Improvements in Shuttle Guards of Looms for Weaving.
I, FREDERICK BAYNES, of Cicely Bridge Mill, Blackburn, in the County of
Lancaster, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
According to this invention, I employ a metal rod hinged to the lower edge of
the reed cap, the said rod having formed upon it, two or more cranks resting in
and being supported by bearings secured to the reed cap. The said cranks form
hinges around which the rod can turn from the inoperative or "off" position in
which it is folded up against the reed cap, to the operative or "on" position over
the shuttle race.
Projections or keys are formed on that portion of the cranked rod which forms
the axis, or is enclosed by the bearings, and such keys or projections form stops
which by the weight of the rod, when in its operative position, are caused to press
against the portion of the bearings provided therefor, thus defining and controlling
the position of the rod.
The frictional device is a small blade spring combined with or attached to the
bearing, and pressing upon the hinge, and there may be interposed between the
spring and the part of the guard upon which it presses, wood, leather or other
material, to gain the friction desired.
The spring bearing on the guard, prevents vibration of the latter, and may be
of sufficient strength to hold the guard in any position, whilst the loom is standing,
but when the loom is in motion, automatically assumes and is held in the operative
position.
Improvements in Shuttle Guards of Looms for Weaving.
I, FREDERICK BAYNES, of Cicely Bridge Mill, Blackburn, in the County of
Lancaster, Cotton Manufacturer, 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 which is semi-automatic in its action, i.e., when
the loom is in motion the guard is "on," or if the loom is standing and the guard is
"off," when the loom is re-started_the_guard will assume the active or "on"
position. The guard is taken "off" or folded close to the reed cap when necessary,
by hand, and if left in this position, the vibration of the going part of the loom

page_text: will cause the guard to assume the operative position. A frictional device is
applied to such guard.
The improved guard can be made at little cost and very compact, and when
folded back does not obstruct the view of the shuttle race.
Such being the nature and object of my 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 the improved shuttle guard, shewing the rod or
guard as cranked at the end or ends, and also the middle (when desirable).
Fig. 2 is a sectional end elevation of the shuttle race and appliances connected
therewith, and having the improved shuttle guard applied thereto, and in the
operative or "on" position.
Fig. 3 is a sectional view of the hinge portion of the guard in the inoperative
position.
Figs. 4, 5, and 6 are sectional views of slight modifications of the hinge portions
of the guards.
According to this invention I employ a metal rod 1 binged to the lower edge of
the reed cap 2, the said rod 1 having formed upon it two or more cranks 3. 3 resting
in and supported by bearings 4 secured to the reed cap 2. The said cranks 3. 3
supported by the bearings 4 form hinges around which the rod 1 can turn from the
inoperative or "off" position (Fig. 3) in which it is folded up against the reed
cap 2, to the operative or "on" position (Figs. 1 and 2) over the shuttle race 5.
Projections 6 are formed upon or attached to the bearings 4, to form stops
against which keys or projections 7 formed on the crank axis 3 inside the bearings 4
are caused to press by the weight of the rod 1, when the rod is in its operative
position, thus defining and controlling the position of the rod 1.
The frictional device is a small blade spring 8 combined with or attached to and
forming part of the bearing 4 and pressing upon the hinge portion of the rod 1,
and there may be interposed, if necessary, between the spring 8 and the part of
the guard upon which it presses, wood, leather, or other material, to gain the
friction desired.
The spring 8 bearing on the guard 1 prevents vibration of the latter, and may
be of sufficient strength to hold the guard in the inoperative position, whilst the
loom is standing; but when the loom is in motion, the guard automatically assumes
and is held in the operative position.
The key or projection 7 on the rod 1 works in the recess or opening 9 between
the lugs 10. 10. In Fig. 3 the pressure of the spring 8 may be sufficient to hold
the rod in the position in which it is set when folded back, and when in the
operative position, the key 7 rests against the stop 6, being a part of the bearing 4,
being held in this position by the frictional contact of the spring 8, which prevents
vibration of the rod 1 when the loom is in motion. In Figs. 4 and 5 the action is
the same, but when the rod 1 has to be moved to the inoperative position, the
key 7 has to deflect the spring 8 and pass under the same. In Fig. 6 two springs 8
and 84 are employed, the end of the spring 84 resting against the key or projection 7
of the rod 1 when the latter is in the operative position. When the rod 1 has to
be moved to the inoperative position, the spring 84 has to be deflected, and before
the key or projection 7 can pass under same, and the rod is held by and between
such springs 8, 8ª.
When the loom is running, in Figs. 4, 5, and 6, the guard 1 when in the
operative position, is held by the key 7 being locked between the spring and the
stop 6, and these forms may be used on quick running looms where there is greater
tendency to vibration.
The key 7 is preferably formed by pressure or punching out of the rod 1, and so
forms a nart thereof

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
(1.) The rod 1, on the axis portions of which are keys or projections 7, the
bearings 4 with stop pieces 6, and springs 8, all in combination, as and for the
purpose herein described, and substantially as illustrated by Figs. 1, 2, and 3 of
the annexed drawings.
(2.) The rod 1, on the axis portions of which are keys or projections 7, the
bearings 4 with stop pieces 6, and springs 8, all in combination, as and for the
purpose herein described and substantially as illustrated by Figs. 4 and 5 of
the annexed drawings.
(3.) The rod 1, on the axis portions of which are keys or projections 7, the
bearings 4 with stop pieces 6, and springs 8, 84, all in combination, as and for the
purpose herein described, and substantially as illustrated by Fig. 6 of the drawings.
