Improvements in or connected with Siphons for Filling Bottles
and the like.
I, Dr. JOSEF RAAB, of Ludwigshafen on the Rhine, in the Kingdom of Bavaria,
German Empire, Physician, 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 :-
My invention refers to siphons as used for drawing off liquors out of barrels or
casks into bottles and the like, and my improvements in such siphons relate to the
combination of the siphon-pipe proper with an air-exhauster, a valve, and a stopper,
the whole for the purpose of drawing the liquor into the siphon-pipe without
necessitating the use of the mouth, and further, for the purpose of filling any
number of bottles without causing the least loss of liquid when changing the
bottles.
In order to make my invention more clear, I refer to the accompanying drawing,
in which similar letters denote similar parts throughout the several views, and in
which:
Fig. 1 shows the whole arrangement of the siphon-pipe with its accessories, and
Fig. 24 and 2B show the valve attached to the delivery end of the siphon-pipe.
The siphon-pipe is composed of the rubber-hose a and the tin-tube b, both parts
being connected with each other as well as with the conical rubber-stopper_c.
Hose a hangs down into the barrel d, and is provided at its suction end, with the
tin-head e holding this part of the hose in vertical position. A short bent tube fis
inserted into the bung-hole of the barrel, and the hose is passed through this tube,
so that the inner cross-section is not diminished.
The tin-tube b has, at its under end, a casing g with a valve h, which latter may
be opened by a spindle i fixed to it, and which may be closed by its own weight as
well as by the pressure of the liquid contained within tube b. The connection of
the casing g with tube b on one side, and with the seat for valve on the other side,
is effected by screw-threads, so that all these parts may be taken as under for the
purpose of a thorough clearing.
The rubber-stopper c above-mentioned holds the tin-tube b, as well as a short
thin tube k, the latter being provided with a hollow india-rubber ball 7 serving as
air-exhauster. The air within the bottle m communicates with the outer air
through a holen provided in stopper c. The size of ball is such that its capacity
corresponds to that of the siphon-pipe a b.
When compressing ball 1, the air contained therein enters the bottle m through
tube k, and escapes then out of the bottle through the hole n of the stopper. When
now closing this hole by a finger, and relieving the rubber-ball from the pressure,
the ball, sucking air out of the bottle, and out of the siphon-pipe, slowly regains its
previous original shape, partly by its own elasticity, and partly by the pressure of
the air acting on the surface of the liquor, and the latter, in consequence, is pressed
as well as sucked into the siphon-pipe, and thus into the bottle.
The length of the tin-tube b, or that of the spindle i, is such, that valve h is kept
now, after
open by said spindle as long as tube b remains within the bottle. If,
the bottle has been completely filled, the stopper is raised together with tube b, the
valve falls down on its seat, thus closing the delivery-end of the siphon-pipe, and
preventing any further efflux of the liquor. Bottle and siphon-pipe remain filled
with liquor, and the latter will begin to flow out again as soon as tube bis suffi-
ciently inserted into another empty bottle, so that valve h is lifted by the influence
of the bottom of the bottle on spindle i.
It will be seen from the foregoing, that the rubber-ball need be actuated only

page_text: at the commencement of work, and that any number of bottles may be filled
without letting the siphon-pipe become empty of liquid. In spite of this latter,
there is not the slightest loss of liquid, as the delivery-end of the siphon-pipe is
automatically closed long before it leaves the mouth of the bottle.
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. In a siphon, the combination with the siphon-pipe proper, of an air-exhauster,
adapted to rarefy the air within said pipe, the latter having a valve with a
protruding spindle attached to its delivery-end, for the purpose as described.
2. In a siphon, the combination with the siphon-pipe proper a b, having a valve h
with a protruding spindle i attached to its delivery-end, of a hollow india-rubber-
ball attached to a pipe k, the pipes k and being held together by a stopper c, for
the purpose as described.
3. In a siphon, the combination with the tin-tube and the rubber-hose a con-
stituting the siphon-pipe, of a metal-head e attached to the suction-end of bose a, of
a bent tube f, supporting the bent part of the hose, and of the valve h with its
protruding spindle i attached to the delivery-end of tube b, the latter tube as well
as a tube k with a hollow india-rubber ball being held together by a stopper c
adapted to fasten the whole device to the mouth of a bottle, for the purpose as
described.
