Improvements in Gas Heating, Cooking, and Vaporising Apparatus.
1, HERBERT PEROY MILLER of 15 Craven Terrace Hyde Park in the County of
Middlesex Engineer do hereby declare the nature of this invention to be as
follows:-
This Invention relates to further improvements in my improved gas heating
apparatus for which I have obtained the grant of Letters Patent No. 9354 of 1885,
and has for its object to render such apparatus more effective and convenient.
My first improvement consists in making such apparatus portable by fitting it
with a suitable frame or stand so as to readily change its position and move it to
any part of the room.
My second improvement consists in fitting such stand with a cup, dish or other
suitable receptacle for holding water which when placed therein gradually evaporates
and so prevents the surrounding atmosphere from becoming too dry through the action
of the beating apparatus―This improvement will be found particularly serviceable
for invalids.
A third improvement consists in fitting such apparatus with a flexible tube so as to
allow of its being readily connected to the gas supply at any convenient point and in
fitting such tube with a suitable union consisting of a nozzle fitted with a rubber
washer which is held in position by a metal plate that is fitted to the nozzle.
A fourth improvement consists in reversing the position of the tube or column of
fire clay terra cotta or other suitable material described in the Specification of my
said previous patent so that the collar or enlargement thereon is at the top and in
forming flutings or corrugations on such collar or enlargement so as to increase
the radiation of the heat therefrom while a dome is fitted thereto as described in
the Specification of the above mentioned Letters Patent. By this improved arrange-
ment the gas flame is thrown vertically on to the column while the waste products
of combustion ascend into the chamber formed by the before mentioned dome
and are there consumed instead of vitiating the surrounding atmosphere.
A fifth improvement consists in fitting the central rod with a movable stand
which serves to carry a small kettle or other suitable vessel so that by removing
the dome and substituting the movable stand therefor and placing the kettle or
other vessel on such stand hot water or any light food may be obtained or prepared
in a few minutes. A sixth improvement consists in fitting the bottom of the
apparatus with a supply pipe the upper end of which is provided. with a burner
and tap so that when heating the water or preparing the food an independent light
can be obtained by turning on the tap and igniting the burner. This will be found
extremely convenient in bedrooms and other apartments which are only fitted with
a single gas bracket as when the cap of the flexible tube is placed on such
bracket in order to obtain the necessary gas supply for the apparatus by simply
turning on the tap and igniting the burner as already described a sufficient light is
at once obtained and all necessity for a candle or lamp is obviated.
By removing the stand and kettle or other vessel and replacing the dome the
apparatus can at once again be employed simply as a heating apparatus or if required
the cup or other receptacle for water can remain attached thereto so as to ensure a
moist atmosphere. One great advantage of my improved apparatus is that no injurious
fumes are generated thereby.

Improvements in Gas Heating, Cooking, and Vaporising Apparatus.
I, HERBERT PERCY MILLER of 15 Craven Terrace, Hyde Park in the County
of Middlesex, 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 :-
The object of my invention is to supply a simple and effective apparatus whereby a
room may be readily warmed and any light food quickly cooked, while a healthy
degree of moisture is maintained in the surrounding atmosphere. This I effect by
the apparatus illustrated in the accompanying drawings. Such apparatus may either
be suspended from an ordinary gas burner, or placed on a table or elsewhere. Fig. 1,
shews the apparatus complete, and Figures 2, 3, and 4, shew detail views of certain
parts thereof as presently mentioned. Similar letters of reference indicate corre-
sponding parts throughout the several figures..
Such apparatus consists of an atmospheric burner a, screwed on to a threaded
collar b, furnished with a nipple 61, fixed in a junction piece c, and provided with a
tail piece d, terminating in a short screw spindle e. A supply pipe, fitted with a
tap g, jet g and screen plate h is screwed into the junction piece c. The top of such
supply pipe is screw threaded and furnished with a nozzle i which fits over the nipple
of the gas burner and serves to connect the apparatus therewith.
When the apparatus
is stood on a table or elsewhere the nozzle is provided with a metal tubular extension j
to allow of its being connected to a length of elastic tubing the other end whereof
is connected to the supply pipe in any convenient manner. The atmospheric
burner a is furnished with a spindle over which a socket rod having a base
plate fits telescopically as shewn in detail at figure 2. This rod carries a terra cotta
tube that fits loosely thereon. Such tube is taper towards the top while at the
bottom it expands into a fluted bulb and terminates at its base in a collar that takes
it seating on the base plate k². The terra cotta tube is held in position by a metal
cap not shown in the drawings which is furnished on its underside with a rim that fits
into the top of the terra cotta tube. This cap forms a seating for a terra cotta dome n
which takes its seating on the top of the rod & and is secured thereon by a screw nuto.
The atmospheric burner and terra cotta tube are surrounded by a wire cage p which
fits over the threaded collar b and is held in position by the atmospheric burner when
the latter is screwed down. This cage is shewn broken away in the drawing in order
that the other parts of the apparatus may be clearly seen. It is furnished with a
rim p¹, so that on unscrewing the nut o and taking off the dome n a small kettle or
saucepan can be placed on such rim and the contents heated; while by turning the
tap g and igniting the jet g' sufficient light is obtained to dispense with a candle or
lamp. The screen plate / prevents the ascending heat from injuring the gas fitting
and nozzle. is a cup shaped vaporiser affixed to the screw spindle e. This
vaporiser is filled with water, which, as it becomes warm, is given off in the form
of vapour in the surrounding atmosphere; thus preserving a healthy degree of
moisture therein. The vaporiser is provided at the bottom with a screw pins, to
which a tripod g is attached which forms a stand for the apparatus. If desired the
vaporiser may be dispensed with and the tripod screwed on to the spindle e. Fig. 3
shews a detail view of the nozzle-i is the top-ian india rubber washer which
prevents any leakage of gas- a metal plate to hold washer in position which is
secured to the nozzle by screws 13. The washer and plate each have a central aperture
therein to allow of the pipe or union being fitted to the nozzle.
One great advantage of my apparatus is that the surrounding atmosphere is
quickly heated without being charged with any poisonous or offensive fumes. It is
therefore particularly adapted for use for invalids and children, and persons of
delicate susceptibility. This is owing to the fact that the gas flame is thrown
vertically on to the terra-cotta tube while the waste products of combustion ascend into
the terra cotta dome, where they are consumed, instead of escaping and vitiating the

page_text: surrounding atmosphere. My invention combines the essential advantages of safety,
simplicity, utility, portability, cleanliness, and economy. It can be put into immediate
operation by attaching the nozzle or union to any gas burner, and left with perfect.
safety for several hours together as it requires no further attention when used for
heating purposes only.
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
An improved portable combination gas heating cooking and vaporising apparatus
consisting of atmospheric burner a, spindle k, threaded collar b, nipple b¹, junction
piece c, tail piece d, screw spindle e, supply pipe f, tap 9, jet g', screen plate h, nozzle i,
socket rod, terra cotta tube i, dome n, nut o, cage p, with rim pl tripod base and
vaporiser with screw pin s all respectively constructed combined, arranged and
fitted substantially in the manner and for the purposes hereinbefore described
and shown.
