We, JOHANN MATHÄUS GROB, ALFRED OSCAR SCHULTZE, and ANTON VINCENZ
NIEMCZIK, of Eutritzsch-Leipzig in the German Empire, Merchants, 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 means for effecting the ignition of vapour in gas and
petroleum motors for which an intense flame is required and especially to a lamp fed
with heavy oil under pressure from a reservoir located above it.
The object of the invention is to suppress a serious evil in lamps of the said kind in
which the vaporisation of the oil takes place by fits and starts especially when the
flame is somewhat large, burning unevenly and frequently going out. The cause of
this is that the oil column has a to and fro movement brought about partly by the
feed and partly by the sudden formation of vapour following thereon and the forcing
back of the oil column.
Instead of a large vapour space presenting the disadvantage that the lamp must be
heated during a lengthy interval of time we apply in close proximity to the vaporising
surface an air vessel, which, every time the lamp is extinguished becomes freshly
charged with air.
The invention consists in the application to an oil lamp of an air vessel in
combination with a cock of peculiar construction for opening and shutting off
communication with the oil supply and by which at the same time the air vessel is
charged with air every time the lamp is extinguished.
In the accompanying drawing
Fig. 1 is a vertical section of the lamp with a portion of the cylinder of a gas or
petroleum motor.
Fig. 2 a section through line Y-Z of Fig. 1.
Figs. 3 and 4 sectional views of the cock with the plug of the same set in different
positions.
A is the oil supply pipe leading from an oil reservoir (not shewn) placed about
three feet higher than the lamp. B a three-way cock. Cair vessel. D vaporising
pipe only the upper end of which serves for vaporising, and which, to commence with,
is heated by a spirit flame and later by a flame at E which is the outlet for the
generated vapour. F is the igniting pipe or chamber. G chimney. H portion of
cylinder of gas or petroleum motor. I combustion space.
In the position of cock shewn in Fig. 1 the oil will flow from supply pipe A into
air vessel C where the air is somewhat compressed and thence into pipe D. Previously
however the upper part of this pipe is heated by means of a spirit flame so that oil
passing into this part of the pipe is transformed into vapour which passes out at
aperture E and to commence with, is there ignited by the spirit flame, this latter being
kept applied until pipe F and the asbestos strip N over it becomes glowing hot so as
to burn the vapour from E as this comes in contact therewith.
In the position of cock shewn in Fig. 3 the flame goes out, oil passing from pipe D
into the air vessel discharging thence through pipe g, air from the outside at the same
time passing through aperture E into pipe D and air vessel C so as to fully charge
this again.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:

an air vessel C and discharge cock B in the oil conduit and in close proximity to the
vaporising surface of the lamp substantially as described and shewn.
