Improvements in the Construction of Sliver and other Cans..
We DANIEL HALL and JAMES HENRY KAY both of Stockport Road Ashton-
under-Lyne in the County of Lancaster, Tin Plate Workers, do hereby declare the
nature of this invention to be as follows:-
This invention is designed principally to be used in the construction of the cans
used in cotton mills or manufactories and known by the name of "sliver cans" but
it is also applicable to the cans used for the conveyance of milk, and for other
purposes.
The object of the invention is to prevent the injury to which the bottom rim of
the can is liable on being set down heavily on a stone or other floor and thus to
increase the durability of the can, without materially increasing its weight.
For this purpose we make the bottom of the can of rather smaller diameter than
the body of the can so as to leave a shoulder all round the same.
The strengthening band we make preferably of the same metal as the body
doubling or bending the same upwards from the bottom so as to increase its
strength and on the inside thereof at the bottom we form a rim by folding the metal
inwards.
We form a ring of wrought iron or steel with an outer, flange or shoulder at the
top and of such a diameter that if placed inside the strengthening band the inside
rim of the latter will support the outside shoulder of the former and prevent it from
falling out.
We place an india rubber ring round the reduced part of the bottom of the can
against the shoulder, and having slipped the iron or steel ring inside the
strengthening band we pass the latter over the bottom of the can and press it on
until the india rubber band is held firmly between the shoulder at the bottom of the
can and the top of the iron or steel ring. We then solder the strengthening band
onto the can in the usual manner.
The parts are so arranged that the bottom of the strengthening band and that of
the can are about level with each other and the lower edge of the iron or steel ring
projects about half an inch or so below them. It will be evident therefore that
when the can is in use the iron or steel ring first meets the floor and as the india
rubber ring between it and the shoulder at the bottom of the can forms an elastic
bed or cushion it will absorb all shock and prevent injury to the can, and as there
is only one iron ring of about the ordinary depth the weight of the can is not
appreciably increased which in cotton mills, where the cans are principally handled
by women or young persons, is a very great advantage.
The capacity of the can also is increased as the bottom is thus brought nearer than
usual to the ground.

Improvements in the Construction of Sliver and other Cans.
We DANIEL HALL and JAMES HENRY KAY both of Stockport Road Ashton-
under-Lyne in the County of Lancaster, Tin Plate Workers, do hereby declare the
5 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 :—

purposes.
The object of this invention is to prevent the injury to which the bottom rim of
the can is liable on being set down heavily on a stone or other floor, and thus to
increase the durability of the can without materially increasing its weight.
The nature of our invention and the manner in which the same is to be performed
or carried into practical effect will be readily understood on reference to the annexed
sheet of drawings and the following explanation thereof.
Fig. 1 is a vertical section showing the detached portions of the can bottom and
Fig. 2 is a similar view shewing the parts put together with the india rubber buffer
ring in its place.
For the purposes of our invention we make the bottom part of the can a of rather
smaller diameter than the body a' of the can so as to leave a shoulder at b all round
the same.
The strengthening band c we make preferably of the same metal as the body (or
it may be of stronger material) doubling or bending the same upwards from the
bottom as shown at c' so as to increase its strength, and on the inside thereof at the
bottom we form a rim or inner shoulder by folding the doubled metal inwards as
shown at c².
We form a ring d of wrought iron or steel with an outer flange or shoulder d' at
the top and of such a diameter that if placed inside the strengthening band c the
inside rim of the latter will support the outside shoulder d¹ of the former and
prevent it from falling out.
We place an india rubber ringe (Fig. 2) round the reduced part a of the bottom of
the can against the shoulder band having slipped the iron or steel ring d inside the
strengthening band we pass the latter over the bottom a of the can and press it
on until the india rubber band e is held firmly between the shoulder b at the bottom
of the can and the top of the iron or steel ring d. We then solder the strengthening
band c onto the can in the usual manner.
The parts are so arranged that the bottom of the strengthening band c and that
of the can a are about level with each other, and the lower edge of the iron or steel
ring projects about half an inch or so below them as seen at Fig. 2.
It will be
evident therefore that when the can is in use the iron or steel ring d first meets the
floor and as the india rubber ring e between it and the shoulder b at the bottom of
the can forms an elastic bed or cushion, it will absorb all shock and prevent injury
to the can, and as there is only one iron ring of about the ordinary depth the weight
of the can is not appreciably increased, which in cotton mills where the cans are
principally handled by women or young persons is a very great advantage. The
capacity of the can is also increased, as the bottom is thus brought nearer than
usual to the ground,
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is :-
The special construction and application to sliver and other cans of the elastic
protecting rim substantially in the manner herein before described and illustrated by
the drawings annexed.
