square
with the inclined face thereof whatever angle the face of the block may have as
for instance as shown in the modification shewn by Figures 6 and 7. Upon this
mandril or projection the pipe A is placed as seen at Figure 4 the body being
supported between two rollers R which may either be suspended or held upon a
pillow or other suitable support. The top tool K is notched upon its face so as to
be of the exact configuration and size required for the flange and body of the
pipe when finished, for instance k¹ forms the outside face of the flange ³ forms the
hollow or angle of the back junction of the flange to the body of the tube and k* fits
the outside body of the flange. The result is that when the pipe as shown by
Figure 3 is heated to welding temperature and then placed as shown and the upper
tool K is operated either by a steam hammer stamp, press, oliver and other similar
tool the pipe being turned round after each blow or pressure thereof the flange is
beautifully welded squared up and finished with a face perfectly square to the body
of the tube and for many purposes facing such flanges in a lathe or machine is not
necessary. The same operation produces hollow flanged shafting or flanges or
collars on bars or uniting sockets to pipes but in the case of the latter the tools
may be used with very little inclination or indeed quite level in some cases.
articles are turned out by this process sound and clean and much superior to the
old mode. The manner of procedure up to Figure 3 is not new.
Such

page_text: 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 we
claim is
The improvements in wrought tubes, hollow shafting, collars and other such like
articles and in the tools used and mode of manufacturing the same substantially
as herein set forth and as illustrated upon the accompanying drawings.
