Elmer Sperry's files on the compound diesel engine and the electric transmission include a number of blueprints and patent diagrams describing his diesel engine and proposed electronic transmission. During the 1920s Sperry collaborated closely with H. C. Snow, an engineer with the Velie Motors Corporation of Moline, Illinois, and the collection includes a complete file of their letters. These records show that in spite of their efforts the diesel project was both a technological and financial failure. Sperry could not develop a working model nor could he raise the capital required to finance research and development in this area. For a while Ford Motor Company, Standard Oil, Baldwin Locomotive Works, and the Illinois Central Railroad expressed interest in Sperry's work but, when research and development did not proceed as rapidly as expected, they quickly withdrew their support.
The Joseph D. Lovell Locomotive Rosters constitute a partial roster of Pennsylvania Railroad steam, electric and early diesel locomotives to 1946. The collection also contains seven small ledgers listing the production of not only the Juniata Shops, but also the earlier Altoona Machine Shops (1866-1904) and locomotives purchased from outside builders, principally the Baldwin Locomotive Works. His lists include rosters for both the Pennsylvania Railroad proper and its predecessor lines.
There is also a folder containing copies of letters and notes by Robert B. Watson documenting the provenance of the records.
