Improvements in and relating to Oil Lamp or Gas Burner Heating
and Cooking Appliances, the Oil Lamp of which is applicable
for Lighting Purposes.
I, GEORGE ROBERTSON of 46 Dale Street, Kingston Glasgow North Britain
Sheet Metal Worker do hereby declare the nature of this invention to be as
follows:-
It relates to appliances which are designed for use with or heated by means of
gas or oil flames and has for its objects to adapt them for warming, drying
cooking, boiling, water-circulating, steam-generating, sterilizing, lighting and other
purposes.
One modification of this invention comprises an oil lamp enclosed within a glass
globe surmounted with one or tnore metal or metal and earthenware tubes for
confining and conveying the heat proceeding from the lighted lamp until it has
been utilized for drying, heating, cooking or other purposes. This glass globe has
a metal chimney fitted upon it in preference to being made with a fragile glass
continuation, as the latter is very liable to be broken with alternations of heat and
cold. Above this lamp a short vertical tube is fixed; it is open at the top and
bottom but has a moveable cover on the top and a lateral or sloping tube consisting
of one or more sections, connected therewith and opening out of it. These tubes
are each, or either of them, made of metal or baked clay. The cover is made
removeable from the tube immediately above the lamp in order that cooking
utensils may be placed thereon. The first length or section of the lateral tube is
fitted or formed within an enveloping chamber, boiler or tubular jacket adapted
for use as a drying chamber, cooking oven, warming, boiling, water-circulating or
steam-generating appliance.
These appliances are designed for being fixed immoveably upon the floor or wall
of an apartment or structure, at any required elevation or, moveably upon a board,
plate or structure. When they are attached to a wall or other structure, at a
suitable height, the lamp gives light to the apartment during the time that they
are in use for the other purposes specified, or any of them. This oil lamp is
separable from the above named superstructure and is adapted and designed for use
in conjunction therewith or when separated from it.
Another modification of this invention comprises all the foregoing devices with
the exception of the oil lamp; a gas burner being substituted for the oil burner or
wick; this lamp is removeable from the superstructure and adapted for use apart
therefrom. In this modification the gas is made to pass through a Bunsen burner
and the jacketted boiler or section of lateral tube is made preferably of copper,
furnished with inlet and outlet orifices and tinned inside when the interior is
designed for use as a boiling vessel for warming milk water or other articles of
food. If these appliances are required for hot water circulation, the copper
jacketted tube or boiler is fitted with pipes connecting it with a supply and
intermediate circulating cistern and pipes for drawing off hot water.
required for producing steam for use in a vapour bath, model engine or other
appliance this copper jacketted tube or boiler is furnished with devices for drawing
off the steam or water and for filling the vessel.
When

page_text: The boiler jacketted tube section is sometimes made with a double jacket or
boiler one formed outside of or upon the other with devices for filling and emptying
each, so that a boiling heat may be obtained in the inner chamber and a milder
heat in the outer one.
In another modification of this invention the jacketted tube is made as an oven
for insertion of surgical and other articles for sterilizing, drying, heating and other
purposes.
In any of the aforesaid modifications the hot current which proceeds from the
lamp flame after passing through the lateral tube or tubes is either emitted into
the apartment or carried off from it to the outside the substance of the tube
whether it is made of metal or baked clay becomes heated by the hot current
within it and gives off the heat to the atmosphere surrounding it: if the tube is a
long one almost the whole of the heat is absorbed by it and given off by radiation
from its outer surface.
The appliances herein described are designed also for drying clothes in a nursery
or laundry the clothes being suspended either upon a frame above the lateral tube
or in the open apartment.
The metal chimney combined with the glass globe of the lamp as herein
described in lien of a globe and chimney made all of glass in one piece has been
found of greater service than the glass chimney, as the globe is often rendered
useless by the breaking of the glass chimney, therefore by making my lamp
chimney of metal separable from and capable of union with the glass globe each
such globe is adapted for rendering longer service than any of those made in the
old way.
The glass globe being separable from the chimney and the chimney from the
globe each part is adapted for being cleaned more rapidly safely and perfectly than
lamp globes and chimneys made as formerly.

