MENTS IN OBTAINING MOTIVE POWER, AND IN MACHINERY OR
THEREFOR"
" IMPROVE-
APPARATUS
This Invention relates to the construction of a motive power engine in which the
power is produced from a liquid, which falling into vessels and pipes suitably
arranged produces a reaction, so much exceeding the action as to be sufficient to
produce a certain amount of power over that which is required to again raise the
liquid to overcome friction, and the resistance of the air.
In carrying out the Invention I provide a suitably shaped vessel, into which
opens one end of a pipe having three elbows, and is provided with small capillary
holes for allowing communication between the annular space in turning, and the
atmosphere. The said tube discharges the liquid vertically into a cylindrical vessel
firmly fixed to the engine, and is formed with an annular space, around which
turns a ring forming part of the elbowed pipe and the first described vessel, which
can thus turn around the axis of the cylindrically shaped vessel, which latter is
concentrically fixed to a larger cylindrical vessel, into which the liquid from the
former falls for the purpose of better regulating the motion, the water being raised
by a pump, the suction tube of which opens into the outer cylindrical vessel.
The first described vessel being filled with liquid is acted on by the pressure of
the piston of the safety valve. The side opposite to the orifice, and that of the
discharge, being sufficiently distant from the end of the bent pipe a hydrostatic
pressure or reaction will be produced in the vessel.
In the elbowed tube a portion only of the horizontal pressure is destroyed, that
which remains is small in proportion to the said hydrostatic pressure.
For regulating the action I employ a cock actuated by a conical pendulum
governor, set in motion by a vertical shaft driven by bevel gearing on the axles of
the wheels of the engine, the wheels being fixed on their axles. The driving shaft
of the engine may work a suction pump for raising the liquid. The work will
depend on the speed of the engine or locomotive, but this defect may be remedied
by employing the apparatus hereinafter described. This apparatus is constructed
on the same principle as that hereinbefore described, and consists of a vessel having
two vertical sides, a top and bottom, a vertical cylindrical side, and a side which

page_text: should have the form of a paraboloid. A part of this side is formed by a cylinder
having a piston driven by an excentric, for the purpose of always keeping the
vessel full of water, thereby reducing to a minimum the movement of a cylinder in
communication with the vessel. One of the vertical sides has a number of openings,
from which pass tubes for carrying the liquid into a second vessel. The liquid
subjected to the load resulting from the centrifugal force runs from the first named
vessel into the second vessel through the said pipes.
To keep the reservoir full of liquid I employ a cylinder having a piston, which
rises and falls similarly to the pump hereinafter described. This suction and force
pump is fixed to the cover of the cylinder, and the two vessels and the pump body
are fixed by bars to a plate, which can revolve on a vertical axis formed in this case
by the vertical portion of the suction pipe which carries an excentric, which gives
motion to the pump rods. A conical pendulum governor regulates the motion. On
the hereinbefore described turning plate is placed a centrifugal pump, the axis of
which is vertical, and the suction pipes of which commencing from the cylindrical
vessel of the motive engine passes into the interior of the fixed shaft forming the
excentric, and opens into the pump. The delivery pipe passes from the pump to
the safety valve, and opens into the first described vessel of the motive engine.
This pipe is in two parts, one fixed to the fixed part of the pump, and the other
fixed to one end of the vessel, so as to turn with it. Suitable valves are provided
where required.
