I WILLIAM LANCASTER of Willow Iron Works, Accrington in the County of
Lancaster, Machine Maker, do hereby declare the nature of the said invention to be
as follows:-
This invention relates to improvements in machinery for purpose aforesaid, and the
object is to provide a uniform predetermined amount of pressure or weight on
the frictional motion. To provide for the automatic throwing in and out the gear for
driving the nip roller. To provide means whereby the drum and beam may by hand,
be turned as required, with less labour, and to ensure its free rotation generally-
and. To automatic apparatus which at any predetermined number of revolutions of
the drum, and warp beam, or length of warp, will stop the machine.
According to this my said invention in connection with the frictional clutch driving
mechanism I employ a lever and adjustable weight-the inner end of the lever is
connected to the side arm of the treadle lever so that when the machine "knocks
off" the treadle lever ascends, and a finger is brought under and in contact with the
weighting lever which it lifts, and so seperates the clutch.
On restarting the machine the attendant depresses the treadle lever as ordinary-
such movement carries the finger from under the side arm of the treadle, whereon the
weighted lever brings the clutches together-and there is no weight or pressure on
the friction, other than that provided for by the weight and lever. The gear for driving
the nip rollers consists of a gear wheel and a chain wheel, these are carried on a stud,
attached to a pendant arm, in contact with which is an adjustable presser finger,
connected with the side arm of the treadle lever. On the axis of one of the nip
rollers, is a chain pulley over which the chain from the chain wheel referred to,
passes. When the treadle is depressed, to start the machine, the presser finger on
the side arm of the treadle, is, by motion of said arm, caused to bear on and against
the pendant arm, which it presses forwards, and so brings the gear wheel into gear
with the driving wheel of the friction shaft.
When the machine "knocks off" or stops the treadle is raised by its balance
weight as ordinary and the pendant is by a shoulder of the finger first mentioned,

page_text: forced back moving the gear and chain wheel back and clear of the driving wheel,
whereon the drum is quite free, and may be turned by hand, in either direction at
will.
For facilitating the turning by hand, and the driving generally of the drum, I
mount the axle or shaft upon anti friction pulleys carried in an oil or lubricating box
affixed to the side frame of the machine these are employed in combination with
brackets, and caps which secure the shaft in position.
For purpose of stopping the machine at any given number of revolutions of the
drum and beam that is to say, at any given length of yarn wound on the beam I
employ wheels or discs having catches and nugs in connection with the stopping or
knocking off" mechanism, the first wheel is operated by a worm on the shaft of the
measuring roller or from any convenient going part of the machine, and in turn
operates a second wheel or disc by means of a nug operating on a catch on the
second wheel this take place when the first wheel or disc has made, say, one revolution,
and so one the last wheel or disc has a finger working in connection with the stopping
mechanism, and "knocks off" at any predetermined length of yarn wound on the
beam according to the number of wheels or discs, or according to the number of
teeth on such wheels, or to the number of nugs & catches.

