Figure 3 shows a detail.
Figure 4 shows an alternative construction.
Into the bottle neck A of the requisite width is inserted the stopper B above
described, the edge of which is provided with a washer a, and is firmly and
hermetically secured to the lip of the bottle mouth by means of any of the known
devices (not specially illustrated in the drawing).
The said stopper B, has as already stated a central aperture d, into which the
side bent channel C, discharges. There is also another narrow aperture d¹. The
openings of both these apertures are closed during the fermentation of the beer
by means of india-rubber or cork stoppers. The pressure tube D is fixed to the
tube C below; this tube terminates in a spherical piece provided with a side slot.c.
When the white beer has fermented sufficiently, the syphon proper or pouring
apparatus is fixed above upon the stopper B.
This apparatus consists essentially of the carbonic acid holder E, the cover E!
of which is held by means of the claws e pivotally attached to the stopper B,
whilst el is an air tight washer.
The tube F is, firmly soldered into the cover E¹ at the point f. This tube ends
beneath in a perforated hemispherical cap which stands exactly opposite the
opening of the tube C. Above the cover E¹, the said tube expands somewhat and
is there surrounded by the piece G, which piece engages with an inner sleeve g,
at F. The said piece G preferably of copper is widened below into a disc, with
its rim h projecting downwards. The said rim is guided at the side by means of
the cylindrical projection e², of the cover E', as well as in an annular slot e³. The

page_text: piece e³ is moreover provided with a screw-thread to engage with the wing-nut J,
against which piece the upper part of G is pressed by means of the spiral spring K,
which is placed upon the piece E', and lies in an annular slot K₁ formed in the
lower part of G around the tube F.
The tube F passes through the upper cylindrical part of G and has a side pro-
jection branch tube F¹ screwed into it. One fourth of the circumference of the
piece G being cut away at that point, also leaving a certain amount of free play
above the said projection F¹.
Below in the part E', and projecting into the carbonic acid holder E, is screwed
a valve cover L, shown on an enlarged scale in Figure 3, which valve cover
contains the valve L opening downwards and up-held by the spring. This valve
is prolonged above into a spindle and air-tight piston U. Passing through the
cover E', the said spindle ends above in a disc 2, which comes in contact with the
under side of G.
From the valve tube there passes at one side a tube M through the carbonic acid
holder E, and the opening into the bottle.
The apparatus operates as follows:-When the piece G at the head of the
apparatus is turned around the tube F, the hole g² comes to stand opposite the
inner aperture of F¹, and thus connection is established between the bottle A and
the tube F, by way of the tube D, the tube C, and the tube F and the hole g²;
by turning G the valve L is at the same time pressed down, because the lower
surface of G at the point opposite to the axis of the valve L is formed wedge
shaped. Consequently the carbonic acid contained under pressure in E can escape
through the valve L, and the tube M, and exert a pressure upon the contents of
the bottle so that the fluid flows out through the course already indicated; when
the piece G is turned the opposite way the simultaneous closing of the tube and
of the carbonic acid inlet valve is effected.
By means of this construction of the syphon-head and by means of the division
of the exit tube into the two parts 1) and F, the object of the invention set forth
at the commencement is attained so perfectly, that the beer after the piece B has
been placed upon the vessel can be left to ferment, and when the upper part is
attached no disturbance or agitation of the beer is caused as would inevitably be
the case if the tube 1) formed the direct continuation of F and had to be inserted
into the bottle from above.
The tube D is formed in the shape of a hemisphere below the slot c, in order
that any solid deposit carried into it can settle there.
The construction illustrated in Figure 4 differs from that already described, in
that above the carbonic acid holder E there is fixed by means of the wing-nut J,
a support G, which holds the cock F³, which is at its lower end fitted tightly into
the tube F and whose side opening f³, communicates when in the proper position
with the exit tube f, so that the fluid passes upwards through the tubes D, C,
and F and can run out. The supply of the carbonic acid out of the vessel E is in
this case effected by having a hollow space E3 formed between the part G¹ and the
carbonic acid chamber cover E³. A valve cover L' hanging below in the carbonic
acid holder is screwed into the bottom of E2, the valve L of which is usually held
upon its seating by the pressure of the carbonic acid but can be pressed down and
opened by means of a projection z in the form of a wedge attached to the said
cock F. As soon as this cock is opened, the carbonic acid will then flow through
the openings o, of the valve cover L', and through the upper space E³ above the
cover E and through the tube M into the vessel A.
There is moreover provided a safety valve P, an inlet Q for the carbonic acid,
which is closed by means of the back pressure valve q and the cap Q¹.
The new syphon-head has advantages over other bottle or jar syphons for
aerated beverages in that by means of a single syphon-head any desired number of
bottles may be successively tapped without disturbing the sediment and thus
injuring the quality of the contents,

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
d
1. A stopper for bottles or jars containing white beer or other like liquids,
having two axial apertures d and etc. capable of being closed during the fer-
mentation process by means of corks or the like, and of which apertures the
largest possesses a short tube F having a rounded perforated end, connecting to
an angular channel C, which channel communicates on the one side with the said
wide tube F, and on the other side with the tube D firmly fixed in the underside
of the stopper B, the said tube D passing downwards almost to the bottom of the
vessel A and terminating in a hemispherical piece provided with a slot c, whilst
the narrower tube d¹ connects with the carbonic acid tube M of a beer syphon-
head.
2. An improved syphon with carbonic acid charge especially adapted for the
delivery of white beer and the like from bottles or the like, provided with the
closing device set forth in Claim 1, characterized by the arrangement that upon
the operating of the syphon-head, a quantity of carbonic acid corresponding to the
outflow is simultaneously discharged into the bottle by means of the pressure
tube M connecting to valve L and passing through the carbonic acid holder E
placed upon the bottle A. A tube F provided above with a side exit pipe F¹,
bears a piece G surrounding the end of the tube F inside and outside; the sleeve
shaped part whereof fits inside in the tube and possesses a hole g² corresponding
to the aperture of the exit tube F¹; the said part G being revolubly attached
below to the carbonic acid holder cover E', whereby on the same being turned the
carbonic acid valve is opened by means of a wedge on its under surface, and at the
same time connection is established between the exit pipe F1 and the pressure
tube F, by means of the aperture g².
3. The modification of the improved syphon-head above set forth in which the
carbonic acid vessel cover is provided above with a cavity E³, and a cock, the
spigot of which is firmly fixed in the tube F is carried upwards above the cover E³
and possesses at its end a side projection z by means of which it can when in the
open position open a valve of the carbonic acid vessel so that the carbonic acid
can escape through the space E³ over the cover E³ to the tube M passing into the
beer bottle; substantially as described.
