PROVISIONAL SPECIFICATION.
Improvements in or connected with Vaporizers for Oil Engines.
ARTHUR BARKER Engineer 184 Malta Street Clerkenwell London E.C. do
hereby declare the nature of this invention to be as follows :-
My invention relates to an improved method of obtaining the oil vapour free
from deposit in oil engines.
I employ a vaporizer which consists of an outer tube, which is heated by a lamp..
This tuba encloses an inner tube underneath which is a metal disc, usually at an
angle. The inner tubo is perforated, and may or may not be encircled by wire
coils.
The oil is sprayed through a valve on to the said disc. This again sprays the
oil through the heated outer tube. The inrush of air caused by the outstroke of
engine piston draws the partly vaporised oil into the innor tubo, where it is further
converted into vapour by being in contact with this tube which receives heat from
the outer tube.
The vapour is then carried through the air chamber, aud exploded by hot tube.
or other suitable means.

Improvements in or connected with Vaporizers for Oil Engines.
I, ARTHUR BARKER, 13ª Malta Street Clerkenwell, London, E.C. do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertaiued in and by the following
statement :-
My invention relates to means of obtaining in a simple and effective manner the
oil vapour employed in an oil motor engine in such a manner as to avoid deposit in
the cylinder. For this purpose 1 employ a vaporiser which I shall describe
referring to the accompanying drawings. Fig. 1 is a part longitudinal section of
the cylinder with vaporiser according to my invention. Fig. 2 is a transverse
section of the vaporiser.
An outer tube A having within it a tube B perforated with small holes along its
upper side is fixed across a chimney C so ns to be heated by a suitable lamp placed
at the lower part of the chimney. A duet D closed by a conical valve E-which
is held to its seat by a light spring, leads from an oil reservoir at a higher level.
Within the tube A is fixed an inclined disc F' of such size ns to leave around it a
parrow passage. The tube B. opens into a passage G which is screw threaded at
its lower end to receive a regulating cock or valve and which communicates with
the engine cylinder K by an opening closed by a valve H held to its seat by an
adjustable spring S. When a heated tube is used for igniting the cylinder charge,
this tube T may be arranged as shown in the chimney C so as to be heated by the
same lamp as that which heats the vaporiser.

page_text: The vaporiser operates as follows:
When the engine piston makes its outward charging stroke, the valve H opens
admitting air to the cylinder and a partial vacuum being created in the whole
passage G and tube A, the valve E opens and a charge of oil enters by the duct D,
becomes dispersed in spray around the edge of the valve E and is again dispersed
around the edge of the disc F. The dispersed oil is converted into vapour in the
tube A and this vapour free from liquid oil, enters the tube B by the perforations
on its upper side and passes into the passago G and mixes with the air entering the
cylinder past the valve H.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A vaporiser for an oil motor engine constructed and operating substantially as
described with reference to the accompanying drawings.
