We, DANIEL FRYER, of Carlton Square, Old Kent Road, in the County of
Surrey, and JOSEPH WILLIAM MEEARS, of Aunett's Crescent, Islington, in the
County of Middlesex, do hereby declare the nature of the said Invention for
IMPROVEMENTS IN CASKS, TANKS, OR OTHER RECEPTACLES FOR CONTAINING
PETROLEUM AND OTHER OILS OR SPIRITS," to be as follows:-
At present mineral, animal, or vegetable oils as well as spirituous liquids are
chiefly contained and conveyed from place to place by means of casks or iron
tanks into which the liquid is poured, and which casks or tanks are consequently
only suitable for containing fresh supplies or similar oils or spirits by reason of
their becoming impregnated with such liquids or spirits.
Now this Invention consists in the application of a moveable lining to the
interior of the cask, tank, or other receptacle for containing the above class of
liquids, the object being to prevent the contact of the oil or spirit with the
cask or receptacle itself and to obviate the consequent impregnation as well as
to prevent loss by leakage. The lining is to be made of a size and shape to
fit the interior of the cask or other receptacle, and is to be furnished with a
neck or tube of the same material as the lining, which is to be made of vulcan-
ised india-rubber, waterproof canvas, or any other waterproof or oilproof fabric
or material or compound. With respect to casks, the bung hole is to be
made in the head of the cask. The diameter of the bung hole should be not

page_text: less than four inches so as to enable the bag or lining to be rolled up and
inserted in the cask through the hole. The petroleum or other oil or spirit is
then to be poured in at the neck of the bag, and when full the bag is to be
closed by a ligature or by a screw cap or other fastening around the neck which
is then to be placed within the cask and a bung is then to be driven into the
hole for the sake of extra security. . On the arrival of the petroleum or other
liquid at its destination, the cask is to be opened and the neck of the lining
taken out, and the oil withdrawn, after which the lining itself may be
pulled through the bung hole leaving the cask dry and unaffected or unim-
pregnated in the least degree by the liquid or spirit it contained.
The india-rubber should be vulcanized under a temperature of about
240 degrees to enable it to withstand the action of the oils or spirits.
With respect to iron or wooden tanks or other receptacles for conveyance or
for containing the above liquids the principle of the Invention is the same,
the form of the lining only requiring to be varied accordingly. By this
Invention there will be no necessity to return the empty casks or vessels for
fresh supplies of oil or spirit, since they can be applied to contain other
substances or fluids without imparting to the contents any unpleasant odour or
flavour. The bags or linings after being emptied are to be rolled or folded up,
and packed together and returned for fresh supplies of oil or spirits; they would
require but a small space in comparison with that occupied by the casks or
vessels themselves, and a great saving in back freight would thus be effected,
the casks or other receptacles being retained for other uses.
