PROVISIONAL SPECIFICATION.
Improvements in or connected with Tongues or Pegs for Shuttles
Employed in Looms for Weaving.
I, WILLIAM MCNICHOL, of Chapel Fold, Dewsbury, Yorkshire, Foreman
Tuner, do hereby declare the nature of this invention to be as follows:-
--
My invention refers to those shuttle tongues or pegs whereon the bobbins of
weft are held by means of a button on the end of the tongue and a longitudinal spring.
or springs which, being slightly compressed by the bobbin when pushed home onto.
the peg exert sufficient force or expansive pressure to hold the bobbin in position.
thereon.
These said springs are faulty, causing the bobbins to break at the ends and to
split, and they frequently fail to prevent accidental withdrawal or partial dislodge-
ment of the bobbin from the peg under violent concussion of the shuttle or like
causes. The object of my improvements is to remedy the defects of the springs.
aforesaid, and this I accomplish by employing a double acting spring of suitable
construction which is attached to the bobbin peg or tongue in a somewhat similar
manner to that now adopted for attachment of the ordinary springs.
The spring is constructed longitudinally with two or more arcs or curves adapted.
to engage with the bobbin and with the intermediate portion or portions of said
spring curved in an opposite direction to bear against the tongue or peg, the:
arrangement being such that when one portion thereof is compressed another
portion is expanded, while greater force or pressure is required to compress the
whole spring longitudinally.
By means of the double acting spring or springs a much firmer hold is obtained
on the bobbin, and there is no liability of it being accidentally forced off or with--
drawn from the peg. The bobbin can be as easily placed on and removed from
the tongue as at present.
The pressure of the spring being divided or distributed more equally over the
longitudinal axis or bore of the bobbin, all liability of the bobbins being split or
broken at the ends is prevented.

Improvements in or connected with Tongues or Pegs for Shuttles.
Employed in Looms for Weaving.
I, WILLIAM MC NICHOL, of Chapel Fold, Dewsbury, Yorkshire, Foreman
Tuner, 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 refers to those shuttle tongues or pegs whereon the bobbins of weft.

page_text: are held by means of a longitudinal spring or springs which, being slightly com-
pressed by the bobbin when pressed home on to the peg exert sufficient force or
expansive pressure to hold the bobbin in position.
These said springs are faulty causing the bobbins to break at the ends and to
split and they frequently fail to prevent accidental withdrawal or partial dislodg-
ment of the bobbin from the peg under violent concussion of the shuttle and like
causes. The object of my improvements is to remedy the defects of the springs
aforesaid and this I accomplish by employing a double acting spring of suitable
construction so formed that when one portion thereof is compressed another portion
thereof is expanded, while great force is required to compress the whole spring
longitudinally.
The accompanying drawings illustrate my improved construction of double
acting spring where Fig. 1 is elevation of the shuttle peg and Fig. 2 is also elevation
shewing a bobbin or spool in position where in both cases A. is the shuttle peg and
B the double acting spring. I prefer to make the spring in such a manner that
in putting on a bobbin the first part of the spring B does not rest against the
internal sides of the bobbin C until the bobbin arrives at the second part of the
spring B' which forces the free end of the spring down the recess D, the action of
which forces the front part of the spring B into closer contact with the internal
part of the bobbin whereby the said bobbin is locked and made secure.
By means of the double acting spring or springs as shewn and described a much
firmer hold is obtained on the bobbin and there is no liability of it being accidentally
forced off or withdrawn from the peg. The bobbin can be easily placed on and
removed from the peg as at present.
The pressure of the spring being divided or distributed more equally over the
longitudinal axis or bore of the bobbin, all liability of the bobbin being split or
broken at the ends is prevented.
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 shuttle peg or tongue made with a double acting spring as described and
illustrated in the accompanying drawings.
