IMPROVEMENTS IN APPARATUS FOR DRYING YARN
Year: 1879

page_text: LETTERS PATENT to Richard Ecroyd, of Lomeshaye, near Burnley, in the
County of Lancaster, Manufacturer, for the Invention of "IMPROVEMENTS IN
APPARATUS FOR DRYING YARN."
PROVISIONAL SPECIFICATION left by the said Richard Ecroyd at the Office
of the Commissioners of Patents on the 22nd October 1879.
RICHARD ECROYD, of Lomeshaye, near Burnley, in the County of Lancaster,
Manufacturer. "IMPROVEMENTS IN APPARATUS FOR DRYING YARN."
The object of this Invention is to dry the yarn much more efficiently than
hitherto by means of a blower in lieu of a fan, as hitherto in use, but also in
combination with an arrangement of pipes, whereby the air is forced upon both
sides of the yarn; these pipes are either perforated or prepared with suitable
longitudinal slits or apertures, and are fed from one or two larger main pipes
connected to the blower. If the yarn is passed longitudinally, the pipes are above
and below, not quite opposite each other; in case the yarn is passed upwards and
downwards, one pipe is on one side and the other on the opposite. In some cases
the yarn is made to travel partly in a horizontal direction, and partly in an upward
and downward direction, but in any case by my improvements there is a perforated
pipe connected to blower on each side of the yarn. I do not claim novelty as
regards the direction of the yarn, but the arrangement of the pipes in the positions
indicated, and varying in number as required, in combination with the blower is
novel and useful.

the said Richard Ecroyd in the Great Seal Patent Office on the 21st April

RICHARD ECROYD, of Lomeshaye, near Burnley, in the County of Lancaster,
Manufacturer. "IMPROVEMENTS IN APPARATUS FOR DRYING YARN."
The object of this Invention is to dry the yarn after passing through the size
more effectually than hitherto by means of a blower in combination with an
arrangement of pipes, whereby the air is forced upon both sides of the yarn.
My object can be accomplished in the following manner, and is illustrated by
Figure 1, which is a longitudinal section of such portions of a sizing machine, as
are required to explain my Invention; Figure 2 is a plan of the main and
distributing pipes that are connected to an ordinary blower.
The framework of the apparatus is indicated by the letter A, and the stands or
brackets B have journals formed at the top, which carry the swifts C. The bottom
series of swifts C are also carried by suitable brackets attached to frame A, the
whole of which are enclosed within a casement. The yarn passes from the size
box and through the pressure rollers D to the first swift C' in the ordinary manner,
then round the various swifts in the direction as indicated by the arrows to the
ordinary warp beam at the opposite end of the apparatus.
A blower is connected to the main pipe E, to which are attached a series of
smaller or distributing pipes F, having perforations or slits near the top, and in
such a position that the current of air, which may be heated or otherwise, passing
out of the said perforations or slits blows upwards upon the yarn G, and dries the
same whilst travelling from one end of the apparatus to the other before passing
over swift H to the warp beam, which is actuated in the ordinary manner.
Having thus described the nature and manner in which my Invention may be
carried into practical effect, I wish it to be understood that I do not claim any
novelty as regards the direction in which the yarn passes through the apparatus, as
the same may be conducted in a horizontal or angular direction. without departing
from the characteristic nature of my Invention; but what I believe to be novel
and claim as my Invention is,―
The drying of yarn after sizing by means of air supplied by a blower, the air
being distributed by branch perforated pipes arranged substantially in the manner
before described.
In witness whereof, I, the said Richard Ecroyd, have set my hand and seal,
this Nineteenth day of April, in the year of our Lord One thousand eight
hundend
