Improvements in Shuttle Guards for Looms.
We, JOHN CLEGG, of Stonebridge Works, Colne, in the County of Lancaster,
Weft Fork and Spring Maker, and ROBERT HARTLEY CLEGG, of the same place,
Foreman, do hereby declare the nature of this invention to be as follows:-
-
Our said invention relates to improvements in shuttle guards for looms, used to
prevent the shuttle from flying out of the race as is well understood.
In carrying our invention into effect we screw or otherwise secure a bracket at
each end of the sley. These brackets are provided with bearings for the recep-
tion of the cranked ends of a rod extending along the lower edge of the sley,
which rod performs the function of the shuttle guard. The cranked ends of the
rod project beyond the bearings formed in the brackets and are provided with
spiral springs abutting between the brackets and stops formed in the cranked ends
of the rod. When out of action the rod fits closely against the side of the sley,
and the cranked ends bear against the brackets allowing the weaver to have access
to the shuttle in the race, the springs being then compressed.
The brackets are formed with projections into which are cut inclined recesses
terminating with a stop. On the starting of the loom, at the first forward motion
of the sley the vibration or shock, assisted by the compressed spiral springs, throws
the cranked rod away from the sley and along the inclined recesses formed in the
bracket, until it bears against the stops, in which position it is maintained by the
action of the springs.
In this position the rod overhangs the shuttle race, and guards against the flying
out of the shuttle.
The shuttle guard is thus automatic in its action and does not depend for its
efficiency upon the attention of the weaver. When used in wide looms we
crank the guard rod upwards about the middle of its length and provide a bearing
might
for the same attached to the sley in order to form an additional support for the rod.

page_text: Foreman, 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 and accompanying drawings:
Our said invention relates to improvements in shuttle guards for looms, used to
prevent the shuttle from flying out of the race as is well understood.
In carrying our invention into effect we screw or otherwise secure a bracket at
each end of the slay cap. These brackets are provided with bearings for the recep
tion of the cranked ends of a rod extending along the lower edge of the slay cap,
which rod performs the function of the shuttle guard. The cranked ends of the
rod project beyond the bearings formed in the brackets and are provided with
spiral springs abutting between the brackets and stops formed in the cranked ends
of the rod. When out of action the rod fits closely against the side of the slay cap,
and the cranked ends bear against the brackets allowing the weaver to have access
to the shuttle in the race, the springs being then compressed.
The brackets are formed with projections into which are cut inclined recesses
terminating with a stop. On the starting of the loom, at the first forward motion
of the slay the vibration or shock, assisted by the compressed spiral springs, throws
the cranked rod away from the slay and along the inclined recesses formed in the
bracket, until it bears against the stops, in which position it is maintained by the
action of the springs.
In this position the rod overhangs the shuttle race, and guards against the flying
out of the shuttle.
Our invention will be more clearly understood from an inspection of the accom-
panying sheet of drawings in which:-
Fig. 1 represents a front elevation of our improved shuttle guard secured to the
slay cap of a loom and broken off in length for want of space, the guard being
shown out of action.
Fig. 2 is a plan of Fig. 1 with the guard in action.
Fig. 3 is an end view of the slay cap and guard out of action.
Fig. 4 is an end view showing the guard in action.
Fig. 5 is a perspective view of one of the brackets.
To the slay cap a of the loom we secure brackets 6 by means of screws c or other
suitable means.
The brackets are formed with bearings & within which work the cranked or
bent ends e¹ of the guard rod e.
The ends e¹ of the rod e project through and beyond the bearings formed in the
brackets b, and are provided with compressed spiral springs ff. The springs ff
are compressed between the brackets 6 and stops gg formed on or secured to the
ends e¹ of the rod. When out of action the rod e fits closely against the slay cap a
as shown in Figs. 1 and 3 the springs ff being then under the greatest degree of
compression. The rod e in this position abuts against the straight portion or side h
of the brackets the pull of the springs ff tending to maintain the rod in this posi-
tion. As will be seen from an inspection of Figs. 2 and 5 the brackets b are formed
with inclined recesses i terminating in stops j. When the loom is started, on the
first outward stroke of the slay, the vibration or shock dislodges the rod e from the
side h of the brackets b. The rod e is thus thrown away from the side of the slay
cap a along the incline recesses i until it abuts against the stops j. the pull of the
compressed springs assisting this, and also maintaining the rod in this position.
The rod has then assumed the position indicated in Figs. 2 and 4, overhanging the
shuttle race so as to guard against the shuttle flying out of the race.
The shuttle guard is thus automatic in its action and does not depend for its
efficiency upon the attention of the weaver.
When the loom is stopped for the changing of a shuttle, drawing in varn, un-
weaving cloth or other purposes, the guard rod is readily removed out of the way
by pushing it along the inclined portion h of the brackets 6 against the action of
the springs ff until it bears against the sides h of the brackets and the front of.

page_text: the slay cap a as shown in Figs. 1 and 3 in which position it will remain until the
starting of the loom. When used in wide looms we crank the rod e about the
middle of its length as shown in the drawings and provide a bearing for the same
formed in the bracket k secured to the slay cap a so as to form an additional sup-
port for the rod.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
:-
1. The improved shuttle guard for looms constructed, arranged and acting
in the manner and substantially as described and illustrated.
2. In shuttle guards of the indicated nature the brackets 6 formed with flat sides h
inclines i and stops j such brackets controlling the movements of a cranked rod
operated by springs substantially as described and illustrated.
