I, FERDINAND RATH of Pauls Alley Australian Avenue in the City of London
Manufacturer of Gas Irons do hereby declare the nature of my invention for
'IMPROVEMENTS IN HEATING BOX OR SMOOTHING IRONS BY GAS" to be as
follows:-
"
My Invention relates to improvements in heating smoothing irons by gas being
more particularly applicable to gas irons of the character described in the speci-
fication of Letters Patent granted to E. R. Hollands and L. W. Cubitt dated
29th October 1874 N° 3741 and my improvements consist in introducing the gas
and air into gas box irons in such manner that the heat from the gas burner is
greatly increased.
For this purpose I dispense with the hole where the air is admitted and apply an
ordinary Bunsen ball tap to the upper end of the supply pipe to which the flexible
gas tube is connected. This supply pipe is much larger in diameter than the
supply pipe hitherto used. The air and gas supply pipe is continued by another
pipe passage or chamber formed around the iron to conduct the mixed gas and air
to the burners inside the combustion chamber.
Now according to my invention I find that the more distant the burner or
burners are from the gas and air inlet the more intense will be the heat resulting
from the combustion of the mixture of gas and air travelling together from the ball
tap inlet pipe to the burner or burners. The distance between the inlet pipe and
the burners is governed by the size of the pipe or passage and the pressure of the
gas as well as the position of the gas supply in coming from above or below.

Improvements in Heating Box or Smoothing Irons by Gas.
I FERDINAND RATH of Pauls Alley Australian Avenue in the City of London
Manufacturer of Gas Irons do hereby declare the nature of my invention for
"IMPROVEMENTS IN HEATING BOX OR SMOOTHING IRONS BY GAS and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:-
My Invention relates to improvements in heating smoothing irons by gas being
more particularly applicable to gas irons of the character described in the Speci-
fication of Letters Patent granted to E. R. Hollands and L. W. Cubitt dated
29th October 1874 No 3741 and my improvements consist in introducing the gas
and air into gas box irons in such manner that the heat from the gas burner is
greatly increased.
For this purpose I dispense with the hole where the air is admitted in the
arrangement referred to and apply an ordinary Bunsen ball tap to the upper end
of the supply pipe. to which the flexible gas tube is connected. This supply pipe is
much larger in diameter than the supply pipe hitherto used. The air and gas
supply pipe is continued by another pipe passage or chamber formed around the
iron to conduct the mixed gas and air to the burners inside the combustion
chamber.
And in order that my invention may be clearly understood and readily carried
into practice I will proceed to describe the drawings hereto annexed.
DESCRIPTION OF THE DRAWINGS.
•
Figure 1 shows a side elevation and Figure 2 an underside view of my improved
gas iron as I find it advantageous to construct the same.
a is the body of the iron formed with a screw socket a¹ on the side as usual.
Into this socket a tube b is screwed to the upper end of which is screwed a Bunsen
ball tap c, d is the gas supply inlet to which a flexible india rubber tube is
fitted.
->
Heretofore the gas and air for heating the interior of the iron has been intro-
duced and mixed in the socket al.
I now introduce them into the upper end of the tube b which thus forms a
mixing chamber for the gas and air before being burnt, thus insuring a perfect
mixture of the gas and air a more intense heat and more perfect combustion. a² is
a smooth steel plate secured on the bottom of the body a of the iron to form the
smoothing face thereof, in Figure 2 this is removed to show the passages for the
mixture of gas and air to pass to the burners. a3 a³ are additional diagonal
passages formed in the body of the iron by these a more perfect distribution of the
gas and air supplied to the burners a is obtained and all parts of the iron are thus
more evenly heated-e. e. are air passages to supply air to support combustion in
the heating chamber of the iron.
I find that the more distant the burner or burners a are from the gas and air
inlet the more intense will be the heat resulting from the combustion of the

page_text: mixture of gas and air travelling together from the ball tap inlet pipe b, to the
burner or burners a'. The distance between the inlet pipe c and the burners d is
governed by the size of the pipe or passage and the pressure of the gas as well as
the position of the gas supply in coming from above or below.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The improved method of supplying a more perfect mixture of air and gas
combined for heating box or smoothing irons the gas and air being admitted
to the iron by means of a Bunsen ball tap e placed at a distance from the body of
the iron substantially in the manner described and represented in the drawings
annexed.
I also claim the improved arrangement of the passages as a³, to effect a more
perfect distribution of the gas and air to the burners substantially as and for the
purpose hereinbefore described and shown in the drawings.
