PROVEMENTS IN THE METHOD OF AND APPARATUS FOR PREVENTING WASTE IN
ROVING AND SPINNING FRAMES."
The object of our Invention is to arrange a simple and effective apparatus that
can be applied to existing machinery, for the purpose of reducing the waste to a
minium, produced by the materials that are being operated upon by wrapping round
the front rollers.
We accomplish our object in the following manner:-To the framework of the
roving or spinning frame wo secure a metal bracket; the top part of this bracket
has a longitudinal slot hole which is placed near the front rollers and transversely
to the axis of the same; in this said slot hole we secure an easy fitting sliding block
that will slide from end to end of the said hole; to this sliding block is centred á
light lever, one end of which, called the front end, projects over the wire board, and
is bent in such a manner that the yarn passes over the end of the lever, and the
drag presses the same down to the wire board, the other end of the lever, called the
back end, is a little heavier, so that when the yarn breakes, or the pressure on thé
front end of the lever removed by the yarn snarling, the lever turns on its centre
or fulcrum, the front end lifting up, and the back end falling down. A projection
or stop is secured to this lever between its fulcrum and the front end, which comes
in contact (when the yarn is broken or slack) with a pin that is fixed in the side of
the front.rollers; this pin slides the lever and block back, and the back or heavy
"

page_text: end of the lever comes in contact and actuates a grooved lever. This last-named
lever is secured to a stud to which another lever is attached, which we call the cain
lever; this lever actuated in the mariner described, presses against a sliding cam,
and causes the end of the same to come in contact with another pin that is secured
in the side of the rollers of the machine; this pin slides the cam backwards
and actuates another lever which we call the tappet lever. This last-named lever
lifts a bar which is secured at one end, and grips the drawing or roving yarn and
prevents the same from travelling towards the front rollers of the machine, at the
same time this same tappet lever also lifts the back roller from the back fluted
roller and thus stops the drag on the roving, and prevents the drawing or roving
yarn running to waste.
When it is desired to set the back rollers in motion and piece up the broken yarn,
the attendant releases the sliding cam by means of a lever which projects over the
wire board, when the drawing or roving yarn will travel and feed the front rollers
as before.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Richard Varley, John Procter Wolfenden, and Sylvester Scaife in the
Great Seal Patent Office on the 19th December 1877.

and SYLVESTER SCAIFE, Mechanic, all of Keighley, in the County of York. "IM-
PROVEMENTS IN THE METHOD OF AND APPARATUS FOR PREVENTING WASTE IN
ROVING AND SPINNING FRAMES."
The object of our Invention is to arrange a simple and effective apparatus that
can be applied to existing machinery, for the purpose of reducing the waste to a
minimum, produced by the materials that are being operated upon by wrapping
round the front rollers.
We accomplish our object in the following manner: To the framework of the
roving or spinning frame we secure a metal bracket; the top part of this bracket
has a longitudinal slot hole which is placed near the front rollers and transversely
to the axis of the same; in this said slot hole we secure an easy fitting sliding block
that will slide from end to end of the said hole; to this sliding block is centred a
light lever, one end of which, called the front end, projects over the fly board, and is
bent in such a manner that the yarn passes over the end of the lever, and the drag
presses the same down to the fly board; the other end of the lever, called the back
end, is a little heavier, so that when the yarn breakes, or the pressure on the front
end of the lever removed by the yarn snarling, the lever turns on its centre or
fulcrum, the front end lifting up, and the back end falling down. A projection or
stóp is secured to this lever between its fulcrum and the front end, which comes in
contact (when the yarn is broken or slack) with a pin that is fixed in the side of
the front rollers; this pin slides the lever and block back, and the back or heavy
end of the lever comes in contact and actuates a grooved lever. This last named
lever is secured to a stud to which another lever is attached, which we call the cam
lever; or the grooved lever may be extended at the bottom end and thus form the
cam and grooved lever combined. The cam lever being actuated by the first.
named lever in the manner described; presses against a sliding. cam and causes the

