Improvements in Stop-motions of Machines for Beaming Yarn.
I ALFRED HITCHON of Globe Works, Accrington in the County of Lancaster,
Machine Salesman, do hereby declare the nature of this invention to be as
follows:
This invention relates to machines for purpose aforesaid, and is dosigned to effect.
the requisite motion of the acting nip roller, by means of lighter or thianer drop pins
than hitherto available, whereby the yarn or ends carrying lighter faller pins are less
liable to breakage.
According to this my said invention I mount or hang the moving nip roller from
its two ends upon two independent hanging suspenders, preferably connected with the
pin rail, so that when an end breaks, a pin drops, and the moveable nip roller
operates by swinging outwards on its suspender its opposite end acting as a fulcrum,
the necessary movement to act on the knocking off lever being obtained by the
movement practically of one end of the moving nip roller instead of as heretofore
imparting when rollers suspenders have been used a parallel motion to the nip roller
and its suspenders throughout their entire length.
The pin rail may be provided at its ends with axles on which it is free to oscillate
and the suspender levers aforesaid may be mounted thereon thereby rendering the
employment of a cross shaft for carrying the swinging levers unnecessary, one of the
latter levers being made fast to the axis of the pin rail to convey the motion to
the knocking off finger and to the stop lever at the opposite side of the machine.
The opposite hanging or moving nip rollers suspender is mounted loosely on its
axis at the end of the pin rail and is prolonged so as to operate independently on the
knocking off lever whereby it will be seen that the motion given to either end of
the swinging nip roller is sufficient to effect the knocking off and stop the machine.
In cases where it may be desirable the pin rail should not oscillato I mount both
the aforesaid swing levers loosely on independent studs and employ an oscillating
cross shaft to convey the motion that is seperately given to each swinging hanger for
knocking off the machine.

Improvements in Stop-motions of Machines for Beaming Yarn...
I ALFRED HITCHON of Globe Works, Accrington in the County of Lancaster,
Machine Salesman, 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 relates to machines for purpose aforesaid, and is designed to effect
the requisite motion of the acting nip roller, and by means of which I am enabled to
use lighter, and thinner drop pins than heretofore available, whereby the yarn, or
"ends" carrying lighter faller pins, are consequently less liable to breakage, and my
invention consists in mounting the moving nip roller upon two hanging suspenders,
or levers, so that when an "end" breaks, à faller pin drops, and the movable nip
roller operates by swinging outwards, on its suspenders, or levers, and the necessary
motion is given for acting on the "knocking off" lever, and stopping the machine,
being obtained practically by the movement of one end of the moving nip roller, the
other, and opposite end acting as a fulcrum.

page_text: Such being the nature, and object of my said invention the following is a complete
description of same, reference being made to the accompanying drawings in
which
Fig. 1. is an end elevation of an ordinary beaming frame, with my improvements
applied thereto.
Fig. 2. is a front elevation of the same with the centre portion of the oscillating
pin rail broken away, to clearly illustrate pin nicks in same..
According to this my said invention I nount, or hang the moving nip roller 9 from
its two ends 10. 10, upon two independent hanging suspenders, or levers 6. 8, pre-
ferably connected with the pin rail 5, so that when an end breaks, a pin drops through
one of the pin nicks 11, and falling between the two rollers 9-9 the movable nip roller 9
operates, by swinging outwards, or away from the roller 9 on its suspender 6, the
opposite end of the said roller 9 acting as a fulcrum, the necessary movement to act
on the "knocking off" lever 7 being thus obtained by the movement practically of
one end 12 of the moving nip roller 9, instead of, as heretofore, imparting (when
roller suspenders have been used) a parallel motion to the nip roller 9, and its
suspenders, throughout their entire length.
The pin rail 5 may be provided at its ends with axles 13. 13. on which it is free to
oscillate, and the suspender levers 6. 8 aforesaid may be mounted thereon, thereby
rendering the employment of a cross shaft, for carrying the levers 6. 8. unnecessary,
one of the latter levers 8 being made fast to the axis 13 of the pin rail 5 to convey the
"motion to the "knocking off" finger 7 and the stop lever 14 at the side of the
machine.
The opposite hanging, or moving nip roller suspender 6 is mounted loosely on its
axis at the end of the pin rail 5, and is prolonged at 18 so as to operate independently
on the "knocking off" lever 14, whereby it will be seen that the motion given to
either end of the swinging nip roller 9 is sufficient to effect, the "knocking off," and
stop the machine.
In cases where it may be desirable the rail 5 should not oscillate, I mount both the
aforesaid swing levers 6. 8 loosely on independent studs, and employ an oscillating
cross shaft to convey the motion that is seperately given to each swinging hanger, or
lever 6. 8 for "knocking off" the machine.
At 6 is the swing nip roller bearing, and "knocking off" lever 14 combined, and
loosely mounted on the axle 13 of the pin rail 5, at 8 is a like lever, but this is fixed
to the pin rail 5 in order to assist in transmitting the oscillating action to the
"knocking off" finger 7 which is secured on the opposite end of the pin rail 5.9ª is
the driving nip roller which takes the "drop pins" forward to give the oscillating
motion to the pin rail 5. The upper positions 17. 17. of the levers 6. 8 form
convenient handles, or attachinents for same.
Having now particularly described, and ascertained the nature, and object of my
said invention, and in what manner the same is to be employed I declare that
what I claim is :-
1. In machines for beaming yarn the mounting of the swing nip roller 9 in inde-
pendent swing bearings, or suspender levers, the latter being connected with the
stopping mechanism, as, and for the purpose herein described, and substantially as
illustrated by the accompanying drawings.
2. The combination of oscillating pin rail 5, and the "knocking off" levers, for
operating on the stopping mechanism of yarn beaming machines, and actuated by
drop pins" falling from the broken threads, or "ends" of yarn, as herein described
and as illustrated by the accompanying drawings.
