Improved Pump.
I, WALTER WHEELER, of Railway Foundry, Langley Green, in the County of
Worcester, Ironfounder, do hereby declare the nature of this invention to be as
follows: ---
The object of this invention is to provide a lifting pump, by substituting two or
more cylinders in pump of comparatively short stroke, for the usual larger
diameter single cylinder pump of comparatively long stroke, used for lifting only;
having a head or reservoir receiving the contents of the said cylinders, with a
spout for delivery leading therefrom. In conjunction with the above body a
bottom valve box containing the valves for the cylinders coupled to single inlet
or suction pipe, the buckets working in the before mentioned cylinders being
actuated by a lever or levers working in or above reservoir and so arranged for
handle, or to be driven by power.
The small external size consequent on the short stroke multiple cylinders and
compact bottom valve box rendering this pump especially suitable for domestic
use or export.

WALTER WHEELER.
I, WALTER WHEELER, of Railway Foundry, Langley, near Birmingham, Iron-
founder, 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 improvements in lift pumps whereby increased
lifting capacity is combined with decrease of bulk of pump, thus making a smaller
pump of this principle and design equal for effective work to one of much larger
size of the ordinary class of lift pumps, effecting saving in first cost, and in
carriage for home or export. The method of accomplishing this may be seen from
the accompanying drawing. Fig. 1 represents a Front Vertical Section through
centre of pump. AA are the two barrels, B the reservoir or head into which the
contents of barrels are discharged. DD are the buckets having ways or
passages CCCC through them for water or other liquid, and retaining
valves C C C C on same.
EE are the rods attached to buckets DD, and connected with the rocking

page_text: lever Fat each extremity PP by means of joints. H is the handle being in one
piece with rocking lever F, or attached thereto. J is a valve box or chamber com-
municating with barrels A A through valve KK, and with inlet L to suction pipe.
Fig. 2 is a side sectional elevation, shewing connection of spout M with reservoir
or head B. The lettering in Fig. 2 corresponding with that in Fig. 1.
As will be seen from the accompanying drawing, the operation of pump is as
follows: The handle H working on Pivot S, and in slot I in cover R from N to O
actuates the cross lever F raising one bucket, and depressing the other, and vice
versa. The action of bucket and foot valve in cach barrel being exactly that of
the common type of simple lift pump, the alternate rise and fall of each bucket
contributes to the supply of water or other liquid in the reservoir or head B. Each
movement of handle H across slot I from N to 0, or from O to N therefore does
effective work in raising the water or other liquid, and necessarily the return stroke
of handle is not waste as in single action pumps. Further, the head being of fair
size forms a reservoir for the water or other liquid, thus securing a continuous
flow from the outlet or spout M.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. A double acting lift pump..
2. Barrels and head or reservoir cast in one piece.
All the above points being clearly set forth in the above description, and
distinctly shewn on the drawings attached hereto.
Dated this 6th day of November 1897.
