PROVISIONAL SPECIFICATION.
An Improved Glue or Cement.
I, GEORGE ROTHEL, of 25 Kenmont Terrace, College Park, Kensal Green, in the
County of Middlesex, Parquet-Flooring Manufacturer, do hereby declare the nature
of this invention to be as follows:-
My Invention relates to an improved waterproof glue or composition, possessing
firm hard and elastic properties, for affixing parquet-flooring, dados, and other
decorative wood-work, floor and wall tiles, etc., to wood, iron, glass, concrete, or other
surfaces.
The glue is composed of the following ingredients in about the proportions
mentioned, which give good results, although I do not bind myself absolutely
thereto :
Scotch glue
Rosin
Gutta-percha
Caoutchouc
Wood ashes
Red lead
Bisulphide of Carbon
Zinc ash
6 lbs.
2
"
2 ozs.
1 oz.
2 ozs.
4
"
1 oz.
2 ozs.
The composition is prepared in the following manner: The glue is first boiled
separately, after which the rosin is dissolved in bisulphide of carbon, with the aid of
heat, and added to the glue. The gutta-percha is then reduced to a jelly by means of
bisulphide and the caoutchouc in like manner, after which the two are dissolved
together, by means of heat, and added to the glue and rosin, and the several ingredients
are boiled for two hours.
The red lead, wood ashes, and zinc ash which are added to the mixture serve, the
former, together with the india-rubber and gutta-percha, to render the glue water-
proof, and the two latter to keep the bisulphide of carbon disseminated throughout the
mass during the boiling and prevent its evaporation and burning. The zinc ash also
hardens the composition.
The whole mixture is then boiled for three hours, after which the glue is ready for
running into moulds to form blocks of say about five to six pounds in weight.
To use the glue, the blocks are placed over a fire in an ordinary zinc pail in order
to reduce it to a liquid state and it is then poured, while hot, on to the surface upon
which the parquet-flooring, etc., is to be laid, or the wood blocks, etc., may be dipped
in the liquid composition and then applied, the composition setting in about two
minutes.

An Improved Glue or Cement.
I, GEORGE ROTHEL, of 25 Kenmont Terrace, College Park, Kensal Green, in the
County of Middlesex, Parquet Flooring Manufacturer, 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 Invention relates to an improved glue or composition which is capable of
perfectly resisting dampness and possesses firm hard and elastic properties which may
be employed for affixing parquet flooring, dados, and other decorative wood-work,
floor and wall tiles, etc., to wood, iron, glass, concrete, or other surfaces. The glue is
composed of the following ingredients in about the proportions mentioned, which give
good results although I do not bind myself absolutely thereto:-
Scotch glue
Rosin

Gutta-percha
Caoutchouc
Wood-ashes
Red-lead
Bisulphide of Carbon
Zinc-ash

The composition is prepared in the following manner: The glue is first boiled
separately, after which the rosin is dissolved in bisulphide of carbon with the aid of
heat and added to the glue. The gutta-percha is then reduced to a jelly, by means
of bisulphide, and the caoutchouc in like manner, after which the two are dissolved
together, by means of heat and added to the glue and rosin and the several ingredients
are boiled for two hours. The red lead is then added to the mixture, and afterwards
the wood ashes and zinc ash, the former serving, together with the india-rubber and
gutta-percha, to render the glue waterproof and the two latter to keep the bisulphide
of carbon disseminated throughout the mass during the boiling and prevent its
evaporation and burning. The zinc ash also has the effect of hardening the composi-
tion. The mixture is then boiled for three hours and at same time stirred by
mechanical means, and may then be cast in moulds in the form of blocks of say, about
five to six pounds in weight.
To prepare the glue for use it is liquefied by heat and may then be poured on to
the surface upon which the parquet flooring, etc., is to be laid, or pieces of the wood
etc., may be dipped in the liquid composition and then applied, the composition setting
in about two minutes.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The manufacture of the herein described glue or cement, composed of sub-
stantially the ingredients herein referred to in about the proportions specified.
2nd. In the manufacture of a waterproof glue or cement in which gums and resins
are used, the employment, in combination with bisulphide of carbon as a solvent, of
zinc ash and of wood ashes conjointly, substantially as, and for the purposes,
specified.
Dated this 11th day of February 1890.
