Vertical Double-action Lift and Force Pump.
I, HARRY HOLT, of 9, Chapet Street, Berkhamsted, Herts, Plumber, do hereby
declare the nature of this invention to be as follows:-
-
Barrel a of ordinary construction in iron, lead or other metal, solid piston or
plunger 6 the rod working through a packing box, the suction pipe branches
into two inlet pipes d and d' the first d is carried up the side of the barrel, nearly
to the top; where it enters a valve-chamber e and is controlled by by a clack or
other suitable valve f: an opening g level with the bottom of this chamber admits
the liquid directly into the upper part of the barrel; immediately above this
opening a second smaller opening or vent hole for air h the second inlet pipe (
enters the bottom of the barrel and is controlled by a valve f¹ an opening in the
front of the barrel, forms the lower part thereof into a valve chamber e¹ shewn in
the drawing by dotted line, there are two outlets from the barrel i and the lower
one i from the lower part of the barrel to the valve chamber e controlled by
valve from hence, the rising maine k carries the liquid into the upper valve
chamber the upper outlet 1 passes from the upper part of the barrel into the
valve chamber e³ and is controlled by the valve f³ the rising maine projects slightly
into the valve chamber thus forming a lip between the two openings, which
prevents the flow of liquid from the rising main interferind with the due working
of the valve f. From the valve chamber e³ the liquid passes dirictly through
the main outlet m. Fig. 1 shews the pump at rest, the plunger at the top of the
stroke, and all valve closed. Fig. 2 the down stroke opens the valves f and f
and closes and 3, the liquid is drawn by suction up the inlet d into the upper
part of the barrel, the same stroke forces the liquid below the the plunger, through
the outlet up the rissing main k and so out of the main outlet m.
Fig. 3. the up stroke closes the valves f and fa and opens f¹ and f³, and while
sucking the liquid through the inlet d¹ at the same time forces that above the
plunger, through the outlet ¹ and into the main outlet m.
The valve chambers e, e¹, e and e³ can be fitted with movable doors for inspection
purposes in the ordinary way.

statement:-
Barrel a of ordinary construction in iron, lead or other metal, solid piston or
plunger 6 the rod working through a packing box. The suction pipe c branches
into two inlet pipes d and d'; the first is carried up the side of the barrel nearly
to the top; where it enters a valve-chamber e and is controlled by a clack or
other suitable valve f: an opening g level with the bottom of this chamber admits
the liquid directly into the upper part of the barrel; immediately above this
opening is a second smaller opening or vent hole for air h which can be done either
with or without. The second inlet pipe d' enters the bottom of the barrel and is
controlled by a valve f¹; an opening in the front of the barrel forms the lower
part thereof into a valve chamber el shewn in the drawing by dotted line. There
are two outlets from the barrel i and the lower one i from the lower part of the
barrel to the valve chamber e controlled by the valve f from hence the rising-
main k carries the liquid into the upper valve chamber e³. The upper outlet i
passes from the upper part of the barrel into the valve chamber e³ and is controlled
by the valve f the rising-main projects slightly into the valve chamber thus
forming a lip between the two openings, which prevents the flow of liquid from
the rising-main interfering with the due working of the valve f3. From the
valve chamber e³ the liquid passes directly through the main outlet m.
Fig. 1. shews the pump at rest, the plunger at the top of the stroke, and all
valves closed.
Fig. 2, the down stroke opens the valves f and f³ and closes f¹ and f³ the liquid
is drawn by suction up the inlet d into the upper part of the barrel; the same
stroke forces the liquid below the plunger through the outlet i up the rising
main k and so out of the main outlet m.
Fig. 3, the up stroke closes the valves f and f² and opens f¹ and f³ and while
sucking the liquid through the inlet d' at the same time forces that above the
plunger, through the outlet 21 and into the main outlet m. The valve
chambers e, e¹, and e3 can be fitted with moveable doors for inspection purposes
in the ordinary way.
CLAIMS.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare what
I claim is:-
1.) The improvement in the construction of pumps substantially as and for the
purposes herein described and illustrated.
2.) The addition to an ordinary single acting vertical lift pump, with a solid
piston b substituted for the bucket, of the valves f and f the inlet pipe d and the
continuation of the rising main k working as herein before described and illustrated
and forming a double action pump.
Dated this day 28th of April 1898.
