We; CHARLES LOXTON JACKSON,, M.I.C.E.,. of Wharfi Foundry,. Bolton, in the
County of Lancaster,, and! EDWARD: HORNBY, of Doffcocker, Bolton aforesaid; Fore--
man. Draughtsman;, do hereby declare the nature of this Invention to be as-
follows:-
Our invention relates to improvements in. the manufacture of bowls employed:
in calendering and otherwise treating textilé fabrics. and' other fabrics or materials
such as-paper.
Bowls for these purposes made of wood' possess many advantages but their want
of durability is such that a substitute for wood' is usually employed as for instance
discs of paper or. shavings liave long been employed in the manufacture of bowls.
The object. of our improvements is to obtain as good, or a better surface than
can be obtained by the use of discs of paper or shavings and at a reduced cost.
In carrying our improvements into effect we employ wood pulp, in the form of
sheets such as are imported into or made in this country to be subsequently.
manufactured into paper; these sheets of wood pulp are cut up into discs of suitable.
size and are then threadedi on to an axle when they are put under great pressure
to form: a: bowl:.
As an alternative we propose to take wood pulp in its pulpy condition and mould
it under pressure into discs of suitable size and thickness and then thread these
discs on to an axle prior to pressing, and forming them into a bowl.

Improvements in the Manufacture of Bowls Employed in Calendering
and otherwise Treating Textiles and other Fabrics or Materials.
We, CHARLES LOXTON JACKSON M.I.C.E., of Wharf Foundry, Bolton, in the
County of Lancaster, and EDWARD HORNBY, of Doffcocker, Bolton aforesaid, Fore-
man Draughtsman, 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 relates to improvements in the manufacture of bowls employed in
calendering and otherwise treating textile fabrics, and other fabrics or materials
such as paper.
Bowls for these purposes made of wood possess many advantages but the want

page_text: of durability is such that a substitute for wood is usually employed as for instance
discs of paper or shavings have long been employed for the, manufacture of bowls.
The object of our improvements is to obtain as good, or a better surface than can
be obtained by the use of discs of paper or shavings and at a reduced cost.
In carrying our improvements into effect we employ wood pulp, in the form of
sheets such as are imported into or made in this country to be subsequently manu-
factured into paper; these sheets of wood pulp are cut up into discs of suitable
size and are then threaded on to an axle when they are put under great pressure
to form a bowl.
:
As an alternative we propose to take wood pulp in its pulpy condition and mould
it under pressure into discs of suitable size and thickness and then thread these
discs on to an axle prior to pressing and forming them into a bowl.
In the accompanying Sheet of Drawings
Figures 1 and 2 are two sectional elevations of bowls made according to our
Improvements.
In these views, a designates the mandrel or axle of wrought iron, steel, or other
suitable metal, and b the wood pulp bowl which may either be composed of discs
stamped or cut out of sheets or moulded out of wood pulp. The wood pulp which
we employ is that prepared by what is known commercially as the sulphite process
as wood pulp prepared by the sulphate process is of too soft a character to resist
the great pressure to which it is subjected in the formation of the bowl and the
subsequent wear and tear. After the wood pulp discs have been threaded on the
mandrel a they are put under great pressure and so formed into a homogenous
bowl in the manner well understood in the manufacture of paper bowls.
The metal ends c are then slipped on to the mandrel a and are locked in position
as shown in Fig. 1, by placing the halves or segments of a metal ring d in each
groove a¹ and shrinking on a steel or wrought iron hoop e over each ring d; or
alternatively as shown in Fig. 2, the metal rings c are slightly conical internally
and a part of the mandrel a is also coned at each end and the locking segments
forming a ring d are driven in to fix the ends c.
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 herein described improvements in the manufacture of bowls employed in
calendering and otherwise treating textile fabrics, said improvements consisting
essentially in forming the surface of the bowl of a series of wood pulp discs
substantially as and for the purposes herein set forth.
