COMPLETE SPECIFICATION.
Improvements in Shuttle Pegs and Bobbins or Pirns to Work
thereon.
We, THOMAS FINLAYSON MACKISON and EDWARD TATTERSALL, both of
Bamford, near Rochdale, in the County of Lancaster, Cotton Spinners and
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:-
Our invention relates to improvements in shuttle pegs and bobbins or pirns to
work thereon, and the chief object of our improvements is to enable a bobbin or
pirn to be securely held in position on the shuttle-peg, and yet to be readily doffed
when required.
We accomplish this object substantially in the manner and by the means
illustrated on the accompanying sheet of drawings in which-
Figure 1 is a side elevation, partly in section, of a shuttle fitted with our improved
peg and bobbin or pirn.
Figure 2 is a view of the improved shuttle detached.
peg
Figure 3 is a view, partly in section, of the improved bobbin or pirn detached.
The shuttle a has its peg or tongue b pivoted to it in the usual or any convenient
way and we prefer to make the top spring & as shown, that is to say, brazed or
otherwise secured to the peg at its outer end but free and slightly curved upward
at the heel or head end. We may however make the top spring of any other
suitable shape and construction.
We form a nick or recess 62 in the peg near the heel and on the side opposite
to the spring . On the bobbin or pira c we secure a metal end or collar d with a
central hole corresponding with but of smaller diameter than the central hole c¹ in
the bobbin or pirn e whereby an annular ledge d' is formed as clearly shown in
Fig. 3.

page_text: When the bobbin or pirne is put on the peg the spring b¹ forces the ledge d'
into the nick 2 and thereby firmly holds and locks the bobbin or pirn c in its place.
To doff it is only necessary to press the bobbin or pirn e so as to force the spring b¹
in toward the peg band simultaneously move the ledge d' out of the nick and so
release the bobbin or pirn c which can be then drawn off the peg.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The improved shuttle peg furnished with a spring on one side and a nick
or recess on the other side near its head or heel to engage and leck a bobbin or
pirn on to the peg substantially in the manner herein set forth.
2. The improved bobbin or pirn furnished with a metal end or collar forming
an inner annular ledge to receive and engage a nick or recess on a shuttle peg
substantially in the manner herein set forth.
3. The combination with a shuttle peg having a spring on one side and a nick
or recess on the other side near its head or heel, of a bobbin or pirn having a metal
end forming an annular ledge to engage said nick or recess substantially as and for
the purposes herein described with reference to the accompanying drawings.
