Unbound. Condición: Very Good. A collection of 20 letters, memos, and ephemera pertaining to the career of a transit engineer in Philadelphia in the 1940s. All items are very good or better with some edgewear and small tears. A small archive of papers from the life and career of Samuel Lamborn, a transit engineer in Philadelphia in the 1940s. The papers contain memos, notes from meetings, and details for projects. Lamborn was a designing engineer, sometimes written as "car engineer," for the Department of City Transit in Philadelphia. His notes cover everything from what seats to use in subway cars, to "braking characteristic," and a three page essay on the use of existing "underground structures" as deciding factors for where to build subway lines. A letter from the Radel Leather Manufacturing Company reads, "Our files shows in 1938, your new subway cars were equipped with Heywood Wakefield seats, one half of which were covered with Radel Leather.It would be interesting to receive a report from you on the performance of our leather." A retained copy of a report titled "Breaking Characteristics Market-Frankford Subway-Elevated Cars" dated August 11, 1944 describes a series of tests done by Lamborn and his team on the break system of the subway cars. In 1945 Lamborn was offered a position as a Mechanical Engineer and Consultant for the Research and Development Division at the Pentagon which he declined in a letter seen here. A modest but interesting collection of ephemera documenting the career of a car engineer in Philadelphia in the 1940s.
