Our said invention relates to the application and use in a "Nobles" Comb or
other kindred combing machines of a "stop motion or self-acting apparatus for
stopping the combing machine when the sliver breaks, either when a lap forms on
the drawing off rollers or when the sliver adheres to and runs down the leather
and is prevented from passing to the can or any other receptacle, whereby damage
is done to the fibres and the progress of the work obstructed.
For this purpose on one of the spindles of each set of drawing off rollers and
near the bottom end, we secure a cam or tappet which revolves when the machine
is working and on the top of the cross rail of the combing machine we secure for
each set of drawing off rollers standards having guide openings formed in the
bottom parts of the foot plates through which passes and works for the forward
standard a bent lever or tongue formed on or connected to a long rod which
operates the slide bar and causes it to liberate a spiral spring and bring a finger in
contact with and actuate the strap fork and thereby throw the strap onto the loose
pulley thereby stopping the motion of the machine.
The standards are made with heads in which are secured studs on which are
hung weighted dropping levers having at their ends wedge shaped catches; the

page_text: sliver passes under the dropping levers and the tension holds the levers up and the
catches from contact with the revolving cains or tappets secured on the spindles of
the drawing off rollers
As soon as the fibres begin to lap on the roller or adhere to the leather the sliver
breaks and the tension being removed, the weighted dropping lever falls bringing
the wedge shaped catch in contact with the tongue or bent lever of the long rod
which pushes out the tongue or bent lever and liberates the rod from a notch made
in the slide bar which liberates the spiral spring fitted over the bar, bringing the
tongue secured onto the slide bar, in contact, and actuates the belt fork throwing
the strap onto the loose pulley thereby at once stopping the machine.
A rail is secured at a given height to the columns of the combing machine and
the rail is made with lugs between which works a boss formed on the long rod and
through the boss and lugs is passed a pin on which the long rod works. The slide
bar works through bearings secured to the columns of the combing machine so that
to set the machine at work, the operator pushes back or in the slide bar forcing in
the spiral spring which brings the long rod in gear in the notch and forces the
strap from the loose onto the fast pulley and the rod is kept in position in the
notch until a sliver breaks, by means of a spiral spring fitted to the head of the rod
-and-secured to the top frame of the machine. Should a sliver break at the back
drawing off rollers, the wedge-shaped catch of the dropping levers comes in contact
with the revolving cam or tappet and against the side of a lever which is connected
-to-other-levers-connected to the tongue of the long rod; the levers work on a stud
secured in the cross rail of the machine, when the back sliver breaks the tension
being removed the weighted lever falls and the catch actuates the levers forcing
- the rod from the notch of the slide bar and throws the belt or strap onto the loose
- pulley, as hereinbefore described,

The said invention relates to the application and use in a "Noble's " comb or
other kindred combing machines of a
stop motion or self-acting apparatus for
stopping the combing machine upon the breaking of the sliver, either through a lap
forming on the drawing off rollers or through the sliver adhering to and running
down the leather or through any other cause and being thereby prevented from
passing to the can or any other 'receptacle which breakage when the machine is not
stopped causes damage to the fibres and obstructs the progress of the work.
For this purpose on one of the spindles of each set of drawing off rollers and near
the bottom end we secure a cam or tappet which revolves when the machine is
working, and on the top of the cross rail of the combing machine we secure a stud
on which works the boss of a bent lever, one arm of the lever for each set of
drawing off rollers. On the end of each lever is secured in position a socket to
which is fixed a standard; on the top boss of the standard is fitted a stud on
which works the boss of a bent weighted lever having a wedge shaped catch; the
socket, coming in contact with a long rod, operates the slide bar and causes it to
liberate a spiral spring and to bring a finger in contact with and to actuate the
strap fork and thereby throw the strap onto the loose pulley, stopping the motion
of the machine. The standards are made with heads in which are secured studs on
which are hung weighted dropping levers having at their ends wedge shaped
catches the sliver passes under the dropping levers and the tension holds the
levers up and the catches from contact with the revolving cams or tappets secured
on the spindles of the drawing off rollers. As soon as the fibres begin to lap on
the roller or adhere to the leather the sliver breaks and the tension being removed,
the weighted dropping lever falls bringing the wedge shaped catch in contact
with the revolving cam or tappet which pushes out the bent lever and liberates the
rod from a notch made in the slide bar which liberates the spiral spring fitted over
the bar, bringing the finger secured on the slide bar in contact and actuating the
belt fork, throwing the strap onto the loose pulley and stopping the machine at
once. A rail is secured at a given height to the columns of the combing machine,
and the rail is made with lugs between which works a boss formed on the long
rod; through the boss and lugs is passed a pin on which the long rod works.
The slide bar works through bearings which are secured to the columns of the
combing machine so that, to set the machine at work, the operator pushes back or
in the slide bar forcing in the spiral spring which brings the long rod in gear in
the notch and forces the strap from the loose onto the fast pulley and the rod is
kept in position in the notch until a sliver breaks, by a spiral spring fitted to the
bead of the rod and secured to the top frame of the machine.
Should a sliver break at the back drawing off rollers, the wedge shaped catch of
the corresponding dropping levers comes in contact with its revolving cam or
tappet and against the side of a lever which is connected to other bent levers
thereby pushing out the long rod; the levers work on a stud secured in the cross
rail of the machine; when the back sliver breaks, the tension being removed, the
weighted lever falls and the catch actuates the lever thereby forcing the rod from

