page_text: LETTERS PATENT to John Sugden, Roller Coverer, John Midgley, Music
Master, and William Clapham, Ironfounder, all of Keighley, in the
County of York, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION
OF COVERED ROLLERS USED IN MACHINERY FOR PREPARING AND SPINNING
FIBROUS MATERIALS."
Sealed the 2nd July 1861, and dated the 5th January 1861.
PROVISIONAL SPECIFICATION left by the said John Sugden, John
Midgley, and William Clapham, at the Office of the Commissioners of
Patents, with their Petition, on the 5th January 1861.
We, JOHN SUGDEN, Roller Coverer, JOHN MIDGLEY, Music Master, and
WILLIAM CLAPHAM, Ironfounder, all of Keighley, in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
CONSTRUCTION OF COVERED ROLLERS USED IN MACHINERY FOR PREPARING AND;
SPINNING FIBROUS MATERIALS," to be as follows:-
This Invention relates to an improvement or improvements on the subject
matter of certain Letters Patent granted to John Wignall Midgley, of
Keighley, for "An Improved Construction of Covered Roller to be used in
Preparing and Spinning Machinery," bearing date the 27th day of January
1858, (No. 149,) the Specification of which was duly filed, and consists of
an improvement in the method of straining the leather or other covering of

page_text: the edges of the roller, and fixing and holding the same, whereby the con-
struction of such rollers is rendered more simple, inexpensive, and effectual
than the method hitherto in use.
According to the present Invention the body of the roller consists of a disc
furnished with a central boss, through which the shaft or spindle passes, and
which boss is also tapped to receive a screw for fixing the same on the shaft.
The outer edge or periphery of the disc is furnisbed with two flanges or rims
(one at each side of the disc). projecting therefrom at right angles to the face
of the disc. The leather or other covering is stretched over the periphery of
the roller, and the edges are turned over the respective rims or flanges;
metal rings (of a smaller diameter than the interior of the flanges) are then
pressed in (one on each side), stretching the leather or other covering more
tightly, and securely holding the edges of the same between the exterior
periphery of the said rings and the interior circumference of the flanges.
The respective diameters of the rings and flanges, and the relative thickness of
the leather or other covering, are so proportioned that their mutual pressure is
quite sufficient to bind them all together, and hold them firm, without any
means of fastening whatever; but (if preferred) for greater security one or
more screws or other means of fastening may be employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Sugden, John Midgley, and William Clapham, in
the Great Seal Patent Office on the 4th July 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
SUGDEN, Roller Coverer, JOHN MIDGLEY, Music Master, and WILLIAM CLAP-
HAM, Ironfounder, all of Keighley, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of January, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said John Sugden, John Midgley, and William Clapham, Her special
licence that we, the said John Sugden, John Midgley, and William Clapham,
our executors, administrators, and assigns, or such others as we, the said
John Sugden, John Midgley, and William Clapham, our executors, adminis-
trators, 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

page_text: of Great Britain and Ireland, the Channel Islands, and Isle of Man, .an
Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF COVERED ROLLERS USED IN
MACHINERY FOR PREPARING AND SPINNING FIBROUS MATERIALS,"
upon the con-
dition (amongst others) that we, the said John Sugden, John Midgley, and
William Clapham, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Sugden, John Midgley, and
William Clapham, 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 in writing, and reference
being had to the accompanying Drawings, that is to say:-
This Invention relates to the construction of rollers covered with leather or
other material to be used in machinery for preparing and spinning fibrous
materials, and consists of an improvement in the method of constructing such
rollers for the purpose of more effectually stretching the leather or other
coverings over the surfaces thereof, and causing the edges of such coverings
to be securely held within the circular rims around the peripheries of such
rollers.
By one of the methods of covering such rollers, now in use, after the leather
or other covering material of a roller has been strained over the periphery of
the roller, and the edge thereof has been turned over the rims at the periphery
of the roller, the edges of the leather or covering material are held by rings
or plates of metal rivetted or otherwise secured to the flange of the roller.
Another method of securing the coverings of such rollers is described in the
Specification of John Wignall Midgley, (referred to in our Provisional
Specification), according to which, after the leather or other covering of a
oller has been stretched over the edges of the flanges of the roller, the edges
of the coverings are held by circular plates furnished with roughened surfaces
o hold the edges of the leather more firmly, these plates being secured by
crews.
-
According to each of these methods of construction rivets, screws, or some
ther similar means of fastening were necessary to fix the plates or other
neans employed to hold the edges of the leather, and the means employed for
olding the edges of the leather had not the effect of stretching the leather or
ther covering over the edges of the rims at the periphery of a. roller.

