I, JEAN BAPTISTE DENIS 6, Frith Street, Soho Square, London, Clock Maker, do
hereby declare the nature of this invention to be as follows:-
My Invention relates to electric motors of the ring armature type, suitable for a
small or high power. The motor hereinafter described is adapted for mining purposes
and may work vertically or in any other position.
The machine is constructed as follows:-
The motor proper is of annular form and is composed of sections in each of which
are two wheels made of soft iron or smooth steel; these wheels are constructed of a
series of U's of soft iron or smooth steel.
The exterior part of the interior wheel has teeth varying in numbers from 8, 16,
32, 64, 128 upwards always doubling the amount; encircling this wheel is another of
the same number of teeth as the interior wheel, but having its teeth on the interior
part, which teeth are about of an inch in thickness, and the distance between each
tooth is about an inch. The interior wheel is placed in the exterior one and carries
upon its outer face a spindle which causes it to rotate in the Exterior wheel, the latter
however does not rotate. The teeth of the interior wheels should be as near as
possible to the teeth of the exterior wheel without touching.
Bobbins are placed in the interior of each of the U formed pieces of soft iron or
steel, the same number of bobbins being applied to each wheel, as also the same
number of coils and the wire employed should be as fine as possible, without being
wound with coloured silk.
The induction wire of all the bobbins is as thick as all the wires together of each
wheel.
The induction wires of the interior of the bobbines of both wheels are soldered and
take the current from the same toothed wheels which I term "distributing wheels."
Each piece of wire from the exterior part of the bobbins must also be soldered to

page_text: an induction wire; the latter after being divided in two parts and bringing the intro-
duction current to all the bobbins, rojoins at the negative pole.
When it is desired to obtain greater power without increasing the diameter of the
machine and thereby the number of teeth of the interior and exterior wheels, it will
be necessary to multiply the number of sections, seeing that the current is transferred
from one section to another by the "distributing wheels" which prevent the destruc-
tion of the wire.
When there are several sections working together there is only one which receives
the current at the same time and by this means any desired power may be obtained.
The sections are superposed one above the other and are separated by any appro-
priate isolating body of about an inch in thickness.
The teeth of the interior wheels must be in the same proportion as those of the
exterior wheels, by which means the teeth may be further apart without removing the
tension of the magnet, as the number of sections vary according to the diameter.
The interior wheels of each section must be superposed in such manner that the
teeth are presented between those of the wheel of the under section.
The device according to my invention is applicable as a motive force for small
conveyance, such as perambulators invalids' chairs, bicycles, tricycles and so forth.
Referring to the accompanying sheet of drawings.
F. The box of the wheel must be isolated from the wheel by something not
metallic.
G. A ball to change or to stop the motion of the machine by hand.
H. A wheel that makes the Governor P move.
I. A pinion commanding the wheel on which the cables are fixed to raise and lower
the pails.
J. A lever to change the movement or to stop it. This lever rests upon a sector
furnished with 3 notches. The right notch to turn to the right; the left notch to
turn to the left; and the middle notch to stop the movement.
K. A spring to hold the lever firmly.
rise
M. A wire to raise the current by the Governor, or to stop the current according
to the swiftness of the motor.
L. A wire for the current to pass from the distributing wheel while the change of
movement takes place, one or the other of the pails emptying itself.
N. Isolating Pivot.
O. Emptying pails.
P. The Governors.
Q. Supports of the axle of the motor.
R. Irons that cause the change of movement of the machine by the pails them-
selves by returning the current back.
S. Hooks which cause the pails to empty themselves when they reach a certain
height.
T. A float that causes the movement when the float is at the top of the stopping
point U, and stops the movement when the float is at the bottom stopping point U.
V. A spring that keeps the floater raised or lowered so as to act or not to act upon
the current. The motor can be used for other purposes than for raising water. It
can be applied to tramways, on board ship and as a motive power in workshops.
APPLICATION OF THE ELECTRIC MACHINE.
For pumping of the water the machine commands itself. It stops when there is no
more water and is put in motion again without the aid of a Mechanic.
APPLICATION OF THE ELECTRIC MACHINE TO TRAMWAYS.
The motive power is fixed under the car and acts on the axle that turns the wheels,
one wheel turns freely and is not fixed on the axle. This wheel enables the cart to
pass through sharp curves and prevents its leaving the rails. The car is thus driven
by an Engineer instead of a coachman.

page_text: AGRICULTURE.
To threshing machines the motive power may be applied in several ways. The
machine may become the motive power, or the motive power may be placed at the
end of the shaft, the same motive power placed at the end of the shaft may be applied
to mowing, haymaking and all agricultural implements.

