Improvements in Coin-testers for Coin-freed Machines.
We, PHILIPP REINER and JOSEPHI PELZER, Manufacturers, of the Allgemeine
Automaten Gesellschaft Reiner Pelzer & Co., of Ehrenfeld, near 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 a coin-testing attachment to automatic delivery
machines, which has this in common with existing arrangements of the same
class, that it is intended as far as possible to allow coins of a pre-determined
value only to pass through for the purpose of operating the automatic delivery
mechanism, whilst eliminating coins of inferior value, and more especially those
which are either too thin or too small, or imitations of or substitutes for coins of
aluminium, iron, paste board, paper or the like.
The improved coin-tester is represented in the accompanying drawings in which
Fig. 1 is an elevation or perspective end view from the interior of the machine;
Fig. 2 a side view of the coin-tester in the position of rest;
Fig. 3 the same at the moment of the insertion of a coin;
Fig. 4 a side view corresponding to Fig. 2, but from the opposite side;
Fig. 5 is an end view showing the position, when a coin is being inserted;

Fig. 9 a section along line Z-Z of Fig. 3.
The main novel feature of the invention is that a plate a suitably secured to
the plate A in an inclined position, as shown by Figs. 1 and 6 to 9, is fitted with
a hinged flap g influenced by a magnet, and with step-shaped projections or off-
sets a¹ and a forming the channel or race for the coin to travel in, and both termi-.
nating in one step at the outlet end of the plate a.
Under the said projections of the plate a and parallel thereto a rail d is arranged
to pivot on a lateral axle, b, the front end of which forming a flange d¹ comes to
be situated somewhat higher than the off-set a², so as to form a groove a³.

which extends uniformly from end to end, thin coins, which will sink down into
the groove and thereby loose the support or guidance afforded by the flange e²
of the rail e above them, Fig. 8-(which rail shall be more fully described fur-
her on) instead of dropping out of the coin sorter, remain suspended therein,
nd must inevitably be ejected, no matter how quickly they may be followed
y a newly inserted coin, for owing to the peculiar displacement of the lower
ail d supporting the travelling coin Fig. 9, the inferior token is allowed to drop
ut sideways.
In case of coin-testers forming a continuous slot, so as to cause coins which
re too thin to pass through, the defect occurs, that such a coin when it has sunk
own into the slot, but not fallen through, has not time to become ejected alto-

frequently happens, is that the coin is caught again between the two rails which
are thus quickly brought together, so that it actually prevents the next-follow-
ing coin from passing through and naturally disarranges the mechanism.
Parallel to the lower rail d, the second rail e, already mentioned above, is
arranged in a raised position on the plate a, to which it is attached by means
of a hinge in the same manner as the rail d. The rail e is fitted with arms e¹
and 3, while the rail d has a curved arm h, an upright arm d², and a projec-
tion extends above the lower edge of the coin-inserting slot, so that each coin,
as it is inserted depresses such projection, Figs. 2 and 3. At the back of the
plate a is secured in a suitable position a magnet f, the poles of which are facing
the path or race of the coins.
A flap g is furthermore hinged to the plate a opposite to the magnet f, by
which it is influenced; by means of a lateral pin or runner gl (Figs. 1, 2, 3, 8,
9) and a slotted angle piece the flap rests upon the rail e and is so operated by
this rail, that whenever the rail is raised, the flap g must be raised also. While the
coin-tester is closed, the hinged flap g has sufficient freedom of motion, to enable
the thickest coin that can be passed through the inserting slot to pass also
between the said flap and the plate without any difficulty.
Now, when a coin is inserted into the slot, the rail d is depressed through the
medium of its projection i, as before stated, when the arm d² will act on the
arme of the rail e and thereby raise such rail. As the rail e rises, it presses upon
the stud g of the hinged flap g, which in consequence of the motion transmitted
to it is opened wide enough to remove every point of support out of the way of
coins, or substitutes for coins, which may have remained suspended near the slot,
so that they must infallibly drop out sideways.
When the coin has passed the insertion slot, the coin-tester closes under the
action of two suitably arranged springs and (Figs. 1 and 4), and the coin
now takes up its position between the hinged flap g, and the magnet f, the poles
of which are flush with the plate a. If what has been inserted is the right coin
or a full-weight imitation of such a coin, except where the spurious article is
iron, it will force the hinged flap g, which is retained by the magnet, to one
side, and proceed further along its course, while the coins which are too light,
or iron imitations, will be detained between the hinged flap and the magnet, so
that when the next coin is inserted, they must be expelled in the well-known
manner, as the coin-race opens, by means of the arm h which gets between the
poles of the magnet.
If the coin is of sufficient weight to force the hinged piece away from the
magnet f, but too thin, Figs. 8 and 9, it will sink down into the groove a³
and thereby get clear of the flange e² of the upper rail e, so that it must overturn
and drop laterally out of the coin-race; but if the coin, although it has descended
into the groove ³, should not overbalance itself altogether, but merely be tilted
somewhat to one side, whilst continuing to roll along its path, it will presently
be forced sideways against the flange by the wedge-shaped lower extremity a
of the projection ², so that the coin becomes jammed between the flange d¹ and
the said wedge, whereby the further progress of the coin is checked, and when
the next coin is inserted, this one must drop out, owing to the oblique position
of the plate a.
If the coin inserted should be too small in diameter, it will also fall out side-
ways; but if it should fail to do so and continue to roll down in a slightly tilted
position, it will presently be stopped by the arm el of the rail e (Fig. 1), and
must drop out, either immediately or when another coin is inserted.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. A coin-tester for coin-freed machines, having the characteristic feature, that

page_text: the insertion of a standard coin causes the shoot which has an extension i, to
change its shape, so that unsuitable coins still adhering to the shoot may drop
out, the said tester comprising in its construction a stationary plate a provided
with steps a', a², and with a pair of rails d and e adapted to turn on axles band e³,
the rail d having a bend or Hange and serving in conjunction with the step a³
to test the thickness of the coin, while the rail e in conjunction with the step a³
serves to test the diameter of the coin.
2. In a coin-tester of the type specified, an upper rail e having at its delivery
end an arm e adapted to prevent too small coins from rolling through, after
having emerged from the upper guide, substantially as described.
3. In a coin-tester of the type described, a flap g and a magnet f arranged so
that the coins must pass between the same after their insertion into the coin slot,
the said flap being attracted by the magnet and adapted to stop too light coins,
which latter are subsequently ejected by the arm h in the known manner, when
the next standard coin is being inserted, substantially as described.
4. A coin-tester of the type specified, having at the delivery end of the steps a¹
and a² a wedge piece a adapted to close the groove a³ and thereby to prevent the
passage of coins which have dropped into the groove a³ and arrived beneath the
ledge, substantially as described.
