within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVED MEANS OF AND
APPARATUS FOR PRODUCING AND MAINTAINING MOTIVE POWER, OR ASSISTING ¦
TO PRODUCE AND MAINTAIN SUCH POWER," upon the condition (amongst
others) that I, the said Pedro Gamboni, my executors or administrators,
by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature

page_text: of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Pedro Gamboni, do hereby declare
the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by
the following statement thereof, reference being had to the Drawings
hereunto annexed, that is to say :—
This Invention relates to means of and apparatus for producing and
assisting to produce and maintain motive power, and consists chiefly in
the employment of double-ended hollow columns or bulbs with a com-
munication between them by a connection for shifting or changing
the pressure of the body of water or other fluid with which the bulbs are
charged from one bulb to the other, the fluid being caused to press upon
in alternate order a flexible body, into and from which air is free to
enter and leave as the columns or bulbs are raised or lowered by any
suitable means. The two bulbs are attached by flexible or fixed tubing
to air receivers and exhausters, from which the cranks or eccentrics of a
machine are actuated.
Any number of the bulbs, connections, and air receivers and exhausters
can be employed in combination in one machine for obtaining the
requisite amount of power.
The Invention will be understood by the aid of the accompanying
Drawings, in which Figure 1 shows in section one form of my apparatus.
A is a frame supporting two cylinders B, B', which are supplied with air
at top and bottom alternately by the pipes C, C¹, from bags D, D¹, which
become compressed alternately by the weight of liquid pressing upon
them, the liquid being hermetically closed within the bulbs E, E¹, and
the connection tube F, by which the liquid flows from one bulb to the
other, as they change their position in the rock movements. The two
bulbs are attached to or form part of a beam or lever G, supported by
trunnions H on the upper part I of the frame A, and they are rocked up
and down by the lever J through its connection with the connecting
rod K of the steam or other power cylinder L, as shown. The two air
cylinders B, B', have pistons whose rods M, M', cause a circular rotatory
movement to be given to the cranks N, N', of a main shaft P, from

page_text: which machinery of any kind can be driven, the speed of rotation being
regulated by the momentum of the fly wheel Q in the usual manner.
The air from the bag D in the view is supposed to have acted through
its pipe C upon the under face of the piston R of the cylinder B, and
also upon the upper face of the piston within the cylinder B¹ in the first
place to raise the piston R towards the top of the cylinder, and in the
second place to push the piston of the cylinder B¹ downwards towards
the bottom of its cylinder, the two cylinders being put into com-
munication by means of the branch pipe S, which is always open. The
air which was previously in the top space of the cylinder B, and in the
bottom space of the cylinder B¹ having been sucked into the bag D¹
through its pipe C¹, and the branch pipe T partly by vacuum and partly
by the action of the pistons of the two cylinders B, B', in their reverse.
movements. By this means the body or column of liquid by flowing
alternately from one bulb to another is caused to exert its weight upon
the bags D, D¹, within them, and so drive the air from them into the
cylinders B, B', for operating the piston R.
Figure 2 represents a similar plan. Here instead of employing pistons
and cylinders I only use two bellows kind of holders B, B¹, for operating
the cranks N, N¹, of the main shaft P. According to this method the
bellows are independent of each other, and have no branch pipes as in
the first method to lead the air from one to the other.
Figure 3 represents a modification of my producer of motive power.
Here the two bulbs E, E', are filled with liquid, and the armis G, G', are
hollow to near the trunnions H, where they are connected by flexible
tubing C, C¹, to the lower ends of cylinders B, B', from the pistons of
which the fly wheel Q is driven through the action of the beam J and
its rod U, as the liquid is admitted alternately into the cylinders B, B¹.
The central portion of the bulb arms has a counterpoise weight V
suspended from it, and as the bulbs B, B¹, are alternately emptied of
their contents the weight V travels through the arc of a circle, and
preponderates on the opposite side to bring the filled bulb downwards to
discharge its contents into the cylinder with which it is in connection,
and to permit of the flexible bag becoming charged with air under the
pressure of the atmosphere, the other bulb which is here shown with a
piston in it in lieu of the flexible bag in its turn being ready for filling
by the pressure of the piston upon the liquid within its cylinder B. The
two pistons in the cylinders B, B³, are thus alternately lifted by a

page_text: pressure of liquid against their under faces, and alternately depressed by
the action of the fly wheel crank N through the rod U and beam J, and
the inflow of air to the bulbs under atmospheric pressure. Morcover,
the liquid columns may be vertical, and fixed so that elastic bodies
charged with compressed air can be alternately submerged in them, and
which air could at will be utilized as a motive power by making it pass
by means of tubes up and down in cylinders and pistons conveniently
situated for that purpose.
Figure 4 represents a method by which the vibrating motion of the
rock lever is produced by solid bodies. In this case two carriages are
mounted upon the lever, and these travel together from and to the ends
by reason of their connection. The ends of the lever have loose
suspended weights attached, which are alternately acted upon by the
lever as the ends rise under the superabundant weight of the opposite
end.
I do not in any way limit myself to the three arrangements of
apparatus shown in the Drawings, as they can be modified according to
the work intended to be performed by the engine, and any number of
bags and bulbs can be caused to rock upon the same or upon different
supporting frames, whereby the compression of air by columns of liquids
can be utilized for producing or assisting to produce motive power, sub-
stantially in the manner described and shown in the Drawings.
Having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, the improved
means of and apparatus for producing and maintaining motive power, or
assisting to produce and maintain such power, as herein-before described
and shown in the annexed Drawings.
In witness whereof, I, the said Pedro Gamboni, have hereunto set
my hand and seal, this Sixth day of January, One thousand eight
