Abstract
Abstract Coin testing apparatus for testing coins of plural denominations which initially tests each coin electronically by means of a probe. According to the denomination of coin indicated by the electronic tests, a mechanically operating sorter which corresponds to this denomination is energized to check that the mechanical properties of the coin correspond to this denomination. Thereafter a counter is operated. Whenever a bad or non-genuine coin is detected, the movement of all coins is blocked so that even succeeding good or genuine coins will not be processed until the bad coin is removed. Alternatively, coins which fail the electronic test are rejected by falling past a member which only moves into position to intercept or guide coins which have passed the electronic test. Timing stages delay the energization of a corresponding mechanical sorter for a timed period after the electronic test to allow time for a good coin to reach the mechanical sorter and for a preceding bad coin to pass by.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
Coin testing apparatus for plural denominations of coins, characterized by the combination of a. an electronic measuring and evaluating circuit monitoring a guide duct for coins, (1) said circuit producing an output signal of defined duration and characteristic for a recognized genuine coin, b. and a mechanically operating sorting device for distinguishing between genuine and nongenuine coins on the basis of an examination of the physical dimensions of the coins, (1) one of said mechanically operating sorting devices being provided for each denomination of coin being accepted by said coin testing apparatus, (2) said mechanically operating sorting devices being selectively energized electrically to perform its sorting function by the output of said electronic measuring and evaluating circuit on the basis of the denomination of coin recognized by said circuit.
Claim 2
Dependent Claim
129 words
Coin testing apparatus for plural denominations of coins, characterized by the combination of a. an electronic measuring and evaluating circuit monitoring a guide duct for coins, (1) said circuit producing an output signal of defined duration and characteristic for a recognized genuine coin, b. and a mechanically operating sorting device for distinguishing between genuine and nongenuine coins on the basis of an examination of the physical dimensions of the coins, (1) one of said mechanically operating sorting devices being provided for each denomination of coin being accepted by said coin testing apparatus, (2) said mechanically operating sorting devices being selectively energized electrically to perform its sorting function by the output of said electronic measuring and evaluating circuit on the basis of the denomination of coin recognized by said circuit.
Claim 3
Dependent Claim
43 words
Coin testing apparatus according to claim 1 wherein coins proceed by gravity flow from one testing position to the next and said apparatus includes a gravity flow duct beyond said mechanically operating sorting device having inductive means associated therewith for producing counting pulses.
Claim 4
Dependent Claim
65 words
Coin testing apparatus according to claim 1 wherein said mechanically operating sorting device includes a pivotal member positioned in the normal flow of coins to provide a measurement of the diameter of the coins, said pivotal member catching coins of one diameter and upon pivotal movement thereon delivering said coin to a gravity flow duct, but said pivotal member passing coins of a smaller diameter.
Claim 5
Dependent Claim
29 words
Coin testing apparatus according to claim 3 including means electrically controlled by the output of said electronic measuring and evaluating circuit for preventing pivotal movement of said pivotal member.
Claim 6
Dependent Claim
51 words
Coin testing apparatus according to claim 1 wherein said mechanically operating sorting device is normally positioned externally of the path taken by a coin to be tested but is movable into a coin testing position by an output signal of said electronic measuring and evaluating circuit by energization of an electromagnet.
Claim 7
Dependent Claim
65 words
Coin testing apparatus according to claim 1 wherein said mechanically operating sorting device includes means insertable into the path of travel of a coin to be tested to engage a leading edge of the coin to be tested and an auxiliary means engageable with a trailing edge of the coin to be tested to align the edges of said coin with a gravity flow duct.
Claim 8
Dependent Claim
54 words
Coin testing apparatus according to claim 1 including switch means actuated by a coin to be tested for introducing a time delay to prevent reactivation of said electronic measuring and evaluating circuit and thereby no selective reenergization of said mechanically operating sorting devices until said coin which actuated said switch means has been tested.
Claim 9
Dependent Claim
33 words
Coin testing apparatus according to claim 7 wherein said switch means is so arranged that it cannot reintroduce a time delay until said electronic measuring and evaluating circuit has produced an output signal.
Claim 10
Dependent Claim
62 words
Coin testing apparatus according to claim 7 wherein said time delay introduced by the detection of a coin by said switch means is of a predetermined length of time such that said selectively energized mechanically operating sorting device is energized by the output of said electronic measuring and evaluating circuit immediately prior to the arrival of the coin at said sorting device.
