page_text: PROVISIONAL SPECIFICATION left by the said Antoine Marie Joseph
Count de Molin at the Office of the Commissioners of Patents, with
"bis Petition, on the 2nd September 1864.
I, ANTOINE MARIE JOSEPH COUNT DE MOLIN, of Paris, France, Gentleman,
do hereby declare the nature of the said Invention for "AN IMPROVED
ELECTRO-MAGNETIC ENGINE," to be as follows:-
The object aimed at in the construction of this improved electro-magnetic
engine is to have each of the electro-magnets of the machine at the moment
the same is to attract its respective armature to be situated at a very small
distance apart from this latter.
7.
For this purpose a suitable number of electro-magnets are fixed vertically
in a concentric manner, at equal distances apart, on a horizontal bed plate
or ring, by preference of brass, cast iron, or other suitable metal or material,
solidly fixed on any suitable frame. In the centre of this ring or circular
plate may be allowed to revolve freely a vertical arbor forming the spindle
axis of and to which is fixed. a. horizontal circular top plate or ring
similar to the one underneath. To the under side of this upper ring.or-top

page_text: plate are fixed a number of armatures corresponding exactly in number and
position with the electro-magnets underneath, in such manner that each
of these latter has its respective armature.. By means of a galvanic battery
suitable connecting wires, pole changers, or current interrupters, and other
similar well-known arrangements, each of the electro-magnets may in its
turn be caused to attract its corresponding armature, by which means a
revolving rolling motion will be imparted to the ring carrying the armatures,
motion similar to that of a top rolling over the ground when at the point of
nearly finishing its revolutions. The revolving motion of the vertical arbor
and upper ring is to serve as a prime mover, and may be transmitted to other
machinery by any suitable means.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Antoine Marie Joseph Count de Molin in the Great Seal
Patent Office on the 2nd March 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANTOINE
MARIE JOSEPH COUNT DE MOLIN, of Paris, France, Gentleman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing, date the Second day of September, in the year of our Lord
One thousand eight hundred and sixty-four, .in the twenty-eighth. year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Antoine Marie Joseph Count de Molin, Her special licence that I,
the said Antoine Marie Joseph' Count de Molin, my executors, adminis-
trators, and assigns, or such others as I, the said Antoine Marie Joseph
Count de Molin, 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 "AN IMPROVED
ELECTRO-MAGNETIC ENGINE," upon the condition (amongst others) that I, the
said Antoine Marie Joseph Count de Molin, my executors or adminis
trators, 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.

page_text: NOW KNOW YE, that I, the said Antoine Marie Joseph Count de Molin;
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:-
The Invention relates to an improved electro-magnetic engine, the leading
principles of which consist, 14, in the particular position in which the
electro-magnets are situated in respect to each other and to. their respective
armatures, whereby constantly but a comparatively very small distance is
left apart between the said armatures and their respective electro-magnets
before these latter become magnetized; and, 2, in the particular wave-like
rolling motion imparted to the parts carrying the said armatures, the said
motion resembling about the rolling of a top on the floor towards the end of
its revolving motion.
In the annexed Drawings, Fig. 1 represents, about one-tenth of the
working scale, an elevation or outside view of my improved electro-magnetic
engine; Fig. 2 represents a plan view of the same taken over the rings
which carry the armatures, and with the frame of the machine removed;
Fig. 3 shows a plan view from underneath, or about one-tenth of the
working scale, of the mode in which the electrical current is made.to
circulate alternately in each of the electro-magnets. In these Figures the
same. letters refer. to corresponding parts, whilst, in order to avoid confusion,
the conducting wires and some other parts represented in Figs. 2 & 3 are left
out in Fig. 1.
The machine consists of a strong frame Z, of wood, cast iron, or other
suitable solid material. On the bed plate I of this frame are securely fixed
concentrically and at equal distances apart a series of electro-magnets A¹,.A²,
.A, A, A, A, A7, &. A³, of equal size and strength. The machine .is
represented in the Drawings with 8 of these electro-magnets, but any other
number exceeding 3 might suit the purpose, though it is preferable there
should be at the least 8 of them. In the centre of the bed plate I is fixed
a small pillar or standard k, on the top of which rests and is allowed to
revolve a steel cone i, forming the lower end of a short arbor M. fixed in the
centre of two rings I' and 13, of brass or any other suitable metal, the inner
ring I being provided with arms ; and a central boss j", whilst the. arma-
5tures B1, B2, B3, B4, B5, B6, B', and B³, fixed against the lower surface of the
rings I & I, connect these latter together. The top m of the arbor M
revolves in the hollow part of a small crank arm M' so as, to form, a ball-
and-socket joint. The crank M¹ is fixed to the lower end of a vertical
shaft N revolving in bearings provided in the cross bars N& N of the

