PROVISIONAL SPECIFICATION.
An Improved Apparatus for Heating Laundry Irons, Calender
Rollers, and the like..
1, GEORGE EDWARD PAYNE, of '93 Sterndale Road, Hammersmith, in the
County of Middlesex, Laundryman, do hereby declare the nature of this invention
to be as follows:-
"The object of this invention is to enable laundry irons calender rollers and the
like to be heated by means of gas with the minimum consumption of fuel and
without dirtying the face of the iron.
Now according to this invention I provide a burner of approximately the same
shape externally as the inside of the iron or roller. The burner may be a hollow
piece of metal perforated with small holes through which the mixture of gas and
air is passed before ignition. I form lugs on the bottom of the burner to maintain
the said burner at the proper distance from the roller or bottom of the iron.
When used for heating irons I attach to the bottom of the burner a tube sliding
gas tight in a tube or pillar attached to or forming part of a suitable base plate or
stand. The tube attached to the burner is plugged up at the bottom and open at
the top and near the bottom of the tube are ports or holes to admit gas and air to
the burner the gas entering through one port and the air through the other a
diaphram 'being fitted in the tube between the ports to prevent the gas and air
from mixing until clear of the ports.
I provide also similar ports in the outer tube communicating with the gas and
air supply pipes the quantity of each admitted to the heater being regulated by
cocks or valves.
When the iron to be hoated is placed over the burner the weight of the iron
depresses the burner and the ports come opposite to each other and the mixture of
gas and air is ignited by means of a pilot flame issuing from a small burner attached
to a by-pass from the gas tube.
As soon as the iron is removed the burner is raised by means of a spring and the
gas and air cut off owing to the closing of the ports by the movement of the inner
tube leaving only the pilot flame burning the movement of the inner tube being
regulated by suitable stops. As soon as an iron is placed on the heater the gas is
automatically lighted and the iron heated.
By this arrangement there is no waste of fuel as the gas is only burnt while the
irons are being heated. The amount of gas consumed by the pilot jet is but trifling
and if desired the apparatus may be so arranged that the pilot jet is extinguished
when the burner is lighted and vice-versa.
I prefer to supply air under pressure to the burner as by this means I obtain a
greater heat (with the same quantity of gas consumed) than when air at atmospheric
pressure is used.
The irons I prefer to use with my improved heater are made hollow inside the
bottom of the iron being thick and the sides and top comparatively thin I leave an
orifice at the back of the iron to admit the burner and I perforate the iron at or
near the front to allow the products of combustion to escape.

page_text: An Improved. Apparatus for Heating Laundry Irons, Calender
Rollers, and the like.
I GEORGE EDWARD PAYNE of 93 Sterndale Road Hammersmith in the County
of Middlesex Laundryman, do hereby declare the nature of this invention aud in
what manner the same is to 'be performed, to be particularly described and
ascertained in and by the following statement:—
The object of this invention is to enable laundry irons calender rollers, and the
like to be heated by, means, of gas with the minimum, consumption of fuel and
without soiling the face of the iron or roller.
Now according to this invention I provide a burner of approximately. the same
shape externally as the inside of the iron or roller.
The burner may be a hollow piece of metal' perforated with, small holes through
which the mixture of gas and air is passed before ignition. I form lugs on the
bottom of the burner to maintain said burner, at the proper distance from the
roller or bottom of the iron as the case may be. I attach to the bottom of
the burner a tube sliding gas tight in a tube or pillar attached to or forming part
of a suitable base plate or stand.
The tube attached to the burner is plugged up at the bottom and open at the top
and near the bottom of the tube are ports or holes to admit gas and air to the
burner, the gas entering through one port and the air through the other a diaphram
being fitted in the tube between the ports to prevent the gas from mixing until
clear of the ports or until reaching the burner. I provide also similar ports in the
outer tube communicating with the gas and air supply pipes, the quantity of each
admitted to the heater being regulated by suitable cocks or valves.
When the iron, to be heated is placed over the burner the weight of the iron
depresses the burner and the ports come opposite to; each other and the mixture of
gas and air is iguited by means of a pilot flame issuing from a small burner
attached to a bye-pass from the gas tube. As soon as the iron is removed the
burner is raised by means of a spring and the gas and air cut off owing to the
closing of the ports by the movement of the inner tube leaving only the pilot
flame burning the movement of the inner tube being regulated by suitable stops.
As soon as the iron is placed on the heater the gas is automatically lighted by
the pilot flame and the iron heated.
I prefer, to supply,air under pressure to the burner as by this means I obtain
greater leat (with the same quantity of gas consumed) than when air at atmospheric
pressure is used.
The irons I prefer to use with my improved heater are made 'hollow'inside the
bottom of the iron being thick and the sides and top comparatively thin leave an
orifice at the back of the iron to admit the burner and I perforate the iron at or
Dear the front to allow the products of combustion to escape.

