COMPLETE SPECIFICATION.
Improvements in and appertaining to Dolly Tubs, Dyeing Vats,
and the like.
We JOHN HANNAH GOLD of 117 Shakespear Street Southport and GEORGE
JOSEPH BOWCOCк of 127 Duke Street Southport, both in the County of
Lancaster, Ironmongers Assistant and Gentleman respectively 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 has for its object improvements in dolly tubs or similar receptacles
for use in washing clothes &c. It may also be applied to vessels wherein fabrics
are treated with a liquid for other purposes than washing, such as dyeing.
We will first describe a domestic dolly tub constructed according to our
invention.
It consists of an outer tub of wood, metal or other suitable material, & is
preferably of the usual shape & dimensions.
Inside this tub is a cylindrical lining of crimped fluted or corrugated metal
preferably zinc.
The crimps or ridges may be of about one inch in depth and preferably extend
from top to bottom of the tub.
The crimped lining may either be fixed, or removable for cleaning &c. In some
cases the crimps may be deepest near the bottom of the tub where in use the
clothes &c. naturally gravitate & may decrease in depth towards the top; or if
desired the metal lining may terminate some distance short of the top of the tub.
A dolly tub constructed in accordance with our invention is-much more effectual
in use than an ordinary one.
The fabrics being dollied backwards & forwards (in the usual manner) impinge
and rub against the projecting edges of the dining and are in consequence more
easily & thoroughly cleaned than if they simply revolved in contact with a plain
surface.
The edges of the ridges may if desired be perforated at intervals in a manner
similar to the well known "washing board."
If the lining is removably placed in the tub we prefer to provide suitable handles
(such as of wire) to facilitate its withdrawal.
We find in practice that it is unnecessary to fasten the lining in place when
using a wood outer tub as the friction between the two prevents much movement,
but where the outer vessel is of metal, studs or similar devices may be employed to
effect this purpose.
Instead of employing a lining the outer vessel itself may be crimped if of metal
or separate ridges of a similar external form may be fastened in place inside &
these may be of wood or metal.
The invention is also applicable to vessels used in steam laundries.
Having now particularly described & ascertained the nature of our said inven-
tion & in what manner the same is to be performed we declare that what we
claim is.
1. A dolly tub or similar vessel the sides of which are provided internally with
crimps or sharp ridges substantially as described.

page_text: 2. A detachable lining for dolly tubs or the like which consists of metal such as
zinc or other suitable material crimped or otherwise sharply corrugated for the
whole or a portion of its depth, substantially as described.
3. The improved dolly tub taken as a whole substantially as described and for
the purposes specified.
