Improvements in Doffing and Weft Cans.
We, JAMES ANDERTON SUTCLIFFE, of Claremont Villa, Crumpsall, Manchester,
Sheet Metal Engineer, and MARY SUTCLIFFE, Widow, of 26, Sumner Street,
Blackburn, both in the County of Lancaster do hereby declare the nature of this
invention to be as follows:-
Istamp in a drawing press a doffing or weft can out of a thin sheet of metal
preferably sheet steel, by the process of drawing the cans are rendered extremely
hard & durable caused by the compression of the sheet metal. By being drawn
from one sheet of metal the cans are rendered seamless & shaped with rounded
corners at the bottom part of the can. At the top of the can I enclose an endless
wire rod which I encase with a flange thrown from the top part of the sheet
metal stamping & after this rod is encased the whole can is dipped overhead in
molten metal preferably tin or zinc so as to prevent moisture deteriorating the
metal & also to fasten the steel rod which I encase in the top part of the can.
The result of this dipping is that it fills up the space in the top wherein the end-
less rod is encased thereby rendering the rod & casing into one solid mass this
will effectually resist blows & rougli usage to which such cans are subjected in
cotton & other mills. The handles of these cans I prefer to make with recesses
in so that they are not damaged when being thrown into each other.
In doffing & weft cans that are made & used at the present time there is great
wear & tear caused by the cans being made in a number of pieces of soft sheet
metal which give way & the seams come loose & where the joints are made the
edges get frayed & catch upon the yarn in the cans this causes damage to the
fibre. There is also a very great weakness caused by the wire beding which is
put in the top of the can being put in, in 2 halves these joints invariably break
asunder & tear the thin sheet metal away with the wire. In cans also of ordinary
construction they are made with square corners along the bottom this causes
them to knock in & break away, this is also the cause of many workpeople
getting badly cut & scratched. The handles of ordinary cans get much damaged
&torn off by being thrown into one another & catching each other, this causes
much inconvenience besides being costly to repair.

JAMES ANDERTON SUTCLIFFE,
COMPLETE SPECIFICATION.

page_text: Blackburn, both in the County of Lancaster 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:-
This invention relates to an improved construction of doffing and weft caus
such as are employed in cotton mills and like places. The object of the invention
is to make said cans with a smooth internal surface by avoiding all joints, sharp
corners and the like which in doffing and weft cans as at present used that are
made in a number of parts of soft sheet metal soon become loose and where the
joints are made the edges of the metal get frayed and catch the yarn in the can
causing damage to the fibre: the wire beading also at the top of the can being
in two parts is frequently drawn asunder and tears the sheet metal away with
the wire.
In the accompanying drawing, Fig. 1 is a side view of my improved doffing
and weft can with a flat bottom, Fig. 2 is a transverse section of the same can
but with a corrugated bottom and Fig. 3 is a plan of the can. In these views
similar letters refer to similar parts.
According to our invention we stamp in a drawing press and produce from a
thin sheet of metal, preferably mild steel, a seamless doffing and weft can as a
with rounded corners as shown on the drawing. The compression of the metal
by the process of drawing renders the can extremely hard and durable and all
sharp corners or edges are avoided.
We form an endless hoop or band d either of rod iron or of angle iron which
we pass over the bottom of the can and place under the top flange 6 of the can to
which it is united by rolling over the edge b' of said flange; the bottom of
the can may be either plain as Fig. 1 or corrugated as Fig. 2 and battens e may
he affixed in the ordinary manner to protect the bottom of the can from injury.
We dip the can in molten metal, preferably tin or zinc, thereby preventing
moisture deteriorating the metal; and further securing and uniting the band
which encases the top of the can by filling up any space which may be left
between said band and the top flange 6 of the can thereby forming the band and
the flange into a solid edge, which also serves as a convenient means for handling
but hand holes may if required be formed in the flange.
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:-
1. A seamless doffing and weft can that is produced by stamping or pressing
a thin sheet of mild steel or other metal by which said can is formed in one piece
with rounded edges and corners and a perfectly smooth internal surface sub-
stantially as and for the purpose hereinbefore described.
2. A seamless doffing and weft can as described with an endless hoop or band
either of rod iron or angle iron placed under the top flange of said can and united
thereto by the flange being rolled over as shown in Fig. 2 on the drawing and
the can afterwards dipped in molten metal.