Improvements in and relating to Oil Lamp or Gas Burner Heating
and Cooking Appliances, the Oil Lamp of which is applicable
for Lighting Purposes.
I, GEORGE ROBERTSON of 46 Dale Street, Kingston Glasgow North Britain
Sheet Metal Worker, 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:-
It relates to appliances which are designed for use with or heated by means of
gas or oil flames and has for its objects to adapt them for warming, drying,
cooking, boiling, water-circulating, steain-generating, sterilizing, lighting and other
purposes.
The invention will be better understood if reference is made to the accom-
panying drawings in which:
Figure 1 is a view in elevation of au oil lamp with tubular superstructure and
extensions made in accordance with this invention.
Figure 2 is a view in elevation of a lamp similar to that shewa in Fig. 1:
separate from the heating apparatus.
Figures 3 and 4 are views shewing details of the said lamp.

page_text: Figure 5 is a view in elevation of a tubular superstructure and continuations
with gas lamp made in accordance with this invention.
Figures 6 and 7 are views in elevation, similar to Fig. 5, each having a gas
burner, tubular superstructure and extensions made in accordance with this
invention.
Figure 8 is a fragmentary view in elevation and section of a tubular super-
structure and continuations made in accordance with this invention.
Similar letters of reference and numerals throughout the illustrations indicate
corresponding parts.
One modification of this invention is shewn in Figure 1 and comprises an oil
lamp A the burner of which, a' is enclosed within a glass globe a surmounted with
one or more metal, (or metal and earthenware) tubes a³, B, 61, 62, 63, for confining
and conveying the heat proceeding from the lighted lamp until it has been utilized
for drying, heating, cooking or other purposes.
This glass globe a', Figs. 1, 2 and 4 has a metal chimuey as fitted upon it in
preference to being made with a fragile glass continuation, or chimney, as the
latter kind is very liable to be broken with alternations of heat and cold. A short
neck.a is, formed upon the glass globe, see Fig. 4, and the corresponding part of
the chimney a Fig. 3 is made with slits a corrugations or other devices for
enabling it to be fitted tightly upon the neck or flange a.
Above this lamp a short vertical tube B is fixed; it is open at the top and
bottom but has a moveable cover bon the top and a lateral (or sloping) tube 6³
consisting of one or more sections, connected therewith and opening out of it at b
or 62 or at both of the said outlets. These tubes B, 63 are each or either of them
made of metal or baked clay. The cover , immediately above the lamp, is made
removeable from the tube B in order that cooking utensils may be placed over the
orifice left by the removal of the said cover. The cover b' is removeable as a lid
or by revolving upon a pin or pivot & or the said pivot may be a split pin as
shewn in the drawings easily taken out. The first or any subsequent length or
section of the lateral tube 63 is fitted or formed as occasion requires within an
enveloping chamber C, boiler c', c2 or tubular jacket c, c, variously adapted for
use as a drying chamber, cooking oven, warming, boiling, water-circulating or
steam-generating appliance.
These appliances are designed for being fixed immoveably upon the floor or wall
of an apartment or structure at any required height or moveably upon a board
plate or portable structure. The brackets D, d', d2, Figs. 1, 2 and 6 are adapted
for supporting the appliances upon a wall or upright boarding and the pillar E or
pedestal e Figs. 5 and 7 upon a floor plate or board. When they are attached to
a wall or other structure, at a suitable height, the lamp gives light to the apartment
during the time that they are all either or any of them in use for the other
purposes specified. This oil lamp A a², a³ is separable from the above named
superstructure B, 6, 2, and is adapted and designed for use in conjunction there-
with or when separated from it as shewn in Fig. 2.
Another modification of this invention comprises, by turns, all the foregoing
devices except the oil lamp: a gas burner being substituted for the oil burner or
wick: this gas lamp is removeable from the superstructure B, 61, 62, by unscrewing
or otherwise and is adapted for use apart therefrom: it is capable of attachment
thereto but is not an integral part of it. In this (gas lamp) modification the gas
is made to pass through a Bunsen burner F or f¹ Figs. 5, 6 or 7 and the jacketted
section or boiler C, c, c, of lateral tubing is made preferably of copper, furnished
with inlet and outlet orifices c c c, c Figures 7 and 8 and is tinned inside when
the interior is designed for use as a boiling vessel for warming milk water or other
article of food:
If these appliances are required for hot water circulation the copper jacketted
tube or boiler c Fig. 5 is fitted with pipes G, g', g², connecting it with a supply
and intermediate circulating cistern H, h, and one or more pipes g³, for drawing
off hot water. 9 is an expansion pipe.

