July 1865. A communication from abroad by Jean Louis Celestin

I, WILLIAM EDWARD GEDGE, of the Firm of John Gedge and Son, of
No. 11, Wellington Street, Strand, in the County of Middlesex, Patent
Agent, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE MEANS OF AND APPARATUS FOR RAISING WATER FOR AGRICULTURAL AND
OTHER USEFUL AND ORNAMENTAL PURPOSES,") a communication from abroad by
Jean Louis Celestin Achard, of No. 15, Passage des Petites Ecuries, Paris,
France,) to be as follows:-
The utility of this improved mill consists in raising water to heights more
or less elevated, according to requirement, afterwards using it by causing it to
fall on to a hydraulic wheel, which will drive agricultural machines and for
various agricultural purposes, washing troughs, for example, also in case of
fire, and for ornamental purposes in using it for fountains and pieces of
ornamental water.
Firstly, the method of using the fall of water on a hydraulic wheel is by
means of an endless jointed chain carrying buckets which passes over a
wooden roller receiving a rotary motion from a windmill; this chain is
therefore gifted with a rectilineal ascending and descending movement, the
buckets plunging into the well and rising again full of water, which they pour
into an upper basin, at the lower part of which is an orifice, by which the

page_text: water is to flow on to the bydraulic wheel; this orifice is furnished with a
sump regulating the outflow, so that the same water level is always maintained
in the basin. With a mill having 8 sweeps of, say, 39 feet long, by about
8 feet broad, a product of rather more than 13 gallons a second or 792 gallons
per minute may be raised to a height of about 91 feet above the water level
in the well, and an effectivo 9-horse power be obtained from the hydraulic
wheel. Wooden washers, fixed to the chain, and moving in hollow tubes, may
be substituted for the buckets.
Secondly, the arrangement for simply raising water for agricultural and
ornamental purposes is composed of two hollow tubes, one of which descends
to the water level, and an enless chain, to which are fixed wooden washers of
a diameter equal to the inner diameter of the tubes; this chain passes. like
that of the preceding arrangement, over a roller, to which a rotary movement
is given by a windmill. Thus the chain has a continuous rectilineal ascending
and descending movement. The washers fixed to this chain draw the well
water with them into the tube, pouring it out at its upper orifice. A cylinder
surrounds the two tubes, and the water issuing from one of them fills the
cylinder until having attained a sufficient beight it is allowed to run off at the
lower part of the second tube, provided with a cock for this purpose. The
samo water level is thus always preserved in the cylinder. The quantity of
water raised per minute will vary with the size of the windmill and the height
to which it is to be elevated.
