IMPROVE- MENTS IN OBTAINING MOTIVE POWER
Year: 1864

page_text: LETTERS PATENT to Abraham Hawkes, of 120, High Street, Charlton,
Dover, in the County of Kent, Baker, for the Invention of "IMPROVE-
MENTS IN OBTAINING MOTIVE POWER."
Sealed the 26th May 1865, and dated the 30th November 1864.
PROVISIONAL SPECIFICATION left by the said Abraham Hawkes at the
Office of the Commissioners of Patents, with his Petition, on the 30th
November 1864.
I, ABRAHAM HAWKES, of 120, High Street, Charlton, Dover, in the
County of Kent, Baker, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN OBTAINING MOTIVE POWER," to be as follows :—
This Invention relates to a peculiar arrangement and combination of
machinery or apparatus with a view to the obtainment of motive power, and
consists in the employment of an overshot water wheel, upon the axis of which
is fixed a large spur wheel which gears into a smaller spur wheel fast on a
second shaft. This shaft carries a large driving pulley, which by means of a
belt gives motion to the rigger of a centrifugal pump. The suction pipe of
this pump is turned upwards at the lower end, and is there provided with a
turbine wheel driven by the water which has already been used in working
the overshot wheel. This water after passing through the turbine wheel is
drawn up by the centrifugal pump and raised to a spout which directs it into
the buckets of the water wheel, the water in this arrangement being worked
over and over again without running to waste. The power to be obtained is
derived from the combined force or action of the water wheel and the turbine.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ABRAHAM
HAWKES, of 120, High Street, Charlton, Dover, in the County of Kent,
Baker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of November, in the year of our Lord
One thousand eight hundred and four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Abraham Hawkes, Her special license that I, the said Abraham
Hawkes, my executors, administrators, and assigns, or such others as I, the
said Abraham Hawkes, my executors, administrators, or assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVE-
MENTS IN OBTAINING MOTIVE POWER," upon the condition (amongst others)
that I, the said Abraham Hawkes, by an instrument in writing under my
hand and seal, 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 immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Abraham Hawkes, 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 follow-
ing statement, reference being had to the Sheet of Drawings hereunto annexed,
and to the letters and figures marked thereon; that is to say :-
My Invention relates to a peculiar arrangement and combination of
machinery or apparatus with a view to the obtainment of motive power, and
consists in the employment of an overshot water wheel, upon the axis of which
is fixed a large spur wheel which gears into a smaller spur wheel fast on a
second motion shaft. This shaft carries a large driving pulley, which by
means of a belt gives motion to the rigger of a centrifugal pump. The
suction pipe of this pump communicates at the lower end with the discharge
orifice of a turbine wheel driven by the water which has already been used in
working the overshot wheel. This water after passing through the turbine
wheel is drawn up by the centrifugal pump and raised to a spout which

page_text: directs it into the buckets of the water wheel. The power to be obtained is
derived from the combined force or action of the water wheel and the turbine.
The Drawing annexed represents a partial sectional elevation of my com-
bined machinery for obtaining motive power. A is the overshot water wheel,
and B a large spur wheel on the main shaft thereof gearing into a smaller
spur wheel C fast on the second motion shaft D. E is a large driving drum
or pulley also fast on the shaft D for the purpose of actuating by means of a
driving strap F a centrifugal pump or other suitable water elevator G. The
suction pipe H of the pump communicates at its lower extremity with the
upper and under discharge orifices of a turbine I, such orifices being covered
by the cases K, K, from which branch pipes L, L, lead and unite together in
the bend L' of the suction pipe. The discharge pipe M of the pump conveys
the water which has acted upon the turbine into a tank or spout N, whence
it again flows into the buckets of the overshot water wheel, and after leaving
the buckets passes by the pipe O to the turbine to be again elevated by the
pump. Power may be taken from the vertical shaft P of the turbine, or from
the main shaft Q of the water wheel, or from both combined, if preferred. In
starting the machinery it is of course necessary to have a sufficient reserve of
water ready elevated to enable the water wheel to commence its rotation, and
therefore it will be adviseable to have a tank in connection with the spout N,
into which tank the water should be elevated by the pump. If desired the
turbine may be dispensed with, using only the pump and water wheel.
Having now set forth the nature of my Invention of "Improvements in
Obtaining Motive Power," and explained the manner of carrying the same
into effect, I wish it to be understood that under the before in part recited
Letters Patent I claim, the obtainment of motive power substantially in the
manner and by the machinery herein-before described.
In witness whereof, I, the said Abraham Hawkes, have hereunto set
my hand and seal, the Twenty-fourth day of May, One thousand eight
hundred and sixty-five.
ABRAHAM HAWKES. (L.S.)
