PROVISIONAL SPECIFICATION.
Improvements in Winding Frames for Yarn and the like.
We, THOMAS GUEST and THOMAS BROOKES, of Poland Street, Oldham Road,
Manchester, in the County of Lancaster, Machine Makers, do hereby declare the
nature of this invention to be as follows:-
Our improvements has reference to the stop motion of winding frames, whereby
when a thread breaks the winding bobbin is caused to stop, and thus preventing
waste.
We use the ordinary pivotted box, containing drop wires for each thread, which
when a thread breaks the wire falls and is operated on by an angular revolving
shaft, or ratchet, and stops the winding bobbin.
We place the ordinary bobbin levers or cradle in front of the winding drum at
an angle upwards to the drum. They are jointed to the top end of an upright
lever or levers suspended on a shaft working in bearings attached to the framing
and when working are hanging perpendicular. They are kept in their position by
the lower end of the lever being made with a notch, which takes hold of a finger
attached to the pivotted box, the box being so weighted that the finger drops
into the notch of the upright lever when the latter is in position for working.
When a thread breaks and the drop wire falls, the wire is immediately acted on
by the revolving angular shaft which swivels the box and takes the finger out of
the notch of the upright lever, the bobbin levers or cradle with the bobbin,―by
their own weight, then instantly falls or moves downwards on the winding drum
and the bobbin is caught by an incline or brake at the front of the winding drum
which stops at once the motion of the bobbin and consequently the winding.
The bobbin in falling or moving downwards on to the brake, causes the upright
lever to swivel, and the lower end of the lever from one side of the notch, being
made to form an incline, eccentric with the centre of the lever, acts on the finger
of the wire or pivotted box moving the box farther round and thus holding the
drop wires completely out of the way of the revolving angular shaft.
To support the bobbin off the brake when piecing a thread, we place a weighted
lever on any convenient centre below the bobbin cradle, which is kept in its
position by a stop, but free to move in one direction, it is made long enough and
formed so that the cradle with the bobbin, when falling towards the brake, pushes
or carrys the lever in the direction it can move, by the action of a projection in the
cradle.
The worker then lifts the cradle with the bobbin off the brake high enough to
allow the top of the weighted lever to swivel under the projection on the cradle,
and thus holds the bobbin free of the brake.
When the thread is pieced the worker pushes the bobbin back on to the
winding drum, thus taking the cradle off the supporting lever and causing the
upright lever to swivel so as to bring the notch opposite the finger of the wire box
which immediately drops into the notch by its own weight.

Improvements in Winding Frames for Yarn and the like.
We, THOMAS GUEST and THOMAS BROOKES, of Poland Street, Oldham Road,
Manchester, in the County of Lancaster, Machine Makers, 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 :-
Our improvements has reference to the stop motion of winding frames whereby
when a thread breaks the winding bobbin is caused to stop and thus preventing
waste:
We use the ordinary pivotted box containing drop wires for each thread,
which when a thread breaks the wire falls, and is operated on by an angular
revolving shaft or ratchet and stops the winding bobbin.
In the accompanying sheet of drawings a represents the thread to be wound on
to the bobbin b, and c the winding drum, we place the ordinary bobbin levers or
cradle d in front of the winding drum e at an angle upwards to the drum, they
are jointed to the top end of an upright lever or levers e, suspended on a shaft /
working in bearings of a bracket attached to the framing hand when working
are hanging perpendicular, as shewn in the drawing, they are kept in their position
by a notch at the lower end of the lever, which takes hold of a projection at
the end of a finger attached to the pivotted or wire box k. The box swivels
or works in bearings in the bracket attached to the framing and is so weighted
that the projection at the end of the finger j drops into the notch at the bottom.
of the upright lever, thus keeping it in the position for working, when a thread
breaks and the drop wire m falls, the wire is immediately acted on by the ordinary
revolving shaft or ratchet n which swivels the box and takes the projection at
the end of the finger j out of the notch of the upright lever, the bobbin levers
or cradled with the bobbin & then instantly falls or moves downwards on the
winding drum by their own weight, and the bobbin is caught by an incline or
brake o fixed to a bracket attached to the framing at the front of the winding
drum which stops at once the motion of the bobbin and consequently the winding.
The bobbin in falling or moving downwards on to the brake causes the upright
lever to swivel, and the lower end of the lever from one side of the notch, at p,
being made like a tappet or eccentric from the centre of the lever acts in the.
projection at the end of the finger of the pivotted box, thus moving the box
farther round and holding the drop wires completely out of the way of the revolving
angular shaft or ratchet.
To support the bobbin off the brake when piccing a thread, we place a weighted
léver q on the shaft, or on any convenient centre below the bobbin cradle, and
which is kept in its position by the lower end of the lever resting against the
framing but free to move in the opposite direction, it is made long enough at
its top part to support the cradle at its proper height, and the cradle with the
bobbin when falling towards the brake pushes or carrys the lever with it by
the action of a projection on the cradle, the worker then lifts the cradle with
the bobbin off the brake high enough to allow the top end of the lever to swivel
by its own weight under the projection on the cradle, thus holding the bobbin
free of the brake and allowing the worker to get the thread pieced.
When the thread is pieced the worker pushes the cradle and bobbin back on
to the winding drum, thus taking the cradle off the supporting lever q and at the
same time causing the upright lever e to swivel so as to bring the notch at its lower
end opposite the projection on the finger of the pivotted or wire box which
immediately drops into the notch, and the winding proceeds.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we hereby declare
that what we claim is :-
First
The lever - with its tannet or eccentric form at its lower end for mushing
P

page_text: and keeping away the drop wire from the revolving angular shaft or ratchet, as
-shewn and described.
Second The weighted upright lever g, for supporting the cradle when piecing a
thread, as shewn and described.
