PROVISIONAL SPECIFICATION.
Improvements in Loom Shuttles.
We JOHN DUCKWORTH of 127 Whalley New Road, Cotton Manufacturer, and
JOHN EDWARD NUTTALL of 253 Whalley Range, Overlooker both of Blackburn
in the County of Lancaster, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in the construction of loom shuttles,
the objects of the invention being to improve the means of mounting the tongue or
peg in the shuttle, whereby the pin upon which the tongue usually turns is
dispensed with; there is therefore one hole less through the shuttle which is
consequently not so liable to split, and the tongue itself wears much longer and
is much steadier than heretofore.
According to this invention the butt end of the tongue or peg is not pierced
with a hole at all, but is filed or cut away at each side so as to leave a rounded
block or shoulder projecting, which works at each side in a curved metal bearing
or jaw which is fixed inside the shuttle by means of two pins. The jaw is made to
fit the rounded part or shoulder on each side, so that the butt end of the tongue or
peg works freely therein. The lower side at the back of the butt end is left
square or angular so as to work against the usual spring and hold the tongue or
peg in either position in the ordinary manner.

Improvements in Loom Shuttles.
We JOHN DUCKWORTH of 127 Whalley New Road, Cotton Manufacturer, and
JOHN EDWARD NUTTALL of 253 Whalley Range, Overlooker, both of Blackburn,
in the County of Lancaster, 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 relates to improvements in the construction of loom shuttles, the
objects of the invention being to improve the means of mounting the tongue or peg
in the shuttle, whereby the pin upon which the tongue usually turns is dispensed
with; there is therefore one hole less through the shuttle which is consequently
not so liable to split, and the tongue itself wears much longer and is much steadier
than heretofore.
The nature of our invention and the manner in which the same is to be performed
will be readily understood on reference to the sheet of drawings hereunto annexed
and the following explanation thereof.
Fig. 1 is a longitudinal section and Fig. 2 a plan view of an ordinary loom
shuttle for cops, with our improvements shown as attached thereto,

page_text: Figs. 3 and 4 are side and plan views of our improved shuttle peg drawn full
size, and
Fig. 5 is a plan view showing the adaptation of our invention to a shuttle
constructed to carry a pirn.
a is the body of the shuttle and 6 the peg.
According to our invention the butt end of the tongue or peg b is not pierced
with a hole at all (as usual) but is filed or cut away at each side so as to leave a
rounded block or shoulder 6+ (see Figs. 3 and 4) projecting at each side which
works in a curved metal bearing or jaw c (see Figs. 1 and 2) which is fixed inside
the shuttle by means of a pin d, being also held in place by means of the ordinary
spring e which is kept in position (as usual) by the pin f.
The curved jaw c is inade to fit the rounded part or shoulder 6+ on each side so
that the butt end of the tongue or peg b works freely therein. The lower side at
the back of the butt end is left square or angular as shown at *(Fig. 3) so as to
work against the usual spring e and hold the tongue or peg b in either position in
the ordinary manner.
which
The rounded blocks or shoulders + may be made solid or (if preferred) may
be cored out for the sake of lightness as shown by the dotted circle on Fig. 3.
For shuttles intended to be used with pirns the curved horns or catches
hold the flanges of the pirns are preferably cast in one piece with the curved metal
bearing or jaw c as shown at Fig. 5.

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 :-
The combination of the rounded side blocks or shoulders b+ on the butt end
of the shuttle tongue with the curved metal bearing or jaw c substantially
as and for the purposes herein before set forth and illustrated by the drawing
annexed.
