By 1914, the Cincinnati Iron & Steel Co. had introduced the "Cisco" line of engine lathes; "CISCO" was an acronym for the company's name. Cisco Machine Tool Co. was formed in 1915 as a subsidiary of Cincinnati Iron & Steel Co.; Cisco's first act was to acquire the premises of the defunct lathe maker Von Wyck Machine Tool Co. Cisco did not acquire the rights to the Von Wyck line of lathes; those rights were acquired by Kern Machine Tool Co.

Cisco continued to make the "Cisco" line of engine lathes, and then added radial drills, polishing machines and tapping machines to the product line. The company seems to have disappeared in the economic turmoil of the early 1930s.

  Enlarging Business
  The Cincinnati Iron and Steel Co. have changed their organization and are now known as the Cisco Machine Tool Co. The company have just lately erected a new building which gives them machine working space of two floors 64 x 230, this being exclusive of offices, warehouses, show rooms, shipping rooms and storage rooms which are in separate buildings. This building is equipped with all modern facilities, cranes, runways and every possible contrivance for the comfort of the workmen, while they have also installed considerable new machinery, including a 62 x 48 x 28 planer, a 3½-foot boring mill, 4-foot radial drill, two new milling machines, new keyseaters, arbor presses, upright drills and lathes, so as to increase production. The idea will be to double the number of men that are employed, and to keep up to its present quality the Cisco lathe.
