PROVISIONAL SPECIFICATION.
Improvements in Expanders for Fabric Drying Machines or
Apparatus.
We, FREDERICK SCOTT, Calico-printer, and EDWIN HOWARD, Foremau-
finisher, both of Gale Printworks, Littleborough, WILLIAM PICKUP, and
WILLIAM KNOWLES, both of Orchard Street, Pendleton, Engineers, all in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object the application, to a machine or apparatus for
drying fabric in continuous length, of an expander constructed as follows:-
On a bed plate, secured to any suitable part of the respective machine or
apparatus, are rendered adjustable to and from each other by means of a right and
left hand threaded spindle, two pedestals, each of which is pivoted to a standard
having arms. The base of such standard is furnished with a quadrant in gear with
a worm fixed on a cross shaft by means of which the angular position of the said
standards relative to the fabric passing between the same may be varied at will for
the purpose hereinafter described. In each of the said standards is mounted a
short shaft carrying a pulley of large diameter arranged to rotate on the inner side
of the said standard whilst its arms carry studs on which revolve loosely small
carrier pulleys rendered radially adjustable. The said large pulleys serve to
support and stretch the fabric passed through the expander, a belt being employed
on the fabric to retain it in frictional contact with the said large pulleys which
belt is guided and retained at the required tension by means of the said carrier
pulleys.
The said standards being rendered adjustable on the said pedestals as aforesaid
the angular position of the said pulleys and belt relative to the fabric can be
altered at will so as to stretch the fabric crosswise more or less as may be required
on being passed through the expander.
By means of universal joints the shafts of the said large pulleys are each
connected to a driving shaft onto one of which is secured a strap and a chain pulley
whilst on the other a chain pulley only.
In the pedestals aforesaid is mounted a cross shaft carrying at each end a chain
pulley, the one on the driving side of the expander having rotary motion imparted
by means of a chain from the respective chain pulley and that on the other side
imparting motion by another chain to the respective driving shaft.

We, FREDERICK SCOTT, Calico-printer, and EDWIN HOWARD, Foreman-
finisher, both of Gale Printworks, Littleborough, WILLIAM PICKUP, and
WILLIAM KNOWLES, both of Orchard Street, Pendleton, Engineers, all in the
County of Lancaster, 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 :--
This invention has for its object the application, to a machine or apparatus for
drying fabric in continuous lengths, of an expander of certain construction.
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 view, Fig. 2 an end of an expander constructed in accordance
with our invention.
Figs. 3 & 4 are respectively a side view partly in section and an end view of a
modification thereof.
Fig. 5 shows one method of applying the said expander to a drying machine.
In carrying out our invention and referring to Figs. 1, 2 & 5, we render adjust-
able to and from each other, on a bed plate a, secured to any suitable part of the
respective machine or apparatus b, by means of a right and left hand threaded
spindle c, two pedestals d upon each of which is pivoted a standard e having arms e¹.
The base e² of such standard is furnished with a quadrant in gear with a worm g
fixed on a cross shaft by means of which the angular position of the standards e
relative to the fabric i passing between the same may be varied at will for the
purpose hereinafter described. In each of the standards e is mounted a short
shaft k carrying a pulley corresponding in diameter with that of the drying
cylinder arranged to rotate on the inner side of the standard e whilst its arms
carry studs m on which revolve loosely small carrier pulleys n rendered radially
adjustable. The large pulleys I serve to support and stretch the fabric i passed
through the expander a belt 12 being employed on the fabric to retain it in
frictional contact with the large pulleys which belt is guided and retained at the
required tension by means of the carrier pulleys n.
The standards e being rendered adjustable on a pivot d' upon the pedestals das
aforesaid the angular position of the said pulleys and belt / relative to the fabric i
can be altered at will so as to stretch the fabric i crosswise more or less as may be
required on being passed through the expander.
By means of universal joints o the shafts k of the large pulleys are each
connected to a driving shaft o' mounted in bearings o' fixed or formed upon the bed
plate a. Upon one of the shafts o¹ is secured a strap and a chain pulley p, q,
respectively, whilst on the other a chain pulley g' only.
In the pedestals d is mounted a cross shaft r carrying at each end a chain
pulley g, the one on the driving side of the expander having rotary motion
imparted by means of a chain q³ from the respective chain pulley g and that on
the other side imparting motion by another chain to the respective driving
shaft o'.
According to the modifications shown in Figs. 3 & 4, we may dispense with the
universal joint, chain wheels and respective shaft hereinbefore referred to and
mount the pulleys in bearings each pulley boss being made hollow to admit of
the shaft o, extending from one end of the expander to the other and rotating
therein.

page_text: Each pulley has a bevel wheel t secured upon its boss gearing into a carrier
bevel wheel and this into a bevel wheel t keyed upon the shaft o', by means of
which motion is transmitted to the pulleys one end of the said shaft o' being
furnished with a driving pulley p.
The bracket e is rendered movable on a
pivot d and carries the quadrant f by means of which the pulleys / can be
angularly adjusted as may be required the hollow boss 1 of the latter permitting of
such movement.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is-
In fabric drying machines or apparatus the use and application of a fabric
expander constructed and operating substantially as described and illustrated in
annexed drawing.
