COMPLETE SPECIFICATION.
An Improved Syphon Bottle for Retailing Beverages.
1, HERMANN PETER, of 43 Ritterstrasse, Berlin, in the German Empire,
Manufacturer, 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, reference being had to the accompanying drawings and
to the letters and figures marked thereon, that is to say :-
This invention relates to an improved syphon bottle for retailing small quantities
of beverages, such as beer, mineral waters, and the like by the use of carbonic acid
stored under pressure in a separate reservoir.
The characteristic features of the invention are: the arrangement for closing or
opening the valve for the carbonic acid gas by means of the draw off tap at the top
of the syphon, so that the gas under pressure causes the liquid in the bottle or
vessel to pass, with more or less force, up the draw off tube from the bottom of such
vessel and out at the tap; and the means for connecting the fittings to the neck of
the bottle or vessel, consisting in adjustable clamping devices for the purpose of
insuring, at all times, an airtight joint therewith.
And in order that the invention may be readily understood, I will describe the
same fully with reference to the accompanying drawings, in which:
Fig. 1 is an elevation of a syphon bottle constructed in accordance therewith.
Fig. 2 is a vertical section of the same.
Fig. 3 is a plan of the carbonic acid reservoir with the cover removed.
Fig. 4 is a detail view showing one of the clamping devices.
The
The syphon comprises a bottle or vessel A of glass, earthenware, or other suitable
material, in which is contained the beverage. B is the reservoir for the carbonic
acid; it is formed of two concentrically arranged cylinders closed at bottom by a
plate and at top by a cover s and containing the pressure-supplying means.
inner cylinder is of a diameter large enough to contain the draw off tube d and to
leave a free space around this tube for the passage of the carbonic acid from the
cover downward, so as to enable it to act on the liquid in the bottle or
vessel A.
The outer cylinder extends beyond the inner one and is screwthreaded at top to
receive a screw nut G, by means of which the draw-off tap H is connected air-tight
to the said cylinder.
The space con prised between the lower part of the tap H and the covers is
provided at one side with an outlet socket R fitted with a safety valve, and has a
gas regulating device in the interior for controlling the pressure on the liquid in
the bottle or vessel. Said covers is provided with a nipple g having a central
perforation leading into the carbonic acid reservoir, and this nipple is screw-
threaded to receive a short sleeve or ring provided with an indiarubber washer
adapted to close the gas outlet k by screwing down the ring l. To enable this to
be done, arrange a forked lever m m (Fig. 3) securely fastened to the ring 1,
and adapted to be operated in one or other direction by a short lever o mounted on
the draw off tube, and to act either on the one or the other arm of the forked
lever m.
When the arms m, m, of the forked lever are moved in one or other
direction the ing 1, with the rubber washer, will be screwed up or down on the
nipple g and thereby close or open the orifice k.

page_text: The plug h, of the draw-off tap, is rigidly connected with the upper end of the
draw-off tube d, and is provided with an outlet tube I, and with a handle K.
The gas reservoir B is formed with a flange E which serves as a cover to the bottle
or vessel, and a rubber washer D, between the neck of the vessel and the cover E,
enables a tight joint to be made by the aid of the clamping device F; said clamping
device being so adjusted as to always ensure a tight joint, notwithstanding any
inequality or difference in a new rubber washer D.
As shown at Fig. 4, the clamping device F consists of a bent wire f¹ fitted in
grooves on the extension w of the lange E of a crosshead f"; and of a screw
threaded hinged pin f adapted to be screwed into a tapped hole in the
crossbead The screwthreaded pin fis hinged by its enlarged part f* to
lugs on the ring V at the neck of the bottle. In order to adjust the clamping
device, it is only necessary to remove the wires f¹ from their seats w, and to then
screw them up, or down, on the pins f, as may be required, for tightening or for
lengthening the clamp.
Z is a handle by means of which the syphon may be carried from place to
place.
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. A syphon bottle for retailing beverages, having its pressure reducing valve
arranged in a chamber formed by the extended outer cylinder of the gas reservoir
and the shell of the draw-off tap, substantially as described.
2. In syphon bottles for retailing beverages, a carbonic acid gas reservoir
consisting of two concentric cylinders of unequal length closed at both ends and
adapted to form a passage, through the small cylinder, for the draw off tube
and for the gas down into the vessel containing the beverage, substantially as
described.
3. In syphon bottles for retailing beverages, the means for regulating the
admission and pressure of the gas in the vessel containing the beverage, substantially
as described.
4. In syphon bottles for retailing beverages, the means for opening or closing the
orifice of the nipple in connection with the gas reservoir, substantially as described
with reference to Figs. 2 and 3 of the drawings.
5. In syphon bottles for retailing beverages the clamping device, substantially as
described and shown with reference to Figs. 2 and 4 of the drawings.
6. My improved syphon bottle for retailing beverages, having its parts arranged
and combined to operate substantially as herein before described and as shown in
the annexed drawings.
