PROVISIONAL SPECIFICATION.
A New or Improved Hydro Extractor.
JOHN EDWIN TOLSON GEORGE TOLSON 38 Hartley Street Dewsbury Yorks
Engineers do hereby declare the nature of this invention to be as follows:-
This invention is in relation to a new or improved automatical hydro extractor
and consists of a new or improved shape of cage basket or cylinder which contains
the material to be operated upon, and is cone or taper shaped so that when in mortion
the material may be put in at one end it will gradually or automaticaly empty its self
at the other end by centre force after the material has been operated upon.
This cage basket or cylinder may be run horizontal or vertical or other wise.
Dated this 24th day of March 1894.
We, JOHN EDWIN TOLSON and GEORGE TOLSON, of 38 Hartley Street,
Dewsbury, in the County of York, Engineers, 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 relates to hydro extractors for drying fibrous or other materials,
and our improvements therein consist in making the cage, basket or cylinder conicaĺ
or taper so that on feeding the materials into the smaller end of the revolving cage
the fabrics or materials will be delivered automatically at the larger end of the said
cage whereby the process of drying by centrifugal force is continuous.
Such being the nature and object of our invention we will now proceed to describe
the same more fully, and for that purpose make reference to the accompanying
sheet of drawings, wherein Fig. is sectional elevation of one form of hydro
extractor constructed according to our invention.
A represents a conical or taper perforated cage or cylinder, such said cage being
driven by strap B and to lessen the power required to drive the said cylinder the
flauges Crest upon wheels or rollers D by which means the cylinder is supported
and revolves freely on the said pulleys. The rags or materials to be dried are fed
into the hopper E and after being carried around and dried they roll out at the
opposite end as indicated in the drawings. The cylinder A is perforated and as it
revolves at a great velocity the moisture or water in the rags or other materials
escapes through the said perforations, a cylinder F being employed to prevent the
water flying about the room.
A suitable form of trough may be employed at the bottom of the said cylinder or
casing F to collect the water which afterwards is run off by suitable form of outlet
pipe, but this forms no part of our invention.
Instead of mounting the conical revolving cage in a horizontal position as shewn
in Fig. 1 the conical cage may be mounted and revolved upon a vertical spindle G
shewn in Fig. 2.

page_text: In this case the materials are dropped into the centre of the cage A and by
the centrifugal action of the said cage, the fabrics rise up and are thrown over
the larger end of the said cage as shewn in the drawings, a casing F being employed
to prevent the materials flying about which would happen without the said casing.
In Fig. 3 we have shewn the conical cage A to be placed in a horizontal position
and driven by strap from pulley G. In this case we feed the materials through
hopper E to the smaller end of the cylinder and as the cage revolves the materials
fall out of the larger end thereof but in all the three cases illustrated, the process
of drying is continuous as whilst the machine is being fed it is also emptying itself
at the same ratio, and this process of feeding and emptying goes on whilst the
cylinder is revolving.
By the employment of a conical revolving perforated cage operating in the
manner herein shewn and described a much larger quantity of materials can be
dried than with the present construction of machine and this arises in consequence
of the machine not having to be stopped for the purpose of being emptied and
re-filled.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
:-
In a hydro extractor the use therein of a conical or taper revolving perforated
cage where the materials to be dried are fed in at the smaller end of the cage and
delivered at the larger end thereof, operating in the manner substantially as herein
described and shewn in the drawings.