page_text: -
the notch of the slide bar and throwing the belt or strap onto the loose pulley as
hereinbefore described.
In order to enable our improvements to be fully understood we will proceed to
describe the same by reference to the accompanying drawing in which figure 1,
represents an elevation of part of a combing machine with our self acting apparatus
fitted thereto for stopping the combing machine when the sliver breaks. Figure 2,
is a side view and figure 3, a plan of the same. Similar letters of reference in all
the figures represent similar parts.
On the spindle A, of each of the drawing off rollers B, and near the bottom end
we secure the cam or tappet C, which revolves when the machine is working.
On the top of the cross rail D, of the combing machine we secure the stud E, on
which works the boss F of the bent lever G; on each end of the lever is secured in
position a socket H, to which is fixed a standard I; on the top boss of each standard
is fitted a stud J, on which works the boss K, of a bent weighted lever L, having a
wedge shaped catch M.-
The socket H, coming in contact with a long rod N, communicates to the rod a-
forward motion so as to remove the top of the rod from contact with the notch O,
cut in a sliding bar P, whereupon the bar is forced out by the spiral spring Q,
which is liberated and a finger R, is brought into contact with the strap fork S, and
the strap is thereby thrown from the fast pulley T, onto the loose pulley U,stopping
the motion of the machine.
The sliver V, passes under the dropping levers L, and the tension holds the levers
up and the catches M, from contact with the revolving cams or tappets C, secured
on the spindles of the drawing off rollers.
As soon as the fibres begin to lap on the roller or adhere to the leather the sliver
breaks and the tension being removed the weighted lever L, falls bringing one of
the wedge shaped catches M, in contact with the revolving cam or tappet C, which
pushes out the bent lever G, and liberates the rod N, from the notch made in the
slide bar P, and liberates the spiral spring Q, fitted over the bar and brings the
finger R, secured on the slide bar in contact with and thus actuates the bent fork S,
thereby throwing the strap from the fast pulley T, onto the loose pulley U, and
stopping the machine at once.
Between the columns W, of the combing machine and at a given height is fitted
a rail X, having lugs Z, between which works a boss A', formed on the long rod N, ;
through the boss and through the lugs is passed a pin B', on which the long rod N,
works. The slide bar P, works through bearings C', secured to the columns of the
combing machine.
To set the machine at work the operator pushes in the slide bar P, thereby
forcing in the spiral spring Q, and bringing the long rod N, into the notch and
forcing the strap from the loose pulley U, onto the fast pulley T; the rod N, is
kept in position in the notch O, until a sliver breaks, by the spiral spring D¹,
fitted over the head of the rod N, and secured to the top frame E', of the
machine.
Should a sliver break at the back drawing off rollers the other wedge shaped
catch M, of its dropping lever L, comes in contact with the revolving cam or
tappet C, and against a socket H, connected to the back bent lever G, pushing out
the long rod N, forcing the rod N, out of the notch; the sliding bar P, is then
actuated throwing the belt or strap from the fast pulley T, to the loose pulley U.
Having thus described our improvements and the best means we are acquainted
with for carrying the same into effect we would have it understood that we do not
confine ourselves to the precise details shown and described as they may be varied
without departing from the peculiar character of the invention but what we do
claim is
The construction and application to a " Noble's" comb or other kindred combing
machine of the herein described stop motion or self acting apparatus whereby the
stoppage of the combing machine is automatically effected upon the breakage of
the sliver through a lap forming on the drawing off rollers or through the sliver
E

page_text: adhering to and running down the leather or through any other cause the said
apparatus being constructed arranged and operating substantially in the manner
hereinbefore described and represented in the accompanying drawing.
In Witness whereof I the said Joseph Fawell for and on behalf of myself and
the said Jonathan Holden and James Burnley, have hereto set my hand and
seal this twenty eighth day of July in the year of our Lord, one thousand eight
hundred and eighty three
