I, AUGUSTE LACOMME, 2, Carlisle Street, Soho Sq", do hereby declare the
nature of the said Invention for "AN APPARATUS, THE PNEUMATO-LIQUID MOVER,
APPLICABLE TO ALL BRANCHES OF INDUSTRY WHICH REQUIRE A FIRST PRIKE POWER,"
to be as follows:-
Its principles has the physical law that a body plunged in liquid loses of its
weight the volume of the displaced liquid, that is to say, by inverted reason,
any object lighter than a liquid must reascend to the surface a weight equi-
valent to the specific heaveness of this liquid, by reason of the lightiness of the
volume of the object. This apparatus is composed as follows:-
No. 1. A reservoir filled with any liquid whatever.
2. A prismatic axis; the number of sides is more or less large according to
the power that one wishes to give to the apparatus, that is to say, it may be
hexagonal, octangular, decagon, etc.
3. A pivot at each extremity of the axis, which rest on cousinets or vises of
pression is supported on each side of the reservoir.
4. A hole on every longitudinal surface of this prismatic axis comes to the
opposed parallel surface (none of these holes meets in the same direction).
5. A lever mor or less long, according to the power that one wishes to give,
goes through each of the holes practiced on the longitudinal surface of the
axis; this lever slides easily from one extremity to the other.

page_text: 6. A hollow recipient in the shape of a balloon, closed hermeticaly, filled
either with air or gas, is at each extremity of this lever.
7. A toothed wheel (No. 1) is fixed at an extremity of the prismatic axis ;
this wheel works into another wheel, No. 2, with the assistance of several
pinions.
8. Another wheel, No. 2, working with the wheel No. 1, causes the crank
No. 9 to move.
9. A crank moves by the wheel No. 2; it communicates to a piston, which,
by the rotation given to it by the wheel No. 2, sends from top to bottom the
lever which present itself to the perpendicular line.
This apparatus has for object to obtain a first prime power without having
recourse to any other thing than liquid and gas. It works in this manner::-
The prismatic axis No. 2 run through by levers No. 5, which have each at
their extremity an empty recipient, hermeticaly closed, No. 6; for instance,
the apparatus is three feet hight; the octangular axis is fixed in the middle;
the levers have a foot and a half, comprising the recipient. As these lovers
are constantely repulsed towards the axis by the driving piston, whenever they
come to the perpendicular they describe a curve of three feet in diameter, and
this work is always a first prime mover as far as the perpendicular, the acting
levers try to reascent. This is the effect of it.:-
.It is easely to understand that the ascendent impelling force is powerful and
the resistance small.
When the motion is one given it becomes constant, as it obtains the con-
tinued rotation; the lever which is on the perpendicular must be send to tho
inferior part of the apparatus. This object is attained by the means of a piston
crank or a wheel; the piston strikes invariably on the recipient when it comes
on the perpendicular by the rotation of the axis, it drives down the recipient,.
sends it back near the axis, and consequentely the lever is precipitated in all its
lenth to the botton of the reservoir, where it assumes again the ascendant force.
and comes again to the perpendicular, to be again driven down, etc., &.
