I, ROBERT BROADBENT of the Phoenix Iron Works, Stalybridge in the County
of Lancaster, machinist 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:—
My invention relates to the carriers, swings or frames, herein after called carriers
used for carrying the pegs, spindles or skewers supporting the bobbins, spools or
tubes in machines for winding yarns or threads in which the bobbins, spools or
tubes are rotated by contact with revolving drums or pulleys, and my improve-
ments are more particularly applicable to machines in which the yarn or thread
is wound upon paper or wood tubes or spools without flanges. In such machines
the carriers cannot be made heavy or weighted as the weight would cause the
yarn or thread to run off the ends of the bobbin formed by the yarn. In con-
sequence of this any irregularities in the thickness of the paper or other tubes
or of the yarn cause the carriers to shake or vibrate up and down and the winding
on to become irregular. The object of my improvements is to prevent this shaking
or vibration in a more complete and satisfactory manner than has hitherto been
done.
In order that my invention may be more readily ascertained and carried out,
I have hereunto appended a sheet of drawings marked with letters of reference,
Figure 1 shows a pair of carriers with my improvements in plan and figure 2 in
section; figures 3 and 4 show a modification of the same.
The carriers a and b are centered or hinged upon a rod c and tapped for the
screws d and e respectively. Between the screws and the rod c bent spring
blades ƒ and g are inserted and bent to fit the rod c at the ends touching the rod.
The ends of the screws are preferably reduced in diameter and the spring blades
perforated as shewn to secure the position of the springs in the carriers. By
means of the screws the springs may be more or less compressed and thus more
or less pressure and friction produced between the springs and the rod c and
between the rod and the lugs of the carriers, which prevents the shaking or
vibration of the carriers and produces a regular winding on of the yarn.

page_text: Instead of the springs being made in the forms shewn on figures 1, 2, and 3, 4,
they may be arranged as shewn on Figure 5. Each spring blade g¹ or f¹ is
perforated for the screws e¹ or d¹ to pass through it and clips the shaft c¹ on the
side farthest from the screw, so as to be expanded by the screw and thus to
produce the pressure and friction. It is obvious that in this case the springs and
screws must not be placed opposite each other but so that the springs can pass
each other.
Hitherto helical springs have been used for the purpose of stopping the vibration
of the carriers, inserted between the lugs a¹ and b¹ (figures 1 and 3) and surrounding
the rod c. With this arrangement the pressure and friction is produced between
these lugs and those outside of them. It cannot be adjusted and if made sufficient
to prevent vibration causes too much friction between the lugs, so that, when a
carrier on one side of the rod is raised, that on the opposite side is depressed and
the bobbin spoilt. If made light enough to obviate this drawback, the friction is
insufficient to prevent vibration. My improved arrangements of springs prevent
these inconveniences and permit an exact adjustment of the pressure and friction
for each carrier independently of the other and their independent movement.
It is obvious that instead of the carriers for both sides of the machine being on
one rod, they may be centered or hinged on separate rods or supported on pivots
in brackets fixed to the machine and the springs arranged in a similar manner
to that hereinbefore described between the carriers and the rods, pivots or bosses
of the brackets.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I hereby declare that
what I claim is
The arrangement of bent spring blades and adjusting screws in the bobbin
carriers of drum winding machines substantially as herein before described and
illustrated by the drawings and for the purposes set forth.
