Improvements in and relating to Carburetting Apparatus particularly
applicable to Petroleum Engines, Oil Engines and the like.
I, AUGUSTE HENRI LOUIS GRIVEL, of 6, Rue des Poissonniers, Neuilly (Seine),
France, Engineer, do hereby declare the nature of this invention to be as follows:
This invention has reference to carburetting apparatus and is particularly
applicable to petroleum engines, oil engines and the like.
The characteristic feature of my improved apparatus is the arrangement of a
drum within a cylindrical or other shaped chamber within which it is adapted to be
rotated, this drum being in the form of a casing of perforated sheet iron, wire
gauze or other foraminous material filled with porous material such as pumice
stone, wadding or felt and mounted upon a perforated axle to permit of the entrance
and radial diffusion of the petroleum or the like.
The liquid is led in at the centre of the drum, and is projected at the periphery
in a state of fine division into a current of air supplied to the outer chamber by
any suitable means, such for example as by the movement of the motor piston or
pistons.
The drum is preferably of star shape in cross section or otherwise formed with
wings in order to present as large a surface as possible to the air current and
consequently effect a better division of the liquid. It may be driven by a pulley
from one of the shafts of the motor.
The drum may be constructed in any suitable manner; it might be in the form
of a block of porous material such as brick or terra cotta, and be mounted as before
upon a perforated axle.
The agitation produced by the movement of the drum effects a perfect admixture
of the petroleum or oil vapor with the air.

France, Engineer, do hereby declare the nature of this invention and in what
[Price Sd.]

in and by the following statement:-
-
This invention has reference to carburetting apparatus and is particularly
applicable to petroleum engines, oil or gazoline engines, spirit engines and the like.
The characteristic feature of my improved apparatus is the arrangement of a
drum within a cylindrical or other shaped chamber within which it is adapted to be
rotated, this drum being in the form of a casing of perforated sheet metal, wire
gauze or other foraminous material filled with porous material such as pumice
stone, wadding or felt and mounted upon a perforated axle to permit of the entrance
and radial diffusion of the petroleum or the like.
The liquid is led in at the centre of the drum, and is projected at the periphery
in a state of fine division into a current of air supplied to the outer chamber by
any suitable means, such for example as by the movement of the engine piston or
pistons.
The drum is preferably of star shape in cross section or otherwise formed with
wings in order to present as large a surface as possible to the air current and
consequently effect a better division of the liquid. It may be driven by a pulley
from one of the shafts of the motor.
Reference is made to Figures 1, 2, 3 of the accompanying drawings which
illustrate my improved carburetting apparatus respectively in longitudinal section,
cross section, and horizontal section.
Upon the shaft O is mounted a drum A of perforated sheet metal or wire gauze
enclosing a suitable porous material. The shaft O is formed with perforations
communicating through a longitudinal passage a¹ with a pipe B which is attached
to the shaft and through which the carburetting liquid is supplied from a convenient
receptacle.
The flow of this liquid into the apparatus is capable of being regulated by means
of a needle-valve D according to requirement.
The air to be carburetted is drawn by the suction of the piston or pistons of the
engine into the chamber C through the box which contains a number of
perforated washers or plates x.
The number of these perforated washers or plates depends on the length of the
admission and on the richness of the mixture., The air when carburetted or
charged with the vapour of the carburetting liquid passes out of the apparatus
through the pipe c.
The drum A may be constructed in any suitable manner; it might be in the form
of a block of porous material such as brick or terra cotta, and be mounted as before
upon a perforated axle.
The agitation produced by the movement of the drum effects a perfect admixture
of the petroleum or oil vapor with the air.
My improved carburetting apparatus may be arranged to work in any desired
position, horizontally, vertically or obliquely.
Figure 4 is an elevation of a vertical arrangement of the same. In either case
the apparatus should always be fitted with a device for regulating the inflow of the
carburetting liquid.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
1. A carburetting apparatus comprising a drum preferably of star-shape in cross
section, formed of or containing porous material, and adapted to be rotated within
an outer chamber, whereby carburetting liquid supplied by a pipe to the centre of
the drum is projected from the periphery of the drum in a state of fine subdivision
suitable for forming an intimate mixture with the air in the outer chamber,
substantially as described,

page_text: 2. The improved carburetting apparatus constructed and operating substantially
as herein before described and illustrated by the accompanying drawings.
