page_text: LETTERS PATENT to Frederick Walton, of Haughton Dale Mills, near
the City of Manchester, Card Manufacturer, for the Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF ROLLERS USED IN MACHINERY FOR
PREPARING AND SPINNING FIBROUS MATERIALS, AND FOR OTHER PURPOSES
WHERE ELASTIC PRESSURE IS REQUIRED; ALSO IN THE MACHINERY EMPLOYED IN
THE MANUFACTURE OF THE SAID ROLLERS."
Sealed the 4th June 1858, and dated the 12th December 1857.
PROVISIONAL SPECIFICATION left by the said Frederick Walton at
the Office of the Commissioners of Patents, with his Petition, on the
12th December 1857.
I, FREDERICK WALTON, of Haughton Dale Mills, near the City of Man-
chester, Card Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OP ROLLERS USED IN MACHINERY FOR
PREPARING AND SPINNING FIBROUS MATERIALS, AND FOR OTHER PURPOSES WHERE
ELASTIC PRESSURE IS REQUIRED; ALSO IN THE MACHINERY EMPLOYED IN THE
MANUFACTURE OF THE SAID ROLLERS," to be as follows:-
The nature of my Invention consists in manufacturing rollers suitable for
the top rollers of drawing rollers used in preparing and spinning fibrous
materials, by covering a metal spindle or axis with vulcanized india-rubber
or other suitable elastic material (put on either solid or in rings or washers),
and in covering the elastic material either with a thin metal tube, or winding
a coil of iron or other wire over the elastic material. When a coil of wire

page_text: is employed, the ends thereof must be secured by soldering or otherwise, and
the surface of the wire may be filed smooth in the lathe, or a coating of
varnish may be made on the roller to make a smooth surface. Theso
improvements are also applicable to rollers of larger dimensions for squeezing
or compressing other articles requiring elastic pressure. The body of the
roller may be of wood or other material.
My improvements in machinery consist in the application of a guide spindle,
to assist in coiling the wire at a uniform tension on tho elastic material forming
part of the improved roller. After the axis or spindle has been covered with
the elastic material it is placed in a frame, supporting also the guide spindle,
which has wire coiled around it similar to that with which the roller is to be
covered. The guide spindle and the roller are connected by gearing. A
pointer fits in the groove of the wire on the guide spindle, and this pointer
is made with an instrument which lays the wire evenly on the roller
to be covered. The wire in passing to the roller to be covered passes
under a weighted finger, by which means a uniform tension is obtained.
The machinery for coiling the wire on to the roller may be considerably
modified.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Walton in the Great Seal Patent Office on the
19th June 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
WALTON, of Haughton Dale Mills, near the City of Manchester, Card Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of December, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Frederick Walton, Her special licence that I, the said Frederick Walton,
my executors, administrators, and assigns, or such others as I, the said
Frederick Walton, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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
THE MANUFACTURE OP ROLLERS USED IN MACHINERY POR PREPARING AND SPINNING

page_text: FIBROUS MATERIALS, AND FOR OTHER PURPOSES WHERE ELASTIC PRESSURE IS
REQUIRED; ALSO IN THE MACHINERY REQUIRED IN THE MANUFACTURE OF THE SAID
ROLLERS," upon the condition (amongst others) that I, the said Frederick
Walton, my executors or administrators, by an instrument in writing under
my, 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 I, the said Frederick Walton, 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 (that is to say):-
The nature of my said Invention consists in manufacturing rollers suitable
for the top rollers of drawing rollers used in preparing and spinning fibrous
materials, and for other purposes where elastic pressure is required, by covering
a metal or other spindle or axis with vulcanized india-rubber or other suitable
elastic material, and in covering the elastic material either with a thin metal
tube or winding a coil of sheet metal or wire over the elastic material.
When a coil of wire is employed, the ends thereof must be secured by
soldering or otherwise, and the surface of the wire may be filed smooth in
the lathe, or a coating of varnish may be laid thereon to make a smooth
surface.
My improvements in machinery employed in the manufacture of the said
rollers consists in the application of a pointer to a roller or guide spindle,
around which wire is coiled, which pointer and guide spindle assist in coiling
the wire on the elastic material forming part of the improved roller; the wire
is kept at a uniform tension by a weighted finger.
And in order that my Invention may be fully understood and readily carried
into operation, I will proceed to describe the means pursued by me, reference
being had to the accompanying Sheet of Drawings, and to the figures and
letters marked thereon.
Fig. 1 represents a top roller suitable for the drawing rollers of a machine for
spinning cotton; the axis or spindle of the top roller is covered with vulcanized
india rubber or other suitable elastic material, put on either solid or in rings
or washers, and this elastic material is covered either with a thin metal tube,
as shewn at the left-hand boss, or with a band of sheet metal, as shewn at the
right-hand boss. When a thin metal tube is used to cover the elastic material,
I prefer to make the joint in a diagonal direction, as the soldering or brazing

page_text: of the joint is then less liable to be broken than when the joint is in a lino
with the axis. When the elastic material is covered with a band of sheet
metal the ends thereof may be soldered; it is sometimes desirable to use two
.bands of sheet metal with the joints crossing, as shown by the dotted lines in
Fig. 1. By thus manufacturing top rollers a considerable amount of clasticity
and great durability are obtained.
Fig. 2 represents a top roller constructed according to a modification of my
Invention; in this instance the elastic material is covered over with a coil of
iron or other wire; when the wire is put on, the ends thereof must be soldered
or otherwise secured to prevent it unwinding, and in order to obtain a smooth
surface on the circumference of the roller the surface of the wire is filed
smooth, as shown to the left-hand side of Fig. 2; or, the wire is coated with
varnish, as shewn at the right hand of Fig. 2.
Fig. 3 represents a top roller constructed according to another modification
of my Invention. The elastic material is contained between shoulders on the
spindle, and the sheet metal tube is soldered to the said shoulders; the boss
of the top roller must be rather longer than the fluted portion of the bottom
roller, as shown in the Drawing, in order that the requisite elasticity may bo
obtained between the two; rollers of largo dimensions may be constructed as
above described for squeezing or compressing fabrics or other articles requiring
elastic pressure.
Fig. 4 is a plan, and Fig. 5 an end elevation of a machine employed in the
manufacture of the rollers shewn in Fig. 2. a is a roller or guide spindle,
around which wire is coiled, the wire being of the same size as that required
to be coiled over the elastic material on the top roller b; the roller or guido
spindle a and the top roller b are connected by gearing, shewn by dotted
circles in Fig. 5, so that they may both revolve at the same speed. The guide
bar c supports the guide d and pointer e, which fits between the spaces of the
wire on the guide spindle a, consequently as the said spindle revolves it causes
the pointer and guide to traverse, and in so doing lays the wire which passes
through an eye of the guide d on to the elastic material of the top roller. The
wire in passing to the roller to be covered is pressed upon by the weighted
finger f, by which means a uniform tension is obtained. This machinery for
laying the wire may be considerably modified.
Baving thus stated the nature of my Invention, and described the manner
of performing the same, I declare that I claim,-
First, the combination of wire or sheet metal with vulcanized india-rubber
or other suitable elastic material in the manufacture of rollers, as described, or
any modification thereof.

page_text: And, secondly, the machinery shewn and described in reference to Figs. 4
and 5, for coiling wire around top rollers.
In witness whereof, I, the said Frederick Walton, have hereunto set my
hand and seal, this Tenth day of June, in the year of our Lord One
thousand eight hundred and fifty-eight.
