Delivery of Liquids in Exchange therefor.
We, FRIEDRICH SCHILLING, and JOHANN GEORG ADOLF BRUNING, of the firm of
Schilling & Bruning, Merchants of Bremen, and HEINRICH STOLLWERCK, of Cologne
on the Rhine, Manufacturer to the Court, both in the Empire of 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
-
Our invention relates to an improved apparatus which is intended to deliver a
certain quantity of liquid after a coin has been introduced into the said apparatus.
In the accompanying drawings
Figure 1 is a sectional view of our improved apparatus.
Figure 2 is an elevation, the same at right angles to Figure 1.
Figure 2 is a detail of Figure 2.
Figure 3 is a sectional view of a modification of the improved apparatus.
Figures 4 to 8 inclusive show details of construction.
Referring to figures 1 and 2 of the drawings, A is a receptacle and B a measure or
measuring compartment which like most of the actuating parts are shown as being
contained in a casing of the shape of a bottle. The receptacle A which is to contain
the liquid to be sold, communicates with the measuring compartment B through an
aperture 6 which is arranged to be closed by means of a valve a controlled by the
spiral spring a. The measure B is provided with an outlet e which is controlled by
a valve d lifted from its seat in an opposite direction to the movement of the valve
the valve rod d' of the said valve d forming a continuation of the rod a carrying the
valve.a.
u,
When the apparatus is in its normal position, the valve a will be open while the
outlet c of the measure B is closed by the valve d which is held upon its seat by a
spring d². It will be seen that by means of this arrangement a suitable mechanism
brought to act with downward pressure upon the rod a of the valve a would at the
same time both close the aperture 6 by means of the valve a and open the outlet c by
means of the valve d so that the liquid having entered from the receptacle A into the

page_text: measure B and filling the latter, would by the operation of the said mechanism be
allowed to escape therefrom through the outlet c and through a tape connected there-
with into a glass or other receptacle held under the said tape.
The said mechanism which is put into operation by the insertion of a coin in any
convenient and well known manner, consists of a lever fulcrumined at and carrying
the valve rod a' and the connecting rod g pivoted thereto the other end of which is
pivoted to a bell crank lever connected to the bent lever i whose peculiar shape is
best seen from figures 2 and 4 of the drawings and which is fulcrumed to the bottom
of the casing at figure 2 and provided with a slot or aperture 1.
K is an angular sliding bar the free end of which corresponds to the size of the
slot and is arranged at such a distance from the latter as to cause the coin which
is introduced between the lever i and the angular bar & to be held by the latter against
that part of the lever i having the slot as shown in the top view figure 6. The
angular sliding bark has an extension / surrounded by a spiral spring and provided
at its rear end with a projection acted upon by a cam m which is contained
within the dummy cock C and forms the lower part of the vertical pivot of tho
handle n.
If there is no coin between the lever i and the angular piece k, the outlet c cannot
be opened by moving the cam m of the dummy cock by means of its handlen, as in
this case the said cam, will push the piece k clear through the slot 1 of the lever i, as
shown in figure 5 of the drawings. The lever i and consequently the outlet c and its
intermediate connections will therefore, not be operated, but will remain in its normal
position.
If however, a coin is introduced between the lever and the angular piece k, as shown
in figure 6 and the handle a turned, the said piece k will press the said coin against the
surface of the lever i and turn the latter on its pivot By reason of the inclined
position which is thus given to the surface of the lever i, the angular piece & will now
be out of line with the slot and its free end commence to bear against the surface of
the lever i, as shown in figure 7, when the coin will be released and drop down into a
suitable receiver, not shown in the drawings. The pushing piece k now bearing against
the lever i will turn the latter so that the bell crank lever h will now be turned on its
fulcrum and will pull down the rod g which will operate the valve rod a¹ and thus
close the valve a and open the valve d against the tension of the spring d². The
contents of the measuring compartment B will then flow out through the pipe of the
tap e, as will be readily understood.
When the glass or other receptacle which is held under the said tape is filled
with the contents of the measure B and the latter emptied, the purchaser will take his
hand from the handle n of the dummy cock C whereupon the spiral spring and the
spiral spring a³ encircling the valve rod a¹ and arranged between the receptacle A and
the lever will cause the handle n and the angular piece k as well as the bell crank
lever hand the lever to move into their normal positions, while the spring & will
close the valve d and raise the valve rod a' now relieved of the pressure exerted upon
the same by the operation of the lever i.
The valve rod a' is made of the form of a tube which above the sleeve d³ is provided
with a vent or air-hole o figures I and 8 for the purpose of establishing a communi-
cation between the outside air and the interior of the measuring compartment and thus
to ensure the flowing out of the liquid from the latter.
Figure 3 shows a modification of the apparatus for automatically delivering samples
of liquids as hereinbefore described with reference to the accompanying drawings, the
said modified apparatus being intended for use with barrels, casks or receptacles of
larger dimensions. This apparatus is screwed by means of the threaded sleeve p, upon
the tap 9 of the barrel, cask, or the like, and the measure B may be of any convenient
size. The volume of the said measure may be regulated to any desired quantity by balls
of glass or the like placed in the said measure.
Instead of using the cam m we may operate the said angular piece k by means
of a button fastened upon the end of some suitable sliding bar as will be readily
understood.

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 :-
First. In an apparatus for automatically delivering prepaid liquids, the combina-
tion with the lever i provided with the aperture of the angular piece k moved by
means of a sliding bar combined with a dummy cock C having a cam m or with an
equivalent actuating device, so that when there is no coin between the angular piece k
and the lever i the said piece k will pass clear through the aperture of the lever i
while if a coin is inserted between the two it will bring the said slot out of line
with the piece k and cause the free end of the said piece k to come in contact with
the surface of the lever i and move the latter on its pivot while the coin drops
down into a receiver, substantially as and for the purpose specified.
Second. The valve rod a¹ having the vento and carrying the valve a controlling the
communication between the receptacle A and the measuring compartment B, and the
valve rod having the sleeve d³ and controlling the valve d for the outlet c of
the measure B, in combination with the spring and lever/actuated by means
of suitable mechanism rendered operative by the insertion of a coin, substantially as
and for the purposes specified.
