I, THOMAS SINGLETON, of Over Darwen, in the County of Lancaster,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN LOOMS FOR WEAVING AND IN SHUTTLES USED THEREIN," to be as follows:-
The first part of this Invention relates to loose reed looms, and consists
in various improved arrangements of mechanism for making the reed
fast for beating up the weft and loose when the shuttle is lodged in
the shed. To the ordinary stop rod carrying the swell levers or fingers
I fix a front arm connected by a link with a stop finger jointed to a
spring lever attached to one of the sword arms. The reed binder is
connected to bent arms fixed to a rod beneath the slay, which rod can
move to and fro longitudinally, and to the under side of the slay are
fixed brackets which support the bent arms and keep the recd fast when
the rod and arms are kept in one position by the spring lever being in
contact with a boss or projection on the rod. When the shuttle is not
properly boxed the swell levers are not acted upon by the shuttle and
the stop finger jointed to the spring lever is not raised, and as the slay

page_text: advances the finger comes in contact with the frog and causes the top
of the spring lever to be pushed back from the boss or projection and
release the rod, which is pulled by means of a spiral spring, so that the
arms carrying the reed binder shall be removed from the brackets fixed
to the slay and allow the reed to be loose for preventing damage to the
warp.
In another arrangement I fix brackets to the slay or reed cap
carrying perpendicular rods fitted to brackets fixed to the back of the
slay, the said rods having their top or bottom ends in contact with or
connected to back arms fixed to the stop rod carrying the front arm
link and stop finger before mentioned. When the shuttle is not
properly boxed the stop finger comes in contact with the frog and
partly turns the stop rod, the effect of which is to raise the back arms
and also the perpendicular rods and slay cap and reed so as to remove
the bottom of the reed from its seating in the slay and make it loose;
or I place springs on the perpendicular rods and fix to the rods snugs
or projections which are held by arms on the stop rod when the shuttle
is properly boxed, but when the shuttle is lodged in the warp the stop
finger when it comes in contact with the frog causes the arms to be
removed from the snugs and the springs raise the rods, slay cap, and
reed, and make the reed loose. These arrangements may be reversed by
making the slay cap fast and moving the reed binder in the same
manner as the slay cap is raised.
The second part of this Invention consists in various improvements
connected with shuttles used in looms for weaving. Instead of the
ordinary bedding pin for supporting the shuttle tongue I employ a
.square or oblong piece of metal for the bed and use two pins to fix
it to the shuttle. I also place in the shuttle an additional pin for
holding the tube on which the cop is spun or wound, and for the ordinary
shuttle tongue I substitute one formed in a hollow spiral form from
sheet metal.
