PROVISIONAL SPECIFICATION.
Improvements in and in the Manufacture of Cans and Receptacles
for Textile Materials.
We GEORGE ASHWORTH and ELIJAH ASHWORTH of the firm of Ashworth
Brothers of The Moss Brook Works, Collyhurst, Manchester, in the County of
Lancaster, Engineers, do hereby declare the nature of this invention to be as
follows
Our invention relates principally to the receptacles for cotton or textile material
in process of manufacture now well known under the designation of "sliver cans.'
Such cans are cominonly made of turned sheet iron strengthened by means of iron
hoops riveted and soldered to the can bodies and being subjected to rough treatinent
do not last long without requiring repairs such repairs being costly compared
with the original cost of the can.
Our improved can has a seamless cylindrical body made of coiled paper such
body being strengthened and protected at each end by means of clip rings which
enclose the end edges of the shell and are closed so as to firmly grip the shell.
The shell is provided with a bottom and is or may be further strengthened at the
lower end by means of a protecting foot band or ring or sheet metal ring. The
said clip rings are by preference made of sheet steel cut or formed into or in strips
which are bent into an U or a J section. Lengths of these bent strips are formed
into rings which are applied to the ends of the cylindrical shell so as to enclose the
extreme ends of the same. The joints of the U shaped clip rings might be made
up or strengthened by short pieces of a similar section inserted loose or soldered
in position. The shell is mounted in a suitable machine whereby the shell can
be revolved upon its axis and wheels are brought against the inside and outside of
the ring and are pressed toward the ring so as to close the ring upon the shell or
one wheel may be a bed or supporting wheel the other wheel being set up to give
the pressure or if preferred the ring might be closed by means of dies. The foot
band would be made of sheet steel and preferably of hard or tough steel or would
be toughened, and would be put on tight or be shrunk on and would be secured by
means of rivets or screws or by suitable means. The bottom clip ring might be
applied so as to enclose one end of the foot band in addition to the end of the can
shell or the clip ring might be riveted or secured to the foot band or the can
bottom before application to the can body. The can bottom may be made of
tinned sheet metal or of sheet steel or of paper or wood or other suitable material.
The sheet metal bottom might be plain or be corrugated and would by preference
be stamped pressed or spun into a dished form so that its edge could be enclosed
by the clip ring whereby the bottom would be secured in position or the bottom
might be secured or additionally secured by means of rivets passing through the
flanged edge and the foot band. Bottoms made of paper or wood might be secured
by means of nails or screws, and might or might not be dished. The cylindrical
shell might be made thicker at the lower end or with two or more thicker bands so
as to increase the strength of the shell. We also propose to apply our invention
in the manufacture of other receptacles for textile materials by making the propor-
tions of the receptacles suitable to their intended uses.

Improvements in and in the Manufacture of Cans and Receptacles
for Textile Materials.
We GEORGE ASHWORTH and ELIJAH ASHWORTH of the firm of Ashworth
Brothers, of The Moss Brook Works, Collyhurst, Manchester, in the County of
Lancaster, Engineers, 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 invention relates principally to the receptacles for cotton or textile
material in process of manufacture now well known under the designation of
sliver cans."

