IMPROVEMENTS IN MACHINERY EMPLOYED FUK SIZING AND DRYING YARN.
PROVISIONAL SPECIFICATION left by the said John Bullough and
Peter Ormerod Whitehead at the Office of the Commissioners of
Patents, with their Petition, on the 20th April 1874.
We, JOHN BULLOUGH, of Accrington, in the County of Lancaster,
Engineer, and PETER ORMEROD WHITEHEAD, of Belmont, Rawtenstall,
in the same County, Engineer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY EMPLOYED FOR SIZING AND DRYING
YARN," to be as follows:-
:-
This Invention has for its object the construction of apparatus and
the employment of means designed to secure the drying of yarn after
sizing.
We employ a box or casing which is divided by a partition or partitions,
or midfeather, by preference placed and secured longitudinally within

page_text: and extending nearly the whole length of the box or casing, and within
which is also a steam or heated cylinder or air heating apparatus having
air pipes or air passages therethrough. Guide rollers are provided, these
being outside the box or casing in order to facilitate access to the yarn
when "lappers" are formed without the necessity for opening the box
or casing. An exhaust fan is employed whereby a current of air is
drawn through the entrance way to the box or casing through the air
pipes of the steam heated cylinder or air-heating apparatus to the
interior of the box or casing, and is turned or diverted by the midfeather
or midfeathers or divisions into and along the several compartments
circulating through the box or casing until reaching the exhaust fan,
by way of which it passes outwards. The yarn after being sized enters
through a slit or narrow opening, traverses the length of the box or
casing and out to the extreme or the opposite end through a similar slit or
opening and over another guide roller and again enters the box or casing
by way of another slit, and so on, being by the several guide rollers
caused to pass and repass through the. box or casing and its several
compartments as many times as requisite to secure its being dryed by
exposure to the air heated whilst passing, or being drawn by the action
of the exhaust fan through the air pipe of the steam heated cylinder or
air-heating apparatus, and through and along the several compartments
of the yarn drying box or casing.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Bullough and Peter Ormerod Whitehead
in the Great Seal Patent Office on the 20th October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
BULLOUGH, of Accrington, in the County of Lancaster, Engineer, and
PETER ORMEROD WHITEHEAD, of Belmont, Rawtenstall, in the same
County, Engineer, send greeting.
:
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Twentieth day of April, 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 us, the said John Bullough and Peter
Ormerod. Whitehead, Her special licence that we, the said John

page_text: Bullough and Peter Ormerod, our exccutors, administrators, and
assigus, or such others as we, the said John Bullough and Peter
Ormerod Whitehead, our exccutors, administrators, and assigns, should
in 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 EMPLOYED FOR SIZING AND DRYING
YARNS," upon the condition (amongst others) that we, the said John
Bullough and Peter Ormerod Whitehead, our executors or administrators,
by an instrument in writing under our, or their, or one of 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 John Bullough and Peter Ormerod
Whitehead, do hereby declare the nature of our 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 :-
-
This Invention has for its object the construction of apparatus and
the employment of means designed to secure the drying of yarn after
sizing.
We employ a box or casing which is divided by a partition or partitions,
or midfeathers, by preference placed and secured longitudinally with and
extending nearly the whole length of the box or casing, and within
which is also a steam or heated cylinder or air-heating apparatus having
air pipes or air passages therethrough. Guide rollers are provided, these
being outside the box or casing in order to facilitate access to the yarn
when "lappers" are formed without the necessity for opening the box
or casing. An exhaust fan is employed whereby a current of air is
drawn through the entrance way to the box or casing through the air
pipes of the steam heated cylinder or air-heating apparatus to the interior
of the box or casing, and is turned or diverted by the midfeather or mid-
feathers or diversions into and along the several compartments circulating
through the box or casing until reaching the exhaust fan, by way of
which it passes outwards. The yarn after being sized enters through a
slit or narrow opening, traverses the length of the box or casing and out

page_text: to the exterior on the opposite end through a similar slot or opening and
over another guide roller and again enters the box or casing by way of
another slit, and so on, being by the several guide rollers caused to
pass and repass through the box or casing and its several compartments
as many times as requisite to secure its being dried by exposure to the
air heated whilst passing, or being drawn by the action of the exhaust
fan through the air pipes of the steam heated cylinder or air-heating
apparatus, and through and along the several compartments of the yarn
drying box or casing.
Such being the nature and object of this our said Invention, we will
now proceed to describe the same in detail, and in order that the Inven-
tion may be fully understood we have hereunto annexed a Sheet of
Drawings illustrating the construction of the apparatus, and have marked
the figures with letters of reference, the same letter referring to the same
part in each Figure.
Figure 1 is a longitudinal vertical section shewing construction and
interior arrangements.
Figure 2 is a cross vertical section of the apparatus.
A, the box or casing divided by the partitions or midfeathers B, C, D.
The tubular cylinders E, F, G, and H are placed, as shown, within the
box or casing A, such cylinders being heated by steam or other means
conducted to and conveyed from the said cylinders by ordinary inlet and
outlet pipes, the cylinders being connected with each other, or separate
heat supplying and discharging pipes may be employed in connection
with cach cylinder. At J is shewn an exhaust fan for drawing the air
through and from the box or casing A, and inasmuch as the only inlet
for air is by way of K and through and along the tubes e, e, of the
cylinders E, F, G, and H (or one or more of them), the air becomes heated,
and during its course to the fan J it is diverted and turned by the several
partitions or midfeathers, as shown by the arrows, the yarn L being
directed by the guide or conducting rollers M, M, along the several
heated air ways or passages and so exposed to and dried by the air
heated as and by the apparatus described, and by the heat given off or
arising from the exterior surface of the said cylinders. The guide or
conducting rollers M, M, may be placed outside the box or casing A to

page_text: facilitate access thereto for any purpose without its being necessary to
open the box or casing, and in order that the said rollers may be kept
cool so as to prevent the size adhering thereto, or such rollers may be
(as shewn) enclosed in small outer compartments R, R, having hinged
or sliding lids S, slits or narrow openings n, n, n, are provided for the
entrance and exit of the yarn on its way from the unsized beams T, T,
to the weavers or finished beam W.
Having thus fully described the nature and particulars of this our said
Invention, together with the manner in which the same is to be per-
formed or carried into practical effect, we would have it understood that
we lay no claim per se to the use of air-heating apparatus, nor to the use
of the fan, but we do claim, the construction and use of tlie box A in
connection and combination with air-heating apparatus, exterior guide
rollors M, M, and exhaust fan, acting in the manner and for the purpose
herein fully described and illustrated as constituting and being our
Invention.
In witness whereof, I, the said Peter Ormerod Whitehead, have
for and on behalf of the said John Bullough and myself, hereunto
set my hand and seal, this Fifteenth day of October, in the
year of our Lord One thousand eight hundred and seventy-
four.
