THOMAS F. PERKINS, OF ATLANTA, TEXAS.
MEANS FOR UTILIZING ELECTRICAL ENERGY.No. 928,214.
Specification of Letters Patent.
Patented J'uly 13, 1909.
Original application filed March 1, 1907, Serial No. 359,984. Divided and this application filed August 15, 1908.
Serial No. 448,719.To all whom it may concern:
Be it known that I, THOMAS F. PERKINS, a
citizen of the United States, residing at At-
lanta, in the county of Cass and State of
5 Texas, have invented a new and useful
Means for Utilizing Electrical Energy, of
which the following is a specification.
This invention has reference to improve-
ments in means for utilizing electrical energy
10 and its object is primarily to utilize in useful
work electrical energy which has heretofore
been to a great extent wasted or dissipated.
This application is a division of an applica-
tion, Serial No. 359,984, filed by. me on 1
15 March 1, 1907, and the present invention
consists in means for utilizing the extra cur-
rent generated by the break in the circuit of
an electro magnetic apparatus having a com-
mutator so that such current will charge a
20 circuit containing translating devices respon-
sive to the energy of the said extra current.
The invention will be best understood from
the following detail description-taken in con-
nection with the accompanying drawings,
25 forming a part of this specification, in which
drawings-
Figure 1. is a diagrammatic representation
of a means for utilizing the extra current, in
accordance with the present invention, said
30 means being electro. magnetic. Figs. 2, 3+
and 4 are diagrammatic representations of
means for carrying out the invention wherein
the extra current is converted into radiant
energy. Fig. 5 is a diagrammatic represen-
35 station of a means. for carrying out the inven-
tion where the extra current is utilized for
the purpose of doing mechanical work. Fig. t
6 is a diagrammatic representation showing
the application of the invention to a distrib-
40 uting system.
The present invention is based upon the
fact that when a charged electric circuit con-
taining electro magnetic translating devices
is broken, there is an extra current produced
45 due to the self induction of the current. Such
currents are usually manifested in a commu-
tator in the form of sparks and various ex-
pedients have been proposed to reduce or
obliterate sparking. The energy of this ex-
50 tra current has been usually allowed to dissi-pate without doing any useful work. By the
present invention the energy of such extra
current is utilized for the production of either
mechanical energy or radiant energy.
In Fig. 1 there is shown a simple type of 55
motor wherein there are indicated two field
magnets 1 and 2, in operative relation to. an
armature 3 mounted upon an armature shaft
4. Mounted upon the shaft 4 is a commu-
tator consisting of two plain rings 5-6 each 60
provided on one edge or face with teeth or
plates 7 which may project to a greater dis-
tance from the axis of the shaft than does the
active face of either of the rings 5 and 6.
The teeth 7 of one ring engage between the 65
teeth 7 of the other ring, and both the rings
and teeth are insulated from each other and
from the shaft. This is a known form of
commutator and needs no special description
or illustration. Bearing upon the ring 5 is a 70
brush 8, and bearing upon the ring 6 is a
brush 9, and in the path of the teeth 7 of
both rings is a brush 10. In the structure
shown in Fig. 1, the brush 8 is connected by
a conductor 11 to one side of a battery 12 or 75
other source of electrical energy, and the
brush 9 is connected by a conductor 13 to the
other side of said battery 12. That side of
the battery which is connected to the brush 8
is also connected by a branch conductor 14 80
to one terminal of the field magnet 1, and
that side of the battery which is connected
to the brush 9 is also connected by a branch
conductor 15 to one side of the field magnet
2. The other terminals of both field mag- 85
nets are connected by a common conductor
16 to the brush 10.
If it be assumed that the brush 10 is upon
a tooth or segment connected to the ring 5,
then the current will flow from the battery 12 90
through the conductor 11 to the brush 8, and
by the brush 10 and conductor 16 to the mag-
net 2 and returning by the conductor 15 to
the other side of the battery 12. Under
these circumstances the magnet 1 is in a 95
dead loop so far as the battery 12 is con-
cerned. However, a circuit may be traced
from the battery 12 by the conductor 14
through the magnet 1 thence to. the magnet 2
and by conductor.15 back to the other side of 100
