Improvements in and relating to Automatic Coin Freed Apparatus.
I, MAX HEYDER, of Saalfeld-on-the-Saale, in the Empire of Germany, Manu-
facturer, 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:-
My invention relates to automatic coin freed apparatus, and comprises a coin
shoot which is furnished with an electro-magnetic contact device or switch and
possesses the advantage that, while it can be made at a low cost, is sure in its
operation.
This coin shoot utilizes as much as practicable the electricity at disposal,
operates automatically and surely, occupies little space, cannot be tampered with,
and, by reason of its peculiar construction, can be easily applied to any kind of
automatic coin freed apparatus. Moreover, owing to the short time in which an
operation of the mechanism of this coin shoot takes place and to the small power
it requires, the cells are used very little, and will thus have a long life.
In the accompanying drawing my improved coin shoot is represented as used
for a small portable induction apparatus giving for say half a minute an electric
current which can be regulated at will. In this case the electricity is already at
disposal, as the cells arranged in the induction apparatus are required for
administering electric shocks, otherwise, for instance if the coin shoot is designed
to be employed for other automatic coin freed apparatus, it would be necessary
to provide a source of electricity.
For the sake of simplicity the cells and also the arrangements necessary for
administering the electricity are omitted from the drawing, only the clockwork
being indicated which serves to determine the time of flow of the current.
Figure 1 illustrates such clockwork operating in combination with my coin
shoot, the conductors indicated being connected with an electric battery (not
shown).
Figures 2 to 5 represent sections, taken on the line of Figure 1, of the
coin shoot, in which the path traversed by the coin is indicated so as to show the
different positions of the parts of the mechanism.
The coin shoot a, consisting of hard rubber or similar material, is arranged
between two plates 6 61, and has several levers set in operation by the coin for
actuating the automatic apparatus. A stop levere furnished with a nose c¹¹ and
having its fulcrum at c¹ is connected with the lever by an adjusting screw d¹.
The spring always tends to move the lever d back to its original position. I
provide a peculiarly shaped contact lever e which has its fulcrum at e¹. One
arm of this lever makes contact with the two-armed lever f, whilst the other
arm i reaches below the armature lever which in Figure 1 is prolonged to the
clockwork A. On the arm of the aforesaid lever is arranged a small insulating
plate ¹.
At the exit of the shoot g I arrange a contact-breaker h, which is
pushed backwards on the passage of the coin. The conductor 1 connects the
ever with the contact-breaker h which in its position of rest bears against the
The conductor 3 extending from the screw 4, and the conductor 5
crew 2.

page_text: extending from the fulcrum e¹ of the lever e, are connected with the poles of an
electric battery.
By the clockwork A which, as stated, serves for determining the time of flow
of the current, the spring contact provided on the armature lever k is inserted
into the circuit of the induction apparatus (not shown) until the armature lever
is drawn by a spiral spring and drops into a recess in a disc (not shown) of the
clockwork A.
The lever has an adjustable armature which can be adapted to the smallest
strength of current suitable for the attractive power of the electromagnet.
After the coin has left the slot in the plate b it moves in the direction of the
arrow, Figure 2, passing first upon the lower edge g of the shoot g, and then
drops upon the lever d, Figure 3. By this means the stop lever c connected by
the adjusting screw d with the lever and which was held by the armature
lever is turned backwards. During the operation of these levers the coin has
however moved the contact lever e upwards to complete the circuit until the
armature lever is attracted and at the next moment moves the contact lever e
still further upwards and thus allows the coin to pass freely, Figures 4 and 5.
Now the coin touches the contact-breaker situated at the exit of the shoot,
whereupon the current is interrupted, the electromagnet releasing the armature k.
and the levers returning to their original positions.
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:
A coin shoot having an electromagnetic switch, wherein a lever d, on the
passage of the dropping coin, releases the armature lever k, then raises the arm i
of contact lever e to make contact with the lever f, after which the coin dropping
down the shoot touches the contact breaker h, so as to automatically interrupt
the circuit and switch off the apparatus, substantially as set forth.
