PROVISIONAL SPECIFICATION.
Improvements in and relating to Heating Appliances for Laundry
and other Irons, applicable also for other purposes.
We, JOHN MANNING of 26 and 28, Old Street, St. Lukes, London, E.C.
Manufacturer, and JAMES ROBERT SLADE HAYES, of 16 Hazelville Road,
Hornsey Rise, London, N., Engineer do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in, and connected with heating appliances
for laundry and other irons, which improvements are also applicable for other
purposes such as converging a mixture of gas and air to the combustion chamber
or chambers of various contrivances such as japanning ovens and stoves, steam
boilers, gold blocking presses, coppers, and heat radiators generally, and. of
automatically withdrawing all noxious fumes from the aforesaid combustion
chamber or chambers, and thereby preventing the unpleasantness, and injurious
effects now and heretofore consequent upon the escape of such fumes into the work
room or operating apartment..
In carrying out our invention we have a three-main pipe traversing the length
of the work bench. One main is for the supply of gas, the second is for
atmospheric air under pressure, and the third acts as exhaust for noxious fumes.
Attached at suitable intervals to the aforesaid three-main pipe we have a three-way
regulator or valve acting as a converger of the gas and air to the combustion
chamber of the iron or other article, and as an exhaust of the noxious fumes from
said combustion chamber. The three-way regulator or valve is formed with two
nozzles to which are attached flexible tubes in connection with the iron or other
heat radiator. The gas and air passages of the regulator lead into one nozzle and
are controlled by a suitably arranged valve; the other nozzle is the exhaust for
the withdrawal of noxious fumes from the combustion chamber and is always open
to the exhaust main of the three-main pipe aforesaid which may if preferred be
fitted or arranged with a fan for the purpose of facilitating the withdrawal or exhaust
of said fumes. To adapt the iron or other heat radiator for proper connection
with the flexible tubes in connection with the regulator before mentioned we, form
the iron or other radiator preferably in two horizontal compartments into the upper
one of which, by a suitable nozzle to which the gas and air tube is connected, the
mixture of gas and air is conducted in desired proportions, which proportions may
be regulated as required by the valve provided as aforesaid. The division between
the two compartments is perforated to allow the mixture of gas and air to percolate
into the bottom compartment or combustion chamber where it is ignited in any
suitable manner through an ignition box attached thereto, and from whence the
noxious fumes and products of combustion are withdrawn or pass into the exhaust
main aforesaid through a suitable nozzle connected to the ignition box. To this.
nozzle the flexible tube leading to the exhaust main is connected, and to prevent
any escape of the lighted gas through the nozzle when the iron is tilted or raised
from the horizontal position we place within said nozzle a valve which automatically
closes as said iron is raised or tilted. We further arrange at nozzle end of.
combustion chamber and in such manner as to control the entrance to the exhaust
ozzle, a suitable baffle plate, and to aid the process of ignition and to effectually

page_text: prevent any outrush of the lighted gas from the combustion chamber we place at
the otherwise open end of the combustion chamber a gauge plate suitably arranged
and shaped to admit of the entrance of a certain amount of atmospheric air
necessary for combustion and yet prevent any outrush when as in the case of
laundry and other irons said irons are moved to and fro.
The ignition box aforesaid is formed with an opening therein which may be fitted
with mica or other suitable heat resisting material sufficiently transparent to
permit the gas sparks within the combustion chamber to be observed so that the
gas and air valve aforesaid may be operated as required.

Improvements in and relating to Heating Appliances for Laundry
and other Irons, applicable also for other purposes.
We JOHN MANNING, of 26 and 28 Old Street, St. Lukes, London, E.C.
Manufacturer and JAMES ROBERT SLADE HAYES, of 16 Hazelville Roal,
Hornsey Rise, London, N., Engineer, 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, that is to say :-
This invention relates to improvements in, and connected with, the heating
appliances of laundry and other irons, which improvements are also applicable for
other purposes such as converging a mixture of gas and air to the combustion
chamber of various contrivances such as japanning ovens, steam boilers, gold
blocking presses, coppers, and heat radiators generally, and of automatically
withdrawing all noxious fumes from the aforesaid combustion chamber or chambers,
and thereby preventing the unpleasantness and injurious effects heretofore
consequent upon the escape of such fumes into the work room. or operating
apartment.
In carrying out our invention we have a three main pipe traversing the length
of the work bench. One main is for the supply of gas, the second is for
atmospheric air under pressure, and the third acts as exhaust for noxious fumes.
Attached at suitable intervals to the aforesaid three main pipe we have a three
way regulator or valve acting as a converger of the air and gas to the combustion
chamber of the iron, stove, or other heat radiator, and as an exhaust of the noxious
fumes from said combustion chamber. The three way regulator or valve is formed
with two nozzles to which are attached flexible tubes in connection with the iron
or other heat radiator. The gas and air passages of the regulator lead into one
nozzle and are controlled by a suitably arranged valve; the other nozzle is the
exhaust for the withdrawal of noxious fumes from the combustion chamber and is
always open to the exhaust main of the three main pipe aforesaid which may
preferred be fitted or arranged with a fan for the purpose of facilitating the
withdrawal or exhaust of said funner. To adapt the iron, stove, or other heat
radiator for proper connection with the flexible tubes in connection with the
regulator before mentioned we form the iron, stove, or other radiator, preferably
in two horizontal compartments into one of which by a suitable nozzle to which the
gas and air tube is connected the mixture of gas and air is conducted. The division
between the two compartments is perforated to allow the mixture of air and gas to
percolate from one into the other where it is ignited in any suitable manner through
if

