page_text: LETTERS PATENT to Thomas Woodward, of Ledbury, in the County of
Hereford, for the Invention of "IMPROVEMENTS IN MACHINERY OR APPA-
RATUS FOR RAISING OR ELEVATING SEWAGE WATER AND OTHER LIQUID
MATTERS, ALSO APPLICABLE AS A MEANS OF AFFORDING MOTIVE POWER FROM
WATER.'
Sealed the 12th April 1867, and dated the 16th October 1866.
PROVISIONAL SPECIFICATION left by the said Thomas Woodward at
the Office of the Commissioners of Patents, with his Petition, on the
16th October 1866.
I, THOMAS WOODWARD, of Ledbury, in the County of Hereford, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY OB
APPARATUS FOR RAISING OR ELEVATING SEWAGE WATER AND OTHER LIQUID
MATTERS, ALSO APPLICABLE AS A MEANS OF AFFORDING MOTIVE POWER FROM
WATER," to be as follows:-
This Invention relates to certain improvements in the construction and
arrangement of machinery or apparatus for the purpose of raising or elevating
sewage matters, water, and other liquids, in order that they may be discharged
by pipes or drain tubes to any desired place, the apparatus being also appli-
cable as a means of affording motive power from water by elevating water to

page_text: a considerable altitude, and thus affording power by its consequent pressure
and fall either for a water wheel or hydraulic press, or other appliance.
I propose to construct a reservoir at the side of a river embankment, tidal
harbour, or other situation exposed to the influence of the tides, into which
reservoir or receptacle the sewage matter or water to be raised is collected
and stored. I place in the reservoir a double or reverse pair of Archimedean
screw tubes set on an oblique shaft supported in a bearing at the bottom of
the reservoir, and in another fixed in the wall or brick work of the embankment
or masonry. Near the reservoir I place a barge, caissoon, or other body having
considerable power of flotation or buoyancy, and yet of a considerable weight;
this may be placed in an archway or recess, and should be secured by mooring
chains or otherwise. In the centre it supports a vertical shaft or toothed rod
which gears with a pinion set on a shaft containing a large toothed wheel
which in turn gears with a second pinion, and so on, after the manner of
multiplying gear, until the last toothed wheel of the series comes into
with
gear
a pinion on the shaft of the oblique Archimedean screw tube shaft, whereby
it. will follow that the rise and fall of the tidal water will cause the barge or
caissoon to rise and fall carrying with it the vertical toothed rod, and turning
the wheels and screw so as to raise the contents of the reservoir. The descent
of the tide lowers the barge or caissoon, which being of sufficient weight
exercises a gravitating power and reverses the action of the multiplying
gearing, causing the other screw tube to come into play, and continuing the
elevation of the sewage or water.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Woodward in the Great Seal Patent Office on the
16th April 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
WOODWARD, of Ledbury, in the County of Hereford, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of October, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Woodward, Her special licence that I, the said Thomas
Woodward, my executors, administrators, and assigns, or such others as I, the
said Thomas Woodward, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times

page_text: 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 Isle of Man, an Invention for "IM-
PROVEMENTS. IN MACHINERY OR APPARATUS FOR RAISING OR ELEVATING SEWAGE
WATER AND OTHER LIQUID MATTERS, ALSO APPLICABLE AS A MEANS OF AFFORDING
MOTIVE POWER FROM. WATER," upon the condition (amongst others) that I,
the said Thomas, Woodward, my executors or administrators, by an instru-
ment 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 months next and imme.
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Thomas Woodward, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement.
This Invention relates to certain improvements in the construction and
arrangement of machinery or apparatus for the purpose of raising or elevating
sewage.matters, water, and other liquids, in order that they may be discharged
by pipes or drain tubes to any desired place; the apparatus being also appli-
cable as a means of affording motive power from water by elevating water to
a considerable altitude, and thus affording power by its consequent pressure
and fall either for a water wheel, or hydraulic press, or other appliance.
I propose to construct a reservoir at the side of a river embankment, tidal
harbour, or other situation exposed to the influence of the tides, into which
reservoir or receptacle the sewage matter or water to be raised is collected
and stored. I place in the reservoir a double or reverse pair of Archimedean
screw tubes set on an oblique shaft supported in a bearing at the bottom of
the reservoir, and in another fixed in the wall or brickwork of the embank-
ment or masonry. Near the reservoir I place a barge, caissoon, or other
body having considerable power of flotation or buoyancy, and yet of a con-
siderable weight; this may be placed in an archway or recess, and should be
secured by mooring chains or otherwise. In the centre it supports a vertical
shaft or toothed rod which gears with a pinion set on a shaft containing a large
toothed wheel which in turn gears. with a second pinion, and so on, after the
manner of multiplying gear, until the last toothed wheel of the series comes
into gear
of the oblique Archimedean screw tube
shaft, whereby it will follow that
with a pinion on the shise and fall of the tidal water will cause
الامت
the barge or caissoon to rise and fall carrying with it the vertical toothed rod,

page_text: and turning the wheels and screw so as to raise the contents of the reservoir.
The descent of the tide lowers the barge or caissoon, which being of sufficient
weight exercises a gravitating power and reverses the action of the multiplying
gearing, causing the other screw tube to come into play, and continuing the
elevation of the sewage or water.
In order that my said Invention may be completely understood, I annex the
accompanying Drawing, which represents a side elevation (partly in section)
of a portion of the apparatus sufficient as an example of a more extended
arrangement.
a, a, is a section of the reservoir, and 6 the oblique shaft surrounded by the
Archimedean screw tube c, having an inlet at d and an outlet at the upper
extremity e; the shaft is set in bearings at f, f, and is worked by the spur
wheel g. The tube by its revolution takes up the sewage matter or water
from the reservoir and elevates it to the upper outlet, where it is discharged as
required into any conduit or other receptacle. h is a barge, vessel, caissoon,
or buoyant apparatus filled with air, in which the vertical toothed rack i is
set; the rack traverses bearings in the horizontal beam k, and gears with the
pinion set on the cogged wheel 4, which works the pinion m set on the
second toothed wheel m³, the latter wheel operating the spur wheel
9, whereby
multiplying speed is effected. The caissoon or buoyant vessel rises and falls
with the tide, as before described, and therefore by placing a reverse Archi-
medean tube around the oblique shaft the sewage or water may be raised
equally by the rise and fall of the tide.
The multiplying gearing may be increased if required by a repetition or con-
tinuation of pinions and toothed wheels, but much will depend on the work to
be done. The machinery may be increased by forming pinions on each side
of the cogs, and applying a duplicate set of cogs and pinions working side by
side so as to operate another elevating tube and oblique shaft on the opposite
side; so also by applying a toothed wheel to the upper part of the oblique
shaft, a second shaft and tube placed parallel with the one described, and turned
by toothed gearing, may assist in elevating the sewage matter or water from
the reservoir,
Having now described the nature of my said Invention, and the manner in
which the same is to be performed, I would remark that I do not limit
myself to the precise details and configuration of parts I have described and
shewn, as the same may be varied or modified without departing from the
principles of my Invention; but what I claim are the general arrangement
and combination of parts forming the improvements in machinery or appa-
ratus for raising or elevating "sewage water and other liquid matters; also

page_text: applicable as a means of affording motive-power from water, substantially as
herein specified.
In witness whereof, I, the said Thomas Woodward, have hereunto set my
hand and seal, this Thirteenth day of April, in the year of our Lord
One thousand eight hundred and sixty-seven.
