PROVISIONAL SPECIFICATION.
Improvements in Gas-heated Iron for Blocking Straw Hats.
We, SAMUEL HUNT, Telegraph Linesman 57 Dudley Street Luton Beds and
JOSEPH BOYES Manufacturer 69 North Street, Luton Beds do hereby declare the
nature of this invention to be as follows :-
This Iron is heated by a mixture of gas & air. Our improvements consist of a
hollow cast iron chamber, placed in centre of iron, with inlet & outlet tubes for the
passage of the gas & air through the chamber. Our idea is to heat the gas, & air,
before reaching the burners, & so increase, & economize the heat. The iron is heated
at the bottom & the left side by ordinary iron gas-burners. Our idea is to heat the
iron exactly where it is wanted the most, namely:-from the centre of the bottom of
the iron, to the point, & also at the left side of iron.

Manufacturer 69 North Street Luton Beds 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 Iron is heated by a mixture of gas & air. Our improvements consist of a 5
hollow chamber cast in centre of iron with inlet & out-let tubes for the con-
veyance of the gas & air into & out of the chamber. Our idea is to heat the gas
& air before reaching the burners & so increase & economize the heat. It will readily
be seen that when the iron has been at work a little time, the chamber will naturally
become heated, & as a consequence the gas & air passing through it will also become 1
heated.
Fig. 3 represents a plan of the iron & Fig. 1 a side elevation showing ventilation
holes at D. In Fig. 2 the gas & air enter the hollow chamber through G, & after
passing through chamber are conveyed through tube C to burners in H (Fig. 4).
These burners are simply holes drilled in a brass or iron tube, in an oblique position, 1
as shown at L Fig. 4 (in tube H); so as to impinge against left side of iron & so
heat it as well as the bottom; as in blocking some kinds of straw hats the left side
of iron is much used. The gas flows from the burners in long jets, & after being
consumed; the results of the combustion find their way by an opening or chimney
in point of iron, into an upper chamber M (Fig. 4) & out through the vents D in 2
right side of iron.
In Fig. 4, F represents hollow chamber (for heating gas & air). The spaces N & O
run along the entire length of iron & communicate with the upper chamber M by
means of opening in point of iron. The tubes C & H fit in these openings at end of
iron; but do not fill up all the space so that ample room is left for the free ingress 2
of air for ventilation. J in Figs. 12 & 4 represents a connecting socket for con-
venience in removeing & H when necessary. K in Fig. 4 shows a door or cover
which fits on end of iron & seals up the chambers F & M. It is shown in position in
Figs. 1 & 2.
Having now particularly described & ascertained the nature of our said inven- 3
tion, & in what manner the same is to be performed, we declare that what we
claim is
-
(1) The hollow chamber for heating the gas & air before reaching the burners.
The arrangement of tubes for conveying gas & air to burners.
(3) The method of heating the bottom & side of iron by inclined jets or burners
as herein shown.
