Improvements in Smoothing Irons.
THE AURORA ENGINEERING JOINT STOCK COMPANY, of 10 Upper
Montagu Street, Montagu Square, in the County of London do hereby declare
the nature of this invention to be as follows:-
This invention relates to smoothing irons and has for its object to provide means
whereby the heating of the same is accelerated, the cooling down of the same
while ironing is slackened and the handle is kept cool.
In the accompanying drawings in all the figures of which the same parts are
indicated by like letters of reference,
Figure 1 is a side elevation of an ordinary smoothing iron mainly of the kind to
which our improvements are applied.
Figure 2 is a plan of the underside of Figure 5.
Figure 3 is a longitudinal section of the smoothing iron having its handle and
handle fittings removed, the section being taken upon the line y-y in Figure 2.
Figure 4 is a transverse section taken upon the line - in Figure 2.
Figure 5 is a longitudinal section of the smoothing iron provided with our non-
conducting means and fitted with our improved handle.

Figure 6 is a sectional view of the modified handle shown in Figure 8.
Figure 7 is an end view of the handle shown in Figure 5 the upright e¹ being
removed.
Figure 8 is an elevation of part of a handle protected in the modified manner
represented in Figure 6.
Figure 9 is an end view of the handle shown in Figure 5.
According to this invention smoothing irons are excavated from above in such a
manner as to produce a kind of dish (a Figures 3 and 4) having a level bottom
and a vertical rim (6 Figures 3 and 4) carried down to the dish bottom. Inwards
and along this rim there is further a trench dug (c Figures 3 and 4) down towards
the bottom of the iron to some distance below the level of the bottom of the dish a.
This dish and trench (a and c Figures 3 and 4) are filled up with any fireproof
material being a bad conductor of heat, for instance asbestos, or any asbestos
compound. Before this material is put in, the handle of the smoothing iron is to
be secured by a screw (½ Figure 5) on to the bottom of the dish a, with inter-
position of like material (d, d, f, f¹ Figure 5) in such a manner as to prevent any
contact taking place between metal and metal. Asbestos tapes (ff Figure 5) of
which the lower ends are screwed down to the bottom of the dish a are brought on
as a lining along the inside of both uprights (e e¹ Figure 5) of the handle in such a
manner as to prevent the hand from coming into contact with the metal of these
uprights, and as to protect the knuckles from being scorched by those uprights.
The gripe of the handle ( Figures 5, 6, 7, 8 and 9) may consist of wrought or cast
ron and is tubular in form with a longitudinal opening (1 Figures 6, 7, and 9) from
end to end. This opening may be at the lower side (l Figure 6) or at the upper
side (Figure 7). In the first place the top ends of the beforementioned asbestos
apes are pressed into the said opening (Figure 6) for the purpose, of. being

page_text: fastened.
In the second case they are connected (fff" Figures 5 and 7) for the
same purpose to the asbestos cloth with which the gripe is lined (i Figures 5, 6,
and 7) the lateral edges of which asbestos cloth are pressed into the beforementioned
slot and fastened therein with a wedge (Figures 6 and 7).
The upper surface of the iron when the dish like excavation a is filled up, may
be coated with any fireproof enamel or paint in order to protect the stuffing
material and for ornamental purposes.
The terms "excavated" "dug" and other similar expressions made use of are to
be taken figuratively as the result they point to may as well be produced by casting
or other means.

Improvements in Smoothing Irons.
We "THE AURORA " ENGINEERING JOINT STOCK COMPANY of No. 10
Upper Montagu Street, Montagu Square, in the County of London 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 to smoothing irons and has for its object to provide means
whereby the heating of the same is accelerated, the cooling down of the same
while ironing is slackened and the handle is kept cool.
We refer to the drawing left with our Provisional Specification in all the
figures of which the same parts are indicated by like reference letters.
Figure 1 is a side elevation of an ordinary smoothing iron mainly of the kind to
which our improvements are applied.
Figure 2 is a plan of the underside of Figure 5.
Figure 3 is a longitudinal section of the smoothing iron having its handle and
handle fittings removed the section being taken upon the line y-y in Figure 2.
Figure 4 is a transverse section taken upon the line in Figure 2.
Figure 5 is a longitudinal section of the smoothing iron provided with our non-
conducting means and fitted with our improved handle.
Figure 6 is a sectional view of the modified handle shown in Figure 8.
Figure 7 is an end view of the handle shown in Figure 5 the upright e' being
removed.
Figure 8 is an elevation of part of a handle protected in the modified manner
represented in Figure 6.
Figure 9 is an end view of the handle shown in Figure 5.
According to this invention smoothing irons are excavated from above in such a
manner as to produce a kind of dish (a Figures 3 and 4) having a level bottom
and a vertical rim (6 Figures 3 and 4) carried down to the dish_bottom.
Inwards
and along this rim there is further a trench dug (c Figures 3 and 4) down towards
the bottom of the iron to some distance below the level of the bottom of the dish a.
This dish and trench (a and c Figures 3 and 4) are filled up with any fireproof
material being a bad conductor of heat for instance asbestos or any asbestos com-
pound. Before this material is put in, the handle of the smoothing iron is to be
secured by a screw (h Figure 5) on to the bottom of the dish a with interposition of
like material (d d' ƒ ƒ¹ Figure 5) in such a manner as to prevent any contact
taking place between metal and metal. Asbestos tapes (ff Figure 5) of which
the lower ends are screwed down to the bottom of the dish a are brought on as a
lining along the inside, or both along the inside and outside of both uprights
(ee Figure 5) of the handle, in such a manner as to prevent the hand from
coming in contact with the metal of those uprights and as to protect the knuckles

page_text: from being scorched by those uprights. The gripe of the handle (k Figures 5, 6,
7, 8 and 9) may consist of wrought or cast iron and is tubular in form with a
longitudinal opening (1 Figures 6, 7 and 9) from end to end. This opening may
be at the lower side ( Figure 6) or at the upper side (Figure 7). In the first
case the top ends of the beforementioned inside asbestos tapes are pressed into the
said opening (f Figure 6) for the purpose of being fastened. In the second case
they are connected (fff" Figures 5 and 7) for the same purpose to the asbestos
cloth with which the gripe is lined (i Figures 5, 6, and 7) the lateral edges of
which asbestos cloth are pressed into the beforementioned slot and fastened therein
with a wedge ( Figures 6 and 7). Conversely the top ends of the asbestos tapes
which may be employed to line the outside of the uprights (e el Figure 5) will in
the first case be connected by the asbestos cloth with which the gripe is lined and
in the second case will be pressed into the longitudinal opening of the tubular
handle for the purpose of being fastened. Instead of depending upon the single
covering of asbestos cloth i for the handle we may employ a double covering of
asbestos cloth with felt or other non-conducting material intervening.
The upper surface of the smoothing iron when the dish like excavation a is filled
up may be coated with any fireproof enamel or paint in order to protect the
stuffing material and for ornamental purposes.

The terms "excavated 'dug" and other similar expressions made use of are to
be taken figuratively as the result they point to may as well be produced by
casting or other means.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is—
1. A smoothing iron interiorly hollowed so as to form an interior core, the
hollow being filled with heat non conducting material all substantially as and for
the purposes herein before described.
2. In a smoothing iron, a handle joined to the base with heat non-conducting
material intervening between the base and the lower extremities of the handle and
clothed with heat non conducting material substantially as and for the purposes
hereinbefore described.
3. In clothing handles of smoothing irons with heat non-conducting material,
fastening the material by means of the slot and wedge substantially as described.
