I SAMUEL HARDLEY of East Street, Ashburton Canterbury, New Zealand, Tinsmith,
do hereby declare the nature of my invention and in what manner the same is to
he performed, to be particularly described and ascertained in and by the following
statement:-
The machine as constructed by me consists of two Sheet metal drums inner and
outer, one (the outer) being practically a casing within which the other may revolve,
both or either may be made of Galvanized Iron Tin or Copper:-As more particularly
shewn on the drawings herewith, they are hung or journalled on an Iron frame in
such a manner that the inner drum may be revolved either in connexion with or
independently of the outer drum or casing which (the latter) when the machine is in
operation, i.e. the inner drum revolving, is secured from movement by bolting to the
frame: this outer casing is made in two parts, the upper portion serving as a
removable cover. One of the axles which is rigidly secured to the outer drum but on
which the inner drum revolves, is an 1 Inch Pipe which serves to convey the steam
from an auxiliary boiler or other steam generator direct into the interior of the inner
drum, and is also perforated with four holes so that a portion of the steam may escape
into the space between the two drums, being thence drawn into the interior of the
inner drum by its revolution through orifices made in one of its sides, as well as
through or by the perforated beaters or corrugations constructed in its periphery.
When the machine is to be used, the outer casing is bolted to the frame, and the
cover removed, a portion of the periphery of the inner drum constructed so as to slide
backwards and forwards within grooves fixed on the side of the drum, and hereafter
called the sliding door is pushed back, and the articles to be washed placed in the
inner drum and a necessary (not a large) quantity of boiling water and sliced soap
added.
The pipe axle before starting is connected with the Portable or fixed boiler or any
steam generator, the sliding door is put back in its place and bolted, and the cover
replaced on the outer casing. The inner drum is then revolved by turning the handle,
the outer casing being stationary, the direction of revolution being that the perforated
surface of the corrugations or beaters of the inner drum should be the opposing
faces.

The time necessary for ordinary soiled linen is about ten minutes, but when the
articles are considered to be sufficiently cleansed, the cover of outer casing is removed
the inner drum opened by pushing back the sliding door in the grooves and fastening
by bolting it, the outer casing is then secured to the inner drum by a latch, and
unbolted from the frame; by reversing the handle, the whole is revolved so as to
empty the contents of both the drums into a tub or other convenient receptacle, which
can be at once removed, and the machine is ready without any loss of time for another
and immediate operation.
Referring to the drawings herewith-
The same letters refer to corresponding portions of the machine in the different
diagrams.
Sheet 1 Fig. 1 is a sido elevation of the machine with the cover removed. A is the
outer drum or casing, B the cover of same, the inner drum, D the frame E the
handle for revolving the drums, F the vessel for reception of the washed clothes &tc.
G the latch for securing the two drums together.
Fig. 2 is an end clevation, also with the cover removed and with sliding door of
inner drum opened, shewing interior of inner drum with the corrugations or beaters,
and perforations therein, H. is the bolt fastening the outer casing to the frame, I. the
corrugations with the orifices for entry of steam, M the bolt for securing the sliding
door when closed, K the steam pipe for conveying steam to interior of drums.
Fig. 3 is an elevation of side of outer casing shewing steam pipe K and
Fig. 4 shews the drums with the cover removed in the position of emptying.
Sheet 2, Fig. 5 is a transverse section of both drums shewing details of construction
more distinctly. The sliding door is supposed to be open, so as to shew one of tho
securing bolts. L is the sliding door, M the bolt to same, N orifices in the corru-
gations, O the holes in the Steam pipe to admit steam between the two drums, P. holes
in the side of inner drum.
Fig. 6 is a longitudinal section of inner drum, showing the sliding door closed, its
position when opened is indicated by the dotted lines S. It carries a bolt at each end,
and the letters Q and R respectively denote the places where the door is bolted when
closed or open.
The principles and details of construction that I claim as new and as grounds for
protection by letters patent are―
1. The manner of using and circulating steam in the operation of washing by
(a) the direct admission into the inner drum through the hollow axle or steam pipe K.
and (b) the indirect admission or circulation of the steam by the several orifices O in
steam pipe N in the corrugations or beaters and P in side of drum, whereby in
connection with the continued agitation causing by the revolving of the inner drum,
. the articles to be washed are brought into complete and intimate contact with the
steam, and an effectual result produced.
2. The principle on which the drums are expeditiously emptied which obviates the
necessity of handling the hot and wet clothes and other articles this being done
automatically also the constructive means by which it is effected, namely, the bolt H.
the latch G and the sliding door L.
3. The general arrangement and adaptation of the several members or portions of
the machine which to the best of my knowledge and belief is novel and my invention.
