PROVISIONAL SPECIFICATION.
Coin-freed Measuring Tap or Apparatus for Drawing Off a Given
Volume of Liquid after the Insertion of a Coin.
I, JULIUS KRAYN, Merchant, of Salierring, Cologne, Germany do hereby
declare the nature of my invention to be as follows:-
The invention relates to measuring taps or to apparatus for delivering a given
quantity of liquid after the insertion of a coin.
The apparatus is set in operation by inserting a coin into a funnel-shaped
opening, then turning a handle, which causes a pin to come into contact with the
said coin, thereby establishing a connection between the handle and the hollow plug
or core of the measuring tap, and then turning the said plug until certain openings
come into juxtaposition, so as to provide an outlet for the liquid from the cask
into the plug.
The apparatus chiefly comprises a cock or tap mounted horizontally on a base-
plate and provided with a hollow plug or core adapted to contain the required
quantity of liquid, the said tap and plug being provided with three openings,
namely one for admitting the liquid from the cock or other vessel, one for
discharging the contents of the tap into a pipe, and one for the admission of air; a
sleeve or key mounted on the projecting part or spindle of the plug, said key being
guided and supported in a bearing and provided with a handle; a funnel shaped
coin-receptacle mounted on the upper side of the said sleeve or key and provided
at the base with a pair of narrow slots through passes (under certain conditions) a
radial pin which is fixed in the spindle of the plug, and projects through a segmental
slot of the said sleeve.
If the key is turned on the spindle, after a coin has been inserted, the latter.
comes into contact with the radial piu and thereby turns the spindle and plug the
required distance, after which the coin drops out of the funnel, owing to the altered
position of the latter. The tap is now in such a position, as to admit liquid from
the cask. If now the key is turned back, another radial projection or pin of the
spindle which passes through a segmental slot of the sleeve, is turned by the sleeve,
and thereby the plug placed in such a position as to allow the liquid to flow from
the tap into the discharge pipe mentioned above.
The admission of liquid to the tap takes place through a radial enlargement on
the upper side of the cock or tap, which communicates directly with the cask or
other receptacle from which the liquid is to be drawn.

Coin-freed Measuring Tap or Apparatus for Drawing Off a Given
Volume of Liquid after the Insertion of a Coin.
I, JULIUS KRAYN, Merchant, of Salicrring, Cologne, Germany, do hereby
declare the nature of my invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to apparatus for delivering a given quantity of liquid, after
the insertion of a coin.
The apparatus is set in operation by inserting a coin into a funnel-shaped opening,
Pine Rd17

page_text: measuring tap, and then turning the said plug, until certain openings come into
juxtaposition, so as to provide an outlet for the liquid from the cask into the plug.
Subsequently the handle is turned back and thereby the liquid allowed to flow from
the plug into the discharge pipe.
In the following description reference will be made to the accompanying drawings,
of which-
Fig. 1 is a plan and
Fig. 2 a side elevation of a measuring tap embodying my invention.
Fig. 3 is a section along line a- of Fig. 1.
Fig. 4 a section along line y-y.
Fig. 5 a section along z-z.

Upon a base plate a having projections a' a' is mounted a tap casing / provided
with a hollow plug e adapted to contain the required quantity of liquid and secured
to the casing or body of the tap by a screw nut d.
The projecting part or spindle ca of the plug c is surrounded and held by a key
or sleeve e which has its bearing in a bracket f secured to or formed on the base
plate a. The spindle is capable of turning in the sleeve e (or the sleeve on the
spindle) within limits determined by the slot n through which passes a projection c
of e, and the pivotal motion of the sleeve towards the right by means of the
handle g is limited by the pins e and f
The interior e of the plug c communicates with the outside by three openings, c²
and and e, the first serving to admit the liquid into the plug, for the admission
of air, and for the discharge of liquid from the plug. The top of the casing b
has an annular extension h, which is put into communication with the cask or other
reservoir from which the liquid is to be drawn off, so that the liquid can be drawn
directly from the cask without requiring a special retailing vessel, and consequently
the transfer of liquid from one reservoir to another.
The radial extension contains an opening ', through which the liquid is
admitted from the cask or other reservoir to the interior of the plug, as soon as the
port 2 of the latter lies below the opening ', that is to say, as soon as the plug has
been turned the required distance. In this position of the plug, the two openings c³
and care closed.
The angular motion of the plug in the casing is limited by the pin and the
ends or faces of the recess i¹.
On the sleeve or key e is mounted a funnel shaped mouth piece t provided at its
lower end with a pair of slots o placed so that the pin / fixed to the spindle c³ may
pass freely from one end of the slot m to the other.
The apparatus works as follows;--

In the position of rest, the plug, and the key with handle occupy the position
represented by the drawing, so that the mouth piece t is placed at the top, the
opening is situated under 63, and the opening is in front of the tube r.
If now
a given coin is thrown into the mouth piece, and the handle g, together with key e
and mouth piece t, turned to the right, the coin comes into contact with the pin l.
Consequently, during the further turning of the handle, the coin, which abuts
against the wall of the mouthpiece, will carry the pin with it, and therefore also the
spindle, and the plug c made in one piece with the same. This turning of the
handle is continued, until the pin el abuts against the detent f¹, in which
position the coin drops out of the mouthpiece, because the latter is now directed
downward.
In this position the opening c corresponds with b', and the cavity contained in c
will be filled with liquid. To allow the escape of air, a small orifice is provided in
the plug c at a suitable part thereof.
If now the handle, together with key e is turned to the left, the projection co
(Fig. 4) will carry the plug with it, so that the latter returns into the position of
Fig. 3.
This turn to the left is limited by the pin i and groove i¹, because the pin i

page_text: will abut against one of the edges or faces of the slot. In this position, the
opening corresponds with c³ and the opening ef with the tube r, and the liquid is
allowed to flow off through the said tube.
If a person turns the handle y, without having previously thrown a coin into the
mouthpiece, the pin will move freely in the slot m, the spindle c and the plug c
remain in their position, and the retailing of liquid therefore impossible.
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 ;-
A coin-operated measuring tap or apparatus for drawing given quantities of
liquid direct from a cask or other reservoir, having the characteristic feature, that
the coin itself, after having been thrown into a mouthpiece t, serves to turn the plug
into the filling position, while the return motion of the plug, and thereby the
discharge of the liquid, is effected by means of a projection, substantially as
described.
