Improvement in Roving or Sliver Cans.
I, JOHN ANDREW COLLINS, of No. 73, Cottage Street, in the City of Fall River,
County of Bristol, State of Massachusetts, United States of America, Manufacturer,
do hereby declare the nature of my invention and in what manner the same is to
bo performed, to be particularly described and ascertained in and by the following
statement:
SPECIFICATION.
The invention has reference to an improvement in the cans used to receive the
roving or sliver from carding-engines, and consists in the peculiar and novel
construction by which the coiled roving is securely held in the can, as will be more
fully set forth hereinafter.
In the preparation of cotton for spinning, the sliver is delivered into the roving
cans by means of a coiler and, in the modern practice, the cans are filled so full
that the roving in its compressed condition extends to the top and usually above
the top of the can. As the roving is taken from the can to pass through the subse-
quent processes of drawing and doubling it is desirable that the roving should
remain in the coiled condition and yet be held to permit the transportation of the
cans from one part of the mill to other parts. A devico for securely holding the
roving should in no way disturb the sliver, it must hold the roving in the com-
pressed condition and, when released, must not interfere with the drawing of the
roving or sliver.
The object of this invention is to produce these results in a cheap and simple
manner.
Figure 1 is a side view of a roving can provided with a hold-down pin the head
of which is shown.
Figure 2 is a top view of a roving can showing the hold-down pin inserted.
Figure 3 is a sectional view of the upper end of a roving can provided with the
hold-down pin, and
Figure 4 is a side view of the hold-down pin.
In the drawings a designates the cylindrical sides of a roving can; b the beaded
upper edge of the can; c, c, two openings in the sides of the can near the upper
end;
da bar provided at one end with the head and near the head e with the
groove f.
The openings c, c, are made preferably circular and may be, and in the preferred
form are, provided with an eyelet secured in the opening. The bar d is preferably
made of wood; it is provided with a heade which acts as a stop and is provided
with a groove f which may be near either end, but preferably is placed near the
head as shown in the drawings, the groove f engages the bar d with the sides
of the can or with the eyelet or bushing in the openings c, c, to hold the bar in
the desired position.
When the can has been filled the roving is pushed down with one hand and the
bar dis inserted, the resiliency of the coiled roving acts against the bar d and
brings the groove f in engagement with the eyelet or walls of one of the holes 6,

the roving. When the can is to be emptied the bar d is pushed down and drawn
from the openings c, c, leaving the can free from any projections or obstructions
inside or outside. The bar also forms a convenient handle for moving the can.
Although the want of some simple means to confine the roving or coiled sliver
in the can during, the handling of tho can has long been felt, I am, as far as I
know, the first one to produce an officient hold-down adapted for roving cans.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the samo is to be performed, I declare that what
I claim is
Claim 1. In a roving can, the combination with the upper end of the can, of the
openings c, c, and the bar d provided with a groove adapted to engage with the
walls of one of the openings, whereby the bar, when inserted, is held in place, as
described.
2. In a roving can, the combination with the openings c, c, of the bar & having
the heade at one end and the groove, whereby the coiled roving is held in the
can against displacement, as described.
3. In a roving can, the combination with the open end of the can, of the open-
ings c, c, in the wall of the can below the edge surrounding the open end, and
a bar extending through the openings and across the can; whereby the roving :
is held in the compressed condition, as described.
