IN ROVING AND SPINNING FRAMES."

"IMPROVEMENTS
IN APPARATUS FOR PREVENTING WASTE IN ROVING AND SPINNING FRAMES."
My Invention relates to employing a simple and effective apparatus which can be
applied to existing spinning frames for the purpose of stopping the roving on the
breakage or slackness of the same, preventing loss by waste, roller lapping, snarls,.
and doubles.
For this purpose I fit in any convenient position between the roving bobbins and
front rollers a rail or support, on which I secure a bracket in which works a small
spindle; upon this spindle is fixed a wharle which actuates the spindle, and the
wharle is worked by a band which is actuated by another wharle fitted upon a shaft
or cylinder extending the length of the spinning frame, or the wharle can be actuated
by gear; an apparatus is fitted to each spindle of the spinning frame. Upon the
spindle I secure a small cylinder, around which the roving runs in a spiral to give
tension and to further increase the tension if the increase of tension is required. I
fit on the side of the cylinder eyes or guides formed on wires, which are fitted in a
suitable bearer; the roving coming from the roving bobbin is passed through one or
more of these eyes or guides according to the required tension. The roving passes
from the eye or eyes to the cylinder, and is wrapped two or three times spirally
round the cylinder, according also to the required tension. The roving passes from
the cylinder to the front rollers, and from there, through an eye of a centred light
Price dı

page_text: lever or wire, to the flyer or the cap of a cap spinning frame. The drag of the
roving when spinning presses down the eye of the centred light lever and arm,
lifting up the other arm of the lever; but should the roving break or become slack,
and the pressure on the eye removed, the lever, turning on its fulcrum, lifts up the
arm having an eye and lowers the other arm, and on the end of this arm are fitted
studs or projections which come in contact, when lowered, with pegs or projections
fitted or cast on the top of the spinning wharle, stopping the spindle and cylinder,
and consequently the delivery of the roving. The light lever is fitted in a sliding
bearer, and with a movable balance weight to regulate the position of the lever
according to requirements.
By these means I prevent waste, roller lapping, snarls, and doubles.

HENRY AMBLER, of Halifax, in the County of York, Spinner. "IMPROVEMENTS
IN APPARATUS FOR PREVENTING WASTE IN ROVING AND SPINNING FRAMES."
The said Invention relates to employing a simple-and effective apparatus which
can be applied to existing spinning frames for the purpose of stopping the roving on
the breakage or slackening of the same, thereby preventing loss by waste, roller
lapping, snarles, and doubles.
For this purpose I fit in any suitable position between the roving bobbins and
the front rollers a rail or support, on which I secure a bracket in which works a
small spindle; upon this spindle is fixed a wharle which actuates the spindle, and
the wharle is worked by a band which is actuated by a cylinder extending the
length of the spinning frame, or the wharle may be actuated by gear; an apparatus
is fitted to each spindle of the spinning frame.
Upon the spindle I secure a small cylinder, around which the roving runs in a
spiral form to give tension; and to further increase the tension, if increase of tension
is required, I fit on the side of the cylinder eyes or guides formed on wires which
are fitted in a suitable bearer. The roving coming from the roving bobbin is passed
through one or more of these eyes or guides, according to the tension required. The
roving passes from the eye or eyes to the cylinder, and is wrapped once or twice
spirally round the cylinder, according also to the tension required. The roving
passes from the cylinder to the front rollers, and from thence through the bent end
of a light centred lever wire to the flyer or the cap of a cap spinning frame. The
drag of the roving when spinning presses down the bent end of the light centred
wire, lifting up the other arm of the lever; but should the roving break or become
slack, and the pressure on the bent end of the wire be removed, the wire lever,
turning on its fulcrum, will lift up the wire having the bent end and lower the other
arm, and on the end of this arm are fitted pins which come in contact, when lowered,
with pins or projections fitted or cast on the top of the spindle wharle, stopping the
spindle and cylinder, and consequently the delivery of the roving. The light lever
is fitted in a sliding bearer, and is provided with a moveable balance weight to
regulate the position of the lever according to requirement.
By these means I prevent waste, roller lapping, snarles, and doubles.
But in order to enable my improvements to be better understood I will proceed
to describe the same by reference to the accompanying Drawing, in which Figure 1
represents a side elevation of my improvements and such portions of the spinning
frame as are required to shew the action of the Invention; Figure 2 represents a
top view of the wharle of the small-spindle ;-and Figure 3 is a plan of the small
cylinder shewing the position of the guides for increasing the tension.
A is the rail or support, extending the length of the spinning frame, and in which
are fitted bushes B in which work small spindles C, one for each flyer or cap spindle,
and this spindle also works in a bush fitted in a rail D which is secured to and
extends the length of the spinning frame; on the spindle C is fitted a wharle E
which actuates the spindle, and which receives motion by a band F, which is driven
by a cylinder G extending the length of the spinning frame, but the wharle may be.
driven by gear.
Upon the top of the spindle C I fit a small cylinder H, round which the roving I
runs spirally to give tension, and if it is required to increase the tension I pass the
roving through eyes or twizzles J and K, and also through a guide L. A. guide L is
fitted to each small spindle, and they are secured to a bar M which extends the
length of the spinning frame. The bar works the guides L to and fro, guiding the

page_text: roving, and the to and fro motion is communicated by a worm and worm wheel
which are actuated by a band which is driven by the back cylinder G.
The roving passing from the small cylinder H travels on through the rollers N to
-the front rollers O; and then over the bent wire P of a centred wire lever Q, and
from thence to the flyer or cap. The drag of the thread in the process of spinning
presses down the bent wire P and lever Q, and lifts up and out of gear the arm R,
in which are fitted pins S; the arm R is fitted with a moveable weight T to allow
'the working of the levers to be regulated to a nicety.
Should the roving or thread break or become slack, and the pressure on the bent
wire P and lever be thereby removed, the lever Q, turning on its fulcrum, will lift
fup and lower the arm R, and bring the pins S in contact with one or more pins or
projections U.fitted or cast on the top of the wharle E, which will stop the revolving
of the wharle, and consequently the spindle C and the top cylinder H, and thereby
the delivery of the roving will be stopped. The levers Q and arm Rare fitted in a
socket V which works on a pin fitted in a bracket W, which is secured to a rail X
extending the length of the spinning frame,
Having thus described my improvements and the best means I am acquainted
witli for carrying the same into effect, I would have it understood that I do not
confine myself to the precise details shewn and described, as they inay be varied
without departing from the peculiar character of my Invention; but what I do
claim is,
The arrangement, combination, and employment of the various parts for stopping
the roving or thread on the breakage or slackening of the same, substantially as
and for the purpose hereinbefore described and illustrated in the accompanying
Drawing.
