BERTIE CHARLES SCOTT, of Parklands, Hassock's Gate, Sussex. "AN IMPROVED
ARRANGEMENT AND CONSTRUCTION OF ELECTRIC-MOTOR, AND APPARATUS IN CON-
NECTION THEREWITH."
The primary object of this Invention is the peculiar arrangement of a series of
electro magnets with their connections, which will give a superior means of oscil-
lating a beam for transmitting power for driving purposes. This part of my
improvements consist in the arrangement of a series of magnets contained within
an arc of about 60° of the circle, or may be in a completed circle, each magnet being
provided with its own bridge of contact, on one side passing to a common return
for all the magnets contained within the arc or circle on the other side.
Before the said arc or circle of magnets a lever arm is arranged in a radial
position, and the course of the current is as follows :-
On the vertical standard or pillar supporting the beam, and near the point or
centre on which such beam oscillates, sliding contact makers are fitted, which are
worked by an arrangement of link motion similar to that of a steam engine slide
valve. The current of electricity passing these contact slides is carried thence by a
flexible wire to a metal strip, which conducts it to two rollers which work the
contact bridges; thus if the lever arm or beam in the first instance oscillates in an
upward direction then the current is reversed by the link motion contacts. The
electro inagnets being then brought into play in an opposite manner the beam or
lever arm oscillates in a downward direction.

page_text: The beam or lever arm oscillating on its centre or pivot, supported on the pillar
above mentioned, communicates its power through the medium of a connecting rod
to a crank carrying or actuating a fly wheel and pulley in the usual manner.
Secondly. The improvements relate to an arrangement of parts in connection
with the batteries designed for regulating the motive power, and consists in con-
structing the battery into any number of divisions, each one of which is represented
by a number on a dial provided with a pointer or handle.
The connections of contact between the battery and the said pointer or handle is
so arranged that when it is turned to any given number on the dial an increase or
decrease of power represented by such number will be transmitted from the battery
to the magnets working the electro motor.
The batteries can be so arranged that a current of "quantity electricity" or
" tension electricity" may be obtained with equal ease.

the said Bertie Charles Scott in the Great Seal Patent Office on the 5th June

"AN IMPROVED ARRANGEMENT AND CONSTRUCTION OF ELECTRIC MOTOR, AND
APPARATUS IN CONNECTION THEREWITH."
The primary object of this Invention is the peculiar arrangement of a series of
electro magnets with their connections, which will give a superior means of oscil-
lating a beam for transmitting power for driving purposes.
This part of my improvements consists in the arrangement of a series of magnets
contained within an arc of about sixty degrees of the circle, or may be in a completed
circle, each magnet or set of magnets in connection being provided with its own
bridge of contact on one side, passing to a common return for all the magnets
contained within the arc or circle on the other side, the said magnets being magnet-
ized by the conveyance of the electric current from the battery along the beam or
beams of the electro-motor, and running connections attached thereto.
Before the said arc or circle of magnets a lever arm carrying an armature is
arranged in a radial position, and the course of the electric, current is as
follows:-
:-
On the vertical standard or pillar supporting the beam, and near the pivot or
centre on which such beam oscillates, contact makers are fitted, which are worked
by a commutator fixed to and revolving with the main shaft of the motor. The
current of electricity passing this commutator is carried thence by rollers, and their
flexible supports to two metal strips communicating with the contact makers, from
which it is conducted by wire to two sliding fingers working the contact bridges;
thus if the current of electricity passing to the magnets in the first instance causes
the lever-arm or beam to oscillate in an upward direction, by reversing the current

