Improvements in Apparatus for Carburetting Air or Producing
" Air-gas."
A communication by the Firm of GEBRÜDER BUXBAUM, of Würzburg, in the
Empire of Germany, Machine Makers.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., Agent for Foreign Patent
Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, 118, New Street, Birmingham, in the County of
Warwick, and 322, High Holborn, in the County of Middlesex, 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 present invention refers to an apparatus for carburetting air by which
'air-gas" is produced from gasoline. The invention has for its object a new
arrangement in apparatus of this kind whereby the now used filling or car-
buretting materials are dispensed with. These carburetting materials as is
known distribute the gasoline and produce a quick evaporation of the same.
The invention consists in arranging in the interior of the apparatus beneatli
the gasoline reservoir a, a number of annular plates 6 which have an inclined
under surface c (Fig. 2 detail).
These plates are arranged one over another in zig-zags, so that the gasoline
overflowing one of these plates is caught by the next one. The carburetting or
generation of "gas" is performed in the following way.
The scoop-wheel d, e lifts the gasoline from the tank on to the uppermost
plate, from whence the same overflows to the plates arranged beneath, finally
collecting in the basin f. By a pump 9 the gasoline is pumped back occasionally
into the tank w.
Owing to the under surface of the plates c being inclined the gasoline upon
flowing over the plates does not drop directly onto the plates beneath, but
trickles along these inclined surfaces to the rim h (Fig. 2) and drops from
there onto the next plate beneath. The dotted line in Fig. 2 sliows the course
the gasoline takes on flowing through the apparatus. This overflowing and
trickling of the gasoline takes place in all parts of the apparatus at the same
time. whereby a great and energetic evaporation of the gasoline is produced.
The arrows in Fig. 1 show the direction of a current of air generated in
the known manner by the drum . This current of air touches upon the planes
of evaporation and to, (Fig. 2) for the gasoline and conducts the volatile
parts of the latter into the pipe i.
Fig. 3 shows a regulator by which the air and the "gas" obtained from the
gasoline are energetically mixed and the ratio of air and gas controlled. k
and are the inlet-pipes for the " gas "and air. A single slide or valve with
apertures is provided for the two pipes and this valve can be easily moved
and regulated according to a graduated scale o. Under the joint or single exit
opening of both pipes a laterally perforated partition is arranged and below

page_text: the same a second one perforated in the centre. Under the second partition
there is arranged a third one r which is again laterally perforated.
The outlet-pipe for the "gas" mixture is fixed on the under end of the
apparatus.

This arrangement of the partitions deflects the draught of air and gas in the
direction of the arrows whereby air and "gas" are energetically mixed.
The slide m can be suitably shifted or regulated so that the relative area of
the openings of the gas" pipe and air pipe may be altered according as more
or less of "gas" or air is required in the mixture.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondents, I declare that what I claim is:—
1. Apparatus for carburetting air or generating air-"gas" in which the
interior plates (6) for the gasoline have their under surface (c) so much inclined
that the gasoline in overflowing from one plate to another trickles along the
under surfaces of the same, whereby great planes for an energetic evaporation
are produced substantially as described.
2. In a
gas" and air mixing pipe the arrangement of slide with openings
by which the ratio of air and gas mixed is controlled substantially as described.
