Improvements in Spinning Machines.
We, BRINTONS LIMITED of Kidderminster in the County of Worcester, Wool
Carders and Combers, Worsted Spinners and Carpet Manufacturers and CHARLES
OSBORNE of 34 Park Street, Kidderminster aforesaid, Mechanic, do hereby declare
the nature of this invention to be as follows:-
This invention has reference to spinning machines and has for its object the
prevention of waste and the production of a better material.
The invention mainly consists of a novel mechanism or means for automatically
stopping or checking the feed when the thread or yarn breaks, or when for any
reason pressure is removed from the guide through which the material runs before
passing to the spindle and bobbin.
For the purpose of our invention we suspend a swinging bracket or trap, herein-
after called the trap, from a bar which may conveniently be fixed to the carriages or
stands of the lower back feed roller. This trap has at the upper part jaws which
support the upper back feed or pressing roller, and it has also projections to nip the
material as hereinafter described. The trap has also at its lower part an arm or
lever which projects beyond the "ratch" stand and carries a friction roller. This
roller rests upon a movable bar which is parallel with the ratch stand and is fitted
with a spring which tends to push it forward. The said movable bar is bent at
both ends, the bend at the upper end and that at the lower end being parallel with
each other and horizontal or approximately so. The upper end of the bar may
conveniently be supported by a bar and brackets from the creel plate; the lower
end of the movable bar rests in a bracket fixed to the front rail of the frame under
the front feed or drawing roller. Within this bracket is a trigger or lever block
suspended from a horizontal pin in the bracket. There is a thrust rod, one end of
which bears against the lower end of the movable bar and the other end works on
a horizontal pin in the rear of the trigger block; this pin is normally a little above
the line of the centres of the trigger block pin and the lower end of the movable
rod. The guide through which the material runs before passing to the spindle and
bobbin is balanced upon a pin in the last named bracket; at its rear is a small link
upon which hangs a detector pin the top of which slides in a slot in the trigger
block, whilst its lower part slides in a vertical hole in the lower part of the said
block. Immediately below this hole is a rocking shaft carrying a cam or tappet.
The carrier rollers between the back and front feed rollers are made short so as to
act independently upon separate threads instead of upon two or more threads as is
usual.
The operation is as follows:-Supposing the machine to be at work the front of
the guide receives the same pressure or drag as usual and this maintains it in a
horizontal position. If however the thread breaks or the pressure is for any
reason removed, the weight of the link and detector pin draws down the rear end
of the guide and the detector pin thus sinks below the base of the trigger block.
This pin is consequently struck by the tappet on the rocking shaft and the base of
the trigger block is thus pushed forward. As the block moves on its supporting
pin, the pin at the rear on which the thrust rod works is brought below the line of
the centres of the trigger block pin and the lower end of the movable bar. This
bar is therefore free to be pushed forward by its spring, the trigger block being at
the same time forced further round on its centre until the thrust rod pin is brought
directly under the trigger block pin. The fallen detector pin is thus moved clear

page_text: of the rocking tappet and remains so until the parts are returned to their normal
position. The forward movement of the movable bar is horizontal and in this
movement it presses against the arm of the trap and forces the trap upwards. The
projections (preferably two) at the upper part of the trap come in contact with
the upper back feed or pressing roller and nip the material firmly against it, and at the
same time lift this roller clear of the lower back feed roller. The material being
thus moved clear of the feed roller all damage from friction and fraying is avoided
while the material is so firmly gripped that the feed of the same and the delivery
at the front rollers are discontinued. When it is required to return the parts to
their normal or working position the trigger block is moved back by a lever arm
or otherwise, and in this movement the movable bar is pushed back by the thrust
rod; the trap drops, the pressing roller comes again in contact with the back feed
roller and the nip on the material is released; the feed of the material is thus
resumed, the thread being pieced up at the front rollers in the ordinary way.

