Improvements in Automatic Coin-freed Apparatus.
I HEINRICH GARTMANN of 120 Koenigstrasse Altona in the Empire of
Germany 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 :-
This invention relates to automatic coin-freed apparatus in which the articles to
be sold (cigars, chocolate, &c.) have to pass over or between the wings or paddles
of a pair of wheels in order to fall out of the apparatus or to be removed from the
same and it consists principally of a disengaging device which by the weight of the
coin falling down through a channel allows of a rotation sufficient to release
the article for sale resting next upon the wheels.
The device is represented in the accompanying drawings.
Fig. 1 is an elevation of the apparatus partly in section.
Fig. 2 is a side elevation of the disengaging mechanism on a larger scale.
Fig, 3 is a front elevation and
Fig. 4 is a plan thereof.
Fig. 5 is a longitudinal section through the mechanism during the insertion of a
coin and immediately after the disengaging of the wheels and the delivery of the
article for sale.
Within the frame H is the upright stationary chamber P for the storage of the
articles for sale the shape of said articles or of their packing being suitable to pass
the two wheels m m' carrying the column of articles, as soon as said wheels are
brought into opposite rotary motion. The arbors w aud wl of the wheels m and m¹
rest in open journals as may be seen by the drawing and one of the wheels is
provided with a pin wheel by which the stopping of the wheel appertaining
thereto is effected, one of the pins i of the wheel h resting upon the slides as shown
by Fig. 2. This slide s is prolonged at s¹ to pass the side of the wheel hand carries
a projection in front, which again projects underneath the pins of the wheel h
as shown by Fig. 4.
The slides is suspended on two light vertical vibrating arms or springs B and B'
which are suitably arranged at the opposite narrow sides of the coin channel K.
The one spring B' has a bend a entering into a notch e of the coin channel K
and is adjusted in such a manner that it tends to press the slide towards the pin
wheel h.
If a suitable coin G is introduced into the channel K the former falls downwards,
touches the projection of the spring B and pushes the same outwards in
descending. The outward motion of the spring B' compels the slides fastened
thereto to move to the right, and releases the pin i of the wheel said pin resting
The weight of the column of articles revolves the wheels mm' and an
article A falls into the channel o and appears in front of the apparatus.
upon s.
In order that on each stroke of the spring B' only one article A can fall out, the
projection previously referred to is arranged at the end of the slide. At the
moment when the slide s moves to the right upon the touch of the coin upon
the spring B', the projections located somewhat lower than s moves also so far to
the right that, as shown by Fig. 5 one of the moving pins of the wheel h
touches against this projection and thereby limits the motion of the wheel h
to the necessary amount.
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 :-

projection which enters into a notch of the coin channel to be moved by the 5
descending coin substantially as and for the purpose set forth.
