We PRINCE SMITH the Younger of the firm of Prince Smith & Son of Burlington
Shed, Keighley, in the County of York, Machine Maker, and SMITH AMBLER of the
same place, Draftsman in the employment of the said firm do hereby declare the
nature of this invention to be as follows:-
-
Our invention relates to improvements in apparatus for trapping broken or other
loose ends in twisting or such like frames.
The delivery roller according to the present invention is mounted on an upright
spindle much as usual but the spindle itself we mount in a swing frame which swing
frame swings in a bracket or sustaining part bolted or secured onto a horizontal bar
of the frame. On the spindle of the delivery roller is a worm wheel the teeth of which
gear with a worm on a horizontal shaft and therefrom receive rotatory motion when
the twisting is progressing correctly, but when thread breaks or fails these parts are
disengaged as will be herein more fully explained.
The lower end of the spindle supporting swing lever can traverse front to rear in a
guide way formed in a part bolted to a horizontal support.
On the boss of the wheel on the delivery roller spindle are two projections say pins
in opposite directions.
On the beam across the frame is applied a bracket which supports a balance lever
the hand part of which lever has a rearwardly extending part hinged to the said
balance lever so as to be capable of swinging laterally in one direction, or of being
thrust sidewise.
On the horizontal bar carrying the swing frame bracket is secured an arm or
centre of motion for a sneck lever or swing weighted trigger lever which is arranged
that it can be so adjusted as to normally support the swing frame in its working

page_text: position but when the trap lever through which pass the threads or ends to be twisted
rises, owing to the breakage or failure of an end, then this hinged end drops, comes in
the path of the rotating projections of the delivery roller wheel boss and is struck on
one side thereby and being so struck it strikes against the trigger or sneck and knocks
that support from under the swing frame and the swing frame falling forward above
its hanging centre, its lower portion swings rearward disengaging the gear wheel from
the driving wheel and throwing the apparatus out of operation.

page_text: We PRINCE SMITH the Younger of the Firm of Prince Smith & Son of Burlington
Shed Keighley in the County of York Machine Maker and SMITH AMBLER of the
same place Draftsman in the employment of the said firm 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 invention relates to improvements in stop motion apparatus for trapping broken
or other loose ends in twisting or such like frames as soon as an end breaks and so
preventing waste.
DESCRIPTION OF THE DRAWINGS.
The delivery roller a from which the end is delivered from the bobbin on the creel
not shown according to the present invention is mounted on an upright spindle b much
as usual but the spindle 6 itself we mount in a swing frame c which swing frame c
swings on centres or trunnions c¹ carried in recesses d' in a bracket or sustaining
part a bolted or secured on to a horizontal bar e of the frame. On the spindle b of the
delivery roller a is a worm wheel of the teeth of which gear with a worm g¹ on a
horizontal shaft g and therefrom receive rotatory motion when the twisting is progressing
correctly, but when the thread / breaks or fails these parts are disengaged as will be
herein more fully explained.
The lower end of the swing lever c supporting the spindle b and delivery roller a can
traverse front to rear in the guideway formed in the part k bolted to the horizontal
support when its retaining parts are released.
On the boss of the wheel on the delivery roller spindle bare pegs or projections f
projecting in opposite directions preferably two in number although this number may
be varied.
On the beam h running across the frame is applied a bracket i which supports a
balance lever j the rearwardly projecting part j₁ of which lever has a further rearwardly
extending part,hinged at to the said rear end ; so as to be capable of swinging
laterally in the direction of the arrow Figure 2 or of being thrust sidewise.
On the horizontal bar e carrying the swing frame bracket d is secured an arm or
centre of motion n for a sneck lever or swing weighted trigger lever m which is
arranged that it can be so adjusted vertically as to normally support the swing frame
in its working position but when the trap lever j through the eye of which passes
the thread or end to be twisted rises owing to the breakage or failure of the end then
this hinged end drops, comes in the path of the rotating projections ƒ of the boss f
of the wheelf on the end of the axis 6 of the delivery roller a and this swinging end
is struck on one side thereby and in its course being so struck it strikes against the

page_text: trigger or sneck m and upsetting it on its fixed centre n it knocks the support from
under the trunk arm c³ which had rested on the arm and thereby supported the swing
frame c upright and the swing frame c falling forward above its hanging centre its
lower portion swings rearward disengaging the gear wheel ƒ from the driving wheel g¹
and throwing the apparatus out of operation.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The combination in a stop motion for preventing waste in twisting and other
frames, of a swing frame c carrying the delivery roller by its spindle b, gear pinion f
for gearing with the driving wheel g', supports and guides therefor, trigger lever m,
trap lever, and its hinged parts, all substantially as set forth.
2. The combination in a stop motion for waste prevention in twisting frames and
like apparatus, of a swing frame as c carrying the delivery roller driving gear ƒ capable
of being engaged with or disengaged from its operating gear g¹, a trigger lever m
the placing and displacing of which engages and disengages the gears ƒ and g¹
with a trap lever j and its hinged parts, substantially as shewn for the purpose
specified.
3. The combination in a stop motion for twisting frames and like apparatus of a
balanced trap lever having a hinged end, a trigger support for said trap lever end, and
a gear driving the axis of the delivery roller suspended in a swing frame swinging
about centres between guides and in proximity to a driving gear as g' substantially as
shewn for the purpose specified.
