Improvements in Apparatus for Forcing, Compressing, and
Exhausting Fluids.
I, OSKAR DALISCH, of 10% Markt, Neisse, in the Kingdom of Prussia and
German Empire, Goldsmith, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to an apparatus which may be employed at will for forcing
compressing and exhausting fluids.
The construction of the apparatus is illustrated by the accompanying drawings to
which reference will hereinafter be made, and in which―
Figure 1 represents a side elevation ;
Figure 2 a vertical transverse section ;
Figure 3 an elevation of the centre of the apparatus ;
Figure 4 a vertical cross section of the hub; and
Figure 5 a cross section through the stationary centre.
The apparatus consists of two closed chambers arranged upon opposite diameters
of a hub which is capable of being rotated upon a stationary centre. Each chamber
has two ports communicating through the hub with the centre in which three
passages are formed. One of the ports opens direct into the bottom of the
chamber, but the other opens into a tube extending to the opposite end of the
chamber and terminating in an open end. One of the passages in the stationary
centre serves to put the open port of one chamber into communication with the
tube enclosed port of the other chamber when the two chambers are in the vertical
position, and the other two ports are respectively in communication with pipes
communicating with a three way cock which communicates through a third pipe
with the vessel containing the fluid to be operated on.
In the accompanying drawings, a and b, are the two opposed chambers which are
respectively screwed or secured upon bosses formed upon the hub bored to fit
upon the stationary centre c, which is preferably conical and is mounted upon the
supports A B carried on the foundation plate C. It is provided with three
passages d, e, v, of which corresponds with the openings or ports in the chambers
and de also correspond with the ports and communicate with the pipes d'e¹.
If the lower vessel a, Figure 1, is filled with water, or with other suitable liquid,
the vessel being empty, and the vessels are then turned over so that a occupies the
position before occupied by b, as shewn by Figure 2 the liquid will pass through
the port and the pipe n into the lower chamber, the air wherein will thus become
compressed. The three way cock with which the pipe d'e¹ communicates, is
turned to put the chamber 6 into communication through the port d pipe d¹ and
pipe f, with the vessel 9. The pressure created in the chamber b is thus trans-
mitted to the vessel g, and any fluid contained therein is thereby forced out through
the pipe k and the tap i.
When the supply of water in a is exhausted, the position of the vessels is
reversed and the operation will thus be repeated and can be repeated as often as
may be required. Each of the chambers may be provided with an air valve or it
may be arranged to introduce a fresh supply of air into the vessel through the
pipe d'or e which is not in communication with the lower vessel and through the
tube m, or n.
The passages d and e in the stationary centre are provided with ball valves e p to
prevent any fluid flowing in the wrong direction.
If the pipe be connected with the pipe e, by means of the three way cock . the

page_text: apparatus may be used for suction instead of for compression, by employing it in
precisely the same manner as before described.
Having now- particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
-claim is―
:
1. An apparatus for forcing compressing and exhausting fluids; constructed
arranged and operated substantially as hereinbefore described and as illustrated by
the accompanying drawings.
2. In an apparatus for compressing forcing and exhausting fluids, the combination
and arrangement on a stationary centre of two opposed chambers capable of rotation
thereon, and each provided with a tube open at one end to the chamber and at the
other to the centre and a port also communicating with the centre, a passage
through the centre adapted to put the tube of one chamber into communication
with the port of the other, and two additional valve controlled passages in the
centre connected by two pipes with a three way valve and communicating with the
port in one chamber and with the tube in the other, and a connecting pipe from
the three way tap, substantially as and for the purpose hereinbefore described and
as illustrated by the accompanying drawings.
3. In the apparatus of the type herein set forth for forcing compressing and
exhausting fluids, a stationary centre around which the apparatus is capable of
being rotated, and which is provided with passages, two of which are connected
with a three way cock and with ports in the apparatus, and one of which is
capable of putting the two sides of the apparatus into communication; constructed
substantially as hereinbefore described and as illustrated by the accompanying
-drawings.
