improvements in Deus.
I, RICHARD PARKER, of Heapey Copper Works, Heapey, in the County of
Lancaster, Machine Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in the construction of sliver cans to
render them more durable and less liable to accidental injury.
Hitherto the top hoop or ring has been made flat or plain and secured to the can
by soldering so that it was dependent entirely upon the solder to maintain it in its
place.
I find that by constructing the top hoop with an annular groove around the side
and swaging the edge of the can into the groove a much stronger and more
permanent structure is obtained.
In carrying out the invention I have the metal from which the top hoop is formed
rolled or otherwise formed with a deep groove which- when it is bent into a ring-
is in the face that comes into contact with the metal of the can. This groove is
of V or other suitable shape. When placed in position the edge of the can
is swaged or pressed by a suitable tool into the groove. The two parts are also
soldered together as is now customary.
A joint is thus formed not depending solely on the solder to maintain the hoop
in position and one that will be less liable to injury or damage.

Improvements in Sliver Cans.
I, RICHARD PARKER, of Heapey Copper Works, Heapey, in the County of
Lancaster, Machine Maker, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to improvements in the construction of sliver cans to render
them more durable and less liable to accidental injury.
Hitherto the top hoop or ring has been made flat or plain and secured to the can
by soldering so that it was dependent entirely upon the solder to maintain it in its
place.
I find that by constructing the top hoop with an annular groove around the side

page_text: and swaging the edge of the can into the groove a much stronger and more
permanent structure is obtained.
The invention will be fully described with reference to the accompanying
drawings :-
Fig. 1 side elevation.
Fig. 2 vertical section.
The top hoop A is made or formed from metal in which is rolled or otherwise
formed a deep groove a which when the metal is bent into a hoop or ring is in the
face thereof that comes into contact with the body B of the can.
The groove a in the hoop A is preferably of V shape though it may be of any
other desired shape or form and as I prefer to place the edge of the hoop A inside
the body B of the can the groove is formed on the outside. The hoop A may
however be placed outside the body B and the groove a formed on the inside.
When the hoop A is placed in position the top edge b of the body B of the can is
swaged or pressed into the groove by a suitable tool. The hoop is also soldered to
the body as is now customary.
A joint is thus formed not depending solely on the solder to maintain the hoop in
position and one that will be less liable to injury or damage.
The bottom C of the can is formed and attached as described in the Specification
of my former Patent No. 8501 of 1897.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A sliver can in which the top hoop is attached to the body by swaging the top
edge into a groove formed in the face of the hoop substantially as described.
2. A sliver can having the parts constructed and arranged together in combination
substantially as described and shown.
