PROVISIONAL SPECIFICATION.
Improvements in Spreading and Drying Machines Used in the
Manufacture of Waterproof Fabrics.
We, JAMES WOOD, Manager, and JAMES ROBINSON, of the firm of Broadhurst and
Company, of Bradford, Manchester, in the County of Lancaster, Manufacturers
of India Rubber Goods, do hereby declare the nature of this invention to be as
follows:-
In the invention for which we applied for Letters Patent numbered 1320 on the
24th January 1889 we describe our improvements as consisting chiefly in the use
and application of a movable spreading appliance employed in conjunction with a
rotatory drying cylinder. In this arrangement after the fabric has been passed over
the spreading roller round the.drying cylinder and traversed through the machine in
one direction we move the spreading appliance to the other end of the machine and
reverse the direction of rotation of the drying cylinder so as to reverse the traverse
of the fabric while the spreading operation is being repeated.
Our present improvements consist mainly in employing a separato spreading
appliance at each end of the machine so as to avoid the waste of time caused by
having to constantly change the position of the spreading appliance from one end of
the machine to the other.
In carrying out our improvements we conduct the fabric after it has been coated
or spread on to the drying cylinder with which it lies in contact for about three-
quarters of its circumference, the fabric then passes over guide rollers by which it is
guided on to the taking up roller which is driven in any convenient manner proferably
from the drying cylinder.
When the fabric has been coated and wound upon the taking up roller, the
spreading gauge is raised and that at the other end of the machine is adjusted.
The guide rollers are then removed to slacken the ordinary wrapper cloth after
which they are placed in bearings on the other side of the cylinder to guide the fabric
in the other direction. The belt is now removed from the roller on which the cloth is
wound to the corresponding roller at the other end of the machine which becomes
the taking up roller. The machine is now ready to be started in the opposite
direction the fabric being coated and dried in its traverse to the taking up roller
he operation being repeated as often as necessary.

Improvements in Spreading and Drying Machines Used in the
Manufacture of Waterproof Fabrics.
We, JAMES WOOD, Manager, and JAMES ROBINSON, of the firm of Broadhurst and
Company of Bradford, Manchester in the County of Lancaster, Manufacturers of
India Rubber Goods, 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 :-
In the invention for which we applied for Letters Patent numbered 1320 on the
24th January 1889 we describe our improvements as consisting chiefly in the use
and application of a movable spreading appliance employed in conjunction with n
rotatory drying cylinder. In this arrangement after the fabric has been passed over
the spreading roller round the drying cylinder and traversed through the machine in
one direction we move the spreading appliance to the other end of the machine and
FD77

page_text: reverse the direction of rotation of the drying cylinder so as to reverse the traverse
of the fabric while the spreading operation is being repeated.
Our present improvements consist mainly in employing a separate spreading
appliance at each end of the machine so as to avoid the waste of time caused by
having to constantly change the position of the spreading appliance from one end of
the machine to the other.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying two Sheets of Drawings reference being had
to the figures and letters marked thereon.
Figure 1 is a side elevation and Fig. 2 a plan of a single cylinder spreading and
drying machine embodying our present improvements.
:
In these views the frame a of the machine has bearings for the batch
rollers cc which are placed at opposite ends of the machine and act alternately as
batch rollers and taking up rollers; the fabric d to be coated with india rubber
Near each end of
composition is in the Drawings shown batched upon the roller c.
the machine is placed an appliance for spreading the india rubber composition upon
the fabric; each appliance consists of a spreading roller e or el and a gauge for f
which is arranged to swivel in slide blocks g or g' and can be adjusted vertically
when required by screws h or h¹.
The steam heated drying cylinder i is placed in the centre of the machine and is
driven in either direction as required by means of a belt j and a pulley fixed on
the cylinder shaft; k, k³, k², k³, are guide rollers over and under which the fabric d
passes on its way through the machine. When the fabric dis batched upon the
roller c as shown it is taken over the spreading roller e the gauge being set in its
vertical working position and from the roller e the fabric passes over and almost
entirely round the drying cylinder i, thence over the guide roller & and under the
guide roller over the spreading roller el (the gauge being raised as shown) and
is finally wound upon the roller c' which in this instance acts as the taking up roller
and is therefore driven by a pulley c² and a band from a pulley on the cylinder
shaft. The "dough" or india rubber composition is applied to the fabric in the
usual way just before the fabric passes between the gauge and spreading roller e
and after all the fabric to be treated has passed through the machine and been batched
upon the roller cl the end of the wrapper cloth is led back from the roller c' directly
over the spreading roller e' to and nearly round the cylinder over the guide roller k
and under the guide roller ³ over the spreading roller e to the roller c which has
now to act as the taking up roller. The gauge is moved into its vertical working
position and the gauge is raised or swivelled to one side clear of the fabric. The
band is now taken off the pulley c² and placed on a pulley on the roller c and
when this has been done the drying cylinder is rotated in the opposite direction
whereby the fabric is drawn through the machine in the reverse direction to that
indicated by the arrow, Fig. 1 and the dough or india rubber composition is
applied to the fabric and spread by the gauge and roller e¹.

The spreading operation can be repeated as often as required by simply reversing
the motion and the course of the fabric over the guide rollers in the manner above
described without taking the fabric out of the machine or winding it back by hand in
the ordinary way.
Having now particularly described and ascertained the nature of our said inven
Lion and in what
manner the same is to be performed we declare that wha
we claim is:-
In a spreading and drying machine the combination with a steam heated drying
cylinder, of a separate spreading appliance at each end of the machine substantially
as and for the purposes herein set forth.
