page_text: I, HEINRICH CHRISTIAN WINKEL, of Basmannia Street House Zarin Moscow, Russia,
Engineer, do hereby declare the nature of this invention to be as follows:-
Pumps according to this invention are primarily designed for use as artesian-well
pumps and pit-pumps and are characterized by the fact that a double delivering action
is produced by means of two co-axial pistons placed on a single rod.
Each piston forms with its respective cylinder a single-acting pump, and the rod
connecting the two pistons extends through a fixed partition-wall which shuts off the
upper pump-cylinder from the lower one. The lower piston delivers during its down-
ward stroke, and the connection with the upper part of the pump is effected either
by means of a hollow rod connecting the two pistons or by means of passages which
surround the lower pump-cylinder. The lower pump-piston may be constructed either
as a valve-piston or as a disc-piston, a suction-pipe with suction-valve being, in the
latter case, connected to the pump-cylinder.
In one arrangement of pump, according to this invention specially adapted for use
as an artesian-well pump, the upper pump-cylinder is closed at its bottom by a
partition-wall below which the lower pump-cylinder is arranged. The upper pump-
cylinder is connected directly with the rising or delivery pipe. The upper pump-
piston is connected with the lower pump-piston by means of a pipe which opens at its
lower end into the lower pump-cylinder (which is closed at the bottom) and is
provided below the upper piston with holes. Both the pistons are constructed as
valve-pistons, but the valves of the upper piston open upwards, whereas those of the
lower piston open downwards. In order to deliver, the pump must dip into the
liquid to be pumped, to such an extent that holes provided in the upper end of
the lower cylinder will be immersed.
When both pistons are moved downwards by means of the pump-rod, the valves of
the lower piston close, and the liquid in the lower cylinder is forced through the
connecting pipe and the open valves of the upper piston into the delivery-pipe.
Thus the lower part of the pump acts as a force-pump.
In the upward movement of the two pistons, the valves of the upper piston close,
and the upper part of the pump works with a forcing action, whilst liquid flows
through the open valves of the lower piston and the apertures of the lower cylinder,
into the last-mentioned cylinder, and passes into the upper cylinder through the
connecting pipe. To enable the two pistons to be removed from the pump, the
partition-wall is unscrewed. This effected by means of projections on the lower
surface of the upper piston, which correspond to projections on the upper surface of
the said wall the arrangement being such that when the two pistons are in their
lowest position, the partition-wall can be unscrewed by turning the pump-rod and
both pistons lifted out together with the partition-wall by means of the said pump-
rod. In a similar manner, after all the parts have been inserted into the pump-
cylinders, the partition-wall can be screwed in again by means of the upper piston.
In another pump according to this invention the lower piston is formed as a disc-
piston and to the lower pump-cylinder there is attached 'a.suction-pipe provided with

page_text: The
a suction-valve. The openings in the upper part of the lower pump cylinder serve in
this case simply for the inlet of air: In this modification the upper side of the
disc-piston is provided with projections for the purpose of enabling the partition-wall
to be unscrewed by means of projections on the under surface of the same.
valve seat of the suction-valve is provided with an upper bridge-piece having a
screw-pin adapted to fit a nut carried by the under part of the lower piston, so that
the valve-seat of the suction-valve can when required be unscrewed and taken out
also by means of the lower piston.
In a third pump, which is a modification of the first herein before described, the
connexion of the two pistons is effected by means of a solid rod. The lower pump-
cylinder is surrounded by a number of passages by means of which the lower part of
this pump-cylinder, which is closed at the bottom, is connected with the lower part
of the upper pump-cylinder. The partition-wall is in this case unscrewed by means
of a piece of square cross section on the rod that connects the pistons.
In another construction of pump according to this invention, consisting of a
modification of the pump secondly herein before described, the lower part of the lower
pump-cylinder is connected by passages surrounding the latter with the lower part of
the upper pump-cylinder and the two pistons are connected by a solid rod.
The last two pumps have the advantage over the ones first described that the
dimensions and proportions can be so selected that the upstroke and the downstroke
of the pistons will move forward equal quantities of liquid.
The two pumps first hereinbefore described have, however, the advantage that they
can be employed as artesian-well pumps or artificial springs.
If desired, the arrangement of the cylinders and pistons may be reversed, the
cylinder having the piston with downwardly opening valves being arranged above
the cylinder having the piston with upwardly opening valves. In a pump according
to this arrangement the two pistons are connected together by a solid rod, the suction-
pipe opens directly into the lower cylinder, and the upper part of the lower cylinder
is connected by passages with the upper part of the upper cylinder, the lower part of
which communicates directly with the delivery-pipe.

Improvements in Pumps.
I, HEINRICH CHRISTIAN WINKEL, of Basmannia Street, House Zanin, Moscow,
Russia, Engineer, 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 :-
Pumps according to this invention are primarily designed for use as artesian-well
pumps and pit-pumps and are characterized by the fact that a double delivering
action is produced by means of two co-axial pistons placed on a single rod.
Each piston works in its respective cylinder, and the rod connecting the two
pistons extends through a fixed partition-wall which closes the lower end of the upper
pump-cylinder. The lower piston delivers during its downward stroke, and the
connection with the upper part of the pump is effected either by means of a hollow
rod connecting the two pistons or by means of passages which surround the lower
pump-cylinder. The lower pump-piston may be constructed either as a valve-piston
or as a disc-piston, a suction-pipe with suction valve being in the latter case,
connected to the pump-cylinder.

