Abstract: 642,413. Counting-apparatus. HAYES, T. E. July 11, 1947, No. 18526. [Class 106 (i)] A machine for counting paper money has a plurality of bill receiving compartments each provided with a counter operated by bill feeding means, a totalizer actuated by the counters, and means adapted temporarily to halt the bill feeding means on the registering on any counter or on the totalizer of the last of a predetermined number of bills and further means, operable on registration by the totalizer of the last of the predetermined number of bills, to stop the bill feeding means when the last bill has been fed into the machine. The machine is similar to that described in Specification 627,101, and is driven by an electric motor 10, the circuit of which includes (see Fig. 9) the starting switch 31, normally closed contacts 48, 49 of a relay 50, normally closed contacts 57, 58 of a switch 56, normally closed contacts 60, 61 of a relay 62, normally closed contacts 64, 65 of a relay 66 which co-operates with a relay 67 as described later. Actuation of a micro-switch 27 by the passage of a bill between two rollers 7, 8 (Fig. 2, not shown) completes a circuit through the normally closed contacts 78, 79 of a counter relay 80. The associated counter armature 84 is thereby rocked clockwise closing contacts 86, 87 establishing a circuit to the totalizer 29, the armature 93 of which rocks clockwise closing contacts 95, 96 to energize the counter relay 80 which raises its armature separating contacts 78, 79, breaking the circuit to the actuated counter 28 and totalizer 29 which are thereby actuated before the operator can present another bill to the feed rollers. The contact 78 now engages the contact 101 to establish a holding circuit for the relay 80 to ensure that contacts 78, 79 are kept separated until the bill has passed between the rollers. The " tens " wheel of each counter is provided with a small cam between the numerals " 9 " and " 0 " which as the count passes from " 99 to " 100 " closes contacts 106, 107 establishing a circuit to the coil 113 of a relay 62 whose armature moves upwardly, is latched by a latch 126 and so separates contacts 60, 61 breaking the motor circuit, closes contacts 122, 123 to complete a circuit to a brake 33 which acts as described in the above-mentioned Specification 627,101 to stop the motor. Contacts 124, 125 are closed to complete a circuit through a thermostatic conductor loop 136 which heats and expands to close contacts 137, 138 to set up a circuit to and energize a coil 145 which then withdraws the latch 126 from the armature of relay 62, reclosing contacts 60, 61 to re-establish the motor circuit. The totalizer 29 has two cams on its " tens " wheel which effect closure of contacts 150, 151 when the totalizer registers " 50 " and " 100." A circuit is thereby established to a latch coil 157 and a latch 159 is withdrawn from its associated armature which falls and thereby closes contacts 160, 161 to prepare a circuit to a coil 162 so that upon the registration of " 100 " on the totalizer and closing of contacts 150, 151 a latch is withdrawn from the armature of the relay 66 and contacts 64, 65 are separated to break the motor circuit and simultaneously by closing contacts 168, 169 establish a circuit through contacts 48, 49 to the brake 33 and by closing contacts 64, 172 to establish a circuit through relay contacts 57, 58, contacts 60, 61, contacts 175, 176 of relay 50 through a thermostatic conductor loop 178 which heats and expands to move an arm 184 and close contacts 185, 186 to complete a circuit to energize a relay coil 190 which raises its armature to separate contacts 48, 49 interrupting the brake circuit. Closure of contacts 48, 192 establishes through contacts 181, 182 a holding circuit for the relay 50 to maintain the armature in the up position in which it closes contacts 193, 194 establishing a new circuit to the motor 10 which restarts to pass the hundredth bill completely between the rollers, whereupon the corresponding micro-switch 27 opens breaking the holding circuit of relay 80, the armature of which falls to separate contacts 181, 182, breaking the holding circuit of relay 50, the armature of which then separates contacts 193, 194 reclosing contacts 48, 49 breaking the new motor circuit and re-establishing the brake circuit. The operator then presses the button 32 to establish, through contacts 64, 172 a circuit to a solenoid 19, Figs. 3 and 9, which through a lever 17 rocks a shaft 15 to open compartment shelves (not shown) dumping the bills into their compartments. Movement of the lever 17 effects closure of contacts 199, 200 to establish a circuit to the coils 205, 206 of the relays 66, 67 and re-establish the original motor circuit. If it is desired to stop the machine when fifty bills are counted on the totalizer, the relays 66, 67 normally in series are also connected in parallel by closure of a switch 211 and operate simultaneously upon closure of contacts 150, 151. Excess movement of an upper roller caused by passage of a folded bill or of two bills effects movement of a two-piece lever 56 to separate contacts 57, 58, breaking the normal motor circuit and closing contacts 57, 222 to establish a circuit to the brake 33. Instead of using thermostatic means to control the stoppage time of the motor 10 as above described, the relays 50, 62 may be provided with a known type of motor-operated delay mechanism. Indicating means comprising a light may be provided to show when a counter registers a hundred.
