Improvements in Automatic or Coinfreed Delivery Machines.
We, PHILIPP REINER and JOSEPH PELZER, of the Firm of Pelzer & Co., Manu-
facturers, of Ehrenfeld, Cologne, in the German Empire, 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 delivery machines provided with inclined
shelves containing the goods to be sold.
In the accompanying drawings:
Fig. 1 is a side view of a machine embodying this invention; Fig. 2 is a front
view of one machine and a partial front view of another machine, showing two
different types of our invention; Fig. 3 shows one of the shelves as it would appear
in a section along line - of Fig. 1; Fig. 4 is a diagram of a double machine.
The machine chiefly comprises one or more series of shelves a inclined at such
an angle, that the goods placed on the same will descend by their own weight, if
they are allowed to escape, and means for controlling their escape from the shelves.
To prevent the goods from dropping out of the shelves accidentally, the front
of the shelves is partly closed by a steel band b, which is attached at the upper end
to a drum c and loaded at the lower end by a weight d. The said steel band is
guided vertically by means of recesses a¹ formed in the front edge of each shelf,
as illustrated by Fig. 3.
The drum c is mounted on a shaft adapted to be set in motion by the insertion
of a standard coin, in the well-known manner, each insertion causing the metal
band to be drawn up for a given distance corresponding to the height of a com-
partment or the distance between two shelves. Consequently, every time a coin.
is inserted, one of the compartments between the shelves is laid open, and the
article mounted on the corresponding shelf is allowed to escape. This operation
may be repeated, until the band is completely wound up.
Instead of one flexible band, two or more parallel bands may be used for closing
the shelves.
In the machine described above and illustrated by the left half of Fig. 2, each
compartment contains only one article to be delivered, and the band is raised for
the entire width of a compartment at each insertion of a coin.
In order to sell as many articles as possible by means of the same mechanism,
the construction may be modified in the manner illustrated by the diagram Fig. 4,
which represents a horizontal section of a duplex machine. In this machine the
shelves are made wide enough to receive side by side two articles for sale, for
instance, thin plates or sheets e, e, and the band b is so arranged, as to overlap the
inner edges of the same. The weight attached to the lower end of the band b
has a projecting edge da, which occupies half its width, as shown by Fig. 2, while
the remaining half d, is situated in a recess. The mechanism for turning the
drum c is so adjusted, that at every insertion of a coin, the band will be drawn up
a distance equal to half the depth of a compartment formed by the shelves, and the

page_text: edges d¹ and d² are so arranged, that they will alternately obstruct their respective
compartments. Consequently, if the article on the left, or the left hand compart-
ment, is laid open by the insertion of a coin, the insertion of the next coin will
lay open the right hand article or right hand compartment, so as to allow the
article on the right hand to slide out, while that on the left is held back.
As the coin-controlled mechanism, for turning an axle a given distance is well-
known it need not be described.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. A coinfreed or automatic delivery machine, comprising in its construction
a series of inclined shelves or compartments placed one above the other, and con-
taining the goods to be sold, substantially as described.
2. A coinfreed or automatic delivery machine, comprising in its construction a
series of inclined goods shelves or compartments placed one above the other, and
a metallic band adapted to move across the lower openings of the said compart-
ments, so as to uncover them one by one, substantially as described.
3. The various forms of coinfreed delivery machines having inclined shelves and
a metal band, controlled by coinfreed mechanism, substantially as described.