page_text: Fig. 1 of the accompanying drawings illustrates in longitudinal section an
arrangement of pump, according to this invention specially adapted for use as an
artesian-well pump. In this case the upper pump-cylinder a is closed at its bottom
by a partition-wall 6 below which the lower pump-cylinder d is arranged. The
upper pump-cylinder a is connected directly with the delivery pipe f. The upper
pump-piston g is connected with the lower pump-piston h by means of a pipe i which
opens at its lower end into the lower pump-cylinder d (which is closed at the bottom)*
and is provided below the upper piston g with holes as shown. Both the
pistons g and h are constructed as valve-pistons, but the valves m of the upper piston
open upwards, whereas those n of the lower piston open downwards. In order to
deliver, the pump must dip into the liquid to be pumped, to such an extent
that the holes provided in the upper end of the lower cylinder d will be
immersed.
When both pistons are moved downwards by means of the pump-rod / the valves n
of the lower piston h close, and the liquid in the cylinder d is forced through the
connecting-pipe i and the open valves m of the upper piston into the delivery-
pipe f. Thus the lower part of the pump acts as a force-pump.
In the upward movement of the two pistons g and h the valves m of the upper
piston close, and the upper part of the pump works with a forcing action, whilst
liquid flows through the open valves n of the lower piston h and the apertures k of
the lower cylinder d, into the cylinder d, and passes into the upper cylinder through
the connecting pipe i. To enable the two pistons to be removed from the pump, the
partition-wall b is unscrewed. This is effected by means of projections o on the
lower surface of the upper piston g to which correspond projections on the upper
surface of the wall b the arrangement being such that when the two pistons are in
their lowest position, the partition-wall b can be unscrewed by turning the pump-
rod and both pistons lifted out together with the partition wall by means of the
said pump-rod. In a similar manner after all the parts have been inserted into
the pump-cylinders, the partition-wall b can be screwed in again by means of the
upper piston g.
Fig. 2 is a longitudinal section illustrating a modified construction in which the
lower piston his formed as a disc-piston and to the lower pump cylinder d there is
attached a suction pipe p provided with a suction valve s. The openingsk in the
upper part of the lower pump-cylinder & serve in this case simply for the inlet of
air. In this modification the upper side of the disc-piston h is provided with
projections o for the purpose of enabling the partition-wall 6 to be unscrewed by
means of projections on the under surface of the same. The valve-seat of the
suction-valves is provided with an upper bridge-piece having a screw-pin adapted to
fit an internally screw-threaded part carried by the under surface of the lower
piston h, so that the valve-seat of the suction-valve scan, when required, be unscrewed
and taken out also by means of the lower piston h.
Fig. 3 shows in longitudinal section a modification of the pump first herein before
described and Figs. 4 to 7 are sections according to the lines 1-1, 2-2, 3—3,
and 4-4 of Fig. 3. In this case the connexion of the two pistons g and h is
effected by means of a solid rod . The lower pump-cylinder d is surrounded by a
number of passages u, by means of which the lower part of this pump-cylinder d,
which is closed at the bottom, is connected with the lower part of the upper
pump-cylinder a. The partition-wall b is in this case unscrewed by means of a
piece o¹ of square cross section, which is provided on the rod ¹ and which fits into a
corresponding recess r in the wall b.
Figs. 8 to 10 inclusive shew another construction of pump according to this
invention, consisting of a modification of the pump shewn in Fig. 2. In this
arrangement the lower part of the lower pump-cylinder d is connected by passages u,
surrounding the latter, with the lower part of the upper pump-cylinder and the two
pistons g and h are connected by a solid rod ¿¹. This construction will be clear
without further description.
The last two modifications have the advantage over the ones first described that

page_text: the dimensions and proportions can be so selected that the upstroke and the
downstroke of the pistons will move forward equal quantities of liquid.
The two pumps shown in Figs. 1 and 2 have, however, the advantage that they
can be employed as artesian-well pumps or tube-well pumps.
If desired, the arrangement of the cylinders and pistons may be reversed, the
cylinder having the piston with downwardly opening valves being arranged above
the cylinder having the piston with upwardly opening valves.
As will be seen the
Fig. 11 illustrates a pump according to this arrangement.
two pistons g and h are connected together by a solid rod, the suction-pipe opens
directly into the lower cylinder a, and the upper part of the lower cylinder a is
connected by a number of passages u (by which the cylinder d is surrounded) with
the upper part of the upper cylinder d, the lower part of which communicates
directly with the delivery-pipe. The piston 7 in its upstroke forces liquid through
the passages u above the piston h which is then likewise moving upwards and allows
liquid to pass through its valves into the delivery-pipe.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. A deep-well pump in which there are two co-axial pistons, of which the
upper (g) is a valve piston and the lower (h) a valve-piston or a disc-piston, the
pistons being located respectively in upper and lower cylinders (a and d) that are
separated by a fixed partition-wall (b) and being placed on a single hollow or solid
rod (or) passing through the partition wall (b), and the arrangement being such
that on the entry of fluid at only one place (common to the two cylinders) of the
lower cylinder, the separate actions of the two pistons supplement each other in
such a manner that the lower piston (h) presses fluid during its downward
movement, through the hollow rod (2) or through the passages (u) surrounding
the lower pump-cylinder (d), under the upper piston (g), which is then likewise
moving downwards and allows fluid to pass through its valves (m) into the
delivery-pipe (f). .
2. The reverse arrangement of the deep-well pump in which the cylinder a with
piston is located below the cylinder d with piston h, the upper part of. the
cylinder a being connected by a number of passages, by which the cylinder & is
surrounded, with the upper part of the cylinder d.
3. Pumps constructed, arranged, and operating substantially as hereinbefore
described with reference to and respectively shown in Fig. 1, in Fig. 2, in Figs. 3 to
7 inclusive, in Figs. 8, 9, and '10, and in Fig. 11 of the drawings annexed.
