Improvements; in the Manufacture of Liquid Cement or Gum.
We, EDWARD MARTIN KNIGHT of 148, Cheapside London, Machinery Agent, and
AMOS HERBERT HOBSON of 5 Agar Street, Strand, London Chemist do hereby
declare the nature of our invention for IMPROVEMENTS IN THE MANUFACTURE OF
LIQUID CEMENT OR GUM to be as follows :-
--
The improved cement is manufactured by the combination of glue, or other
gelatinous substance and any alkaline substance such as potash, soda, or borax, aided
by the action of heat.
In the preparation of cement or gum according to this our invention we employ the
following ingredients in quantities and proportions about as follows.
For each gallon of cement or gum required, about one and a half gallons of water
two pounds of glue or more according to the strength required, four ounces of borax,
and two ounces of soda carbonate or an equivalent quantity of any other alkali or
alkaline substance.
In the process of manufacture, first, dissolve the ingredients in water by the aid of
heat and afterwards keep the ingredients at a temperature below boiling point; for
say-five to six hours or such other time as may be required.
The effect of the continued application of heat is to render the solution permanently
liquid at all ordinary temperatures.
This liquid is allowed to stand and then the sediment is separated from the super-
natant liquid which is afterwards concentrated by evaporation to the required
consistency.

Improvements in the Manufacture of Liquid Cement or Gum.
We, EDWARD MARTIN KNIGHT of 148 Cheapside, London, Machinery Agent, and
AMOS HERBERT HOBSON of 5 Agar Street Strand, London, Chemist, 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 improved cement is manufactured by the combination of glue, or other
gelatinous substance and any alkaline substance such as potash soda or borax, and
by the action of heat.
In the preparation of cement according to this our invention we employ the
following ingredients in quantities and proportions as follows.
For each gallon of cement or gum required, about one and a half gallon of water,
three pounds of glue or more according to the strength required, four ounces of borax,
and two ounces of soda or an equivalent quantity of any other alkali or alkaline
substance.
In the process of manufacture, first dissolve the ingredients in water by the aid of
heat, and afterwards keep the ingredients at a temperature a few degrees below boiling
point for say-five to six hours or such other time as may be required.
The effect of the continued application of heat is to render the solution permanently
liquid at all ordinary temperatures.
This liquid is allowed to stand and then the sediment is separated from the
supernatant liquid which is afterwards concentrated by evaporation to the required
consistency.
Such being the nature and object of our said Invention the following is a complete
description of same.
The improved cement or gum is manufactured by the combination of glue, or other
gelatinous substance, such as gelatine and any alkaline substance, such as potash,
soda, or borax, by means of the action of heat.
In the preparation of cement according to this our invention we employ the
following ingredients in quantities and proportions about as follows.
For each gallon of cement or gum required, about one and a half gallon of water,
two pounds of glue or gelatine or more according to the strength required, four
ounces of borax, and two ounces of carbonate of soda, an equivalent quantity of any
other alkali, or alkaline substance, such as carbonate of potash, bi-carbonate of soda,
or of potash, caustic soda, or caustic potash, or the same quantity of soda or other
equivalents, such as carbonate of potash, bi-carbonate of soda or potash &c. in com-
bination with any other antiseptic substance instead of borax, such as salicylic acid, or
the same quantity of borax, or a greater quantity of borax according to the quality of
the glue or other gelatinous substance may be used instead of the combination of borax
and soda or other equivalent.

page_text: In the process of manufacture first dissolve the ingredients in water by the aid of
heat, and afterwards keep the ingredients at a temperature a little below boiling
point for say-five to six hours or such other time as may be required.
The effect of the continued application of heat to this combination is to render the
gelatinous solution permanently liquid at all ordinary temperatures.
This liquid is then filtered or allowed to stand and then the sediment separates.
The supernatent liquids removed from the sediment by syphon or otherwise, which are
afterwards concentrated by evaporation to the required consistency.
Having now particularly described and ascertained the nature of our said Invention,
and what manner the same is to be performed, we declare that what we claim is :-
The improved manufacture of liquid cement or gum by means of the combination of
ingredients, and the operations as heroin fully set forth.
