○ Improvements in Tanks for Hydrocarbon Burners.
JOSEPH HENRY MATHEWS, of No. 45 South Market Street, in the City of
Canton, in the County of Stark, and State of Ohio, United States of America,
Metallurgist, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
My invention relates to improvements in tanks for hydrocarbon burners, and
consists in providing devices by which the temperature of the hydrocarbon to be
consumed may be raised, and to a limited extent vaporized in the tank, to produce
pressure by which the fluid is driven from the tank to the burner with such force
as to supply the required amount to the burner, and to obviate the necessity of an
air blast.
The object of my invention is to supply to a burner a fluid blast of great power
for use in assaying ores, also for use in laboratories, dental offices, and jewellers'
shops, which will operate for a number of hours consecutively, inexpensively and
of itself.
With these ends in view, my invention relates to certain features of construction
and combination of parts as will be hereinafter described and pointed out in the
claims.
The accompanying drawing represents a side elevation, partly sectional, of a
hydrocarbon tank illustrating my invention.
A indicates the tank, which may be made of any suitable material, and of any
desired dimensions, to contain a given amount of gasoline or other suitable hydro-
carbons, having at its bottom portion a through pipe B provided with apertures a
by which the fluid may enter the pipe without sediment, so liable to form in such
fluids, and so fatal to the operation of burners suitable for the uses herein before
referred to.
C represents a burner which may be of the form shown, or of any of the well-
known and approved generator vapor burners; is a valve by which the supply
of hydrocarbon to the burner is regulated.
I have, for the purpose of this application, shown the supply pipe B extended
across and out from opposite sides of the tank A, for the purpose of heating two
furnaces, but as the capacity of the hereinbefore described devices to supply the
pressure, as well as the fluid, is unlimited, many pipes may radiate from said tank
to as many furnaces, all of which may be attended by one person, who may at the
same time assay several samples of ore.
The particular feature of my invention relates to the provision of an outside
tank jacket D, which consists of cylindrical portion placed about and spaced from
the tank A, as shown, the bottom of the cylinder being perforated to pass over the
tank to which it is secured either with solder or rivets.
The top of the said jacket projects a distance above the top portion of the
tank, as shown, the two parts being secured in position at the top portion by the
stays c.
Pipes e and project upwardly from the top portion of the tank A, as shown,
the former having an inlet through which the hydrocarbon is supplied, said pipe e
having a turn valve g, to close, and the latter having a key or pet cock h, through
which the air or gas may escape while filling.
A small burner E is placed under the jacket, as shown, receiving its supply of
gasoline from the pipe B.
In operation, the tank A is filled with gasoline or other light hydrocarbon, and
the jacket filled with water about and over the top of the tank. The burner E

being lighted, the flame directed against the bottom portion of the jacket will raise
the temperature of the water in the jacket, and about the tank, to a desired degree
of temperature indicated by a thermometer. By means of the warmed body of
water, the gasoline is warmed and vaporized, to produce a pressure in the tank,
which pressure drives the gasoline to the burner with great force, producing a
greater volume of heat, uniformly maintained, and in every way giving a better
result, and at a low cost.
The cut away portions j and n show an interior portion of the tank A, and the
cut-away portion m shows an interior portion of the jacket.
The tank may be scaffolded, as shown in the drawing, or placed upon a table
-adapted to be raised or lowered.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with a hydrocarbon tank, of a water jacket surrounding
the upper portion of said tank and having its base projecting laterally beyond
the sides of the tank, a burner pipe in communication with said tank and burners,
one of which is located beneath the said laterally projecting base of the water
jacket, to heat the water contained therein.
2. The combination with a hydrocarbon tank, of a water jacket surrounding the
same, a supply pipe projecting from the top of said tank, a valve to close said
pipe, an air or gas escape pipe, a cock for closing it, a pipe in communication with
said tank, and burners C and E, the latter of which is arranged to direct its flame
against the water jacket!
