Scope and Contents
While some of the MACHINERY RECORDS, 1903-1954, relate to the engines and boilers used to keep the factory running, most deal with the machines used to turn out finished ivory keys, piano keyboards, and piano actions. These take the form of a series of oversize blueprint drawings on each machine. The drawings are arranged according to their original order of placement in several different folios of drawings. Thus, drawings for the same machine are sometimes found in different folders within this subseries usually indicating later modifications to the machine. These drawings were selected by a historian knowledgeable about machinery and manufacturing processes during the initial visit to the Pratt, Read site. They were chosen for their emphasis on the specialized processes involved in working with ivory and the production of pianos. Drawings for more general purpose machines were not selected for this collection. The drawings of specialized machines, dating from 1903 1934, are located in ten oversized folders in two map case drawers.
Collection Restrictions
Collection open for research on site by appointment. Unprotected photographs must be handled with gloves.
