page_text: I, FREDERICK MILAN, of Hydro Works, Lockwood, Huddersfield, in the County
of York, Engineer, do hereby declare the nature of this invention to be as
follows -
This invention relates to mechanical washing machines such as are employed
in laundries for cleansing, washing, softening and disinfecting clothes and
goods
My improvements in said machine comprise firstly, an improved construction
of the rotary cage or cylinder in which the clothes or goods to be washed are
placed. I make the said cylinder of any suitable metal which 16 corrugated
longitudinally or similarly undulated or fluted all round In cross section of
the cylinder the convex portions of the corrugations are made plain but the
concave poitions of the corrugations are perforated or provided with suitable
openings
As the cylinder revolves in the washing machine a quantity of water 18 lifted
up by the corrugations to or near to the top of the cylinder when it falls through
the perforations and is showered down in finely divided streams on to the clothes
or goods inside the cage or cylinder, thus agitating and keeping up a constant
shower of water which materially assists in cleansing the goods and shortens the
process The plain or unperforated portions of the corrugations are the only
surfaces brought into contact with the clothes or goods and consequently they
in no wise injure said clothes as is the case when a perforated cylinder is em-
ployed as at present The cylinder is provided with a sliding or hinged door
for the introduction and withdrawal of the clothes or goods For the purpose of
steaming or disinfecting I make the shaft at one side of the cylinder hollow or
with an opening therethrough which has communication at its outer end with a
steam supply pipe through which steam is admitted to the shaft and issues from
thence through a perforated or openwork mouthpiece or cap into the centre of
the cylinder at one side thereof, the steam serving to disinfect or destroy all
germs in the clothes or goods The end of the said hollow shaft is jouinalled
in a suitable gland which can be loosened and reversed as required to change
the bearing surface when woin and piesent a fresh bearing surface for the
shaft.
The cage or cylinder may be rotated by any ordinary arrangement of change
driving mechanism but preferably I prefer to employ one driving pulley only
and change or reverse the motion of the cylinder by means of mitres or equivalent

I, FREDERICK MILAN, of Hydro Works, Lockwood, Huddersfield, in the County
of York, Engineer, do hereby declare the nature of this invention and in what
manner the same 18 to be performed, to be particularly described and ascer
tained in and by the following statement:-
This invention relates to mechanical washing machines such as are employed
in laundries for cleansing, washing, softening, and disinfecting clothes and goods
My improvements in said machines comprise an improved construction of the
1otary cage or cylinder m which the clothes on goods to be washed are placed
I make the said cage of any suitable metal which is corrugated longitudinally
or similarly undulated or fluted all 1ound In cross section of the cage o
cylinder, the convex portions of the conugations or indentations are made
plain, but the concave portions of the coniugations are perforated or provided
with suitable openings
As the cage or cylinder revolves in the washing
machine, a quantity of water is lifted up by the corrugations to or near to the
top of the cylinder when it falls through the perforations and 18 showered down
in finely divided streams on to the clothes or goods inside the cage or cylinder,
thus agitating and keeping up a constant shower of water which matenally
assists in cleansing the goods and shortens the process The plain or unpel-
forated parts of the coniugations are the only surfaces brought into contact
with the clothes or goods and consequently they in no wise injure said clothes as
is the case when a plain perforated cylinder 18 employed as at present The
evlinder is provided with a sliding or hinged door for the introduction and with-
drawal of the clothes
For the purpose of steaming or disinfecting I make the shaft at one side of the
cylinder hollow or with an opening ther ethiough which has communication at
its outer end with a steam supply pipe through which steam is admitted to the
shaft and issues from thence through a perforated or openwork mouthpiece or
cap into the centre of the cylinder at one side thereof, the steam serving to dis-
infect, or destroy all germs in the clothes or goods. The end of the hollow shaft
18 Journalled in a suitable gland which can be loosened and turned round cir-
cumferentially a thud or more to change the bearing surface when worn and
present a fresh bearing surface for the shaft
In order that my said invention may be fully understood reference is herein-
after had to the annexed sheet of diawings, forming a part of this specification
in which,
Fig. 1 is transverse section of so much of a mechanical power washing
machine for laundries as is essential to shew my improvements, and
Fig. 2 18 longitudinal elevation of the machine partly in section
Refering to the diawings letter A represents the enclosing casing or shell
of the machine, and B the 1otary cage or cylinder supported centrally therein
into which the clothes on goods to be washed or cleansed are placed. The outer
casing or shell A 18 provided as ordinarily with an opening A¹ for giving access
to the cage and with a door (not shewn) for closing sand opening My improve-

