Improvements in and connected with Coin-freed Mechanisms.
I, MAX SIELAFF, of 23, Spener Strasse, of Berlin, in the Kingdom of Prussia,
German Empire, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in coin-freed mechanisms and has for
its object to provide means for opening the receiver when the mechanisms are
not in position for use, so that in consequence all coins inserted are conducted to
the outside again.
With coin freed mechanisms hitherto employed the driving mechanism often
was injured by coins inserted into the apparatus whilst the particular parts were
not in the right position for taking up the coins or were not in the position to
be coupled by the coins.
By the mechanism forming the subject matter of the present application coins
are prevented to be inserted into the apparatus when the different parts are not
in right position. The particular construction for attaining this end consists of
a coin receiver having two parts elastically connected together, one of which by
means of a crank lever can be removed from the other, whereby this crank lever
at its free extremity is of a form, that not only the rotating slide usually
employed, but also the driving mechanism can effect its displacement as soon as
the latter leaves the position for taking up the coins.
My invention will be better understood with reference to the accompanying
drawing, in which:
Figures 1 and 2 represent lateral views of my apparatus, and
Figure 3 illustrates detail views of the rotating slide and of the driving disc.
In the drawing a coin-freed mechanism for distributing liquids is represented
as an example. The apparatus essentially consists of a cock a, the plug of which
is moved by the rotating driving disc b. The movement is imparted to the
disc b in known manner from the exterior by means of a slide c coupled with
the disc b during a part of the rotating movement when a coin has fallen into
one of the slots d of the disc b.
Above the driving-disc b is arranged in suitable manner a coin receiver
consisting of two parts f and 9: both parts f g are connected together by a
turning joint h. The part f is fixed, whilst the second part can be laid round
In reposing position both parts are kept close to another by means of a spiral
spring i nderneath the coin receiver there is arranged a funnel discharging
all coins falling out of the coin receiver. When the coin regularly has passed
the receiver, it enters a coin channel 7 and is conducted to the driving disc b.
A double lever m at n is rotatably fixed to the casing e.
The form of this crank lever m clearly can be seen from Figures 1 & 2.
The upper part abuts against the movable part of the receiver. The lower
extremity is provided with two projections o¹ 02, the lower one of which extends
nto the path of the circular slide c, whilst the upper projection o¹ abuts against

with a number of depressions p corresponding to the number of the slots.
position of the parts is arranged in such a manner, that the lever m or more
precisely its projections o¹ only then extend into one of the recesses p of the
driving disc, when the latter is in position to take up a coin. As soon as the
disc is removed from this position, the projection o¹ of the lever m advances and
lies upon the cylindrical part of the mantle of the disc, thereby the lever being
displaced, the coin receiver opened and no coins being allowed to enter the coin-
channel and consequently to enter the apparatus.
My improved arrangement is of great advantage for coin-freed mechanisms
selling liquids for the reason, that the liquid trickles down already when the
cock only is opened a little, without the whole movement being possible to be
executed. Furthermore in this position no further coins could be inserted and
the apparatus cannot be used before the driving disc is adjusted in position.
When now such an apparatus does not work exactly, my improved arrangement
prevents with certitude the insertion of coins, so that no buyer can be robbed
of his coin. All coins, being inserted when the apparatus is in inexact position,
are removed to the outside through the funnel k.

Improvements in and connected with Coin-freed Mechanisms.
I, MAX SIELAFF, of 23, Spener Strasse, of Berlin, in the Kingdom of Prussia,
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:-
In automatic selling machines as heretofore made the impelling device could
easily get out of order because it was hardly possible to prevent the entry of a
coin into the apparatus while the several parts of same were not in the proper
position for receiving the coin or for causing the latter to form the connection
between them. By the device forming the object of the present invention the
entry of a coin into the coin receptacle of the apparatus is absolutely prevented
if the parts are in the wrong position. For this purpose the coin tester is so
connected with the actuating device itself, that the former can only be in the
normal condition suitable for receiving the coin when the parts of the actuating
device are in the proper position, and that in every other position of the parts
the coin tester is compelled to be in such a condition, that the coin, when put
into the slot of the apparatus, is obliged to be discharged therefrom again.
The coin tester consists of two parts hinged together one of which can be
opened or splayed from the other by means of one end of a double armed lever
the other end of which is so formed that it will be swung out not only by the
driving rotary disc but also by the actuating device as soon as the latter leaves
the position proper for the coin to form the connection.
One form of the apparatus is illustrated on the drawing filed with the
Provisional Specifications, and the drawing filed with the Complete Specification,
in which:
Figure 1 and 2 are two side elevations at right angles to each other, and

