TO ALL TO WHOM THESE PRESENTS SHALL COME, we, DAVID.
PORTEOUS, of Whaley Bridge, in the County of Chester, Manufacturer,
and JOHN ORMEROD, of the same Place, Overlooker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of September, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said David Porteous and John Ormerod, Her
special licence that wc, the said David Porteous and John Ormerod,
our executors, administrators, and assigns, or such others as we, the
said David Porteous and John Ormerod, 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-APPARATUS. FOR
SIZING YARNS OR WARPS," upon the condition (amongst others) that we;
the said David Porteous and John Ormerod, our executors or admini-
strators, by an instrument in writing under our, or their, or one
of our or 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 David Porteous and John Ormerod,
do hereby declare the nature of our said Invention, and in what manner

page_text: the same is to be performed, to be particularly described and ascer-
tained in and by the following statement (that is to say) :-
Our Invention is applicable to the ordinary sizing machines, and it
consists in dispensing with one of the usual large wood rollers and press
rollers employed for taking the yarn or warp through the size trough,
and in applying in lieu thereof a small pressing roller to the ordinary
immersion roller. The axle of this small roller is supported in grooved.
or slotted upright guides or bars attached to the racks of the immersion
roller.
. And in order that our Invention may be fully understood and readily
carried into operation we will proceed to describe the accompanying
Sheet of Drawings, in which Fig. 1 is a section of part of an ordinary
sizing machine to which our improvements are applied, and Fig. 2 is a.
transverse section of the same.
a is the size trough, which may be made shorter than usual; b is the
ordinary immersion roller; and c, a pressing roller bearing upon it. The
axles of the immersion roller b and press roller c revolve in the slotted
uprights d, which are connected to the racks c by studs at the top.. The
racks are moved up and down in grooves in the end frames f by the
pinions and handles 9' to raise or lower the immersion roller as in
ordinary sizing machines. The press rollers h and i are similar to those
in general use, and the roller is turned round by the side shaft as
usual. The yarn to be sized is brought from the ordinary back warp
beams over the guide rollers j and k. The Drawing shews the parts in
the positions they occupy when the yarn is passing through the size
trough, that is to say, it first goes under the immersion roller 6, then
between the rollers b and c, then between the rollers h and i, and when
it leaves these rollers it is carried over the drying cylinder as usual.
When the machine is stopped the immersion roller is raised out of the
size trough by turning the handles g'.
By means of this Invention the dimensions of the size trough may be
reduced, the yarns are kept perfectly straight, or parallel to cach other,
the size is applied evenly, and hard caked or dry places are avoided, less
strain is put on the yarn owing to the absence of one pair of the pressing
rollers, thereby causing the yarn to retain its elasticity, and the wear and
tear of the machinery and the labour of the attendant are reduced.
'

page_text: Having thus stated the nature of our Invention, and described a
convenient manner of performing the same, we wish to remark that we
do not limit ourselves to the details given, as the same may be varied,
_and_that_we_claim as our improvements in apparatus for sizing yarns or
warps, the application of a press roller to the ordinary immersion roller
whereby one pair of the usual press rollers is dispensed with and less
strain is put on the yarn when being drawn through the size trough, as
described.
In witness whereof, I, the said David Porteous, for myself and on
behalf of the said John Ormerod, have hereto set my hand
and seal, this Seventh day of March, One thousand eight hundred.
and seventy-six.
