1, ROBERT STONE, of 101 Leadenhall street, in the City of London, Engineer, do
hereby declare the nature of my said invention to be as follows :—
My invention consists in the manufacture of improved barrels or casks.
One form of my invention consists in forming barrels of corrugated or plain metal,
such as sheet iron, tin, steel or other metal. The metal may be rolled or otherwise
formed so as to obtain the usual bilge form, or it may be used so as to form cylindrical
barrels or casks.
Another method consists in forming the barrel or cask of sheet metal as an inside
lining, and surrounding the same with wood or iron hoops at suitable distances from
each other, the barrel itself being covered with a coating of peat or saw-dust or other
analogous material mixed with Stockholm tar or any other suitable binding liquid or
other substance for causing the same to adhere to the barrel and become homo-
geneous. Or I use for such last named purpose cement or ground flint or cement
and ground flint with the aforesaid liquids, put on in a bot state; or cement and
flint intimately mixed and ground, and mixed with water, as required for setting
the cement. In some cases clean sand is mixed with the cement, and applied in the
saine manner.
I sometimes fit wooden heads to the casks or barrels instead of metallic heads.
In some cases I make the barrels or casks with a thin coating of composition, and
strengthen them inside with rings or stays.
My invention is especially applicable to the conveyance and storage of powdered
material or substances required to be kept free from damp, such as cement, plaster,
flour, and analogous materials.

page_text: I ROBERT STONE of 1 Leadenhall Street, in the City of London, Engineer, do
hereby declare the nature of my said invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
The object of my invention is to manufacture barrels or casks of metal, or partly
of metal and partly of other materials.
One method of carrying out my invention, consists in forming metallic barrels
with annular corrugations, such barrels being formed of equal diameter from end to
end, so as to assume the general form of a cylinder, or being formed with an
increased diameter towards and at the centre of their length, and of the usual bilge
form.
Another method consists in forming metallic barrels or casks, of plain motal, without
corrugations, and either cylindrical or of a bilge form.
Either of the aforesaid forms of barrels or casks may be fitted with metallic heads,
or wooden heads, according to the purpose for which they are intended to be used;
metallic heads, liermetically sealed, being used for oil, grease, and other fluids; the
heads being secured by means of grooves formed in the metal, or angle iron hoops,
rivetted or other wise secured to the casks or barrels.
My improved barrels are sometimes lined with wood, or other suitable material,
and also painted, varnished, or otherwise coated for preserving the same from rust
and other damage. I also sometimes apply, to plain cylindrical barrels, a mixture of
tar and cement, for imparting strength and stiffness to the same.
Barrels or casks constructed in accordance with my invention are especially suitable
for the conveyance and storage of cement, plaster of Paris, flour, and analogous
materials requiring to be kept free from damp.
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 1
claim is :-
1. The manufacture and use of barrels or casks constructed entirely of corrugated
or plain metal, substantially as hereinbefore described.
2. The manufacture and use of the improved barrels or casks fitted with wooden
ends or heads, substantially as herein before described.
