page_text: LETTERS PATENT to George William Bremner, of 38, Fenchurch Street, in
the City of London, for an Invention of "AN IMPROVED PROCESS AND
TREATMENT OF SUBSTANCES FOR THE MANUFACTURE OF AN ADHESIVE OR
ITLE"
PROVISIONAL SPECIFICATION left by the said George William Bremner
at the Office of the Commissioners of Patents on the 19th September
1881.
GEORGE WILLIAM BREMNER, of 38, Fenchurch Street, in the City of London,
"AN IMPROVED PROCESS AND TREATMENT OF SUBSTANCES FOR THE MANUFACTURE
OF AN ADHESIVE OR GLUE,"
This Invention relates to improvements in the manufacture of a glutinous
substance or substances known as syrup of biphosphate of alumina, crystaline, or
mineral gum, or syrup obtained from a mineral known as bauxite, to render those
substances one, all, or any of them, together or otherwise, mixed or unmixed,
into a substance of a more fibrous nature similar to glue; and of very great tenacity
and adhesiveness.
For the purposes of my Invention 1 take the substances above named separately
or together, as may be found in practice to be most serviceable for the purpose
above named, and I admix with it or them, one, all, or either, refuse ivory or refuse
bone dust, dry or green bone, dissolved bone, or bone phosphate, or dissolved horn,
or whale bone, or hair and blood, the hair being previously dissolved by the
ordinary process, and I add dissolved animal legamentous tissue or not as may be
found necessary for the kind of material at the time under manufacture, and I
boil for some hours consecutively the admixture as above in a steam jacket,
cylinder, or pan, keeping the admixture constantly stirred during the boiling until
I find the whole mass has become one associated body; I then add or not refuse
asbestos dust in a small quantity, thoroughly admixing it with the product under
treatment.
The product obtained can then be evaporated down to any density required.

GEORGE WILLIAM BREMNER, of 38, Fenchurch Street, in the City of London.
"AN IMPROVED PROCESS AND TREATMENT OF SUBSTANCES FOR THE MANUFACTURE
OF AN ADHESIVE OR GLUE."
This Invention relates to certain processes for the treatment of substance or
substances known as syrup of biphosphate of alumina, crystaline, or nineral guni,
or a syrup obtained from bauxite, to render those substances when admixed as
described below into a strong adhesive or glue.
For the purpose of my Invention I take any one of the above substances, or an
admixture of them, as may be found in practice to produce the strongest product,
and I place it or them into a jacket, pan, or cylinder lined with lead and heated by
steam, and I admix with it or them refined alumina, agitating and heating the
product at the same time, keeping it by preference under boiling point. I continue
the supply of alumina so long as the liquor will absorb and take it up; the effect of
this absorption is the product becomes more glutinous and the excess of acid is
absorbed and in a great measure neutralised; I then add in such quantity as may
be requisite to form a strong body dissolved ivory, or horn, or bone, or whale bone,
or bone phosphate, or hair, or any ligamentuous tissue, either separately or admixed
to the liquor under treatment, and I add or not 1 per cent. more or less of blood.
I then simmer (not boil) the mass for several hours and keep it constantly agitated
until the admixture has become one associated body of a very glutinous and
adhesive character, similar to glue or down to a similar density, but I prefer to
allow it to remain in a semi-liquid state in order that the fermentation that
-ensuos-may-more-readily take place as the admixture does not decompose in a
liquid state or loose its adhesive power as ordinary glue would.
It will be readily understood that the glutinous substances, syrup of biphosphate
of alumina, crystaline, or mineral gum, or a syrup obtained from bauxite, as above
described, may be used as obtained in their simple form without the addition
of more alumina, but I prefer to carry my Invention into practice as above set
forth.
Although I describe in the first part of this Specification the mode of manu-
facture, I do not strictly confine myself to it, as the multifarous uses this product |
can be applied to in the arts and manufacturers of this and other countries must of
necessity show that at times some deviation is requisite in order to adapt it for
various purposes to which it may be applied; and the better to illustrate this it
will be readily seen that this product when admixed with cellulose, or wood fibre,
or paper, with or without gypsum or plaster of Paris and asbestos in powder, and
the whole mass boiled, a very strong material will be obtained, as hard as stone
and of a very tough nature, capable of being converted into large slabs like marble
(coloured), and also for architectural ornamentation for inside work of houses, in
addition to which it may be used for very many various purposes..
Having now described the nature of my said Invention and in what manner the
same is to be performed, I declare that I claim,-
The process and treatment of the ingredients before mentioned in the manner

page_text: set forth for the manufacture of an adhesive or glue and for the production of solid
articles as described.
In witness whereof, I, the said George William Bremner, have hereunto
set my hand and seal, this Seventeenth day of March, in the year of our
Lord One thousand eight hundred and eighty two.
