Year: 1874

page_text: LETTERS PATENT to Edward Lord, of Todmorden, in the County of
York, Machine Maker, for the Invention of "IMPROVEMENTS IN SIZING
MACHINES AND IN APPARATUS FOR DRYING YARN IN THE PROCESSES OF SIZING,
DRESSING, BLEACHING, AND DYEING."
Sealed the 17th March 1874, and dated the 10th January 1874.
PROVISIONAL SPECIFICATION left by the said Edward Lord at the
Office of the Commissioners of Patents, with his Petition, on the
10th January 1874.
I, EDWARD LORD, of. Todmorden, in the County of York, Machine
Maker, do hereby declare the nature of the said Invention for "Iμ-
PROVEMENTS IN SIZING MACHINES AND IN APPARATUS FOR DRYING YARN IN THE
PROCESSES OF SIZING, DRESSING, BLEACHING, AND DYEING," to be as follows:-
My improvements in sizing machines consists in feeding the said
machines by bobbins of yarn, which are brought direct from the spinning
or winding machines, thereby dispensing with the beaming machine or
the warping mill heretofore employed.

page_text: My Invention consists also in drying the yarn after it has been sized,
dressed, bleached, or dyed by means of currents of heated or dry air,
which are produced by the exhaustion of a fan or other apparatus for
exhausting air.
A convenient mode of performing my Invention is as follows:-The
yarn to be dried is brought into a chest divided into any convenient
number of compartments; the yarn is guided over rollers so as to pass
through the said compartments in order to expose a large surface to the
action of the air. The heated or dry air is supplied through a pipe
which opens into one of the compartments, and the current necessary
for causing the air to circulate through all the compartments is produced
by a fan or by pumps or other equivalents.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Lord in the Great Seal Patent Office on
the 9th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
LORD, of Todmorden, in the County of York, Machine Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of January, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Edward Lord, Her special
licence that I, the said Edward Lord, my executors, administrators,
and assigns, or such others as I, the said Edward Lord, 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 SIZING
MACHINES AND FOR APPARATUS FOR DRYING YARN IN THE PROCESSES OF SIZING,
DRESSING, BLEACHING, AND DYEING," upon the condition (amongst others)
that I, the said Edward Lord, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and

page_text: 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 Edward Lord, 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 improvements in sizing machines consist in feeding the said
machines by bobbins of yarn, which are brought direct from the spinning
or winding machines, thereby dispensing with the beaming machine and
the warping mill heretofore employed.
My Invention consists also in drying the yarn after it has been sized,
dressed, bleached, or dyed by means of currents of heated or dry air,
which are produced by the exhaustion of a fan or other apparatus for
exhausting air.
And in order that my Invention may be fully understood I will proceed
to describe the accompanying Sheet of Drawings.
a, a, are rows of bobbins of yarn, which are brought direct from the
spinning or winding machines and arranged in vertical, diagonal, or
horizontal rows to form a creel containing the required number of ends
for the warp. The yarns from these bobbins are passed through a reed
to distribute them evenly across the guide roller b, from whence they
pass in the ordinary manner into the size trough c. When the size has
been applied to the yarn it is guided over the roller d into the chest e,
which is divided into two or more compartments by partitions, as shewn
at g; the yarn is taken from the roller d under and around the ribbed
rollers placed at opposite ends of the chest, so as to expose the
desired surface to the action of the heated air in the chest. After the
yarn has traversed to and fro through the chest it is taken over the guide
roller h, and thence to the ordinary warp beam i which revolves between
the lap rollers j, j.
The air is heated or dried before it is supplied to the chest e in the
following or in any other convenient manner:- is a chamber con-

page_text: or dried enters the chamber k at 1, and after passing through the
chamber it enters the chest e at the opening e¹. The lower end of the
chest e is in communication with the exhausting fan m, which in
revolving causes a partial vacuum, which produces the requisite current
for drawing the air through the chamberk and the compartments of
the chest e.
The circulation of the air may also be promoted by means of air
pumps or other equivalents.
Having thus stated the nature of my Invention and described a con-
venient mode of performing the same, I wish it to be understood that my
improved mode of feeding sizing machines may be applied to all sizing
machines of the ordinary construction that are now fed by warp beams,
and that my improved mode of drying the yarn may be applied to yarn
coming from any dressing, bleaching, or dyeing machine as well as to
yarn from the sizing machine as described. I would also remark that I
do not limit myself to any particular arrangement of the bobbins in the
creel for supplying the yarns to the sizing machine, nor to the mode of
exhausting the air in the drying chest, and I claim,―
| First. Supplying yarn to sizing machines in the form of a warp from
bobbins, whereby the warp beams and the beaming machine and
warping mill on which they are produced may be dispensed with.
And, Secondly. Producing the currents of heated or dry air for drying
yarn after it has been sized, dressed, bleached, or dyed by exhaustion,
as described and shewn in the Drawing or any equivalent thereof.
In witness whereof, I, the said Edward Lord, have hereto set my
hand and seal, this Seventh day of July, One thousand eight
hundred and seventy-four.
