Director of the Universal Inventors and Patentees Financial Company
Limited 30 Finsbury Pavement London E.C. for an Invention of "A NEW OR
IMPROVED PROCESS FOR PREPARING FLUID GLUE FROM FISH, WHALE, AND
OTHER SEA ANIMALS A communication to him from abroad by Carl Adolf
Sahlström, Engineer, of Jönköping, in the kingdom of Sweden.

PROVISIONAL SPECIFICATION left by the said Lorentz Albert Groth at
the Office of the Commissioners of Patents on the 5th December 1882.
LORENTZ ALBERT GROTH, K.G.V. Civil Engineer and Managing Director of The
Universal Inventors and Patentees Financial Company Limited, 30 Finsbury.
Pavement London, E.C. "A NEW OR IMPROVED PROCESS FOR PREPARING FLUID
GLUE FROM FISH, WHALE, AND OTHER SEA ANIMALS A communication to me
from abroad by Carl Adolf Sahlström, Engineer, of Jönköping in the Kingdom of
Sweden.
"
The object of this invention is the production from fish, whale, and other sea
animals of a fluid glue possessing great tenacity and adhesive qualities.
The fish or portions thereof are soaked in cold water until all the albumen, salts,
and other matters capable of being so extracted are separated therefrom, after
which the superfluous water is removed by pressure or otherwise. :
The mass thus obtained is then disintegrated by suitable mechanical means and;
kept for a period of from one to ten hours in hot water the temperature of which
should not exceed 80° Centigrade.
For every 100 parts of the above mentioned disintegrated mass from 150 to 500
parts of water are required with which is also mixed from 1 to 20 parts of acid of
vinegar.
-
The fluid portion of this mixture is afterwards separated by any suitable means
and is then filtered, and evaporated in vacuo or open pans until the desired degree
of consistency is obtained, and is then finally mixed with from one half to five per
cent of sugar.
The mass remaining after the above mentioned separation of the fluid portion is
boiled under a pressure of from 3 to 6 atmospheres and from it is obtained a
second quality glue which is treated in the same manner as above stated.

The object of this invention is the production from fish, whale and other sea
animals of a fluid glue possessing great tenacity and adhesive qualities.
The fish or portions thereof are soaked in cold water until all the albumen, salts,
and other matters capable of being so extracted are separated therefrom, after the
superfluous water is removed by pressure, centrifugal machinery or otherwise
The mass thus obtained is then disintegrated by suitable mechanical means and
kept for a period of from one to ten hours in hot water the temperature of which
should not exceed 80° centigrade. For every 100 parts of the above mentioned
disintegrated mass from 150 to 500 parts of water are required with which is
also mixed from 1 to 20 parts of acid of vinegar
The fluid portion of this mixture is afterwards separated by any suitable means
and is then filtered and evaporated in vacuo or open pans until the desired degree
of consistency is attained and is then finally mixed with from one half to 5 per
cent of sugar.
The mass remaining after the above mentioned separation of the fluid portion
is boiled under a pressure of from 3 to 6 atmospheres and froin it is obtained a
second quality glue which is treated in the same manner as above stated
Glue prepared in the manner above described is freed froin all noxious salts and'
therefore possesses unusual adhering power.
Having now described the nature of the said invention and the manner in which
the same is to be carried into effect I would have it understood that what I claim
as the invention to be secured by the within in part recited Letters Patent is
Producing glue from fish, whales, and other sea animals or parts of the same by
soaking such materials in warm water mixed with acid of vinegar after they have
liberated from all the albumen, salts, and other extractive matter, substantially
as herein described.
In witness whereof I the said Lorentz Albert Groth have hereunto set my
hand and seal this fourth day of June in the year of Our Lord One
thousand eight hundred and eighty three.
