Improvements in Apparatus for the Receipt of Coin and for the
Delivery of Goods in Exchange therefor.
We FRIEDRICH SCHILLING and JOHANN GEORG ADOLF BRÜNING of the firm of
Schilling and Brüning of Bremen 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 apparatus for the receipt of coin and for the delivery of
goods in exchange therefor the said apparatus being chiefly intended for the sale of
cakes of chocolate and the like.
Our said invention is illustrated in the accompanying drawings the Figures of which
are hereinafter referred to.
Figure 2 is a plan and
Figure 3 is a transverse section of the drum t which is divided into four compart-
ments in each of which a pile of small cakes of chocolate c is placed.
This drum revolves on the shaft a and at each revolution of the same one of the
small cakes of chocolate or the like comes in contact with a pin s fixed in a bed plate
and is thereby pushed forward, while the cakes above the one which is being thus
displaced as it passes above the said pin s are kept from descending as shown in
Figure 4. Nor is it possible to remove any one of those cakes from the outside
without having first deposited the proper coin for it in the apparatus owing to the
transverse partition 9 Figure 4 fixed to or forming part of the rotating drum t so that
the lowermost parcel of chocolate will be behind the said strip and cannot be extracted
by anyone through the narrow opening in the outer casing of the apparatus as seen in
Figure 3.
The revolution of the drum t is caused by the lever handle pivoted at a Figures 1
and 2 by which the excentric ring Figure 1 is turned round the shaft.
While the said is thus made to revolve a pawl s movably attached thereto
catches one of the 4 pins y projecting from the disc 8 which turns upon the bed
plate band in the centre of which drum the shaft a is situated.
A bent piece w is fastened to the ring and is provided with indentations which
prevents the lever-handle from being turned back before the full stroke is accomplished
otherwise were such a reversing movement attempted they would catch one of
the pins y.

page_text: The said ring is also provided with a piece which is to prevent the drum being
moved further than is required. The play of the handle is limited by the pin c
fixed upon the feeding rod z which only becomes movable by a coin of proper size
being dropped through the slot e Figure 7 so that it is conducted by channel k
Figure 3 into a hole of elongated shape and angular at the end as shown in Figures 5
and 6.
The said hole is formed by a slit u provided in the bed plate b as is clearly shown in
Figures 5, 6 and 8.
The coin is then caught either by the spring 9 Figure 5 or by bar which is
maintained in position by spring pressure, and provided with an angular notch. This
interposition of the coin lifts the hook or lever and prevents the connecting or
feeding rod carrying the pin c from being kept stationary by the said hook
engaging in a notch in the said rod z and consequently permits the rod z to slide and
the crank to revolve. Whereas if there is no coin in the slit u the hook will be
pressed into engagement with the notch in the rod z and thus prevent the operation
of the handle h. To the rod is attached a guide plate m bent to an incline which,
while rod slides forces the coin through the slit an arrangement which is best
illustrated in Figure 8.
In Figure 6 the guide plate m is shown in a position to engage with a pin fixed to
guide bar i, whereby it forces back the latter, so that the coin can fall through.
Another object of plate m is attained when two coins are inserted at one time in which
case it will place itself under the second coin, and prevent the working of the same
until another pull enables it to pass in its turn.
Figures 9 to 12 show enlarged views of the operating mechanism.
The bar Z is moved against the pressure of the coiled spring by the handle h
bearing against the pin c.
I is the latch or catch held against the pin 2 by the spring as formerly described.
The original or "normal" position is that shown in Figure 12. There is no coin
inserted. If now the lever and thereby the bar z are moved to the left the spring
acting upon the latch 7 will press the latter downward and this latch held in contact
with the pin 2 on the moving bar will engage with the said pin 2 and arrest the
further motion of the bar z as shown in Figure 10 so that the mechanism cannot be
operated.
But if a coin is inserted in the slot u as shown in Figure 9 the lower straight
surface of the "latch" I will come in contact with, and ride on, the said coin, and its
front hook will thus be lifted out of contact with the pin 2 so that the latter and its
connected bar z will not be arrested and the mechanism can be put in operation.
In Figures 4 and 7 a device is shown as applied to our improved apparatus, the
object of which is to prevent the further insertion of coins when the supply of goods
is exhausted.
Figure 7 shows the door or front wall of the apparatus from the inside. On a
bracket screwed to the said door is pivoted the elbow lever n, the one arm of which is
direct, outwards from the door, whilst the other arm is underlying the pin S² on the
slide S³ closing the slot e when dropped.
Figure 4 shows the plate p on top of the chocolate-packages when the same are
nearly sold out. The plate p has a tail-piece extending out of the compartment containing
the chocolate packages through a longitudinal vertical slot each in the said compart-
ments. When the chocolate is about sold out the tail-piece of the plate p which is
then in the same horizontal plane with the arm of the lever n and which may be
suitably inclined in the vertical direction will strike against the said arm and turn the
lever on its pivot n* so that the other arm of the lever arm n underlying the pin S²
in Figure 7 will be drawn from underneath that pin. By this means the slide S³ to
which pin S² is fixed is no longer supported and is allowed to drop down, so that the
upper angular end w of the guide plate closes the slit e provided for the insertion of
coins and the lower angle w¹, closes the opening for the issue of chocolates. The
spring accelerates the fall of guide plates and pawl s prevents guide plate s³
from being worked by outsiders.

page_text: The full lines in Figure 7 show the plate s raised and the dotted lines show it in its
"dropped" position. This part appears to be quite clear. When the plate s³ drops
and closes the outlet opening of the apparatus and the slot for introducing the coin,
the pawl or lever s will assume a horizontal position on account of the greater weight
of the long arm and will engage with a pin or stud 1x the other end of lever s¹ enters
into the notch in the plate 3 as shown in dotted lines in Figure 7. The lever or
pawls cannot be raised again except from the inside after opening the door of the
apparatus and therefore locks the plate 3 efficiently.
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 the receipt of coin and for the delivery of goods in
exchange therefor, the combination of a drum provided with compartments for cakes
of chocolate and the like with a stationary pins by which when the drum is turned
round one of the said cakes of chocolate or the like will be moved forward while at
the same time it prevents the exit of the remaining cakes substantially as above
described.
Second. The means substantially as above described for causing the drum to
revolve which consists in the arrangement of a lever-handle h whereby an eccentric
ring is rotated and the shaft of drum t caused to revolve by means of the pawl s*
above described.

Third. The slit or slot u provided with an angular end and designed for the
reception of coins, in combination either with spring g or with movable guide bar or
plate i for the purpose of enabling the handle h by the disengagement of hook 7, to
have its full play and thus to bring about both the forward motion of pin c and
rod z and the revolution of the drum substantially as described with reference to the
drawings.
