IMPROVEMENTS IN HYDRO-CARBON COOKING AND HEATING STOVES
Year: 1881

page_text: LETTERS PATENT to Francis Arnold, of 390, New John St. West, Birmingham,
in the County of Warwick, for an Invention of "IMPROVEMENTS IN
HYDRO-CARBON COOKING AND HEATING STOVES."
PROVISIONAL SPECIFICATION left by the said Francis Arnold at the Office
of the Commissioners of Patents on the 11th March 1881.
FRANCIS ARNOLD, of 390, New John St. West, Birmingham, in the County
of Warwick, "IMPROVEMENTS IN HYDRO-CARBON COOKING AND. HEATING
STOVES."
In place of the single wick case with its appropriate winder and cone, or any
number thereof, each with their several separate cones and slot holes for the flame, I
arrange two or more separate wick cases parallel and in close juxta position to each
other, but so far separated that an adequate supply of air for the proper combustion
of the oil may pass not only between the two or more wick cases, but also at each
side and ends thereof.
Above these I arrange in the usual manner the cone, but sufficiently wide to
cover the two or more wick cases, and in this cone I slot an air passage of sufficient
width to allow the flames from both wick cases to pass through, but so arranged
as to size and position of the slot hole that the combustion is perfected when placed
under the draught of the chimney. The effect of this novel arrangement, through
the flames being brought into such close connection with each other and yet
subjected to a strong current of air not only on their outside but also on their insidė
surfaces, is a very great improvement in the burning and a great increase in the
heating power for cooking or heating.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Francis Arnold in the Great Seal Patent Office on the 10th September
1881.
FRANCIS ARNOLD, of 390, New John Street West, Birmingham, in the County
5 of Warwick. "IMPROVEMENTS IN HYDRO-CARBON COOKING AND HEATING
STOVES."
This Invention consists of improvements in hydro-carbon cooking and heating
stoves, and I carry out the same as follows:-
In place of the single wick case with its appropriate winder and cone, or any
TDA1

page_text: number thereof, each with their several separate cones and slot holes for the flame,
I arrange two or more separate wick cases parallel and in close juxtaposition to
each other, but so far separated that an adequate supply of air for the proper com-
bustion of the oil may pass not only between the two or more wick cases, but also
at each side and ends thereof.
Above these I arrange in the usual manner the cone, but sufficiently wide to
cover the two or more wick cases, and in this cone I slot an air passage of sufficient
width to allow the flames from both wick cases to pass through, but so arranged as
to size and position of the slot hole that the combustion is perfected when placed
under the draught of the chimney.
The effect of this novel arrangement, through the flames being brought into such
close connection with each other and yet subjected to a strong current of air not
only on their outside but also on their inside surfaces, is a very great improvement
in the burning and a great increase in the heating power for cooking or heating.
And in order that this my said Invention may be readily understood I will now
proceed to describe the same by reference to the accompanying Drawing, which
represents a sectional elevation of my said Invention at right angles to the flat
burners. a, a, is the body of the cooking apparatus as usually constructed; b, b, are
the wick cases containing the two wicks as shewn. The wicks are regulated by
the usual wheels d, d; c is the chimney; e is the cone which contains one slot for
the two flames, and the opening or slot f is so arranged that it causes the two
flames to impinge upon each other. The two currents of air passing up the inside
of the cone at g, g, impinge upon the outsides of the two flames at the two lips of
the slot in the cone, and the middle current of air g¹ impinges upon the inner
surfaces of the two flames, in consequence of such flames being brought near
together, as above described, thereby improving the combustion and economising the
fuel.
Having thus described the nature and object of my said Invention and the
manner of carrying out the same, I would have it understood that I am aware that
a dual burner of a similar kind has been in use some time as a lamp burner, and I
make no claim thereto, but that what I claim and desire to be secured to me by
the herein before in part recited Letters Patent is,―
1. The use and adaptation of dual burners with a single slotted cone for heating
and cooking purposes, substantially as herein before described and shewn on the
Drawing.
2. The general combination and arrangement of parts together respectively
forming my improvements in hydro-carbon cooking and heating stoves, substantially
as herein before described and shewn on the Drawing or any mere modification
thereof.
In witness whereof, I, the said Francis Arnold, have hereunto set my hand
and seal, this Ninth day of September, in the year of our Lord One
Witness,
HOWARD WRIGHT,
390, New John St. West,
Birmingham.
FRANCIS ARNOLD. (L.S.)
