Improvements in Apparatus for Carburetting Air for Motors
Employing Liquid Hydrocarbons.
I, WILLIAM PECK, F.R.A.S., F.R.S.E., Astronomer to the City of Edinburgh,
City Observatory, Calton Hill, Edinburgh, North Britain, 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 means for carburetting air to form an explosive mix-
ture for use in motors, and consists of a drum, or body, which operates in a
chamber containing the liquid hydrocarbon employed, and having a space through
which the air to be carburetted is drawn by the suction stroke of the motor, the
drum, or body, alternately entering the hydrocarbon and taking up a portion
thereof into the space through which the air passes, so that it comes in contact with
the said hydrocarbon and is thereby efficiently carburetted. A float is provided
by means of which the supply of liquid hydrocarbon is automatically controlled.
In the accompanying drawing I have shewn, in sections at right angles to each
other, an arrangement according to my invention, but I do not limit myself to
the precise details illustrated. C is a chamber containing, at its lower part, the
liquid hydrocarbon, (which I will refer to as "oil"); L indicates the level of the
hydrocarbon, which is maintained by means of a float 1, contained in an external
chamber communicating with the chamber C, by the passage f, the oil being
contained in a reservoir R, from which it passes through a valve f², controlled by
the float F, so as to supply oil from the reservoir R, to the chamber C, to maintain
the level therein. 1) is a drum made of wire gauze Y, or the equivalent, the said
drum being mounted on a shaft H, turning in bearings in the sides of the
chamber C, and driven from the cam shaft of the motor by a band passing over
the pulley P.
The chamber C has openings A, and E, at its upper part, each of which openings
is controlled as required by sliding doors J, J, or adjustable valves, for allowing
the requisite amount of air to be drawn in by the suction strokes of the motor.
The air can be directed to and from the upper part of the drum D by guides a, e.
To keep the oil at a uniform temperature and ensure regularity of vapourization
there may be a space, such as W, at the bottom, or sides, or both, of the cham-
ber C, through which heated water can be passed from the water jacket of the
cylinder to the cooling tank.
At the suction stroke of the motor the air passes into the chamber C, at A, and
through the upper part of the drum D, and thence out of the chamber C, by E,
which leads to the inlet valve of the motor. As the drum revolves its lower
part passes through the oil in the chamber C and, by the continued rotation of the
drum, oil is carried up by it and the air which passes through the upper part of
the drum becomes chargeil with oil vapour to a degree in accordance with the rate
of revolution of the drum. As the oil is thus used the float F; descends and allows
a supply of oil to pass, froin the reservoir R, into the chamber C, to maintain the
level therein.

page_text: Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. In apparatus for carburetting air for motors, a drum, or body, actuated by
the motor, and moving alternately through liquid hydrocarbon and through a
space through which the air to be carburetted is drawn; substantially as herein-
before described.
2. In apparatus for carburetting air for motors; a drum, or body, actuated by
the motor, and moving in a chamber so that it alternately passes through liquid
hydrocarbon contained in the said chamber and through a space through which the
air to be carburetted is drawn, and a regulating float to control the supply of
hydrocarbon to the said chamber; substantially as hereinbefore described.
8. In apparatus for carburetting air for motors, a drum, or body, actuated by
the motor and moving in a chamber so that it alternately passes through liquid
hydrocarbon, contained in the said chamber, and through a space through which
the air to be carburetted is drawn, the hydrocarbon in the said chamber being
heated by a water space, or jacket, and the supply of hydrocarbon being controlled
by a float; substantially as herein before described.
4. An apparatus for carburetting air for motors, the said apparatus being
constructed, or arranged, substantially as herein before described and illustrated
in the accompanying drawing.
