Year: 1872

page_text: LETTERS PATENT to George Rydill, of Grove House, Dewsbury, in the
County of York, for the Invention of "IMPROVEMENTS IN HYDRO-
EXTRACTORS OR CENTRIFUGAL MACHINES FOR OBTAINING AND APPLYING MOTIVE
POWER FOR THE PURPOSE OF DRAINING AND DRYING ANIMAL AND VEGETABLE
SUBSTANCES, EARTHS, AND COMPOSITIONS.”
"
Sealed the 7th March 1873, and dated the 1st October 1872.
PROVISIONAL SPECIFICATION left by the said George Rydill at the
Office of the Commissioners of Patents, with bis Petition, on the
1st October 1872.
I, GEORGE RYDILL, of Grove House, Dewsbury, in the County of
York, do hereby declare the nature of the said Invention for “IM-
PROVEMENTS IN HYDRO-EXTRACTORS OR CENTRIFUGAL MACHINES FOR OBTAINING AND
APPLYING MOTIVE POWER FOR THE PURPOSE OF DRAINING AND DRYING ANIMAL AND
VEGETABLE SUBSTANCES, EARTHS, AND COMPOSITIONS," to be as follows :—
This my improved Invention has the advantage over hydro-extractors
or centrifugal machines now in use of more effectually working the

page_text: same, and enabling them to be worked to advantage in the cottage for
the removal of liquid moisture from clothes, as well as liquid moisture
from piece goods, animal and vegetable substances, earths, and com-
positions in factories and other works, avoiding the necessity of using a
steam cylinder engine, friction and cog wheel gear, shaft, or strap, which 5
are usually fixed and worked over the top or underneath hydro-extractors
or centrifugal machines.
My improvements consist in forming what I term a double bottom to
hydro-extractors or centrifugal machines, and having a shaft or spindle
standing in a vertical position, which supports and carries what is called 1
a drum, cage, or basket, which is firmly secured with key and bolts to
the shaft or spindle working in the centre of the hydro-extractor or
centrifugal machine; this shaft or spindle is carried through an opening
left in the centre of the first or inner bottom of the hydro-extractor or
centrifugal machine, which opening is made up by a moveable plate or 1
plates, carrying a stuffing box, and the shaft or spindle rests on a foot
step fixed in the centre of the second or outer bottom casing of the
hydro-extractor or centrifugal machine. On to this shaft or spindle I
fix a wheel of any required diameter, which might be termed a turbine
wheel, forming sunken buckets in its centre, with small veins or side
buckets forming recesses on each side of the sunken buckets, or the
sides may be smooth. This wheel is turned up true on the face and
sides, and is made to fit and work true in a confined space formed
betwixt the inner and outer double bottom of the bydro-extractor or
centrifugal machine, which I make in one or more parts; a projection or
division of metal is made to fit the turbine wheel so as to form a division
betwixt the inlet and outlet of the propelling power, answering as a but-
ment for the propelling power of steam, compressed air, or water from
hydraulic mains, which is the most suitable power for propelling hydro-
extractors or centrifugal machines in dwellings.
When steam is the power employed it is conveyed direct from a high-
pressure steam boiler, and the supply of steam is regulated by a valve as
it passes along the pipes leading to the turbine wheel, which strikes the
buckets or veined wheel on one side of the division or butment, giving
out its propelling power upon the wheel, and the escape or outlet is
made on the other side of the division or butment; or the escape or

page_text: opening I make at any part of the circumference of the turbine wheel,
and the escape steam is conducted through a coiled pipe into a room for
heating air, or I condense the steam with cold water for washing
purposes. The steam, compressed air, or water from hydraulic mains,
striking one side of the turbine wheel on one side of the division or
butment speedily gets the turbine wheel, shaft, or spindle, drum, cage,
or basket containing the material to be freed from liquid moisture on
to a high rate of speed, which caused the material to throw off its liquid
moisture against the sides of the hydro-extractor casing, which is carried
through an opening in the side of the hydro-extractor or centrifugal
machine, and when the speed or centrifugal force which the drum, cage,
or basket has attained requires to be stopped for emptying or refilling, I.
open a valve in connection with the turbine wheel, and allow high-
pressure steam, compressed air, or water from hydraulic mains to strike
the wheel on the opposite side to the propelling one, which answers the
purpose of stopping or braking the turbine wheel by striking the
buckets or veins in an opposite direction.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Rydill in the Great Seal Patent Office on
the 1st April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
RYDILL, of Grove House, Dewsbury, in the County of York, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of October, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said George Rydill, Her special licence that I,
the said George Rydill, my executors, administrators, and assigns, or such
others as I, the said George Rydill, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands, and

