ARTHUR CHARLES HENDERSON, of 6, Southampton Buildings, Holborn, in the
County of Middlesex, Patent Agent. "IMPROVEMENTS IN ARRANGING, WINDING,
AND UNITING YARN ON TWO OR MORE BOBBINS TO FORM A SINGLE CONTINUOUS
THREAD, AND IN HOLDING DEVICES FOR SECURING THE ENDS OF THE YARN IN
DOFFING." A communication from abroad by Israel L. G. Rice, and Walter
Trowbridge Bent, both of Cambridge, in the County of Middlesex, in the State of
Massachusetts, United States of America.
The first part of my Invention relates to the formation of a single continuous
thread, by arranging, winding, and uniting the yarn on two or more bobbins, so
that the yarn on all the bobbins may be drawn off from their tops without
stoppage.
The second part of my Invention relates to providing spinning bobbins with
suitable devices for retaining the end of the yarn in the operation of doffing, and
so do away with the practice of winding several turns of yarn round the bobbins,
and also providing bobbins with strengthening rings of metal, rubber, cowhide, or
other suitable material
In the first case when an empty bobbin is placed on a spindle of a spinning
frame, it has a few turns of yarn wound upon it at the bottom of the bobbin by
hand, this is done by the doffer; the object of doing this is to secure a sufficient
length of yarn to tie on to the end of yarn on another bobbin, then the yarn is
spun and wound on to the bobbin as usual, care being taken that in spinning the
yarn is not wound down at the very bottom of the bobbin so as to cover the yarn
that was wound upon it by hand.
After the bobbin is doffed it is placed upon one of the pins of the stand, another
full bobbin is taken from off the spinning frame and placed on a pin in the stand;
now the end of yarn that is on the top of one bobbin is wound round that bobbin
one or two turns, so as to bring it at the bottom of the bobbin, and it is then tied
to the end of yarn that is at the bottom of the bobbin beside it.
It will readily be seen that by drawing off the yarn from the top of one bobbin

page_text: it will all unwind until it finally reaches the point where it is connected with the
yarn on the bobbin beside it.
A shelf in front of the spindle bears the stand of empty bobbins in the operation
of duffing, full bobbins may be taken from the spinning freme, and put upon the
stand, while the empty ones on the stand may be placed on the spinning frame.
The doffers or the spinners can unite the ends of yarn on the bobbins when the
frame is spinning. The end of the yarn first put on the bobbin is slipped into a cut
in the end of the bobbin to keep it from being lost or snarled up.
It is advantageous to so arrange the bobbins that their centres will all point to a
common centre, and at their common centre a guide is placed, through which the
yarn is drawn.
•
In winding the bobbins they should be wound so that the yarn will lie upon
them in a series of cone-shaped layers, as it does on the cops that are used for
filling that are spun on the mule. This being the best mode of rapidly drawing
the yarn off the top.
In the second case the object is to provide a spinning bobbin at its base with a
metallic ring provided with spring flanges or lips, and under which the yarn may
be drawn in the operation of dofting, so as to hold the yarn on to the bobbin instead
of winding the yarn by hand around the bobbin when doffing takes place.
Another object in view is the strengthening of the bobbin to prevent its splitting.
By using this ring all the yarn may be drawn off the bobbin without there being a
snarl at the end of the yarn that was first wound upon the bobbin, as is frequently
the case in the old manner of doffing bobbins.
