COMPLETE SPECIFICATION.
An Improved Pumping Apparatus and Accompanying Plant for
Raising Liquids from Mines.
I, EMIL KASELOWSKY, of 17/18 Chaussee Strasse, Berlin, 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 :-
This invention refers to power-plants used in mines for raising liquids, as water
or brine, from the bottom of the same up to any higher place, or to the surface
respectively. My improvements in such plants refer especially to that kind, in
which the water-motor arranged within the mine, and driving the pump, is driven
itself by a force-pump arranged on the surface of the earth, or within the shaft-
house respectively. My improvements relate, first, to the combination with the
conduit leading the pressure-water from the force-pump afore mentioned, to the
pump on the ground of the mine, of two accumulators acting as regulators, and
arranged one within the shaft-house, the other on the ground of the mine; and
second, to the combination with the conduit leading the waste-water from the mine-
pump back into the feed-tank for the force-pump, of an accumulator also acting as
a regulator, and arranged also on the ground of the mine. The purpose of my
invention is to prevent entirely the arising of shocks within the conduits afore
mentioned, and to make it thereby possible to use high speed engines of corre-
spondingly smaller dimensions.
The engines used hitherto for raising liquids from mines were to work with but
low speed, as each change of stroke of the piston or pistons respectively caused the
water-column to come to a standstill. In engines, in which a perfect standstill
of the water is prevented by opening the ports of another cylinder before those of
the cylinder just working are closed, there is still a more or less considerable altera-
tion of velocity of the water, so that a decrease of the intensity of the shocks is
attained, but the latter are not hindered from coming into existence at all. There
is no distributing-device existing, by which alterations in the velocity of the water
are wholly prevented. This can be attained only by providing the conduits with
regulating accumulators, as will now be more fully described.
In order to make my invention more clear, I refer to the accompanying
drawings, in which similar letters denote similar parts throughout the different views,
and in which :
Fig. 1 shows the arrangement of the various pumps, engines, and regulating-
accumulators on the surface as well as within the mine, the respective part of the
latter and the shaft being in section.
Figs. 2 & 3 show two details.
The steam-engine a arranged in the shaft-house of the mine receives steam from
boiler b, and drives the pump c, which also has its place within the shaft-house.
This pump sucks water from tank d, and delivers the same through pipe e into the
small, lower cylinder of the first accumulator; plunger g of this cylinder is
connected by means of piston-rod h with piston within the large, upper cylinder k,
into which latter steam is admitted by pipe 1. The water contained within
cylinder 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 small lower cylinder fl
of the second accumulator k, Figs. 1 & 3, the large piston i¹ of which is put under
pressure by steam or air led into the large cylinder from above through pipe .
The water after having passed cylinder f¹ enters through pipe m² pump n,

page_text: 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 piper into the channels through which the water or briue is led away.
The waste-water of motor n, which is delivered back into tank d afore mentioned,
is led by pipe t¹ through the small cylinder of the third accumulator k*. The
construction of this accumulator is the same as that shown in Fig. 3. The large
cylinder of accumulator is also connected with air- or steam-pipe . The pipes
or conduits mr and t are arranged within shaft u.
If, now,
the speed of the engine increases from any reason, and pump c, thus,
delivers more water, or if the speed of motor n becomes slower respectively, the
plungers of the three accumulators will be lifted in a corresponding degree (Figs. 2
& 3), and will be pressed down again as soon as the speeds of the various parts of
the combination have become normal again. That is to say, the capacity of the
respective waterways increases with any increase of pressure, or decreases with any
decrease of pressure respectively, so that the velocity of the water is kept on a
normal state.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, 1 declare that what
.I claim is
1. In a power-plant for raising liquids from mines by a water-motor arranged
within the mine, and driven by a force-pump arranged on the surface, the combina-
tion with the conduit connecting said force-pump with said water-motor, of two
regulating accumulators inserted into said conduit, one at or near the commencement,
the other at or near the end of the same, substantially and for the purpose as
.described.
2. In a power-plant for raising liquids from mines by a water motor arranged
within the mine, the combination with the force-conduit and the waste-conduit of
said water-motor, of two regulating accumulators inserted into said conduits, one at
or near the end of the force-conduit, the other at or near the commencement of the
waste-conduit, substantially and for the purpose as described.
3. In a power plant for raising liquids from mines by a water motor arranged
within the mine, and driven by a force-pump arranged on the surface, the combina-
tion with the conduit connecting said force-pump with said water-motor, and with
the conduit connecting said motor with the feed-tank of said pump, of two regu-
lating accumulators inserted into said conduits, one at or near the commencement of
one conduit, the other at or near the commencement of the other conduit, substan-
tially and for the purpose as described.
4. In a power plant for raising liquids from mines by a water motor arranged
within the mine, and driven by a force-pump arranged on the surface, the combina-
tion with the conduit connecting said force-pump with said water-motor, and with
the conduit connecting said motor with the feed-tank of said pump, of three regu-
lating accumulators inserted into said conduits, the first at or near the commence-
ment of the force-conduit, the second at or near the end of the same, the third at
or near the commencement of the waste-conduit of said motor, substantially and
for the purpose as described.
