FOR PUMPING AND HAULING IN MINES to be as follows:-
"
This Invention relates to improved apparatus for transmitting motive-power,
and is particularly adapted for use in mines, for transmitting power from the
surface to hauling and pumping apparatus in underground workings.
The improved apparatus comprises two tubes or pump barrels, which are each
fitted with a plunger or piston and piston-rod passing out through stuffing-boxes at
one end, and are connected by a transverse tube at or near the end. The plunger
or piston-rods are connected by any suitable means to cranks at right angles, or to
bell-crank levers or similar devices operated by the motive-power engine, the tubes
or barrels being erected side by side at or near the bottom of the shaft when the
apparatus is used in a pit or mine. The one plunger or piston is at one end of its
stroke while the other is at the opposite end of its stroke, and the tubes are filled
with water, and being connected at the end, the relative positions of the pistons are
maintained while they reciprocate, whether their connection with the actuating cranks
or levers at the surface be through rigid straight rods or flexible ropes or wires used
to convey the motion round curves. This apparatus, so far as described, resembles
in its general features, the pumping apparatus described in the Specification of
Letters Patent No 4059, dated 22nd November 1875. Owing to leakage of the
water within the pump barrels, and varying expansion and contraction due to
changes of temperature and like causes, the pumping apparatus therein referred to,
soon after starting became inoperative. To render the apparatus effective for
pumping purposes, and to enable it to be employed for transmitting power to
winding or hauling apparatus or similar apparatus, we maintain a constant supply
of water under pressure in the tubes, by connecting to them or to the cross tube at
the end, a small tube or pipe which is led up the shaft to a level sufficient to give
a greater pressure than the pressure due to the column pumped, plus that required
to overcome the friction involved in the working parts, and the tube terminates in
a tank or other source of supply at or near such suitable level, Or failing facilities

page_text: for obtaining such level the pressure for maintaining the column may be obtained
by a small ram or other similar apparatus worked off any of the working parts of
the pump into a small accumulator which may be provided with a safety valve to
pass off any excess of water over that required to maintain the column. The
apparatus as described acts also as a means of maintaining the tension upon the
ropes or rods, so that no jerk is produced in working, which does away with the
usual jerk upon pumps worked through rods or ropes for long distances, and so
avoids the usual wear and tear due to jerking and unsteady motion.
In applying the improved apparatus for transmitting power to hauling or
winding engines or similar machines underground, the plunger or piston-rods are
continued out through the opposite end of the tubes, and the water column is
introduced on each side of the pistons, and the rods are connected to cranks at
right angles, or to any of the ordinary devices employed for converting
reciprocating rectilinear motion into rotatory motion. When employing the
improved apparatus for pumping purposes, a breeches pipe, provided with suitable
suction and delivery valves and connections, is fitted at the side or end opposite to
that at which the liquid column is maintained between the pistons or plungers.
To enable the apparatus to be employed for pumping or raising water in two or
more lifts, the rods are continued to a lower level, being worked through a gland
at the low end of the working barrel or casing of the set above, and a second set of
pistons or plungers and rods are provided and worked in the same way as the first
A separate set of suction and delivery valves and connections are also
provided and so arranged that the water raised by the lower pumping apparatus is
delivered to that above, and is forced to the surface by the latter, or by the
uppermost of the series if there be more than two.
set.
When, as often occurs in collieries, and in mines generally, the power requires to
be transmitted to underground ways which run at various angles and inclinations
to the shaft, or which traverse curves or crooked paths, water pipes or tubes are
laid round the curves or angles until a straight lead is again got for the rods or
ropes, the pipes are laid in duplicate, and connected at each end by a transverse
tube or pipe, the two pipes then forming when fitted with four pistons or plungers,
two pairs of transmitting apparatus similar to the apparatus used in the pump and
already described, the compensating column being admitted at each side of each of
the pistons or plungers. The rods are then continued to the place where power is
required, or to the next curve, where a similar apparatus may be employed and 80
on to the different point or points. If required, the stroke of the actuating engine
may be reduced or increased at any part of the system, by employing in the
apparatus described, a pair of larger and a pair of smaller working barrels, the
difference of stroke being regulated by the difference in the sectional area of such
working barrels.

