Improvements in and in the Construction of Sliver or Coiler Cans.
We, SILAS WALMSLEY, of 44, St. Mary's Road, Bamber Bridge, Preston, in the
County of Lancaster, Head Carder, and JOSEPH KNIGHT, of 52, Manchester Road,
Frenchwood, Preston, aforesaid, Iron and Tin-plate Worker, do hereby declare the
nature of this invention to be as follows:-
-
Our said invention relates to improvements in and in the construction of cans
used to contain slivers of cotton during the preparation and spinning of the
same.
These cans are usually formed from sheet metal bent to a circular form, a flat
strengthening ring being inserted at the bottom whilst a further ring or bead
is also used at the top of the can. The flat ring at the foot of the can is generally
secured by rivetting and the can bottom is held in position by solder. Cans so
constructed are not so durable as is desirable and soon require repair or become
useless. The sharp or angular edges of such can bottoms are also liable to cause
damage to the flooring or surrounding objects as the cans are dragged or moved
about.
The object of our invention is to construct a can which shall be more lasting
and not likely to cause damage by concussion with the floor.
According to our invention we form the body of the can from sheet metal as
usual but we force the lower and upper edges of the can into metallic rings of a
suitable formation. The ring for the bottom or lower end of the can is turned
with two lips or ledges the inner lip or ledge standing higher or projecting beyond
the outer lip or ledge. Between these two lips or ledges is an annular depression.
or groove whilst the lower outside edge of the ring is carefully rounded off. The
lower end of the can is forced or sweated over the inner lip or ledge down on the ring
until such time as the lower end of the can occupies the annular groove in the
ring when the connection is complete. We might form the outer face of the
inner lip slightly taper and we may cause the inner edge of the outer lip or ledge.
to overhang the groove.
The can bottom which would be a circular disc rests all round on the top of the
inner lip or ledge and may be laid on the ring before the can end is inserted
thereinto.
The ring for the top of the can is practically of the same formation as that used
for the bottom but is of course inverted when in position:
In building up the cans we might slip flat rings around the can body before the
ends are inserted into the top and bottom strengthening rings such flat rings being
afterwards forced down into the annular grooves so as to more securely retain the
can body or we might force strips into such grooves with the same object.
In some cases we might dispense with.a special ring for the top of the can. In
forming any or all of the joints we may employ solder to gain additional security.
Cans constructed in accordance with our invention are exceedingly strong and

page_text: durable and owing to the bottom ring being carefully rounded off the can is more
easily dragged about and with less damage to the flooring &c.
We might fit the top of each can with a semi-circular hoop or bent strip which
would tend to retain the sliver safely in the interior of the can, the hoop or strip
being hinged or pivotted to the top ring or can body so as to permit of its being
folded or turned down when requisite.
Improvements in and in the Construction of Sliver or Coiler Cans.
We, SILAS WALMSLEY, of 44, St. Mary's Road, Bamber Bridge, Preston, in the
County of Lancaster, Head Carder, and JOSEPH KNIGHT, of 52, Manchester Road,
Frenchwood, Preston, aforesaid, Iron and Tin-plate Worker, 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 and
accompanying drawings;-
-
Our said invention relates to improvements in and in the construction of cans
used to contain slivers of cotton during the preparation and spinning of the
Bame.
These cans are usually formed from sheet metal bent to a circular form, a flat
strengthening ring being inserted at the bottom whilst a further ring or bead
is also used at the top of the can. The flat ring at the foot of the can is generally
secured by rivetting and the can bottom is held in position by solder. Cans so
constructed are not so durable as is desirable and soon require repair or become
useless. The sharp or angular edges of such can bottoms are also liable to cause
damage to the flooring or surrounding objects as the cans are dragged or moved
about.
The object of our invention is to construct a can which shall be, more lasting
and not likely to cause damage by concussion with the floor.
Our invention will be clearly understood from the following description when
read in connection with the annexed sheet of drawings.
In the said drawings.
Fig. 1 shows the lower portion of a can constructed in accordance with our
invention, the left hand half being in section.
Fig. 2 is a view of a can on a smaller scale, the upper half being in section.
Fig. 3 is an exterior view of the upper end of the can.
Fig. 4 shows a slight modification in the form of section of the ring.
According to our invention we form the body a of the can from sheet metal as
usual, but we force the lower and upper edges of the can into metallic rings b, of
malleable iron, of a suitable formation or section. The ring for the bottom or
lower end of the can is turned with two lips or ledges 12 the inner lip or ledge ↳
standing higher or projecting beyond the outer lip or ledge b².
Between these two lips or ledges is an annular depression or groove whilst the
lower outside edge of the ring, or it might be both edges is or are carefully rounded
off. The lower end of the can is forced or sweated over the inner lip or ledge b¹
down on the ring, until such time as the lower end of the can occupies the annular
groove in the ring when the joint is made secure with solder or the like and the

page_text: connection is complete. We might form the outer face of the inner lip slightly
taper and we may cause the inner edge of the outer lip or ledge to overhang the
groove.
The can bottom e, which would be a circular disc, rests all round on the top of the
inner lip or ledge b' and may be laid on the ring before the can bottom is inserted
thereinto.
The ring e for the top of the can is practically of the same formation as that used
for the bottom, but is of course inverted when in position. This ring c may be of
a slightly lighter section than the ring b.
In building up the cans we might slip flat rings around the can body before the
ends are inserted into the top and bottom strengthening rings such flat rings being
afterwards forced down into the annular grooves so as to more securely retain the
can body or we might force strips into such grooves with the same object.
In some cases we might dispense with a special ring for the top of the can. In
forming any or all of the joints we may employ solder to gain additional security.
The sections forming the body of the can, may be soldered, rivetted, or otherwise
secured together.
Cans constructed in accordance with our invention are exceedingly strong and
durable, and owing to the bottom ring being carefully rounded off the can is more
easily dragged about and with less damage to the flooring &c.
We might fit the top of such cans with a semi-circular hoop or bent strip d
which would tend to retain the sliver safely in the interior of the can, the hoop
or strip being hinged or pivotted at to the can body, so as to permit of its being
folded down when required as indicated in Figs. 2 and 3.
This hoop would also serve as a handle when moving the can about.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
:
1) In constructing cans for containing cotton slivers and the like, forcing the
can ends into a depression or annular groove formed in an annular metallic ring
the joint being made secure by solder or the like substantially as described and
shown.
2) A coiler can, having end rings be forced on the body of the can and pro-
vided with a pivotted hoop d substantially as herein described and illustrated in
the annexed drawing.
