Year: 1875

page_text: LETTERS PATENT to Henry Howard & William Seddon Sutherland,
of ye Coombs Wood Tube Works, Old Hill, nr. Dudley, in ye County
of Worcester, for the Invention of "IMPROVEMENTS IN WELDING TUBES
PROVISIONAL SPECIFICATION left by the said Henry Howard and
William Seddon Sutherland at the Office of the Commissioners of
Patents, with their Petition, on the 24th June 1875.
Wė, HENRY HOWARD & WILLIAM SEDDON SUTHERLAND, of ye
Coombs Wood Tube Works, Old Hill, nr. Dudley, in ye County of
Worcester, do hereby declare the nature of the said Invention for :
"IMPROVEMENTS IN WELDING TUBES OF IRON & STEEL, & IN MEANS &
APPARATUS EMPLOYED THEREIN," to be as follows:-
These improvements relate to the method of and machinery for manu-
facturing tubes for which Letters Patent; "No. 2542 of the year 1871,
were granted to John Huggins, of Birmingham, and consist,―

page_text: First. As means for allowing more strips to be heated and welded in
any given time, the complete set of turning up, welding, and finishing
rolls are caused to move together across the furnace mouth. The strips
being laid in rotation side by side upon the furnace bottom the set of
rolls are caused to move opposite each strip as it acquires a welding
heat, and the strips pulled out of the furnace and passed through the set
of rolls. The set of rolls is then moved opposite another strip, a strip
being put into the furnace to replace the strip taken out. We prefer to
place the frame carrying the set of rolls upon slides or wheels, suitable
means of adjustment being added. The frame is caused to move by
screw gearing, rack, and pinion, or other mechanical equivalent, and the
motion made intermittent by means of friction clutch or fast and loose
pullies, or other well known means. Hydraulic power may be used.
In some cases it may be advisable to cause the straightening rolls to
move with the set of turning up, welding, and finishing rolls above
mentioned. We prefer to keep them stationary, the welded tube being
passed between them by suitable guides.
Second. As means for clearing the tube of scale and dirt whilst it is
passing through the first-mentioned set of rolls we place between any
two pairs of rolls, and preferably about the point where the scale upon
the tube has congealed, a scraper (by preference made like a pair of gas
welding tongs) of such a size as to enclose the tube tightly without
reducing it in size.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Howard and William Seddon Sutherland in
the Great Seal Patent Office on the 23rd December 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
HOWARD and WILLIAM SEDDON SUTHERLAND, of the Coombs Wood Tube
Works, Old Hill, near Dudley, in the County of Worcester, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of June, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did for Herself, Her heirs and suc-

page_text: cessors, give and grant unto us, the said Henry Howard and William
Seddon Sutherland, Her special licence that we, the said Henry Howard
and William Seddon Sutherland, our executors, administrators, and
assigns, or such others as we, the said Henry Howard and William
Seddon Sutherland, our executors, administrators, and assigns, should
at any time agree with and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for " IMPROVEMENTS IN WELDING TUBES OF IRON AND STEEL, AND IN
MEANS AND APPARATUS EMPLOYED THEREIN," upon the condition (amongst
others) that wo, the said Henry Howard and William Seddon Sutherland,
our executors or administrators; by an instrument in writing under our,
or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Henry Howard and William
Seddon Sutherland, 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, reference
being had to the accompanying Sheet of illustrative Drawings, and to
the figures and letters marked thereon, that is to say :-
These improvements relate to the method of and machinery for manu-
facturing tubes, for which Letters Patent, No. 2542 of the year 1871,
were granted to John Huggins, of Birmingham, and consist,—
First. As means for allowing more strips to be heated and welded in
any given time, the complete set of turning up, welding, and finishing
rolls are caused to move together across the furnace mouth.
The strips
being laid in rotation side by side upon the furnace bottom the set of
rolls are caused to move opposite each strip as it acquires a welding
heat, and the strip pulled out of the furnace and passed through the set
of rolls. The set of rolls is then moved opposite another strip, a strip
being put into the furnace to replace the strip taken out. We prefer to
place the frame carrying the set of rolls upon slides or wheels, suitable
means of adjustment being added. The frame is caused to move by

page_text: screw gearing, rack and pinion, or other mechanical equivalent, and the
motion made intermittent by means of friction clutch or fast and loose
1.,pullies or other well known means. Hydraulic power may be used. In
some cases it may be advisable to cause the straightening rolls to move
with the set of turning up, welding, and finishing rolls above mentioned.
We prefer to keep them stationary, the welded tube being passed between
them by suitable guides.

Second. As means for clearing the tube of scale or dirt whilst it is
passing through the first-mentioned set of rolls we place between any
two pairs of rolls and preferably about the point where the scale upon
the tube has congealed a scraper (by preference made like a pair of gas
**welding tongs) of such a size as to enclose the tube tightly without
reducing it in size.
1-
Fig. 1 is a side clevation, and Fig. 2 a plan · view✨ illustrative of our
Invention. a, framework containing turning up rolls b, welding rolls c,
and finishing rolls d. The said rolls are caused to rotate by the gear e.
f, screw driven by the gear g; h, fast pulley; i, loose pullies; j, driving
bands, the one crossed, the other straight. It will be evident that by
changing the position of the bands the apparatus can be caused to
traverse on the rails and slide by the rotation of the screw f so as to
pass in front of the furnace m from one side to the other. n, metal
strips to be formed into tubes; these strips are each taken up and passed
_ in turn between the rolls b, c, d, as the apparatus comes opposite to each
of the said strips.
די
'
It will be evident that as the said strips are passed through the rolls
one; after the other no time is lost in waiting for the metal to be heated.
It will also be obvious that the furnace might be caused to move, and
the welding apparatus remain stationary.
"
The second part of our Invention is illustrated by the scrapers p on
Fig. 2. The said scrapers clean off any scale on the tubes before passing
through the finishing rolls d.
It will be evident that various arrangements of parts may be used in
carrying out our Invention, such as using hydraulic power to give tra-
versing motion to the welding apparatus.

page_text: Having now described the nature of our said Invention, so that others
will be enabled to practice the same, we claim,-
First. The improvements substantially as set forth under the first
head.
Second. Arranging apparatus to operate in conjunction with a
heating furnace for forming or welding tubes, substantially as herein.
set forth.
Third. The use of the scrapers p in a tube forming or welding machine,
substantially as and for the purposes set forth.
In witness whereof, I, the said William Seddon Sutherland, have
hereunto set my hand and seal, the Twenty-first day of December,
in the year of our Lord One thousand eight hundred and seventy-.
five.
