COMPLETE SPECIFICATION.
Improvements in Sliver Cans and in Machines for Manufacturing
the same.
I, JAMES ANDERTON SUTCLIFFE, of Crumpsall Mills, Harpurhey, Manchester,
in the County of Lancaster, Sheet Metal Engineer, do hereby declare the nature
of this invention and in what manner the same is to be performed to be par-
ticularly described and ascertained.in and by the following statement: -
This invention relates to improvements in the manufacture of sliver cans with
the obiect of producing an improved can at a reduced cost.
In the accompanying drawings Figs. 1 and 2 are front elevations of sliver
cans constructed in accordance with my invention, Figs. 3 and 4 are respectively
vertical sections of the same.
Fig. 5 is a side view and Fig. 6 an end view of a machine which I employ in
the manufacture of said cans.
In these drawings similar letters refer to similar parts.
For the purpose of this invention I form the bottom of the can in the manner
described in the Specification of the Patents granted to me numbered No. 12,888
dated 1889, and 28,002 dated 1897.
In order to produce corrugations thereon as described in the last named specifi-
cation I employ a machine such as is shown in Figs. 5 and 6 which is constructed
with a bed a having vertical standards bb, at either end, in which bearings for
shafts c c, are fitted: said shafts project at one or both ends of the machine and
are fitted at one end with suitable gearing as g by which they may be rotated
simultaneously at enual speed.. I fit on the opposite and projecting ends of said
shafts a pair of rolls as d, done of said rolls being provided with suitably
formed projections as, and the other with recesses d³ corresponding thereto.
The hottom shaft e rotates in fixed bearings but the front bearing e of the upper
shaft is formed so as to slide and is capable of being raised to a slight extent
or be pressed down into a position parallel with the shaft c by means of a screw f
or an equivalent. In order to produce the required corrugations on any portion
of the can the bearing e is raised a short distance by the screw f which thereby
separates the rolls d and when the upper portion of the can bottom or other
portion of the can is placed on over the bottom roll and the top roll is brought
down in a parallel position by the aforesaid screw.
C
Any preferred form of corrugation according to the rolls that are placed on
the shafts and c is by these means produced. In order to unite the body of
the can to the bottom I form the lower portion of said body bell mouthed as j¹
so as to receive the upper edge of the upper portion of the can bottom, and
either rivet them together as shown in Figs. 1 and 3 or join them by placing the
can on the roll herein before described and corrugating the two parts where they
overlap. In some cases I unite the body of the can i to the upper portion of the
can bottom by inserting the lower portion of the body of the can into the
upper portion of the can bottom with the lower edge of the can body resting on
the bend in the can bottom as shown in Fig. 4. and then corrugating, both parts
together either by longitudinal corrugations ³, diagonal corrugations as jor

page_text: vertical corrugations as j³ by means of the rolls herein before described, which
are provided with the required projections and indentations.
It is obvious that any portion or the whole of a sliver can may be corrugated in
like manner, and the shafts which carry the rolls may if preferred be placed in
the same plane in the frame so, that the rolls may be side by side in lieu of
being one over the other without departing from this invention.
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 sliver can that is produced by forming the lower portion of the body of
said can bell-mouthed and joining thereto either by rivetting or corrugating the
upper portion of a can bottom that is provided with a spring or buffer substantially
as and for the purpose herein before described and shown in Figs. 1 and 3 on
the drawings.
2. A sliver can that is produced by forming the lower portion of the body of
said can bell-mouthed in which to insert the upper edge of the upper portion of
a can bottom of any preferred pattern, the two parts being united either by
rivetting, soldering or corrugating said two parts together substantially as
herein before described.
3. A sliver can that is produced by placing the lower portion of a can body
within the upper portion of a can bottoin with the lower edge of said can body
resting on the bend in the can bottom and united by corrugating both parts
together in the manner substantially as hereinbefore described.
4. A machine such as is shown in Figs. 5 and 6 on the drawings for the pro-
duction of corrugations of any form in any portions of or in the manufacture
of sliver cans in the manner substantially as and for the purpose hereinbefore
described.
