PROVISIONAL SPECIFICATION left by Joseph Harrison and John Oddie
at the Office of the Commissioners of Patents,. with their Petition, on the
12th January 1855.
We, JOSEPH HARRISON, and JOHN ODDIE, both of Blackburn, in the County
of Lancaster, Machinists, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINES FOR SIZEING, DRYING, AND OTHERWISE PREPARING
YARNS OR THREADS FOR WEAVING," to be as follows:-
Our improvements relate to drying machines, or to drying yarns or threads
operated upon in sizeing or dressing machines, and to a mode of boiling the size
while it is being applied. These objects have been generally accomplished
hitherto by the heat of steam, which in the first-mentioned operation (drying)
is fed into boxes or cylinders, near or against the exterior of which the yarn or
threads (after the application of size) is passed, and is thus dried. There are
several inconveniences in applying steam to this purpose, as well as objections,
on account of its limited heating power at low pressures, and the danger of
explosion of the cylinders or vessels employed, which frequently occurs.
object of our improvements is to remedy these inconveniences and objections,
as well as effect an economy in the cost of the process, which we propose to
accomplish by the application of heat (arising from combustion) or heated air,
or the heated products of combustion. The material which we believe to be
most economical and conveniently applied to effect this purpose is coal, or other
The

cylinders or boxes, having. proper arrangements for the due supply of fresh air,
or at the exterior of the cylinders or boxes, having arrangements for conducting
the heated products of combustion into and through the interior of the cylinders
or boxes; or air may be heated by the combustion of gas or otherwise, and
be drawn or injected into the cylinders or boxes employed: The size may be
boiled by the combustion of jets of gas arranged under the box which contains
it. The temperatures of the vessels may be regulated by increasing or
diminishing the consumption of gas, or by increasing or diminishing the supply
of hot or cold air, and it may be ascertained by, thermometers, which may be
arranged with a piston acting upon apparatus connected with valves, so as
to increase or diminish the supply of gas, or hot or cold air, according to
the decrease or increase of temperature registered by the thermometer, and
by this means the temperature will be self-regulating. Our Invention also
consists in arranging drying apparatus, so that it may be covered in; by cases
or boxes (which niay be made non-conducting) to exclude them from the con-
densing action of the atmosphere; or it consists in an arrangement of a series
of rollers, over and under which the yarn to be dried is. made to pass, so as to
expose as large an amount of yarn as required in as small a space as possible
to a drying action, the series of rollers being covered over to prevent as far
as possible the condensing action of the atmosphere by moveable cases or
boxes; the air in the interior of which being made and kept hot-by-hot air
injected or drawn into them, or by means of interior heating boxes, pipes,-or
channels, or otherwise. And our Invention also consists in subjecting yarn
or threads to the action of a draught or blast of cold air, in' an arrangement
of apparatus similar to that just referred to, for subjecting it to the action of
heat or heated air, with divisions or partitions in the boxes or cases, arranged
to concentrate and divert the draught or blast, so as to cause the yarn or
thread to be subjected to its action over the entire length exposed in the cases
or boxes. It also consists in combining the two arrangements for drying by
heat (or by draughts or blasts of hot air) and cold air together, the yarn or
threads passing from the hot to the cold air arrangement.
