invention relates to computing machines and more particularly to such machines whose operations involve the obtaining and the accumulation, additively or subtractively, of products; and it has for its principal object to provide improved multiplying mechanism for such machines. The invention relates to that class of computing machines that yield a product by true multiplying mechanism as distinguished from that class of machine whose mechanism is essentially that of an adding machine and in which when a number is multiplied by 3, for example, the number is set up and the machine operated 3 times.
