Complete Specification Accepted. 12th Feb, 1889
We, EUGENE HERMITE EDWARD JAMES PATERSON and CHARLES FRIEND COOPER'
all of European Works, Pownall Road Dalston in the County of Middlesex, Engineers,
do hereby declare the nature of this invention to be as follows:-
In many voltaic batteries, especially such as are employed for electrolytic purposes,
it is desirable to have sets of plates which, while they are good conductors of
electricity, are not readily oxidisable and which at the same time should present a
very extended surface. Platinum sheets, or materials coated with platinum have been
used for this purpose, but unless these sheets or coatings are extremely thin and
therefore weak and liable to damage, the required extent of surface can only be
obtained at great expense. The object of this invention is to provide plates presenting
very large surface of platinum or analogous metal without involving great weight or
cost of the metal employed. For this purpose we draw the metal into very fine wires
and weave or braid them into a web of gauze. From this web we cut pieces of the
required size and fit each piece in a frame of insulating material casting or soldering
on to one end of the piece of gauze, lead or other suitable metal to form a conductor.
from or to all the wires of the gauze.

performed to be particularly described and ascertained in and by the following
statement :-

suitable metal to form a conductor from or to all the wires of the gauze.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we
claim is :-
The construction of plates for voltaic batteries employed for electrolytic or other
purposes, by drawing metal into fine wires weaving them into gauze and supporting
sheets of this gauze in insulating frames with a conductor cast, soldered or otherwise
metallically connected to the gauze, substantially as described.
