We PHILIP TEAGUE, Mechanical Engineer and WILLIAM HENRY THOMAS,
Merchant, both of Neath in the County of Glamorgan do hereby declare the
nature of this invention to be as follows:-
This invention relates to the means and apparatus by which the slants or other
depressions in collieries, mines, or in other places, may be effectively drained, or by
which water or other liquid may be pumped or forced from one locality to another.
The invention consists in the application or utilization of the weight and non
compressibility of liquids (which are probably their best known properties) for the
production of such power as will operate a pump by means of which the draining
or other desired effect will be produced, and this we accomplish by means of the
following arrangement of parts it being assumed for convenience of illustration
that it is desired to remove the water collected at the bottom of a slant or any
other depression.
At a higher level than the top of the slant is a tank or reservoir (or other
means may be employed which will give a supply of water under pressure) The
pipe from this source of supply is provided with suitable valves, by means of
which a regulated quantity of water may be passed from under an air vessel
if desired, through an equilibrium valve, and thence down the slant pipe where the
pressure raises a ballast box or weight, attached to which is the pump ram, which
rising with the ballast box draws in enough water from the sump to fill the pump
cylinder.
While this action has been taking place at the bottom of the slant, the pressure
from the water supply has also raised a second ballast box or weight at the top of
the slant, Attached to this second ballast box is a plug rod or other actuating
source, by means of which the arm of a tilting lever or pendulum-bob is gradually
thrown over, and this action through connected levers is made to close the
equilibrium valve, as regards the supply under pressure, and to open the eduction
branch or valve box. The pressure in the slant pipe being thus reduced, the

page_text: ballast boxes both fall owing to the action of gravity, and the water used in lifting
ballast boxes, together with the water pumped from the sump is discharged at the
glant head.
As the top ballast box falls, the attached plug rod acting on the lever or
pendulum-bob closes the eduction branch and opens the supply pipe through the
equilibrium valve and the entire operation is repeated. It being clearly under-
stood that one of the principal features of our invention, consists in the arrangement
by which a single line of piping is used for conveying the power to the pump,
and carrying the water so used together with that which is pumped to the top
of the slant. The power to work the pump may also be applied by a horizontal
pole, worked by a steam engine fixed at the surface of colliery.

We PHILIP TEAGUE Mechanical Engineer and WILLIAM HENRY THOMAS
Merchant both of Neath in the County of Glamorgan 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 relates to the means and apparatus by which the slants, or other
depressions in collieries, mines, or in other places, may be effectively drained, or
by which water or other liquid may be pumped or forced from one locality to
another. The invention consists in the application or utilization of the weight and
non-compressibility of liquids (which are probably their best known properties)
for the production of such power as will operate a pump either alone or when
combined with steam or other power by means of which the draining or other
desired effect will be produced and this we accomplish by means of the following
arrangement of parts which will be clearly understood by reference to the accom-
panying drawings in which,
Fig. 1 represents in elevation a pump worked by hydro-dynamic power only.
Fig. 2 represents the arrangement of parts at the power generating station when
both hydro-dynamic and steam or other power are used.
Fig. 3 represents in plan view the pump and its connections and
Fig. 4 represents in plan view the cataract ram and connected parts.
It is assumed for convenience of illustration that it is desired to remove the
water collected at the bottom of a slant or any other depression and that hydro-
dynamic power only is employed.
At a higher level than the top of the slant is a tank or reservoir A (or other
means may be employed which will give a supply of water under pressure). The
pipe a from this source of supply is provided with a suitable valve b by means of
which a regulated quantity of water may be passed from under an air vessel B
(if desired) through an equilibrium valve placed in casing C and thence down the
Blant pipe D where the pressure acting on accumulator ram d working in cylinder G
raises a ballast box or weight E attached to which is the pump ram e which rising
with the ballast box draws in through the one way valve f, enough water from the
sump to fill the pump cylinder F the water from slant pipe D being prevented from
passing to the pump cylinder by means of one way valve g.
While this action has been taking place at the bottom of the slant, the pressure
from the water supply A has through pipe h also raised a second ballast box or
weight H at the top of the slant. Attached to this second ballast box is a plug
rod or other actuating source I by means of tappets i on which the arm ; of a
tilting lever or pendulum bob J is gradually thrown over, and this action through
connected levers k is made to close the equilibrium valve in C, as regards the
supply under pressure, and to open the eduction branch or valve box L. The
pressure in the slant pipe being thus reduced, the ballast boxes E and H both fall
owing to the action of gravity, and the volume of water used in lifting ballast

page_text: boxes, together with the volume of water corresponding to that pumped from the
Bump by pump F, is discharged at the slant head L.
As the top ballast box H falls, the tappet i on the attached plug rod I acts on
the arm of the lever or pendulum bob J, which through levers k, k, closes the
eduction branch L and opens the supply pipe from under B, through the equilibrium
valve and the entire operation is repeated.
Where a constant water supply as at A is not readily obtainable steam or other
power may be employed to work the pump and the necessary arrangement of parts
for this purpose is indicated in Figure 2 in which is represented a pole or piston M,
adapted to be actuated by steam or other driving power. Said pole M works in
casing or cylinder N, the capacity of which should be equal to that of the
accumulator cylinder G, and pump cylinder F. The operation with this arrange-
ment of parts is as follows, it being assumed that ballast box E and loaded valve O
are down, and the pole M at its full out stroke with slant pipe D and pole case N
full of water.
Power being applied to pole M it commences its in-stroke forcing the water
contained in the slant D into cylinder the ram of which raises ballast box E
with its connected pump piston e and thus causes pump cylinder F to be filled.
When d and e are at their full outstroke, pole M has only reached half its instroke
the remaining half of which is utilized to raise loaded valve O which is weighted
to a few pounds more per square inch than the pressure required to raise the
ballast box E, the remaining portion of water in cylinder N being then forced out
through the discharge pipe L of the loaded valve O. As the pole M travels out
the pressure is withdrawn, and the partial vacuum formed behind the pole M
causes the case N to be filled with water from the slant corresponding to the
amount discharged from under accumulator ram d combined with that pumped by
piston e, and the parts are in position to repeat their various functions. The speed
may advantageously be about 150 to 180 feet travel per minute varying the
number of strokes to suit the length of piston travel.
We wish it to be clearly understood, that one of the principal features of our
invention consists in the arrangement by which a single line of piping is used for
conveying the power to the pump, and carrying the water so used together with
that which is pumped to the top of the slant.
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
1st The arrangement of parts by which a single line of pipe suffices for con-
veying the power to the pumps and for the discharge substantially as set forth.
2nd The improved arrangement and combination of apparatus for pumping water
or other liquids substantially as described and as illustrated in the accompanying
drawings.
