Abstract: 825,813. Cash registers. NATIONAL CASH REGISTER CO. Feb. 25, 1958 [April 1, 1957], No. 6045/58. Class 106 (1). [Also in Group XVIII] A cash register of the Shipley type records multiple or single items of sale and the amount tendered and has an addsubtract totalizer which, if there is a negative balance, sets up circuits for operating solenoids which control appropriate latches so that spring- driven ejectors are freed to deliver the appropriate change from one or more of several coin magazines. Mechanism for printing a sub-total is provided. The gear segments for operating the indicators of the register from the amount differentials are coupled to rotatable switch contacts for the solenoids 130-137, Fig. 10B, the segment for the 10-cent bank rotating three wiper arms 106-108, Fig. 10A, and the segment for the 1-cent bank rotating five wiper arms 109-113. The coins to be ejected are stacked in magazines 151 for denominations as indicated against solenoids 130-137 in Fig. 10B and are ejected from each magazine by a member 153, Fig. 8, pivoted on a rocking arm 157. The arm 157 is spring-loaded into engagement with a stud 160 on an arm 161 pinned to a shaft 158 and when the shaft 158 is rocked first counterclockwise and then clockwise, the stud 160 releases the arm 157 for movement by its spring to eject a coin or coins and then returns the arm to initial position. If, however, the solenoid, such as 131, corresponding to the magazine is not energized, a hook 162 moves into position to engage a stud 163 on the arm 157 and prevents coin ejection from that magazine. The shaft 158 is rocked by a connecting rod 171 and arm 170, Fig. 7, through a onerevolution clutch 174 driven by a motor 181 and initially engaged by the momentary energization of a solenoid 189 through a switch 280 which is closed during a total-taking operation. The motor 181 is operated at the proper time through a switch 138 which is closed during a negative total-taking operation, through a switch 200 which is closed during a total-taking operation and through a switch 210 which is closed when the register is released for operation. Release of the register rocks a lever 214, Fig. 6, from under a spring-loaded lever 216 so that a spring-driven cam 219 is free to rotate and cause simultaneous closure of the switch 210 and of a switch 235 of a motor for driving the register. A " no-coin " switch 240 in the circuit of the motor 181 is opened if any one of the coin magazines becomes depleted so that a feeler arm 245 can enter fully into the magazine or if a cover 152 over each coin magazine is removed after depressing a notched latch 255 having a stud 259 bearing on a lever 260 on the same pivot as the feeler arm. As the level of the coins in a magazine becomes low, a notch 314 on the feeler arm passes over the top of the coins and a switch 313 is closed so that a warning lamp 310 is lit. The feeler arms 245 are spring-pressed against the coins and to relieve this pressure during operation of the register a link 341 to the shaft 158 rocks the arms counterclockwise. To ensure that the " no-coin " switch 240 does not prevent operation of the motor 181 before the clutch 174 and shaft 158 have returned to initial position, a by-pass circuit through a solenoid-operated switch 300 and holding switch 305 is provided. When a single 1-cent coin is to be issued as change, the corresponding indicator segment has set the wiper arm 113 to the " 1 " contact 127 and the solenoid 133 is energized by current from a rectifier 275 which is energized at the same time as the motor 181. If the 1-cent segment has been set to " 5," solenoid 136 will be energized, the circuit including the " 5 " contact 124, wiper arm 111, " 0 " contact 117, and wiper arm 107. If the 1-cent segment has been set to " 4," solenoids 131 and 132 will be energized, the circuit including the " 4 " contact 125 and wiper 112 and the " 4 " contact 126 and wiper 113. Although the wipers 109, 110 and 111 will also have been set to the " 4 " position at this time, no completed circuit from these wipers is available and their corresponding solenoids are not energized.
