Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
132 words
In combination, in coin processing apparatus, chute means transporting coins therethrough, coin sensing means in said chute means including a first sensor generating output signals for indicating coin size and a second sensor generating output signals for indicating the position of each coin in said chute means, each of said output signals being of first character when a coin is in transit through said sensors and otherwise of second character, motive means supplying coins to said chute means and a system for detecting the occurrence of a coin jam in said apparatus and for thereupon discontinuing operation of said motive means, said system including circuit means deenergizing said motive means on each occurrence of a second sensor output signal of said first character and of time extent exceeding a predetermined time period.
Claim 2
Dependent Claim
132 words
In combination, in coin processing apparatus, chute means transporting coins therethrough, coin sensing means in said chute means including a first sensor generating output signals for indicating coin size and a second sensor generating output signals for indicating the position of each coin in said chute means, each of said output signals being of first character when a coin is in transit through said sensors and otherwise of second character, motive means supplying coins to said chute means and a system for detecting the occurrence of a coin jam in said apparatus and for thereupon discontinuing operation of said motive means, said system including circuit means deenergizing said motive means on each occurrence of a second sensor output signal of said first character and of time extent exceeding a predetermined time period.
Claim 3
Dependent Claim
54 words
The invention claimed in claim 1 wherein said circuit means includes a capacitor, a first circuit for charging said capacitor exclusively during the occurrence of second sensor output signals of said second character and a second circuit for discharging said capacitor exclusively during the occurrence of second sensor output signals of said first character.
Claim 4
Dependent Claim
37 words
The invention claimed in claim 2 wherein said circuit means further includes a third circuit monitoring the voltage across said capacitor and operative to deenergize said motive means when said voltage is less than a predetermined voltage.
Claim 5
Dependent Claim
50 words
The invention claimed in claim 3 wherein said motive means includes an electric motor and a motor energization circuit, said third circuit including normally-conductive switch means series-connected in said motor energization circuit, said third circuit rendering said switch means nonconductive when said capacitor voltage is less than said predetermined voltage.
Claim 6
Dependent Claim
47 words
The invention claimed in claim 1 wherein said apparatus includes a further system for detecting the transit of a preselected number of like coins through said sensing means and for thereupon interrupting transit of further coins through said sensing means and discontinuing operation of said motive means.
Claim 7
Dependent Claim
100 words
The invention claimed in claim 5 wherein said further system includes coin stopping means in said chute means, first circuit means responsive to said first and second sensor output signals to generate output signals indicative of the denominational value of each coin in tRansit through said sensing means, second circuit means responsive to said first circuit means to provide an output signal upon the transit of said preselected number of like coins through said sensing means, and third circuit means responsive to said second circuit means output signal for energizing said coin stopping means and for deenergizing said motive means.
Claim 8
Dependent Claim
51 words
The invention claimed in claim 6 wherein said motive means includes an electric motor and a motor energization circuit, said third circuit means including normally-conductive switch means series-connected in said motor energization circuit, said third circuit means rendering said switch means nonconductive on occurrence of said second circuit means output signal.
Claim 9
Dependent Claim
23 words
The invention claimed in claim 6 wherein said further system includes indicator means energized on occurrence of said second circuit means output signal.
Claim 10
Dependent Claim
41 words
The invention claimed in claim 6 wherein said second circuit means includes a counter generating said second circuit means output signal, said further system including fourth circuit means operator-controllable to reset said counter after each second circuit means output signal generation.
