I, GEORGE CROYDON MARKS, of 18, Southampton Buildings, Chancery Lane,
London, W.C., Consulting Engineer (a communication from Alfred Bouvier, of
Laval, in the Republic of France, Engineer) do hereby declare the nature of this
invention to be as follows:
My invention relates to improvements in vaporisers for oil motors, and has for its
object to provide an uniform supply of oil and a complete admixture or vaporisation
of the oil particles necessary to produce a combustible charge.
My invention consists of a vaporiser in which the oil supply is admitted into a
secondary reservoir where upon the level reaching a certain limit the supply is cut
off by means of a float valve, and in which the oil passes from the secondary reser-
voir to a conical nozzle along the exterior sides of which air is permitted to pass for
admixture with the issuing oil particles, the intimate admixture being further
attained by means of a vane wheel which upon the suction stroke of the engine is
caused to rotate by the passage of the oil particles and air, and in the passage of
which the intimate association of the oil and air is attained.
In carrying my invention into effect I provide a secondary reservoir into which oil
is supplied preferably at the centre of its upper surface, a valve being provided
which seats upon the extremity of the oil supply aperture and is provided upon a
float which upon the level of the oil reaching a certain limit effects the closure of the
oil supply aperture and regulates the supply, so that the level in the secondary reser-
voir is practically constant. The oil is taken from the reservoir to a conical nozzle
through which the oil passes issuing out through the nozzle into a mixing chamber.
The nozzle is provided with spiral grooves which cause a gyratory movement of the
air upon the suction stroke which has the effect of insuring the association of
the air with the oil particles. A conical annulus is preferably provided around the
nozzle for the admission and passage of air, and superposed immediately above the
nozzle is a vane wheel which, on the suction stroke, is caused to rotate and on rota-
tion effects the further intimate admixture of the oil particles and air,
The vane wheel is preferably mounted within the mixing chamber upon a spindle
one end of which is carried upon a plate, the centre portion of which plate acts as
a deflecting surface against which the oil is injected. I provide a separate supple-
mentary air inlet to the mixing chamber so that the quality of the mixture may be
regulated to suit requirements. The mixture of oil and air is taken from the
mixing chamber to the engine cylinder upon the suction stroke of the engine.
I do not confine myself to the provision of spiral grooves upon the injecting nozzle
and a conical annulus for the admission of air and for effecting its gyratory move-
ment, as it is obvious that the grooves may be provided upon the interior surface of
the casing into which the injecting nozzle projects, and that the conical annulus

required.

I, GEORGE CROYDON MARKS, of 18, Southampton Buildings, Chancery Lane,
London, W.C., Consulting Engineer (a communication from Alfred Bouvier,
Engineer, of Laval, in the Republic of France), 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 vaporisers for oil motors, and has for its
object to provide a uniform supply of oil and a complete admixture of vaporisation
of the oil particles necessary to produce a combustible charge.
The accompanying drawing is a vertical longitudinal section of my improved
vaporiser illustrating the method of carrying my invention into effect.
My invention consists of a vaporiser in which the oil supply is admitted into a
secondary reservoir where upon the level reaching a certain limit the supply is cut
off by means of a float valve, and in which the oil passes from the secondary reser-
voir to a conical nozzle along the exterior sides of which air is permitted to pass for
admixture with the issuing oil particles, the intimate admixture being further
attained by means of a vane wheel which upon the suction stroke of the of the
engine is caused to rotate by the passage of the oil particles and air, and in the
passage of which the intimate association of the oil and air is attained.
In carrying my invention into effect I provide a secondary reservoir A into which
oil is supplied preferably at the central pipe B placed on its upper surface, a valve f
being provided which seats upon the extremity of the oil supply central pipe B as
shown and is provided upon a float F which upon the level of the oil reaching a
certain limit effects the closure of the oil supply pipe's aperture and regulates the
supply, so that the level in the secondary reservoir A is practically constant. The
oil is taken by way of a pipe C from the reservoir to a conical nozzle D through
which the oil passes issuing out through the nozzle into a mixing chamber G. The
nozzle D is provided with spiral grooves d which cause a gyratory movement of
the air upon the suction stroke which has the effect of insuring the association of the
air with the oil particles. A conical casing E fixed a short distance off the nozzle ])
forms an annulus around the said nozzle for the admission and passage of air, and
superposed immediately above the nozzle is a vane wheel T which, on the suction
stroke, is caused to rotate and on rotation effects the further intimate admixture of
the oil particles and air. The air inlet from the atmosphere in the first instance is
through a port or passage H leading to the annulus.
The vane wheel T is preferably mounted within the mixing chamber G upon a
spindle K one end of which is carried upon a plate L, the centre portion of which
plate acts as a deflecting surface against which the oil is injected. I provide a
separate supplementary air inlet R to the mixture chamber so that the quality of
the mixture may be regulated to suit requirements. The mixture of oil and air is
taken from the mixing chamber G to the engine cylinder upon the suction stroke of
the engine by way of the port J.
I do not confine myself to the provision of spiral grooves upon the injecting nozzle

page_text: and a conical annulus for the admission of air and for effecting its gyratory move-
ment as it is obvious that the grooves may be provided upon the interior surface
of the casing into which the injecting nozzle projects, and that the conical annulus
may be dispensed with and the grooves made larger than otherwise would be
required.
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 vaporisers for oil motors the provision of a spirally grooved annulus in com-
bination with a revolving vane operated on the suction stroke of the engine through
both of which the air is drawn; as a means for producing an intimate admixture of
oil spray or vapour injected into the vaporiser underneath the said wheel with the
air all substantially as and for the purposes herein before described.
2, The improved vaporiser for oil motors substantially as and for the purposes
herein before described with reference to the accompanying drawings.
