I, WILLIAM NOAKES of 142 Spa Road, Bermondsey, in the County of Surrey,
Manager to B. Noakes & Co., Iron Cask Manufacturers &c. do hereby declare the nature
of this invention to be as follows:-
This invention has for its object improvements in the manufacture of metal cans.
In making cans having conical tops the usual method of connecting the top with
the cylindrical drum or body is to shape the rim or edge of the cone top to a cylindrical
form and such dimensions that it will fit tightly over the edge of the drum.
After the top has been applied to the drum the joint is rendered water tight by
solder.
This shaping of the rim or edge of the cone can be effected by pressure in dies.
Cans of this construction are weak where the top meets the drum and if here they
receive a blow they are liable to leak.
In making cans according to this invention the cone top is provided with a deeper
cylindrical rim or flange than heretofore and when it has been placed on the drum or
body of the can an annular groove or corrugation is formed on the edges of the two
parts. An arm carrying a roller convex on the face is inserted within the drum (which
has not yet received its bottom) and another roller concave on the face is pressed
against the exterior of the can so that the edge of the conical top and the edge of the
drum are nipped together between the rollers. The rollers revolve and in so doing
produce the annular corrugation. The joint is rendered water tight by solder as
heretofore.
The double corrugation so strengthens the parts that the can will bear much rough
usage without risk of leakage.

nature of this invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:-

In order that my said invention may be most fully understood and readily carried
into effect I will proceed to describe the drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
The drawing shows a section of a can made in accordance with my invention together
with the rolls for producing the joint between the body and conical top.
The mode of mounting and driving these rolls is not shown, this may be done in any
convenient manner so long as one of the rolls is so mounted that it can be moved away
from the other to allow of the insertion of the can. The rolls are then caused to
revolve and to gradually approach one another until they asssume the position
shown.
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 manufacture of metal cans substantially as described.
