Description

This notebook is a continuation of N-15-08-02.2. It was used by Absalom M. Kennedy during September-October 1915 as a daily record of experiments and tests with phonograph recorders and reproducer parts. The daily record is continued in N-15-10-21. The tests involve various recording machine parts and instruments, as well as variations in the positions of voices, instruments, recording horns, and cow-hair reflecting screens. Some of the tests relate to cylinder recorders. Kennedy\'s notes also describe other projects, such as his work for Miller Reese Hutchison on a wireless telephone system and the preparation of a two-minute recording of Hutchison for the Panama Pacific International Exposition in San Francisco. There are also references to setting up experiments at the Brooklyn Navy Yard in connection with Edison\'s work on the Naval Consulting Board. Other individuals involved in the phonograph experiments include E. Rowland Dawson, Clarence B. Hayes, William F. Nehr, R. H. Simpson, and George J. Werner. Some of the work was done on orders from Hutchison or Charles Edison. Other experiments were based on Edison\'s direct instructions and used recording horns designed by him. Two pages of comments and instructions by Edison have been inserted into the book. The front cover is labeled \"Recording Experiments Book #5 From Sept. 17, 1915 To Oct 21, 1915.\"" The pages are unnumbered, and several pages have been removed from the book. Approximately 110 pages have been used."
