Improvements in Vaporizers for Petroleum Motors.
1, JOHN ALBERT WEYLAND, of Bellmansgatan 6, Stockholm, in the Kingdom
of Sweden, 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 :-
My invention relates to vaporizers for petroleum motors, in which the vaporization
is effected by means of the products of combustion escaping from the motor
cylinder, provision being also made if required for heating the air, with which
the vaporized petroleum is to be mixed in order that an explosive gas may be
obtained.
In the accompanying drawing,
Figure 1 is a section of a vaporizer constructed according to my invention, and,
Figure 2 is a similar view shewing the vaporizer in combination with an
arrangement for heating the air.
I will first describe my invention by reference to Figure 1 in which A and B are
two vaporizing chambers, the former which is intended to be heated by means of
a suitable flame, and the latter which during the working of the motor is heated
by the products of combustion escaping from the motor cylinder, the said two
chambers being located one behind the other, so as to constitute parts of one and
the same conduit through which the petroleum must pass in order to reach the
motor cylinder. The chamber A, which is provided with a number of inner and
outer flanges to absorb the heat, by means of a packing C of non-conducting
material insulated from the adjacent parts of the conduit in order that the heating
of the said chamber may be more quickly effected. The chamber B consists of a
pipe placed in a jacket D with its ends tightly fitting the same so as to form in the
jacket an enclosed space surrounding the chamber B to which there is an
inlet at E and an outlet at F for the products of combustion from the motor
cylinder.
The arrangement represented in Figure 2 is similar to that shewn in Figure 1
except that the jacket D contains a second pipe B', serving as a heater for the
air. From the pipe B¹ the air is conducted to a chamber A located at the side of
the vaporizing chamber A and separated from the latter, in which chamber A¹ the
air is heated by the same flame which effects the vaporization of the petroleum
when starting the motor. The air heated in this chamber A' cannot meet the
vaporized petroleum until after it has passed through the chambers A and B or
come immediately in front of the suction valve of the motor in order that no ignition
may take place in the vaporizing chambers.
•
When a petroleum motor, provided with my improved vaporizer is to be started,
the vaporizing chamber A is first heated by means of the separate flame, which,
after the motor has commenced to run is allowed to burn until the vaporizing
chamber B is sufficiently heated, whereupon the said flame is extinguished and the
vaporization exclusively effected in the chamber B heated by the products of
combustion from the motor cylinder.
The principal advantage of this arrangement consists in its simplicity of
construction, no particular arrangement being needed for conducting the petroleum
through any of the vaporizing chambers, as it must always pass through both,
and when the first chamber is no longer required to serve as a vaporizing chamber,
it is only necessary to extinguish the flame.

page_text: 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 petroleum motors in which the vaporization of the petroleum is effected
at starting by means of a vaporizing chamber heated by a flame and after starting
by means of a vaporizing chamber heated by the products of combustion from the
motor, arranging the two said vaporizing chainbers one against the other so
that they constitute parts of one and the same conduit, through which the
petroleum must pass on its way to the motor cylinder, substantially as hereinbefore
.described.
2. In combination with the arrangement claimed in the preceding claiming
clause a conduit arranged at the side of the vaporizing chambers and in a similar
way, which conduit at one end communicates with the atmospheric air and at
its other end with the conduit formed by the vaporizing chambers and serves
as a heater for the air, which is to be mixed with the vaporized petroleum
in order to obtain an explosive gaseous mixture, substantially as herein before
.described.
3. The improved vaporizers for petroleum motors herein before described and
illustrated in the accompanying drawing.