page_text: 3 and
frame. Z, whilst at the top the shaft N. is provided with a fly wheel N³,"
with fast-and-loose pulleys for transmitting the revolving motion of the shaft N.
to any parts to be driven by the machine..
:
From what has been described, and on examining the Drawings, it. will be:
readily understood that as each of the armatures B1, B2, B3, B; B, B, B', B³,
is situated exactly above its respective electro-magnets A'; A, A, A, A,.A%;
A7, A8, if each of the said armatures be attracted in its turn by its respective
electro-magnét, each of the said armatures will in its turn be carried in con-
tact with its respective electro-magnet, and consequently a wave-like.rolling
motion be imparted to the rings. 1' & I about similar to that of.a. top rolling.
over the floor towards the end of its revolving motion.
Various devices might. be resorted to for causing in turn each of the electro-
magnets to be attracted by its respective armature, either merely by the
agency of the electro-magnetic force or by the intervention. also of the .fly
wheel N³.. ว

.1. .
The following arrangement, for instance, might be adopted :-P is a wooden
board fixed in. the. frame. Z, through a hole in the centre of which board
passes the iron arbor N by means of a ring n of ivory, bone, or other suitable
isolating material. The arbor N is kept isolated from a boss n', of brass.or
other suitable metal, provided round. the ring n, both ring and boss n¹
being securely fixed. to the. arbor N by a screw p or other suitable means,
whilst on the boss n¹ is fixed one end of a spring R, of steel or other suitable
elastic metal, the other or free end of which during the revolution of the
arbor N presses on the top of a series of brass plates a, a, a, a, a,a,a,ia³,
fixed on the board P.in a concentric manner round the arbor N. and at equal
alistances apart, the length of the. spring R being such as always to. press
:simultaneously on two succeeding plates, each of which latter is connected
by means of a conducting wire to the wire of the outer bobbin Aª of: its
corresponding electro-magnet, viz., the plate.al to the electro-magnet. A;
the plate a to the electro-magnet A, and so on. On the other hand;
a.spring q, of steel or other suitable elastic metal, is fixed with one end to the
board P, whilst its other or free.end presses against the boss n; the fixed
end of this spring is connected by a wire w to one of the poles of an electric
battery, the other pole of which is connected by a wire w¹ to a spring, or.
conductor w³, to which are connected all the wires 61, 62, 63, 64, 65, 68, 67, 68, of
the bobbins Ab of the electro-magnets. The spring R must be of such
length and curved in such manner that at the very moment its free end leaves:
one of the plates, as for instance, the position of the rings I & I' be such that
the armature B is in close contact with its respective electro-magnet:A
:

page_text: The mode of working of the engine is as follows:-Supposing the
armature B³ to be in close contact with its corresponding electro-magnet A®,
latter, the position of the spring
already demagnetized, viz., the
beginning at this moment to be
the armature B' will.come in close
viz., actually pressing on the top of this
being such that this electro-magnet be
electric current broken, the armature B
attracted by its electro-magnet A, whilst
contact with its electro-magnet A', the spring R will have left the plate a',
and advanced towards the plate a³, continuing during this time to press
against the plate a; the armature B' will now have been attracted and
carried in close contact with its electro-magnet A', and this latter at the
same time become demagnetized by the breaking of its electric circuit,
consequently each of the armatures will in the same manner each in its turn
be carried down and brought in close contact with, viz., to bear on the top of
its respective electro-magnet, and thereby the above-described wave-like
revolving motion imparted to the rings I¹ and I, and by means of the arbor M
a revolving motion transmitted to the shaft or arbor N,.and further, to any
machinery to be driven by the engine.
Having thus described and particularly ascertained the nature of my
Invention, and the manner in which the same is or may be carried into effect,
I would observe in conclusion that I do not confine or restrict myself to the
precise details of the machine above described, as many variations may
be made therefrom without deviating from the principles or main features
of the Invention; but what I consider to be novel and original, and therefore
claim as the Invention secured to me by the herein-before in part recited
Letters Patent, is, the general arrangement, combination of parts, and mode
of working of my electro-motive engine, substantially as has been described
above..
In witness whereof, I, the said Antoine Marie Joseph Count de
Molin, have hereunto set my hand and seal; this Twenty-fifth day
of February, in the year of our Lord One thousand eight hundred
and sixty-five
