IMPROVEMENTS IN HYDROCARBON STOVES
Year: 1878

page_text: LETTERS PATENT to David Pitcairn Wright, of 390, Now John Street West,
Birmingham, in the County of Warwick, Lamp Manufacturer, for the Invention
of "IMPROVEMENTS IN HYDROCARBON STOVES."
Sealed the 8th November 1878, and dated the 11th May 1878.
PROVISIONAL SPECIFICATION left by the said David Pitcairn Wright at
the Office of the Commissioners of Patents on the 11th May 1878.
DAVID PITCAIRN WRIGHT, of 390, New John Street West, Birmingham, in the
County of Warwick, Lamp Manufacturer. "IMPROVEMENTS IN HYDROCARBON
STOVES."
The object of this Invention is to obtain, along with the heat from a petroleum
burner or burners in a hydrocarbon heating or cooking stove, the bright and cheerful
appearance of an open fire-grate. For this purpose I form one or more sides or
part of sides, or front or part of front, of the stove, of tubes of glass or strips of glass,
but in every case so arranging that the lateral junction of the tubes or strips with
each other, and the junction of the same with their metal supports at the sides of
the stove, is so perfect or nearly perfect that the admission of air between the lateral
and terminal junctions of the tubes or strips is so little that when the container or
oil vessel, carrying the burner with their cone plate or plates is slidden into its
place, all the air that passes through the stove may pass through the cone opening,
or at least so large a portion thereof as may produce perfect combustion of the oil.
The arrangement of the container with burner sliding in, and of the cone and
cone plate sealing the opening from the admission of external air, is that patented
by Mr. E. A. Rippingille, Number 4137. 1875, the use of which I have purchased
the right to adopt.

the said David Pitcairn Wright in the Great Seal Patent Office on the 11th
November 1878.
DAVID PITCAIRN WRIGHT, of 390, New John Street West, Birmingham, in the
County of Warwick, Lamp Manufacturer. "IMPROVEMENTS IN HYDROCARBON
STOVES,"
The object of this Invention is to obtain, along with the heat from a petroleum
burner or burners in a hydrocarbon heating or cooking stove, the bright and cheerful
appearance of an open fire-grate. For this purpose I form one or more sides or
part of sides, or front or part of front, of the stove, of tubes of glass or strips of glass,
but in every case so arranging that the lateral junction of the tubes or strips with
each other and the junction of the same with their metal supports at the sides of
the stove is so perfect or nearly perfect that the admission of air between the lateral
and terminal junctions of the tubes or strips is so little that when the container or
oil vessel carrying the burner with their cone plate or plates is slidden into its
place, all the air that passes through the stove may pass through the cone opening,
or at least so large a portion thereof as may produce perfect combustion of the oil.
It will thus be seen that the front of this stove is arranged in such a manner that
breakage from the flame is impossible, while the light shewing through has the
agreeable effect of an open fire, and gives a certain amount of light at the same
time.
The arrangement of the container with burnor sliding in, and of the cone and
cone plate sealing the opening from the admission of external air, is that patented
be Mr. E. A. Rippingille, No. 4137, 1875, the use of which I have purchased the
right to adopt.
And in order that my said Invention may be properly understood I will moro
fully describe the same with reference to the annexed Drawings wherein,-
Figure 1 is a perspective view of my hydrocarbon heating and cooking stove;
Figure 2 is a sectional side elevation of the same.
A, A, are glass tubes or slips of glass (in this instance tubes), through which the
light from the burner B of the lamp C is seen and reflected by the concave reflector
Dattached to the back of the stove. The light from the burner B is also reflected
by the bright wings or false sides E and the false top F, and the bottom plate G in
front of the tubes.
There is in the top of the stove a circular opening covered by an ornamental
cover H, the latter is removable so that the opening can be utilized for cooking and
other purposes; there are also openings I in the top for the better diffusion of heat,
and openings J all round the lower part of stove for the admission of air for com-
bustion; K, a slight hole (covered with any suitable transparent material), so that
the condition of the burner can be readily seen.
The glass tubes are placed laterally as close together as is practicable, so that only a
very inappreciable amount of air find entrance through the interstices, in no way
affecting the legitimate part of the inward draft of air through the openings I,
thonce through the cone plate L to the burner B. The tubes A are held in position
at their ends in the metal supports M, and are cemented into the same to prevent
air entering in that direction.
Having thus described the nature and object of my said Invention, I declare
that what I claim and desire to be secured to me by the herein-before in part
recited Letters Patent is,--
First. The general arrangement and combination of parts whereby the bright and
cheerful appearance of an open fire-grate for hydrocarbon stoves is obtained by means
of a transparent curved or other shaped front placed in front of the flame in the
manner substantially as herein-before described, and shewn on Drawings.

page_text: Second. The novel and peculiar arrangement of slips or tubes of glass, as and for
the purposes substantially as herein-before described.
In witness whereof, I, the said David Pitcairn Wright, have hereunto set
my hand and seal, this Ninth day of November, in the year of our Lord
One thousand eight hundred and seventy-eight.
DAVID PITCAIRN WRIGHT. (L.S.)
