Abstract

310,362. Rheinische Metallwaarenund Maschinenfabrik S÷mmerda Akt.-Ges. April 24, 1928, [Convention date]. Addition to 301,312. Multiplying-apparatus; statistical-apparatus.- The number of key-controlling magnets in the calculating-machine connected with a card-perforating and reading apparatus as described in the parent Specification, is reduced by providing the multiplier keys only, with the controlling magnets. Thus as shown in the Figure the staggered magnets 5 of the multiplier keys 4 serving also as machine release keys are connected with the brushes and by setting up on the multiplicand keys a constant factor such as a price, a series of multiplications may be performed by feeding the perforated cards in succession under the brushes.
