I, VICTOR COINE, of 37, Boulevard Bonne Nouvelle, Paris, in the
Empire of France, Engineer, do hereby declare the nature of the said
Invention for "A VERTICAL AERO-HYDRAULIC ENGINE WITH A DOUBLE ACTION,"
to be as follows:-
This machine is based upon the following well-known principles :--
1°. The difference in density between air and water.
2°. The elasticity and compressibility of air.
3°. The weight of liquids and the mobility and adhesion of their
molecules.
Its object is to replace the wheels turned by hand in workshops to
transmit motion to various small machines; it gives greater power than

page_text: those wheels with less fatigue to the workman; it may also serve as a
motive power for agricultural machines (which in many country places
cannot be used for want of power), as well as in the many small
manufactures of large towns.
Description of the Apparatus.-The apparatus is composed of two
circular basins united at the base and by an iron tie piecc. These basins
are open at the upper part in the shape of a truncated cone, and to these
cones are fitted two cylinders (one to each basin). Within each basin is
a hollow cylinder in which is placed a pipe of square section having at
each of its ends vessels made of vulcanized cloth and of a parallelopipedon
form. Two of the cloth vessels are fixed at the lower part outside the
apparatus, and to these are attached the connecting rods intended to
turn the double cranked driving shaft. In the middle of the pipes with
square section is a slide bar leaving the orifice free in the second basin
while closed in the first. This is effected by means of a horizontal
shifting movement given to a triangle provided with a handle to which
the cylinder rods are attached. In each of the cylinders outside the
basins is a piston furnished with a plate for closing the opening from
the basins to the outer cylinders; it is set on a jointed rod and put in
connection with the transmission shaft by means of an eccentric.
Working of the Apparatus.-To set the apparatus at work it is only
requisite to distend the two inverse vulcanized cloth vessels, and then to
produce the cylinder opening and closing movement by pulling the
handle in one direction and pushing it back in the contrary one in order
to set the driving shaft at work. To secure a working under constant
pressure the first basin has been filled with water, so that one of the
two vulcanized cloth vessels being distended and ready to collapse, the
piston of the outer cylinder being at the bottom of its stroke, the level
of the water is that of the basins; and when the pressure of the water
comes on the second vessel, the volume of the truncated cone being the
same as that of this vessel, then one of the pistons begins to rise under
power exerted at its base by the pressure of the water, the level of
which lowers in the basin until it is the same as in the cylinder. One
of the pistons is then at the top of its stroke, and the surface of the
water does not in any way hinder the distension of the vulcanized cloth
vessel. In the second basin the action is reversed; one of the vessels
being again distended an eccentric causes the piston to descend and to
the

page_text: force the water to its first level. There is consequently an alternate
motion between the two basins, and if the journey of the vulcanized
cloth vessels is the same as that of the elbows or cranks of the driving
shaft this latter will in this situation have made half a turn.
