PROVISIONAL SPECIFICATION.
Improvements in Machines for Drying and Ageing Woven or Spun
Fibres.
We, THOMAS BARCROFT of 68 Dover Street, Cleveland, Crumpsall, Engineer, and
THOMAS BARCROFT junior, of 70 Dover Street, Cleveland, Crumpsall, Engineer, both
in the County of Lancashire, do hereby declare the nature of our invention to be as
follows:-
The object of our invention is the construction of a machine whereby woven or
spun fibres can be dried or aged in a continuous and more uniform and effective
manner, and at a less cost than heretofore has been the case.
Our invention consists principally in the construction application, and arrangement
of a series of winches suitably rotated either in combination with a series of hot air
pipes or by itself in a hot or dry air chamber, by means of which the woven or spun
fibres such as fabric or warp is treated in a continuous manner, and both sides
thereof exposed uniformly to the hot or dried air.
In carrying out our improvements, we form the said winches preferably by fixing
a suitable number of V shaped longitudinal arms around a rotating axis.
When employing these winches in combination with a series of hot or dry air
pipes the said axis is formed to constitute a spray pipe or a cylinder, as deemed
desirable for the various classes of woven or spun fibres to be dryed or aged which
by means of a stuffing box, is brought in connection with a supply pipe into which
hot or dried air is drawn or forced by suitable means.
The said winches are arranged to rotate horizontally in bearings on a suitable
frame in a zig-zag manner, in one or more horizontal, vertical, or inclined series, the
woven or spun fibres being passed alternately under and over the said winches.
In order to pass the woven or spun fibres in an open state over the said winches,
a suitable opener is employed at the feeding end of the machine and if deemed neces-
sary also between or after a series of winches, and to ensure the woven or spun
fibres bearing against the winches as little as possible, the longitudinal cross bars
are arranged to present their edges to the same.

Improvements in Machines for Drying and Ageing Woven or Spun
Fibres.
We THOMAS BARCROFT, of 68, Dover Stroet, Cleveland Crumpsall, Engineer, and
THOMAS BARCROFT, junior, of 70 Dover Street Cleveland, Crumpsall, Engineer, both
in the County of Lancashire, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The object of our invention is the construction of a machine whereby woven or
spun fibres can be dried or aged in a continuous and more uniform and effective
manner, and at a less cost than heretofore has been the case.
And in order that our invention may be more fully understood we have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1. is a side elevation and Fig. 2 a plan of our improved machine.

page_text: Our invention consists principally in the construction, application and arrangement
of a series of winches a suitably rotated preferably by means of spur wheel gearing a
either in combination with a series of hot air pipes b & e or by itself in a hot or
dry air chamber, by means of which the woven or spun fibres c, such as fabric or
warp is treated in a continuous manner and both sides thereof exposed uniformly
to the hot or dried air.
In carrying out our improvements and referring to the Figures generally, we
form the said winches a preferably by fixing a suitable number of V shaped longi-
tudinal bars a¹ around a rotating axis d. When employing these winches a in
combination with a series of hot or dry air pipes 6 as illustrated in the drawing,
the said axis d is formed to constitute a spray pipe or a cylinder, as may be deemed
desirable for the various classes of woven or spun fibres to be dried or aged, &
which axis, d by means of a stuffing box d¹, is brought in connection with a supply
pipe e into which hot or dry air is drawn or forced by suitable means. The said
winches a are arranged to rotate horizontally in bearings fon a suitable frame f¹
in a zig-zag manner, in one or more horizontal, vertical, or inclined series, the woven
or spun fibres c being passed alternately under and over the said winches a.
In order to pass the fabric in an open state, viz. cross-wise, expanded over the
said winches a, a suitable opener is employed at the feeding end of the machine
which opens the fabric and keeps it expanded, and if deemed necessary also between
or after a series of the winches a. To ensure the woven or spun fabres c bearing
against the winches a as little as possible, the longitudinal cross bars a¹ are arranged
to present their ✓ edges to the same. In lieu of the desired arrangement of hot
or dry air pipes b & e and hollow perforated winch axis d, one or more steam pipes b¹
may be employed between the series of winches a, as shown in dotted lines. The
woven or spun fibres c are preferably passed through the machine so as to leave it
at the end at which it is introduced, viz. it is guided over the roller g from whence
it is passed under and over the top series of winches a and over the rollers h, i, k
back under and over the bottom series of winches a and over the roller out of the
machine. It will be evident that any suitable number and series of winches a may
be employed without departing from the nature of our invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
"In machines for drying and ageing woven or spun fibres."
The employment of a series of winches a under and over which the woven or spun
fibres c pass, so as to alternately expose each side thereof to heat, in combination
with a series of hot or dry air pipes 6 &.e or with a chamber, substantially as and for
the purpose specified.
