These ninety-four notebooks were used by Walter N. Archer, James Byrne, William J. Carson, John V. Miller, Harold H. Smith, and numerous other laboratory employees during the years 1910-1929. The books are described and listed in the following order: (1) Silver Lake/Short Tube/Ni(OH)2 Tests (38 books); (2) "Before and After" Physical Appearance Tests (5 books); (3) Microscope Tests (39 books); (4) "In and Out" Tests (9 books); (5) Metal Parts Books (3 books).
These thirty-eight notebooks were used during the years 1914-1929 by Walter N. Archer, Frank Christian, C. Emerson, Charles F. (Frank) Hunter, B. Laird, John V. Miller, Harold H. Smith, J. J. Voss, and other, unidentified experimenters. The books contain data on consecutive charge/discharge runs for various storage battery cells. The individual entries in some books provide data on the assembly of cells for specific (regular) tubes "loaded," including information about various hydrates and flakes tested in tubes. The tubes range from early experimental runs to later runs that were more closely watched. Some books detail the subsequent construction and production of the tubes. E-numbers refer to experimental pockets, and R-numbers refer to regular pockets.
Some books, such as N-14-06-11.1 and N-14-06-18.2, indicate limited oversight by Edison, with entries bearing his initials and the inscription "CO" for "cut out" of certain cells. Work in other books was done under the direction of Archer or Miller. Some notebooks indicate that they were used in Archer's Tube Testing Dept. at the Edison Storage Battery Co., while others were used in the Research Dept.
These five notebooks were used during the period June1914-June1919 by James Byrne. They contain a record of tube inspections before and after testing. Included is information about tube numbers, dates of inspections, and physical conditions such as cracked tops and bottoms, loose rings, seams, scratches on plating due to putting on rings, and perforations. The first four books were used consecutively, while the fifth book covers the entire period 1914-1919.
These thirty-nine notebooks, which cover the period April 1910-July 1921, were used to record data on positive electrode tubes produced by the Edison Storage Battery Co. Much of the data was probably entered by female employees, including M. Hoyle, Julia Kothes, and E. Malone, who worked under the supervision of Walter N. Archer in his role as inspector from 1913 to 1919. Most of the books bear labels by Archer indicating their origin in "Tube Testing Department 24-2" of ESBCo, while notations on a few of the later notebooks indicate their origin in the "Research Department." There are three sets of books. The first deals with microscope tests of 1/4" tubes (34 books), the second with 3/16" tubes (4 books), and the third with 1/8" tubes (1 book). The data in the books was used to calculate averages, including "average dumps per tube tested, "average per cent of good contacts in center," and "average tubes tested [with] lines in center not in contact." The results were reported to Edison, Robert A. Bachman, and other company executives.
These nine notebooks were used during the years 1912-1916 by William J. Carson, Joseph Hesse, and other, unidentified experimenters. They contain tabulated data on production tests of storage battery tubes. Included is information on cell numbers, numbers produced, tube types (short, long, Silver Lake iron, etc.), and "out" and "in" cycles. Some of the books contain summary data at the front or back.
These three notebooks were used by Walter N. Archer and other, unidentified experimenters during the period October 1909-March 1918. They report on loading weights for storage battery tubes and include daily entries in several hands that give the amounts and weights of right tubes, left tubes, rings, top caps, and bottom caps.