page_text: 1, JEAN BAPTISTE DENIS of 6, Titchfield Street, Soho Square, London, Watchmaker,
do hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The electric motor in accordance with my Invention is of the ring armature type
and is applicable as a motive force for sewing machines, perambulators and the like,
or may be employed in connection with suitable machinery for mining purposes, or
indeed for any other work where a high or small power is required.
In order that my Invention may be better understood I have illustrated it in the
drawing left with the Provisional Specification; like letters of reference being
employed to denote corresponding parts throughout the several figures.
The electric motor according to my Invention is composed of two, four or more
annular wheels, each two forming a section and placed one within the other. The
said annular wheels are formed of a series of U-shaped pieces of untempered steel, in
each of which U shaped pieces is adapted a number of bobbins. The interior of the
exterior annulas is serrated, the number of teeth varying, by always doubling the
number, from eight upwards. In the interior of the said exterior annular wheel is a
similar wheel composed of a series of U shaped pieces of untempered steel in each of
which is adapted a bobbin as in the case with the exterior wheel. The exterior side
of each of the said U formed pieces being likewise serrated and has the same number
of teeth as the exterior wheel, the distance apart of each tooth being half an inch
and the thickness of the teeth about one eighth of an inch. Adapted to the interior
annular wheel is a driving shaft, which permits the said Interior wheel to rotate in
the exterior annulas, which latter is stationary. In the rotation of the said annular
wheel, the serrations on the same should come as near as possible to, without making
contact with those on the exterior annulas or wheel. The number of bobbins and coils
and the length of wire are alike in both wheels, in other words the exterior and
interior annular wheels do not differ in any respect but in that of the diameter.
In the construction of the bobbins employed in connection with the electric motor
according to my Invention and which bobbins are placed in the series of U shaped
pieces of untempered steel of which the said annular wheels are composed I prefer
to employ very fine wire, covered with the best non colored silk. The end of each
wire of the interior part of each bobbin is soldered to a wire, hereinafter termed the
introduction wire joining the "distributing" wheel and dividing the current into two
parts. The said introduction wire is as thick as all the wires together of the several
bobbines of one wheel. The end of each wire of the exterior part of each bobbin
must also be soldered, but to a wire hereinafter termed the "leading off" wire, this
wire must likewise he of the same thickness as all the wires together of the bobbin

page_text: of the other wheel. Both these wires for the introduction and leading off of the
currents rejoin at the pole negative.
When it is desired to obtain great power, without increasing the diameter of the
annular wheels aforesaid in proportion to the number of teeth, I multiply the sections,
by which means I am enabled to obtain a strong current, and in order to prevent the
destruction of the wires I transfer the current alternatively from one section to
another by means of the "distributing" wheels. When their are several sections
working together, one only receives the current, by which means I am enabled to
obtain any desired power. The said sections are superposed, and isolated by any
appropriate matter; the distance between each section being about half an inch. The
exterior and interior wheels are sealed with any isolating matter. The number of
sections varies according to the diameter of the annular wheels, the teeth of which
may thus be placed in a different position relatively to those of the corresponding
wheel without deplacing the magnetic tension. The teeth of the interior wheels are
placed opposite to those of the exterior wheel and this arrangement or disposition of
the teeth is followed throughout the whole of the superposed sections.
The motor in accordance with my Invention may be advantageously employed as a
motive force for trycicles, Invalids perambulators and the like where a small current
only would be required. In the construction of motors for such purposes I prefer to
employ fine platina wire covered with the best non colored silk. The wire employed
for the construction of the motor in accordance with my Invention must not be pulled
or drawn out in the process of covering them with the silk or in winding them on
the bobbins.
The diameter of the motor should be as large as possible, and in order to obtain
great power with a small current the numerous bobbins should be constructed of
steel. When larger bobbins are intended to be employed multiplied wires are used,
covered with the best non colored silk, I prefer to place the said wires side by side
without twisting them and thus form a solid cable; the number of wires employed
must be 7. 14. 19. and upwards in proportion, so as to form a circular cable having no
intermediate space. I find that in practice such construction or formation of the wires
give the best results in the motors constructed according to my Invention. The
interior wires of each bobbin are conducted to the introduction wire aforesaid, which
latter is equally as thick in itself as the whole of the wires of the bobbins uniting the
distributing wheel at the positive pole, and the exterior wires of said bobbins are
similarly united to the "leading off" wire which rejoins at the negative pole.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed, I declare that what I claim is :-
The electric motor as herein described and illustrated in the drawing left with
provisional Specification.
