CHARLES HENRY GREEN, of 211, Gresham House, Old Broad St., City of London,
E.C. "'AN IMPROVEMENT IN THE MANUFACTURE OF OIL STOVES."
A com-
munication from abroad by Edward Benson Cox, of the City of New York, in the
United States of America.
This Invention relates to improvements in the manufacture of oil stoves for
cooking or other purposes. First, a reservoir is constructed to contain the oil with
its top pierced by two tubes to contain wicks of usual form, and operated by means
of wheels and shafts of the ordinary form and in the usual manner. The top of
the reservoir is enclosed by a rim of convenient heighth forming a receptacle for
water to receive the heat generated by the flame and prevent its reaching the
oil; the water surrounding the wick tubes, wheels, and shafts. Above the wick
tubes a cap is placed containing two cone-shaped kerbs, one of which coincides
with each of said tubes and permits the flame to pass upwards. From the cap a
sheet-iron cylinder extends upward to a convenient heighth, and at its upper end
is enclosed by a metal head, which is provided with two openings which coincides
with the wick tubes and kerbs, but have considerably larger horizontal dimensions.
From each side of each opening a flange extends downwards and outwards. The
cylindrical cap and head are hinged to the reservoir, and an elevated support for
cooking utensils is secured to the upper end of the cylinder, the latter is supplied.
with a glazed opening or openings, thus completing the apparatus,

CHARLES HENRY GREEN, of 211, Gresham House, Old Broad Street, in the City
of London, E.C. "AN IMPROVEMENT IN THE MANUFACTURE OF OIL STOVES." A
communication from abroad by Edward Benson Cox, of the City of New York,
in the United States of America.
This Invention relates to an improvement in the manufacture of oil stoves, the
following being a description thereof :-
Fig. 1 and 2 of the annexed Drawings shew the stove as arranged for use;
Fig. 1 a side view and Fig. 2 a front view.
Fig. 3 shews the stove with the upper hinged portion turned to one side so as to
uncover the wick tubes. Fig. 4 is a vertical central section upon a line having a
right angle to said tubes. Letters of like name and kind refer to like parts in
each of the Figures.
oil.
A represents the reservoir for containing oil, which reservoir has preferably
downward and outward flaring sides, and at its upper side and outer edge is
enclosed by means of an annular flange B that has a height of about one and one-
half inch, and is used to contain cold water for receiving the heat radiated down-
ward from the burners so as to prevent the same from being communicated to the
From the reservoir A two tubes C, C, extend upward to the required distance
and serve to contain wicks D, D, of usual shape. Said wicks are moved vertically
by means of star wheels E, E, which wheels are secured upon and rotate with
suitable shafts e, c. In order that the wick wheel shafts e and e may be prevented
from becoming warped by the action of the heat, so as thereby to change the rela-
tive positions of the wicks and engaging wheel, said parts are located within suitable
housing C below the water line, by which means a perfect protection is afforded
and all liability to derangement avoided. Above and around the upper ends of
the wick tubes C, C, is placed a cap F, that is provided with cone-shaped kerbs f, ƒ,
one of which coincides with each of said tubes, and permits the flame of the burning
oil to pass upward from the wick. From the cap F, which is preferably constructed
from cast metal, a sheet metal cylinder G extends upwards about seven inches, and
at its upper end is enclosed by a metal head H, which latter is provided with two
openings h, h, that coincide in position with the wick tube kerbs f, f, but have
larger horizontal dimensions. From each side of each opening h a flange h¹ extends
downwards and causes the heated escaping gases to be deflected towards the ends
of said openings. The cylinder G, cap F, and head H, which form the chimney of
the lamp, are hinged so as to permit of being turned to one side, as shewn in Fig. 3,
a metal support or flange I projecting outwards for cooking utensils, and provided
with openings in the side so as not to interfere with the draught, is secured to the
upper end of said cylinder G; one or two glazed or tale openings are provided in
the latter completing the apparatus, the operation of which will be readily under-
stood from the foregoing description.
Having thus fully set forth the nature and merits of this Invention, what I
claim under the above in part recited Letters Patent for an improvement in the
manufacture of oil stoves is-
1st. The annular flange B, constructed as described, forming in combination with
the upper part of the oil reservoir a cold water tank.
2nd. The hinging of the cylinder G so as to permit of being turned to one
side.
3rd. The combined cap and chimney consisting of the cap F with the kerbs f
and f, the sheet metal cylinder G, and the head H provided with the openings h, h,
and flanges or flue plates h¹, h¹, depending from the sides only of said openings,
and the metal support or flange projecting outwards I for cooking utensils, all

substantially as shewn.
In witness whereof, I, the said Charles Henry Green, have hereunto set my
hand and seal, this Twelfth day of January, in the year of our Lord One
thousand eight hundred and seventy-seven.
Signed, sealed, and delivered by the said
Charles Henry Green, in the presence of
