THOMAS A. EDISON - AUTOGRAPH ENDORSEMENT SIGNED CIRCA 1925 CO-SIGNED BY: WILLIAM A. HARDY - HFSID 87917
THOMAS ALVA EDISON, CO-SIGNED BY: WILLIAM A. HARDY
Edison and one of his patent attorneys exchanged this signed and dated correspondence over a patent for making storage battery plates in 1925, which they thought might be related to a process developed by Edison. Includes a copy of the 1925 patent in question, by Raymond C. Benner and John H. Fink
Autograph endorsement signed:
"Return to Hardy/E"
on page 1 and
"Hardy"
on page 2 in pencil by Edison and
"W. A. H."
on page 2 by Hardy. First page is 5x8 lined paper accompanied by one-page 8½x11 letter from Hardy to Edison
dated May 22, 1925
, one page 8x10½ letter from Milans & Milans law office
dated May 15, 1925
and 8 pages of patent documents for Patent No. 1,536,064 from Raymond C. Benner and John H. Fink,
Process of Making Storage-Battery Plates
,
dated May 5, 1925.
There
was apparently some question as to whether this patent, for a process for making storage battery plates, was similar to the process for making elements in the Ford starter cell, which Edison developed in 1912 for his friend Henry Ford but which proved to have too low a voltage for starting an automobile.
HARDY
was most probably one of Edison's patent attorneys.
EDISON had incorporated the Edison Storage Battery Company in May 1901, successfully conducting tests of electric vehicles equipped with his storage battery the following year.
In 1903, Edison initiated production of his "E" type alkaline storage battery, but suspended manufacture of the battery in 1904 to investigate the loss of electrical capacity and leaking cans. In 1905, he began experimenting with perforated tubes holding nickel flake as a positive electrode for his batteries and sought information regarding sources of cobalt ore for possible use in the batteries (Edison dropped idea of using cobalt in 1907). In 1908, Edison took control of the Lansden Company, a manufacturer of electric vehicles using Edison storage batteries. The following year, the prolific inventor began production of his new "A" type alkaline storage batteries.
In 1910, Edison's storage batteries figured prominently in several technological advances: the first streetcar powered by an Edison storage battery began operation in New York City, Edison was asked to develop storage batteries for use in submarines (he would later deny that a 1916 explosion on an E-2 submarine resulted from the use of his batteries) and two electrical vehicles powered by Edison batteries set off on a promotional tour from New York City to the summit of Mt. Washington in New Hampshire.
The company merged with Thomas A. Edison, Inc. in 1932. Lightly toned and creased. Staple and binder holes and tears in upper right corner. Staple holes on left edge. Rust stains on left-hand edges. Paperclip impression on top edge of first page. Otherwise, fine condition.
