PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus for Pressing and Tentering
Woollen and other Woven or Felted Fabrics.
We, GEORGE HENRY NUSSEY of Boar Lane, Woollen Manufacturer, and WILLIAM
BRADSHAW LEACHMAN of Great Wilson Street, Mechanical Engineer, both of Leeds
in the County of York, do hereby declare the nature of this invention to be as
follows:-
Our improvements have reference to machinery or apparatus for pressing and
tentering woollen and other woven or felted fabrics; and for the above purpose we
mount between suitable framework a roller, being fittod so as to revolve freely in such
framework. Below this roller is provided an expanding table or plate, such plate
being of the same or nearly the same circle as the roller. The periphery of the roller
and also the surface of the table or plate are brought to a smooth finished state, so
that the material (passing between them) after being pressed, presents a beautifully
smooth surface.
The material is drawn between the roller and plate by means of side chains, in a
similar manner to that described in our Patent No. 3450 dated 17th March 1885.
In order to suit the different widths of material, the plate is formed in two parts,
the inner edges fitting together in a diagonal line; so that by moving one part of the
table any suitable distance round the roller, the width of such plate is increased
or reduced at pleasure, at the same time the chains for carrying the cloth forward are
also moved outwards.
The table or plate is pressed up to the roller by hydraulic or other suitable means,
and the pressure thereof may be varied in accordance with the finish required on tho
material.

COMPLETE SPECIFICATION.
Improvements in Machinery or Apparatus for Pressing and Tentering
Woollen and other Woven or Felted Fabrics.
We, GEORGE HENRY NUSSEY of Boar Lane, Woollen Manufacturer, and WILLIAM
BRADSHAW LEACHMAN of Great Wilson Street, Mechanical Engineer, both of Leeds
in the County of York, 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 :-
:-
Our improvements have reference to machinery or apparatus for pressing and
tentering woollen and other woven or felted fabrics.
In the accompanying drawings
Fig. 1 is a side elevation. Fig. 2 an end elevation, and Fig. 3 a plan looking at
the top shewing general construction of machine. Figs. 4 and 5 are respectively an
end and longitudinal elevation of roller. Fig. 6 is a transverse section.. Fig. 7 is a
side elevation. Figure 8 is an end elevation, and Figure 9 is a plan looking at the top
of rising table.
For the above purpose we mount between suitable framework A in bearings B a
hollow roller C, such roller being fitted so as to revolve freely in such framework.
Below this roller is provided a hollow rising table or plate D, a portion of which
at E can be moved round in a diagonal direction, so that the table can thereby be
increased or reduced in width to suit the width of material to be operated upon.

page_text: The table or plate may be heated from any convenient source.
The loose portion E
of the table or plate D is moved round and adjusted in position by the attendant
through hand wheel F, shaft G, rack pinion J, and rack H.
The inner face of the loose piece E and that of the plate D proper, are of a screw or
spiral form, so that on the loose piece being moved round through the medium of the
rack pinion J and oblique rack Hit not only has a circular but also an outward
movement imparted thereto widening thereby the base on which the material is pressed
by the roller,
The rack pinion J revolves with its shaft and thereby actuates or moves round the
spiral rack E provided in the loose portion E of the plate D; in so doing the loose
piece moves outwards at an angle corresponding with the angle of the rack, consequently
the rack pinion is in gear with the rack continually.
The periphery of the roller and the surface of the table or plate D are brought to
a sunooth finished state so that the material passing between them, after being pressed
presents a beautifully smooth surface.
The material is drawn between the roller and plate by means of side chains K, in a
similar manner to that described in our Patent No. 3150 dated 17th March 1885, and
the width of such chains apart is or may be adjusted simultaneously with the adjust-
ment of the rising table or plate D, the required movement being effected through
screws Land M operated by hand wheel N, bevel wheels O, and diagonal shaft P.
The table or plate D is pressed up to the roller C by hydraulic pressure in a similar
manner to that described in our Patent No. 3450 aforesaid, except that the pressure is
retained upon the material whilst such inaterial is passing between the plate and
roller. The desired pressure may be obtained by other convenient means when.
preferred, and the pressure may be varied in accordance with the finish required on
the material. The cutling apparatus R is or may be of ordinary construction.
Motion is transmitted to the machine through suitable gearing S and driving
pulleys T.
The roller C is heated by steam or other means from any convenient source.
It is to be understood that we reserve to ourselves the right to vary the arrange-
ments employed in carrying out the above invention, which may be variously modified
without departing from the distinctive features thereof.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1st. The arrangement, construction and application of expanding rising table or
plate D, in combination with steam roller C, operating substantially as and for purposes
herein set forth.
2nd. The general arrangement, construction and combination of the various parts
forming the machine for pressing and tentering woollen and other woven or felted.
fabrics substantially as herein set forth.
