I, LEOPOLD STRAKOSCH of No. 12 Mariahilfer Strasse in the City of Vienna,
Austria, Engineer do hereby declare the nature of my said invention to be as
follows:-
My invention relates to an improved box or sad iron heated by means of spirits of
wine, ordinary spirits or other liquid fuel, the box proper being arranged to turn
around the heating device or the vessel or receptacle for the spirit, said vessel or
receptacle being made of one piece with, or rigidly attached to, the arm of the
handle.
The object of this arrangement is to enable both the upper and the lower surface of
the box to be alternately employed as ironing or smoothing surface for the reason that
whilst one surface is being used for ironing or smoothing purposes, the other surface
is being warmed.
The box proper, consisting of the upper and lower ironing plates and the side and
rear walls, is for curtness sake denominated the box in the following specification.
The heating devico is provided at its forward end with a journal fitting into
a corresponding bearing in the forward end of the box and is at the opposite side or
rear end provided with a spindle to the end of which the vertical arm carrying the
handle is fixed.
The heating device is made with double walls between which non-conducting
material, such as wood, ashes, fossil meal or other bad conductor, is filled, for which
purpose the lower surface or bottom of the heating device can be removed.
This layer of non-conducting material is applied to the lower surface of the heating
device in order to prevent the excessive heating of the fluid in the heating device. A
receptacle is arranged at the extreme rear end of the spindle to the heating device and
is in communication with the said heating device by means of a canal or passage
running through the axis of the said spindle so that the heating device can be filled
from the exterior of the said box, the aforementioned receptacle being closed by means
of an appropriate stopper.
The over-filling of the heating device with fluid is prevented by the upper edge of
the filling or charging receptacle being arranged somewhat lower than the upper

page_text: edge of the receptacle to the heating device, which latter is filled with sponge, cotton
or with incombustible material, such as asbestos, calcined fossil meal or other similar
material to suck up the heating fluid and give off the same as required for heating, said
receptacle being covered with fine wire work or wire gauze. The rear wall of the
box forms the bearing for the spindle to the heating device and is so arranged that it
is held in position by one screw only which when removed will allow of the rear wall
and the entire heating device being withdrawn from the box.
In order to fix the handle in proper position during the ironing or smoothing
operation, a spring bolt is arranged parallel to the arm to which the handle is fixed and
is kept continuously depressed by means of a helical spring so that its lower end gears
into an opening in a lug on the box and thus produces a rigid connection of the parts.
A small door is arranged on suitable hinges in the one side of the box and is held in
closed position by means of an appropriate bolt. The side as well as the rear walls are
provided with perforations so as to admit the quantity of air requisite for the
consumption of the liquid fuel.

page_text: I LEOPOLD STRAKOSCH of No. 12 Mariahilfer Strasse in the City of Vienna,
Austria, Engineer do hereby declare the nature of my Invention for "IMPROVED BOX
OR SAD IRON HEATED BY LIQUID FUEL " and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement:
My invention relates to an improved box or sad iron heated by means of spirits of
wine, ordinary spirits or other liquid fuel, the box proper being arranged to turn
around the heating device or the vessel or receptacle for the spirit, said vessel or
receptacle being made of one piece with, or rigidly attached to the arm of the handle.
The object of this arrangement is to enable both the upper and the lower surface
of the box to be alternately employed as ironing or smoothing surface for the reason
that whilst one surface is being used for ironing or smoothing purposes, the other
surface is being warmed.
In the accompanying drawings, Fig. 1 is a longitudinal section of my improved
box or sad iron.
Fig. 2 is a horizontal section with the heating device partly in top view.
Fig. 3 is a cross section on the line C, D, and,
Fig. 4 is the box or sad iron seen from behind.
The box proper consisting of the upper and lower ironing plates and the side and
rear walls, is for curtness sake denominated the box in the following specification.
The heating device a² is provided at its forward end with a journal a' fitting into
a corresponding bearing in the forward end of the box and is at the opposite side or
rear end provided with a spindle a to the end of which the vertical arin B, carrying
the handle is fixed.
The heating device a² is made with double walls, the space between which, is
filled with non conducting material, such as wood ashes, fossil meal or other bad
conductor, for which purpose the lower surface or bottom 62 of the heating device
can be removed.
This layer of non-conducting material is applied to the lower surface of the heating
device a² in order to prevent the excessive heating of the fluid in the heating device.
A receptacle V is arranged at the extreme rear end of the spindle a to the heating
device and is in communication with the said heating device a² by means of a canal
or passage V running through the axis of the said spindle a so that the heating
device a can be filled from the exterior without having to first open the box g: the
aforementioned receptacle or vessel V being closed by means of an appropriate
stopper V2.
The over-filling of the heating device a² with fluid is prevented by the upper edge
of the charging or filling receptacle V being arranged somewhat lower than the
upper edge of the receptacle to the heating device, which latter is filled with sponge
or cotton, or with incombustible material, such as asbestos, calcined fossil meal, or

page_text: other similar material which serves to suck up the heating fluid and give off the
same as required for heating; the upper part of the heating device is covered with
fine wire work or wire gauze. The part in the rear wall of the box g serves as a
bearing for the spindle a to the heating device and is so arranged that it is held in
position by the screw e which, when removed, will allow of the rear wall and the
entire heating device being withdrawn from and replaced in the box g.
In order to retain the vertical arm B in proper position during the ironing or
smoothing operation, a spring bolt d is arranged in bearings d and d² parallel to the
arm B to which the handle is fixed and is kept continuously depressed by means of
a helical spring fso that its lower end gears into an opening in a lug c on the box g
and thus produces a rigid connection of the parts. A small doors is arranged on
suitable hinges s¹s in the one side of the box and is held in closed position by
means of an appropriate bolt which moves in the brackets 1, of the doors and
which can be pushed backwards and forwards by means of its projection 72. The side
as well as the rear walls of the box yare provided with perforations o, o, so as to admit
the quantity of air requisite for the consumption of the liquid fuel.

is
If it is intended to heat my improved sad or box iron, the spring bolt d is raised
out of lug c and the box g with the door s in opened position is turned upwards, when
the liquid fuel in the receptacle can be readily ignited, after which the box
brought into its original position. Having ignited the fuel in the heating device, the
upper surface of the iron will now be heated in consequence of the heated air flowing
upwards, and when this surface has been sufficiently warmed, the box g is turned on
its axis so that the aforementioned upper surface is located below and can be
employed for ironing or smoothing. During the time this surface is being used
for smoothing purposes, the other surface is located above and is being warmed, so
that both sides of the iron can be alternately employed without interruption.
Having now particularly described the nature of my said invention and in
what manner the same is to be performed, I declare that what I claim is :-
1. An improved box or sad iron heated by liquid fuel, consisting of the box g
provided with two smoothing surfaces, and a heating device such as a² made to
revolve on its axis a, a¹ substantially as and for the purpose set forth and shown
on the accompanying drawings.
2. In the hereinbefore described box or sad iron, the arrangement of a heating
device such as a² suitably journaled at a and a and filled with sponge cotton or
incombustible material, such as asbestos, calcined fossil meal or other similar
material, said heating device having double walls, the space between which is
filled with non-conducting material, such as wood ashes or fossil meal, in com-
bination with the filling receptacle or vessel V attached to vertical arm B, and
communicating with the heating device a² by means of the passage or canal V¹
substantially as and for the purpose set forth and shown on the drawings.
3. The combination, in a box or sad iron heated by liquid fuel, of a vertical
arm, such as B provided with spring bolt d and bearings and d with handle h
substantially as and for the purpose set forth and shown on the accompanying
drawings.