page_text: ments in this class of machine relate to the rotary cage or cylinder B and con-
sist in corrugating the metal walls or surface of same longitudinally or otherwise
undulating or fluting the metal all round, and in perforating the outer curving,
undulated, or fluted portions thereof, that is to say,-in closs section of the cage
or cylinder, the convex portions B' of the corrugations are whole or plain while
the concave portions B are perforated or pierced with numerous holes. The
cage B is provided with a sliding door to admit of the clothes or goods being
passed into or withdrawn from the cage through the opening D and which seals
up the cage during the washing process, such door also being made of corrugated
metal perforated in the outwardly curved portions of said coniugations
By constructing the rotary cage or cylinder B of corrugated or fluted metal
and perforating the outwardly curved or arched portions of such corrugations
or flutes in the manner shewn and described, each plain corrugated portion B',
as the cage revolves in the machine, lifts up a quantity of water which is carried
thereby forward towards the top of the cylinder for a short distance when it flows
over the perforated portions B2 and falling through the openings therein is
showered down in finely divided streams on to the clothes or goods within the
cage, thus agitating and keeping up a constant shower of water which materially
assists in cleansing the clothes and shortens the washing on cleansing process
An additional advantage is gained in the above construction of rotary cage or
cylinder in that the surface contact of said cage 18 considerably reduced the
plain or unperforated portions B of the corrugations being the only surfaces
brought into contact with the clothes or goods As a consequence of this the
clothes are in no wise injured or damaged in washing as is the case with the
plain perforated cages at present employed. The corrugating of the cage or
cylinder greatly increases its strength
The cage B is provided as usual, with mid-feathers or radial divisions E for
agitating the clothes and preventing them from rolling
For the purpose of steaming or disinfecting the clothes or goods in the cage,
I make the shatt Fat one side of the cylinder hollow or with an opening Fi
therethrough which has communication at its outer end with a steam supply
pipe G through which steam is admitted to the shaft and issues from thence
through a perforated or openwork mouthpiece or cap into the centre of the
cage or cylinder at one side thereof, the steam serving to disinfect or destroy
all germs in the clothes or goods contained therein The end of the shaft F 18
journaled in a gland I which can be loosened and turned upon the axis F to
change the beating surface when won, and present a fresh bearing surface for
tho shaft.
The cylinder or cage may be rotated by any ordinary arrangement of change
diving mechanism but, by preference I employ one having pulley only, with
a single diving stiap, and change or reverse the motion of the cylinder by means
of mitres or equivalent toothed wheels which are placed into and out of gea
alternately by sliding clutches actuated by rod or lever
I would have it understood that I do not confine myself to the precise arrange-
ment and form of configuration of the corrugations or flutes as these may be
vaned as desued without departing from the main features of my invention
Having now particularly described and ascertamed the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is,
-
(1) In mechanical washing machines, a rotary internal cage or cylinder having
its walls, shell, or surface coniugated or otherwise suitably undnlated or fluted,
and the outwardly arched on cuising portions of said corrugations perforated
o pierced with numerous holes, in the manner and for the purposes substan-
tally as heien shewn and described
(2) In mechanical washing machines, the combination of a corrugated internal
cage oi cylinder having the outwardly curving portions of the corrugations per-

page_text: forated or pierced with holes, a hollow axis for admitting steam to the cage, an
adjustable gland forming the bearing for said axis, and a perforated central cap
or hood through which the steam enters and 18 distributed within the cage sub-
stantially as set forth.
