COMPLETE SPECIFICATION.
A Carburating Apparatus for Autocar Motors and like purposes.
I, GUSTAVE NORGA, of 46, Rue des Riches, Claires, Brussels, in the Kingdom of
Belgium, Journalist, 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:-
All carburators actually used for driving autocar motors are constructed on the
principle of the vaporization of petroleum spirit by means of a forced draught of
air.
It follows that when the lighter portions of the spirit are vaporized, the car-
buration is no longer in the required condition for the mixture, so that the motor
slackens at first and afterwards ceases to act at all. Other inconveniences might
be mentioned.
With my carburator, represented in the accompanying drawing in which Fig. 1
is a front view and Fig. 2 an end view, both in elevation, these inconveniences do
not exist. Indeed it is constructed in such a manner that an increase of the
density of the hydrocarbon used (gazoline for instance) has no effect as the liquid
is continually being mixed raised and utilized so that the density is without
sensible variation.
Moreover the air instead of being aspirated and having to traverse a layer of
petroleum spirit, or other carburet simply passes upward into the pathway of the
hydro-carbon vapours produced by the continual rotation of the discs A. These
discs A are fixed on an ordinary shafting H revolving in bearings appropriately
formed in the covers C of the receiving chamber 1) containing the carburetted
liquid E.
The air destined to be carburetted traverses a zone impregnated with the spray
of the petroleum spirit raised paddle-wise by the perforated rotating discs.
My carburator has this special advantage over all others namely that it allows

me to produce at will a gas either very rich, moderately rich or poor.
can increase or diminish the number of discs according to whether it is desired to
produce a rich or poor gas or by increasing or diminishing the fibrous materials
on the buckets fixed on the discs, I can increase or lessen the evaporation of the
liquid.
The discs are covered with fibrous material or even with buckets which turn
over or overflow according to requirements.
By my system the air is supplied by any mechanical means such as a ventilator,
pump or the like. I reserve to myself, however, the right to supply it by any
automatic means.
The air enters by the pipe F into the receiving chamber D, passes along the
cylindrical partition to the top of the carburator, enters the pathway of the hydro-
carbon vapours produced by the continual revolution of the discs A, is then
immersed to a certain depth in the hydrocarbon liquid and arrives saturated with
these hydrocarbon vapours at the other extremity of the carburator and escapes
by the pipe G.
My carburator is preferably constructed of sheets of galvanized iron but it

trated in the drawing although it may be of any other form or size. The shape
or dimensions do not affect the principle. The carburator might for instance be
arranged to act vertically.
The revolving movement of the discs A contained in the carburator D is
obtained by a strap on the shaft H. The apparatus can be recharged with spirit
from a barrel or tank, the revolving movement can also be operated from the
shaft of the motor or by any other appropriate means.
In the application of my autocar system there is a notable economy and the
certainty of a regular working.
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
I claim as my invention a carburator especially applicable for autocars, charac-
terized by its ability to produce a gas, rich or poor as required, in which the
density is so regular that it is especially suitable to be used for the motive power
of vehicles, substantially as herein described and set forth.
