page_text: LETTERS PATENT to Pedro Gamboni, of No. 8, Harley Street, in the
County of Middlesex, for the Invention of "IMPROVEMENTS IN
MOTIVE-POWER ENGINES OR APPARATUS."
MOTIVE-POWER ENGINES OR APPARATUS.'
وو
PROVISIONAL SPECIFICATION left by the said Pedro Gamboni at the
Office of the Commissioners of Patents, with his Petition, on the
1st September 1875.
I, PEDRO GAMBONI, of No. 8, Harley Street, in the County of
Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS MOTIVE-POWER ENGINES OR APPARATUS," to be as
follows:-
IN
This Invention relates to improvements in motive-power engines or
apparatus, and is based upon the Invention described by me in a previous
Patent, No. 2469, in the year 1873. In the Specification of that Patent
I described a rock beam, into the ends of which a liquid was alternately
permitted to flow when approaching the lowest position of rock, so that

page_text: the accumulative weight of liquid might act upon flexible vessels
charged with air and force such air with the aid of pumps into a flexible
vessel fitted within the opposite end of the rock beam when approaching
its highest point of rock motion.
According to my present Invention I dispense with a rock beam and
employ a wheel or drum in which a series of chambers are formed in its
periphery, such chambers being in pairs, open to each other by properly
arranged passages for the liquid to flow from one to the other as the
wheel rotates. The chambers are provided with flexible bags forming
the covers to such chambers, but which bags are capable of expansion
within the chambers when charged with air, partly from a neighbouring
bag and partly from a pump.
The pump or pumps is or are worked through the intermediation of
suitable gearing from the momentum of the rotating wheel or drum.
The wheel or drum has teeth upon its periphery or in connection with
its axle to gear into a pinion, from the shaft of which mechanism of
any kind can be driven.
In some cases I employ the drum without water chambers, the air
then being caused to flow from one air chamber to another on the
rotation of the drum taking place within a vessel of water provided for
the purpose of compressing the air in the bags as they successively
enter the bags, becoming recharged with air as they leave the water
vessel. Any number of drums or wheels can be used in conjunction,
and the water pressure of one wheel may act upon the air bags of
the other, and vice versa.

page_text: of our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Pedro Gamboni, Her special license that
I, the said Pedro Gamboni, my executors, administrators, and assigns,
or such others as I, the said Pedro Gamboni, my executors, admini-
strators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MOTIVE-
POWER ENGINES OR APPARATUS," upon the condition (amongst others) that
I, the said Pedro Gamboni, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and scals,
should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, 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 the 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, that is to say:-
This Invention relates to improvements in motive-power engines or
apparatus, and is based upon the Invention described by me in a previous
Patent, No. 2469, in the year 1873. In the Specification of that Patent
I described a rock beam, into the ends of which a liquid was alternately
permitted to flow when approaching the lowest position of rock, so that
the accumulative weight of liquid might act upon flexible vessels
charged with air and force such air with the aid of pumps into a flexible
vessel fitted within the opposite end of the rock beam when approaching
its highest point of rock motion.
According to my present Invention I dispense with a rock beam and
employ a wheel or drum, as in the accompanying Drawings, on which a
series of vessels A, A, are fitted around its periphery, the chambers of
such vessels being in pairs, open to each other by pipes B, B, and
properly arranged passages for the liquid to flow from one to the other
as the wheel rotates; the chambers are provided with flexible bags C,

page_text: forming the covers to such chambers, but which bags are capable of
expansion within the chambers when charged with air from the pump
D
through the centre of the shaft E, to which the pipes F, F, are put in
communication in succession as the wheel revolves. The air from the
bags may be divided and a part of it may be directed into a neighbouring
bag and part of it into the pump.
The pump D (or pumps) is worked through the intermediation of
gearing G, H, from the momentum of the rotating wheel or drum. The
wheel or drum has other teeth gearing I upon it to gear into a wheel
from which mechanism of any kind can be driven; J is a fly wheel to
regulate and produce uniform speed of the drum.
In some cases I employ the drum without water chambers, the air
then being caused to flow from one air chamber to another on the
rotation of the drum taking place within a vessel of water, provided for
the purpose of compressing the air in the bags as they successively
enter, the bags becoming recharged with air as they leave the water
vessel. Auy number of drums or wheels can be used in conjunction,
and the water pressure of one wheel may act upon the air bags of the
other, and vice versa.
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 improve-
ments in motive-power engines or apparatus, as herein-before set forth
and shown.
In witness whercof, I, the said Pedro Gamboni, have licrcunto
set my hand and seal, this First day of March, One thousand 2
eight hundred and seventy-six.
