Gentleman "IMPROVEMENTS IN OR CONNECTED WITH APPARATUS FOR PURIFYING
FOR OBTAINING MOTIVE POWER FROM WATER
WATER OR WITH APPARATUS
"
a communication to me from Eugèno Couillant a person resident at Paris in the
Republic of France
.
This Invention has for its object to provide an apparatus for pumping or raising
water for obtaining motivo power therefrom or for other purposes wherein a
compensation is obtained by which the water pumped or drawn in can be elevated
to any height without other effort than that which is employed to act upon the
actuating parts to elevate the water from the level of the supply up to a level but
a short distance above this as hereinafter explained.
The following is a description of an arrangement of apparatus according to this
Invention. Two cylinders are provided in each of which is arranged a piston
operated through connecting and piston rods by a beam or lever supported by and
turning upon a fixed fulcrum at about its centre. The piston of cach cylinder is
provided with a valve or valves opening upwards which are shut as the piston is
elevated in such a manner that the admitted water is confined in a receptacle above
the piston. The said receptacle of each of the cylinders is provided at top with a
valve opening upwards and is connected by a flexible pipe to a valve box provided
with valves also opening upwards and supported by the aforesaid beam or lever.
The said valve boxes are in each case joined by other flexible tubes to the pipes or
passages where the water is gathered in columns to be ultimately diverted for use
say to a hydraulic motor.
The action of the apparatus is as follows:-The beam or lever being oscillated
upon its fulcrum causes the pistons of the cylinders to be alternately raised and
lowered the one rising while the other is descending. The piston of the one
cylinder when raised has its valve or valves shut and the water opens the valve at

page_text: the top of the said receptacle above the piston and the water passes into the
flexible pipe above and ultimately the said valve shuts under the weight of the
water so introduced. Meantime the piston of the other cylinder descends and its
valve or valves open to let in the water to the receptacle above the said piston to
the level of the external supply and the said valve or valves then close at the same
time that the beam or lever is raised on this side to force the contents of the said
receptacle through the valve and into the flexible pipe above it is described with
regards to the cylinder on the opposite side. In repeating in this manner the
movement of the beam or lever the water is alternately raised into the pipes above;
the valves in the valve boxes opening to admit the said water the accumulated
contents of the one column of water acting on the beam or lever on one side and
counterbalancing the weight of the other column of water on the other side which
necessarily gives an alternate compensation of the two liquid columns so that
however bigh they may be there is no increased effort necessary in operating the
apparatus the water being raised. to any height without other effort than that which
is necessary to elevate the liquid from the level of the supply up to the level of the
operating beam or lever.
The number and arrangement of the pistons and cylinders may be varied as also
may the means employed for operating the pistons for example a handle or
equivalent device may be used instead of the beam provided that the counter-
balancing or compensating effect of the columns be utilized- as herein before
described.
