County of Middlesex, for the Invention of "IMPROVEMENTS IN Box AND
SMOOTHING IRONS."
Sealed the 21st August 1877, and dated the 28th February 1877
PROVISIONAL SPECIFICATION left by the said Charles John Petherick at
the Office of the Commissioners of Patents on the 28th February 1877.

sex.
This Invention relates to improvements in the application of gas for the purpose.
of heating box and other smoothing irons.
The object of my improvements is so to arrange and construct box and other
smoothing irons that a mixture of gas and atmospheric air may be employed, on the
principle of the Bunsen burner, for heating them, whereby great economy of gas
is effected, increased heating power being developed with perfect cleanliness.
In the interior of the box or smoothing iron a tube is formed, the inner surface:
being perforated with a number of small holes through which the mixture of gas.
and air issues in the form of jets into the interior of the box.
The gas and air supply tube is enlarged at its entrance so as to surround the end
of the tube which supplies the gas which thus draws through an air or Bunsen
burner a current of atmospheric air, the mixture of gas and air being conducted by
the pipe to the nose of the iron where the current is divided in its passage to the
jet holes on each side of the box.
A flexible tube is connected to the gas pipe jet from the supply pipe through the
fore part of the tubular handle, so that the box iron can be readily moved from
place to place when in use with ease and perfect security.
The top plate or cover of the box is slightly raised at one end for the escape of
the products of combustion from the interior of the box through a small valve.

CHARLES JOHN PETHERICK, of Church Road, Islington, in the County of Middle-
sex. "IMPROVEMENTS IN BOX AND SMOOTHING IRONS."
This Invention relates to improvements in the application of gas for the purpose
of heating box and other smoothing irons.
The object of my improvements is so to arrange and construct box and other
smoothing irons that a mixture of gas and atmospheric air may be employed on the
principle of the Bunsen burner for heating them, whereby great economy of gas is
effected, increased heating power being developed, with perfect cleanliness.
And in order that my improvements may be clearly understood and readily put
into practice, I will proceed to describe the Drawings hereto annexed, in which
Figure 1 shows a plan in section, and Figure 2 a perspective view of a box iron
(heated by a mixture of gas and air) arranged and constructed in accordance with
my improvements.
In the interior of the box or smoothing iron A
surface being perforated with a number of small holes
tube a is formed, the inner
through which the mixture
of gas and air issues in the form of jets into the interior of the box, as shown in
Figure 1.
The gas and air supply tube a¹ is enlarged at its entrance a² so as to surround the
end of the tube b which supplies the gas, which thus draws through an air or Bunsen
burner a current of atmospheric air, the mixture of gas and air being conducted by
the pipe a¹ to the nose A¹ of the box iron, where the current is divided in its passage
to the jet holes in the branch pipes a on each side of the box iron A.
A flexible tube c is connected to the gas pipe jet b from the supply pipe through
the fore part of the tubular handle b¹ so that the box iron A can be readily moved
from place to place when in use with ease and perfect security.
The top plate or cover A² of the box iron A is slightly raised at the nose end for
the escape of the products of combustion from the interior of the box through a
small valve or opening H.
My improvements are applicable to box and smoothing irons of various forms and
construction.
Having thus described the nature of my improvements in box and smoothing
irons and the manner of performing or carrying the same into practice, I would
remark that I do not intend to claim separately any of the parts which are well
known and in common use, but what I claim is, the improved arrangement and
construction of box and smoothing irons which are heated by the combustion of a
mixture of gas and air, substantially as herein-before described and represented in
the Drawings annexed.
In witness whereof, I, the said Charles John Petherick, have hereunto set
my hand and seal, this Twenty-seventh day of August, in the year of our
Lord One thousand eight hundred and seventy-seven.