page_text: (through the medium of the commutator contacts) the electro magnets will be brought
into play in such a manner as to cause the beam or lever arm to oscillate in a
downward direction.
The said beam or lever arm oscillating on its centre or pivot, supported on the
pillar before mentioned communicates its motion through the medium of a con-
necting rod to a crank carrying or actuating a fly wheel and pulley in the usual
manner to be employed as a stationary engine or for the purposes of locomotion.
Secondly. The improvements relate to an arrangement of parts in connection
with the batteries designed for regulating the motive power, and consists in con-
structing the battery into any number of divisions, each one of. which is represented
by a number on a dial provided with a pointer or handle. The connections of
contact between the battery and the said pointer or handle is so arranged that
when it is turned to any given number on the dial an increase or decrease of power
represented by such number will be transmitted from the battery to the maguets
working the electric motor.
The batteries can be so arranged that a current of "quantity electricity" or
"tension electricity" may be obtained with equal ease.
In order that the Invention may be well understood and explained in detail I
have hereunto annexed a Sheet of Drawings made upon a scale of about one third
simil Inttown of foranen hoins munlad thonALDAN
Fig. 1 represents an end elevation of the improved construction of electric motor;
and Fig. 2 represents a side elevation of the same.
Fig. 3 represents a section through the line v, v, Fig. 2, of the framing or bearer
supporting the electro magnets; and Fig. 4 represents in detail a side and front
elevation of the commutators.
In Figs. 1 and 2 a, a, is the framing or bed plate of the machine, to which is
secured the pillar b; bearings or plumber blocks c, c; and the upright standard or
bracket d, supporting the electric magnets e, e.
The series of magnets e, e, are so arranged as to be contained within an arc of
about sixty degrees of the circle; or such magnets may be contained in a completed
circle, and although a row of single magnets only is shewn in the Drawing as
forming the arc I do not limit myself to that number, as two or more magnets may
be employed when it is desired to obtain an increase of power; and I would here
observe that I avoid the use of large magnets, and use in preference small ones in
increased number, as it is necessary to the effective working of the motor that the
magnets should be saturated instaniously up to their full power. Each magnet of
the arc or circle is provided with its own bridge of contact ƒ on one side, passing to
a common return for all the magnets contained within the arc or circle on the other
side:
In front of the said are or circle of magnets e, e, the beam or lever arm g is
mounted in and supported by the pillar b in such a manner that it may freely
oscillate upon its centre or fulcrum h. The long arm of this lever or beam g is provided
at its end immediately in front of the segmental series of electrio magnets e, c, with an
arinature i, the connection of such lever or beain with the bridges f, f, being
established by means of the fingers k, k. The short arm of the said lever or beam
on the opposite side of its fulcrum h is coupled to the rod l, connecting it with the
crank m keyed on the shaft n. On the shaft n the commutator discs o, o, (seen
enlarged and in detail at Fig. 4) are secured; the conducting portion of these discs
is marked o', and the non-conducting portion is marked o². On the periphery of
the commutator the contact rollers p, p, bears, and through which the electric
current passes (according as one or other of the rollers happen to be on the con-
ducting portion of the discs) onward through the strips of metal q, q, handle », and
conducting wires to the fingers k, k, connected with and working the contact
bridges f, f. By a movement of the handle r actuating the contact inaker ¹ the

page_text: current of electricity passing to the magnets can be directed so as to give the lever-
arm or beam g when starting an upward or downward throw, and so cause the
driving shaft n to revolve in one direction or the other as desired. This reversing
motion acts in manner similar to that of the link gear actuating the slide valves of
a steam engine.
The beam g is so balanced that the weight of the long arm may be equal to that
of the short arm, connecting rod l, and balance weight s¹.
The electric connections and course of the electric current for actuating the beam
through which power is transmitted for driving stationery or locomotive machines.
may be easily understood by the following description and reference to
Drawings:-
The electric current from the battery first passes to the disc of the commutator
marked 1, thence through the running contact rollers p up the strips q, q, to the
contact makers r¹ and handler, from whence it is carried by the wire s and coupling
fingers k, k, working the bridges f direct to the electro magnets e, e, the attractive
force of which, through the medium of the armature i, causes the beam or lever
arm g to oscillate, the motion of which through its connecting rod / causes the crank
shaft n and By wheel pulley u to revolve for transmitting power for driving purposes
in manner as herein before described.
Having now described the nature of my said Invention, together with the manner
of performing the same, I wish it to be distinctly understood in conclusion that
what I claim as new and of my Invention is,-
First. The novel arrangement, combination, employment, and use of a series of
electro magnets and their connections for transmitting power for driving purposes
in manner as herein substantially described, set forth, and fully illustrated in the
Drawings annexed; and
Secondly. The novel arrangement and disposition of battery and dials to be
employed for regulating the power transmitted from the battery to the magnets in
manner as herein substantially described.
In witness whereof, I, the said Bertie Charles Scott, have hereunto set my
hand and seal, this Fourth day of June, in the year of our Lord One
thousand eight hundred and seventy nine.
