PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Raising and Lowering Pumps in
Mine or other Shafts.
We, HENRY DAVEY, of No. 3, Princes Street, Westminster, in the County of
London, Civil Engineer, ARTHUR HERBERT MEYSEY-THOMPSON and HUGH LUPTON,
both of the Sun Foundry, Leeds, in the County of York, Engineers, and JAMES
ALFRED TOWLER, of 1, Cromer Road, Leeds, in the County of York, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to means of raising and lowering pumps in mine or other
shafts, preferably utilising for that purpose the head of water in the rising main
of the pump.
We suspend the pump by a rod or several of these, each being screw threaded
for part of its length and provided with a nut which bears preferably on balls
or rollers, on a base plate supported on a girder or other framing. On the same
framing we arrange Pelton wheels, turbines or water. pressure engines with suitable
gear by which the nut is turned or when there are several nuts they are turned
simultaneously.
In order to simplify the operation of raising or lowering the pumps we pre-
ferably provide two turbines or water engines arranged to revolve in opposite
directions so that by merely opening the supply valve of the one or the other,
the pumps are raised or lowered.
Also, in order to provide for the increasing load as pipe after pipe is added
to the rising main, we may provide an additional turbine or engine or several
of these which can be brought into operation when required.
In cases where steam is readily available, a steam engine or several of these may
be substituted for the turbines or water engines.

page_text: 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 means of raising and lowering pumps in mine or other
shafts as we shall describe referring to the accompany drawings. Fig. 1 is
a side view and Fig. 2 is an end view of apparatus according to our invention
worked by a steam or other engine. Figs. 3 and 4 are corresponding views of
a Pelton wheel applicable instead of an engine.
Referring first to Fig. 1, A is an engine provided with reversing gear; BB are
two clutches; CC are two worms; D D are two worm wheels carried preferably
on ball bearings and screwed internally to act as nuts on two long screws E E.
The apparatus is carried on a bed plate H.
Either or both of the clutches B B can be engaged with the worms C C so
that, when the engine is in motion, either or both the worm wheels D D are
caused to revolve and thus either or both of the screws E E can be raised or lowered,
raising or lowering the pumps which are hung from the screws E E by links F F
a little shorter than the range of the screws E E so that when the pumps are
raised or lowered to the full extent of which the screws admit, the screws can
be disconnected and reversed and links removed or introduced as required. Where
electric power is available, an electric motor or motors may be substituted for the
steam engine A, or where hydraulic power is available, a Pelton wheel, turbine or
In such
other water pressure engine may be substituted for the steam engine A.
cases, in order to simplify the operation of raising or lowering, we preferably
provide two Pelton wheels K or water engines, arranged to revolve in opposite
directions, so that by merely opening the supply valve of the one or the other the
pumps can be raised or lowered.
Also in lowering pumps in order to provide for the increasing load, as pipe after
pipe is added, we may provide an additional turbine or water engine or several
of these, which can be brought successively into operation when required.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
Apparatus for raising or lowering pumps in mine or other shafts, arranged and
operating substantially as described and illustrated.
