page_text: LETTERS PATENT to Charles Renshaw, of Dukinfield, in the County of
Chester, Engineer and Millwright, for the Invention of "IMPROVEMENTS
IN SQUEEZING ROLLERS, APPLICABLE TO MACHINERY OR APPARATUS FOR PRESS-
ING OR PARTIALLY DRYING YARNS AND WOVEN FABRICS."
Sealed the 27th January 1857, and dated the 26th September 1856.
PROVISIONAL SPECIFICATION left by the said Charles Renshaw at the
Office of the Commissioners of Patents, with his Petition, on the
26th September 1856.
1.
I, CHARLES RENSHAW, of .Dukinfield, in the County of Chester, Engineer
and Millwright, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN SQUEEZING ROLLERS, APPLICABLE TO MACHINERY OR APPARATUS
FOR PRESSING OR PARTIALLY DRYING YARNS AND WOVEN FABRICS," to be as
follows:-
Instead of using the ordinary rollers, composed of metal, wood, or other hard
substances, through or between which the damp goods pass to be squeezed or
pressed in contact with the hard surface, I propose to cover the said rollers
with caoutchouc or some similar elastic substance, which will have the property
of yielding or giving way to the different or various substances that may pass
through or between them, and which will have the effect of more effectually

page_text: squeezing or pressing all the parts or portions of the material, however uneven
or different in substance the parts or portions of the material may be. And
for the purpose of more effectually squeezing all the parts of yarn in the bank
or warp, or similar materials which are much thicker in substance in the
centre than at the edges, I make the flexible substance much stronger in the
contre than at the edges, as will be clearly understood by reference to
the accompanying outline Drawing, in which Fig. 1 represents a front eleva-
tion of the roller, shewing the flexible material at the dotted lines, which
encreases in thickness from the edge to the centre; and Fig. 2 is a plan of
the same.
This difference of substance in the flexible material will not be found
generally necessary in squeezing woven fabrics, unless the woven fabric is in
a twisted form when passing through the machine..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Renshaw in the Great Seal Patent Office on the
25th March 1857
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
RENSHAW, of Dukinfield, in the County of Chester, Engineer and Millwright,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Royal
Letters Patent, bearing date the Twenty-sixth day of September, in the year of
our Lord One thousand, eight hundred and fifty-six, in the twentieth year of
Her reign, did, for Herself, Her heirs and successors,. give and grant unto me,
the said Charles Renshaw, Her special licence that I, the said Charles Renshaw,
my executors, administrators, and assigns, or such others as I, the said Charles
Renshaw, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at afl 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
SQUEEZING ROLLERS, APPLICABLE TO MACHINERY OR APPARATUS FOR PRESSING OR
PARTIALLY DRYING YARNS AND WOVEN FABRICS," upon the condition (amongst
others) that I, the said Charles Renshaw, by an instrument in writing under
my hand and seal, 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

page_text: months next and immediately after the date of the said Royal Letters
Patent.
NOW KNOW YE, that I, the said Charles Renshaw, do hereby declare the
nature of the 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):
My Invention consists in covering the squeezing rollers with caoutchouc or
some similar elastic substance, instead of using the ordinary rollers, composed
of metal, wood, or other hard substances, through or between which the damp
goods pass to be squeezed or pressed. The covering of the said rollers with
elastic material will give them the property of yielding or giving way to the
different or various substances that may pass through or between them, and
which will have the effect of more effectually squeezing or pressing all the
parts or portions of the material, however uneven or different in substance the
parts or portions of the material may be. And for the purpose of more
effectually squeezing or pressing all the parts of yarn in the bank or warp, or
similar materials which are much thicker in substance in the centre than, at
the edges, I make the flexible substance which covers the rollers much stronger
in the centre than at the edges. This difference of substance in the flexible
material will not be found generally necessary in woven fabrics, unless they
are in a twisted form when passing through the machine. In order more
effectually to place the flexible material on the roller, I divide the latter into
two parts, holding them firmly together by a key through the shaft.
.
These improvements will be clearly understood by reference to the accom-
panying two Sheets of Drawings, with the figures and letters of reference
thereon. The Figure (on Sheet 1) is a front elevation of a squeezing machine
having my improved covered rollers, one of which is shewn section. The
Figure (on Sheet 2) is a transverse elevation of the machine on Sheet 1. In
both Figures, a represents the flexible covering placed over the roller, com-
posed of two parts b and c, which are placed upon the shaft d, and held firmly
by the key c.
Having thus fully described the nature and particulars of my said Invention,
and the manner in which the same is to be performed, I desire it to be
distinctly understood that I do not confine myself to any particular description
of elastic material (though caoutchouc may be the best for the purpose), nor
to any particular thickness or dimensions of the same; but I claim as my
Invention, and which, to the best of my knowledge and belief, has not been
hitherto used within the realm, the use of any elastic material thicker or
stronger in the centre than at the edges, for covering squeezing rollers, the

page_text: said squeezing rollers being made in two parts for the purpose of more easily
fixing on the elastic material, and the application of the same to squeezing
or pressing yarns or woven fabrics..
In witness whereof, I, the said Charles Renshaw, have hereunto set my
-
hand and seal, this Twenty-fourth day of March, in, the year of our
Lord One thousand eight hundred and fifty-seven.
