We, ELIJAH DIXON, of 29 Charnock Street, Preston, in the county of Lancaster,
Woollen Merchant, and HENRY CLAYTON, of 4 St. George's Terrace, in the same
town, Waste Dealer, 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 connected with shuttles used in looms for
weaving whereby the weft may be broken and the loom stopped when the shuttle
mects a "float" or other obstruction in the shed and consists in providing the shuttle
at or near its upper side with a spring which sinks or gives way under the pressure of
any obstruction in the shed the downward movement of the spring causing a pivotted
arm within the shuttle to be set in motion and brought round near to the point of the
shuttle peg so that the weft may be caused to wrap itself into a hook on the vertical
end of the pivotted arm and thereby be broken.
In the accompanying Drawings
Fig. 1 is a side view (partly in section),
Fig. 2 is a plan, werd
Fig. 3 a side view (partly in section and seen from the opposite side to that in
Fig. 1) of a loom shuttle to which our invention is shewn applied.
Fig. 4 shews in end view the arrangement of parts connected with the pivotted arm,
and
Figs. 6 and 7 are side and plan views respectively of the spring detached.
In the several figures A is the shuttle to which the spring s is affixed at b. The
spring s is formed with a curved part e and the two upper edges of the shuttle are
recessed or hollowed opposite the curved part c of the spring so that the float or other
obstruction may sink into the recessed or hollowed part and thereby depress the spring
|which in its normal position has its highest point c preferably in line with the upper

Figs. 6 and 7 are side and plan views respectively of the spring detached.
In the several figures A is the shuttle to which the spring s is affixed at b. The

which in its normal position has its highest point c preferably in line with the upper
face of the shuttle A. The free end of the springs is made with a forked slot f
(preferably in the form shown at Figs. 6 and and in section at Fig. 4) which grips

the bottom of which projects the arm e formed at its vertical outer extremity with the
hook g. The pivotted bar, arm, and hook as above described when the spring is in its
normal position (that is to say when not depressed) fit into and are held securely
within a suitably formed recess in a metal frame j which may conveniently be fastened
to the lower part of the shuttle by a transverse pin o passed through the shuttle and
through a hole in the projecting part p of the metal frame j. When the spring s is
depressed the downward movement of the fork upon the twisted bar d will cause it
to be rotated and the projecting arm e and hook g to be brought round to the position
shewn in dotted lines in Figs. 1, 2, and 3 whereupon the weft w will fly into the
hook g and be broken thereby causing the ordinary "weft knocking-off lever" to be
actuated and the loom to be stopped in the usual manner as will be well understood.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we claim is :-
In a shuttle used in looms for weaving the use or employment of a spring arranged
to operate a pivotted arm in manner substantially as described and shewn in the
drawings for the purpose set forth.
