Improvements in Torches or Vapour Burners applicable for Lighting.
and Heating.
I, JOHN GRAHAM, of 4, Chestnut Street, Jamaica Plain, in the City of Boston,
in the State of Massachusetts, United States of America, Merchant, do hereby.
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained, in and by the following
statement:-
-
My invention relates to a device more or less portable and adapted to be used
as a torch or for heating purposes, and consists of an oil tank of peculiar con-
struction mounted upon an openwork cup containing oil-saturated asbestos or
some similar material; a perforated tube centrally located passes through both
the cup and the tank, and is arranged to supply air for combustion, and also to
admit oil from the oil tank to mingle with the inflowing air and add to the flame,
and thus greatly to enhance the heat production.
I have illustrated my invention in the accompanying drawings, in which
Fig. 1 shows my invention in elevation.
Fig. 2 shows the same in vertical section.
In the drawing. A represents the oil tank, which may be made of any desired
size and form. The upper part of this tank has small holes D¹. D', through
which jets of gas may escape and become ignited. Oil or other inflammable
liquid is introduced to the tank by the supply pipe B, the flow being regulated by
the stop cock B. The lower part of the tank A is surrounded by a packing of
asbestos or some similar absorbing material, which is held in the cup R.
This cup R is made with large and numerous openings, as shown in Fig. 1, and
is held to the oil tank A by means of the tube E, which is provided with a screw
thread at K and a collet at L, the screw thread engaging with the lower part of
the tank A, and the collet abutting against the bottom of the cup R.
Oil is supplied to the asbestos in the cup R by the pipe M. which enters the
cup and passes around the lower nart of the tank, as shown at M' (Fig. 2). This
pipe has numerous perforations N N, which allow the oil to pass through
and to saturate the packing in the cup R. The amount of oil admitted to the
pine M is regulated by the cock M².
The tube E passes through the centre of the device, and is provided with sets of
air holes E¹
E at its lower end, and below the cup it also has holes K¹
K', which admit vapor or gas from the contents of the packing of the cup R
to pass into the interior of the tube and become ignited. A series of inclined
openings F . . . F is made in the tube, through which oil in the tank A may
flow when the oil has reached the required level.
The operation of my device is as follows: The tank A is filled up to the level
of the holes F. F. and a sufficient quantity is admitted to the asbestos in
the cup R to saturate it. The oil in the asbestos is ignited, and a flame imme-
diately envelopes the entire device; soon the vapor passing into the tube E
through the openings K¹
K becomes ignited and assists the exterior
flame in heating the oil in the tank A, and as this oil becomes heated, it generates
Pris 1

page_text: vapor, which, passing through the perforations D₁¹. . . . D¹, also becomes ignited,
and acting with the flame from the asbestos, creates a large body of intensely
heated flame.
When the ignition has reached a certain point, an excess of oil may be turned
into the tank A, so as to cause the oil to flow through the inclined openings F
F and into the tube; this oil will be converted into an inflammable vapor,
and will at once create a fierce flame that will burn with great heat and intensity
from the top of the tube.
The supply of oil may now be cut off from the asbestos or other packing in the
cup R, and the amount flowing into the tank regulated to suit the requirements
of the user.
Under certain conditions, the device may be used without the aid of the oil
pipe M M for instance, oil may be allowed to flow into the tank to such a
degree as to overflow and run out of the perforations D¹. . . . D¹ and down
through the openings C1 C₁ into the packing in the cup R and saturate it.
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
1st. In a vapor burning device; an oil tank perforated as described; and partly
located in the upper part of a cup containing absorbent material; the said cup
and absorbent material; a central tube passing through the said cup and tank and
perforated as described; and means for supplying oil to said cup and tank; sub-
stantially as and for the purpose set forth.
2nd. In a vapor burning device, an oil tank placed immediately above a
receptacle containing absorbent material: a centrally located perforated tube
adapted to supply air for combustion as described, and having inclined perfora-
tions adapted to admit oil from the oil tank to the interior of the said tube;
and means for supplying oil to the said tank and absorbent material; substan-
stantially as and for the purpose set forth,
3rd. In a vapor burning device, an oil tank perforated as described; a per-
forated cup containing absorbent material partly enveloping said oil tank; a
perforated oil supply tube curved around said oil tank and in the absorbent
material; and means for supplying the device with oil; substantially as and for
the purpose set forth.