page_text: According to our Invention the body of the roller consists of a disc
furnished with a central boss through which the shaft or spindle passes, and
which boss is also tapped to receive a screw for fixing the roller upon its shaft.
The outer edge or periphery of the disc is formed with two flanges or rims
(one at each side of the disc) projecting therefrom at right angles to the face
of the disc. A cylindrical piece of leather, or other covering, is stretched over
the periphery of the roller in the usual way, and the edges of it are turned
over the edges of the two circular rims at the periphery of the roller, and
within those rims or flanges metal rings (of smaller external diameter than
the interiors of the flanges) but large enough to press firmly against the edges
of the covering within the rims on each side of the disc of the roller are then
introduced, one on each side, and forced within the circular rims, carrying
with them the edges of the leather or other covering towards the disc of the
roller, thus stretching the covering upon the face of the roller, and causing
the edges of it to be securely held between the exterior periphery of the rings,
and the interior surfaces of the rims. The diameters of the exteriors of the
rings and the interiors of the rims, and also the thickness of the leather or
other covering, are so proportioned to each other that. the pressure of the
rings against the edges of the covering within the circular rims, when forced
in as above mentioned, is sufficient to cause them to be held firmly in their
places, without any other means of fastening, although (if preferred), as a
further security, one or more screws or other means of fastening may be
employed in addition.
In the accompanying Drawings are Figures, showing how our said Inven-
tion may be performed or carried into practical effect, in which Figures we
have marked similar parts with the same or corresponding letters of reference.
In Figure 1 of those Drawings we have represented two covered rollers
constructed according to our Invention, one of them being shown in section, in
order more clearly to illustrate the details of the arrangement; and Figure 2
is a side view of the covered roller. a, a, is a metallic disc, provided with a
central boss b, b, whereby it is fixed on the spindle c, c, and secured by the
screw d. The disc a, a, is also furnished with a circumferential ring e, e, cast
with it and forming two circular rims or flanges, projecting at right angles,
one on each side of the disc at its periphery; f, f, is the leather or other
covering; and g, g, are rings, forced within the circular rims, so as to stretch
the covering and hold the edges of it securely. By forcing or pressing the
rings within the interiors of the two circular rims carrying with them the
edges of the covering, they will strain or stretch the leather or other covering
tightly over the outer surface of the roller, and the rings being made to fit

page_text: tightly within the circular rims and the edges of the covering, they will be
held firmly in their places, at the same time preventing the tension of the
covering from drawing out the edges of it.
If the surface of the rollers be required to be soft, a layer of felt or other
soft substance may be interposed between the covering and the metal rim, as
shewn at h, h, Figure 1, but if the rollers are to be hard or firm, the covering
material is placed upon the metallic rim.
Having now described and ascertained the nature of our said Invention,
and the manner in which it is to be performed, we declare that we do not
claim any of the mechanical elements or parts of covered rollers above
described or shown in the said Drawings apart from the combination and
application thereof in manner and for the purposes aforesaid, as being any
part of our said Invention; and that what we do claim as our said Invention
is the construction of covered rollers, having rings fitting and driven tightly
within circular rims or flanges at the peripheries of such rollers, so that
the coverings of such rollers may be stretched tightly, and the edges of such
coverings held securely, in manner herein-before described.
In witness whereof, we, the said John Sugden, John Midgley, and
William Clapham, have hereunto set our hands and seals, this Twenty-
first day of June, in the year of our Lord One thousand eight hundred
JOHN SUGDEN.
JOHN MIDGLEY.
