An Improved Syphon Head.
I, JOHANN MACEK, of 36 Josef Ring, Budapest, in the Kingdom of Hungary,
Chemist, 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 :-
The subject of this invention is a syphon head which is of very simple construction,
which acts with certainty and which requires only about one third of the material
required in the manufacture of other syphon heads.
In order that my invention may be the better understood, I now proceed to
describe the same, reference being had to the accompanying drawings and to the
letters and figures marked thereon.
Figure 1 is a side elevation of this syphon head ready for use.
Figure 2 is a vertical section thereof.
Figure 3 is a vertical section through the body of the syphon head, on line -
of Figure 1.
.
Figure 3 is a modification of Figure 3.
Figure 4 is a plan of the syphon head seen from below when unscrewed from the
bottle.
Figure 5 is a horizontal section on the line y-y of Figure 2.
Figure 5 is a modification of Figure 5.
Figure 6 shows a method of constructing the valve plug or stopper.
Figure 7 is a modification of Figure 2.
Figure 8 is a special form of construction of the syphon head shown in vertical
section when taken off the bottle and
Figures 9 and 10 are a side elevation and plan respectively of a detail.
A
The syphon head is of low bell shape. Its upper part carries a ring a¹, which
gives a pleasing appearance to the device and serves for carrying the bottle, thus
avoiding the bending and breaking of the handle. The interior of the lower part
of the syphon head is screw-threaded and screwed over the boss b, shown separately
in Figures 9 and 10. The boss is preferably cast with a slot 61, extending over
its whole length to facilitate the placing of the boss b on the next of the bottle.
recess a³, Fig. 3, is provided in the interior of the body of the syphon head, into
which is inserted the flanged projection d of the syphon tube c. A packing
disc e is placed on the neck of the bottle so that a tight joint is made (when the
syphon head is screwed on) between the projection d and the syphon body a on the
one hand, and the neck of the bottle on the other hand.
A recess Fig. 3 is arranged in the body of the syphon head, above the recess a²
which serves as a valve chamber, and in which is situated the horizontally moving
valve plug or stopper as well as the exit tube which is closed by the plug. The
valve as shown in Figures 1 to 5 consists of a stopper 9 of india rubber, carried in
the piece h into which is screwed the screw i which passes through the wall of the
syphon body. The screw i passes through a sleeve k of india-rubber which
surrounds also the piece h and completely fills the rear part of the valve chamber.
The elastic force of the sleeve k presses the stopper g, the piece h and the screw i
against the exit and serves also to make tight the opening 1, Fig. 3, in the body of
the syphon head through which the screw i passes.
The valve is actuated by a thumb lever m pivotted at m', the lip 7 of which
engages behind the head of the screw i, so that the screw head and therefore the
valve stopper 9 retire from the exit when the lever m is depressed, in order to

page_text: allow of the liquid contained in the bottle under pressure to pass through the tube c
into the exit pipe.
The part of the syphon head shown in Figure 34 is a modification of the form of
construction shown in Figure 3. In this case the valve chambers f¹ is arched,
while in Figure 3 it is rectangular. The form of construction shown in Figure 5*
differs only from that shown in Figure 5 by the section of the valve chamber, which
is round in Figure 54, while it is rectangular in Figure 5. The construction of the
valve, its action and mode of operation remain the same.
Figure 6 shows a modified form of construction of the stopper. In this case the.
stopper g and the ring or sleeve k are cast in one piece around the core h¹.
In the modification shown in Figure 7 a spiral springs is used instead of the
india rubber sleeve k. This spring s is placed over the screw i, and presses on the
one side against the inner flange of an india rubber ring o and the piece /, thus
preventing the liquid from coming into contact with the spiral spring.
previously
A slot is provided in the screw i, instead of the screw head
described, in which engages the lip of the thumb lever m to operate the valve
stopper.
Figure 8 shows a modification in which the action of the india rubber sleeve k
is supported by a spiral spring s¹ let into the syphon head.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1st. A syphon head consisting of a valve chamber with which communicates the
exit pipe closed by the valve stopper 9 which moves horizontally, and is pressed
against the exit by means of an india rubber sleeve k, or a spring s, and by which
the opening for the valve spindle or screw i is made tight.
2nd. A form of construction of the syphon head in which the horizontal valve
stopper is pressed against the exit pipe by an india rubber sleeve k, or a spiral
springs, Figure 7, enclosed on all sides with india rubber, whereby the passage for
the valve spindle or screw i is also made tight.
3rd. A form of construction of the syphon head claimed in Claim in which a
ring a' is cast to the body of the syphon head in order to avoid the use of the
lever m (designed for the operation of the valve) for carrying the bottle.
4th. For the purpose of attaching the syphon head (claimed in Claim 1) to the
bottle, a boss b, slotted longitudinally on one side in order to allow of the boss
being pushed over the bottle.
Dated this 3rd day of November 1894.
