When more than one motor other device

lel orseries. The electrical device shown as
a converter, constructed have described

50 have described the invention its best
and most practicable form which am
aware; but there are other conditions under
which may carried out. For example, in
case the motor andgenerator each has three in-

three terminals common return conductol\
This arrangement will secure similar results to
those attained with ageneratorand motor hav

ductor connecting the said conductors with
the other terminals the generator, set
forth. Such forms of
machines,when adapted this manner my
system, have, however, found less effi

When applied such machines and motors
as have three more induced circuits with a
common electrical joint, the threeor more ter

When motors converters are run in

joined the single wire which completes
both circuits through the generator. The
