Finisher, all in the County of Lancaster do hereby declare the nature of this
invention to be as follows:-
That at present india rubber or composition covered bowls cannot be used for
running in a box containing boiling starch or other hot liquids, as it causes the
covering to leave the metal body of bowl, we claim that by running cold water
through the centre of the spindle or shaft of bowl into the cavity, it will keep the
body and covering cool, so that the heat from the boiling starch or hot liquids will
have no detremental effect on the india rubber or composition covering of the
bowls, and by useing this bowl in the starching or finishing of printed fabrics it will
not damage the colourings or woven objects, as is the case with the present system
of useing brass, wood or cotton bowls.

COMPLETE SPECIFICATION.
An Improvement in Bowls for Finishing Textile Fabrics.
We, WALTER THOм, of Birkacre, Chorley, in the County of Lancaster, Calico
Printer, JAMES WALLWORK, of Birkacre aforesaid, Engineer, and ĆEPHAS
HIGGINBOTTOM, of 18 Pall Mall, Chorley aforesaid, Print 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:-
Our invention relates to an improvement in bowls for finishing textile fabrics,
and the chief object of our invention is to enable india rubber or composition
covered bowls to be used in place of the ordinary metal or wood bowls hitherto
employed in the process of finishing textile fabrics for running in boxes containing
boiling starch or other hot liquids.
To accomplish this object we construct our improved bowl in a suitable manner
hereinafter described and illustrated and run cold water through it so as to keep
the body cool and preserve the india rubber or composition covering from injury
from the boiling starch or other hot liquid in which it is running.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Fig. 1 is an elevation of our improved bowl or roller employed in starching or
finishing machines and Fig. 2 is a longitudinal section of the same.
In these views,-
-a is the shaft or axle of the bowl or roller to which is secured a
metal shell b, this shell is ordinarily covered with brass. There are, however,
several objections to such metal bowls and to obviate these objections the bowls
have been covered with rubber, or composition of rubber and other substances;
but the heat to which they are subjected when working in vessels filled with boiling
Prinn 27

page_text: starch and other liquids in a short time acts upon the cement by which the rubber
is secured to the bowl and softens and then loosens the covering which quickly
comes off and the bowl is then rendered useless.
According to our invention we are enabled to utilize metal bowls covered with
rubber or composition in the boxes filled with boiling starch or other liquids by
circulating cold water through the hollow bowls.
A convenient mode of effecting this is as follows:-
The axle is bored for a distance up each 'end at a', and at the inner ends these
holes are connected by transverse holes a², with the inside of the bowl. To each
end of the axle a, is secured a small pipe c, the joints of which are made with a
stuffing box or gland d, or in any convenient manner. A continuous supply of
cold water is conveyed to the bowl through one pipe c, and enters it through the
holes a², and thence escapes through the holes a², and pipe c, at the other end,
the quantity of water circulating through the bowl being governed by a valve,
not shown.
By means of this circulation of cold water in the shell, the bowl is kept cool and
the cement by which the rubber or composition covering is secured to the bowl is
thus prevented from being softened or injuriously affected by the heat of the
starching or other liquid in which the bowl is partially submerged and we are
thereby enabled to dispense with the use of metal covered or wooden bowls for
working in the boiling starch or other hot liquids, which are liable to damage the
printed surface of the printed fabrics (prints) in passing through the finishing
processes and in their place employ a rubber covered lower bowl in combination
with an upper bowl of wood or metal as usual for squeezing the starch or other
liquid out of the fabric and thus obtain all the advantages which rubber covered
bowls possess for the operations of starching and finishing printed fabrics.
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 improved bowl which consists in its essential features of a hollow metal
shell, a rubber or composition covering, and means for circulating cold water
through said shell all substantially as herein set forth.