page_text: an ignition box attached thereto, and from whence the noxious fumes and products
of combustion are withdrawn or pass into the exhaust main aforesaid through a
suitable nozzle connected to the ignition box. To this nozzle the flexible tube
leading to the exhaust main is connected, and to prevent any escape of the lighted
gus through the nozzle when the iron is tilted or raised from the horizontal position
we place within said nozzle a valve which automatically closes as said iron is so
raised or tilted. We further arrange in such manner as to control the entrance of
the exhaust nozzle a suitable baffle plate, and to aid the process of ignition and to
effectually prevent any outrush of the lighted gas from the combustion chamber
we place at the other wise open end of the combustion chamber a gauge plate or
damper capable of manipulation to permit of its being opened for ignition and of
then being closed so as to prevent any outrush of flame when as in the case of
laundry and other irons said irons are moved to and fro. The ignition box
aforesaid is formed with an opening therein which may be fitted with mica or other
suitable heat resisting material sufficiently transparent to permit the gas sparks
within the combustion chamber to be observed so that the air and gas valve
aforesaid may be operated as required.

applied.
Similar letters of reference.indicate like parts throughout all the figures.
a Figs. 1. 10. and 14 is the three main pipe. One main a' being for the supply
of gas, the second a' for atmospheric air under pressure, and the third a acting as
exhaust for noxious fumes. When required, à fan (not shewn in the drawings)
may be used in connection with the exhaust to assist in the withdrawal of the
fumes and products of combustion. b Figs. 1. 9. 10. and 11 represents one of the
three way regulators or valves above referred to as acting as convergers of
the gas and air to the combustion chamber and as an exhaust of the noxious fumes
attached at suitable intervals to the aforesaid three main pipe a. 61 Figs. 2 and 3
represents the work bench. The regulator b is formed with two nozzles c and d to
which are attached flexible tubes in connection with similar nozzles e and upon
the iron, stove, or other heat radiator. The gas and air passages of the regulator
marked respectively 9 and gl upon the drawings (see Figs. 10 & 11) lead into the
bozzle marked e al are controlled by the valve à Figs. 1, 104, 11. 12. and 13.
These passages g and g₁ are not bored directly through the regulator but as will
с

page_text: more particularly be seen upon reference to Figs. 10 and 10% are each formed with
right angled branches g³ 9 which are only in communication one with the other
upon the valve (formed with grooves or channels upon its surface) being
turned by means of handle h attached to spindle so that the channels h¹ and
cover the openings of the branches g g respectively. Hence the inflow of gas
and air may be regulated at will. The nozzle d is the exhaust for the withdrawal
of noxious fumes from the combustion chamber (a flexible tube-not shewn-
connecting same with the exhaust nozzle f of combustion chamber) and is always
open to the exhaust main a³ of the three main pipe a.
i and Fig. 3 are respectively the upper and lower compartments of the
combustion chamber of the iron, stove, or other heat radiator into the upper one
of which i by the nozzle e to which the flexible tube leading from the gas and air
nozzle c of the converger is connected, the mixture of gas and air is conducted.
The division between the two compartments and k is perforated as at sce
also Fig. 4 to allow the mixture of gas and air to percolate into the bottom
compartment where it is ignited in any suitable manner through the ignition box l
attached thereto, and from whence the noxious fumes and products of combustion
are withdrawn and pass into the exhaust main as aforesaid through apertures m
and nozzle f connected to the ignition box l. To prevent any escape of the lighted
gas through nozzle when the iron is tilted we place within said nozzle the valve m
Figs. 5 and 6. This valve is shewn in its normal position, as when the iron is
horizontal, allowing free passage from combustion chamber through aperture
and space m¹ into the exhaust nozzle f, but upon the iron being tilted the valve m
will slide forward and close the space m¹ and cover the aperture and thus
prevent any liability of hack firing. n is a baffle plate tending to guide the fumes
to exhaust outlet and o is a gauge plate or damper preferably hinged, aud capable
of being operated by a handle o¹ (Fig. 8). o are openings in the bottom of the
ignition box covered by the plate o. This latter is turned so as to open the
apertures o² when it is desired to light the gas in combustion chamber, and when
released it immediately closes the openings o and thereby prevents any outrush of
flame when, as in the case of laundry and other irons, said irons are moved to and
fro. The ignition box is formed with the opening p therein which is fitted with
mica or other suitable heat resisting material sufficiently transparent as aforesaid
to permit the gas sparks within the combustion chamber to be observed so that the
converger valve / may be operated as required.
q Figs. 14 and 15 is a safety valve placed upon the end of air main a² of the three
main pipe a. This valve may conveniently be formed of a flat metal disc having
spindle q which is passed through a central aperture formed in the closed end of
air main a². rrare perforations formed in the aforesaid closed end of the air main
and which are covered by the valve q. Should any rush or explosion occur the
valve q
would be raised sufficiently to allow free passage through the apertures r
and thus all danger therefrom be obviated.
To adapt old laundry irons for use with this invention we make use of a specially
constructed covers see Figs. 16, 17, & 18. This is formed with a channel or
passages around same to which the exhaust nozzle f is connected or attached and
into which by a passage t conveniently formed at front end of the iron the fumes
and products of combustion from chamber k pass. In lieu of the ignition box!
previously described we, at the otherwise open end of combustion chamber k
see Fig. 18, hinge a flap or plate u suitably weighted to automatically keep closed,
which will serve to prevent any outrush of flame and which may easily be raised
to allow of ignition.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed we declare that what we
claim is :-
