hereby declare the nature of this invention to be as follows:-
It is known that every pressure exerted upon a gas or a liquid is imparted with a
proportional power to the surface to which it is transmitted; it is upon this law which
proceeds from Pascal's principle and upon the laws relating to the fall of bodies that
my new motor is based.
The principle upon which my motor is constructed is as follows :-
A piston in rising draws air into its barrel or cylinder through a valve at the
bottom of the said cylinder; the cylinder is also in communication by a pipe at its
lower part with an expanding and collapsing vessel or bag mounted upon a seat which
is formed with an opening in the centre corresponding with that of the pipe and of
the bag. Upon the bag is placed a table or platform of wood or metal for the
reception of weights. The apparatus being thus arranged if the piston be allowed to
fall freely, the pressure exerted by its own weight will force out the air from the
cylinder or barrel into the bag and will expand or distend this latter, thereby raising
the platform with a power which will be multiplied in proportion to the relation of the
surfaces of the section of the piston and of the bags; and this power will be increased
by the fall of the piston. (Law of the fall of heavy bodies.)
My motor is double acting being composed of 2 apparatus operating as above
described and coupled together so that the pistons and bags work alternately. On a
frame or platform which supports the whole of the apparatus are mounted two
cylinders or pump barrels. These cylinders should be bored and polished for their
whole length in order to avoid friction and escape of air. A suction valve is
fitted in a special chamber at the bottom of each cylinder so that the valves as
well as the bottom of the cylinders can be examined and cleaned without interfering
with the pistons. The pistons are of iron or steel, turned and polished with care;
they may be made hollow and filled with lead in order to increase their weight.

are covered with leather so as to soften the blow of the teeth of cams which raise

page_text: the pistons. Pipes of metal, leather or india rubber or other impermeable material,
put the lower parts of the cylinders in communication with the respective motor
bags and there are cocks for opening or more or less shutting off this
communication.
Pointers or indicators on the keys of the cocks and moving over an arc of a
graduated circle allow of the speed of the motor being regulated to a nicety.
There are cocks for the escape or in case of need, for the taking in, of air, and these
cocks may be fitted with whistles. The bags are supported on a seat of wood or
metal having an opening in the centre corresponding with those of the communicating
cocks and bags. The bags are made of india rubber or of any suitable flexible
impermeable fabric, covered with leather or stout canvas which can be still further
strengthened by strong netting. Internally around its orifice the bag is fitted with
a metal washer to which are united bolts or flat headed screws which pass through
the substance of the bags and the upper flange of the communicating cocks and are
tightened up by nuts, leather or other washers being interposed, if thought necessary,
in front of the nuts to prevent any escape of air. The platforms that are placed
upon the bags are secured to the lower ends of connecting rods. There are a few
small holes to give passage to the ambiant air which would otherwise offer a serious
resistance to the rapidity of the movement. The connecting rods are attached to the
cranks of the driving shaft. On the driving shaft are toothed cams which by acting
on rollers on the piston rods raise the pistons; or instead of this arrangement any of
the means used for lifting rams for pile driving and other like purposes may be
employed.
To put the machine in work one of the pistons is raised by turning the fly wheels;
the corresponding valve opens and admits air to the cylinder as the piston rises;
when it has reached the desired height the toothed cam leaves the roller on the piston
rod so that the piston being freed falls and forces out the air from the cylinder into
the corresponding bag. This therefore expands and forces up the platform attached
to the connecting rod which therefore imparts rotary motion to the driving shaft. At
the same time the teeth of the cam belonging to the other piston successively take
under the rollers of this piston and lift it while the first platform is being forced up.
Then the second piston being released in its turn produces a second impulse which has
the effect of lifting the first piston and so on. The result is an alternating or
reciprocating movement of the piston and a continuous rotary motion of the driving
shaft.
By fitting a ratchet wheel and paul to the driving shaft or by adopting other
equivalent means one of the pistons when the machine is stopped can be held at the
top of its stroke so that when freed it will by its descent serve to again start the
machine.

