Improvements in Syphons.
I. BERNHARD GREVE, Manufacturer, of Salierring Cologne, Germany, 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:-
In order to employ the syphons hitherto in use for drawing off liquids, an
oxhausting action has to be applied to one of the legs, after the other has been
inserted into the liquid which is to be drawn off. This result could be attained
in a variety of ways, but all the devices hitherto employed suffered from the defect,
that the second leg of the syphon had to be provided with an apparatus, which
rendered it in many instances difficult to apply the syphon.
These defects and the complicated nature of this class of syphons are probably
the reasons that have prevented the more general use of syphons for practical
purposes.
The novelty of the syphon forming the subject of the present invention consists
essentially in an arrangement, by which the necessary suction or exhausting action
originates at the top of the syphon, so that the legs of the syphon may be made
perfectly smooth and capable of insertion into the smallest casks or vessels. An
additional advantage of this syphon consists in the fact of its being composed of
adjustable legs and a vessel which forms the apex or top, so that the syphon can
be easily decomposed into its component parts, to facilitate cleaning and transport.
The legs, which are quite smooth, may be exchanged at will, and by means of
ball and socket joints, they can be made to assume any required position.
In the accompanying drawing Fig. 1 is an elovation and Fig. 2 a section of a
syphon embodying this invention.
Fig. 3 shows a ball-and-socket joint, with which the logs may be provided.
The syphon chiefly comprises two legs a b and the vessel_c.
The two legs or
tubes a and b, of which the one through which the liquid flows out is provided
with cock 6, do not form, as has hitherto been usual, a continuous or uniform
pipe, but are connected with one another by means of the vessel c.
This vessel or chamber c forms the top of the syphon, and the legs of the latter
are screwed into the bottom of the vessel c in such a way, as to form an air-tight
joint, for which purpose the bottom is provided with the two projections e.
The legs may form any angle with one another, the projections e, or the openings for
them, may he attached to, or formed in, the bottom correspondingly. The legs may
be likewise of any convenient length and shape. In order to be able to employ the
syphon in any position and to turn the legs in any desired direction, the bottom of
the vessel is preferably connected with the legs a and b by means of a ball and
socket joint g (Fig. 5). A piston c fits inside the vessel c and is provided with a rod e
and a handle h, so that it can be moved up and down inside the vessel. To prevent
the piston from being drawn out altogether from the receiver c, the latter has a cover d,
in which are a number of openings or holes o and which is secured by a bayonet joint.
Liquids are drawn off by this syphon as follows:-The piston is pressed, to the
bottom of the vessel c, the cock is closed and the leg a inserted into the liquid;
the piston e' is then raised, whereupon the liquid in the leg a flows up and fills both
the vessel c and the leg b. If now the cock be opened, the liquid proceeds to
flow out.
When sufficient fluid has been drawn off, the cock is shut. When the cock is
open, the syphon re-commences to act. If, however, sufficient liquid has been drawn
off, the piston is pushed down again and thereby the liquid expelled from the legs a
and b, the communication between the legs interrupted, and the customary tedious
draining-out avoided.

page_text: If it be desired, to employ the syphon for drawing off liquids from bottles, a cork
or plug, which fits the neek of the hottlo, is applied to the end of the log a; by this
means also the syphon is kept in position. The cork must, of course, be furnished
with an opening to admit the air.
Having now particularly describe and ascertained the nature of my said invon-
tion and in what manner the same is to he performed 1 declare that I claim :—
1. A syphon comprising in its construction a suction device situated at the apex,
and a pair of detachable legs or shanks, substantially as described.
2. The combination of a hermetically closed suction cylinder or vessol e forming
the apex of the syphon and containing a movable piston with a pair of syphon tubes
or legs a and b connected with the said vessel by ball and socket joints, one of the
said tubes being provided with a stop-cock, substantially as described and for the
purposes specified.
