Improvements in or relating to Bobbin Holders for Spooling
Machines.
I, NICHOLAS HOWARD EASTON, of 164 Cross Street, Central Falls, in the
Gounty of Providence, and State of Rhode Island, United States of America,
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 :-
This invention relates to a holder or support for a bobbin while the yarn is being
removed therefrom, and rewound upon a spool in a spooling machine; and it
consists in the employment of a counter-balanced pivoted cradle or holder for the
bobbin, and a pivotally held gravitating tension arm, the said cradle and gravitating
tension arm, being arranged to rock from side to side, to relieve the yarn from
undue strain, while it is being wound from the bobbin onto the spool: the
gravitating arm serving to steady the bobbin at its drawing side, and produce the
required uniform tension upon the yarn.
In the accompanying drawings:
Fig. 1, represents a side view of a bobbin-holder or support, embodying the
invention, with the bobbin in place therein.
Fig. 2, represents a direct front end view, taken in line with the axis of the
bobbin.
Fig. 3, represents a section, taken in the line 3, 3, of Fig. 1.
The bobbin-holders or supports are intended to be located side by side, and to
be mounted upon the spooling machine in any suitable manner, as by being
attached to a rod or bar A, which runs longitudinally of the machine, each holder
being placed in front of a spool, upon which the yarn of the bobbin is to be wound
by the usual mechanism; B is the inclined cradle, in the trough a, of which, the
bobbin C is loosely placed, to rest with its inner end against the head d, the said
cradle being loosely pivoted to the frame D, by means of the center pointed
screws e, e, shown by dotted lines in Fig. 1, and provided with the counter-
balancing weight f.
The frame D is secured to the rod or bar A, by means of the set screw 9, and is
provided with the slots h, h', in which are pivotally held the opposite ends i, i¹, of
the swinging gravitating arm E, so that while the said arm has a swinging
movement, with the swinging movement of the cradle B, and the bobbin C, it may
also have an up and down movement; such up and down movement being caused
by the tension of the yarn b, as it is being drawn from the bobbin against the side
of the bar c, of the gravitating arm E, the pivot ends i,, of the gravitating arm,
rising and falling as occasion requires in the slots h and h', in the frame.
The tension of the yarn 6 forces the bar c of the gravitating arm E against the
side of the yarn F on the bobbin and tends to secure a uniform tension between
the bobbin and the winding spool; an excess of tension being relieved by the
resulting upward movement of the gravitating arm E.
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 :-
The combination with the frame, and the counterbalanced pivoted cradle for
holding the bobbin. of the gravitating tension arm. adapted to swing with the

page_text: cradle and to have an up and down movement caused by the tension of the yarn
from the bobbin, substantially as described.
Dated the 31st day of July 1894.
