Improvements in Apparatus for use in Systems of Electrical
Distribution of Heating Currents.
I, GEORGE DEXTER BURTON, a citizen of the United States of America,
residing at 194 Washington Street, Boston, in the County of Suffolk and State of
Massachusetts, United States of America, Inventor and Car Builder, do hereby
declare the nature of my invention for IMPROVEMENTS IN SYSTEMS OF ELECTRICAL
DISTRIBUTION OF HEATING CURRENTS, and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
The object of this invention is to distribute heating currents of electricity of
different volumes for heating metals for forging or other purposes.
The drawing represents a plan of an apparatus embodying this improved system
of electrical distribution.
The positive ring 10 and negative ring 11 of an electric current converter_are
disposed in different planes, one above the other. This converter is connected, in
any suitable manner, with a suitable source of electricity, such as an alternating
current dynamo, from which it receives the current to be converted. These rings
are composed of copper, or other suitable conductive material, and provided
with bosses 12 and 13. Flanged sockets 14 and 15 screw-threaded on their
interior are attached to the bosses 12 and 13 by bolts 16 and provided with
adjustable sockets 17 and 18 screw-threaded on their exterior to fit the
sockets 14 and 15.
Conducting rods 20 and 21, composed of copper or other suitable material, are
inserted at their inner ends in the adjustable sockets 17 and 18.
Adjustable clamps 30 and 31, composed of conducting material are adjustable on
the conductors 20 and 21, and wires or cables 40 and 41, connected with said clamps,
serve to conduct the current to an electric heater 50.
Similar adjustable clamps 32 and 33 are also disposed on said rods 20 and 21,
and conductors 42 and 43 connect said clamps 32 and 33 with another electric
heater 60, which latter heater is represented in connection with a drop forging
machine.
Adjustable clamps 34 and 35 are also disposed on the conducting rods 20 and 21,
and electric conductors or cables 44 and 45 connect said clamps with another electric
heater 70, which is represented in the drawings in connection with a roll forging
machine.
Rheostats 80 are interposed in the branch circuits leading to the different machines
or heaters.
The thimbles 17 and 18 may be removed and similar thimbles having different
diameters adapted to conducting rods of different sizes may be inserted.
This apparatus enables the electric current to be distributed to different machines
and regulated to suit the requirements of each.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In an apparatus for distributing electric currents for heating purposes,
the combination of an electric converter, conducting rods extending therefrom,
adjustable clamps on said conducting rods, conductors leading from said clamps
to different electric heaters, and rheostats disposed in the branch circuits of
the heaters.
2. In an apparatus for distributing electric currents for heating purposes, the

page_text: combination of converter rings provided with fixed sockets, adjustable sockets
in said fixed sockets, and conducting rods extending from said adjustable sockets.