And in order that my invention may be fully understood I will proceed to
explain the same with reference to the accompanying sheets of drawings in
which
Fig. 1 represents front view of a heater for laundry irons, constructed according
to this inventiop.
Fig. 2 is section of same.
Fig. 3 is back view of same.
Fig. 4 shews laundry iron being heated.
Fig. 5 shews beater being used for heating an ordinary flat iron.
Fig. 6 shews front view of a modified form of heater.

page_text: · Fig. 9 is plan of burner for theating ironing machine rollers. Fig. 10); is end
view of same.
The same letters denote the same parts in all the figs.
a is base plate or stand preferably of cast iron having therein passages b and c whereof
bis connected to the gas supply pipe and c to the air pipe ore may be simply open
to the atmosphere if air under pressure is not used. The passages band a
communicate with ports de in the pillar which ports correspond with similar
ports g h in the tube i attached to the burner j when the latter'is depressed.
The burner j. is preferably made of cast iron liollow inside and externally of the
same configuration as the inside of the iron with which it is. used.
The front of the burner is pierced with a series of small holes kk. ' are lugs
to maintain the front of the burner at the proper distance from the inside of the
iron. m is a bye-pass from the passage b and terminates in a pilot jet n the flame
from which when the burner is depressed lights the mixture of air and gas issuing
from the burner. is a spring to raise the burner when the iron is removed
therefrom. p is a diaphram which may terminate a short distance above the
ports d and e see Fig. 2. or be continued into the burner see Figs. 5 and 7,
9. are screw valves to regulate the supply of gas to the burner and pilot light
respectively s is a similar valve to regulate the air supply.
The iron most suitable for use with my improved beater is shewn in Fig. 4 and'
is a box iron with an opening at the back to admit the burner.
The bottom of the iron is made thick to retain the heat the sides and 'top' being
comparatively thin.
Holestare formed in the sides of the iron to allow the products of combustion
to escapo.
The sides and bottom of the iron are rounded off as shewn at w to allow the
iron to be used as a polisher. As shewn at Fig. 5, z is a stand or rest which may
be screwed into the bottom of the burner to receive the handle of a common flat
iron thus enabling the heater to be used for domestic as well as laundry. irons.
Tailors and hatters irons may be heated by similar heaters of a size proportional
to the irons to be used.
In the modification shewn by Figs. 6. 7. and 8 I dispense with the sliding tube i
and attach the burner ; to the pillar f. is the gas admission valve which is
depressed by the weight of the iron and raised when the iron is removed from the
burner by the spring o'. The depression of the valvo yopons communication
between the gas nozzle d' and the port g¹ leading to the burner the communication
being out off when the valve is in the position shewn,at Fig. 7. The air is admitted
through the pillar and port e to the back of the perforated diaphram p the supply
of the air is continuous.
m³ is a bye-pass from the nozzle to the pilot light which issues from the
hole k¹.
Burners for heating the rollers for ironing machines, calenders and the like are
formed as shewn by Figs. 9 and 10 being curved to enable the face of the burner
to be maintained at a constant distanco from the interior surface of the roller.
The burners of such machines may be attached to the belt striking gear so that
when the belt is thrown on the loose pulley the burner is drawn out and the move-
ment of the tube attached thereto closes the ports 9. the tube, sliding in an
outer tube provided with ports and regulating valves similar to the arrangement
shewn in Figs. 1. 2 and 3.
Or the burner may be fixed and the belt striking gear connected to the outer
tube which is moved over the tube i when the belt is shifted.
Or the belt striking gear may operate cocks or valves controlling the supply of
gas and air thus dispensing with the telescopic tubes.
With this apparatus there is no waste of fuel as the gas is only burnt when the
irons or cylinders are being heated, and if desired the pilot flame may be auto-
matically extinguished when the burner is lighted and vice versa.