page_text: I THOMAS CHARLES BOUTET, of 1 Boulevard St. Denis, Paris, France, Engineer,
do hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
It is known that every pressure exerted upon a gas or a liquid is imparted with a
proportional power to the surface to which it is transmitted; it is upon this law which
proceeds from Pascal's principle and upon the laws relating to the fall of bodies that
my new motor is based.
The principle upon which my motor is constructed is as follows:-
A piston in rising draws air into its barrel or cylinder through a valve at the
bottom of the said cylinder; the cylinder is also in communication by a pipe at its
lower part with an expanding and collapsing vessel or bag mounted upon a seat which
is formed with an opening in the centre corresponding with that of the pipe and of the
bag. Upon the bag is placed a table or platform of wood or metal for the reception
of weights. The apparatus being thus arranged if the piston be allowed to fall freely,
the pressure exerted by its own weight will force out the air from the cylinder or
barrel into the bag and will expand or distend this latter, thereby raising the platform
with a power which will be multiplied in proportion to the relation of the surfaces of
the section of the piston and of the bag; and this power will be increased by the fall
of the piston. (Law of the fall of heavy bodies.)
Having explained the principle upon which my motor is based I will proceed to
describe its construction. Figure 1 is a side elevation of the motor, Figure 2 a front
elevation partly in section and Figure 3 is a transverse section. The motor is double
acting being composed of two apparatus operating as above described and coupled
together so that the pistons and bags work alternately. A is a frame or platform
barrels
which supports the whole of the apparatus. B, B are two cylinders or pump
mounted on the platform A. These cylinders should be bored and polished for their
whole length in order to avoid friction and escape of air. C, C are suction valves
fitted in special chambers at the bottom of each cylinder B so that said valves as well
as the bottom of the cylinders can be examined and cleaned without interfering with
the pistons. D,D are the pistons; they are of iron or steel, turned and polished with
care; they may be made hollow and filled with lead in order to increase their weight.
The piston rods are provided with rollers to reduce friction. These friction rollers
are covered with leather so as to soften the blow of the teeth of cams which raise the
pistons. E, E are pipes of metal, leather or india-rubber or other impermeable
material which put the lower parts of the cylinders B, B in communication with the
respective motor bags. F, F are cocks for opening or more or less shutting off this
communication. Pointers or indicators G on the keys of the cocks F, F and
moving over a graduated arc H of a circle allow of the speed of the motor being
regulated to a nicety. I, I are cocks for the escape, or in case of need, for the taking

page_text: in, of air, and these cocks may be fitted with whistles. K, K are the motor bags;
they are supported on seats J of wood or metal having an opening in the centre
corresponding with those of the cocks F, F and of the bags K, K. The bags are
made of india rubber or of any suitable flexible impermeable fabric, covered with
leather or stout canvas which can be still further strengthened by strong netting.
Internally around its orifice the bag is fitted with a metal washer to which are united
bolts or flat headed screws which pass through the substance of the bags and the
upper flange of the communicating cocks and are tightened up by nuts, leather or
other washers being interposed, if thought necessary, in front of the nuts to prevent
any escape of air. L, L are the platforms that are placed upon the bags K, K, they
are secured to the lower ends of connecting rods M, M. There are a few small holes
in the platforms L or in the bags to give passage to the ambiant air which would
otherwise offer a serious resistance to the rapidity of the movement. The connecting
rods are attached to the cranks of the shaft O. P, P are standards carrying
bearings Q, Q for the shaft O. N N are rollers or pulleys to guide the 'rods N¹ with
which the rods M, M are connected and to reduce friction. R, R are toothed cams on
the shaft O which by acting on rollers on the rods of the pistons D.raise the pistons; or
instead of this arrangement any of the means used for lifting rams for pile, driving
and other like purposes may be employed. S, S are pulleys for transmitting motion
from the shaft O. T, Tare fly wheels.
To put the machine in work one of the pistons D is raised by turning the fly
wheels T; the corresponding valve C opens and admits air to the cylinder B as the
piston rises; when the piston has reached the desired height the toothed cam R leaves
the roller on the piston rod so that the piston D being freed falls and forces out the
air from the cylinder B through the pipe E and cock Finto the corresponding bag K.
This therefore expands and forces up the platform L attached to the connecting
rod M which consequently imparts rotary motion to the shaft O. At the same time
the teeth of the cam R belonging to the other piston D successively take under the rollers
of the rod of this piston and lift it while the first platform L is being forced up. Then
the second piston being released in its turn produces a second impulse which has the
effect of lifting the first piston and so on. The result is an alternating or reciprocating
movement of the piston and a continuous rotary motion of the driving shaft.
By fitting a ratchet wheel and paul to the shaft O or by adopting other equivalent
means one of the pistons when the machine is stopped can be held at the top of its
stroke so that when freed it will by its descent serve to again start the machine.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, 1 declare that what
1 claim is :-
The motor operated by gravity and air pressure hereinbefore described and
represented in the annexed drawings.