Such cans are commonly made of turned sheet iron strengthened by means of
iron hoops riveted and soldered to the can bodies, and being subjected to rough
treatment do not last long without requiring repairs, such repairs being costly
compared with the original cost of the can.
Our improved can has a seamless cylindrical body made of coiled paper such
body being strengthened and protected at each end by means of clip rings which
enclose the end edges of the shell and are closed so as to firmly grip the shell. The
shell is provided with a bottom and is or may be further strengthened at the lower
end by means of a protecting foot band or ring of sheet metal.
To render our invention well understood we will now proceed more particularly
to describe the same with reference to the annexed sheet of drawings.
Fig. 1, is a view of the top and bottom of a sliver can fashioned in accordance
with our improvements.
Figs. 2, 3 and 4 illustrate modifications of our improvements.
Figs. 5 to 10 show the method of forming and also some modifications in the shape
of our improved clip rings for sliver cans.
It must be understood that it is not new to make the bodies of sliver cans from
paper, as this has been done previous to the date of our present application.
Our invention relates only to the improved means for mounting and strengthening
such paper bodies.
With this object we surround the top and bottom edges of the paper cylinder
with strengthening clip rings of metal. For example referring to Fig. 1, the top
edge of the paper body a is protected and strengthened by the embracing clip b
of steel or other suitable metal. This clip ring is made in the following manner.
We take a strip of sheet metal and by preference of sheet steel such for example as
is shown in Fig. 5, and roll or bend it by suitable means into the U shape shown at
Fig. 6. A length of this U section is formed into a ring which is applied to the
upper edge of the cylindrical shell a so as to cover in and protect the same.
joint of the ring is made up or strengthened by a short U shaped piece c which is
inserted at the joint and is either loose or soldered in position.
The
Fig. 1 is a perspective view of the making up piece e projecting from the ring b
at the joint. The piece c is preferably thinner than the clip ring and as the ring b
is forced on under considerable pressure the piece e becomes sunk in the paper edge
and does not interfere with the bedding of the ring at that point. When the ring b
has been thus placed on the upper edge of the cylinder the shell a is mounted in a
suitable machine whereby the shell can be revolved upon its axis and wheels or
closing tools are brought against the inside and outside of the ring and pressed
towards each other so as to close the ring upon the shell and cause it to assume the
appearance shown at Fig. 1. The edges of the clip ring bite into the paper and
hold the ring firmly in position so that no rivets or fasteners are necessary to keep
it firmly on the shell." The presser wheels for closing the ring might both be
capable of being set towards each other or one might be fixed and the other

page_text: movable; or the ring might be closed by means of dies. Referring now to the foot
of the shell in the same Fig. 1 it will be seen that the lower part of the shell is
encircled by a band or foot ring e of hard or toughened sheet steel, which is pressed
or shrunk on to the foot of the sliver can so as to firmly enclose the same. If
necessary rivets or other means might be employed to hold this foot ring more
securely in position. The bottom clip ring fis applied and closed over the bottom
edge of the cylinder so as to cover in the lower edge of the foot band e in addition
to the lower edge of the can shell a.
In Fig. 1, the bottom g of the can or receptacle is made of paper or wood or
other suitable material and might if thought desirable be secured to the shell by
means of screws hor of sprigs or nails.
The bottom clip ring is set in or closed by means similar to those employed to
close up the top ring..
Fig. 7, is an enlarged view of the bottom ring when closed up. As indicated in
the drawing the inner edge of the clip ring bites into the paper shell and also
presents an annular ledge upon which the bottom g rests.
To assist the grip of the clip ring edge on the paper shell the edge might be left
ragged or rough or might be serrated or have one or two small teeth to enter and
grip the paper shell.
In Fig. 2, the foot clip ring is constructed by bending over the lower edge of
the foot band e. In this case also a bottom of paper or wood or the like
is used.
In Fig. 3 however the bottom g' consists of sheet metal and the clip ring is
made by dishing the bottom and bending the dished rim into a clip section as clearly
shown by the fig.
In Fig. 4 the bottom gl.is made separate from the clip ring.
The bottom is
dished so as to present a downwardly projecting edge and the clip ring f when
applied and closed up embraces and holds the dished edge of the bottom, the edge
of the shella and the edge of the foot band e, all three together.
The sheet metal bottom g' might be corrugated if it were wished to gain greater
strength.
The cylindrical shell a might be made thicker at the lower end or with two or
more thicker bands so as to increase the strength of the shell or to give a better
hold-fast for the clip ring. In some cases we might form a shallow groove in the
foot band e at the point where the edge of the clip ring grips. The edge would
thus have a better hold than if clenched down on the smooth metal surface of the
foot band.
As the clip rings at the foot are necessarily subject to the greatest wear at the
point where they come in contact with the floor, we might thicken them at this
point. For example we might roll metal strips of the section shown at Fig. 8, which
when bent into the U shape as at Fig. 9, would present increased thickness at the
part coming in contact with the floor.
We might also cast the clip rings in malleable iron as shown at Fig. 10, and the
groove to receive the edge of the shell might either be formed in casting or the ring
might be cast solid and the groove turned out.
The invention is applicable not only in the manufacture of so called "sliver
but also in the production of other receptacles for textile materials.
