COMPLETE SPECIFICATION.
Improved Pumping Apparatus for Raising Water from Wells, Tanks,
and the like.
I TEMULJEE DHUNJEEBHOY of Surat, Bombay Presidency, India, Mill
Manager, 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 said invention relates to an improved arrangement of machinery to be worked
by manual labour for drawing water from wells tanks caissons and the like. A
special advantage of my said invention is the ease with which it may be arranged
for pumping from different depths.
In order that my said invention may be more clearly understood I will describe
the same with reference to the accompanying drawings in which
b
Fig. I shows a vertical section of a well w to which my said invention is applied.
6 is a beam or sole plate fixed to the side of the well below the water level. c is a
single acting force pump secured to the sole plate 6 provided with a delivery pipe p
carrying the foot valve fv. The ram r of the pump works in guides 99 on the
sole plate. When the ram is raised the pump barrel will fill and on the descent
of the ram the water will be forced upwards through the delivery pipe p as is well
understood. The ram is raised by manual labour as hereinafter described and is
connected by a rope or chain ¹ to the lifting gear. The descent of the ram and
the consequent lifting of the column of water in the delivery pipe p is effected by
gravity. A weight barrel wb fixed on the ram contains a number of loose weights
so that the total weight of the ram may be adjusted to suit the height to which the
water has to be raised. The total effective weight of the ram and weight barrel
must of course be sufficiently great to overcome friction and to lift the column of
water in the delivery pipe p.
For raising the ram by manual labour I use the arrangement of levers and crank
gear shown in side elevation and in front elevation in Fig. II.
pp are upright posts fixed in the ground and carrying the pivots of the
levers.
sl are swinging or pendulum like levers which when propelled by manual labour
oscillate on pivots in the posts p¹. The upper ends of the swinging levers transmit their
motion through the connecting rods c', the rocking levers rl, the pitmen c¹ c', and
cranks to the flywheel fw which by means of a belt rope or the like drives the
pulley p² on the shaft of which is a crank and pitman from the lower end of
which a rope or chain r¹ reaches to the upper end of the ram r.
s is a spring or buffer from which the swinging levers sl recoil towards the
person actuating the apparatus who propels the swinging levers away from
himself.
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 1
claim is―
The hereinbefore described combination of mechanism for raising water in which
the oscillations of pendulous levers swung by manual labour acting through a system

page_text: upward delivery of the water is effected by the descent of the ram and its weight
-barrel under the action of gravity substantially as set forth.
