PROVISIONAL SPECIFICATION left by the said Henry Crouch Batchelor at
the Office of the Commissioners of Patents on the 26th March 1877.
HENRY CROUCH BATCHELOR, of 110, Cannon Street, in the City of London.
"IMPROVEMENTS IN COATING OR IMPREGNATING THE INTERIOR OF CASKS, AND
IN PROTECTING TIMBER, STONE, METALS, AND EARTHENWARE."
This Invention has more especially for its object to give to the interior of casks
a protecting coating which will prevent them fouling, and will enable them to be
readily cleansed. For this purpose I employ a certain mineral pitch found in
Equador and in the borders of Peru, and which has the property of not being soluble
in alcohol. This I dissolve in bisulphide of carbon, petroleum spirit, benzoline, or
other hydrocarbon, and coat or impregnate the interior of casks with the solution.
To effect this it is only necessary to pour some of the solution into an empty and
dry cask and run the solution over the whole interior surface. Afterwards the
portion of the solution which is not absorbed by the wood is run off and the coating
allowed to dry. The coating so given to the interior of the cask is perfectly
insoluble in water, alcohol, and most acids and alkalies, even when heated to above
212° Fahrenheit, and boiling water does not remove it. The coating also gives no
taste to liquors stored or contained in the casks; it also affords a ready means of
curing musty casks.
The solution above described may also be applied generally as a protecting coat-
ing to the surfaces of timber, stone, metals, and earthenware.

The solution above described may also be applied generally as a protecting coating

In witness whereof, I, the said Henry Crouch Batchelor, have hereunto set my
hand and seal, this Fourteenth day of September, in the year of our Lord
One thousand eight hundred and seventy-seven.
