AND TUBES."
PROVISIONAL SPECIFICATION left by the said George Walter Dyson
and Henry Arthur Hall at the Office of the Commissioners of
Patents, with their Petition, on the 31st October 1870.
We, GEORGE WALTER DYSON and HENRY ARTHUR HALL, of the
Carbrook Forge and Rolling Mills, Tinsley, near Rotherham, in the
County of York, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN ROLLING AND FINISHING CIRCULAR METAL PLAIN OR
IRREGULAR RODS AND TUBES," to be as follows:-
Our Invention consists in rolling metal rods and tubes between two
rolling solid or hollow bodies, such as discs or lumps on the ends of the
shafts or axles. The rod or tube is guided between the discs by suitable

page_text: guide bars or other appliances, and the guides are capable of being
raised and lowered to determine the forward or backward action of the
rod or tube under operation. The rod or tube may, be made parallel or
with an irregular or tapered exterior surface as desired.
SPECIFICATION in pursuance of the conditions of the Letters 'Patent,
filed by the said George Walter Dyson and Henry Arthur Hall
in the Great Seal Patent Office on the 29th April 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
WALTER DYSON and HENRY ARTHUR HALL, of the Carbrook Forge and
Rolling Mills, Tinsley, near Rotherham, in the County of York, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirty-first day of October, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors;
give and grant unto us, the said George Walter Dyson and Henry
Arthur Hall, Her special licence, that we, the said George Walter
Dyson and Henry Arthur Hall, our executors, administrators, and
assigns, or such others as we, the said George Walter Dyson and
Henry Arthur Hall, 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 ROLLING AND FINISHING CIRCULAR METAL
PLAIN OR IRREGULAR RODS AND TUBES," upon the condition (amongst others)
that we, the said George Walter Dyson and Henry Arthur Hall, or one
of us, our executors or administrators, by an instrument in writing under
our, or one of 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 George Walter Dyson and Henry
Arthur Hall, do hereby declare the nature of our said Invention, and

page_text: in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement thereof, reference
being had to the Drawings hereunto annexed, that is to say :-
Our Invention consists in rolling and finishing metal rods and tubes
between two rolling solid or hollow bodies, such as discs or lumps on
the ends of shafts or axles, the rod or tube is guided between the discs
by suitable guide bars or other appliances, and the guides are capable of
being raised and lowered to determine the forward or backward action of
the rod or tube under operation. The rod or tube may be made parallel
or with an irregular or tapered exterior surface as desired.
The accompanying Drawings represent how we carry our Invention
into effect.
Figure 1 is a view of the ends of two shafts A and B with lumps or
discs C, D, thereon; these discs are chamfered or inclined on their faces
to form flat surfaces for acting upon the bar or rod E, which is placed
between them to be reduced or rolled. The shafts are held in housings,
and driven in the ordinary manner by gearing or by friction.
In the Figure we have shown the shafts as being set at an angle to one
another so that the bar or rod is acted upon by the opposite sides of the
discs, but this is not essential in all cases, as the shafts may be set in
the housings in different lines, such as one above or at the side of the
other, that is to say, one of them would be fitted so that the opposite
face of each disc would form a rolling surface for the rod or bar, as
shewn in Figures 3 and 4, and then the rod or bar would be acted upon
by the outer faces of each disc. The rotation of the shafts would be
such that as the rod or bar is acted upon it would travel through
between the discs, and thus cause fresh portions to be rolled or reduced,
the feeding being governed by the position of the rod or bar; if the rod
or bar is required to go in one direction it is pressed a little below the
centre line of the disc, if in the opposite it is passed over the centre
line. The discs may however be caused to rotate so as only to reduce
and not to feed, and in that case the rod or bar would be held in the
centre line of the disc when it would only rotate and not move in an end
direction.
The rod or bar is prevented canting during the rolling by suitable
guides, as seen at F, or it may be made to pass through the mouths of
tubes arranged at the ends for the purpose, or between rollers, which
may be feed rollers or not.

page_text: We have referred more particularly to rods or bars, but tubes can be
'acted upon
in the same manner, whether for rolling or finishing them,
as before spoken of, if the tubes are being reduced in a hot state, a
mandril in the inside would be employed to preserve the rotundity on
the interior, which mandril can be withdrawn at will by passing through
the disc, this enlarges the interior and thereby loosens the mandril.
In some cases the working faces of the discs are not parallel, so that
articles of a tapered form can be reduced or finished; and to enable this
to be done we arrange the guides in a rising and falling frame, so as to
lift or depress the article for a narrower or a broader portion of the faces
to act upon them; or in lieu of that the shafts can be moved end on
towards one another, or the centres may be made to approach one
another as desired.
There is no limit to the dimensions of the discs, as those can be suited
to the sizes of the articles to be produced or finished, and discs of
different sizes can be used as pairs, and these may travel at the same or
at different speeds.
And having now described the nature of our said Invention and in
what manner the same is to be performed, we declare that we claim,―
Firstly. Rolling or finishing circular metal plain or irregular rods and
tubes, substantially in the manner described and shewn.
Secondly. The employment of discs or lumps on the ends of the shafts
or axles for rolling and finishing circular metal rods and tubes, as herein-
before described and shown in the Drawings.
In witness whereof, I, the said George Walter Dyson and :
Henry Arthur Hall, have hereunto set our hands and seals, this
Twenty-eighth day of April, One thousand eight hundred and
seventy-one.

HENRY ARTHUR HALL.

WHEREAS Her Majesty Queen Victoria by Her Royal Letters Patent,
bearing date the Thirty-first day of October One thousand eight hundred
and seventy, did grant unto the above-named George Walter Dyson
and Henry Arthur Hall, our executors, administrators, and assigns, the.
sole privilege to make, use, exercise, and vend the said Invention of
"IMPROVEMENTS IN ROLLING AND FINISHING CIRCULAR METAL, PLAIN AND IRREGU-
LAR RODS AND TUBES," within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and the Isle of Man, during the term of
fourteen years then next ensuing.
And whereas, we, the said George, Walter Dyson and Henry Arthur
Hall on the Twenty-eighth day of April One thousand eight hundred
and seventy-one, within the time prescribed by the said Letters Patent,
caused a Specification in writing, under our hands and seals, to be filed
in the Great Seal Patent Office.
And whereas after the date of the application for the said Letters
Patent, and since the filing of the Specification in pursuance thereof,
we have ascertained and been advised that the description of the said
Invention is too broad, and contains matter which was not new and
original at the date of the said application for Letters Patent, particularly
the matter described with reference to placing the shafts at an angle to
each other, and shown at Figure 1 of the Drawings annexed to the said
Specification.
And in order to render the said Specification more definite, clear, and
distinct, we propose to make the several alterations, erasures, and correc-
tions therein as herein-after contained.
NOW KNOW YE, therefore, that we, the said George Walter Dyson
and Henry Arthur Hall, by and with the leave of Her Majesty's
Solicitor General, do hereby for the reasons aforesaid, and in order to
more clearly define and limit the true nature of our said Invention and
the manner of carrying it into practical effect, make the following
alterations and erasures in the said Specification, that is to say :-
"
.We insert the letter "s "after the word "Figure" at line 13, page 3,
of the said Specification, and we insert the words and numeral "and 2
in place of "is a," and we insert the letter "s" between the words
"view of," so that the line would read thus,-" Figures 1 and 2 are
views of."
