Improvements in Power-plants for Raising Liquids.
I, EMIL KASELOWSKY, of 17-18 Chaussée Strasse, of Berlin, in the Kingdom of
Prussia, German Empire Royal Counsellor of Commerce, 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 :-
My invention refers to power-plants, used in, or connected with, mines for raising
liquids, as water or brine, from the bottom of the same up to any higher place, or
to the surface respectively, and my improvements in such plants relate to the com-
bination of three pumps (one of which is employed as a motor) with each other as
well as with an accumulator acting in this case as a regulator, and the object of
this new combination is, first, to permit the employment of a high-speed steam-
engine for driving the first of the pumps, second, to allow arranging this pump and
the steam engine on the surface, and third, to avoid the arising of shocks within
the pressure-conduit, as will all be more fully described hereinafter.
In order to make my invention more clear, I refer to the accompanying drawing,
in which similar letters denote similar parts throughout the several views, and in
which:
Fig. 1.shows the arrangement of the various pumps and engines on the surface
and in the mine, the respective parts of the latter and the shaft being in section;
Fig. 2 is a vertical section through the accumulator, the piston of the same
being in its middle position.
The steam-engine a arranged in the shaft-house of the mine receives steam from
boiler, and drives the first pump c, which also has its place in the shaft-house.
This pump sucks water from tank d, and delivers the same through pipe e into the
small lower cylinder of the accumulator; plunger y of this cylinder is connected
by means of piston-rod h with piston i within the large, upper cylinder k, into which
latter steam is admitted by pipe 7. The water contained within cylinder f is, thus,
put under high pressure by the action of the steam on piston i.
This water, then, flows through pipe m down to the second pump n, which,
acting as a motor, drives the third pump o. This pump sucks the water or brine p,
that has collected on the ground of the mine, by pipe q, and delivers the same by
pipe into the channels through which the water or brine is led away. The waste-
water of motor n is delivered back through pipe t into tank d aforementioned.
The pipes mr and are arranged within shaft u.
I am, thus, enabled by my new arrangement to dispense entirely with rods in the
shaft, and I can yet arrange the steam-engine on the surface, which engine may be
a high-speed one. 1, further, get the advantage of collecting the oil washed away
by the water that is sucked and pressed through the first pump and the second
pump or motor (cand n), as the waste-water of the latter is not led into the delivery-
pipe of the third pump, but is carried upwards by a special pipe (t), and is delivered
into the same tank from which pump c is sucking. The oil, thus, collects on the
surface of the water within said tank.
If, now, the speed of the engine increases from any reason, and pump c, thus,
delivers more water, or if the speed of motor a becomes slower, the plunger g will
be lifted in a corresponding degree (Fig. 2), and will be pressed down again as soon
as the speeds of the various parts of the combination have become normal again.
The accumulator is, thus, acting as a regulator, concerning the pressure of the
water

page_text: 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 power-plant for raising liquids, the combination with a pump adapted to
drive water under high pressure into a conduit, of a motor adapted to be driven by
said water, and to drive in its turn another pump, for the purpose as described.
2. In a power-plant for raising liquids, the combination with a pump adapted to
drive water under high pressure into a conduit, of a motor adapted to be driven by
said water, and to drive in its turn another pump, the conduit between the first
pump and the motor containing a pressure-regulator, for the purpose as described.
3. In a power-plant for raising liquids, the combination with a pump adapted to
drive water under high pressure into a conduit, of a motor adapted to be driven by
said water, and to drive in its turn another pump, the waste-water of the motor
being led back to the supply-tank for the first pump, for the purpose as described.
4. In a power-plant for raising liquids, the combination with a pump adapted to
drive water under high pressure into a conduit, of a motor adapted to be driven by
said water, and to drive in its turn another pump, the first pump containing a
pressure-regulator, the waste-water of the motor being led back to the supply-tank
for the first pump, for the purpose as described.
Dated this 16th day of February 1894.
