GEORGES JUSTIN JOSEPH LEGRAND, 77, Clapham Road London S.W.
Engineer do hereby declare the nature of this invention to be as follows.:―
A principal or perpetual motor by means of a column of light liquid being held
up on one side of a tube by a heavy liquid keeping a level line at bottom of said
tube or recipient, the other side of the tube or recipient being empty or free of any
liquid whatsoever and an endless band or chain carrying cylinders or balls, hollow
or full, of any material, metal, or substance which revolve upon said chain and rest
upon pulleys one at top and one at bottom the pulleys revolving from their centers
upon ball bearings or other anti-friction rollers or bearings the cylinders or
balls, etc., etc., on the one side of the tube or recipient divided by a partition
ascending in the column of liquid and on the other side descending through the
tube or partition where there is no liquid until reaching the level column of heavy
liquid, mercury sulphuric acid or any other dense liquid through which they again
reascend, the balls, etc., in the heavy liquid being equal in number and having the
same strain upon them upon each side of the pulley or wheel upon and with which
they revolve, those balls in the column of water or very light liquid being the driving
force or power will continually ascend. Caps or valves are arranged in the
recipient to allow of liquid draining off or replenishing same.
A brake is used either by a heavy column of liquid pressing upon a piston in a
cylinder and a rod with a band attached applying brake upon the circumference of
one or more of the pulleys, or by a float hollow material being pressed upwards
tightening pulleys as said by the heavy liquid upon which it floats these brakes are
supplied with long levers to overcome their brake power and to allow of the motor
to revolve, any other brake may be used.
Gear wheels can be added to the pulleys for more speed and from them or the
pulleys or wheels to which they are connected as also the pulleys, the power is
given to any machinery outside.
The motor can be buried in the ground in a tank full of cool liquid or refrigerated
liquid or refrigerated air to keep liquids in recipient cool, or one side of recipient,
in which there is no light column of liquid can be liquid jacketted in a tank full of
cool liquid or refrigerated liquid or refrigerated air and the motor can work a small
refrigerating apparatus for the sake of keeping all liquids cool and air also in.
tanks or jackets. Pumps or other liquid raisers may be used to take out of the empty
column or division any liquid that may enter it on the motor revolving and to
repump same into the column into which liquid is kept forming the ascending column
or the liquid may be allowed to run to waste from the one column and a small
supply of liquid to refill the column into which water is to be.
The endless band with floats may be caused to go through a series of empty and
full columns of liquid all supplied with pulleys or wheels, and taps or pumping
devices, etc., or several of these motors may be placed side by side or in any
fashion and geared together or not, so as to work conjointly or alone.
Wiping rollers may be used for the purpose of wiping off the liquid from the.
chains or endless bands and from the rollers or balls, etc., as they ascend from out.
of the full column or columns of liquid to descend free of all liquid into the empty
column or columns forming the tubes or partitions.
The tubes or recipients or tanks with divisions dipping into heavy liquid at
bottom of same or with pipes dipping into heavier liquid at bottom of same may
be made of any material, metal, or substance and in any shape or form, as also

page_text: may be the tanks or reservoirs made in the ground and into which above described
motors are preferably placed for convenience.
A governor, to regulate the speed of the machine can be arranged by the
governors forcing down into the liquid a hollow float which can be regulated for
length and will partly or wholly apply the brakes on the motor.
Reversing gear can be applied to the motor by throwing on extra toothed
wheel into gear as the motor itself. cannot be reversed..
If oil be used in one column as the lighter liquid, then the motor. is self-lubri-
cated, if water or other liquid be' used 'then oiling boxes for the moving parts
are provided for.

