PROVISIONAL SPECIFICATION.
Improvement in Shuttle Pegs or Tongues, and Bobbins or Pirns
to Work thereon.
I, ANDREW KYLE, Foreman, Power Loom Tuner, 10 Wilton Hill Terrace,
Hawick in the County of Roxburgh, North Britain, do hereby declare the nature
of this invention to be as follows:-
My invention appertains to shuttle tongues or pegs and bobbins or pirns to
work thereon. The shuttle tongue is made in two parts. Both parts are fixed
in the shuttle with a wire going through a hole in the heel of the tongue in each of
them. The under part works in a spring like the common lift-up-tongue. Both
parts are almost alike. The two parts lie together as ove. There is a swell
marked A on the under side of the under part and also a swell marked A 1 on the
top side of the top part. The swells are inade to fit in the recess marked B in the
pirn or bobbin. There are from two to four sloped notches marked C inside of
both parts for expanding and contracting them. The tongue is lifted up to put on
and take off the pirn. The sloped notches pass each other and the tongue contracts
or becomes smaller. The pirn is put on the tongue then the tongue and pirn are
put down. The sloped notches meet one another and expand the tongue and the
swelled parts go into the recess marked B on the pirn and holds the pirn in its
working position.

COMPLETE PEITIATION.
Improvement in Shuttle Pegs or Tongues, and Bobbins or Pirns
to Work thereon.
I, ANDREW KYLE, Foreman, Power Loom Tuner, 10 Wilton Hill Terrace,
Hawick in the County of Roxburgh, North Britain 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 shuttle pegs or tongues and bobbins or
pirns to work thereon and the chief object of my improvements is to enable a bobbin
or pirn to be securely held in working position on the shuttle-peg and yet to be
readily taken off when required. I accomplish this object substantially in the
manner and by the means illustrated in the sheet of drawings already sent in with
the "Provisional Specification."
Figure 1 is a shuttle fitted with my improved peg and bobbin or pirn.
Figure 2 is a view of the improved shuttle peg or tongue detached.
Figure 4 is a view of the improved bobbin or pirn detached.
The shuttle has its peg or tongue pivoted to it in the usual or any other
convenient way and I prefer to make the tongue in two separate parts the one
lying above the other and both working off a separate wire.
The under part works in a spring like the common lift-up tongue.
The top part has a swell or swells (marked A 1.) or ridges or grooves on the
outside thereof

page_text: The under part has a swell or swells (marked A.) or smooth surface on the
outside thereof.
I may however make the under swell or swells as well as the top swell or swells
any requisite length either way.
The insides of both parts have on them from one to four notches or protuberances
marked C. for expanding and contracting both sides.
The notches or protuberances are opposite each other and they come together
when lying horizontally.
When raised as shewn in Figure 3 to put on the pirn the sloped notches pass
each other and reduce the expansion of the tongue or peg and the pirn is thus
easily taken off.
The full pirn is put on with the tongue or peg in the same position. Then it is
put down into the shuttle.
The sloped notches meet each other and expand the two parts which thus hold
the piru securely in a working position.
The pirn or bobbin has a recess marked B (in Figure 4). I may however make
the recess any suitable length.
The entrance to the recess may be bushed with an iron or brass or any
other suitable metal bush to prevent the pirn coming off through ordinary tear
and wear.
I may however make the pirn with the hole narrower at the entrance and wider
towards the point or small part of the pirn so that when the tongue is lifted up for
the pirn going on the two parts of the tongue are contracted or become smaller and
in the action of puting down the bobbin or pirn into the shuttle the notches or
protuberances meet and expand thus fixing the tongue or peg in the pirn holding
it firmly and preventing its coming off when in its working position.
The tongue made in two parts as aforesaid can also work with the pirn having a
straight hole presently in use.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is:-
1. The improved shuttle peg furnished with swells or protuberances ridges or
grooves or smooth and the notches for expanding and contracting for holding the
pirn on the peg or tongue substantially in the manner herein set forth.
2. The combination of the shuttle peg or tongue made in two parts getting the
one to pass the other by the action of lifting them up.
.
3. The improved bobbin or pirn furnished with a small metal bush and recess
beyond the metal bush and a tapered hole in the pira and the tongue made in two
parts with the notches for contracting and expanding with the action of lifting
them up and puting them down and thus locking the pirn in the tongue and
bolding it firmly in its working position all substantially in the manner herein
set forth.
4. The combination with the shuttle peg and hobbin or pirn having a recess and
metal bush at the end of the recess or pirn with a tapered hole and the tongue or
peg made in two parts can also be worked with the present pirns in use having a
straight hole.
