We RICHARD NEWSOME WAILES and JOHN WAILES of Providence Mills Batley in
the County of York Woollen Manufacturers do hereby declare the nature of this
invention to be as follows:-
This invention relates to bobbins or spools on which the weft or warp is spun and
wound, and the object of the invention is to construct a bobbin or spool so as to
prevent the waste by the sluffing or sliding of the weft, off the bobbin or spool
occasioned by falls of the bobbin but mainly through the impact and heaving blow of
the picker upon the shuttles tip necessary where large shuttles and course counts of
weft aro employed.
In the construction of bobbins or spools according to this my said invention I form
the outer surface of the spool, or portion on which the weft is wound of different
diameters, and steps or indent portions of its circumference so as to provide lodgment
or holding surfaces in and by which the layer or layers of weft first wound are held
so as entirely to prevent the weft slipping or sliding off the bobbin or spool.
The indentations may be formed around the entire circumference of the bobbin or
spool by sinking or turning down its diameter at intervals of its length, and leaving a
sharp or angular shoulder at each part so turned, or the indentations may be formed
by cutting out portions of its circumference at intervals of length, and in opposite
sides of the bobbin or spool. Where the diameter is sunk or turned down atintervals
of length as described I employ a tool having angled cutters attached so as to perform
the operation of turning and recessing the several recesses at one or more operations;
where indentations are made in a portion only of the diameter, circular revolving
cutter or cutters and fences or stop pieces are employed.
I am aware that prior to this my invention that the circumference of bobbins or
spools have been recessed or indented by means of semicircular grooves to which I lay
no claim, nor are such grooves efficient or effective for purpose of preventing the slufting
off and waste of yarn which is the main object of this invention to avoid and prevent.

We RICHARD NEWSOME WAILES and JOHN WAILES of Providence Mills Batley in
the County of York Woollen Manufacturers 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 bobbins or spools on which the weft warp is spun and
wound, and the object of the invention is to construct a bobbin or spool so as to prevent
the waste by the sluffing or sliding of the weft off the bobbin or spool occasioned by
falls of the bobbin but mainly through the impact and heaving blow of the picker
upon the shuttles tip necessary where large shuttles and course counts of weft are
employed.
In the construction of bobbins or spools according to this my said invention I form
the outer surface of the spool, or portion on which the weft is wound of different
diameters, and steps or indent portions of its circumference so as to provide lodgment
or holding surfaces in and by which the layer or layers of weft first wound are
held so as entirely to prevent the weft slipping or sliding off the bobbin or spool.
The indentations may be formed around the entire circumference of the bobbin or
spool by sinking or turning down its diameter at intervals of its length and leaving a
sharp or angular shoulder at each part so turned or the indentations may be formed
by cutting out portions of its circuinference at intervals of length, and in opposite
sides of the bobbin or spool-Where the diameter is sunk or turned down at intervals
of length as described I employ a tool having angled cutters attached so as to perform
the operation of turning and cutting the several recesses at one or more operations,
where indentations are made in a portion only of the diameter circular revolving
cutter or cutters and fences or stop pieces are employed.
I am aware that prior to this my invention that the circumference of bobbins or
spools have been recessed or indented by means of semi-circular grooves that is to say
U gouge or spirals, to which I lay no claim nor are such grooves efficient or effective
for purpose of preventing the sluffing off and waste of yarn which is the main object
of this invention to avoid and prevent.
Such being the nature and object of this our said invention the following is a
complete description of same, reference being had to the accompanying drawings:
Figures 1. 2. and, 3 illustrates our invention.
The parts of the bobbin 1. 2. 3. 4 are as shewn of different diameters this variation
is caused by reason of the bobbin being made taper-A portion of the bobbin
at 5. 6. 7 is further reduced in diameter forming steps or indented portions, the

page_text: shoulders 8. 9. 10 being slightly undercut so as to provide lodgement or holding
surfaces in and by which the layer or layers of weft first wound on the bobbin are
held securely and prevented the weft slipping or sliding off the bobbin.
At Figure 2 we have illustrated the cutting out of portions only of the circumference
at intervals of length of the bobbin and such portion and the portions cut away may
be cut at right angles to the centre of the bobbin as shewn at 5ª or they may be
cut at an angle as shewn as 6. 6. 6 the angle permitting the bobbin being turned
and screwed further into the cop when any slackness of the yarn upon the bobbin
is felt.
At Fig. 3 like indentations to 6. 6. 6 of figure 2 are shown also a spiral
indentation cut with the recessed holding shoulder so as to prevent the yarn
slipping off.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. Bobbins or spools having portions and the circumference recessed as shewn
at 5. 6. 7 of Figure 1 for purpose described and as illustrated.
2. Bobbins, or spools having the recessed portions such as 5 or 6-6 for purpose
and as illustrated.
3. Bobbins or spools having the combined recesses and spiral recesses as illustrated
by Figure 3 as herein fully described.
