Patent GB-200062-A (GB)
Abstract: 200,062. Krupp Akt.-Ges., F. July 3, 1922, [Convention date]. Adding-apparatus; cash registers with operating-means; error keys.-In machines in which the depression of one of the special keys releases the machine for operation, the levers actuating the locking plates to release depressed keys in the amount key-banks are adjustable so that they do not function unless the depressed special key has been previously released. Each amount key a<1>, Fig. 4, is provided with pins b<1>, c' on either side engaging a locking plate b<2> and a plate c<2> respectively which are normally urged downwards by springs. When a key a<1> is depressed both plates are moved upwards and the plate b<2> snaps back over the pins b<1> locking the depressed key and also locking the plate c<2> in the upper position. The movement of the plate c<2> releases a latch l<3> pivoted at l<2> from a lug m<3> on the bolt m<1>, and also frees a latch n<3> which allows the pivoted arm n<2> to swing to the left, Fig. 9, under the influence of the spring n<4> when the pin o<2> on the differential sector o<1> has cleared the end of the arm m<2>. The shoulder o<3> engages the end of the bolt m<1> and carries it upward until the bolt is released from the sector o<1> by the engagement of the lug m<4> with the stem of a depressed key. The locking plate b<z> has a lug b<6> which lies in the path of a lever e<2> pivoted to an arm e<3> on a shaft e<4> and slotted to engage a pin f<1> on an arm f<2> carried on the shaft f<3>. Normally, the shaft f<3> is rocked by a cam f<7> and lever f<4> towards the close of an operation, and the levers e<2> engage the locking plates and move them to release depressed keys. When one of the special keys a<2>, Fig. 6, is depressed, the shaft e<4> is rocked and the levers e<2> are moved to the right, Fig. 4, so that they fail to engage the lugs b<6>. This is effected by movement of the detent plate h<1>, Fig. 6, of the special key-bank through the arm e', link e<5>, and arm e<6>. A further arm e<9> on the shaft e<4> is connected by a link e<10> to a bell-crank e<11>. A lug e<12> on this part engages a spring catch i<1> and moves it against the spring i<3>, whereupon the lever i<2> is released and is rocked counterclockwise by the spring i<4> to release the machine. A notch i<5> on this lever snaps over the lug e<12> and locks the detent plate h<1> and linkage. At the end of the operation, the cam f<7> rocks the lever i<2> against the spring i' through the linkage f<8>, f<10>, f<11>, the spring h<3> returning the detent plate and lever e", and the spring i<4> returning the lever i<2> to lock the machine. An error-correcting key k<1>, Fig. 4, acts through the lever k' to rock the arms f<2> and release the keys should no key in the special key-bank have been depressed.
