MACHINERY OR APPARATUS FOR WINDING TWO OR MORE YARNS OR THREADS
OF COTTON AND OTHER FIBROUS MATERIALS ON TO ONE BOBBIN OR SPOOL."
Our improvements relate to that class of machinery known as "winding frames"
and consist firstly in an arrangement for arresting the motion of the bobbin when
one or more of the yarns or threads that are being wound become or becomes
broken or severed.
For the above purpose wo cause the yarns or threads whilst passing from the
cop, bobbin, or spool to the bobbin, upon which they are to be wound; to pass
through and support eyes or loops formed of wires or plates; which eyes or loops
are carried in a frame provided with projections for keeping the eyes or loops in
proper working position, and also to allow them to be moved and supported as
hereafter to be described. This frame is carried in a bracket attached to the
frame-work of the machine, which bracket also supports an oscillating plate which
is provided with slots for the above named projections to pass through, and the said
plate is also for the purpose of keeping the above named eyes or loops in working
position.
Beneath the above mentioned eyes or loops is an arm or lever to which a
vibratory or oscillating motion is imparted. This arm or lever is free to pass under
the above mentioned frame and oscillating plate. One end of the oscillating plate
is formed so as to receive a projecting part or catch formed on a handle or rod
capable of sliding through a bracket carried by the framework of the machine.
The above mentioned handle or rod is jointed to one end of a weighted lever
turning upon a rod attached to the framework of the machine, the other end of the
said lever projecting beneath a rod sliding in guides carried by the framework
before named. The before named sliding rod is provided with or has formed at its
upper end a plate or break, such plate or break, when raised as will be hereafter
described will act upon the bobbin upon which the yarn is to be wound so as to
''

page_text: remove it out of contact with the drum by which it is rotated for the winding on
of the yarns or threads. The aforesaid bobbin is carried upon a spindle mounted
in a cradle supported by rods or guides attached thereto which slide within
openings formed within the framework aforesaid.
So long as the previously mentioned eyes or loops are supported by the yarns
or threads, the above named vibrating arın or lever passes freely under the above
named frame and oscillating plate, but upon any of the yarns or threads breaking,
the eyes or loops being no longer held in position are allowed to fall within the
path of the vibrating arm or lever before named, which latter carries the eyes or
loops before it bringing them in contact with the before named oscillating plate,
thereby causing it to become turned upon its centre as will be hereinafter described.
The eyes or loops having been carried forward as above described are retained in
such position by means of the projections upon which they move or slide, such
projections being provided in the before named frame for the above purpose,
and are so kept clear of the vibrating arm or lever as long as may be necessary.
When the above named oscillating plate has become turned upon its centre, a
projecting part thereof acts against the before named handle or rod and pushes
it forward thereby liberating the catch formed thereon from the part supporting
it so as to allow it to be drawn down by means of the before named weighted lever
which acting upon the before named handle or rod carrying the plate or break,
lifts the bobbin by means of this break clear of the drum from which it receives
motion, thereby arresting the winding-on of the yarn.
To facilitate the piecing of the yarn or threads the before-named cradle carrying
the bobbin upon which the yarns or threads are being wound may be still further
raised by hand, until its previously named rods or guides allow a projecting part
upon the weighted lever before named to pass underneath and support them.
After the yarns or threads have been pieced the previously named handle or rod
provided with a catch is drawn upward-so-that-the-said-catch-may rest upon the
oscillating plate before named carried by the bracket attached to the framework
of the machine, which bracket also carries the before named frame containing the
previously mentioned eyes or loops. Such drawing up of the above named handle
or rod allows the bobbin to pass into contact with the winding on drum, at the
same time the above named oscillating plate coming in contact with the aforesaid
eyes or loops restores them to their proper working position; and the bobbin as
before described coming against the circumference of the winding on drum, the
winding on the yarns or threads is again proceeded with.
The second part of our Invention consists in improvements particularly appli-
cable to winding yarns or threads from one set of spools or bobbins on to another
bobbin or tube; and where the bobbins or spools from which the yarn is wound are
of different diameters and consists in arrangements whereby we are enabled to
maintain an uniform tension in each of the yarns or threads as they are wound
upon the bobbin aforesaid.
For this purpose we provide a shaft or roller extending from end to end of the
winding frame to which shaft rotatory motion is imparted from any convenient
part of the winding frame or machine.
To a rail extending lengthwise of the frame or machine aforesaid, are affixed
brackets to which is jointed a frame provided with two rollers capable of revolving
freely therein, the lower one of which rests upon and receives motion from the
above named shaft or roller.
The previously named frame is provided with slots for supporting the upper of
the previously mentioned rollers. The yarns or threads in their passage from the
spools or bobbins to the tube or bobbin upon which they are to be wound are
passed between the above named rollers which, as they revolve, deliver the yarns
or threads with an uniform tension to the bobbin upon which they are to be
wound such bobbin being driven by any convenient or usual surface motion.
We cause the stop motion which arrests the motion of the bobbin or spool upon
which the yarns or threads are to be wound, to also arrest the motion of the two

page_text: rollers above named, so that they may also cease to deliver the yarns or threads.
For this purpose we connect by means of rods and levers the stop motion above
referred to and the frame carrying the two rollers previously mentioned, so that
when the said stop motion is brought into action by the breakage of one of the
yarns or threads, the before mentioned frame is turned so as to raise the lower of
the previously mentioned rollers clear of the shaft or roller, from which it receives
rotatory motion, and to accelerate such stoppage we cause the said lower roller to
come in contact with a friction break. The lever connecting the above named
frame with the stop motion we form with a slot so that the bobbin upon which
the yarns or threads are wound may be raised clear of the surface drum by which
it is driven, in order that the yarns or threads may be more readily pieced.
