CHARLES ADOLPHUS HENRY JONAS, of Studley Road, Clapham Road, in the
County of Surrey.. "CERTAIN IMPROVEMENTS IN OIL STOVES." A communication
from abroad by Joseph Dobinson, of New York, in the United States of America.
In oil stoves made according to this Invention the cones and flame of the stove
are surrounded by glass tubes, of variable shape, set into suitable grooves or
channels; rods connect the cone plate and the top of the stove together and guard
the glass, and gutters on the wick tubes conduct the oil that may overflow the top
of wick tubes back into the oil box. Perforated plates cover the holes where the
overflow is carried back to oil box, and tubes with perforated covers at the end of
wick tubes convey any gas generated in the oil box to the flame, thus forming:
safety tubes should the oil box become heated. A wall of glass surrounding the
wick cones, and of oblong or other form in conformity therewith, acts as a chimney
to improve the draught, and also assists in concentrating the heat in the centre;
cork or other suitable non-conductor of heat is used to prevent heat descending to
the oil box, and a very cheap and good oil box is made of sawdust or wood pulp
combined with glue, glycerine, or other suitable material.

The oil box may be circular and the tubes be set lower and not into the oil, as
shown, but the oil be supplied through pipes from the sides; these suspended wick
tubes will make the stove very safe.
A small stove with one burner may be made suitable for nurseries and small
apartments, and also a larger one with three or four wick tubes, with an iron case
or cone within them smaller at the bottom than the top, so as to contract and
quicken the draughts.

CHARLES ADOLPHUS HENRY JONAS, of Studley Road, Clapham Road, in the
County of Surrey. CERTAIN IMPROVEMENTS IN OIL STOVES." A communication
from abroad by Joseph Dobinson, of New York, in the United States of America.
In oil stoves made according to this Invention the cones and flame of the stove
are surrounded by glass tubes, of variable shape, set into suitable grooves or
channels; rods connect the cone plate and the top of the stove together, and guard
the glass; a wall of glass tubes or rods is thus formed, of oblong or other shape,
according to the shape and arrangement of the wick cones, which acts as a chimney
to improve, the draught and also assists in concentrating the heat in the centre.
Gutters are placed on the wick tubes to conduct the oil that may overflow the top
of wick tubes back into the oil box. Perforated plates cover the holes where the
overflow is carried back to oil box, and tubes with perforated covers at the end of
wick tubes convey any gas generated in the oil box to the flame, thus forming
safety tubes should the oil box become heated.
Or the wick tubes may be suspended from the frame supporting the cone plate
and glass chimney, thereby preventing the heat from descending through the wick

page_text: tubes in the oil box. By suspending the wick tubes in the oil box the heat is cut
off therefrom, the air being thereby kept cool and danger avoided; further, the hole.
in which the wick tubes hang acts as an outlet for the gases should any be formed,
permitting them to pass through the perforated tin up to the flame where they are
consumed, and thus prevented from escaping into the room and causing an
unpleasant odour. In this arrangement the gutters are dispensed with, and the oil
that flows over the wick tubes is conducted to the oil box again by running down
the outside of the wick tubes back into the oil box, the top of which is thus kept
clean. Cork or other suitable non-conductor of heat is used under the legs that
sustain the wick tubes and cone plate to prevent heat descending to the oil box.
The oil box plates and frames of this improved oil stove may be made of metal.
or any suitable material, but a very cheap and good oil box is made of sawdust or .
wood pulp. combined with glue, glycerine, or other suitable material.
A small stove with one burner may be made, according to this Invention, suitable
for nurseries and small apartments, and also a larger one with three or four wick
tubes, with an iron case or cone within them, smaller at the top than the bottom,
so as to contract and quicken the draught.
.
A hot plate is also provided whereby the heat may be directed from beneath
kettles or other heaters, placed directly over the stove through a hollow conduit
or conduits to perforations to heat other. kettles, pots, pans, or warmers placed at
the side of the stove.
The accompanying Sheet of Drawing shows an oil stove embodying these
improvements, Figure 1 being a longitudinal section through the stove; Figure 2,
a cross section through the stove; Figure 3, a sectional plan; and Figure 4, a part
plan of the top plate drawn to an enlarged scale.
In Figure 5 a modification of the above is illustrated, the oil gutters being
dispensed with and the arrangement of the wick tubes and cones altered, as shewn,
Figure 6 being a sectional plan of the above with hot plate.
Figure 7 is an elevation of a stove complete with cover on.
The dotted lines represent the arrangement adopted when three wicks are used
in lieu of two, whereby the draft is greatly increased.
A, A, are the glass tubes forming the wall of glass, acting as chimney and for
concentrating the heat in the centre.
B, B, the wick cones..
C, C, the grooves or channels for the tubes A, A, connected by the rods c, c,
which also serve to protect the glass while making the whole one moveable
piece.
D, D, the oil gutters.
E, E, the wick tubes; at Figure 5 it will be seen that they are attached to the
plate G, and are suspended in the parts f, f, of the oil box, which are open at the
top and that they do not touch the sides of f,f; in this arrangement the cutters
D, D, are not required.
F, the oil box.
G, gallery or bridge piece.

page_text: The oil box may be circular and the tubes be set lower and not into the oil, as
shown, but the oil be supplied through pipes from the sides.
Having now described and ascertained the nature of the Invention communicated
to me as aforesaid, and in what manner the same is or may be performed, I desire
it to be understood that I do not limit myself to any particular shape or dimensions
either of the whole or of parts of this improved oil stove, nor to the use of any
particular material in its manufacture excepting in so far as relates to the wall or
chimney of glass, and that what I claim as secured to me by the herein-before in
part recited Letters Patent is,-
Firstly. In an oil stove the glass tubes or rods A, A, when forming a wall or
chimney of glass of any shape surrounding the wick cone or cones, substantially as
described.
Secondly. The grooves or channels C, C, receiving the glass tubes A, A, and con-
nected by the rods c, c, substantially as described.
Thirdly. The gutters D, D, on the wick tubes E, E, for returning overflow of oil
to the oil box, substantially as described.
Fourthly. The wick tubes E, E, suspended from the plate G and entering the
oil box at f, f, substantially as shown, Figures 5 and 6, and for the purposes herein-
before set forth.
Fifthly. The gallery G with perforated plate G¹ carrying the wick cones B, B,
and supporting the glass wall or chimney, substantially as described.
t
Sixthly. When the arrangement shown, Figure 5, is not adopted the safety
tubes H for escape of gas from the oil box F to the flame, substantially as herein-
before described.
Seventhly. The cone M for quickening draught, constructed and applied sub-
stantially as described.
And Eighthly. The hot plate O for obtaining greater heating surface, as herein-
before set forth.
In witness whereof, I, the said Charles Adolphus Henry Jonas, have here-
unto set my hand and seal, this Twenty-ninth day of July, in the year
of our Lord One thousand eight hundred and seventy-eight.
