Apparatus for Pumping well Bores.
I, WILLIAM MATHER, of Salford Iron Works, Manchester, in the County of
Lancaster, Member of Parliament, 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 relates to apparatus for pumping water from well bores so arranged
that the pump can be readily adjusted in position and power to suit greater or less
depths of bore.
For this purpose I extend down the bore a pipe which is the delivery pipe of the
pump and in this pipe there is a spindle which is driven at the top of the well by
any suitable motor, and which works a rotary pump of special construction attached
to the pipe.
Fig. 1 of the accompanying drawings is a vertical section of the 'bore, pipe,
spindle and pump; the other figures shew to an enlarged scale the construction of
the pump. Fig. 2 being a longitudinal section partly in elevation and Fig. 3 a
transverse section shewing the revolving blades and the fixed spiral and radial
guides, the radial guides being shewu by dotted lines.
Referring first to Fig. 1, A is the pipe which extends down the bore from a

pipe, guided by suitable bearings revolves the spindle D which drives the blades of
the pump.
Water drawn up the suction pipe E Hows up the vertical pipe A and out by a
lateral branch F.
The pump consists of a number of disc shaped segments G bolted together, and
to the end segments of which are bolted respectively the suction pipe E and the
discharge pipe A. In each of the segments G there is a partition H which does
not reach to the centre but leaves an annular passage around the boss K of the
wheel. On the suction side of the partition H as shewn in Fig. 2 are radial ribs h,
on the other side there are spiral guide ribs h', and through one side of the section
there are holes h opening into the spaces between the radial ribs of the next
section in order. In each section on the one side of the partition revolves a wheel
consisting of a boss K keyed on the spindle D and a number of blades projecting
from the boss. Each blade, a section of which is shewn in Fig. 4, has its part k
which is next the boss projecting into the annular space within the partition H, the
other part revolves between the partition H and the face of the next section in
order. Water, entering by the holes 2 in the lowest section, is by the parts k of
the first set of blades caused to pass up beyond the first partition and driven by the
parts of the blades along between the spiral guides ', thence through the
holes into the next section where its rotating motion is first arrested by
the radial ribs h, and then it is again acted on by the blades of a second wheel,
thus receiving repeated impulses until it issues from the highest section into the
pipe A with sufficient pressure to overcome the column above it.
When the level of water sinks in the bore, the pipe A is lengthened and the
pump has sections and wheels added to it so as to give the water sufficient pressure
to overcome the increased column.

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 would have it understood
that I do not make any general claim to the construction of the segments and
wheels of the pump, as pumps operating in the manner described are already known,
but what I claim is :-
Apparatus for pumping well bores consisting of a delivery pipe extending
down the bore, carrying at its lower end a pump of the kind described, and
having in it a spindle on which the wheels of the pump are keyed, substantially as
described.
