Year: 1875

page_text: LETTERS PATENT to Pedro Gamboni, of Harley Street, in the County
of Middlesex, for the Invention of "IMPROVEMENTS IN AND ADDITIONS
TO MOTIVE-POWER MACHINES."
Sealed the 9th June 1876, and dated the 14th December 1875.
PROVISIONAL SPECIFICATION left by the said Pedro Gamboni at the
Office of the Commissioners of Patents, with his Petition, on the
14th December 1875. ..
I, PEDRO GAMBONI, of Harley Street, in the County of Middlesex,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN AND ADDITIONS TO MOTIVE-POWER MACHINES," to be as follows:-
The first part of my Invention relates to additional apparatus to be
fixed to my machine, as patented on the 17th day of July 1873,
No. 2469, by which I can maintain a regular and continuous action
for giving off the necessary power to machinery for commercial
nurnoses.

page_text: expansion of the air during the rotation of the machine, the air and the
liquid being within arms and bags on the periphery of a drum, which,
as it rotates, causes a displacement of both agents, and a reaction upon
each other for maintaining the motion.
I have found in practice that my machine, as therein described, is
limited in its power-giving properties, and for the purpose of increasing
them I arrange in connection therewith a drum in which a series of
weights are arranged to move to [and from the periphery as the drum
rotates. These weights, preferably of the roller kind, are connected in
pairs, and as one of each pair is forced inwards or towards the periphery
of the drum the other of the pair is pushed farther away, and in such a
manner that it shall act as a lever to move round in a circle and draw
the drum with it, and thus act as a motive power to keep the mechanism
moving.
The roller weights, as they fall in succession, come into contact with
a plate, the upper part of which is of curved form for the rollers to ride
up and take a position near the periphery until they reach the position
for falling again. The roller weights are lifted as they strike against
the plate by the expansion of an air bag, which takes a position
directly under the weight as it falls, and partakes of the expansion at
that moment.
Instead of the air expansion bags being caused to lift the weights in
succession the pistons or other equivalent appliances referred to in the
former Specification can be used, or a simple lever appliance can be
worked by hand, and a spring can be employed in conjunction to retain
the weights temporarily in the raised position.
The apparatus can be used independently of the machinery described
in my former Patent as a power-giving apparatus, a counterpoise lift
lever being used to raise the rollers or weights.

filed by the said Pedro Gamboni in the Great Seal Patent Office
on the 14th June 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PEDRO
GAMBONI, of Harley Street, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of December, in the
year 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, administrators, 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 AND ADDITIONS TO MOTIVE-POWER MACHINES," 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 of the said Invention, 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 imme-
diately 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 :-
My Invention relates to improvements in and additions to motive-
power machines, whereby I can maintain a regular and continuous
action for giving off the necessary power to machinery for commercial
purposes.
In the Specification of my former Patent, No. 2469/7., I describe a
compression of air by a fallen body of liquid, and the replacing of the

page_text: liquid by the expansion of the air during the rotation of the machine,
the air and the liquid being within arms and bags on the periphery of a
drum, which as it rotates causes a displacement of both agents, and a
reaction upon each other for maintaining the motion.
I have found in practice that my machine, as therein described, is
limited in its power-giving properties, and for the purpose of increasing
them I arrange in connection therewith a drum in which a series of
weights are arranged to move to and from the periphery as the drum
rotates. These weights, preferably of the roller kind, are connected in
pairs, and as one of each pair is forced inwards or towards the periphery
of the drum the other of the pair is pushed farther away, and in such a
manner that it shall act as a lever to move round in a circle and draw
the drum with it, and thus act as a motive power to keep the mechanism
moving..
up
The roller weights, as they fall in succession, come into contact with
a plate, the upper part of which is of curved form for the rollers to ride
and take a position near the periphery until they reach the position
for falling again. The roller weights are lifted as they strike against the
plate by the expansion of an air bag, which takes a position directly
under the weight as it falls and partakes of the expansion at that
moment.
The construction and action of my improved apparatus, either as an
apparatus in itself or as an auxiliary or addition to my Invention referred
to in my former Patent, will be well understood by the following descrip-
tion with reference to the annexed Drawings.
A is a disc or frame mounted upon a crank or other shaft B supported
by standards C, C, between which the disc or frame is free to rotate ;
D, D, are ears or guides upon the disc frame, up and down or along
which rods E, E, are free to move, the rods having rollers F, F, on their
outer ends, and forming the weights which cause the rotation of the
frame by a change of position and alteration of leverage by being pushed
out from the periphery of the frame while approaching and in passing
the top portion of the circle round which the weights and the frame travel.
The roller weights, in approaching the lowest point of the circle, come.
into contact with a lever G having a fulcrum at H, and capable of being
depressed to ease the concussion, the depression of the lever taking effect.
upon a cushion of air enclosed in a bag I, which reacts when the roller
has passed its lowest vertical point, and exerts a pressure upwards upon.

page_text: the roller, forcing it into a race J up which it rolls, the opposite roller
weight of the pair in this position excrting its leverage in full force in
travelling downwards until it bears upon the lever bar G, and gets pushed
upwards again, the leverage of the extended roller weight of the other
pair which then falls maintaining a regular rotation of the crank or other
shaft B.
Figure 2 represents a modification of the foregoing, in which the
inward travel of the vessels F, F, containing liquid and air respectively,
as also the flow of the liquid and the air from one vessel to the other
are governed by counterweights K, K. The vessels and the counter-
weights are connected by chains L, L, passing over rollers L', which
counterweights fall as the vessels F, F, become extended and charged
with air, and in order to put them into position for exerting power.
Each vessel contains an air bag, which becomes compressed by the
inflow of water, the air passing into and through the centre shaft, and
down to the cylinder N by the port P, and finding an exit by the port Q.
Each air bag at intervals is open to the atmosphere, the aperture
being closed by a valve at other times.
The apparatus shown in Figure 2 can be modified in shape, and be
caused to act in an oscillatory manner.
And 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 construction and arrangement of the apparatus described and
shown at Figure 1 of the annexed Drawings, as and for the purpose set
forth.
Secondly. I claim the modification shewn in Figure 2 of the annexed
Drawings when constructed and employed as and for the purpose
described.
In witness whereof, I, the said Pedro Gamboni, have hereunto set
my hand and seal, this Fourteenth day of June, One thousand
eight hundred and seventy-six.
