I, HARRY WHITESIDE COOK, of Norwood, in the County of Surrey, a Minor,
do hereby declare the nature of the said Invention for "IMPROVED APPARATUS
FOR OBTAINING MOTIVE POWER APPLICABLE FOR DRIVING MACHINERY, OR FOR OTHER
PURPOSES WHERE A MOTIVE POWER IS REQUIRED," to be as follows:-
My Invention of improved apparatus for obtaining motive power applicable
for driving machinery, or for other purposes where a motive power is required,
has for its object the employment of the axial force of electric coils to produce
a motive power for driving machinery.
The object of my Invention may be obtained by various mechanical
arrangements. I do not, therefore, mean to confine myself to any particular
construction or arrangement of parts so long as the main features of the
Invention are retained. The principle of construction will be understood by
a brief general description of two plans for effecting the desired object. The
axial force of an electric coil, when brought to bear on a core composed of a
bar of soft iron, will attract the latter into the interior of the coil, and it this
attractive force which I intend to utilize and apply. To this end I arrange
any convenient number of core pieces in the form of an endless chain or ring,
which is made to pass through any convenient number of electric coils, which.
are magnetized or electrized by means of suitable batteries in the well-known

page_text: manner. The iron cores are arranged at suitable distances apart, according to
the size and length of the cores, and they are connected together in the form
of a ring or endless chain by some non-magnetic metal or substance; suppose,
for instance, the cores are arranged in the form of an endless chain composed
of alternate links of magnetic and non-magnetic metals; this chain is passed
round and supported by a couple of pullies or prisms, on the axles of which
are mounted toothed wheels or driving pullies, whereby the motion of the
chain pullies or prisms, may be transmitted to any machinery that requires
to be driven. The chain of cores passes through a number of electric coils,
and when a current of electricity is passed through these coils they will
draw forward into them the iron cores of the endless chain, and by so doing
will communicate motion to the chain pullies; commutators or circuit breakers
are adapted to the moveable cores, and are employed for making and breaking
the electric circuit at the proper time as the cores advance. Instead of
arranging the cores in the form of a flexible endless chain as above mentioned,
they may be made into a rigid ring, which will pass through the coils, and
being provided, either externally or internally, as may be found most con-
venient, with teeth, the ring, as it is drawn forward by the attractive axial force
of the coils, may be made to drive toothed gearing, and the motion of the
ring of cores will be thereby transmitted to any machinery that requires to be
driven.
