We, JOHN LAIDLAW of the Firm of Watson, Laidlaw & Co., of 98, Dundag
Street, South, in the County of the City of Glasgow, North Britain, and JAMES
WRIGHT MACFARLANE, Manager of the said firm, Engineers, do bereby declare
the nature of this invention to be as follows: --
This invention relates to improvements in centrifugal machines or hydro-
extractors, which are driven direct by water or other fluid turbine or motor fixed
upon the spindle of the basket or upon a ring attached to the underside of the
bottom of the basket and which is more particularly applicable to machines such as
are described in Patent No. 1950 A.D. 1896, granted to the said John Laidlaw
and Charles Alphonso Matthey.
In carrying out our invention the reservoir tank for holding the supply of
water and to which the water is returned after use, is formed in the lower part
of the outer casing of the extractor, and the steam or other pump for producing
the requisite pressure of water or other liquid, is fixed in any convenient manner
to the side of the easing in order to make the machine complete as a whole and
self-contained.
In such cases when it is desired that the pump should not be attached to the
casing of the machine, it may be removed to any convenient distance from the
machine and the necessary pipes led from the pump to the machine, but of
course retaining the special arrangement at the bottom of the extractor casing as
a supply or reservoir tank.

Improvements in Centrifugal Machines.
We, JOHN LAIDLAW, of the Firm of Watson, Laidlaw & Co., of 98, Dandas
Street, Sonth, in the County of the City of Glasgow, North Britain, and JAMES
WRIGHT MACFARLANE, Manager of the said firm, Engineers, do hereby declare
the vature 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 improvements in centrifugal machines or hydro-
extractors, which are driven direct by water or other fluid turbine or motor
fixed upon the spindle of the basket or upon a ring attached to the underside
of the bottom of the basket and which is more particularly applicable to machinos
such as are described in Patent No. 1950 A.D. 1896, granted to the said John
Laidlaw and Charles Alphonso Matthey.

page_text: In carrying out our invention the reservoir tank for holding the supply of water
and to which the water is returned after use, is formed in the lower part of the
outer casing of the extractor, and the steain or other pump for producing the
requisite pressure of water or other liquid, is fixed in any convenient manner to
the side of the casing in order to make the machine complete as a whole and self
contained.
In such cases when it is desired that the pump should not be attached to the
casing of the machine, it may be removed to any convenient distance from the
machine, but of course retaining the special arrangement at the bottom of
the extractor casing as a supply or reservoir tank.
In order that our invention may be properly understood and readily carried
into effect we have hereunto appended three sheets of drawings of which
Figure 1 is an elevation partly in section and
Figure 2 is a plan of the centrifugal machine.
Figure 3 shows the pump detached from the machine.
A is the casing of the machine, B the basket. The spindle C of the basket has
attached to it a ring D carrying a number of buckets E forming the turbine. The
turbine is driven by a force pump F attached to the framework as shown in
Figures 1 and 2 or detached as shown in Figure 3. The bottom of the casing of
the extractor is formed into a reservoir for supplying water to the force pump.
The water after being used for driving the turbine falls back into the reservoir.
The water is supplied to the pump from the reservoir by the pipe G and forced
along the pipe H to the nozzle I where it is discharged against the buckets E.
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 hydro-extractors the combination of a reservoir forined in the casing of the
machine with a force pump for driving a turbine attached to the spindle of the
revolving basket.
