[NA351-F] N-15-06-04.2 (1915)

This notebook is a continuation of N-15-03-17. It was used by Absalom M. Kennedy during June-August 1915 as a daily record of experiments and tests with phonograph recorders. The daily record is continued in N-15-08-02.2. The tests involve various recording machine parts, instruments, and positions of the recording horn. Some entries mention tests of the kinetophone, the "chronograph" and the "kinetophonograph," along with the storage battery search light. Also included are references to Kennedy's collaboration with Newman Henry Holland and an experimenter named Taylor (probably Henry A. Taylor) on an Amberola home recording machine and his work for Miller Reese Hutchison on a microphone system. Kennedy's notes also describe other projects such as the preparation of a "talking picture show" for the Commissioners of the Chinese Republic and the training of Diamond Disc demonstrators, and they document Edison's own involvement in the phonograph experiments, including his comments, suggestions, and further instructions. Other individuals involved in the work include F. C. Burt, John P. Constable, Zachariah P. Halpin, Clarence B. Hayes, Archie D. Hoffman, John J. Riley, R. H. Simpson, and George J. Werner. Some of the tests and demonstrations were done on orders from Hutchison. The front cover is labeled "Recording Experiments Book #3. From June 4, 1915. To Aug. 2, 1915. Kennedy." The pages are unnumbered. Approximately 120 pages have been used.
