PROVISIONAL SPECIFICATION.
Improved Means for Heating Smoothing Irons and Ironing Rollers
for Laundry Use.
I, GEORGE ROBERTSON HISLOP, of the Gas Works, Paisley, in the County
of Renfrew, Engineer and Gas Works Manager, do hereby declare the nature of
this invention to be as follows:-
This invention has for its object to provide simple and efficient means for heating
smoothing irons and ironing rollers or like ironing apparatus as used in laundries
whereby the discharge of poisonous gases into the apartment resulting from the
ordinary mode of heating by the combustion of gas within such irons or rollers is
altogether avoided.
Under the invention the smoothing irons and rollers, which like the ordinary
gas irons and rollers are made hollow, are heated by meaus of a current of super-
beated steam or air or the products of combustion of solid, liquid or gaseous fuel
conveyed by flexible tubing and caused to traverse them at a suitable temperature.
The heated gases or air are forced or drawn through the ironing apparatus by
means of fans or blowers or by the draft induced by a jet or jets of steam, the irons
being hermetically closed and the supply and discharge of the gases being effected
through flexible inetallic tubing suspended from overhead pipes. Provision may
be made for regulating the temperature and the volume of the gases. When steam
or other condensible gas is employed a suitable outlet to the atmosphere may be
provided, but in heating the ironing devices by means of hot air or gaseous pro-
ducts of combustion the air or gases may be circulated continuously by means of
suitable forcing and drawing devices through the irons and the piping, part of
which may be carried through a furnace or may form a superheater. The irons
and rollers may be jacketed or so constructed internally as to provide for leading
the air or gas of higher temperature first in close contact with the side of the shell
forming the ironing surface, and then back as it becomes cooler through a passage
out of direct contact with the ironing surface..
After passing through irons or rollers requiring a high temperature the gases
may be circulated through others requiring a lower temperature or the waste heat
may be utilized by circulating the gases through radiators or other heating
apparatus.

Improved Means for Heating Smoothing Irons and Ironing Rollers.
for Laundry Use.
I, GEORGE ROBERTSON HISLOP, of the Gas Works, Paisley, in the County
of Renfrew, Engineer and Gas Works Manager, 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 has for its object to provide simple and efficient means for heating
smoothing irons and ironing rollers or like ironing apparatus as used in laundries,
whereby the discharge of poisonous gases into the apartment resulting from the
ordinary mode of heating by the combustion of gas or other fuel within such irons
or rollers is altogether avoided.
The invention is illustrated by the accompanying drawings, Figure 1 being an
elevation, Figure 2 a plan, and Figures 3 and 4 part end elevations of the improved
means for heating smoothing irons and ironing rollers for laundry use.
Under the invention the smoothing irons A and rollers, which like the ordinary
gas irons and rollers are made hollow, are heated by means of a current of super-
heated steam or air or the products of combustion of solid, liquid or gaseous fuel
conveyed by flexible metallic tubing B and caused to traverse them at. a suitable
temperature. The heated gases or air are forced or drawn through the ironing
apparatus A by means of fans or blowers or by the draft induced by a jet or jets
of steam, the irons being hermetically closed and the supply and discharge of the
gases being effected through the asbestos. covered flexible metallic tubing B
suspended from overhead pressure and exhaust pipes C, C', similarly covered.
Provision may be made for regulating the temperature and the volume of the
gases. The regulation of the temperature of the heated gases or air forced or
drawn through the pipes to the ironing apparatus is effected by means of apparatus
such as shown on the drawings and which consists of a mercurial gas regulator D
the mercury in which on rising or falling acts on a float D' attached to a lever D'
the other end of which turns a cock D' to admit less or more gas to a heater E
through which the gases or air passes on their way to the ironing apparatus, a
thermometer D being provided to indicate the degree of heat in the heater. The
volume of heated gas or air may be controlled by means of a regulating valve F
connected by means of a pipe G to the pressure pipe C, the spindle of said
regulating valve F being connected so as to act on the throttle valve of the engine I
and govern the action of the pump H. Instead of a steam engine a water wheel
or turbine may be used for actuating the pump. When steam or other condensible
gas is employed a suitable outlet J to the atmosphere may be provided, but in
heating the ironing devices by means of hot air or gaseous products of conibustion
the air or gases may be circulated continuously by means of the pump H or other
suitable forcing and drawing devices through the irons and the piping the whole or
part of which may be carried through the furnace or superheater E. The irons
and rollers may be partitioned, jacketed or so constructed interually as to provide
for leading the air, gas or steam of higher temperature first in close contact with
the side of the shell forming the ironing surface, and then back as it becomes cooler
through a passage or pipe out of direct contact with the ironing surface. Pressure
and vacuum gauges K, L, may be provided to indicate the degree of pressure and
vacuum in the pipes C, C¹.
After passing through irons or rollers requiring a high temperature the gases
may be circulated through others requiring a lower temperature or the waste heat
may be utilized by circulating the gases through radiators or other heating
.apparatus.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. The improved means and apparatus for heating smoothing irons and ironing
rollers for laundry use substantially as described with reference to the accompanying
drawings.
2. The heating of smoothing irons and ironing rollers for laundry use by means
of superheated steam, heated air, or the products of combustion of fuel caused to
circulate through said irons or rollers by flow and return piping the temperature.
and volume of the gases being suitably controlled substantially as described.
3. As means for heating smoothing irons and ironing rollers for laundry use the
combination of a furnace fitted with heating tubes, flow and return piping connecting
these tubes and the irons or rollers and a blower or other device for circulating the
air or gases through the piping and irons or rollers substantially as described."
