page_text: LETTERS PATENT to Joseph Parkinson, of West Leigh, in the County of
Lancaster, for an Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF
APPARATUS EMPLOYED IN STEAMING TEXTILE FABRICS."
PROVISIONAL SPECIFICATION left by the said Joseph Parkinson at the
Office of the Commissioners of Patents on the 17th February 1881.
"
JOSEPH PARKINSON, of West Leigh, in the County of Lancaster. 'IMPROVE-
MENTS IN THE CONSTRUCTION OF APPARATUS EMPLOYED FOR STEAMING TEXTILE
FABRICS."
.This Invention is designed principally for the steaming of calicoes printed with
indigo, for the purpose of fixing the color, but it may also be employed for steaming
other textile fabrics where a dry steam heat is required.
The apparatus consists externally of a box or vessel of cast iron or other suitable
material, closed at the bottom and open at the top. Above the bottom of this
vessel is a false bottom, which is perforated all over, so that steam being admitted
to the space below the false bottom will pass through the same into the vessel.
Above the false bottom is a copper cylinder (about six inches diameter) extending
across the centre of the vessel, and above the top of the vessel is a steam pipe of
similar diameter, which is connected with the copper cylinder and also by a supply
pipe with the boiler.
Sloping upwards from the top of the box or vessel (and nearly touching the
steam pipe on each side) are two flat steam chests. The calico or other fabric
passes into the box or vessel by the space between the sloping steam chest and one
side of the steam pipe, then downwards under the copper cylinder, and up again
and out through the space between the steam pipe and the other sloping steam
chest.
Inside the vessel and on each side of the fabric as it passes down to and up from
the copper cylinder are two flat steam chests connected to the horizontal steam pipes
and intended to keep the steam in the vessel dry during its action on the printed
fabric.
The various steam chests and pipes and the copper cylinder are all provided with
small pipes and taps for drawing off the condensed water therefrom.
Carrier rollers are provided for conducting the calico or other fabric to and from
the steaming box or vessel, and a pair of drawing rollers are employed for carrying
the fabric through the apparatus at the required speed.

"IMPROVE.
MENTS IN THE CONSTRUCTION OF APPARATUS EMPLOYED FOR STEAMING TEXTILE
FABRICS."
This Invention is designed principally for the steaming of calicoes printed with
indigo, for the purpose of fixing the color, but it may also be employed for steaming
other textile fabrics where a dry steam heat is required.
In the annexed Drawing Fig. 1 is an elevation, Fig. 2 a vertical section, and
Fig. 3 a horizontal section of the improved apparatus, which consists externally of
a box or vessel a, a, of cast iron or other suitable material, closed at the bottom
and open at the top. Above the bottom of this vessel is a false bottom b, b, which
is perforated all over, so that steam being admitted to the space c, c, below the
false bottom b, b, will pass through the same into the main chamber d, d, of the
vessel.
Above the false bottom b, b, is a copper cylinder e, e, (about six inches in
diameter), extending across the centre of the main chamber d, d, and above the top
of the vessel a, a, is a steam pipe f, f, of similar diameter, which is connected
with the copper cylinder e, e, by a pipe g, g, and also by a supply pipe h, h, with
the boiler.
-
Sloping upwards from the top of the vessel a, a, (and nearly touching the steam
pipe ff, on each side) are two flat steam chests i, ix, which are also connected to
the steam supply pipe h, h. The calico or other fabric passes into the main
chamber d, d, of the vessel by the space between the sloping steam chest i and one
side of the steam pipe f, f, then downwards under the copper cylinder e, e, and up
again and out through the space between the steam pipe f, f, and the other sloping
steam chest ix.
Inside the vessel a, a, and on each side of the fabric as it passes down to and up
from the copper cylinder e, e, are two flat steam chests k, l, connected to horizontal
steam pipes, l, and intended to keep the steam in the vessel dry during its action
on the printed fabric.
The various steam chests and pipes and the copper cylinder are all provided with
small pipes 7, m, and taps for drawing off the condensed water therefrom.
Carrier rollers n, n, are also provided for conducting the calico or other fabric to a
and from the steaming box or vessel a, a, and a pair of drawing rollers o, o, (Fig. 2)
are employed for carrying the fabric through the apparatus at the required
speed.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I wish it to be understood that I claim as iny Invention, the novel construc-
tion of apparatus for steaming textile fabrics, as hereinbefore described and
illustrated by the Drawings, or any mere modification or imitation thereof, con-
structed and operating in substantially the same manner.
In witness whereof, I, the Joseph Parkinson, have hereunto set my hand
and seal, this Fifteenth day of August, in the year of our Lord One
thousand eight hundred and eighty one.
