We, PETER HEINRICH GUSTAV AHRIENS-CLAUSEN and WILHELM JULIUS NICOLAUS
KRUGER, Machinists, at Hamburg, Bei den Huetten, 70, in Germany, do hereby
declare the nature of this invention to be as follows:-
With all up to date known carburating-devices, destined for carburating of air
passing through them, there obtained the great drawback, that the carburating
liquid, generally petroleum or a carburet of hydrogen, was gradually cooled down
by the admitted air and thus rendered less efficacious.
Considering that by a carburation of this kind, representing a purely mechanical
intermixture, a continually equal effect is only obtainable if the proportions of
the mixture remain always the same, a method had to be found out, by means of
which the carburating body i.e. the liquid carburet of hydrogen, is continually to
be maintained at a temperature adequate for a sufficiently efficacious volatilization.
Such a device is the object of the present invention.
A hot-air-motor, which may be replaced by a gas-motor, is coupled with an air-
pump. The pump drives the produced current of air through the carburating
liquid. The carburating-apparatus, containing the carburating liquid is sur-
rounded by a larger recipient, filled with water. The motor is fitted with a jacket
connected above and below with the recipient of the carburating apparatus by
means of two conduits.
When working the apparatus there will be a continual water circulation towards
the cooling-jacket of the motor and back to the recipient of the carburating-
apparatus, the result being that the warmth gradually imparted to the water by
the motor, will be adducted to the carburating recipient communicating to the
liquid a somewhat higher temperature, but only up to a certain limit, as the con-
tinually entering cold air will cause a proportionate absorption of heat, so that
the water returns to the motor sufficiently cooled down.

Improvements in Carburetting Apparatus.
PETER HEINRICH GUSTAV AHRIENS-CLAUSEN and WILHELM JULIUS NICOLAUS
KRUGER, Machinists, Hamburg, Bei den Hutten, No. 70, Germany, do hereby
declare the nature of this invention and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement:-
With all up to date known carburating-devices, destined for carburating a
current of air passing through them, there obtained the great drawback, that the
carburating liquid, generally petroleum or a carburet of hydrogen, was gradually
cooled down by the admitted air and thus rendered less efficacious.
Considering that by a carburation of this kind, representing a purely mechanical
intermixture, a continually equal effect is only obtainable if the proportions of the
mixture remain always the same, a method had to be found out, by means of which
the carburating body i.c. the liquid carburet of hydrogen, is continually to be
maintained at a temperature adequate for a sufficiently efficacious volatilization.
Such a device is the object of the present invention, as represented in the annexed
drawings.
A hot-air-motor A which may be replaced by a gas-motor is coupled with an air-
pump B. The pump drives the air through the return-valves C into the pipe D
leading to a pressure-regulator E.
This pressure-regulator is formed by a bell E¹ dipping with its open end in
water or any other adequate liquid. The outer recipient E2 is closed, so that the
pressure of the passing air operates upon the surface of the liquid in E¹ forcing
it backward accordingly, the air-chamber E3 in the outer recipient serving as a
buffer, thus causing a gentle compensation of the pressure fluctuations.
The air-conduit 1) leads into the real carburating-apparatus. The carburating-
apparatus consists of two superposed compartments Fi and F2 connected by an
overflow-pipe F³.
The liquid carburet of hydrogen poured into the upper compartment fills it
up to the height of the overflow-pipe, the exceeding liquid passing through the
pipe into the lower compartment F2.
The water-gauges F4 and F5 will allow of a control. The tube D forms with
its end near the bottom of the recipient F¹ a hollow-ring G provided with a number
of small outlet-holes.
The emitted air is subtly distributed, getting enriched, on passing through the
liquid of this recipient i.e. the liquid carburet of hydrogen, by volatilized parts
of the latter. Through the tube G₁ the produce thus obtained passes into the
lower recipient F2. The outlet of this tube is shaped in the same manner as that
of the tube D, forming the hollow-ring G2 with small outlet-holes; a further
enrichment taking place in the same way.
The produce ready for use enters thereupon the pipe H the feeding pipe H¹
for the motor issuing there from.
The carburating-apparatus F is surrounded by a larger recipient I filled with
water. The gauge-cock I¹ is destined for a control. The motor A is fitted with
a jacket J connected above and below with the water-tank I by means of the
conduits K and K¹.
When working, the apparatus there will be a continual water circulation
through K towards the cooling-jacket J of the motor and through K¹ back to the
water-tank I, the result being that the warmth gradually imparted to the water
by the motor, will be adducted to the carburating recipient F communicating to
the liquid a somewhat higher temperature, but only up to a certain limit, as the
continually entering cold air will cause a proportionate absorption of heat, so
that the water returns to the motor sufficiently cooled down.
A pump of smaller size L is destined for supplying the carburating recipient
with fresh carburet of hydrogen in proportion to its consumption, out of the
tank M.
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:
A device for carburating an air current produced by a hot-air-motor or a gas-
J

carburating liquid being given an adequate evaporating temperature in so far as
the cooling-jacket J of the motor A is connected with the water containing
jacket I of the carburating recipient F by circulating-pipes K, K¹ so that the
heat supplied by cooling the motor-cylinder is communicated to the carburating-
apparatus, where in consequence of the fresh air entering into it this heat is
withdrawn from the water, which thus cooled down returns to the motor, sub-
stantially as described and for the purpose set forth in the foregoing specification.
