This invention relates to machines employed for sizing yarn and consists.
Firstly Of an improved friction motion for the unsized Yarn beam.
Secondly Improvements in the Markers or apparatus employed for marking the
cuts of the yarn.
means.
The friction motion comprises two concave plates or discs one of which is driven
and having studs attached thereto the stud impart motion to an internal carrier
wheel the teeth of which gear with internal teeth on the rim of the second plite
or disc whereby the latter is caused to rotate loosely on its shaft. On the main
Axis or shaft carrying the plates is a friction pinion gearing with a carrier (or
carrier wheels) the friction pinion being between the said wheels and is gripped
through the agency of plates or clutch box actuated by levers weights screws or
springs the said friction wheel being released at will ensures a differential motion
being given to the Yarn beam-A modification of the above comprises like stud
wheels internal gear the friction or brake wheel having on its boss a pinion gearing
with the internal wheel and friction is applied to the brake wheel by strap or other
It will be understood that the levers above mentioned are levers which are
used to carry the tension roller, which roller in machines of this character, as
ordinarily constructed is supported in ordinary fixed bearings, but by supporting
the roller upon levers as we propose the roller is made as hereinafter more fully
described to serve an additional purpose of nipping as well as the purpose of
guiding the yarns in the ordinary way. The marking apparatus may be driven as
hereinafter described direct from the worm shaft by stud and carrier wheel and on
the stud is a pinion change wheel gearing with largo spur wheel on axis of which
is placed the general change wheel the latter gears with and drives a wheel on the
Axis of the Cam for operating the hammers both of which operate on one bowl
and so arranged as to strike proximately the same line of threads the hammers are
carried on one shaft but their heads are so arranged as to be in one line the said
lammers are adjustable so as to strike on any part of the width of the warp the
latter being supported during the action of the hammers on bowls or runners
under and at right angles to the Yarn so that the threads make equal and but
slight deviation froin their line of transit during the operation of Marking whereby
accuracy is ensured.
Such being the nature and object of this our said invention we will now proceed
to describe the same in detail and in order that the invention may be clearly
understood we have Annexed 5 sheets of drawings and have Marked the same
with figures and letters of reference.
DESCRIPTION OF THE DRAWINGS.
Figs. 1 to 5 illustrate the improved friction Motion for the warp beam and
several modifications of such improved friction Motion.
Referring now to Fig. 1 whereby is shewn friction apparatus drawn about
half size.
At 1 and, 2, are two plates or discs, the plate 1, being on the shaft 3, and the

page_text: Jatter is driven thereby, at 4 is a stud, bolted to plate 1, and caused to revolve
along with the said plate, the pinion wheel 5, on the stud 4, gears with the internal
teeth 6, formed within, and around the inner rim 7, of the plate or disc 2, and with
the teeth of the friction pinion 8, on the shaft 3. The plate or disc 2, is thus caused
to revolve, but being loose on its shaft 3, will "lag," so as to compensate, for the
changing diameter of the weavers beam, as the Yarn is wound thereon. At 9. 9.
are washers or packing rings of Bannel,-10 is a counter balance weight, carried
on stud 11, and at 13 is a roller, carried on lever 14, having its fulcrum on
shaft 15.
The roller 13 when in its highest position, (see Fig 2) acts as a tension roller,
and when in its lower position, it is made to nip the yarn, against the lag roller 16,
and hold the Yarn securely, whilst the latter is being cut, and the full beam 17
removed, at 18, is a balance weight, and 19 is a weighted lever, which bears against
the bar 20, so as to steady the latter, and prevent vibration. At 27 Fig. 1 is a
cranked arm or lever, connected with tho half 28, of the clutch 29, the weight 18,
on lever 14, forces the clutch 28, against its corresponding half 29, forcing against
boss 30, of wheel 2, keeping the friction plates 1. 2 up to tho flannel washers 9.
As the Yarn passes over the roller 13, it in part takes off the weight, and adjusts
the pressure of clutch 28, on the boss 2, of the friction plates. At 21. 22. 23.
and 24 (Fig. 2) are the parts constituting the brake and weight regulating
apparatus, at 25. 26, is the handle, & holding catch, by means of which the
"sizer" can force down the lever 14, and the nip roller, whenever desirable or
necessary.
Fig 3 is enlarged view, about full size, of frictional apparatus being a modifi-
cation of Fig. 1. At 1 is the shaft, on which is the disc or plate wheel 2, carrying
stud and pinion 3, the latter gears with the internal teeth 4, of plate wheel 5, and
with pinion 6, on long bush 7, on which is (the brake wheel 8, the teeth 9 of spur
wheel 5, gear with, and drive wheel on axis of warp beam-the brake wheel 8, is
held by brake strap, or other like contrivance, as illustrated in Fig 2, by levers
as nt 21, 22-23-nnd 24.
Another modification comprises (Figs 4-5) a pinion wheel 1, on driving shaft 2,
at 3 is an intermediate or carrier wheel, gearing with plate wheel 4, free to slide on
key of its shaft 5-, at 6 is a like wheel, loose on the shaft 5, thero being flannel
packing or ring 7, between the two, at 8 is a plate, fast on and driven by the
shaft 5, and having flannel packing 9, the wheel Gloose on shaft 5, is the driver,
of the wheel 10, which is on the axis of the weavers beam 11-the wheel 6 being
free to slip or "lag," so as to compensate for filling of beam, as described, and like
apparatus for forcing up the friction clutch and boss 11, as described and illustrated
by Fig 1.
Referring now to Figs 6, and 7, whereby is illustrated the marking apparatus-
At 1 is the worm shaft, 2 a pinion wheel, on the said shaft, and genring with the
carrier wheel 3, mounted on the stud 4, on the latter is a pinion wheel 5, (5ª on
same boss is used as a change pinion) gearing with stud wheel 6, on the same stud
is the pinion 7, gearing with the wheel 8, which drives the cam 9-at 10, and 11,
are the hammers, under which are the pulleys, 12. 13, the Yarn being above the
periphery of the said colour bowls, or pulleys 12. 13, when being marked, by the
hammers 10. 11-At 14 is the hammer shaft, along which the bosses of and
hammers may be slided, so as to mark the yarn where required. At 15 is a cam,
on the bell shaft 16, driven by worm 17, imparting by means of lever and
boss 19, and shaft 20, motion to the hammer 10. The hammer 11, being operated
in like manner from the cam 9 lever 9-and shaft 14, each hammer having
independent motion and action
At Figs 8 and 9 is shewn elevation, and plan, of marking apparatus, the
hammers 12, arc by means of cranking their stems 3. 4, so arranged, as to strike
and mark, on one and the same traverse line, of the Yarn-the colour bowl, being
placed at right angles to the Yarn.

page_text: Having thos fully describe.), the nature of our said invention, and in what
manner the same is to be performed, we claim;
Firstly The combination of parts, constituting the improved friction clutch
apparatus, illustrated by Figs: 1. 2. 3. 4. 5 of the annexed drawings.

in inanner described, and illustrated by the annexed drawings, so as to serve the
double purpose, of guiding the yarn, and nipping and holding the same, securely,
when required.
Thirdly The combination of the tension and nipping roller, and the carrying
levers, with the lag roller, and clutch apparatus, substantially in the manner, and
for the purpose, substantially as described
Lastly The improved marking apparatus, operated by means, described, and
illustrated by the annexed drawings.
In Witness whereof I the said Alfred Hitchen [sic] for and on behalf of myself
and the said Edmund Tweedale have hereunto set my hand and seal this
nineteenth day of July in the Year of our Lord one thousand eight hundred
and eighty-three
