PROVISIONAL SPECIFICATION.
An Improvement in Sheet Metal Cans.
I, JOHN HENRY MOYSEY, of No. 183 Bow Road in the County of London.
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to a construction of the mouth and cover of a sheet metal
can in a simple and inexpensive manner, and of such a kind that there is no
projection beyond the side of the can such as would occupy space in packing. I
Lice the can (which may have its bottom already fixed to it) in a mould fitting it,
under a die which is hollowed to some depth also to fit the can, the hollow
terminating in a rounded groove. On forcing down the die till the edge of its
bollow meets the edge of the mould which forms a stop for it, the metal of the can,
which originally extended above the mould to a height somewhat greater than the
depth of the hollow in the die, has its upper lip turned inwards by the rounded
groove of the die so as to form a rounded bead which stiffens the edge of the can,
and affords a seating for the cover. I stamp the cover so as to form on its
underside a shoulder a little coned which can be forced into the mouth of the can,
the shoulder bearing against the inner periphery of the bead, whilst the edge of the
cover beyond the shoulder rests on the upper surface of the bead.
Instead of forming the bead by the pressure of a die, it may be formed by the
pressure of a wheel having a rounded groove rolling along the edge of the can
presented to it at a varying inclination.

1, JOHN HENRY MOYSEY, of No. 183 Bow Road, in the County of London,
Engineer, do hereby declare the 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 :-
My invention relates to a construction of the mouth and cover of a sheet metal
can in a simple and inexpensive manner, and of such a kind that there is no
projection beyond the side of the can such as would occupy space in packing.
Fig. 1 of the accompanying drawings is a vertical section of a can with mouth
and lid according to this invention.
Fig. 2 is a section to an enlarged scale shewing the head at the mouth of the can
and part of the lid.
Fig. 3 is a section of the tool employed to form the head.
I place the can A (which may have its bottom B already fixed to it) in a
mould F fitting it, under a die D which is hollowed to some depth also to fit the cap,
the hollow terminating in a rounded groove G. On forcing down the die till the
edge of its hollow meets the edge of the mould which forms a stop for it, the
metal of the can, which originally extended above the mould to a height somewhat

page_text: greater than the depth of the hollow in the die D has its upper lip turned inwards
by the rounded groove G of the die so as to form a rounded bead H which stiffens
the edge of the can, and affords a seating for the cover. I stamp the cover L so as
to form on its underside a shoulder a little coned which can be forced into the mouth
of the can, the shoulder bearing against the inner periphery of the bead H whilst
the edge of the cover beyond the shoulder rests on the upper surface of the bead.
Instead of forming the bead by the pressure of a die, it may be formed by the
pressure of a wheel having a rounded groove rolling along the edge of the can
presented to it at a varying inclination.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
A sheet metal can having an inwardly projecting bead formed at its upper
edge, substantially as and for the purpose set forth.
