and king spinning wisting Frames,
We, JOHN DIXON of the firm of John Dixon & Sons of The Bobbin Mills, Stecton
in the County of York, Bobbin Manufacturers, and JAMES LEE of the same place,
Foreman Wood Turner, do hereby declare the nature of this invention to be as
follows:-
This invention relates to certain improvements in the construction of hobbins, and
has for its object the strengthening of the bobbin or spool heads in such a manner, that
protection to the wood is provided so that the driving pins on the tubes employed by
cap or ring spinning and twisting frames do not cut away the wood of the bobbin or
spool heads as is the case when unprotected.
In the head of the bobbin or spool we cut an annular groove concentric with the
centre hole, and also cut away a portion of the wood forming recesses opposite to each
other on each side of the centre hole. Into the groove and recesses we force a melal
hoop hent to the configuration of the same by which the wood is strengthened and
protected, the driving pins on the tubes coming in contact with the metal instead of
the wood as in ordinary spools and bobbins, thereby protecting the same.
JOHN WAUGH,
Agent.

We, Jons DIXON, of the firm of John Dixon and Sons, of The Bobbin Mills, Stecton,
in the County of York, Bobbin Manufacturers, and JAMES LEE, of the same place,
Foreman Wood Turner, 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 certain improvements in the construction of bobbins, and
has for its object the strengthening of the bobbin or spool heads in such a manner, that
the wood of which the bobbin is composed is protected, so that the driving pins on the
tubes employed by cap and ring spinning and twisting frames, do not cut away the
bobbin or spool heads as is the case when unprotected; and consists in cutting an
annular groove in the bobbin or spool head, and forming recesses on each side of the
centre hole into which is pressed a metal hoop with which the driving pins come in
contact, and which prevents the latter cutting the wood as in bobbins and spools of the
ordinary construction.
In describing the invention inore in detail, we will refer to the accompanying
drawings. Figs. 1 and 2 represent the end view or head of a bobbin or spool and
Fig. 3 a side view of a portion of the tool we use for cutting out the slot holes at each
side of the centre hole.
After the bobbin is turned, the annular groove A is cut, to the depth required, in the
end of the hobbin or spool by a ring saw, somewhat similar to those used by blocking
machines, then the slot holes B at each side of the centre hole C of the bobbin or spool
are cut by a revolving cutter larger in diameter at the end E, thereby forming the slot
holes wider at the bottom than at the top.
Into the groove A and recesses B, we press a metal hoop D bent to the configuration
of the same, and in order to reduce the liability of the said hoop coming out of the
bobbin or spool head, we press into each recess an expander having about the same
angle of dovetail, or enlargement at the end, as the before mentioned revolving cutter,
thereby expanding the bottom portion of the metal hoop D to fill the recesses B, thus
securing the hoop in the bobbin or spool head.
By protecting the bobbin or spool head in the manner described, the wood is not
worn away by the driving pins as is the case with those of the ordinary construction,
the driving pins on the tubes coming in contact in the recesses B with metal instead of
wood, do not cut the metal away so readily, thereby the bobbin or spool is preserved
by the introduction of the metal hoop D into the head in the manner described.
Having now particularly described and ascertained the nature of this invention, and
in what manner the same is to be performed, we declare that what we claim is:
The protecting of bobbins or spools used on cap and ring spinning and twisting
frames, by a metal hoop D pressed into an annular groove and recesses B, substantially
in the manner described.
