PROVISIONAL SPECIFICATION.
Improvements in Rollers for Dyeing and Bleaching Apparatus.
I, HARRY DUCKWORTH HALSTEAD of Crow Oaks, Whitefield, in the County of
Lancaster, Dyer, do hereby declare the nature of this invention to be as follows:-
In dye and bleach works, it is a matter of considerable difficulty to preserve the
state of the wooden rollers commonly employed, owing to the nature of their
material. In dyeing especially, when changing from one colour or shade to another,
it is almost impossible to so thoroughly remove every trace of the former colour that
there shall be no risk of its coming up in the roller and interfering with the
later. To avoid these defects, I construct such rollers in the following manner :-
A shell, having the length and diameter of the required roller, is constructed of
earthenware, stoneware, or porcelain, and is externally glazed during the process of
manufacture. In the centre of this shell the roller spindle is wedged, or is fixed
by running in melted sulphur or lead, or by analogous means. The shell should
have such a thickness as will prevent risk of accidental breakage.
In rollers of small diameter, where the provision of an axial hole for the
spindle might cause the shell to be too weak, and in other cases, I may make
the roller solid, and may form upon its ends concentric projections or recesses to
which gudgeons or the like may be connected.

Improvements in Rollers for Dyeing and Bleaching Apparatus.
1, HARRY DUCKWORTH HALSTEAD, of Crow Oaks, Whitefield, in the County of
Lancaster, Dyer, 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 rollers which are to be used in place of the ordinary
wooden rollers employed in dyeing and similar machines or upon or over which dyed
or bleached cloth passes or is wound, and its object is to so construct such rollers that
they will not deteriorate or decay and so that they may be easily and thoroughly
cleansed.
In the wooden rollers now commonly employed, for example in dyeing, it is almost
impossible to so thoroughly remove all trace of any colour with which they may be
coated or impregnated from one operation, as to prevent such colour coming up and
staining any cloth which may be passed over it dyed with another colour.
A roller constructed according to this invention consists of a shell of earthenware,
stoneware, porcelain, glass or the like, which in the case of earthenware or similar
D

page_text: materials may be glazed externally in the course of manufacture. In another form
the roller may be solid instead of being a shell and its ends may be mounted in
suitable caps. The shell roller is mounted upon a shaft or the like, or may be
otherwise mounted so as to be adapted to rotate. For example, the shell may contain
a central spindle which may be fixed by nuts screwing upon the spindle, or by means
of wedges or the like, or by running in melted lead or sulphur, or by analogous
The shell should have such a thickness as will prevent risk of accidental
breakage.
In order that my invention may be more readily understood I have hereto
appended a sheet of drawings which illustrate in what manner my invention may
be carried into effect.
Figure 1 illustrates partly in section and partly in elevation one form of improved
roller consisting of a shell mounted upon a central shaft.
Figure 2 similarly illustrates a form which may conveniently be adopted for
rollers of small diameters which would be unduly weakened by providing them with
an axial hole for a spindle.
Referring to Figure 1, A is a roller consisting of a shell of earthenware,
porcelain, glass, or the like mounted upon a central shaft B with which it can rotate.
The shaft and the shell may be secured together by lead or sulphur which may be
-melted and poured in to fill the space between the two as indicated at C. An
additional security may be afforded by the end plates or discs D which slide upon but
cannot rotate upon the shaft and are forced against the ends of the shell by the
The discs are preferably provided with projections to engage with the
substance of the roller."
As shown in Figure 2 a solid roller A may be employed with its ends formed to
engage with caps or the like F which are furnished with shafts or pivots G upon
which the complete roller rotates. The caps and the roller may be secured together
by screws or the like.
It will of course be understood that any convenient methods of mounting the rollers
may be employed in substitution for those described and illustrated, and that the
forms shown are only types of rollers constructed to embody my improvements.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Earthenware, porcelain, glass and similar rollers for use in dyeing, bleaching and
the like apparatus, constructed and arranged substantially as and for the purpose
hereinbefore described and as illustrated by the accompanying drawings.
