Improvements in Shuttle Guards for Looms.
We, ARTHUR TRAVIS CLAY, of Crow Trees Mill, Rastrick, in the County of
York, Manufacturer, ARTHUR CROWTHER, Mill Manager, and THOMAS LEECH
RAMSDEN, Assistant Loom Tuner, both of the same place, do hereby declare the
nature of this invention to be as follows:-
In constructing a shuttle guard according to our invention we fix three or other
suitable number of brackets to the hand rail of the loom, and to these brackets we
hinge a grate or pivoted rectangular frame composed of cross bars arranged at
right angles. The pivoted frame occupies a horizontal position under the hand
rail extending over the shuttle race and when in its normal position will prevent a
shuttle from flying out.
When the weaver desires to examine the "shed" for broken ends or other
reasons, the pivoted frame forms no impediment as by a touch of the hand the
frame will collapse or close up to the width of one bar, and as soon as the loom is
set on the motion of the slay will throw the pivoted frame into position again.

COMPLETE SPECIFICATION.
Improvements in Shuttle Guards for Looms.
We, ARTHUR TRAVIS CLAY of Crow Trees Mill, Rastrick, in the County of
York, Manufacturer, ARTHUR CROWTHER Mill Manager, and THOMAS LEECH
RAMSDEN Assistant Loom Tuner, both of the same place 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 :-
Our invention relates to guards for preventing the shuttles flying out of
the loom.
In constructing same according to our invention we fix three or other suitable
number of brackets to the hand rail of the loom, and to these brackets we hinge a
grate or pivotted rectangular frame composed of cross bars arranged at right
angles. The pivotted frame occupies a horizontal position under the hand rail,
extending over the shuttle race, and when in its normal position will prevent a
shuttle from flying out.
When the weaver desires to examine the "shed" for broken ends, or other
reasons, the pivotted frame forms no impediment, as by a touch of the hand, the
frame will collapse or close up to the width of one bar, and as soon as the loom is
re-started, the motion of the slay will throw the pivotted frame into position again.
In order that our invention may be fully understood, reference is hereinafter
had to the annexed sheet of drawings, wherein :-
Fig. 1 is front elevation of our improved shuttle guard attached to the hand
rail of the "slay" or "going part" of the loom and occupying its natural position
for preventing the shuttle from flying out.
Fig. 2. is end elevation of same.

page_text: Fig. 3. is similar elevation to Fig. 1 shewing the shuttle guard closed up out of
the way.
Fig. 4 is plan view of Fig. 1.
The shuttle guard comprises a grate or rectangular pivotted frame constructed
of a number of bars a hinged or centred at 6 to brackets c bolted to the hand
rail d of the slay or "going part" of the loom, and of two or more longitudinal
bars e hinged or pivotted at ƒ and g to each of the bars a, and extending across
the loom. The brackets c have slots h therein to allow of adjustment and to adapt
them to fit different hand rails.
The bars a are preferably cranked downwards towards the front as shewn.
The pivotted frame or guard above described occupies a horizontal position under
the hand rail, extending from the front thereof over the shuttle race when in its
normal or natural position, as shewn in Figs. 1, 2 and 4, and having a complete
command over the exposed length of the shuttle race. The guard, when open, is
held by a spring finger i engaging with the end of central bar a to prevent
oscillation of same through vibration of the loom.
Should a shuttle, in travelling across the running board or shuttle race, rise or
be thrown up through any cause, it will strike against the guard or rectangular
frame and being unable to pass therethrough, its flight is thereby arrested and it
will fall back onto the "shed" or shuttle race.
When the weaver desires to examine the "shed" for broken ends or get near the
reed for any purpose, the shuttle guard offers no impediment, as, by a slight
pressure of the hand from any part of the loom, the frame moving upon its several
centres will close up out of the way to the width of one bar, as shewn in Fig. 3
and in dotted lines in Fig. 4. In restarting, the throw of the loom or beat up of
the slay will cause the guard to return to its natural position over the shuttle race
which position it always maintains, except when purposely closed, without any
attention on the part of the weaver. Stop pieces k limit the motion of the pivotted
guard when closed up either to one side or the other.
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 :-
In looms for weaving, the improved shuttle guard consisting of a jointed
rectangular grate or frame hinged horizontally to brackets bolted to the hand rail
and constructed of longitudinal bars e hinged or pivotted to short bars such as a
each adapted to close one over the other and arranged and acting in the manner
and for the purposes substantially as herein shewn and described.
