PROVISIONAL SPECIFICATION.
Improvements in Smoothing Irons.
We, CHARLES LLOYD BRAITHWAITE and EDWARD O'BRIEN, of the Firm of Isaac
Braithwaite and Son, of Kendal, in the County of Westmoreland, Merchants and
Engineers, do hereby declare the nature of this invention to be as follows:-
This invention relates primarily to gas heated smoothing irons but may also
be applied to other irons internally heated.
The sole of the iron is the only part thereof that requires to be heated but a
considerable amount of the heat is conducted therefrom to the sides where it is
lost by radiation and the upper part of the iron unnecessarily heated. The object
of our present invention is to prevent this and consists essentially in constructing
the iron with an insulator of non-conducting material placed between the sole
and the sides or other part of the iron.
In carrying out the invention we construct or build up the iron with the sole
and the sides or body part of separate pieces secured or connected by screws or
bolts and these we separate by an insulator or layer of non-conducting material
such as asbestos, tape or cord or other suitable non-combustible material.
By this means the sole is maintained at a more uniform temperature the sides
and cover are kept cooler loss by radiation is less and the consumption of gas
is reduced.

Improvements in Smoothing irons.
We, CHARLES LLOYD BRAITHWAITE and EDWARD O'BRIEN, of the Firm of Isaac
Braithwaite and Son, of Kendal, in the County of Westmoreland, Merchants and
Engineers, 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 relates primarily to gas heated smoothing irons but may also
be applied to other irons internally heated.
The sole of the iron is the only part thereof that requires to be heated but in
irons as usually constructed a considerable amount of the heat is conducted there-
from to the sides where it is lost by radiation and the upper part of the iron

page_text: unnecessarily heated. The object of our present invention is to prevent this and
consists essentially in constructing the iron with an insulator of non-conducting
material placed between the sole and the sides or other part of the iron.
It will be fully described with reference to the accompanying drawings in
which as an example a gas heated iron is illustrated.
Fig. 1. Side elevation.
Fig. 2. Longitudinal section.
Fig. 3. Transverse section.
We construct or build up the iron with the sole A of a separate piece or separate
from the body or sides B, the two parts A and B being secured or connected by
bolts or screws a. The top C may be formed in one piece with or separate from
the sides B as desired or found convenient.
Between the bottom or sole A and the sides or body B is placed an insulating
strip or layer b of non-conducting material such as asbestos tape or cord, or other
suitable material.
The lid or cover D is also insulated by a non-conductor d.
The burner E is of any suitable or usual construction preferably both for the
inlet of gas and air and the exhaust of the waste products of combustion. The
invention may, however, be applied to any class of internal combustion or inter-
nally heated smoothing iron.
By this invention the sole is maintained at a more uniform temperature, the
sides and cover are kept cooler, loss by radiation is less, and the consumption
of gas is reduced.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. A smoothing iron constructed with an insulator such as asbestos between
the sole and body, substantially as and for the purpose described.
2. A smoothing iron having the several parts constructed and arranged in com-
bination, substantially as described and shown.
