IMPROVEMENTS IN THE MANUFACTURE OF ELECTRICAL BATTERIES
Year: 1885

page_text: I, LEVI PARSONS MERRIAM of 124, High Street, Homerton in the County of
Middlesex, Manufacturer do hereby declare the nature of my invention for
"IMPROVEMENTS IN THE MANUFACTURE OF ELECTRICAL BATTERIES," to be as
follows:-
My invention relates to electrical batteries whether primary or secondary and
has for. object the prevention of leakage of the battery solution or liquid at the
joints of the cells and troughs.
For this purpose I form these joints by means of xylonite or other pyroxylin
compound which is not affected by ordinary battery solutions or liquids.
In carrying out my invention I either make the pieces of which the cells and
troughs are to be formed entirely of a pyroxylin compound, or of wood or other
suitable material covered or coated with a pyroxylin compound either over their
whole surface or only at such parts as have to be united to adjoining pieces; and
I unite these pyroxylin pieces or pyroxylin covered pieces by means of a solution
of pyroxylin compound applied to the parts to be united at the time when it is
wished to effect the union. This pyroxylin solution temporarily dissolves or softens
the pyroxylin surfaces to which it is applied and when it and the said surfaces
have hardened or set, suitable pressure being applied, the union or marriage of the
surfaces is complete.
Or, instead of uniting the pyroxylin pieces or pyroxylin covered pieces by a
solution as above described I employ for the pieces freshly made, that is to say
unset, material. These pieces when brought together and held under pressure will
unite as they set or harden.

what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-

dipping them therein, or by means of a brush or otherwise."
Or, instead of uniting the pyroxylin pieces or pyroxylin covered pieces by a
solution as above described I employ for the pieces freshly made, that is to say,
unset material. These pieces when brought together and held under pressure will
unite as they set or harden.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim, in respect of the manufacture of electrical batteries, is
1. Forming the joints of electrical battery cells and of electrical battery troughs
by means of a pyroxylin compound as and for the purpose set forth.
2. Electrical battery cells and electrical battery troughs made of, or covered,
or coated with a pyroxylin compound at the joints and united at the said joints
by means of a pyroxylin compound or by the pieces being brought together and
held under pressure while fresh or unset, substantially in the manner and for the
purpose described.
