IMPROVEMENTS IN MACHINERY FOR DRYING YARNS AND OTHER MATERIALS
Year: 1858

page_text: LETTERS PATENT to Matthew Pullan, of Horsforth, near Leeds, in the
County of York, Bleacher, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR DRYING YARNS AND OTHER MATERIALS."
Sealed the 12th May 1859, and dated the 13th November 1858.
PROVISIONAL. SPECIFICATION left by the said Matthew Pullan at
the Office of the Commissioners of Patents, with his Petition, on the
13th November 1858.
I, MATTHEW PULLAN, of Horsforth, near Leeds, in the County of York,
Bleacher, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY FOR DRYING YARNS AND OTHER MATERIALS," to be as.
follows:-
My Invention consists in mounting yarns or other materials to be dried
upon heated cylinders, which revolve and carry round the yarn or other
material until the same is sufficiently dry. These heated cylinders are placed
apart from each other; and immediately between them I employ a roller or
another cylinder, (which may be heated also, if necessary,) to which is given an
oscillating motion as well as its own rotary motion, which rotary motion may
either be caused by friction of contact with the yarn or other material in
process of drying or by any ordinary gearing. This intermediate roller or
cylinder is of such a shape that it will prevent the yarn or other material

page_text: upon the heated cylinders from slipping off, and its oscillating motion is given
partly for the purpose of stretching or tightening the yarn or other material
upon the heated cylinders, and partly for the purpose of giving to a certain
extent a sudden stroke or jerk to the material, thereby opening out the threads
and giving greater facility to the drying. The cylinders are supplied with
steam in any ordinary mode; and I propose to assist the drying process as
much as possible by using heated chambers in connection with the drying
apparatus.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Matthew Pullan in the Great Seal Patent Office on the
18th May 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MATTHEW
PULLAN, of Horsforth, near Leeds, in the County of York, Bleacher, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of November, 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 Matthew Pullan, Her special license that I, the said Matthew
Pullan, my executors, administrators, and assigns, or such others as I,
the said Matthew Pullan, 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 FOR DRYING YARNS AND OTHER MATERIALS," upon
the condition (amongst others) that I, the said Matthew Pullan, 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 Patent.
NOW KNOW YE, that I, the said Matthew Pullan, 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

page_text: statement, reference being had to the Drawing hereunto annexed; and to the
letters and figures marked thereon (that is to say):-
This Invention relates to the drying of yarns or other materials in the form
of banks or endless bands by means of heated cylinders to which rotary motion
is imparted. The yarn or other material to be dried being placed over such
rollers and held at tension thereon, will be carried round by their revolution,
and a continuous heating surface being thus presented to the travelling band
or hank, the moisture will be quickly evaporated therefrom.
In the accompanying Drawing the manner in which I prefer to carry out
this object is clearly shewn; Fig. 1 being a side view, and Fig. 2 a front view
of the drying machinery. It may be here remarked that although I have in
Fig. 1 shewn but two drying cylinders, yet any required number may be
mounted in the same frame, and the yarn may be led over one or more of such
cylinders. A, A, are the heating cylinders, secured to the ends of hollow
axles A*, which are carried in bearings C in the framework B. These
cylinders are supplied with steam from a pipe D, which has branches con-
nected to the ends of the hollow axles, but in such a manner as will allow of
their revolving in their bearings. Keyed to each of the axles A* is a spur
wheel E, which receives motion through spur pinions F from a spur pinion G
on the main driving shaft H, which shaft is driven by a band from any prime
mover passing over the fixed pulley I. The yarn K is laid over the heated
cylinders in the form of hanks, and it is held at tension by the insertion of
blocks L, which are mounted loosely on dead axles M, the inner extremities
of which are carried by links jointed to the framing B, while they are further
supported by pairs of links N, the lower ends of which are jointed to a
treaddle O. This treaddle and link arrangement is simply to facilitate the
putting on and taking off of the yarn, the depression of the treaddle by the
foot of the attendant causing the block L with which it is connected to rise,
and by approaching the heated roller slacken the yarn, and allow of its removal
or facilitate the laying on of a fresh supply. The blocks L may either be
square or many sided, according to the quality of the yarn to be operated upon,
their use being not merely to hold the yarn at tension, and thus prevent it
from slipping, but also to open out the yarn by rotating with an irregular or
jerking motion (consequent on their form) through friction of contact with the
passing yarn.
Having now set forth the nature of my Invention of "Improvements in
Machinery for Drying Yarns and other Materials," and explained the manner
of carrying the same into effect, I wish it to be understood that under the

page_text: above in part recited Letters Patent I claim the means herein described for
presenting yarns and other materials which may be formed into hanks or
bands to the drying action of heated cylinders or rollers.
In witness whereof, I, the said Matthew Pullan, have hereunto set my
hand and seal, the Ninth day of May, in the year of our Lord One
thousand eight hundred and fifty-nine.
Witness to the signature of the said
Matthew Pullan,
