Patent GB-783875-A (GB)
Abstract: 783,875. Calculating-apparatus. BURROUGHS CORPORATION. Oct. 1., 1954, No. 16500/55. Divided out of 783,869. Class 106(1). A spring for returning the pin-carriage of a ten-key calculating machine is normally disconnected from the carriage and a coupling is effective, during cyclic operation, to connect the spring to the carriage until the carriage has returned. The invention is applied to the machine described in Specification 783,869, the carriage being advanced stepwise during setting by the spring means described in Specification 766,127. During this stepwise movement of the carriage, a rack 139 connected therewith moves leftwardly and rocks a lever 431 pivoted at 432 to withdraw a coupling stud 438 from an arm 436 of a coupling lever 435. A pair of return springs 440A, 440B interconnect a pair of levers 441A, 441B pivoted at 439C, the lever 441A pivotally supporting the coupling lever 435, whilst the lever 441B bears leftwardly against a stud 442 on a cyclic operating member R under the action of a spring 435A applied to lever 435. During cyclic operation, the forward movement of member R results in leftward movement of the levers 441A, 441B and 435 so that the arm 436 overtakes the stud 438, an inclined blade 437 overlying the lever 431 enabling the arm to ride over and ahead of the stud. Upon return of the operating member R, the lever 441B also is returned but the lever 441A and coupling lever 435 are arrested by coupling engagement of the arm 436 against the stud 438, the rack 139 being held by a locking pawl (not shown) engaged at the commencement of the cycle. The continued movement of the lever 441B thereupon stretches the springs 440A and 440B so that when the pawl is tripped and the rack 139 released towards the end of the cycle, the lever 435 is restored by these springs and, through its coupling arm 436 and the stud 438, restores the rack 139 and pin carriage. The lever 435 is finally rocked upwardly and clear of the now stationary stud 438, by engagement of a lower arm with an abutment 4391, so as to revert to its initial position shown. Error correction. The carriage can also be returned in order to cancel an incorrect setting, by manual operation of an error key. This key is operable directly on the lever 441A through a lever 429 and a link 434 having a one-way pin and slot coupling.
