The object of this invention is to remove the oil or grease from animal and
vegetable substances by means which will avoid the drawbacks arising from the
use of chemicals.
It is based upon the extraordinary power possessed by infusorial earth to absorb
fluids &c and consists in mixing the oiled material viz wool horsehair woollen
fabrics &c with infusorial earth in a suitable vessel heated in any suitable manner,
10 or 20 degrees centigrade above the melting point of the oil or grease, during
which the whole is stirred to ensure the thourough cleansing of the material.
When the oil has been extracted it is spread in thin layers on a strainer and
exposed to a shower of hot water which carries away the infusorial earth leaving
the material clean and ready to be dried in any suitable manner.

"
The object of this invention is to remove the oil or grease from animal and
vegetable substances by means which will avoid the drawbacks arising from the
use of chemicals.
It is based upon the extraordinary power possessed by infusorial earth to absorb
fluids, and consists in mixing the oiled material viz-wool, horse-hair, woollen
fabrics &c with infusorial earth in a suitable vessel heated in any suitable manner
10 or 20 degrees centigrade above the melting point of the oil or grease during
which the whole is stirred to insure the thorough cleansing of the material.
When the oil has been extracted it (the wool &c) is spread in thin layers on a
strainer and exposed to a shower of hot water which carries away the infusorial
earth leaving the material clean and ready to be dried in any suitable manner.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The method of scouring or removing the oil from animal and vegetable
substances by means of infusorial earth and heat as hereinbefore described.
