page_text: LETTERS PATENT to Ignazio de Angelis, of Naples, in the Kingdom of
Italy, Captain in the Army, at present residing at 54, Greek Street,
Soho, in the County of Middlesex, for the Invention of "AN IMPROVED
APPARATUS FOR OBTAINING MOTIVE POWER."-A communication from abroad
PROVISIONAL SPECIFICATION left by the said Ignazio de Angelis at
the Office of the Commissioners of Patents, with his Petition, on the
19th September. 1868.
I, IGNAZIO DE ANGELIS, of Naples, in the Kingdom of Italy, Captain in the
Army, at present residing at 54, Greek Street, Soho, in the County of
Middlesex, do hereby declare the nature of the said Invention for "Ax
IMPROVED APPARATUS FOR OBTAINING MOTIVE POWER," communicated to me
from abroad by the Inventor, Federico Salomone, of Chieti, in Abrizzi, in
the Kingdom of Italy, to be as follows:-
The apparatus for obtaining motive power, to which this Invention relates,
is constructed as follows:-Two drums, each composed of two wheels, are fast
on one axis, and are provided with four weights, which carry arms or levers,
and turn on their axes, but are prevented from turning unduly by stops; on
each arm or lever is a cylinder. The lever or cylinder bears against teeth
formed on a toothed platform on which are the drums. The arms or levers

page_text: project over the axis of the drums without touching it. This arrangement is
exemplified in the accompanying Drawings, in which Figure 1 is a side
elevation, and Figure 2 transverse section. Y, Y, are the two drums fast on
an axis m; each drum consists of two wheels o, and is provided with four
weights N; each weight turns with its axis v, and carries an arm or lever i,
which projects from the drums into the space A. nare stops or abutments
fixed to the wheels o; the weights bear against these stops, and are thereby
prevented from turning completely or too far in one direction, but are free to
turn to the required extent in the opposite direction, or away from or on the
side opposite the stops n. At the end of each arm or lever i is a cylinder e,
which turns on its own axis. This lever i, or cylinder e, bears against the
teeth. The arms i, with their cylinders e, subtend or bridge over the axis m
but do not touch it. The drums are placed on a toothed platform Z, which is
inclined towards the centre, and round which platform are formed the two sets
or rings of teeth z, whereof each tooth of one set corresponds with or stands
opposite the space between every two teeth of the other set. The weights are
so disposed as to be thrown out of equilibrium one immediately after another,
the weight of one drum being so thrown out of equilibrium after the weight of
the other, and the weights of each drum being thrown out of equilibrium
alternately with those of the others, rotary motion is thereby communicated to
the drums on the platform. q are grooves in the platform, in which the
weights work without touching the surfaces of the grooves; p is a projection
on the platform, on which are the teeth z; E is a connecting arm or crank
shaft, in which the axis m works. One mode of stopping the drums is by
brakes t on their outer wheels, worked by a handle X, driving a screw x,
which draws an axis I upward, thereby raising a shaft D, which drives the
brakest against the weights, and holds them fast against the stops n.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Ignazio de Angelis in the Great Seal Patent Office on the
19th March 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, IGNAZIO
DE ANGELIS, of Naples, in the Kingdom of Italy, Captain in the Army, lately
residing temporarily at 54, Greek Street, Soho, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of September, in the year of our Lord

page_text: One thousand eight hundred and sixty-three, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Ignazio de Angelis, Her special licence that I, the
said Ignazio de Angelis, my executors, administrators, and assigns, or
such others as I, the said Ignazio de Angelis, my executors, adminis-
.trators, 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 "AN IMPROVED APPARATUS FOR OBTAINING MOTIVE
POWER," communicated to me from abroad by the Inventor, Federico
Salomone, of Chieti, in Abruzzi, in the Kingdom of Italy, upon the condition
(amongst others) that I, the said Ignazio de Angelis, 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 immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Ignazio de Angelis, 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, as communicated to me, reference being had
to the accompanying Drawings, and to the letters and figures marked thereon,
that is to say -
This Invention relates to an improved apparatus for obtaining. motive
power. This apparatus is constructed in the following mauner :-
Figure 1 of the accompanying Drawings is a plan, and Figure 2 a longi-
tudinal section of an apparatus constructed according to this Invention.
A is a foundation or bed plate, at the centre of which is a socket B, in
which is stepped a shaft C. This shaft is free to revolve in the socket, and
turns at its upper end in a collar B¹, supported in the framework W. D is a
long arm or lever secured at one end to the shaft C, and carrying at its other
end two arms or rods E, E', which depend from it, and carry at their lower
ends bearings, in which an axis F is free to turn. This axis is slightly
inclined. G, G¹, are drums fast on the axis F. Each drum consists of two
discs keyed on the axis F, and also secured together by stays 9, 9. Figures 3,
4, 5, and 6 are detached views of the drums on a larger scale than Figures 1
aud 2. Figure 3 is a vertical section of drum G; Figure 4 is an inside view

