page_text: We, GEORGE WHITTAKER HARGREAVES, of No. 37 Brookhouse Lane, Blackburn,
Tinplate Worker, and ROBERT HARGREAVES, of No. 32 Brookhouse Lane, Black-
burn, in the County of Lancaster, Tinplate Worker, do hereby declare the nature
of this invention to be as follows:-
This invention relates to improvements in shuttle guards of looms for weaving,
the object being to construct a guard both simple and efficient, and one which is
to be put in the inoperative position by hand, but it will automatically resume the
active or "on" position as soon as the loom is started.
According to this invention, we employ a rod of metal extending from end to
end of the shuttle race and hinged at about its centre to the reed cap. At
each end of the reed cap is a bracket in which is formed a curved slot, and the
ends of the rod are received in these slots, buttons being fixed on the ends of the
rod outside the brackets.
At the bottom and top of the slots are slight recesses or hollows in which the
rod can rest.
When the shuttle guard is inoperative, the rod is folded on its hinge close
to the reed cap, the ends of such rod resting in the recesses at the top of the
slots. When the loom is started, the vibration causes the rod to jump out of the
top recesses and fall down the slots into the bottom recesses where steps or pro-
jections prevent the rod rising if struck by the shuttle, but the spring in the rod
allows the latter to be readily raised by hand when the guard is to be put "off"
or inoperative.

page_text: burn in the County of Lancaster, Tinplate Worker, 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 shuttle guards of looms for weaving,
the object being to construct a guard both simple and efficient, and one which is
to be put in the inoperative position by hand, but it will automatically resume the
active or "on" position as soon as the loom is started.
According to this invention, we employ a rod of metal extending from end to
end of the shuttle race and hinged at its ends or about its centre to the reed cap.
'At the centre or near each end of the reed cap is a bracket in which is formed a
curved slot, and the rod is passed through the slot or slots. At the bottom of the
slots are slight recesses or hollows in which the rod can rest.
When the shuttle guard is inoperative, the rod is folded on its hinge or hinges
close to the reed cap and when the loom is started the guard automatically assumes
the active or operative position.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which :-
Fig. 1 is a front elevation of a reed cap and shuttle guard constructed according
to this invention.
Fig. 2 is a view of a modified form of Fig. 1.
Fig. 3 is an end sectional elevation of Figs. 1 and 2.
Fig. 4 is a similar view to Fig. 3, drawn to an enlarged scale.
According to this invention we employ a rod of metal 1 extending from end to
end of the shuttle race and cranked and hinged at about its centre 2 to the reed
cap 3. At or near each end of the reed cap 3 is fixed a bracket 4 in which is
formed a curved slot 5, and the ends of the metal rod 1 are received in these slots 5,
buttons 6, 6 being fixed on the ends of the rod 1 outside the brackets 4 and slots 5.
At the bottom of the slots 5, 5 are slight projections 7 which form recesses or
hollows 8 in which the rod 1 can rest.
In Fig. 2 the rod 1 is shewn as cranked and hinged at each end 2, 2 to the reed
cap 1, and the bracket 4 is fixed about the centre of the reed cap 3, a modification
which we have found in practice to work satisfactorily. The action and mode of
operation of both the guards is similar.
The action is as follows:-When the shuttle guard is inoperative, the rod 1
is by hand folded or turned upwards on its hinge or hinges 2, 2 so as to lie close
to the top of the reed cap 3, the ends (see Fig. 1) or centre (see Fig. 2) of the rod 1
resting on the straight part 9 of the slot 5 in and near the top of the brackets or
bracket 4. When the loom is started the vibration causes the rod 1 to fall down
the slot or slots 5 into the bottom recess or recesses 8 and the projections 7 prevent
the rod 1 rising if struck by a shuttle. The spring or elasticity of the rod I allows
the latter to be easily and readily raised by hand when the guard is to be put "off"
or in the inoperative position.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed I declare that what I
claim is:-
(1) The general construction, arrangement, and combination of parts con-
stituting the improved shuttle guard as herein described and substantially as
illustrated by the annexed drawings.
(2) A metal rod hinged to the reed cap combined with brackets having slots
with recesses or hollows at their lower ends as and for the purpose herein described
and substantially as illustrated by Fig. 1 of the accompanying drawings.
(3) A metal rod hinged to the reed cap combined with a bracket in which is a

described and substantially as illustrated by Fig. 2 of the annexed drawings.
