IMPROVEMENTS IN MACHINERY FOR STEAMING TEXTILE FABRICS AND YARNS OR WARPS, AND IN APPARATUS CON- NECTED THEREWITH
Year: 1878

page_text: LETTERS PATENT to William Holt, of Halifax, in the County of York, Dyer
and Finisher, for the Invention of IMPROVEMENTS IN MACHINERY FOR
STEAMING TEXTILE FABRICS AND YARNS OR WARPS, AND IN APPARATUS CON-
NECTED THEREWITH."
Sealed the 1st April 1879, and dated the 4th October 1878.
PROVISIONAL SPECIFICATION left by the said William Holt at the
Office of the Commissioners of Patents on the 4th October 1878.
WILLIAM HOLT, of Halifax, in the County of York, Dyer and Finisher. ."IM-
PROVEMENTS IN MACHINERY FOR STEAMING TEXTILE FABRICS AND YARNS OR WARPS,
AND IN APPARATUS CONNECTED THEREWITH."
This Invention relates to that class of machinery consisting of two perforated
cylinders arranged concentrically on the same axis, capable of revolving in a closed
chamber and having in connextion therewith apparatus for cutting the fabric as it
issues from the casing or chamber. My improvements consist, firstly, in the use of
stretching rollers for guiding the fabric on to the steaming cylinder, and also for
stretching the same as it issues therefrom to the cuttling apparatus. These rollers
are composed of a series of lags divided in the middle, and having studs at the
outer ends which enter cam grooves, so shaped that as the rollers revolve the lags
meet in the centre at the upper side of the roller and separate on the under side,
so that the cloth when passing underneath the roller is opened out in the direction
of its width.
Secondly. I place the upper part of the casing on hinges, so that when it is
necessary to remove the same it may be turned back instead of having to be raised
by a crane and kept in position by guide rods as hitherto.

page_text: Thirdly. I employ break rollers to regulate the tension of the cloth during its
entrance and exit from the machine, and
Fourthly. I so arrange the driving pulleys that the main driving belt will
communicate motion to the steam cylinders and also to the winding-off roller.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Holt in the Great Seal Patent Office on the 4th April

issues from the casing or chamber.
In the accompanying Sheets of Drawings I have shewn such a machine with my
improvements applied, Fig. 1 being a side elevation; Fig. 2, a plan view; and
Figs. 3 and 4 are details of certain parts drawn on an enlarged scale.
My improvements consist, firstly, in the use of stretching rollers for guiding the
fabric on to the steaming cylinder, and also for stretching the same as it issues
therefrom. These rollers are indicated in the general views of the machine by the
letter A, and are shewn in detail in Figs. 3 and 4. They are composed of a series
of lags B divided in the centre and having studs C at the outer ends which enter
fixed can grooves D, so shaped that as the rollers revolve the lags meet in the
centre at the upper side of the rollers and separate on the under side, so that the
cloth when passing underneath the roller is opened out in the direction of its
width.
Secondly. My improvements consist in mounting the upper part of the casing E
on hinges, so that when it is necessary to remove the same it may be turned back
as shewn in dotted lines, instead of having to be raised by a crane and kept_in
position by guide rods as hitherto. The hinges are indicated by the letter F. For
keeping the lid down when the pressure of steam is on, I may employ pin and
cotter G, or bolts, screws, and nuts may be used for the same purpose.
Thirdly. In order to regulate the tension upon the cloth during the operation of
winding on or off the steam cylinder, I employ a break H acting upon the roller H³,
upon which pressure may be placed by means of moveable weights hanging upon
the lever J to which the break is fixed.
Fourthly. My improvements consist in arranging the driving pulleys so that the
main driving belt will communicate motion to the steam cylinders and also to the
winding-off roller. The pulleys L, M, are fast together but loose upon the cylinder
shaft, and from the pulley M motion is communicated to one of the fast and loose
pulleys upon the shaft of the winding-off roller N.
Having thus described the nature of my Invention, and the manner in which the

page_text: same is to be performed or carried into practice, I would have it understood that I
do not confine myself to the precise details of construction or arrangement, as the
same may be varied, neither do I lay claim to the whole of the parts herein shewn,
but what I claim as my Invention and consider to be new is,-
The application to steaming apparatus of the several improvements herein
enumerated, as and for the purpose herein shewn and described.
In witness whereof, I, the said William Holt, have hereunto set my hand
and seal, this Second day of April, in the year of our Lord One thousand
eight hundred and seventy-nine.
WILLIAM HOLT. (L.S.)
