Foreign Patent Offices, 18, Ruc de la Chaussée d'Antin, Paris,
France, and 6, Piccadilly, in the County of Middlesex, Patent
Agent, for the Invention of "OBTAINING AND APPLYING ELECTRICITY
AS A MOTIVE POWER."—A communication from Theophile Chutaux,
residing at Fb. Poissonnière. Paris France Engineer Electrician
Sealed the 25th June 1875, and dated the 28th December 1874.
COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition
and Declaration, on the 28th December 1874, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME; I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 18,
Rue de la Chaussée d'Antin, Paris, France, and 6, Piccadilly, in the
County of Middlesex, Patent Agent, send greeting.
WHEREAS I am in possession of an Invention for "OBTAINING AND
APPLYING ELECTRICITY AS A MOTIVE POWER," communicated to me by Theophile
Chutaux, a person resident at F. Poissonnière, Paris, France, Engineer-

page_text: Electrician, and have petitioned Her Majesty to grant unto me, my
executors, administrators, and assigns, Her Royal Letters Patent for
the same, and made solemn Declaration that it is a communication.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do
hereby declare that the following Complete Specification, under my
hand and seal, fully describes and ascertains the nature of the In-
vention, and the manner in which the same is to be performed,
reference being had to the accompanying Drawings, and to the figures
and letters marked thereon, that is to say :—
The Invention relates to a new and improved electric motor, and:
consists (besides the new and improved parts which are used) in the
combination of different well-known electric motors, a combination by
means of which a single series of frame bearings, driving shaft, and
fly wheel will be used, and the series of the same parts which are
required in using each system of motors set up separately are suppressed,
and has the advantage of producing (with a reduced volume) a useful
power much greater than the sum of the useful powers produced by
cach system of clectric motors working separately, the motive power
necessary to overcome the friction and to pass beyond the dead point
of the regulating fly of the new and improved motor being produced
by the combination of all the independent electric motors, otherwisc
the power produced by each of these latter will be absorbed by the
friction and the weight of the fly of each motor working separately.
The Invention is illustrated in the accompanying Drawings in which
Figs. 1, 2, and 3 represent respectively front and side views of the motor.
Similar letters of reference indicato corresponding parts.
The improved motor given here as an example consists in the com-
bination of four electric motors independent one of another (which
could cach act separately) in order to give a rotary motion to the
wheel a, consisting of two flat plates and mounted on the driving
shaft b, on one of the ends of which the driving pulley is keyed, the
said wheel, shaft, and pulley being common to the four motors, and
all parts of the machine being supported on the framework A and the
framo B.
First Motor. This motor consists of soft iron armatures d, greatėr
or less in number, fixed on the circumference of the wheel a which aro
attracted as the wheel revolves successively to the upper and lateral

page_text: its weight, and its position when under no influence can by means of
spiral springs have greater or less amplitudes of oscillation. This
regulation can also be obtained by a computed circular movement of the
points of contact.
Fourth Motor.-This motor consists of one or several clectro-aimants,
through which an electric current passes, coming from a pile distinct
from that of the other motors, and which act through direct attraction on
ono or several soft iron armatures u, connected by a pivoted or flexible
rod V to an excentric x mounted on the end of the driving shaft 6
common to all the motors. By the arrangement of the armatures the 1
attraction takes place when the force of the electro-aimants is the
greatest; and at the greatest length of the lever during the revolution of
the excentric, instead of only being produced when the lever almost has
reached the dead point. Besides the armature & moving in the centre of
a frame y, if this latter is of iron, and if the head of the electro-aimant is 1
broad enough to act on this framic, the attraction of the latter takes
place after that of the armature, as is shown in Fig. 2, and is still very

rollers j, blades, electro-aimants m, and with the wheel a, shaft b, and
pulley c, substantially as above described and set forth.
4thly. The electro-aimants », armature o, catch p, cog wheel 7,
spring 7, in combination with each other and with the wheel a, the
shaft b, and the pulley c, substantially as above described and set
forth.
5thly. The armature u and its frame and their combination with the
electro-aimants t, rod v, excentric x, and with the wheel a, shaft b, and
pulley c, substantially as above described and set forth.
In witness whereof, I, the said Henri Adrien Bonneville, have
hereto set my hand and scal, this Twenty-third day of December,
in the year of our Lord One thousand cight hundred and seventy-
four.
