American Tool Works was located at the northwest corner of Pearl Avenue and Eggleston Avenue in Cincinnati, Ohio. The streets is this area have changed much over time, with the expansion of highways in this area, but the building still stands, in the 700 block of East Pete Rose Way at the northeast corner of Eggleston Avenue. The American Tool Works was the successful bidder many times during the building of the Panama Canal (built between 1904 and 1914). American Tool Works Company was one of the largest and oldest builders of lathes, planers, shapers and radial drills in the country. The types of lathe built by ATW for use in the Canal Zone were built in various sizes from fourteen inches to forty-two inches swing. One of the principal characteristics of the “American” lathe is its patented drop bed, which gives additional swing over the nominal swing, and also permits the use of an unusually deep carriage bridge. A complete quick change gear mechanism is supplied on all sizes of American lathes. It is of the cone and tumbler type, affording forty-eight changes for screw setting and feeding. In addition to this standard range any odd thread can be secured by simply adding a special gear to a quadrant provided for this purpose View on Ohio Memory.