I, WILLIAM LANCASTER of Willow Iron Works, Accrington in the County of
Lancaster, Machine Maker 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 :-
This invention relates to improvements in machinery for purpose aforesaid, and the
object is to provide a uniform pre-determined amount of pressure or weight on the
frictional motion. To provide for the automatic throwing in and out the gear, for
driving the nip roller. To provide means whereby the drum and beam may by hand
be turned as required with less labour, and to ensure its free rotation generally-and
To automatic apparatus which at any pre-determined number of revolutions of the
drum and warp beam or length of warp will stop the machine.
According to this my said invention in connection with the frictional clutch driving
mechanism, I employ a lever, and adjustable weight-the inner end of the lever, is
connected to the side arm of the treadle lever, so that when the machine "knocks off"
the treadle lever ascends, and the finger referred to is brought under and in contact
with the weighting lever which it lifts, and so separates the clutch.
On re-starting the machine, the attendant depresses the treadle lever as ordinary-
such movement carries the finger from under the side arm of the treadle whereon the
weighted lever brings the clutches together-and there is no weight or pressure on
the friction other than that provided for by the weight and lever.
The gear for driving the nip rollers consists of a gear wheel and a chain wheel,
these are carried on a stud attached to a pendant arm, in contact with which is an
adjustable presser finger connected with the side arm of the treadle lever.
On the axis of one of the nip rollers is a chain pulley, over which the chain from
the chain wheel referred to passes.
When the treadle is depressed, to start the machine, the presser finger on the side
arm of the treadle, is-by motion of said arm, caused to bear on, and against the
pendant arm, which it presses forwards, and so brings the gear wheel into gear with
the driving wheel of the friction shaft.
When the machine "knocks off" or stops, the treadle is raised by its balance
weight as ordinary, and the pendant is, by a shoulder of the finger first mentioned,
forced back, moving the gear and chain wheels back and clear of the driving wheel,
whereon the drum is quite free, and may be turned by hand in either direction at will.
For facilitating the turning by hand and the driving generally of the drum I
mount the axle or shaft upon anti-friction pulleys carried in an oil or lubricating box
affixed to the side frame of the machine these are employed in combination with
brackets and caps which secure the shaft in position.
For purpose of stopping the machine at any given number of revolutions of the
drum and beam that is to say-at any given length of yarn, wound on the beam, I
employ wheels, catches, and rings in connection with the stopping or "knocking off
mechanism, and operated from any convenient going part of the machine.
"
Such being the nature and object of this my said Invention, the following is a
complete desciption of same, reference being had to the accompanying drawings.

work.

turned by hand.
Fig. 3 is a front elevation of above.
Fig. 4 shews application of invention to machines wherein friction plates are
employed in lieu of gear wheels for driving chain wheel and the nip rollers.
Fig. 5 is a side elevation of Fig. 4.

Fig. 7 is a side elevation of Fig. 6.
Fig. 8 is an elevation of like disc made in two parts.
Fig. 9 is edge view of said wheel, also end view of driving worm.
At 1 is the ordinary clutch from which extends the lever 2 carrying the adjustable
weight 3.
At 4 is a pin projecting from the weight.
5 is a lever working on stud 6, its other end is slotted and connected by link 7 with
the treadle lever 8, on fulcrum at 9.
At 10 is presser finger, attached to the side arm of the treadle lever 8, and which
finger, when the treadle is down, (as shewn in Fig. 1) and the machine at work,
bears against the pendant arm 11, free to swing, from the stud 12, and keeps the
wheel 13, so long as the treadle is down, in gear with the wheel 14, driven by the
pulley 15. 16 is the chain wheel, 17 the chain, and 18 the driven nip roller.
When the machine "knocks off," the weight 19, depresses the end 20, of the
treadle lever 8, the link 7, turns the lever 5, on its fulcrum pin 6, the other, and
curved end of the lever 5, engages with the pin 4, attached to the weight 3, which it
lifts and by the movement of the lever 2, separates the clutch 1, to loose half of which
lever 2 is attached meanwhile, and simultaneously with separation of the clutch, the
upward movement of the arm 21, of lever 8, will have carried the presser finger 10,
backwards, and the pendant arm 11, will then be free to swing on the pin 12,
carrying the wheels 13, 16, with it, thus separating the gear 13-14 (see Fig. 2) and
leaving the pulley, and beam, quite free, that the latter may, with ease be then turned
by hand.
The depressing the treadle, automatically returns, all the parts to their working
position, as shewn at Fig. 1.
The weight 3, on the lever 2, not only gives, when set, an unvarying pressure on
the friction clutches 1, but by adjusting the weight 3, on the said lever, the frictional
contact of the clutch 1, may be regulated as desirable.
Where in lieu of the gear wheels 13-14, for driving the chain wheel 16, and nip
rollers 18, a friction pulley 15, and plate 15, are employed, (see Figs. 4, 5) the lever
arm 2, of the friction 1, is connected to treadle 8, so that when the latter is depressed,
the inclined surfaces of the friction 1, are by the lover arm 2, brought into contact,
and part 1 also slides the chain wheel 16, and friction pulley 15 on the shaft 16°, into
contact with the outer plate 15, of the pulley, the plate 15 becomes the driver being
keyed fast on the shaft 16, and the nip roller 18 is thus driven, the axle of nip
roller 19, is carried on inclined plates 19ª, which ensures the rollers coming together.
When the machine "knocks off," the levers, 8, and 2, through the action of the
weight 3, separate the friction 1, and the contact, and driving surfaces 30—30, the
driver 15, is then free to be turned by hand.
The automatic mechanism, for stopping the machine, soon as the required length
has run on to the beam, consists of three discs, or star wheel motion.
The disc 22, is cast to the worm wheel 23, of 100 teeth, which gears in the
worm 24, of the measuring roller 25, the circumference of the measuring roller, is
half a yard, therefore when the said roller, has made 100 revolutions, the disc 22, will
have made one turn, and will indicate 50 yards.

