IMPROVEMENTS IN PUMPS
Year: 1884

page_text: I, GERARD WENZESLAUS VON NAWROCKI of 124 Leipzigerstrasse Berlin in the
Kingdom of Prussia Germany do hereby declare the nature of said invention for
"IMPROVEMENTS IN PUMPS" (A communication to me from abroad by John Adrian
Jacobsen of Hamburg Germany) to be as follows:--
This invention relates to Improvements in the construction of pumps which aro
applicable as ships pumps mining pumps and in short all kinds of pumps. They
are particularly distinguished by simplicity of construction, strength, and easy
working.
The pump consists of the short or barrel body provided with the outlet spout,
bottom suction valve and delivery valve which has its seating in the hollow
plunger bucket. The bucket works up and down in the barrel or body of the
pump and is provided on the inner side with two pegs or projecting pieces lying
opposite to each other by which the bucket is hung on to a fork link which again
is hung on to a hook of the arm of a lever. As the lever with its hook goes
through a slit of the fork the lower hooks of this fork in which the pegs hang
strike against the guiding seat stem of the bucket valve, by which is attained that
the bucket must follow the lever arm in the downward stroke.
The lever arm has a ball projection or pivot which rests in an upper gutter
shaped part of the barrel. The lever arm is actuated by a handle inserted in a
socket formed on the lever and thereby the bucket is moved up and down. A
projecting piece on the lever limits the length of the upstroke of the bucket. The
gutter in which the ball pivot rests is continued all round the cylinder of the pump
so that the bucket, the lever and the fork link all can be turned round and the
pump thus be worked at any point.
To adapt the pump to work as a force pump the barrel has two suction valves
of which the one serves to suck up the water from underneath and the other from
the side.
The bucket is provided with guide ribs between which the bucket valve is
guided by corresponding lugs formed thereon. The lift of this valve is regulated
by set screws in the lugs on the bucket,

page_text: The lever connected to the fork is situated in an adjustable bearing piece and
attached thereto by a pin. The adjustable bearing piece is clamped on to a circular
beading formed round the top of the pump barrel by a set screw and clamping
piece. In this case also, as before the pump may be driven from any side, as the
bearing piece may be clamped on to any part of the circular beading.
The space under the bucket is connected to the air vessel so that when the
bucket valve is screwed fast on to its seating by the aforesaid screws which pass
through the lugs on the interior of the hollow plunger the pump may be used
as a force pump.. Or the hollow bucket may be ring like and closed all round and
with a central plunger open at top. The bucket valve is in the under side of the
bucket ring and in the upper side an exit pipe is arranged. In the under part of
the body of the pump are placed the two suction valves in the same manner and
for the same purpose as in the last described modification.
The middle part of the bucket is connected to the lever arm by a fork bolt and
connecting link or rod and as in the last arrangement clamped to the pump body.
The arrangement is such that either the inner cylinder works as bucket or it is
coupled with the outer ring-formed-one when both work together. In every case
the water drawn in by one of the suction valves goes through the bucket valve
and through the outlet pipe.

I GERARD WENZESLAUS VON NAWROCKI of 124 Leipzigerstrasse Berlin in the
Kingdom of Prussia Germany. do hereby declare the nature of said Invention
for "IMPROVEMENTS IN PUMPS (a communication to me from abroad by John
Adrian Jacobsen of Hamburg Germany) 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 improvements in the construction of pumps, which are
applicable as ships pumps mining pumps and in short all kinds of pumps.
They are particularly distinguished by simplicity of construction strength and
easy working.
The pump shown in vertical section at Figure 1 of the accompanying drawings
consists of the short or barrel body A, provided with the outlet spout F, bottom
suction valve C and delivery valve C¹ which has its seating in the hollow plunger
bucket P. The bucket P works up and down in the barrel or body A of the pump
and is provided on the inner side with two pegs or projecting pieces O lying
opposite to each other by which the bucket is hung on to a fork link N which
again is hung on to the hook M' of the arm of the lever I. As the lever I with its
hook M goes through a slit of the fork N the lower hooks N₁ of this fork in
which the pegs O hang strike against the guiding seat stem of the bucket valve C¹
by which is attained that the bucket P. must follow the lever arm I in the
downward stroke.
.
The lever arm I has a ball projection or pivot H which rests in an upper gutter
shaped part G of the barrel A. The lever arm I is actuated by a handle L
inserted in a socket formed on the lever I and thereby the bucket is moved up and
down. The projecting piece J on the lever I limits the length of the upstroke of
the bucket P. The gutta G in which the ball pivot H rests, is continued all round
the cylinder of the pump so that the bucket P the lever I and the fork link N all
can be turned round and the pump thus be worked at any point.
Figure 2 of the accompanying drawings shows a pump constructed on this
principle which may work as a force pump. In this case the pump barrel has two
suction valves of which the one C serves to suck up the water from underneath and
the other D from the side.
The bucket H is provided with guide ribs Y between which the bucket valve I
is guided by corresponding lugs A¹ formed thereon. The lift of this valve I is
regulated by the set screws B in the lugs Z on the bucket H.
.
The lever O connected to the fork T is situated in the adjustable bearing piece K
and attached thereto by a pin N. The adjustable bearing piece K is clamped on
to the circular beading J formed round the top of the pump barrel A by the set
screw M and the clamping piece L. In this case also, as before the pump may be
driven from any side, as the bearing piece K may be clamped on to any part of the
circular beading.
The space
J under the bucket is connected to the air vessel Q by a pipe G so
that when the bucket valve I is screwed fast on to its seating by the aforesaid
screws B¹ which pass through the lugs on the interior of the hollow plunger the
pump may be used as a force pump.
Figure 3 shows a somewhat differently constructed force pump. In this case
the hollow bucket N may be ring like and closed all round and with a central
plunger S open at top. The bucket valve O is in the under side of the bucket

page_text: ring M and in the upper side an exit pipe P is arranged. In the under part of the
body of the pump A are placed the suction valves E and F in the same manner
and for the same purpose as in the last described modification shown in Figure 2.
The middle part S of the bucket is connected to the lever arm Y by the fork
bolt V and the connecting link or rod W and as in the last arrangement (Figure 2)
by means of the clamp K clamped to the pump body. The arrangement is such
that either the inner cylinder S works as bucket or it is coupled with the outer
ring-formed one when both work together. In every case the water drawn in by
one, of the suction valves E or F goes through the bucket valve O in the hollow
cylinder M and through the outlet pipe P.
.
Having now particularly described and ascertained the nature of said invention
and in what manner the same is to be performed I declare that what I claim as
the Invention communicated to me is :-
