Improvements in Reciprocating Wing Pumps.
I HERBERT JOHN HADDAN of the firm of Herbert & Co. Patent Agents
of 18 Buckingham Street Strand W.C. London Civil Engineer do hereby declare
the nature of this invention a communication to me from abroad by Axel Fredrik
Abrahamson of Madrid in the Kingdom of Spain Engineer and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention relatos to suction and force pumps in which the pistons are wings
projecting from a central shaft or axle to which a reciprocating motion is given and
the object of the improvements is to provide said pumps with mechanism of quadruple
or sextuple action or effect and to cause the pressure in the pump to be equally
distributed over the wings, around the central shaft or axle.
In the accompanying drawings
Figs. I II and III are sectional views of an improved pump of quadruple action,
Fig. I being a section on line A B of Figs. II and III and Fig. Il a section on
line CDE Fig. I and Fig. III a section on line C F E Fig. I.
Figs. IV V and VI are respectively similar views of an improved pump of sextuple
action.
Figs. VII and VIII are respectively sections on lines A B and C E of a modified
construction of quadruple action pump.
Figs. IX and X are similar views of a modified construction of sextuple action
pump.
The liquid drawn enters in the usual way through the suction pipe a and is expelled
through the delivery pipe a' which in the sextuple action pump in Figs. IV V VI IX
and is of a larger size at the base in order to be able to receive the liquid from the
delivery valves
and q
In Figs. I II III VII and VIII there are two wings m fitted on the axle i
and according to Figs. IV V VI IX and X three wings m fitted on the axle.
The four spaces g and h (in pumps of quadruple action) and the six spaces g and h
(in those of soxtuple action) which are formed by the wings m and the fixed heads c
and d with their valves n o p q are in communication through the passages band s
which carry the liquid either through the centre of the wings as in Figs. I II ILI IV V
and VI or through channels formed in the pump casing as in Figs. VII VIII IX
and X. In this way the spaces g are in communication through the passages band the
spaces through the passages s.
h
The manner in which these pumps act is as follows
appliable to all figures in the drawings.
Supposing that the wings m are turned in the direction indicated by the arrow e,
the liquid sucked through the valve n enters the nearest space g and the remaining
spaces g through the passages b. If afterwards the wings m are turned in the opposite
direction then the nearest space his filled through valve o and also the other spaces h
which are in communication with the former through the passages 3.
At the same
time the liquid in the spaces g is impelled or forced through the passages b and the
valve q etc. etc.
Although the entrance and the outlet of liquid takes place through one valve only
for suction and another for delivery the two or three spaces for suction g or h distri-
buted round the axle, are filled simultaneously at each stroke and at the same time the
other two or three spaces of delivery or y filled with liquid at the commencement of
the stroke, are emptied. The construction of the improved pamp will be readily seen
from the drawings.

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 declare that what I
clnim is.
1. In a wing pump, the pump chamber divided in two or three spaces through two
or three fixed livisions having two valves for suction n and o and two others for
delivery, p and q in combination with two or three wings m fixed in the axle of the
り
pump and adapteil to be moved backwards and forwards in said clambers whereby are
constituted two or three spaces for suction and two or three spaces for delivery alter-
nating continually said suction spaces being in communication with each other
and said delivery spaces also in communication through respective passages through
the centre of the wings or in the casing of the pump or in both.
2. The combination in a wing pump of two or three spaces for suction communi-
cating with each other through passages and other two or three spaces for delivery also
in communication through passages said suction and dulivory spaces alternating
continually.
