History

Part of a small array of hand tools displayed in "America On The Move" - such tools were used in the inspection and repair of steam locomotives. Light repairs on steam locomotives were usually done in roundhouses at the many small locomotive terminals throughout a railroad's system; heavy repairs were done in a large, centralized repair shop serving the whole system (often referred to as the "Back Shop"). Most of these tools date from the early- to the mid-20th century, roughly 1900-1955.

The name of this unusual wrench comes from its obvious shape. The single wrench accommodated three sizes of bolt heads or nuts. It was useful only in locations on a locomotive or railroad car where there was plenty of clearance around a bolt or nut.