page_text: end of the same to come in contact with another pin that is secured in the side of
the front rollers of the machine; this pin slides the cam plate backwards, and
actuates another lever which we call the tappet lever. This last-named lever lifts
a bar which is secured at one end near the roving and grips the drawing or roving
yarn, and prevents the same from travelling towards the front rollers of the
machine; at the same time this said tappet lever also lifts the back roller from the
back fluted roller, and thus stops the drag on the roving, and prevents the drawing
or roving yarn running to waste.
When it is desired to set the back roller or rollers in motion and piece up the
broken yarn, the attendant releases the sliding cam by means of a lever which
projects over the fly board, when the drawing or roving yarn will travel and feed
the front rollers as before.
In order that our Invention may be more clearly understood, we have hereunto
annexed Drawings which illustrate such portions of a spinning frame as are required
to shew the action of our Invention.
Figure 1 represents a section through the top portion of a spinning frame which
is fitted with our improvements.
Figure 2 is a plan of our improvement.
Figure 3 is an enlarged view of the back roller of the spinning frame.
Figure 4 is the side elevation of the back roller, which also shews the projection
and adjustable block for gripping the yarn.
Figure 5 is a plan of the roving and ordinary back rollers which can also be used
in combination with our improvement.
Like parts in the Drawings are indicated by like letters and figures.
The portion marked by the letter A is part of the framework of an ordinary
spinning frame; B is the fly board rail to which is secured the fly board B¹ in the
usual manner. The front roller C and the top front roller C³ are mounted in
journals in the ordinary manner; D is a bracket that is secured to the fly board
rail B. At the top of this bracket at D¹ is formed a groove, in which is fitted the
sliding block E, which has a projecting stud that forms the fulcrum of the light
lever F. The front end of this lever is bent at F¹ and projects in a longitudinal
direction over the fly board. The yarn G which passes between the rollers C and C¹,
is passed over the end of lever at F to the bottom on the spindle, and thus the
drag of the yarn keeps the projecting end of lever near to the fly board. When the
yarn G breaks, or the pressure on the projecting end F¹ is removed through any
cause, the back end of lever F at F, which is a little heavier than the front end,
will descend, and in so doing the front end will be elevated or lifted up towards
the axis of the front rollers, when the pin H, which is secured in the side of
roller C, and projects therefrom, will come in contact with projection J secured to
lever F, and thus cause the lever F and block E to slide back from the front of the
frame. The end F will come in contact with the hollow or grooved lever K, which
is centred on a stud secured to bracket D. The bottom part of this lever at K¹ is
what we call the cam lever, and is formed wedge shape, and by the actuation of
this lever in the manner described the cam end K¹ will come in contact with the
cam plate L and move the same sideways towards the front roller C, when the
pin H, which is also secured to the side of front roller C, and projects therefrom,
will come in contact with the stop or projection L, and thus by these means the
cam plate L will slide back from the front of the frame, and by so doing will
actuate the lever M, which is centred in the projections D², and cause the circular
end of the lever M at M to raise the bar N, which is centred at the top end in
joint N, to the roving board or plate A³.
The back roller rails, the top parts of which are shewn more clearly in the
enlarged Drawing in Figure 3, are secured to the framework in the ordinary manner,
the top parts of which at O' are arranged with flanges, to which is secured the
cross bar 0%. Through this bar is fitted the screw Os, by which means pressure is
applied to the top back roller O' through the bottom cross bar, and spiral springs
fixed at each side of the pulley. On to the axis of the top roller O' at each side of

page_text: the same is placed a plate 05 which rests in the recesses formed between the fluted
portions of the back bottom rollers T. The projections P on plates 05 are fitted
with a block P¹ between the same, which is capable of being regulated by means of
the screw P. At the under side of block Pf is a pin Q which passes through
stay Q the bottom end of this pin rests upon the top side of bar N. The top of
the pin Q is formed with a head of large surface. When the bar N is lifted as before
described, the pin Q will be raised also; and will compress the roving yarn R that
passes through the guard S between the head of the pin and the adjustable block P',
and thus grip the yarn tight, at the same time the top back roller 04 will be
elevated from the fluted roller T; and thus the drag of yarn from the roving U is
suspended until such times as the operator or attendant releases the same, which is
accomplished by means of the lever V, which is centred on plate L. By actuating
this lever,. the same will move the cam plate (which is held in position by means of
a pin) sideway until the stop or projection L' is out of line with the projecting
pin H¹, when the weight of the bar N will force. the cam plate back into its original
position, where it will remain until such times as the pressure is removed from the
projecting end of lever F.
When it is desired to remove the bobbins that are full of yarn from off the
spindles, the front end of the lever. F, which is arranged with a joint at F', can be
lifted up towards-the-front. rollers, when the fly board can. also be lifted and the
bobbins placed on or removed from the spindles. On the fly board B' and the
jointed end of lever F being put back into their original positions, the machine can
be again set in motion.
Having now. described our Invention and the manner in which the same is or
may be performed, we have to state that we do not restrict ourselves to the precise
details herein. described and delineated, but that what we believe to be novel and
original, and claim as the.Invention secured to us by the herein-before in part
recited Letters Patent is,-
The arrangement and combination of the various parts for gripping the roving
yarn in its transit from the roving bobbin to the front rollers, substantially as
herein-before described and illustrated on the accompanying Drawings.
The arrangement and combination of the various parts for lifting the top back
roller from off the bottom fluted roller, substantially as herein-before described and
illustrated on the accompanying Drawings.
In witness whereof, I, the said Richard Varley, of and on behalf of myself
and the said John Procter Wolfenden, and Sylvester Scaife, have hereunto
set my hand and seal, this Seventeenth day of December, in the year of
our Lord One thousand eight hundred and seventy-seven.
