PROVISIONAL SPECIFICATION.
Improved Portable Apparatus for Generating Oil, Gas, or Vapour
for Heating, Drain Testing, and other Purposes.
I, GEORGE ROSE Engineer Gowenlee Bishopbriggs do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in and connected with apparatus for
generating heat from oil vapour or gas with or without an admixture of air same
as the Bunsen principle or from a separate air supply either from air compresser or
blower & has for its object to simplify the construction or arrangement of parts of
such heating apparatus. Heating apparatus as heretofore constructed have always
had a cover, casing or air mixing chamber surrounding or attached to the said gas
or vapour generators. Under this invention all necessity of all such like can be
dispensed with. Portable & self-contained apparatus under this invention can be
made much cheaper than hitherto & can also be made much more portable. The
apparatus can be mounted on wheels or be provided with carrying handles. Under
I have
one form of my invention 1 make an apparatus in the following manner.
a strongly made tank of any suitable material on the top of this tank is fitted a
small hand air pump pressure-gauge & filling screw, there is also fitted on the top
a valve or cock, on the underside of this valve or cock is fitted a metal tube for
the purpose of conveying the oil to the generator this pipe goes inside the tauk,
when the valve or cock is fitted on to the body of the tank near the bottom the
pipe alluded to may be dispensed with. The gas generator is made of an annular
form the flame passage being circular the body which is the outside shell may be
round square or any suitable shape & would have suitable cleaning arrangements
round same.
The inside of the flame passage is made larger than the inlet &
outlet which is both ends of the gas generator. By having this enlargement I get
the air & vapour to mix better & so produce a greater heat than it would otherwise
do if the flame passage was parallel. The oil is allowed to come in at the underside
of the gas generator the gas is allowed to pass along a tube on the top which is
screwed into gas generator. On one end of this tube is fitted a piece with hexagon
or square facets, the top side is bored & screwed to fit the pipe aforementioned.
On one of the sides of hexagon piece a hole is bored & screwed to fit a small
nipple, this nipple has a hole through is for the purpose of allowing this gas to
escape through it. The nipple being small it is easily removed & thus obviates
Whenever a flat flame
the necessity of taking the apparatus asunder to do this.
is wanted 1 fit an hinged deflecting plate on to the outside of outlet end of the
gas generator. I may also use a cap or fit a small plate in the inside of the gas
generator at the outlet end. Either of the above will serve the same purpose.
With this apparatus I prefer to use two or more burners placed alongside side
of each other, or a number of them may be grouped together each having a
separate oil valve or cock, or a number may be attached by having a solid pin or
screw screwed into the body of the aforementioned & thus make them fast together.
To keep them from shifting an oval shaped casing would be fitted tight on to the
gas generator thus fastened together so as to allow a proper thickness of metal for
the fittings to be screwed into. I weld on a thickening piece on to the body of
the generator. Under a modification I make a burner having a circular body about
one inch deep, this burner is to be used for boiling purposes the oil comes in at

page_text: the bottom & the gas generated therein is led by a separate pipe connection in a
downward direction, the gas impinges on the bottom or top & so causes the flame
to spread out. When the apparatus is used for steam launches I may use one or
more burners placed at suitable places in the fire box & by allowing the gases to
mix with coke or any loose carbonaceous substance a powerful heat is thus generated
& so make steam quickly. The gases made are not luminous. I also propose to
use this apparatus as a plumbers forge to melt lead or solder, or for smoking
drains in this case the flame would be allowed to go into a box where combustible
matter is, the smoke rising of same would be forced into the drain through a
small funnel by the force of the flame. A small oil tank is fitted to generator or
sits alongside of same the oil makes the smoke to test the drains or soil pipes.