An Improved Motor.
I, GEORGES. JUSTIN JOSEPH LEGRAND, formerly, of 77 Clapham Road, in the
County, of Surrey, but now of 11 Loraine Place, Holloway Road; in the County
of Middlesex,. Merchant,, do. hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly, described and ascer-
tained. in and by, the following, statement :-
My invention relates to an improved motor which is operated by the-weight and
floating power of a number of light balls or cylinders which engage with wheels or
levers working in water or other liquids heavier than the balls or cylinders.
To clearly explain my invention I show in the accompanying diagram. one form
of my improved motor for the purpose of illustration..
This consists of: a.tanka in which works. a large wheel. (or levers) b, the tank.
being filled with water upito a certain level as shown. In this tank is contained a
second tank c which may hold mercury or a suitable fluid heavier than the water in
tánk:a: In tank:a: works: a second, wheel (or levers) d. Both wheels band d have
a number of curved arms or floats upon them, each arm or float. representing a
lever the number of which in the wheel. b are greatly in excess of those in. the
wheel'd the diameter of which latter is also less than that of the wheel.b. The
shaft of the wheel d is geared to the shaft of the wheel b or as shown is. connected.
to it by means of aistrap or chainte passing around pulleys fg. The shaft of the
wheelid is also connected to a spindle, by gearing or by a strap or chain i. The
shaft carries a number of arms; which work in a tube or chamber k. such tube.or.
chamber being: closed against. the entrance of water. thereto.. Both ends of this.
tube are open; the upper being above the level of the water in the tank a while the
lower dips into the tank c the outlet being arranged close to the periphery of the
wheeled on the extremity of the levers corresponding thereto..
Attas suitable point in the tube k is arranged an overflow, tube, which. will.
discharge into a tank or to waste..
The tank a is also supplied, with water from a suitable pipe, to, maintain: the
proper level therein, such: supply being controlled by a ball, floats or other
automatic device:
In the tank: a above the water level are also situated wiping, rollers.m.
The curved arms or floats on the wheels b and dare preferably open or forked.
so as to offer less resistance to their passage through the water and in the case; of
the wheel dito allow them to pass through a forked plate n placed at: an angle as.
shown in the tankicrsuch, plate serving to remove from the floats or curved arms of.
the wheel d the balls or cylinders to which are hollow or of wood, or some, light
materialicapable of floating in both of the liquids in the tanks a.and.c.
The operation is as followe
As the balls or oylinders o fall down.the.tube, or chamber. k, which, is otherwise
empty, their weight will partly cause the armsj to revolve but the latter will also

page_text: be revolved by the strap or chain i as will be hereafter explained, the effect being
that the balls beneath the arms j are forced down the tube, through the mercury
or other heavy liquid in the lower part thereof until they issue through the lower
end of the tube the mouth of which may be arranged to direct the balls into the
floats or curved arms of the wheel d. As these balls rise through the heavy
liquid they will turn the wheel d and with it the pulley g, strap or chain i, shaft h,
and arm j, until they are removed from the floats by the plate n when they will
float to the surface of the liquid and be directed by the curved mouth of the
tank c into the curved arms or floats of the wheel b, or in place of this arrange-
ment they may be directed into the floats by means of a rotating arm or arms
operated in any suitable way. As the balls collect in the floats of this wheel b
their buoyancy will cause the wheel to be rotated which will rotate the pulley f
and strap or chain e the latter having been previously started by the rotation of
the wheel d.
The balls as they rise with the wheel b will be delivered between the loosely
running rollers which will wipe the superfluous moisture therefrom and will
be again delivered down the tube k where their weight will be utilized as before
described.
The overflow pipe 1 is for the purpose of removing any water which may collect
in the tube k from the balls o.
The
power produced is preferably taken from the shaft of the wheel b upon
which if required some suitable brake device may be placed while for the purpose
of reversing the motor a gear wheel may be provided which will be thrown into
gear when required.
It should be understood that the particular motor referred to is only shown to
illustrate how my invention may be carried into effect as there are other ways of
utilizing the weight and buoyancy of the balls cylinders or the like and the inter-
geared wheels or levers in some of which arrangements the mercury or heavy
liquid may be dispensed with, such as where the tube is arranged to deliver the
balls below the surface of the water to two wheels arranged side by side or geared
together means being provided for delivering a greater number of balls to one
wheel than the other and means for collecting the balls from either wheels and
delivering them back to the tube.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. A motor consisting of a receptacle containing a liquid or liquids, intergeared
wheels or levers, and balls, cylinders or the like, the weight and buoyancy of which
is utilized to operate the wheels or levers substantially as described.
2. The improved motor substantially as described and illustrated.
