Storage Battery Not in Competition at Buffalo"
Western Electrician, v. 29, no. 5 (Aug. 3, 1901) p. 71. Reproduced
here in full.]
Edison storage battery has been withdrawn from competition with
other batteries at the Pan-American Exposition. This is understood
to be because Mr. Edison is not yet quite prepared to give to the
world and the jury of awards all of what are now secrets of the
laboratory in connection with the battery.
exhibited is of one-eighth horsepower, 100 ampere-hours and weighs
5 ¾ pounds. The width of the cell is five inches, depth,
1 ½ inches, and the height 12 inches from base to terminals.
The charging rate is 1.8 volts. The cell is of steel, nickel-plated.
The insulation is perforated hard rubber, 0.64 inch thick, and the
plate complete is 0.1 of an inch thick. The battery has eight plates
or grids, each containing 24 pockets. The pockets containing the
compound are 0.003 of an inch deep and of crucible steel, perforated,
and nickel-plated. The negative plate is of nickel and the positive
of iron. The battery on exhibition has no alkaline solution. The
fluid is not an element of the battery, it being used simply as
a conductor. In the regular construction of the batteries, 60 plates
will constitute one horse-power, each plate weighing one pound.
W. H. Markgraf,
manager of the exhibit department of the Edison Manufacturing company
at the Pan-American Exposition, has this to say of the battery exhibit:
'In forwarding the parts of the battery now on exhibition at Buffalo,
it was not Mr. Edison's intention that the same should be entered
competitively against the other type of storage batteries, inasmuch
as we are not in position at this time to show it working practically.
We hope to be able to send up some of these batteries complete,
so as to put them in practical operation, and to show their superiority
over anything of the kind now on the market. It is still the company's
intention to make such an exhibit at the Pan-American before the
closing of the exposition.'
people stop at the Edison booth each day to look at this latest
invention in the storage-battery line. The battery is given a prominent
position on a table, and is protected by a glass case. Manager Markgraf
and his assistants are ever ready to explain all its features, and
it is evident that the people turn from the Edison booth amazed
at the possibilities in store for this new battery. The Edison space
is one of the best located in the Electricity building, and frequently
its three open sides are surrounded by visitors listening to the
music of the phonographs while inspecting other features of the
Thomas A. Edison
is sojourning at Chautauqua, but from time to time will run up to
the exposition to enjoy its beauties."