Improved Portable Apparatus for Generating Oil, Gas, or Vapour
for Heating, Drain Testing, and other Purposes.
1, GEORGE ROSE of Gowanlee, Bishopbriggs, near Glasgow, 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:-
This invention, relates to improvements in and connected with apparatus for
generating heat from oil vapour and gas with or without the admixture therewith
of air from an air compressor or blower and it has for its object to simplify and
improve the construction of such apparatus.
The apparatus can be adapted and arranged for use as a drain tester and as a
plumbers' forge.
The apparatus is portable and self contained.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon,
Fig. 1 is a perspective view of the apparatus adapted and arranged as a drain
tester.
Fig. 2 is a perspective view of the apparatus adapted and arranged as a plumbers'
forge.
Fig. 3 is a longitudinal vertical section of the burner and vapour generating
chamber.
Fig. 4 is an enlarged sectional plan of the burner, Fig. 3.
Fig. 5 is a side elevation of a burner and vapour generating chamber adapted
for boiling purposes.
Fig. 6 is an enlarged sectional view of part of a modified arrangement of smoke
testing device for drains.
Fig. 7 is a perspective view of a slight modification of the receptacle Fig. 2.
Referring to the drawings:-
The apparatus consists of a strongly made oil tank a of any suitable material
which is provided with an air pump 6 for raising an air pressure in the tank so as
to force the oil to the burner, a filling screw or plug c, and, if necessary, a pressure
gauge. Fitted in the tank is a stand tube d, provided with a valve e, which
conveys oil from the tank to the vapour generating chamber f. This chamber, as
shown at Fig. 3, is of annular form with a flame passage through it, made larger at
the centre than at each end, for the purpose of obtaining a better admixture of the
air and gas and thereby producing a greater heat than if the passage was made of
the same diameter throughout. The oil enters the chamber f from the tube d, at
the underside at f, and the vapour escapes by the pipe g, to the burner h. This

page_text: burner as shown more particularly at Fig. 4, consists of a hexagon shaped hollow
piece h¹ (so shaped for convenience in screwing by means of a spanner or key)
made with a hollow projection h² and which is screwed on to the pipe g. A nipple i
is screwed into the inside of the projection of the burner whilst a casing j is
screwed on to its outside.
When it is desired to produce a spread or flat flame a deflecting plate k, see dotted
lines Fig. 3, may be hinge jointed to the end of the chamber f.
x Figs. 1 and 2 is the usual saucer for holding oil saturated waste used for
starting the generator.
When the apparatus is used for smoke testing purposes a receptacle m is fitted
on top of a pillar n secured to the oil tank a. In this receptacle an oil vessel o is
placed from which oil runs by the pipe p to the interior of a removable elbow
pipe q leading to the drain. The oil, which is preferably thick, strong smelling
oil, from the vessel o trickles into the pipe 9 and is converted by the heat, into a
strong smelling heavy vapour which is driven by the flame into the pipe 9 and
drain.
If desired instead of using the arrangement with oil can o, etc., as shown in
Fig. 1, the arrangement shown in Fig. 6 may be used. In this arrangement a
perforated cylinder r filled with oil saturated waste or equivalent smoke producing
material is placed in the elbow pipe q'into which the flame plays. The flame
playing on and burning the waste in the cylinder causes a dense smoke to issue
therefrom which is driven into the drain. The waste charged cylinders can be
replaced by fresh ones when necessary.
In the plumbers' forge arrangement shown at Fig. 2 the flame is caused to play
into the receptacle m and heat up a pot s containing lead or the like. A hole t
(Fig. 7) may be made in the side of the receptacle for passing in a soldering bolt
to be heated. If desired as shown in Fig. 7 a cover plate u may be fitted on the
receptacle in this case the pot s would sit in a hole in the cover.
In some cases for boiling purposes an arrangement as shown at Fig. 5 may be
used. This device consists of a shallow cylinder v, forming the vapour generating
chamber, upon which the flame from the overhead burner v' beats. is the oil
supply pipe and cleaning plugs or screws. is the vapour pipe with the burner
nipple at its end.
If desired an air jet from an air compressor or blower may be made to play into
the chamber along with the flame. w Fig. 3 indicates an air jet pipe connection
from a compressor or blower.
The apparatus can be mounted on wheels or be provided with carrying handles
if so desired.
The apparatus may be employed for heating the boilers of steam launches and
in this case I may place one or more burners at suitable situations in the fire box.
By allowing the gases to mix with coke or other loose carbonaceous substance a
powerful heat is generated and steam made quickly.
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
consider novel and desire to claim is :
1. An apparatus suitable for smoke testing drains and the like constructed and
operating substantially as herein before described with reference to the drawings
annexed.
2. The arrangement of apparatus for use as a plumbers' forge, substantially as
herein before described with reference to the drawings annexed.
