I, OCTAVIUS MARCH, of 70, Sinclair Road, Kensington, in the County of London,
Electrical Engineer, do hereby declare the nature of this invention to be as
follows:-
:-
This invention for improvements in heating by electricity relates to the method
of heating flat irons, ironing cylinders and other hollow iron or conducting bodies
required to be heated, and consists in making the body of the iron mass to be heated
the secondary circuit of a transformer having a closed magnetic circuit passing
through such hollow body whereby the currents induced directly in the iron mass
serve to heat it.
In one way of carrying out this invention as applied to a calender roll, the
primary circuit is wound on the external part of the core forming the closed
magnetic circuit that is parallel to the roll to be heated, the other parallel part
of the core passing through the centre of the calender roll, The roll rotates around
the central core. In the case of a flat iron, a part of the magnetic core of the
transformer passes through a hole formed in the mass of the iron.

Improvements in Heating by Electricity.
I, OCTAVIUS MARCH, of 70, Sinclair Road, Kensington, in the County of London,
Electrical Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention for improvements in heating by electricity relates to the method

required to be. heated, and consists in making the body of the iron or conducting
mass to be heated, the secondary circuit of a transformer having a closed magnetic
circuit passing through such body whereby the currents induced directly in the

transformer passes through a hole formed intthe mass of the iron.
In the accompanying sheet of illustrative drawings: Fig. 1 is a diagramatic
view showing a calender roll constructed according to this invention, and Figs. 2
and 3 are side and end elevations respectively of a household flat iron. Fig. 4 is
a side elevation of a modified form of Hat iron.
In these views p is the primary conductor or wire, s is the secondary circuit
consisting of a mass of iron or other conducting body that it is desired to heat.
c is the core of the transformer and a closed magnetic circuit.
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. The improved means of heating by electricity by making the body of the iron
or conducting mass to be heated the secondary circuit of a transformer having a
closed magnetic circuit passing through such body.
2. The improvements in heating by electricity substantially as described.