Midlothian, Agent, and ROBERT ARMSTRONG, of the same place, Engineer, (Mining)
do hereby declare the nature of our said Invention for "IMPROVEMENTS IN
HYDRAULIC APPARATUS FOR TRANSMITTING MOTIVE POWER, PARTICULARLY ADAPTED
FOR PUMPING AND HAULING IN MINES" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This Invention relates to improved apparatus for transmitting motive-power, and
is particularly adapted for use in mines for transmitting power from the surface to
hauling and pumping apparatus in underground workings.
In the accompanying drawings, figure 1 is a sectional elevation, and figure 2 is a
plan of the improved apparatus as arranged for transmitting power from the pit-
head to underground hauling apparatus. Figure 3 is an elevation and figure 4 is a
sectional plan of a modification of the improved apparatus for transmitting power to
operate pumping engines underground. Figure 5 is a horizontal section of the
pumping apparatus as fitted with rams in lieu of plungers.
The improved apparatus comprises two tubes or pump barrels A, A', which are
each fitted with a plunger or piston B, B¹ and piston rod C, C, passing out through
stuffing boxes b, b¹ at one end, and are connected by a transverse tube A² at or near
the end. The plunger or piston rods C, C are connected by any suitable means to
cranks or bell-crank levers or similar devices operated by the motive power engine
at the surface, the tubes or barrels A A¹ being erected side by side at or near the
bottom of the shaft when the apparatus is used in a pit or mine. The one plunger
or piston B is at one end of its stroke while the other B₁ is at the opposite end of
its stroke, and the tubes A, A' are filled with water, and being connected at the end
at A³ the relative positions of the pistons are maintained while they reciprocate,
whether their connections with the actuating cranks or levers at the surface be
through rigid straight rods or flexible ropes or wires used to convey the motion
round curves. This apparatus, so far as described, resembles in its general features
the pumping apparatus described in the Specification of Letters Patent N° 4059
dated 22nd November, 1875. . Owing to leakage of the water within the pump
barrels A, A¹ and varying expansion and contraction due to changes of temperature
and like causes, the pumping apparatus therein referred to soon after starting
became inoperative. To render the apparatus effective for pumping purposes and
to enable it to be employed for transmitting power to hauling apparatus or similar
apparatus, we maintain a constant supply of water under pressure in the tubes A, A',
by connecting to them or to the cross tube A' at the end, a small tube or pipe D
which is led up the shaft to a level sufficient to give a greater pressure than the
pressure due to the column pumped, plus that required to overcome the friction
involved in the working parts; and the tube D terminates in a tank or other source
of supply at or near such suitable level. Or failing facilities for obtaining such
level the pressure for maintaining the column may be obtained by a small ram or
pump or other similar apparatus worked off any of the working parts of the pump
into a small accumulator which may be provided with a safety valve to pass off any
excess of water over that required to maintain the column. The apparatus as
described acts also as a means of maintaining the tension upon the ropes or rods, so
that no jerk is produced in working, which does away with the usual jerk upon
pumps worked through rods or ropes for long distances and so avoid the usual wear
and tear and breakages due to jerking and unsteady motion.

page_text: In applying the improved apparatus for transmitting power to hauling engines
or similar machines underground, the plunger or piston rods C, C¹ are continued
out through the opposite end of the tubes A, A¹, and the water column is introduced
on each side of the pistons, and the rods E are connected to cranks F or to any of
the ordinary devices employed for converting reciprocating rectilinear motion into
rotary motion. When employing the improved apparatus for pumping purposes, a
breeches pipe G provided with suitable suction and delivery valves and connections
as shown in figure 4 is fitted at the side or end opposite to that at which the liquid
column is maintained between the pistons or plungers.
To enable the apparatus to be employed for pumping or raising water in two or
more lifts, the rods are continued to a lower level being worked through a gland at
the low end of the working barrel or casing of the set above, and a second set of
pistons or plungers and rods are provided and worked in the same way as the first
set. A separate set of suction and delivery valves and connections are also provided,
and so arranged that the water raised by the lower pumping apparatus is delivered
to that above, and is forced to the surface by the latter or by the uppermost of the
series if there be more than two.
When, as often occurs in collieries, and in mines generally, the power requires to
be transmitted to underground ways which run at various angles and inclinations
to the shaft, or which traverse curves or crooked paths, the tubes or barrels A, A'
are continued or additional water pipes or tubes are laid round the curves or angles
until a straight lead is again got, and additional plungers or rams B², B³, provided
with piston rods and connecting rods are provided. The breeches pipe G of the
pumping apparatus, or the cranks and connecting rods E, F of the hauling apparatus
are connected to the last pair of tubes A³, A₁ of the series, and the apparatus is
operated by the transmission of power through the columns of water in the tubes
or barrels A, A¹. The pipes may be laid in duplicate and connected at each end by
a transverse tube or pipe A2 the two pipes then forming, when fitted with four,
pistons or plungers, two pairs of transmitting apparatus similar to the apparatus
used in the pump already described, the compensating column in the pipe D being
admitted at each side of each of the pistons or plungers A, A¹. The rods are then
continued to the place where power is required, or to the next curve where a similar
apparatus may be employed and so on to the different point or points. If required,
the stroke of the actuating engine may be reduced or increased at any part of the
system, by employing in the apparatus described a pair of larger and a pair of
smaller working barrels, the difference of stroke being regulated by the difference
in the sectional area of such working barrels.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is,
First. The improved apparatus for transmitting motive power substantially as
herein described and illustrated.
Second. The arrangement in combination with power transmitting apparatus of
the kind herein described, of a compensating water column, as and for the purpose
set forth.
