Improvements in or Applicable to the Bobbins or Spools of the
Shuttles used in Looms for Weaving.
I, WILLIAM HOTHERSALL, of 47, Leeds Road, Nelson, in the County of Lancashire,
Foundry Labourer, 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 has for its object improvements in or applicable to the bobbins or
spools of the shuttles used in looms for weaving, my improvements being devised with
a view to obviate certain disadvantages arising from the use of the said bobbins or
spools as ordinarily made.
It is usually the custom to wind the worsted or the like, that is to form the weft,
upon a paper spool or cop which is held or retained on the shuttle peg by means of
four springs. This arrangement necessitates that the outer end of the shuttle peg
should be lapped with rosin band or the like to prevent the spool or cop from slipping
on the shuttle peg. Another disadvantage arising from this arrangement is that the
ends of the paper spool or cop are very often rough, and when the shuttle is used
the worsted or the like, that is to form the weft, comes in contact with the rough end
of the paper spool or cop and is thereby frayed and weakened, which often results in
the breakage of the worsted or the like.
Now my invention is intended to obviate the above described disadvantages and at
the same time secure additional advantages by its use.
In order that my invention may be thoroughly understood I have appended the
accompanying sheet of drawings.
Fig. 1 is a plan of a shuttle embodying my improvements.

Fig. 2 is a plan of the bobbin or spool, ready for mounting on the shuttle peg.
Fig. 3 is a vertical section of the bobbin or spool mounted on the shuttle peg.
In these Figures similar letters of reference indicate corresponding parts.
According to my invention I wind the worsted A or the like, that is to form the
weft, upon a paper spool or cop B such as is now used, and I mount the paper spool
B upon a tube C of peculiar formation. The tube C is made of such a diameter
that the paper spool or cop B can be slipped upon it. The outer end of the tube C is
provided with a shoulder D in the inner side of which an annular groove or recess E
is formed. This latter is of such a size as to permit of the paper spool or cop B
being inserted in it but in such a manner that it shall not easily turn on the tube C.
I prefer to place a ring or packing piece F of india-rubber between the inner end of
the paper spool or cop B and the shoulder G of the shuttle peg. The india-rubber
ring serves to press the paper spool or cop B into the annular groove or recess E,
and thus prevent it from slipping or turning on the tube C.
The shuttle peg is of a well-known construction, that is pivotted in the shuttle boly,
and consists of two spring-like arms H, H¹, which press against the inner surface of
the tube C. One of the arms H is provided with a projection h, and this prevents
the bobbin or spool from slipping along the shuttle peg. My invention is primarily
intended to be used in conjunction with this construction of shuttle peg, but it might
be employed in combination with any other construction of shuttle peg to which it
could be conveniently applied.
I prefer that the tabe C should be of metal and I make it separate from the
shoulder D, which is afterwards united to it by means of brazing or soldering. The
tube C may be made of any other hard material such as wood.
By the above described construction of bobbin or spool, the worsted or the like that
is to form the weft, whilst being unwound is entirely raised from the paper spool or
cop and is thereby prevented from coming in contact with the rough end of the paper
spool or cop, so minimising the chance of a breakage of the worsted or the like.

page_text: Another advantage which will accrue from the use of my improved bobbin or spool
is that the spinner by spinning on to the paper spool or cop direct will be able to put
half as much more of the worsted or the like on the paper spool or cop than is possible
in those cases in which a wooden spool or cop is used. Consequently the
worsted or the like will last half as long again when it is put into the shuttle and less
of the worsted or the like will be wasted. A further advantage arising from the use
of my improved bobbin or spool will be that the cost of carriage of the paper spools
or cops will be less than that of the wooden spools or cops.
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 :-
The improved bobbin or spool for the shuttles used in looms for weaving con-
sisting of the ordinary paper spool or cop B which is mounted on a tube C having
a shoulder D which is provided with a recess E within which the outer end of
the paper cop or tube B is inserted, the said tube C being mounted upon a shuttle
peg such as H, H', substantially as and for the purpose described herein and
illustrated by the accompanying drawings.
