Improvements relating to Deep Well and other like Pumps.
I, JAMES RALPHS, of Wixhill, under Red Castle, near Preston Brockhurst, in the
County of Salop, Mechanic, do hereby declare the nature of this invention to be as
follows:-
This invention consists of improvements relating to deep well and other like
pumps, my object being to construct and arrange two or more pump barrels with
their plungers or buckets and valves suitably for operation from one common
handle, lever, or crank shaft, and in such a manner that the water can be raised to
the required height by stages, thus distributing the work, and thereby reducing the
intensity of the force required to perform the same.
In the application of my invention to the construction of a three stage pump, I fix
one pump barrel in the well or other required position at a height above the surface
of the water not exceeding the limit of suction lift. The bucket fitted within this
barrel is worked by a suitable rod connected at its upper end with the handle, lever,
or crank shaft of the pump body or of the gearing at the surface of the well. On
the upstroke of the bucket the water is delivered into a cistern fixed adjacent to the
barrel, and from this cistern the water is forced by the atmospheric pressure up the
suction pipe of a second pump barrel on the up-stroke of the bucket working within
the same. From the second or upper barrel the water is lifted by the bucket to the
body of the pump at the surface of the well, and is discharged through a spout or
delivery connection in the ordinary manner.
The bucket of the second or upper pump barrel is worked by a rod connected at
its upper end with the handle, lever, or crank shaft, upon the opposite side of the
pivot pin, or of the shaft, to that on which the first or lower pump rod is connected.
Thus whilst one pump bucket is making its down stroke, the other is ascending.
I make the intermediate cistern of sufficient capacity to hold a quantity of water
rather greater than the displacement area of the lower pump bucket or plunger,
and I preferably make the displacement of the lower pump bucket rather greater
than the displacement of the upper bucket, in order to ensure that there shall be
always sufficient water in the intermediate cistern to completely fill the displacement
area of the upper bucket.
For wells of great depth I son:etimes employ three or more pump barrels with
plungers and necessary fittings, arranging them all for working from one common
lever or crank shaft and in such a manner as to distribute the work of raising the
water to the required height.
I arrange for driving or operating the lever, or crank shaft of my improved
pump by manual or animal power, or by a steam or gas engine, or a wind, water, or
other motor that may be available for the purpose.

Improvements relating to Deep Well and other like Pumps.
I, JAMES RALPHS, of Wixhill, under Red Castle, near Preston Brockhurst, in
the County of Salop, Mechanic, 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 consists of improvements relating to deep well and other like
pumps, my object being to construct and arrange two or more pump barrels with
their plungers or buckets and valves suitably for operation from one common
handle, lever, or crank shaft and in such a manner that the water can be raised to
the required height by stages, thus distributing the work, and thereby reducing the
intensity of the force required to perform the same.
In the accompanying sheet of explanatory drawings to be hereinafter referred to―
Figure 1 is a sectional elevation representing a deep well pump as constructed
and arranged in accordance with my invention.
Figure 2 is an end view of the upper or surface portion of the pump.
The same reference letters in the different views indicate the same parts.
I fix one pump barrel such as A in the well or other required position at a height
above the surface of the water B not exceeding the limit of suction lift. The
bucket fitted within the barrel A is worked by a rod D connected at its upper
end with the rod E which is connected to the crank pin on the gear wheel F
mounted on the surface standard G. On the up-stroke of the bucket C the water
is delivered into a cistern H. fixed adjacent to the barrel, and from this cistern the
water is forced by the atmospheric pressure up the suction pipe of a second pump
barrel J on the up-stroke of the bucket K working within the same. From the
second or upper barrel J the water is lifted by the bucket to the body or standard G
of the pump at the surface of the well, and is discharged through the spout or delivery
connection in the ordinary manner.
The bucket K of the second or upper pump barrel is worked by a rod L connected
at its upper end with the lever M, which has its opposite end connected with the
rod N attached to the crank pin on the gear wheel F to which the rod E is also
connected as herein before described. Thus whilst one pump bucket is making its
down stroke, the other is ascending and the work of pumping is distributed.
I make the intermediate cistern H of sufficient capacity to hold a quantity of
water rather greater than the displacement area of the lower pump bucket or
plunger, and I preferably make the displacement of the lower pump bucket C
rather greater than the displacement of the upper bucket K, in order to ensure that
there shall be always sufficient water in the intermediate cistern H to completely
fill the displacement area of the upper bucket.
For wells of great depth I sometimes employ three or more pump barrels with
plungers and necessary fittings, arranging them all for working from one common
lever or crank shaft and in such a manner as to distribute the work of raising the
water to the required height.
I arrange for driving or operating the surface mechanism of my improved pump
by manual or animal power, or by a steam or gas engine, or a wind, water or other
motor that may be available for the purpose.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed, I declare that what I
claim is;-
1. The improved construction and arrangement of pump barrels with operating

page_text: mechanism and an intermediate tank or tanks for the purpose of distributing the
work of raising the water to the required height, substantially as described.
2. A deep well or similar pump constructed and arranged substantially as and
for the purposes described and as illustrated in the accompanying drawings.
