Improved Lamp for Heating the Vaporiser and Ignition Tube of
Oil Engines.
I, EMIL CAPITAINE, of Frankfurt on the Main, in the Empire of Germany,
Civil Engineer, 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 :-
The lamps hitherto used for heating the vaporisers and ignition tubes of oil
engines in which oil is vaporised under pressure, present the disadvantage or
inconvenience that the small openings through which the oil or oil vapour flows,
are frequently subject or liable to stoppages caused by dirt and that consequently,
the workings of these engines are not reliable.
The object of my invention is to obviate this disadvantage, and it consists in
regulating the flow of the oil, not as is usually done by reducing the cross section
" pipe
of the orifice through which it flows, but by introducing a so-called "
resistance which is analogous to that used in connection with electro-motors.
The cross section of the supply pipe is uniform throughout.
The invention consists further in allowing the oil to flow on the heated surface of
the vaporiser and igniter, the vapour thereby produced being drawn through.
suitable openings by the natural or artificial air draught of the lamp and burned in
the usual manner on admission of air.
On the accompanying drawing Figure 1 shews in section the vaporising and
igniting portion of an oil engine which portion is fitted with a lamp of the aforesaid
kind. Figure 2 shews the means of regulating the flow of the oil.
A is the combustion chamber and B the piston of an oil engine. The vaporising
and igniting chamber D is attached to the wall C of the combustion chamber A.
This part is provided with a passage a jointed at each end to the chamber D and
in which the oil introduced through pipe W and valve F is vaporised and afterwards
ignited during the compression stage. The oil required for feeding the lamp of
the vaporiser is evaporated in passage 6 of chamber D. The oil for the latter is
admitted in exactly regulated quantities through pipe v and the vapour produced is
drawn down through 6¹ and up through openings 62 where it is burned, as shewn
on the drawing.
Passage b is in communication with the atmosphere and air can enter it to mix
with the evaporated oil, the action being similar to that of a Bunsen burner. At
The combustion products
the same time, air penetrates into E through openings x.
of the flame find their exit through chimney z which at the same time creates the
necessary draught for the flow of the vapour evolved in chamber b. The draught
can also be assisted by bellows or artificial blast, if desired.
Oil flows from the inverted bottle t, see Figure 2, into a vessels thence through
pipes (the "pipe" resistance) and tube v into space b. The pressure due to the
height y is reduced to almost nothing by the friction of the oil in the narrow tubes i
The cross
and the oil flows in the smallest required quantities into passage b.
section of the tubes is, however, made everywhere of such size that a stoppage
caused by impurities is, so to speak, impossible, or, at least, improbable. As a

page_text: matter of course, the greater the diameter of the tube and the proportionately
greater length of the same, the lesser the danger of its getting foul or stopped.
The difference of level must, of course, be kept almost equal in order to keep the
flame constant. This equality in the difference of level can be maintained by any
other similar and suitable devices which are used for such purposes such as that
known as the "bird fountain," and the inverted bottle is here given only as an
example.
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). In an oil engine, the regulation of the amount of oil required to keep the
lamp burning, by means of a "pipe" resistance i and the admission of the oil into
a passage 6 of the vaporising and igniting chamber D, the whole being for the
production of a heating flame.
(2). In oil engines, the combination with a passage b leading to a vaporising
and igniting chamber D, of pipes i forming a "pipe" resistance, controlled by a
level device, substantially as and for the purposes set forth.
