PROVISIONAL SPECIFICATION.
Improvements in Cleansing, Drying and Disinfecting Apparatus.
I, WALTER NOBLE TWELVETREES, of 265, Balham High Road, Upper Tooting,
in the County of Surrey, Engineer, do hereby declare the nature of this invention
to be as follows:
My invention relates to improvements in and connected with the cleansing, drying
and disinfecting of clothes and other fabrics or materials and has for chief objects
the construction of an apparatus in which centrifugal force and other means are
employed separately or in combination to attain the desired end.
In a machine constructed on the same principle as a centrifugal wringer that is
to say a cylinder with a rotating perforated cage therein, I introduce one or more
tubes having jets directed towards the material to be treated, through which I
introduce under pressure, hot or cold water, cleansing solutions, steam either satu-
rated or superheated, hot air and the like as required. The machine may be
steam-jacketted or otherwise so fitted that it can be heated either externally or
internally by suitable means and provided with apparatus for producing a partial
vacuum by exhaustion or condensation or both. The centrifugal force of the
machine is utilised either alone or combined with suitable circulating arrangements
for driving the water and cleansing solutions through the materials and boiling
may be effected by means of the steam jacket or by the introduction of steam,
in some cases the boiling process is preferably conducted in vacuo. The removal
of liquid and vapour is effected by means of centrifugal force aided by the use of
superheated steam, hot or cold air, by the establishment of a partial vacuum either
separately or in combination. Disinfection may be performed by means of satu-
rated steam under pressure before the process of drying is effected
described.
as above
For the centrifugal cleansing apparatus may be substituted the ordinary arrange-
ment in which the materials are cleansed by treatment in a rotating cage contained
in a cylinder and in cases where it is merely desired to dry or disinfect the material,
a hot chamber furnished with means of introducing steam hot air or both, and
fitted with apparatus for producing a partial vacuum as before described, will serve
the purpose.

I, WALTER NOBLE TWELVETREES, of 91, Louisville Road (late of 265, Balham
High Road), Upper Tooting, in the County of Surrey, Engineer, do hereby declare
[Price 8d.]

page_text: 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:-
My invention relates to improvements in and connected with the cleansing, drying
and disinfecting of clothes and other fabrics or materials and has for chief objects
the construction of an apparatus in which centrifugal force and other means are
employed separately or in combination to attain the desired end.
In a machine constructed on the same principle as a centrifugal wringer that is
to say a cylinder with a rotary perforated cage therein, I introduce one or more
tubes having jets directed towards the material to be treated through which I
introduce under pressure, hot or cold water, cleansing solutions, steam either satu-
rated or superheated, hot air and the like as required. The machine may be
steam-jacketted or otherwise so fitted that it can be heated either externally or
internally by suitablo means and provided with apparatus for producing a partial
vacuum by exhaustion or condensation or both. The centrifugal force of the
machine is utilised either alone or combined with suitable circulating arrangements
for driving the water and cleansing solutions through the materials and boiling
may be effected by means of the steam jacket or otherwise by the introduction of
The
steam. In some cases the boiling process is preferably conducted in vacuo.
removal of liquid and vapour is effected by means of centrifugal force aided by the
use of steam, hot or cold air, by the establishment of a partial vacuum either separ-
ately or in combination. Disinfection may be performed by means of saturated
steam under pressure before the process of drying is effected as above described.
For the centrifugal cleansing apparatus may be substituted the ordinary arrange-
ment in which the materials are cleansed by treatment in a rotating cage contained
in a cylinder and in cases where it is merely desired to dry or disinfect the material,
a hot chamber furnished with means for introducing steam, hot air or both
fitted with apparatus for producing a partial vacuum as before described, will serve
for the purpose.
Upon the accompanying sheet of drawings:-
Figure 1-Represents a vertical section through a centrifugal machine con-
structed in accordance with my invention.
Figure 2. Is a longitudinal section illustrating the application to a rotary
machine.
Figure 3. Being a transverse section through the same.
In the construction shewn in Figure 1 the operation is as follows. The material
to be treated having been placed within the busket A the latter is then caused to
revolve by means of the pulley secured to the lower end of the spindle B. Tepid
water is first introduced in the form of spray through the perforated pipe O so as
to impinge upon the material within the basket. A sufficient quantity of soap
solution is next introduced through pipe C and the whole gradually heated up by
means of the steam coil D or by the introduction of live steam through the perfor-
ated nozzle E. The solution thus heated is then caused to circulate for a time by
the pump F through the pipe G and perforated pipe C after which the soapy water
is drawn off through the cock H.
Clean water is next introduced through the perforated pipe C and raised to boiling
point (the rotation of the basket being continued or not as desired).
The material is then rinsed by causing the water to circulate through the pipe G
by means of the pump F, a solution of blue being added or not as required through
the pipe C. After this should the basket have been stopped, it is again set in
motion for the purpose of extracting the water from the material. As soon as this
is accomplished the waste cock II is closed, the coil D heated and if desired free
steam may be admitted through nozzle E until a pressure of about 15lbs. per square
inch is obtained. The free steam is shut off after sufficient exposure and the vapour
is allowed suddenly to escape through the pipe K, the operation being continued
after atmospheric pressure has been reached, by means of an ejector L or equivalent
device. This latter operation is repeated as often as may be found desirable after

page_text: which the material is dried by admitting air through the valve M to the coil D
and exhausting through the pipe as before.
In the arrangement shewn on Figures 2 and 3 the operation is carried out in a
precisely similar manner with the exception of the circulation of the water which
may, if desired, be omitted. Similar letters refer to the same, or to corresponding,
parts throughout the various sectional views.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. An apparatus for cleansing clothes, fabrics and the like characterised by the
rotation of an inner basket within a closed vessel, and by circulation within the
apparatus of the cleansing and other liquids, with or without a vacuum within the
interior of the apparatus, substantially as described.
2. An enclosed apparatus for drying clothes, fabrics and the like, by means of
the rotation of an inner basket aided by the use of hot air and, if desired, of a
partial vacuum and of free steam under pressure, substantially as described.
and
or
3. An enclosed apparatus for cleansing drying disinfecting clothes, fabrics
and the like, consisting of an inner rotatable basket arranged to be heated by steam
or hot air, inlet pipes for the admission, in the desired order, of hot, tepid and cold
water, and of means for exhausting such fluids, substantially as described.
and
ог
4. An apparatus for cleansing, drying- disinfecting clothes, fabrics and
the like, consisting of a basket A rotatable upon a shaft B, and within an outer
closed casing, of an inlet pipe C, of a steam coil D and of circulation pipes for the
water or other fluids, with means for drawing off or exhausting the latter when
desired, substantially as described.
5. Apparatus for cleansing, drying and disinfecting, constructed, combined, and
operating substantially as and for the purposes described, with reference to the
accompanying drawings.
