PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Battery Cells or Vessels to
Contain Acids or other Chemicals.
DAVID MARC HAWES 40 King Street Cheapside E.C. Mechanical Engineer
do hereby declare the nature of this invention to be as follows:-
My improvements consist in constructing boxes, cells, or other vessels to contain
acids or other chemicals, more especially applicable to electric batteries.
We build up a box or other vessel of asbestos or similar material impregnated
either before or after manufacture or coated on either one or both sides with liquid
celluloid. The joints of this box or vessel may be made by means of passing a hot
iron over them and thereby uniting the over-lapping surfaces by means of the
liquid celluloid which acts as a cement. The asbestos or other material may also
be mixed with liquid celluloid to form a pulp and the pulp be formed by dies into
any required shape.

Improvements in the Manufacture of Battery Cells or Vessels to
Contain Acids or other Chemicals.
I, DAVID MARC HAWES, of 40 King Street, Cheapside, London, do hereby
declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
My improvement consists in constructing boxes cells or other vessels to contain
acids or other chemicals more especially applicable to electric batteries.
We build up a box or other vessel of asbestos impregnated either before or after
manufacture or coated on either one or both sides with liquid celluloid. The joints
of this box or vessel may be made by means of the liquid which acts as a cement.
The asbestos may also be mixed with liquid celluloid to form a pulp and the pulp
be formed by dies into any required shape.
In carrying my invention into practice according to the first of the methods
above referred to I prefer to proceed as follows:-I take an asbestos fabric
preferably a woven fabric but asbestos paper or cardboard may be employed.
I coat or impregnate the fabric preferably on both sides with liquid celluloid by
the means described in the Specification of Annison's Patent No. 19710 in the
year 1891 I cut the fabric so coated or impregnated into pieces suitable to form
the sides, ends, and bottom of the box cell or vessel I desire to produce and I build
these pieces together using liquid celluloid as a cement.
According to the other method above mentioned I mix liquid celluloid with
powdered asbestos or asbestos fibre in the proportion of about one part of the
D

page_text: former to two of the latter by weight. In this way I produce a stiff dough like
mass which I mould in dies to the shape of the box cell or vessel I desire to
produce.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The manufacture of boxes cells and vessels to contain acids or other chemicals,
from asbestos fabric coated or impregnated with celluloid and jointed together in
the manner described.
2. The manufacture of boxes cells and vessels to contain acids or other chemicals
from a pulp consisting of asbestos and liquid celluloid moulded by dyes to the
shape of the box, cell or vessel required.
