Complete Specification Left, 20th Nov., 1897-Accepted, 5th Mar., 1898
I, JOHN MCDONALD, of James Street, in the City of Petrolia, County of Lambton,
Province of Ontario, Dominion of Canada, Engineer, do hereby declare the nature
of this invention to be as follows:-
:-
The cask of this invention is formed by bending a flat plate of any suitable.
metal into a cylindrical shape with overlapping edges rivetted or soldered together.
On the outside of the cylinder at the places where the hoops are to come, are
rivetted or otherwise secured flat strips of metal upon which the hoops are driven.
and then the ends of the flat strips turned up at the ends to secure the hoops in
place. The bilge of the cask is formed by making the central hoop thicker than
the others or by a gradual reduction in the thickness of the same from the central
to the end hoops. The hoops may be of metal or wood. The ends of the cask are
made of a flanged sheet of metal secured by rivetting or soldering or both. A bung
hole and a vent hole is provided at a suitable part of the cask.

Improvements in Metallic Casks.
I, JOHN MCDONALD, of James Street, in the City of Petrolia, County of Lambton,
Province of Ontario, Dominion of Canada, Engineer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
The metallic cask of this invention is shewn in the accompanying drawing, Fig. 1
being an elevation thereof, Fig. 2 a central vertical section, Fig. 3 a horizontal
section and Fig. 4 a detail of construction on an enlarged scale."
R is the cask body of metal such as iron or steel and formed by bending into
a cylindrical or other desired form a flat plate of metal of the required size until
the sides edges overlap each other. The overlapping edges are then rivetted and
soldered or otherwise firmly secured to form a tight joint.
C are clips formed of flat strips of metal and are rivetted or otherwise secured to
the body R and one, two, or any number of them in connection with each hoop
as desired.
Dare wooden hoops although they may also be of other suitable material. They

page_text: are driven on to the cask body and over the metal strips upon which they are
adjusted after which the ends of the strips are turned up to form clips (Fig. 4)
by which, accidental displacement of the hoops is prevented. The hoops D protect
the cask body, and the central hoop is made thicker or set out further from the cask
body than the other or end hoops, or the hoops may gradually decrease in thickness
from the centre to each end by which construction the bilge of the cask is formed
in the hoops and not in the body.
Hare the heads of the cask preferably formed in one piece and with the
flanges A, by which latter they may be conveniently rivetted and soldered or other-
wise rigidly secured to the ends of the body R and form a tight joint at these
points.
B, 13, are orifices in the cask for filling it and withdrawing its contents, and for
closing said orifices suitable bungs or stoppers may be used.
E is a vent to be closed after the cask is filled.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:
1. In a cask, a body R formed of metal and metal clips C secured thereto, in com-
bination with hoops D of wood or other equivalent material the accidental dis-
placement of the latter being prevented by the bending up the ends of said clips
after the hoops have been driven thereon, substantially as described and shewn.
2. In a cask, a body R formed of metal in combination with hoops D the central
one of which is thicker or set out further from the body R than the other or end
hoops or the thickness of said hoops from the centre to each end gradually de-
decreased,, whereby the bilge is formed in said hoops instead of in said body, sub-
stantially as described and shewn.
3. In a cask, a body R of metal formed by bending into a cylindrical or other
suitable form a flat sheet of metal and overlapping the side edges of said sheet and
rivetting and soldering or otherwise securing the overlapping edges together to
form a tight joint, and metal clips C secured to said body, in combination with the
hoops D of wood or other equivalent material, the accidental displacement of said
hoops being prevented by bending up the ends of said clips C after the hoops D)
have been driven thereon, substantially as described and shewn.
4. The general construction, arrangement, and combination of parts constituting
the metallic cask, substantially as described and shewn.
Dated this 20th day. of November 1897.