page_text: of drum G, or view with one of the faces or discs removed; rigure o, a
-similar view of drum G¹; Figure 6 is a side view of drum G; the outer disc
of each drum is plane, and its inner disc is of a truncated cone shape.
H, H, H, H, are weights suspended within the drum G on axes a, a', a², a³;
H, H, H, H', are similar weights suspended within the drum G¹ on axes
b, b', b, b; the weights are connected to their axes by arms or frame pieces 7, 7.
The faces of these weights correspond in shape to the shape of the disc next
opposite them respectively. The weights are free to move on their axes so as
to fall over or into and out of equilibrium; they are stopped from falling too
far back in their return stroke by the stays g. The weights of the drum G
are placed with respect to the weights of the drum G', in such manner that
they may be said to break joint therewith, as shewn in the Diagram, Figure 7,
in which the full lines represent the weights H, H', H, H³, and the dotted
lines the weights H*, H, H, H', or in other words, the axes a, a¹, a³, a³, are
not in a line with the axes b, b', b³, b³, but are set alternately therewith, or in
.the intervels thereof. The axes of the weights project through the inner discs
of their respective drums into the space between the drums, and carry curved
arms or levers c, c, c, c³, on the outer side of the inner discs of the drums;
there is one such arm or lever to each axis, and therefore four to each drum.
9, 9, are branches by which the arms c, c³, c³, cs, are attached to the axes of the
weights. A weight with its axis and lever is shewn detached in Figures 8, 9,
and 10, whereof Figures 8 and 9 are end views (taken at opposite sides), and
Figure 10 horizontal view, partly in section. n, n, are pins or short cylinders
attached to and projecting from the arms c, c', c², c³. There are three such
pins to each arm; these pins are free to turn on their (horizontal) axes to
reduce friction. Fig. 11 is a plan on an enlarged scale of an arm c. The
arms or levers and pins are thus arranged:-The axes of the two opposite
weights, say, H, H, of the drum G extend rather farther than the axes of the
two intermediate weights H', H³, so that the arms c, c², of the weights H, H³,
though in the same vertical plane with each other are not in the same plane
with the arms c', c³, of the weights H, H³, (which latter two arms are,
however, in the same plane with each other); the two former arms thus
overlap the two latter at the ends; the pins n of the arms c, c², are on the
back surface of those arms or surface nearest the drum, and the pins n of
the arms'c¹³, c³, are on the front surface of these arms, hence the end pins of the
arms c, c², come opposite or confront the end pins of the arms c', c³, see
Diagram, Fig. 12. The arms or levers c, c², c², c³, and pius n of the drum G₁₂
are arranged with respect to each other in like manner. I, 1', are wheels
keyed on the axis F; the wheel I is of longer diameter than the wheel I¹ ;
'

page_text: these wheels run on their respective guide ways K, K'; these guides or ways
are circular or cylindrical concentric platforms supported by standards fixed to
the bed plate A. L is a moveable circular or hollow cylindrical platform
capable of travelling between the platforms K, K', upon an inclined circular
path M formed or raised on the bed plate A. This path is shaped as if a
circular surface were obtained by intersecting a bollow vertical cylinder by an
inclined plane. d. d, are pins or abutments disposed in four concentric circular
rows on the top surface of the platform L; the pins of the row next the inner
edge of the platform are longer than those of the next row, those of this
next or second row longer than those of the third row, and these latter
longer than those of the outermost row or row next the outer edge of the
platform. The pins n abut against the pins d during the rotation of the
drums. N is a rod fixed to and projecting from the platform L; O is a bar
strongly binged at e to the bed plate A, so that it may be raised and depressed
at pleasure; when depressed it fits into a slot f cut in the bed plate A so as to
lie flush with the surface thereof. Of course the four rows of pins d extend
all round the top of platform I, though only a portion of each row is
shewn in Figure 1.
When the apparatus is to be set to work the bar O is raised, and the rod N
brought against the bar O, when the pins n abut against the pins d; they
will force the rod N firmly against this bar O, and the platform L will bo
thereby prevented from moving. As cach weight in turn falls over or drops
out of its equilibrium the drum will be moved round for a portion of its
revolution, and the pins n will abut and bear against the pins d in turn.
The weights being arranged as above described and illustrated in Figure 7,
act without interruption, that is to say, before one weight of one drum has
completed its work a weight of the second drum will have begun its work, so
that one weight of one drum may be said to act alternately with one weight of
tho other, but without interval or intermission as to their combined action;
by these means the dead point is avoided, and continuous and equable rotary
motion produced. The rotary motion so imparted to the drums G, G', will be
communicated by them through their axis F to the wheels I, 1', which will
be driven on their ways K, K', around the shaft C, and the rotary motion so
obtained will be transmitted by the connections E, E, and D to the shaft C,
which will thus be caused to revolve continuously. From this shaft motion
may be transmitted by any ordinary means of applying motive power in any
convenient manner, and for any purpose required.
In order to stop the machine the rod O is depressed so as to clear the bar N,
and the platform L being thus released will be free to turn on its path M,

page_text: whereupon the pins & will cease to present resistance to the pins n, and these
will move the platform L round in a direction contrary to that of the drums
till its bar N is stopped by one of the standards of the platform K, and the
drums G, G, will cease to revolve.
The frame W is not shewn in Figure 1 for the sake of clearness, and the
pins n are not shown in Figure 2.
Having now described the nature of the said Invention, and in what
manner the same may be performed, I declare that I claim, the improved
apparatus for obtaining motive power, arranged and combined substantially as
herein-before described..
In witness whereof, I, the said Ignazio de Angelis, have hereunto set my
hand and seal, this Twenty-sixth day of February, in the year of our
Lord One thousand eight hundred and sixty-four.