page_text: The disc 26, slides on the ring 22 of the worm wheel 23, till the stud or pivot 27,
comes into the recess, and turns the disc 26, therefore when the disc 22, has made ten
revolutions, the disc 26 has made one revolution, and will indicate 500 yards.
The same process continues, with the discs 28, or any required number of such discs.
When the disc 26 turns once round, the pivot 29, of discs 26, moves the disc 28,
one tenth part of its circumference, and when the disc 26, turns ten times round, the
disc 28, will have made one revolution, and indicated 5000 yards.
So that when the measuring roller makes 10,000 turns, the disc 23 makes
100 revolutions, and the disc 26, 10 revolutions, the disc 28 one revolution, and
indicates 5000 yards, and the finger 31 presses against the lever 32, which hangs on
the bracket 33, on a little snug and it falls by the weight, and stops the machine by
relieving the driving friction on drum shaft.
To reset the dials, they are successively raised on their carrying studs 34, clear or
out of gear with each other, and turned back to required position, in relation to the
pointers 35, and it will be understood, that just as the finger 31, is to "knock off," at
less than 5,000, so will the said finger, be started at a point, so as to make a portion
of a revolution, corresponding to the length to be wound, before the finger reaches
the lever 32, and "knocks off," or the disc wheel 34, may be made in two
segments 36. 37, one being behind the other, and capable of being moved radially, and
fixed by the bolts 38, in the radius slots 39, so that the worm 40, which is set over the
wheel, so as to engage with the teeth of either segment, and will drive the wheel,
until the pin 47, comes in contact with the "knocking off" lever 42, and forces the
latter, off its supporting bar 43, and the machine is stopped, the segments being
subdivided, and figured, forming a dial, and as more or less of the entire circle of
teeth, are employed, so will the machine "knock off," at greater or less length of
yarn wound on the beam.
The mechanism described, dispenses with the use of the clock indicator, and the
warp motion heretofore, usually employed on machines for purpose aforesaid.
Having now particularly described and. ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what I
claim is :-
Firstly. The mechanism for applying an uniform and pre-determined weight, or
lateral pressure, on the movable part of the friction 1, combined with the appliances,
whereby such pressure is automatically removed, when the machine "knocks off," as
illustrated and herein described.
Secondly. The gear and chain wheels 13, 16, a pendant or swinging carrier such
as 11, operated by finger or projection, such as 10, through the movement of the
treadle 8, all in combination, and for purpose described and illustrated by drawings.
Thirdly. The combination of parts comprising friction 1, weighted lever 2,
automatically separated through the action of the treadle lever 8, link 7, and lever 5,
when the machine "knocks off"-the parts resuming their working position auto-
matically soon as the treadle is depressed, as herein described and illustrated by
annexed drawings.
Fourthly. The discs or star wheel motion, indicating dials, and finger operated
from the measuring roller, all in combination and for purpose described.
Fifthly. The friction 1, lever 2, combined with the weighted lever 8, for operating
the chain wheel 16, and pulley 15, as described in relation to, and illustrated by
Figs. 5 and 6 of the drawings annexed.