page_text: Figure 3 is a detail in plan,-Fig. 4 is a plan view similar to Fig. 3, showing
a modification of the slide,-Fig. 5 is a view similar to Fig. 3, showing the
driving disc having angular recesses instead of rounded ones.
The example shows an automatic apparatus for selling liquids consisting
chiefly of a cock a the plug of which is moved by a horizontally rotating driving
disc b. The movement of the disc b is effected from the exterior by means of a
rotary disc c which is influenced by a spring tending always to bring it back
into its initial position which by means of the coin falling into one of the slots d
of the disc becomes connected to the latter during part of a rotation. f g is a
coin tester arranged over the disc b and attached to the wall e of the machine
casing. The two parts f and are connected by a hinge h. The part f is fixed
while the part g can swing out or be splayed. In the position of rest the parts
are held together by a helical spring i. k is a shoot below the coin tester for

properly passed through the coin tester is guided through the coin gutter / to
the disc b. m is a double armed lever pivoted to the walle of the machine casing.
Figures 1 and 2 show its form. Its upper cranked end bears on the movable
part 9 of the coin tester. Its lower end is provided with two lugs o¹ and o³, the
latter to engage with the disc c and the former with the disc b, which as shown
of the same
in Figure 3 is mainly cylindrical but provided with notches
number as that of the slots d.
P
The position of the parts is such that the lug o¹ of the lever m is only in a
notch of the disc when the latter is in the right position for receiving a
coin. As soon as it is turned out of that position the lug o¹ comes against the
cylindrical part of the disc b, and the lever m will then be splayed open so that
no coin can then enter the coin gutter / or get into the driving mechanism of
the machine.
The splaying of the coin tester is especially of importance in the case of
machines for selling liquids because the liquid runs out of the cock even when
the latter is only opened a very little and consequently before the parts of the
mechanism have been brought into the right position for receiving the coin.
And when the cock has been cleaned at any time it is also quite possible that
the disc might by carelessness be left in a wrong position.
When therefore from such a cause the apparatus gets out of order, the afore-
said arrangement prevents absolutely the buver from losing his money by the
latter entering the machine proper because all coins entering a machine that is
out of order will be thrown out again by the shoot k.
The same result might of course be obtained by means of a plate or slide
arranged in the interior of the apparatus for closing the coin slot by covering it.
In the above described arrangement the disc c will only permit the coin tester
to assume its final condition or form, when the said disc is in its initial position.
that is to say, when the lug can engage into the cut out portion of the disc c
and the lug o into a notch p of the disc b (as shown in Figure 3). As soon as
the disc cand disc bare turned to any extent, the coin tester is under all
circumstances splayed open by means of the double armed lever m. because the
lug o will come onto the cylindrical circumference of the disc b and the lug 2

disc will again come into a position suitable for receiving a coin, that is to sav.
another notch p corresponding to the respective slot d will be in front of the
lug o. But it is nevertheless impossible for a coin to enter said slot & because
the disc still holds the coin tester in the splayed position, owing to the fact
Only
that the lug o lies still upon the cylindrical circumference of the disc c.
after the disc c has been turned back into its initial position would the arm m
be allowed to swing back. But instead of turning the disc into its first
position it is advantageous on that place of the circumference of this disc r.
which now lies in front of the lug 08 to provide a notch pl as shown in Figure 4.
Owing to this the lug o¹ will be able to enter the respective notch p and the

page_text: lug the notch p', so that the arm will be able to swing out far enough to close
the coin tester.
By the use of this last named arrangement a further advantage is obtained as
the use of a stop device or pawl is obviated against accidentally turning the
disc c too far or against the effect of centrifugal force. After the turning of 90°
the lug o' on the lever m drops into a notch p of the disc b and prevents a turning
too far.
A further security may be afforded by making the notches p and the lug
sharp cornered as shown by Fig. 5.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. In automatic selling machines, a device for ensuring that the inserted coin
shall be caused to be ejected from the machine by the coin tester in case the
working parts of the mechanism are not in the right position for the coin to
make the connection between said parts, said device being characterised by a
double-armed lever m for splaying the coin tester f g, said lever being caused
to swing out by the disc c as well as by the disc b the circumference of which is
so curved that it does not influence the lever when, and only when, in position
for receiving a coin, substantially as described.
2. A device as claimed under Claim 1, in which the disc c has a curved notch,
which when the disc b has been quite turned for delivery of the article of sale,
admits of the lever m going back into the position of rest thereby folding up the
coin tester to its normal condition, while at the same time by the entry of the
lever lug o¹ into one of the notches p of the disc b the latter is prevented from
accidentally being flung further round, substantially as described.
