The arrangement itself may be constructed. variously. Its cross-section may be
cylindrical, square, polygonal and it may be constructed horizontal, inclined, or
vertical.
+
In the accompanying drawing a horizontal cylindrical.. vessel is. represented.
which may for instance be arranged upon wheels and may serve for various
purposes as for instance a cesspool evacuator, watering cart, fire..extinguishing
engine or the like.
The vessel k carries a dome or chamber a in which is a pans, which is adapted
to receive a volatile combustible such as benzine or the like.. The latter is stored
in a vessel r with an outlet, the cock of which is actuated by the lever and hand
pull or in any other suitable manner. Below the outlet of vessel r the measuring
vessel m is provided, which serves to first measure. the. requisite quantity of, com-
bustible liquid: A second cock is provided between the measuring vessel mand.the
pipe m' leading to the pan s and is connected through a lever to. the, hand pull t
and thus to the former cock h in such a manner that when the. one opens, the other
will close. By this means a certain measured quantity. of combustible liquid can
be supplied to the pan s. Said combustible becomes vapourized in the vessel k and
forms together with the oxygen of the air in said vessel a combustible. gaseous
mixture:
This latter is then ignited by any suitable. means for instance by a flame or
priming or electricity. In place of the volatile combustible..liquid, a gas or other
substance igniting with explosion, can be used with equal success..
In the annexed drawing a lamp arranged outside the vessel k serves as the
igniting; medium, the flame of which lamp burns inside the. hollow plug of the

page_text: Through a port 'arranged in the vessel k the inner space of said vessel k can be
set in communication with the flame of the lamp. For this purpose the plug of
the cock is provided with a pinion t which engages with a rack bar z.
Fig. 2 shows the port i shut by the plug of the cock. A turning of the latter
around an angle of 180° will bring the respective port in the plug of the cock and
the port in communication so that the gaseous mixture in the inner space of the
vessel k is ignited. The air in the vessel k is thus intensely heated and expanded;
the valve and cover dare suddenly opened and after the surplus expanded
gases have escaped, these parts close again, so that owing to the rapid cooling down
of the gas which still remains in the interior of the vessel a reduction below the
requisite atmospheric pressure is almost instantly produced.
In consequence of this arrangement no floats for opening and closing the valves
are necessary since said valve v and the cover d, abruptly opened by the explosion
of the gaseous mixture, close again by their cwn weight which may be increased by
spring pressure.
If the stop-cock (a slide e in the annexed drawing) provided in the suction tube
is now opened then the vessel will in proportion to the vacuum within it
rapidly suck up water or other liquid through the hose or the like u' connected
to the tubular piece u, and previously suitably arranged to be supplied with said
liquid.
For discharging the sucked in liquid from the vessel k the necessary amount of
air is supplied to the latter by opening the ignition cock t.
If the slide e is then opened, the charge flows out whilst air enters above it
through the ignition cock t. The gas generated over the pan s previously again
filled with its charge of combustible liquid measured by the measuring vessel m
is thus uniformly distributed in the vessel k and intimately mixed with the
entering air.
In case the vessel k should not have become sufficiently filled by the first
operation and if new atmospheric air is wanted for providing for a renewal of
the vacuum then the cover d and valve » can be easily opened by hand.
upon
If the vessel k is intended for use as a watering cart it is mounted
wheels and provided with the usual pipes S, SI, with means for opening and closing
the communication between said pipes and the interior of the vessel k.
Such cart may likewise be easily used as a fire extinguishing engine and need
then only be provided with a force pump. The suction tube may for instance
be connected to the cap 2 of the orifice u or the force pump may be mounted
directly on the vessel k."
Moreover the vacuum produced in the vessel may be utilized in such a way that
in co-operation with the super pressure of the atmosphere, the cart may be
automatically propelled.
A method of construction suitable for this purpose is as follows:-
The rear wheels of the cart are keyed ou an axle A which is rotarily journalled
and on which a spur wheel Z is provided which engages with another spur
wheel Z' the shaft W of which latter is actuated by machinery analogous to a
steam engine and consisting of a cylinder with piston moving therein and a
valve gear. A pipe R corresponding to the exhaust pipe of the steam engine
leads near the ignition cock t into the vessel k. It can be closed at will by cock or
valve H.
If the pressure in vessel is reduced, the outer atmospheric pressure acts upon
the piston surface in the cylinder since the pipe R' corresponding to the supply
pipe of steam engine communicates with the outer air. The piston consequently
receives a reciprocating movement and will thereby set the spur wheel Z¹ in rotary
motion which latter motion is transmitted through the spur wheel Z to the axle A
of the rear wheels and thus to the latter themselves.
When the difference of pressure at the face and at the rear of the piston has
diminished to about atmosphere, then the vessel is again evacuated which may be
done while the apparatus moves forward.

page_text: The cart may of course be provided with means for steering and with a brake to
be actuated from the coach box or otherwise.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a suction device for drawing in liquids comprising a vessel closed with
anti return valves, the method consisting in supplying a volatile combustible liquid
and evaporating the same in the interior of said vessel (k) to form with the oxygen
of the enclosed air an inflammable gaseous mixture and igniting the same so as to
produce an explosion for the purpose of generating a vacuum in said vessel and
opening an orifice therein communicating with a free supply of liquid.
2. The method as above described, as varied by the replacement of the volatile
combustible liquid by a gas or any other substance capable of igniting under
explosion.
3. In a suction device for drawing in liquid a closed vessel k without any float
devices in which an abrupt opening of anti return valves is effected by the explosive
ignition of a combustible matter.
4. The combination of the means for drawing in liquids as described with
supporting wheels and water distributing pipes (S, S¹).
5. A vehicle comprising a device for drawing in liquids as described in combi-
nation with a propelling mechanism actuated by the difference of pressure between
the exterior and interior of vessel k for automatic propulsion of the vehicle
substantially as and for the purpose set forth.
