Patent GB-337607-A (GB)
Abstract: 337,607. Schubert, E. March 4, 1929, [Convention date]. Multiplying and dividing apparatus; zeroizing-mechanism.-In a calculating-machine of the cam-disc and pinwheel type, the amount on the totalizer may be transferred to the pin-wheels by the single rotation of a shaft, devices thereon effecting in succession the zeroizing of the cam-discs, the displacement of the carriage or other means for coupling up the counter with the cam-discs, and finally the zeroizing of the counter and consequent transference of its total to the discs and pin-wheels. The shaft 1 during the first part of its rotation zeroizes the cam-discs 4 by means of the toothed sector 5 and the intermediate gearing shown. During the next part of the rotation, a cam 9, Fig. 6, rocks a comb plate 10 to raise the carriage-position key 8, and another cam 11, Fig. 7, effects the necessary slight displacement of the carriage by means of the lever 12, so as to couple the totalizer with the cam discs. Instead of shifting the carriage, a set of intermediate pinions additional to the usual ones 15 may be moved into coupling position. During the remainder of the rotation of the shaft 1 a segment 16, Fig. 8, operates the zeroizing-spindle 21 through gearing 17 - - 20. It will be noted that the above operations take place whatever the denominational position occupied by the carriage, on account of the form given to the members 10, 18. The shaft 1 is rotated by a motor when a key R, Fig. 7, is depressed to shift a bar 22 to close contacts 24. If it is desired to zeroize the counters without transferring the product to the setting-mechanism, a key O may be depressed to operate the bar 22 and at the same time to shift the cams 9, 11 axially to render them ineffective.
