Complete Specification Left, 30th Dec., 1898-Accepted, 4th Feb.,
1899
I, HERBERT WILLIAM WILSON, of Wilson Brothers Bobbin Company Limited,
of Cornholme Mills, Todmorden, in the County of York, Bobbin and Shuttle Manu-
facturers, do hereby declare the nature of this invention to be as follows:
My invention relates to improvements in weft pirns, the object of my improve-
ment being to strengthen the head of the pirn so as to increase its durability.
In one method of making my improved pirn, I proceed to make the pirn of
paper or wood of any suitable size and shape, and pass a metal hoop along the
barrel of the pirn until it reaches the head. The hoop is flanged at one end or
it may be at both ends and it may also be made with a bead. I take an ordinary
shield which entirely or partly covers the bottom and periphery of the head of the
pirn and after this shield has been pressed on in the usual manner, I spin it over
the flange of the first hoop, thus locking the shield and hoop securely together, or
alternatively the hoop might be put on after the shield.
Although I have mentioned flanged hoops, plain hoops might be employed, in
which case pressing or shaping tools could be employed to make the hoop the
required shape while being pressed on to the pirn.
As an alternative the hoop might be made of a single piece of metal so as to cover
the whole or part of the bottom of the pirn and extend over the pirn head and a
short distance up the barrel of the pirn, and by means of milling and shaping tools
the hoop may be made to fit the head and barrel of the pirn.
Dated this 29th day of March 1898.

Improvements in Weft Pirns.
I, HERBERT WILLIAM WILSON, of Wilson Brothers Bobbin Company Limited,
of Cornholme Mills, Todmorden, in the County of York, Bobbin and Shuttle Manu-
facturers, 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:-
My invention relates to improvements in weft pirns, the object of my improve-
ment being to strengthen the head of the pirn so as to increase its durability.
In one method of making my improved pirn, I proceed to make the pirn of
paper or wood of any suitable size and shape, and pass a metal hoop along the

page_text: barrel of the pirn until it reaches the head. The hoop is Hanged at one end or
it may be at both ends and it may also be made with a bead. I take an ordinary
shield which entirely or partly covers the bottom and periphery of the head of the
pirn and after this shield has been pressed on in the usual manner, I spin it over
the flange of the first hoop, thus locking the shield and hoop securely together, or
alternatively the hoop might be put on after the shield.
In the accompanying sheet of drawings
Fig. 1 is a drawing of a weft pirn made of paper or wood and Figs. 2 and 3 are
sectional views of the head of the pirn to illustrate my improved means of
strengthening the same.
In the drawings, designates the body of the pirn, and 6 the head or flange,
I take a flanged metal hoop c with or without a bead, and pass it along the barrel
of the pirn until it reaches the head as shown in Fig. 2, I next take an ordinary
hoop or shield d which, in this case, covers the bottom and periphery of the head b,
and after the bottom portion of this shield has been pressed on the head in the
usual manner, I spin its other portion and press it into a flange over the flange
of the hoop c, thus locking the shield and hoop securely together as shown in
Figs. 1 and 3.
If preferred the shield d might be put on and pressed into position first and the
hoop applied afterwards, and in either case the tubular portion of the hoop c
might be turned in and forced into the timber when the final pressing was given to
the hoop.
Although have mentioned flanged hoops c plain hoops might be employed, in
which case pressing or shaping tools could be employed to form a bead if desired
and to make the hoop the required shape while being pressed on to the pirn.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
A weft pirn having a strengthening hoop c combined with a shield d, applied to
its head substantially as illustrated and described.
