Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I THOMAS THORPE of Beech Avenue New Basford in the Town and County of
the Town of Nottingham, Manufacturer and Machine Builder do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN STOP-MECHANISM FOR
UPRIGHT-SPINDLE WINDING-MACHINERY "to be as follows that is to say :-
This Invention relates to machines employed for winding two or more threads
together on tubes spools or bobbins and it has for its object the improved
construction and arrangement of mechanism for such machines whereby the
rotation of any spindle is automatically and quickly stopped on the breakage
of any thread that is being wound thereon.
In carrying out the Invention the spindles carrying the tubes spools or bobbins
have fixed upon each of them a small bevil friction wheel which is driven by
a small bevil wheel having its axis at right angles to it. This bevil wheel is driven
by a band or cord from a drum or first motion shaft which is arranged to give
motion through the whole series of bevil wheels to the spindles of the machine.
The driving bevil wheels are each carried on one end of a lover piece which is
centered near its middle so that the arm from the centre to the bevil wheel is
horizontal or nearly so when the spindle is being driven. The other and inner end
of the lever curves upwards and terminates in a hook or catch which engages with
a catch at the lower end of a vertical rod centered at its upper end to a part of the
framing about the middle of the machine. This vertical rod carries near its middle
a flat guide plate having in it holes slots or notches to receive the lower ends of
vertical wires. These vertical wires are hinged to the horizontally placed ends
of detector wires centered near their middles which detector wires have their other
ends curved upwards towards the back of the machine and the threads being
wound are passed under two horizontal bars and over the bent en ls of the detector
wires. The curved ends of the detector wires reach to the space between the two
horizontal bars and are weighted to rise between them but are prevented from so
rising by the tension of the thread passed over it. When however a thread breaks
or fails and the end of the detector lever rises it depresses its other end and also the
vertically hanging wires so that an enlargement or a bend in these vertical wires
comes into contact with a rocking shaft which runs the whole length of the
Prim 71

page_text: machine and is carried at the upper end of levers centered below the horizontal
ends of the detector wires. This rocking shaft is worked by a link or rod connected
to a toothed wheel gearing with a wheel on the driving drum. The instant the
vertical wire is lowered by the breaking of a thread and the enlargement on the
wire comes into contact with the rocking shaft the vertical catch lever carrying
the plate guiding that vertical wire is knocked away and releases the lever piece
carrying the driving bevil wheel. The bevil wheel at once rises out of contact
with the bevil whoel on the spindle whilst at the same time a short curved rod or
piece fixed or formed underneath the horizontal end of the lever piece rising with
it comes into contact with the underside of the bevil wheel on the spindle and acts
as a break thus quickly stopping the rotation of the spindle and preventing the
broken end from being wound on the spool. The rapidity with which the rotation
of the spindle is stopped is so great that sufficient length of thread is left unwound
that no difficulty is experienced in tying together the broken ends and the necessity
which has hitherto existed of tying all the threads in one knot when one breaks or
fails is obviated.

page_text: I, THOMAS THORPE of Beech Avenue New Basford, in the Town and County of
the Town of Nottingham, Manufacturer and machine builder, do hereby declare
the nature of my said Invention for "IMPROVEMENTS IN STOP. MECHANISM FOR
UPRIGHT SPINDLE WINDING MACHINERY," and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement that is to say :-
:
My said Invention relates to machines employed for winding two or more
threads together on tubes, spools or bobbins and it has for its object the improved
construction and arrangement of mechanism for such machines whereby the
rotation of any spindle is automatically and quickly stopped on the breakage or:
failure of any thread that is being wound thereon.
In carrying out my said Invention the spindles carrying the tubes, spools on
bobbins have fixed upon each of them a small bevil wheel having its axis at right
angles to it. This bevil wheel is driven by a band or cord from a drum or first
motion shaft which is arranged to give motion through the whole series of bevil
wheels to the spindles of the machine. The driving bevil wheels are each. carried
on the ends of levers which are centered so that the arms from the centres to the
bevil wheels are horizontal or nearly so. The other and inner ends of these levers,
terminate in a hook or catch part which engages with a catch part at the lower
ends of vertical rods centered on the framing and these vertical rods have upon
them guide parts for vertical wires or detectors. These detectors have upon them
or are connected to parts which on the falling of the detector through the breaking
of the thread come into contact with parts on a vibrating arm on a rocking shaft
and are thus pressed against the vertical lever. By this action the vertical lever is
caused to release the bevil wheel lever, which lever being counter weighted takes
the driving bevil wheel away from the spindle bevil wheel, whilst at the same time
an arm or part on the driving bevil wheel lever is pressed against the underside of
the spindle bevil wheel, thus effectually and quickly stopping the rotation of the
spindle.
And in order that my said Invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings to
be hereinafter referred to and representing my improved apparatus. In these
drawings the same reference numerals are used to mark the same or like parts;
wherever they are repeated.
Figure 1 on the accompanying sheet of drawings is a transverse vertical section.
of part of an upright spindle winding machine having my improved arrangement
of stop mechanism. Figure 2 is a front view of one spindle and parts connected,
therewith. Figures 3 and 4 are full size views of details and will be hereinafter
referred to. The upright spindles 1 for carrying the tubes, spools or bobbins, on
which threads have to be wound are carried in a row along the frame in the usual
manner and the spindles 1 may be of the ordinary kind except that they have
fixed upon them each a small frictional bevil wheel 2 at a little distance from their
footstep bearings 3. As it will be more convenient to describe the parts of
apparatus connected to one spindle and their action, than to describe a series, the
following description relates to one spindle only, it being understood that every
spindle in the machine is arranged in an identical manner. There is arranged to
gear with the bevil wheel 2 on a spindle 1 a similar frictional bevil wheel 4 which

