An Improved Coin-freed Sale Machine.
I HERBERT JOHN HADDAN of the firm of Herbert & Co. Patent Agents of 18
Buckingham Street, Strand W. London in the County of Middlesex Civil
Engineer do hereby declare the nature of this invention a communication to me from
abroad by Julius August Soetje of No. 33 Kleine Bückerstrasse, Hamburg, in the
Empire of Germany Manufacturer and in what manner the same
performed to be particularly described and ascertained in and by the following
statement:-
is to be
This invention consists in an apparatus or machine which by the insertion of a
coin of a specified size and weight, delivers an article to be sold. The articles to be
soll of different assortment are stored separately in compartments in the periphery
of a drum, said drum being adapted to receive a rotary motion within a case and
expose the articles to view in such a manner that they may be seen from without.
After selecting the article which one desires to purchase, the purchaser turns the
drum by hand so that the compartment of the drum containing the respective
article is placed in front of the delivery opening arranged in the case, he then
inserts the coin into the slot arranged for this purpose on the apparatus. The coin
falls through a channel into a box and acts in this box by its weight upon a
mechanism in such a manner that the same is disengaged and the article falls out of
the machine.
The device is represented in the accompanying drawing, Fig. 1 is a front view in
section, Fig. 2 an outside view partly in section, and Fig. 3 is a side view in
section.
B is a rotary drum fastened on the arbor w and rotated by the hand-wheel H.
This drum has on or in its circumference the divisions or compartments f formed
by radial walls c, to receive the articles to be sold. The drum is open in front, so
that the articles are exposed to view through a window S. In the lower part of
the case A is an opening e, through which after the insertion of the coin the
respective article should fall from the compartment placed above it. Underneath this
opening e are journalled in the frame the two arbors m and m¹ of which m carries
the two arms ii and m¹ the arms i¹¹. These arms project by means of the counter
weights g and g' underneath the opening e and prevent the article arrived above e
from falling from the drum. The opening of the arms and and the falling out
of the article takes place by the following mechanism.
The coin previously tested as to its size arrives from the channel into the box P
located against its lower end and by its weight presses the same and its lever
downwards; said lever rotates on pivot s and is kept by a counter-weight against
the channel k as long as the coin has not reached the box. The lever e presses down
the lever o by means of the pin and said lever o operates with a cross-bar z upon
the crossing levers y and y', which are secured on the shafts m and m¹. As soon as o
descends the shafts m and m³ rotate and with the saine the arms i and it. The
latter arrive into the position shown in dotted lines in Fig. 1 and free the opening e
at the same time, so that the article may fall from the compartment of the drum
located thereover. The object falis forward on the slant h (Fig. 3) and appears at
an opening a of the machine.
When the box p with the lever v has reached the lowest position, the former touches
against a stationary pin 3; the frame of the box is lifted and the coin falls out as
shown by Fig. 1. In order to prevent a second compartment f of the drum being
brought in front of the opening e, before the latter is shut again so far that the
article located therein does not fall out without further payment, the following device
is adopted.

page_text: The article falling from the drum after the coin has been inserted reaches first the
crossing lovers (see Fig. 2 dotted lines), which rotate on the pivots d d² and are
kept in the crossed position by the counter-weights u u' as long as no additional
weight is added by the article fulling from the drum. But as soon as the latter
takes place, the arms are separated and the respective article fulls down between
the arms and brings the latter into the position of Fig. 2 shown by plain lines. The
arms being extended beyond their fulcrum and their ends angularly bent, the
angles or hooks pass underneath the opening and prevent the falling out of a
further article whilst giving time to the arms to return to the original position
Fig. 1. As soon as the article is withdrawn from between the arms the latter
return to their crossed position. Now by the insertion of a further coin a further
article can be taken.
Having now particularly described and ascertained the nature of the said inven-
tion and in what mannor the same is to be performed, 1 declare that what 1
claim is :-
A coin-freed machine comprising the drum 13 provided with the compartments f
which former rests within the case A and which can be rotated, in order to place
the respective article required in front of an opening of the case, the box p for
receipt of and operation by the coin, the lever attached thereto, the double levers i
closing the opening e, and the safety-levers, the whole substantially as and for the
purnoses described.
