Description
This object consists of two identical shaped steel pieces from the printer section of a Powers tabulating machine. Each carries ten pieces of type that fit into the arch of the piece. At the top is a 0, at the bottom a 9.
Powers took out patents for tabulating machines in the early 20th century. These pieces are similar but not identical to those shown in patents of 1917 and 1921, and to pieces from a Powers Accounting Machine Corporation parts catalog from 1923. They are more similar to drawings in a patent filed in 1926 by Joseph R. Merkle and assigned to Remington Rand, Inc., the successor firm to Powers Accounting Machine Company.
