I EDWARD GRUBE, Engineer of Albertstrasse 9, Hamburg in the Empire of
Germany 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:
This invention relates to gas or vapour burners, in which the gas for feeding the
burner is generated from a mineral oil or liquid hydrocarbon by the heat of the
burner and it consists in certain improvements in the construction of such burner
whereby the interior of the burner may be easily accessible for cleaning.
Coke and other more or less solid obstructions are usually deposited within the
pipes or retort of the burner during the process of burning, and these adhere to the
sides of the pipes etc. and impair the generation of gas from the oil so that
the interior of the burner is often clogged to such an extent as to need cleaning after
several hours of burning.
In constructions known hitherto, this cleaning process was rendered difficult,
because the opening of the retort was very troublesome and the interior of the pipes
thereof could not be opened for inspection."
The improved construction is represented in the accompanying drawings in
which
Fig. 1 is a side elevation and Fig. 2 an end view of the burner. Fig. 3 represents
the separated parts of the same. Fig. 4 is a sectional view illustrating a
modification.
The oil enters the burner at a under pressure and leaves the same as gas at 6 where
it is ignited. The reduction into gas takes place within the retort A by the heating
of the latter and the construction of this retort is the most essential feature of this
invention.
The retort A consists of the annular pipes R R R of which there may be three or
more or less than three. Each of these pipes is composed of two annular halves r
and r¹.
Of these latter the edges of the part have annular bevelled flangest which fit
into the corresponding edges of the part r¹ and are ground to fit vapour tight into the
latten

page_text: The interiors of the pipes R R R are connected each to the next by channels u as
shown in Fig. 3 placed relatively to each other to cause a zigzag passage of the oil as
indicated by the arrows in Fig. 1.
It will be seen that with the exception of the two outer annular semicircular pipe
sections, the sections r and r¹ are fixed in pairs, back to back and connected together
by pillars, one of which forms the channel u aforesaid. On the two outer sections,
lugs are cast, perforated for the passage of the bolts ss¹ with nuts for screwing up
the bolts to firmly fix the sections together as shown in Fig. 1.
For the purpose of cleansing the interior of the burner the bolts's s¹ are loosened
and the burner is taken apart, (Fig. 3) by which all the pipes are opened and readily
accessible in the most simple and perfect manner.
The tightening of the parts can also be done effectively according to the
modification shown in Fig. 4. Instead of the bevelled flanges t, each part ris
provided with a straight flange m set accurately against one another when the
bolts s s are screwed up.
The burner is brought into action by heating the same as soon as the oil is admitted
under pressure.
By heating the retort A, the gas is developed, which issues at b and
when alight produces a long flame F. As soon as the burner is at work it is heated
by the flame F itself.
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
In gas generating burners.
1. The construction of the retort A of annular pipes formed each of separable parts rrl
and held together by screw bolts or the like substantially as and for the purpose set
forth.
2. The retort A formed of annular pipes each pipe consisting of separable annular
parts said parts connected in pairs substantially as described with channels u as set
forth.
