PROVISIONAL SPECIFICATION.
A New or Improved Machine or Apparatus for Finishing Textile
Fabrics.
I, GEORGE DOUGLAS, of Bowling Dye Works, Bowling, near Bradford, in the
County of York, Dyer and Finisher, do hereby declare the nature of this invention to
be ás follows:-
This. invention relates to a new or improved machine or apparatus for finishing
textile fabrics particularly adapted to be used in conjunction with a rigging machine
such as that known as Elder's rigging machine i or other apparatus of the
same class..
"
"
The said improvements consist in the construction and arrangement of pressing
apparatus hereinafter described.
For this purpose I employ two endless cloths, felts or belts having a smooth surface
and without perceptible joint or seam. One of said cloths encircles a large
cylinder heated by steam and such cloth is kept tightly in contact with the greater
part of the periphery of said cylinder by means of suitably arranged guide and
tension rollers. The outer face of the endless.cloth is heated by passing in contact
with a steam cylinder preferably-mounted between said guide or tension rollers. The
second endless cloth does not encircle the large cylinder, but is guided by suitably
arranged guide and tension rollers in such a manner that it closely enfolds approxi-
mately the whole of that part of the first endless cloth in contact with the large
cylinder. A heating cylinder is also provided to heat the face of the second cloth.
The several parts of the above mentioned apparatus are so relatively arranged that
when the endless cloths, cylinders and minor parts are put into operation the fabric to
be pressed is fed in between said heated cloths and is thus exposed to the pressure
between them as they travel round the greater part of the periphery of the
large cylinder. The said pressure is regulated by the tension of the endless cloths.
I may use a pressure roller or rollers to directly press the endless cloths against the
large cylinder.
The above described apparatus may also be used in combination with a folding or
plaiting machine.

A New or Improved Machine or Apparatus for Finishing Textile
Fabrics.
I, GEORGE DOUGLAS, of Bowling Dye Works,. Bowling, near. Bradford, in the
County of York, Dyer and Finisher, 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 relates to a new or improved machine or apparatus for finishing
textile fabrics particularly adapted to be used in conjunction with a rigging machine
such as that known as "Elder's rigging machine" or other apparatus of the
same class..
The said improvements consist in the construction and arrangement of pressing
apparatus hereinafter described.
For this purpose I employ two endless cloths, felts or belts having a smooth face

and without perceptible joint or seam. One of said cloths encircles a large cylinder.
which maybe heated by steam and such cloth is kept tightly in contactwith the greater
part of the periphery of said cylinder by. means of suitably arranged guide and
tension rollers. The smooth outer face of the endless cloth is heated by passing in
contact with a steam cylinder mounted between said guide or tension rollers. The
second endless cloth does not encircle the large cylinder, but is guided by suitably
arranged guide and tension roller in such a manner that it closely enfolds face to
face approximately the whole of that part of the first endless cloth in contact with
the large cylinder. A heating cylinder is also provided to heat the face of the
second cloth.
The several parts of the above mentioned apparatus are so relatively arranged that
when the endless cloths, cylinders and minor parts are put into operation the fabric to
be pressed is fed in between the heated faces of the cloths and is thus exposed to the
pressure between them as they travel round the greater part of the periphery of the
large cylinder. The said pressure is regulated by the tension of the endless cloths.
Reference is to be had to the accompanying sheet of drawings in which similar
letters of reference indicate corresponding parts in each of the figures.
Figure 1, represents a side elevation of my improved apparatus with the nearer
side frame removed and the cross stay of the framework omitted.
Figure 2, is a plan view of the same.
The side frames A, A are braced together in any ordinary manner and are provided
with bearing a in which the shaft b of the large cylinder B is mounted. The inner
endless cloth C is placed round such cylinder and is also passed between the rollers D
and Dover the adjustable tension roller G,under the guide roller E,round the heating
cylinder F, and down between the nip rollers H, H and then again comes in contact
with the large cylinder B. The outer endless cloth C' enfolds the cylinder B and
that portion of the inner cloth in contact therewith but after passing between the
rollers D and D' it is passed round the roller D so as to fold back over itself, under
and over the guide rollers E¹ and E2 beneath E and E, up over the adjustable tension
roller G then round the heating cylinder F¹ and between the nip rollers H, H.
The apparatus is conveniently used in conjunction with an Elder's rigging
machine" and the rollers II, II represent the nip rollers of such a rigging machine
But in this case they may be simply driven by the said endless cloths passing
between them. The endless cloths are driven at the same speed by the nip
rollers D and D¹ between which they are passed, and the outer cloth is guided
almost completely round the larger roller D so as to increase its hold of the cloth.
The roller D is driven by belting by means of the pulley J mounted upon its shaft.
Other methods of driving the endless cloths may be employed or in addition to
the above, and the rollers D and D' may be made of equal size and geared
together.
In operation the fabric either "rigged" or single-width is fed in between the
heated faces of the endless cloths as they pass between the rollers H, H and is
exposed to more or less pressure according to the tension of the cloths as such
cloths carrying the fabric with them pass round the cylinder B. I may use pressure
rollers to directly press the endless cloths against the cylinder. The fabric leaves
the apparatus in a finished condition when it reaches the rollers D and D' and may
then be passed to a folding or plaiting machine arranged in conjunction with the
apparatus.
The copper cylinders F and F are heated by steam in the ordinary way and it
will be noticed that they heat the faces of the cloths immediately before such faces
come in contact with the fabric. The cylinder B may also be heated by steam.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare what I
claim is
1. Finishing or pressing apparatus consisting of two endless cloths placed face to
face and mounted around a cylinder under tension in such a manner that one

page_text: enfolds a portion of the other and that a fabric may be passed between them to be
pressed or finished, substantially as herein shown and described.
2. The combination with the apparatus embodied in the previous claim of heating
cylinders or their equivalent arranged to heat those faces of the endless cloths which
come in contact with the fabric, substantially as herein shown and described.