page_text: When this copper jacketted tube or boiler Fig. 7 is required for producing
steam for use in a vapour bath, model engine or other apparatus it is furnished
with devices c, c', for drawing off the water or steam and a cup c³ for filling the
vessel.
The boiler jacketted tube section is sometimes made with a double jacket or
boiler, one of them c being formed outside of or upon the other c8 with devices c³:
to see Fig. 8 for filling and emptying each, so that a boiling heat may be
obtained in the inner chamber and a milder heat in the outer one when combined
with the devices B, b', or b², F or other burners and in operation.
In another modification of this invention the jacketted tube is made as an
oven, C, co Fig. 1, for insertion of surgical and other articles for sterilizing,
drying, heating and other purposes. The metal chimney extension of the glass
globe a is indicated by dotted lines in Fig. 1, and the vessel C is shewn as an
oven with the lid co turned back upon the hinge c".
The globe a², Fig. 4, with or without metal chimney a³ Fig. 3, is intended to be
used with a gas burner f¹ such as that shewn in Fig. 6 or other suitable kind
when required as these improved devices are not restricted to an oil lamp.
The Bunsen gas burner F, f', for heating these appliances is intended to be
used with or without a glass shade or globe: it is shewn inside a glass bowl f2 in
Fig. 6 and without any cover in Figs. 5 and 7.
The steam pipe c, Fig. 7 can be easily removed, by unscrewing or otherwise,
and the cup shewn by dotted lines at c³, inserted in the part c¹³ containing the tap
for filling the boiler c.
In Figs. 1, 5 and 7 the hot air tube 63 is indicated by dotted lines as passing
through the parts C, c¹, c².
In Fig. 5 the tubular device B, b1, b2, b is shewn with an extending tube
connected to it both at band 62, but in Figs. 1, 6, 7 and 8 a cap or cover b
closes one opening (6 or 62) and compels the hot current to pass through the
pipe 63.
These improved appliances are designed for construction and use in single or
multiple arrangements in single arrangements such as those indicated by
Figures 1, 5, 6, 7 and 8; or with two three or more of the devices C, c', c2, c8, c³,
affixed upon a continuous range of the tube 63. One modification of this kind
might, for example, comprise the devices B, 61, 62, 63, 4, with lamp F as shewn
in Fig. 5 and having the boiler c¹ on the right hand of B and one such as c² Fig. 7
on the left of it; and on the right and left of these parts (cl c²) two ovens
such as C Fig. 1 can be fitted, or two boilers such as c8, c, Fig. 8 or an oven on
the one side and a boiler on the other.
In any of the aforesaid modifications the hot current which proceeds from the
lamp flame, after passing through the lateral tube 63 (or tubes) is either emitted
into the apartment or carried off from it to the outside: the substance of the
tube 3, whether it is made of metal or baked clay, becomes heated by the hot
current within it and gives off the heat to the atmosphere surrounding it: if the
tube is a long one almost the whole of the heat is absorbed by it and given off
by radiation (or filtration) from its outer surface.
The upper and lower parts of the tubular device B are of a conical form
internally, for the purpose of agitating and breaking up the hot current.
I find that by somewhat extending the tube 3 the material of which it is
composed absorbs and filters the hot current so that its noxious character is
completely annulled and changed by its action upon and absorption into the
substance of the tube and is not given off into the atmosphere of the apartment in
a form inimical to vegetable or animal life. This being so the tube 63 does no
require to be fixed into a chimney but its ends may be open to the apartinent.
The appliances herein described are designed for drying clothes in a nurser
or laundry as well as the other purposes mentioned herein, the said clothe
being suspended either upon a frame above the lateral tube 63 or. in the oper
apartment.

page_text: The metal chimney a3 which is combined with the glass globe a², of the lamp as.
herein described in lieu of a globe and chimney made all of glass in one piece has
been found of greater service than the glass chimney; as the globe a is often
rendered useless by the breaking of the glass chimney: therefore by making my
lamp chimney of metal and separable from and capable of union with the glass globe-
each such globe is adapted for rendering longer service than any of those made.
in the old way.
The glass globe a Fig. 4 being separable from the chimney a Fig. 3 and the
chimney from the globe each part is adapted for being cleaned more rapidly,.
safely and perfectly than lamp globes and chimneys made as formerly.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
First. The tubular device B, 61, 62, 64, 6, double cone shaped internally all
substantially as herein described and drawn or any mere modification thereof for
the purposes specified.
Second. The combination of the tubular devices B, 63, all substantially as.
