page_text: LETTERS PATENT to William Smith Longridge, of Alderwasley İron
Works, Ambergate, in the County of Derby, Engineer, for the Inven-
tion of "IMPROVEMENTS IN MACHINERY FOR ROLLING TYRES, HOOPS, AND
RINGS."
Sealed the 9th June 1863, and dated the 19th December 1862.
PROVISIONAL SPECIFICATION left by the said William Smith Longridge
at the Office of the Commissioners of Patents, with his Petition, on
the 19th December 1862.
.I, WILLIAM SMITH LONGRIDGE, of Alderwasley Iron Works, Ambergate, in
the County of Derby, Engineer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR ROLLING TYRES, HOOPS, AND
RINGS," to be as follows:-
My improvements in the manufacture of tyres of railway and other wheels,
and of sheets or plates for boilers and other purposes, refers to rollers or
rolling machinery employed in such manufacture, by which I am enabled to
roll such tyres, or sheets, or plates in the form of hoops or rings. The upper
rolls of my improved machinery I mount in the manner usual in rolling
machinery. The lower, rolls I mount in such manner that when the tyres,
hoops, or rings are passed into or removed from the machines, they are passed

page_text: between the ends of the lower rolls and the side frames of the machines which
carry the bearings of the rolls. Thus, in describing one machine, one end of
the lower roll does not reach into or up to the side frame or standard of the
machine at one end of it (the roll), but an intermediate or open space is left
between the end of the roll and the frame or standard sufficient to allow the
bloom for the tyre, hoop, or ring to be passed between them, and inserted
between the rolls and removed therefrom when finished. The bearing which
carries the end of the roll is mounted upon a carriage sliding longitudinally
into or upon the side framing of the machine in such manner that when it is
traversed backwards from the roll, the intermediate or open space referred to
between the roll and the framing, is left free for the passage of the bloom for
the tyre, hoop, or ring, which is to be or has been operated upon by the rolls,
as the case may be, and when it is traversed in the opposite direction, or that
towards the roll, it projects inwards between the frames, and receives the
journal or end of the roll forming its bearing and support. When a tyre,
hoop, or ring is to be rolled or operated upon the bearing carriage is traversed
back, so as to leave the intermediate or open space for the insertion of the
tyre, hoop, or ring free. The tyre, hoop, or ring is then passed in and placed
between the rolls, the bearing carriage is then traversed forward until it takes
the journal or end of the roll, when the tyre, hoop, or ring may then be rolled
in the manner usual with rolling machinery. Upon completion of the rolling
operation the bearing carriage is again traversed, and the tyre, hoop, or ring
removed from the machine. When hoops or rings are required to be of
widths greater than the internal space referred to between the end of the roll
and the framing, I then construct the machine so that the lower roll may be
traversed longitudinally from between the frames to any extent requisite to
allow the passing of the hoops or rings to and from the machine. The
traverse of the bearing carriage and of the roller I effect by hydraulic or any
other convenient or suitable means.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed 8
by the said William Smith Longridge in the Great Seal Patent Office
on the 15th June 1863.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
SMITH LONGRIDGE, of Alderwasley Iron Works, Ambergate, in the County of
Derby, Engineer, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth December, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Smith Longridge, Her special license, that I, the said
William Smith Longridge, my executors, administrators, and assigns, or such
others as I, the said William Smith Longridge, my 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 MACHINERY FOR ROLLING TYRES,
HOOPS, AND RINGS," upon the condition, amongst others, that I, the said
William Smith Longridge, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said Inven-
tion, 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 I, the said William Smith Longridge, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings (that is to say):-
My improvements in the manufacture of tyres of railway and other wheels,
and of sheets or plates for boilers, and for other purposes, refer to rollers or
rolling machinery employed in such manufacture, by which I am enabled to
roll such tyres, or sheets, or plates, or other sections of metal in the form of
hoops or rings. The upper roll of my improved machinery I'mount in the
manner usual in rolling machinery, and the lower roll I mount in such manner
that when the tyres, hoops, or rings are passed into or removed from the
machines they are passed between the end of the lower roll and the side frame
which carries the bearing of the roll.
Thus, in describing my improvements in reference to one machine, and
referring to the Drawings hereunto annexed, which represent so much of a
machine as is sufficient to illustrate my improvements; one end A' of the
lower roll A when in its working position, as shown, does not reach into or up
to the side frame or standard B of the machine, but an intermediate or open
space
is left between the end of the roll and the side frame or standard suffi:
cient to allow the bloom for the tyre, hoop, or ring to be passed between them,

page_text: and inserted between the upper and the lower rolls and to be removed there-
from. The bearing C which carries this end of the lower roll is mounted
upon a carriage D sliding longitudinally into or upon the frame B to and from
the lower roll A, so that when it is traversed backwards from the roll the
intermediate or open space referred to between the roll and the frame is left
free for the passage of the bloom, tyre, hoop, or ring into or from, between the
rolls, as required, and when the bearing carriage is traversed in the opposite
direction, or towards the lower roll it projects inwards between the frames
and receives the journal or end A² of the lower roll, thus forming its bearing
and support, and upon which it revolves; E is an hydraulic cylinder, secured
to the foundation framing of the machine for the purpose of traversing the
bearing carriage D. Any other means may be used for the purpose of tra-
versing the bearing carriage instead of the hydraulic cylinder, as convenient.
When a tyre, hoop, or ring is to be rolled or operated upon in the machine
the action is thus:-The upper roll is raised, the bearing carriage is then
traversed back from the lower roll, so as to leave the intermediate spacó
between the end of the roll and the frame open and free for the passage of
the bloom or tyre into or between the rolls, the bloom or tyre is then intro
duced, the bearing carriage is then traversed back to the roll; the upper
roll is then brought down, and the rolling proceeds in the usual manner of
such operations. This being finished the upper roll is again raised sufficiently,
the bearing carriage is traversed back, and the tyre, hoop, or ring. removed
from the machine. When hoops or rings of greater width than the interval
of space between the end of the lower roll and the frame above referred to
are required, I then construct the machine so that the lower roll itself is
traversed longitudinally to any extent requisite to allow the passing of the
hoops or rings into and from between the rolls. The end A" of the lower roll
is supported by the bearings E, F, upon the sliding carriage G, which is
traversed by the hydraulic cylinder H, thus the lower roll is traversed, as
required, for the introduction and the withdrawal of the article under opera-
tion in the machine.
I claim as my Invention of improvements in machinery for rolling tyres,
hoops, or rings,
First, the withdrawal and the replacement of one of the bearings of the
lower roll of such machinery for the purpose of the introduction into and the
removal from between the rolls of the blooms, tyres, hoops, or rings of what-
ever section under operation.
Second, the withdrawal and the replacement of the lower roll of such

page_text: machinery for the purpose of the introduction into and the removal from
between the rolls of the blooms, tyres, hoops, or rings of whatever section
under operation.
Third, the use and application of my improvements referred to in first and
second claims separately or in combination in one machine.
In witness whereof, I, the said William Smith Longridge, have hereunto
set my hand and seal, this Eighth day of June, in the year of our Lord
One thousand eight hundred and sixty-three.
WILLIAM S. LONGRIDGE. (LS.)
