Description

[The first paragraph of this note covers all of the Unbound Notes and Drawings for Part I.]

The loose technical notes and drawings constituting this collection cover the years 1873-1878. They relate to a variety of subjects, including telegraphy, electric lighting and power, the electric pen and duplicating press, the telephone, and the phonograph. There are also documents pertaining to various other subjects, such as carbon rheostats, acoustic devices, the tasimeter, and the voltameter. The unbound notes and drawings are organized by year and within each year by subject. Undated notes and drawings, organized by subject, follow the dated material.

This folder contains notes and drawings signed by Edison, Charles Batchelor, Martin N. Force, George E. Carman, and John Kruesi. They relate to a variety of subjects. Many of the items pertain to the electric pen and duplicating press—a copying system developed by Edison during the summer and fall of 1875. At the end of the folder are 14 pages that were apparently removed from one tablet notebook. The first page bears a notation by William Carman identifying Alex Craig, Jr., as the probable author."
