Improvements in Automatic Sale Apparatus.
I, GEORG ADOLF SINSEL of Leipzig 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 coin-freed sale apparatus and has for its purpose to provide
a device for preventing such apparatus being operated without the coin or coins
required therefor having been introduced, the coin passage to be obstructed or the
machine to be rendered inoperative for the public by other similar injurious inter-
ferences. Mechanical sale apparatus are liable to be tampered with for instance by
producing the operation referred to by tying a coin of predetermined value fit to
actuate the apparatus to a thread and sinking it into the coin receiving passage,
thereby disengaging the slide and obtaining any number of the respective articles
without pay, the said coin being drawn up each time after the slide is released.
The improved contrivance intended to render similar frauds impossible is applicable
to all kinds of coin-freed sale apparatus.
Referring to the accompanying drawing
Fig. 1 is a longitudinal section through the coin receiving device portion of the
apparatus ready to take the coin.
Fig. 2 the same with the coin receiver pressed down to transmit the coin into the
coin passage proper..
Fig. 3 is a rear view, and
Fig. 4 a front view of the device as represented in Fig. 1.
Fig. 5 is a cross section along line O O Fig. 1 ;
Fig. 6 a cross section along line PP Fig. 2.
The improved safety device consists in the following disposition
:-
A box A is provided on the outside of the apparatus before the mouth of the coin
passage thereof. Said box contains a displaceable coin carrier B furnished with a
peg d projecting through A into the interior of the apparatus and connected with a
spring. A hook E serves to detain the peg d and thereby the coin holder B when
depressed, until the latter is allowed to re-ascend by the action of spring f, on the
slide F, Fig. 2, being drawn out to take out the article purchased, whereby the lever E
is caused to release the peg d through the nozzle g provided on the slide.
The coin carrier when occupying its highest position serves for receiving the coin
through its slots a which are then open Figs. 1 and 4. The coin introduced into one
of the latter is allowed to descend into the apparatus only on the depression of the
coin carrier as illustrated by Fig. 2.
The coin now rolls over the inclined plane e down through passage D and
operates the slide releasing mechanism in a suitable manner.
The application, to automatic sale apparatus, of the above described contrivance,
precludes a repeated operation of the inachine and delivery of articles by means of
one and the same coin, as, through the displaceable coin holder B any influence on
he coin put into the latter from outside the machine is rendered impossible as soon
as the coin occupies the position in which it is transmitted to the main coin passage.
The improved attachment may be advantageously applied to automatic sale machines
every description, either independently or in combination with the constituent
nechanism of the main apparatus.

page_text: Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A safety coin supply device for mechanical sale apparatus, consisting of an attach-
ment or casing A provided before the main coin passage and containing a vertically-
displaceable coin receiver or holder B, which has coin slot or slots a and serves as
a medium for transmitting the coin to the main coin passage of the apparatus, sub-
stantially as and for the purpose set forth.
