PROVISIONAL SPECIFICATION.
Improvements in Syphons.
I, MARCELL RÜCKER of 14 Kandlgasse Vienna VII. in the Empire of Austria
Pharmacist do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a syphon which may be charged and
set in action without applying the mouth of the operator to the same to draw out
the air.
The improved syphon is constructed in two parts, the longer arm as it is termed
being closed with a cock below and terminating above in an enlarged chamber into
which the end of the shorter arm projects through a suitable air tight stopper or
equivalent. When the syphon is placed in position with the end of the shorter arm
immersed in the liquid to be drawn off, the air may be drawn out from this enlarged
chamber, while the cock aforesaid is closed, and this action will charge the syphon
before all the air has been exhausted. To draw out the air various means may be
employed such as a suction compressible ball with anti return valves, or the shorter
arm may be movable longitudinally into the longer arm, its air tight stoppor
forming a piston in the chamber. It may be moved by hand or through a rack and
pinion. The two tubes may also be connected one to the other by an elastic
diaphragm so that thrusting the one tube into the other the air is compressed and
partially expelled and on drawing the one tube out from the other the air is rarefied
sufficiently to draw up the liquid to charge the syphon.

COMPLETE SPECIFICATION.
Improvements in Syphons.
I MARCELL RÜCKER of 14 Kandlgasse Vienna VII. in the Empire of Austria
Pharmacist do hereby declare the nature of this invention and in which manner
the same is to be performed to be particularly described and ascertained in and
by the following statement :-
The object of this invention is to provide a syphon, which may be charged and
set in action without applying the mouth of the operator to the same to draw out
the air.
The improved syphon is constructed in two parts, the longer arm as it is termed
being closed with a cock below and terminating above in an enlarged chamber into
which the end of the shorter arm projects through a suitable air tight stopper or
equivalent. When the syphon is placed in position with the end of the shorter arm
immersed in the liquid to be drawn off, the air may be drawn out from this enlarged
chamber, while the cock aforesaid is closed and this action will charge the syphon
before all the air has been exhausted. To draw out the air various means may be
employed such as a suction compressible ball with anti-return valves, or the shorter
arm may be movable longitudinally into and from the longer arm its air tight
stopper forming a piston in the chamber. It may be moved by hand or through a
rack and pinion. The two tubes may also be connected one to the other by an
elastic diaphragm so that thrusting the one tube into the other the air is compressed
and partially expelled and ou drawing the one tube out from the other the air is
rarefied sufficiently to draw up the liquid to charge the syphon.

page_text: Syphons made as above described are shown in the annexed drawings which will
sufficiently indicate the construction by which the invention may be performed.
Fig. 1 shows a syphon with long leg A and short leg C, a is a cock in the long
leg, B is the enlarged chamber which is closed by cap D. F is the tube from the
compressible ball & with its valves fand g.
Fig. 2 shows this syphon charged ready for action.
Fig. 3 shows that form of syphon in which, the short leg C carries a plug h
forming a piston in the cylinder H which is prolonged above the enlarged
chamber B. K is a rack with which the pinion k meshes, k' being a handle for
revolving the pinion.
Fig. 4 shows this syphon charged and ready for action on turning the cock a.
Fig. 5 shows that form of syphon in which a diaphragm L of rubber sheeting or
any suitable air proof flexible material connects the legs C and A. as described.
Fig. 6 shows this syphon charged.
It will be understood that the size of the chamber B and of the cylinder H or of
the space enclosed by the diaphragm I when extended (Fig. 6) is so large, or so
large in reference to the space inclosed in the positions Figs. 3 and 5, that the act
of drawing up the branch c of the leg C will draw the air out of the legs A and C
sufficiently to charge the syphon.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is ;-
A syphon having in its longer leg a cock a and an enlarged chamber B into which
the end c of the shorter leg C projects, and means for exhausting the air from said
enlarged chamber by movement of the shorter leg or otherwise, substantially as
herein described.