We, BRINTONS LIMITED of Kidderminster in the County of Worcester, Wool
Carders and Combers, Worsted Spinners and Carpet Manufacturers and CHARLES
OSBORNE of 34 Park Street, Kidderminster, aforesaid Mechanic, 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:-
This invention has reference to spinning machines and has for object the
prevention of waste and the production of a better material.
The invention consists of novel mechanism or means for automatically stopping
or checking the feed when the thread or yarn breaks or when for any reason
pressure is removed from the guide through which the material runs before passing
to the spindle and bobbin.
The accompanying drawing represents a side elevation of so much of a spinning
machine as is necessary to enable our invention to be fully understood. A represents
the "ratch" stand of an ordinary spiuning frame. B is the front or drawing
roller and C the back or feed roller.
"
For the purpose of our invention we suspend a swinging bracket or trap D,
hereinafter called the trap, by lugs D₁ from a bar E which may conveniently be
and is shown as fixed to the carriages or stands of the lower back feed roller in
the position of the ordinary back roller bar of a spinning frame. This trap D has
at the upper part jaws D which support the upper back feed or pressing roller F,
and it has also projections D³ D³ to nip the material as hereinafter described. The
trap D has also at its lower part an arm or lever D which projects beyond the
"ratch stand A and carries a friction roller D2. This roller rests upon a
movable bar G which is parallel with the ratch stand A and is fitted with a
spring g which tends to push it forward. The said movable bar G is bent at both
ends as seen at G₁ G' the bend G at the upper end and that G' at the lower end
being parallel with each other and horizontal or approximately so. The upper end
of the bar may conveniently be and is shown as supported by a bar H and
brackets H from the creel plate H2; the lower end of the movable bar G
rests in a bracket I fixed to the front rail J of the frame under the front feed or
drawing roller B. Within this bracket I one side of which is shown as broken
away to allow the interior to be seen is a trigger or lever-block K suspended from

page_text: a horizontal pin K' in the bracket. There is a thrust rod L one end of which bears
against the lower end G2 of the movable bar G and the other end works on a
horizontal pin in the rear of the trigger block; this pin is normally a little above
the line of the centres of the trigger block pin K¹ and the lower end G² of the
movable rod. The guide M through which the material runs before passing to the
spindle and bobbin P is balanced upon a pin m in the bracket I; at its rear is
a small link m upon which hangs a detector pin N the top of which slides in a
slot n in the trigger block K whilst its lower part slides as seen in the figure in a
vertical hole in the lower part of the said block. Immediately below this hole is
a rocking shaft Q carrying a cam or tappet O. The carrier rollers S S between
the back and front feed rollers are made short so as to act independently upon
separate threads instead of upon two or more threads as is usual. The balancing
of the guide M may be effected in any convenient manner for example by means
of a nut which can be moved in one direction or the other as may be
required.
The operation is as follows:-Supposing the machine to be at work the front
of the guide M receives the same pressure or drag as usual and this maintains it in
a horizontal position as seen in the figure. If however the threads break or the
pressure is for any reason removed the weight of the link m and detector pin N
draws down the rear end of the guide M and the detector pin N thus sinks below
the base of the trigger block K. This pin is consequently struck by the tappet O
on the rocking shaft Q and the base of the trigger block K is thus pushed forward.
As the block moves on its supporting pin K¹ the pin at the rear on which the thrust
rod L works is brought below the line of the centres of the trigger block pin K'
and the lower end G2 of the movable bar G. This bar is therefore free to be
pushed forward by its spring g the trigger block K being at the same time forced
further round on its centre until the thrust rod pin is brought directly under
the trigger block pin K. The fallen detector pin N is thus moved clear of the
rocking tappet and remains so until the parts are returned to their normal
position. The forward movement of the movable bar G is horizontal and in this
movement it presses against the arm D of the trap D and forces the trap upwards.
The projections D³ D³ (preferably two) at the upper part of the trap come in
contact with the pressing roller F and nip the material firmly against it and at the
same time lift this roller clear of the lower back feed roller C. The material
being thus moved clear of the feed roller all damage from friction and fraying is
avoided while the material is so firmly gripped that the feed of the same and the
delivery at the front rollers are discontinued. When it is required to return the
parts to their normal or working position the trigger block K is moved back by a
lever arm K or otherwise and in this movement the movable bar G is pushed
back by the thrust rod L. The trap D drops, the pressing roller F comes again
in contact with the back feed roller C and the nip on the material is released; the
feed of the material is thus resumed the thread being pieced up at the front rollers
in the ordinary way.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
In a spinning machine, mechanism constructed and operating substantially_as
herein before described for automatically stopping or checking the feed when for
any reason such as the breaking of the thread or yarn pressure is removed from
the guide through which the material runs before passing into the spindle and
bobbin.
