We GEORGE HENRY NUSSEY of Boar Lane Woollen Manufacturer and WILLIAM
BRADSHAW LEACHMAN of Tonbridge 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 invention refers to improvements in machinery or apparatus for pressing
woollen and other woven or felted fabrics, for which Letters Patent were granted
to us dated 26th January 1876 No 242 and No 3450 dated 17th March 1885.
The object of our present invention is to provide an arrangement whereby two
or more pieces may be operated upon at the same time, thereby considerably
increasing the amount of work done and without greatly increasing the expense of
the machine.
DESCRIPTION OF DRAWINGS.
Fig. 1. is a front elevation and Fig. 2 a side elevation shewing general
arrangement of machine with our improvements applied.
Fig. 3. is a front elevation and Fig. 4 a side elevation shewing a modification of
the movement of table and plate.
At Figs. 1 and 2 a is the framework of the machine.
We employ a table b raised by steam or hydraulic pressure, such pressure being
brought to bear upon a ram c within the cylinder d.
e is the top plate which is fixed to the framework a of the machine in the
ordinary way. Between the top plate e and the bottom plate b we apply an
intermediate plate f of convenient thickness; this plate fis fitted between the
framework a so as to be capable of a vertical sliding movement.
Between the top side of this plate f and the underside of the top plate e press
papers or plates g are suspended, similar to those described in the hereinbefore
mentioned Specifications.
Between the upper side of the bottom plate b and the lower side of the
intermediate plate f press papers or plates g are also employed as above described.
The direction of movement of the material h being operated upon, is shewn by
arrows, such material being conducted from the machine by their respective
conducting rollers i and j for the cutling operation.
The lower plate being caused to rise carries up with it the material that is
passed round the press papers or plates g between it and the underside of the
intermediate plate f, then continuing its course lifting the intermediate plate f and
with it the material that is passed round the press papers or plates g between it
and the underside of the top plate e. The whole is then moved upwards against
the underside of the top plate e and the desired pressure put upon the material,

page_text: after which the pressure is removed and the material h and the intermediate
plate freturn to their original positions as shewn in the drawings; this being done
the pressed material is drawn forward and a fresh supply passed between, and the
operation continued.
The means employed for bringing into operation the lower plate b, also
the arrangements for imparting motion to the various parts and arresting the.
same, are the same as those described in the Specification of our patent dated
17th March 1885 No 3450.
The intermediate plate f may be constructed in the same manner and be capable
of expansion and contraction to suit the various widths of material as that
described in the hereinbefore mentioned patent.
At Figs. 3 and 4 we employ a bottom table or plate 1 and a top plate 2, both of
which are firmly attached to the framework 3 of the machine, and provide
between them an intermediate plate 4 which has a vertical movement and through
which the pressure required for the pressing operation is imparted.
Between it and the upper plate 2, and also the lower plate 1 press papers or
plates 5 are suspended in a similar manner to the hereinbefore described, also the
material 6 to be operated upon is passed round such press papers or plates 5 as
herein before described and shewn by arrows and then conducted away over their
respective conducting rollers 7 and 8.
In this arrangement we move the intermediate plate 4 alternately up and down
pressing the material between it and the top plate 2 in its upward movement and
afterwards pressing the material between it and the bottom plate 1 in its downward
movement.
As soon as the pressure is taken off the material between the intermediate plate 4
and the top plate 2 is fed forward and new material passed round the press papers
or plates 5 ready for another operation.
The same movement takes place when the material is relieved from the top side
of the bottom plate 1 and the underside of the intermediate plate 4.
The required movement and pressure is imparted to the intermediate plate 4
from a steam or hydraulic cylinder 9 through piston 10 piston rod 11, cross
head 12, connecting rod 13 and studs or bosses 14.
The means employed for bringing into operation the intermediato plate 4 also
the arrangements for imparting movement to the various parts, and arresting the
motion of the same, are the same as those described in the Specification of our
patent dated 17th March 1885 No 3450.
Other parts of the machine not described may be of the same construction as
those employed and described in the Specification of the herein before mentioned
patents.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
The arrangements and application of intermediate plate fin combination with
the lower table or plate 6 and top plate e and the means employed for actuating
the same as shewn at Figs. 1 and 2 and modifications of the same as shewn at
Figs. 3 and 4, substantially as herein set forth for pressing woollen or other
woven or felted fabrics.
