PROVISIONAL SPECIFICATION.
An Improved Manufacture of Liquid Waterproof Glue.
I, WILLIAM GEORGE RICHARDSON, of 36 Leamington Street, Bradford, Yorkshire;
Agent, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to manufacture a liquid glue, specially adapted for,
domestic purposes, but such glue may with equal advantage be used for commercial
purposes. In preparing the liquid glue, I dissolve gum shellac in naptha, spirits of
wine, or other like solvents. There may also be used a suitable proportion of silver
grey, ol. recini, or other suitable oil, with or without the addition of ol. myrbane.
The above ingredients when dissolved and freely mixed together form a liquid glue
thoroughly waterproof, so that articles joined together by the above form of glue will
not become loose by damp or water, as such said glue is not soluble by either water or
heat.

COMPLETE SPECIFICATION.
An Improved Manufacture of Liquid Waterproof Glue.
1, WILLIAM GEORGE RICHARDSON, of 36 Leamington Street, Bradford, Yorkshire.
Agent, 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:-
The object of my invention is to manufacture a liquid glue specially adapted for
domestic purposes, but such glue may with equal advantage be used for all and every
purpose where glue can be used, and on account of its waterproof qualities is
particularly adapted for use in making any joint that is exposed to the action of water.
The materials to be joined may be leather, wood, metal, stone, china, earthenware,
cloth, paper, ivory, bone, cork, gutta-percha, rubber, meerschaum and the like either
in combination or otherwise and for the purpose of covering electric or other wires for
insulating or other purpose and for lining battery tanks and the like. In preparing
the glue, I dissolve gum shellac, white, orange or other color in naphtha, spirits of
wine, or other suitable solvent, with a proportion of ol. recine, ol. myrbane or other
suitable vegetable oil with a proportion of Stockholm, or other good tar, and boracic
acid and any suitable dye soluable in spirits, the color of which depends upon the
work for which the glue is required.
The above ingredients when freely mixed together form a liquid glue thoroughly
waterproof, so that articles joined together by the same will not become loose by damp
or water as such said solid ingredients are not soluble individually or collectively in
water.
The following proportions of the ingredients have been found very suitable in
practice, but I do not limit myself to these, and only mention them by way of
example.
