Improved Means for Preventing Fraud in Coin-freed Apparatus.
We JOHN COLEMAN of 21 Amity Road, Stratford, Essex, Watch Maker and CHARLES
STRUTT, 19 Francis Street, Stratford, Essex, Engineer do hereby declare the nature
of our said invention to be as follows:-
This invention relates to certain appliances affixable to the money slots of automatic
machines for detecting and preventing the entry of load and soft metal discs into the
machines also in certain modifications for detecting and preventing the entry of
iron washers or discs for which purpose an ordinary magnet can be balanced in
the case or box and be attracted by the iron washer or disc which would be retained
on a ledge at the entry.
For preventing the entry of lead or other soft metal discs we arrange a lever with
a wedge shaped tooth just below the slot, said lever being carried by another lever, the
front of which serves as a platform for the coin to first bear on.
the coin through the slot will tilt both levers and throw the tooth into gripping
The pressure to push
contact with the face of a bronze or a copper coin against which the tooth by the
hardness of the coin would slide but which tooth would bite into a soft metal and fix it
at the entrance.
The platform lever and grip lever have a spring connection to return them to their
proper positions after the passage of a coin.
The platform is preferably of horseshoe or other shape and may have side or edge
teeth to prevent the passage of any substitute for a coin.

Improved Means for Preventing Fraud in Coin-freed Apparatus.
We JOHN COLEMAN of 21 Amity Road, Stratford, Essex, Watch Maker, and
CHARLES STRUTT, 19 Francis Street, Stratford, Essex, Engineer 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 certain appliances affixable to the money slot of automatic
machines for detecting and preventing the entry of lead and soft inetal discs into the
machines also to means, if desire for detecting and preventing the entry of iron
washers or discs, for which purpose an ordinary magnet is balanced in the case or box
to be attracted by the iron washer or disc which would be retained on a ledge at the
entry.
For preventing the entry of lead or other soft metal discs we arrange one or more
levers each having a wedge shaped tooth just below the slot, said lever or levers being
carried by another lever, the front of which serves as a platform for the coin to first
bear on. The pressure exerted to push the coin through the slot will tilt both levers
and throw the tooth or teeth into gripping contact with the face of a bronze or a
copper coin against which the tooth by the hardness of the coin would slide, but
which tooth would bite into a soft metal body and fix it at the entrance.
The platform lever and grip lever have a spring connection to return them to their
proper positions after the passage of a coin.
The inagnet is preferably of horseshoe or other like shape and may have side or
edge teeth to prevent the passage of any substitute for a coin.
The annexed drawings show our invention.

page_text: Figure 1 is a side elevation with the platform in its normal position with a coin
resting on it.
Figure 2 represents the platform depressed and the coin passing it.
Figure 3 is a plan of the appliances and Figure 4 a front elevation of the position
the magnets occupy.
Figure 5 is a perspective elevation of the appliances looking from the rear.
A is a plate with mouth for reception of coin B. Said coin presses on the
platform Cand tumbles it into the position shown at Figure 2, said platform by its
connection with spring D and with the tail of the toothed lever E causes the tooth
to come into contact with the coin B which it rubs against if a coin proper, but which
will dig into a disc should it be of lead, or other soft metal.
The bottom end F of the platform forms a balance weight, or a spring may be
substituted to force it back into its normal position after the coin has passed
beneath it.
G is a guard to prevent the tail end F of the platform rising too far which might
otherwise happen should the coin be pushed through the slot too rapidly.
The platform (and tooth E are suspended on side levers it and to permit of the
coin passing down, said levers H are pushed away from the iront plate I, the levers
being on a pivot pin on brackets or a strap J.
The magnets K, by which the placing in of iron discs or washers is detected and
retained, pass through slots in the front plate I, and being pivotted at L are retained
out of the way by the spring M when a proper coin is inserted but are attracted to
metal, such as iron.
Should an iron washer be inserted through the slot in plate A, the action of “
tumbling lever will force the tooth E into the eye of the washe
inserted position. The pivotted magnets can be dispensed witl
Having now particularly described and ascertained the r
tion and in what manner the same is to be performed
we claim is
..it
of this inven
declare that what
1. The tumbling platform C in combination with the tooth levers E, E, as an
appliance for receiving but checking the passage of soft met I discs into coin freed
apparatus by said tooth or teeth acting against the face (not the edge) of the soft
metal disc, as described and substantially as shown on the drawings.
2. In combination with the tumbling platform and tooth or teeth E acting in the
manner described, the pivotted magnets for retaining an iron or like disc, or washer,
and thereby prevent its entry into coin freed apparatus, as set forth.