page_text: Isle of Man, an Invention for "IMPROVEMENTS IN HYDRO-EXTRACTORS OR
CENTRIFUGAL MACHINES FOR OBTAINING AND APPLYING MOTIVE POWER FOR THE
PURPOSE OF DRAINING AND DRYING ANIMAL AND VEGETABLE SUBSTANCES, EARTHS,
AND COMPOSITIONS," upon the condition (amongst others) that I, the said
George Rydill, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar montlis
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Rydill, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement :—
This my improved Invention has the advantage over hydro-extractors:
or centrifugal machines now in use, of more effectually working the
same and enabling them to be worked to advantage in the cottage for
the removal of liquid moisture from clothes, as well as liquid moisture
from piece goods, animal and vegetable substances, earths, and com-
positions in factories and other works, avoiding the necessity of using a 1
steam cylinder engine, friction and cog wheel gear, shaft, or strap, which
are usually fixed and worked over the top or underneath hydro-extractors
or centrifugal machines.
My improvements consist in forming what I term a double bottom to
hydro-extractors or centrifugal machines, and having a shaft or spindle
standing in a vertical position, which supports and carries what is called
a drum, cage, or basket, which is firmly secured with key and bolts to
the shaft or spindle working in the centre of the hydro-extractor or
centrifugal machine; this shaft or spindle is carried through an opening
left in the centre of the first or inner bottom of the hydro-extractor or ;
centrifugal machine, which opening is made up by a moveable plate or
plates carrying a stuffing box, and the shaft or spindle rests on a foot
step fixed on the centre of the second or outer bottom casing of the
hydro-extractor or centrifugal machine. On to this shaft or spindle I
fix a wheel of any required diameter which might be termed a turbine
wheel forming sunken buckets in its centre, with small veins or side

page_text: buckets forming recesses on each side of the sunken buckets, or the
sides may be smooth. This wheel is turned up true on the face and
sides, and is made to fit and work true in a confined space formed
betwixt the inner and outer double bottom of the hydro-extractor or
centrifugal machine, which I make in one or more parts; a projection or
division of metal is made to fit the turbine wheel so as to form a division
betwixt the inlet and outlet of the propelling power; answering as a but-
ment for the propelling power of steam, compressed air, or water from
hydraulic mains, which is the most suitable power for propelling hydro-
extractors or centrifugal machines in dwellings.
When steam is the power employed it is conveyed direct from a high-
pressure steam boiler, and the supply of steam is regulated by a valve
as it passes along the pipes leading to the turbine wheel which strikes
the buckets or veined wheel on one side of the division or butment,
giving out its propelling power upon the wheel, and the escape or outlet
is made on the other side of the division or butment in the escape or
opening I make at any part of the circumference of the turbine wheel,
and the escape steam is conducted through a coiled pipe into a room for
heating air; or I condense the steam with cold water for washing
purposes. The steam compressed air or water from hydraulic mains
striking one side of the turbine wheel on one side of the division or
butment speedily gets the turbine wheel, shaft or spindle, drum, cage,
or basket containing the material to be freed from liquid moisture on to
a high rate of speed which caused the material to throw of its liquid
moisture against the sides of the bydro-extractor casing which is carried
through an opening in the side of the hydro-extractor or centrifugal
machine, and when the speed or centrifugal force which the drum, cage,
or basket has attained requires to be stopped for emptying or refilling I
open a valve in connection with the turbine wheel and allow high-
pressure steam, compressed air or water from hydraulic mains to strike
the wheel on the opposite side to the propelling one, which answers the
purpose of stopping or braking the turbine wheel by striking the buckets
or veins in an opposite direction.

page_text: outer casing marked A, A, represents the outer casing; B, B, the drum,
cage, or basket which is attached and supported by the spindle or
upright shaft C. This spindle or shaft C passes down centrally through
an enlarged opening D, and terminates at a centre point E, which
spindle or shaft rests and revolves on a steel footstep or cup-shaped
block F; a wheel with suitable sunken buckets marked G is firmly
secured to the spindle or shaft C. The wheel with sunken buckets or
turbine marked G works within a cylinder with just as much clearance
room as is necessary for it to revolve freely without contact with the
sides of the cylinder. The steam, water, or compressed air working the 1
hydro-extractor or centrifugal machine is conducted to the wheel with
sunken buckets or turbine marked G through the pipe H. The tap or
valve in this pipe is made so that it will turn to allow the steam, water,
or air to act upon the veins or sunken buckets in order to put the drum,
cage, or basket into rapid centrifugal motion, or to turn so that the 1
pressure of steam, water, or air may serve to brake or stop the drum,
cage, or basket. I is the exhaust pipe for the steam, water, or air
after it has expended its force upon the driving or stopping side of the
wheel.
Figure 2 is a sectional plan of the hydro-extractor or centrifugal a
machine; A, A, represents the outer casing; C, the spindle or shaft;
G, the wheel with sunken buckets or turbine; ■, the inlet pipe; I, the
exhaust; J, J, J, J, the holes in the bed plate for bolting down the
hydro-extractor or centrifugal machine pipe marked; K is the inlet pipe
for high-pressure steam, water, or air for driving the drum, cage, or 2
basket, and the branch pipe L, the stopping or braking side.
The wheel with sunken brackets or. turbine in Figure 1 and 2 is given
to show how the steam, water, or compressed air may be applied for
working hydro-extractors or centrifugal machines among other descrip-
tions of turbine or other wheels I might have placed upon Drawings
with this Specification, but what I claim as my Invention is, to propel
hydro-extractors or centrifugal machines by the direct action of steam,
water, or compressed air acting upon a wheel attached to the spindle
or shaft carrying a drum, cage, or basket of a bydro-extractor or
centrifugal machine with veins, sunken buckets, turbine, or any other
form, the direct action of high-pressure steam, water, or air to work

page_text: hydro-extractors or centrifugal machines being the object of this my
patented Invention.
In witness whereof, I, the said George Rydill have hereunto set my
hand and seal, this Thirty-first day of March, in the year of our
Lord One thousand eight hundred and seventy-three.
