IMPROVE- MENTS IN MACHINERY OR APPARATUS FOR SIZING Warps
Year: 1858

page_text: LETTERS PATENT to Thomas Leigh, of the City of Manchester, in the
County of Lancaster, Commission Agent, for the Invention of "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR SIZING Warps."
Sealed the 19th October 1858, and dated the 16th July 1858.
PROVISIONAL SPECIFICATION left by the said Thomas Leigh at the
Office of the Commissioners of Patents, with his Petition, on the
16th July 1858.
I, THOMAS LEIGH, of the City of Manchester, in the County of Lancaster,
5 Commission Agent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SIZING WARPS," to be as
follows:-
I apply a steam apparatus, commonly called a steam chest, to the ordinary
sizing machine, generally known by the name of "tape leg," instead of the
O drying cylinders as used in the said machines. By the use of the steam chest

page_text: I avoid contact of the yarn with the surface of the drying apparatus, by causing
it to interweave through a number of rollers, either vertically or horizontally,
within the steam chest, without coming in contact with the steam pipes or
cylinders.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Leigh in the Great Seal Patent Office on the
15th January 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
LEIGH, of the City of Manchester, in the County of Lancaster, Commission
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of July, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-second year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Thomas Leigh, Her special licence that I, the said Thomas Leigh, my
executors, administrators, and assigns, or such others as I, the said
Thomas Leigh, 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 OR APPARATUS FOR SIZING WARPS," upon the condition (amongst
others) that I, the said Thomas Leigh 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 months next and immediately after the date of the said Letters
NOW KNOW YE, that I, the said Thomas Leigh, 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) :-
My said Invention consists of applying to the ordinary sizing machines or
tape legs one or more steam chests or boxes for the purpose of drying the

page_text: warps, instead of the ordinary drying cylinders as hitherto adopted, which
improved arrangement is peculiarly adapted for drying warps that have passed
through silicate size, as patented by John Leigh, the Seventh day of April,
One thousand eight hundred and fifty-six, No. 838, the said silicate size being
used instead of flour, starch, or similar sizing materials. The steam chests
may be arranged in a series, and constructed of various forms, and placed
either in a vertical, horizontal, or angular position, and are also furnished with
guide rollers in order to guide the warps near the surface of the chests
without coming in contact with them, thereby preventing any adhesion.
The manner in which my said Iuvention is to be performed will be clearly
understood by reference to the accompanying Sheet of Drawings, and the
letters of reference thereon, in which Fig. 1 is a side elevation of the
principal part of a sizing machine, furnished with my improved steam chests,
and Fig. 2 a plan of the same. The steam chests or boxes are represented
at a, supported by the frames b, which are fixed at one end-to the.size trough c
and at the other to the ordinary framing d. The warps from the creel are
shewn at e, passing through the size trough and under the pressing rollers in
the usual manner. From the last pressing roller f the warps pass under the
guide roller g to the first of the guide rollers h, and from thence to the first of
the bottom guide rollers i, from whence theypass over and under the other guide
rollers h and i, according to the number of the series of steam chests. From
the last of the rollers i, the warps pass over the roller k, and onward to the
yarn beam 7, as in the ordinary machines. The guide rollers are of such
diameters as to allow the warps as they pass through the machine to be near
the chests, and thereby become dried by the radiation of the heat; or if
cylinders are used they may be rodded with wood or other suitable material, to
prevent the contact of the warps with the metal, and the consequent adhesion.
The system of stationary steam chests enables me to obtain a great encrease of
heating surface, and by 'employing a larger size trough and a greater number
of pressing rollers, the machine can be worked at a much higher speed than
usual, and thus produce more work in a given time.
Having thus fully described the nature 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 the precise details hercin set forth,
as such may be varied or modified without departing from the principle thereof,
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 application to

and seal, this Thirteenth day of January, in the year of our Lord One
thousand eight hundred and fifty-nine.
Signed, sealed, and delivered by the within-
named Thomas Leigh, in the presence of,
E. J. HUGHES, Patent Agent,
Manchester.
THOMAS LEIGH. (L.S:)