page_text: is fixed on one end of a short axis or journal 5. This axis 5 is carried by its
middle in bearings transversely near the outer end of a nearly horizontal lever 6
which is centered near its middle on a journal 7 carried by a bracket on the framing
of the machine. On the other end of this axis 5 there is fixed a grooved pulley 8
which has passed round it an endless driving cord which is also passed round a
driving drum or cylinder 9. This drum 9, is carried in bearings at each end of the
machine near the back,, and has motion imparted to it in the usual way. The
lever 6 has a handle formed on its front or outer end beyond the bearings of the
axis 5, and at its inner end it has screwed into a rebated part a small steel nose
piece 10 which is bevilled on its top side so as to form an inclined guide piece.
The under side of this piece 10 is arranged to rest upon a small ledge formed at
the bottom end of a vertically placed lever 11. This lever 11 has formed on its
side nearest the spindle 1 and about at its middle a hook 12, by which it is hung
upon and centered on a rod 13 extending along the machine near its centre the
rod 13 being placed above the line of the lever 6, and the lower end of the lever 11
projects slightly backwards. At the lower end and on the inner side of this
lever 11 there is screwed a curved piece 14 of hard metal which curves round
under the end of the lever and projects slightly beyond the line of the lever 11
and forms the ledge on which the piece 10 catches, when in a certain position.
The curved piece 14 extends downwards and curves backwards towards the back
of the machine terminating in a point. At the upper end of the lever 11 thero is
screwed a small metal piece 15 having in the face placed against the lever 11 a
vertical groove or recess and in this groove there is fitted a small wire detector
piece 16. When there are several threads to be wound on each spindle each
lever 11, along the frame carries similarly arranged detector pieces 16, one for each
thread. This detector piece is shown full size in Figure 3 and it is formed with
two curls 17, 18 at its top part, and at its lower end there is fixed a small square
piece 19 of metal. The thread to be wound is passed through the upper curl 18
of the detector 16 whilst one end of a long wire 20 is inserted in the lower curl 17.
This wire 20 rests near its middle upon an adjustable bar 21 and forms a counter-
weight the bar 21 being moved to or fro under the wire 20 to suit the weight of
thread being wound. On a thread breaking or failing, the detector connected
therewith will fall and bring its squared end 19 into contact with a projecting
piece 22 fixed on a bar 23 the squared end 19 preventing the detector turning
round. This bar 23 is carried by arms 24 fixed on a rocking shaft 25 carried in
bearings on the framing a little behind the lower end of the lever 11. A slight
vibratory to and fro motion is given to the bar 23 and piece 22 by means of
links 26 connected to the upper ends of the arms 24 and to an eccentric 27 driven
by gearing from a first motion shaft. When a detector falls the vibrating piece 22
through the squared end 19 pushes the upper end of the lever 11 forward releasing
the nose piece 10. The inner end of the lever 6 having a counterweight 28
attached to it falls and lifts the bevil wheel 3 away out of contact with the bevil
wheel 2 thus ceasing to drive the spindle 1. In order to quickly stop the continued
rotation of the spindle a downwardly curved arm 29 is fixed on the lever 6 near
the axis 5 and this arm 29 carries at its lower end a horizontal flat plate 30
covered with leather or other frictional material, When the lever 6 is released
from its catch this plate 30 is raised and pressed against the underside of the bevil
wheel 2 and quickly destroys its acquired momentum. The rapidity with which
the spindle is stopped is great enough to allow of sufficient length of thread being
left unwound so that no difficulty is experienced in tying together the broken
ends, and the necessity which has hitherto existed of tying several threads in one
knot, when winding more than one thread, when one of them breaks or fails is
obviated. When the broken thread is again passed through the curl 18 the
winding action is recommenced by the attendant depressing the handle on the
lever 6. This action brings the two bevil wheels 2, 3, into gear, and they are kept

berein before described again takes place.
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
°
1. The combination and arrangement of parts of apparatus forming improved
stop mechanism for the upright spindles of winding machinery substantially as
herein before described with reference to the accompanying drawings.
2. The combination of detectors (16) counterweight wire (20) adjustable
bar (21) vertical catch lever, (11) and horizontal counterweighted lever (6) sub-
stantially as and for the purposes hereinbefore described with reference to the
accompanying drawings.
