COMPLETE SPECIFICATION filed by the said Herbert John Haddan at the
Office of the Commissioners of Patents on the 8th November 1877.

"IMPROVEMENTS IN
BOBBIN HOLDERS AND BOBBINS." A communication from abroad by Martin Joseph
Nealon and Timothy Higgins, Builders, both of the City of Chester, and State of
Pennsylvania, United States of America.
The Invention relates to an improvement in bobbin holders and bobbins, and it
consists in so constructing the holder and bobbin, that the rotary power for turning
the bobbin around is applied to the outside of the bobbin, whereby the bobbin is
prevented from being split and broken, as will be more fully described hereafter.
The accompanying Drawings represent the Invention, a represents the bobbin
holder, and c the bobbin.
The holder is constructed in the usual manner, with the exception of the top,
where it has a cornered recess d, of any suitable shape, made in its top, and which
is made of any depth required.
The bobbin is also made in the usual way, with the exception of its lower end,
where it is shaped so as to fit in the recess d in the top of the holder. By means
of this construction the rotary power for revolving the bobbin is applied to its
outside entirely, thereby effectually preventing the bobbin from being split and
cracked, as is so frequently the case where the power is applied at any other point.
Not only can the holders be made more cheaply by constructing them as above
described, but all the old bobbins that have been thrown away as cracked and
useless can be fitted to these holders and again used, as good as new, by simply
squaring their ends so as to fit in the recesses in the tops of the holders
[Price 4d1

rise upward and get loose from their holding device, as is very common with some
of the holders now in use.

I am aware that it is not new to revolve small bobbins, such as are used on
'fliers," by applying the rotary power to the outside of the bobbin. I am also
aware that the lower ends of the bobbins have been stuck in round sockets where
they have been held by frictional contact, and these features I disclaim. Where
the ends are held by frictional contact alone the ends are. constantly being worn
away, and soon become too small to be any longer used; and, besides, such a
method can only be applied to small bobbins.
By holding the ends in a cornered or irregular shaped recess I am enabled to use
larger bobbins; can also by shaping the ends to fit my sockets use up all the old
cast-away bobbins, and thus effect an immense saving and prevent any wear
whatever upon the bobbin while being used.
Having thus described the Invention, I claim a bobbin holder, having a cornered
or eccentrically shaped recess made in its top to receive the lower end of the bobbin
and rotate the same, and whereby also the ends of old cast-away bobbins can be
reshaped to fit this recess and again be used, substantially as shown and described.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
hand and seal, this Eighth day of November, in the year of our Lord One
thousand eight hundred and seventy-seven.
