Improvements in Shuttle Guards of Looms for Weaving.
I, JOHN WILLIAM BANISTER of 20 Holland Street off Shear Brow Blackburn,
Cotton Weaving Mill Manager, do hereby declare the nature of this invention to
be as follows:
It consists of an arrangement, of bracket, lever, and upright rod, adapted to the
working of a shuttle guard for looms.
The shuttle guard to consist of a curved metal rod hinged to slay cap, and
passing in front of reed, and kept at sufficient distance from the reed and yarn,
when loom is working, so as not to interfere with the free motion of the shuttle,
except the shuttle rises out of place, when the rod prevents the shuttle from flying
out of loom. This is the shuttle guard proper.
A rod is hinged to the metal guard at the driving side of loom, and this passes
down the back of the shuttle box, to which it is affixed by a suitable fixing.
An adjustable bracket fixed to the spring handle gives motion to a lever, which
is fixed to and underneath the shuttle box, this lever in turn, gives an up and down
motion to rod behind the shuttle box, which in turn raises or depresses shuttle
guard.
When the spring handle is pushed on, and the loom thus set in motion, the lever
drops and allows the rod behind shuttle box, to fall, thus raising shuttle guard,
and placing it in position; this motion is assisted by a spring on slay cap pressing
on bent portion of shuttle guard, when the spring handle is off and the loom con-
sequently stopped, the rod behind shuttle box raised thus depressing the shuttle
guard, and placing it in such a position as not to interfere with the weaver
changing shuttles or drawing in yarn.

COMPLETE SPECIFICATION.
Improvements in Shuttle Guards of Looms for Weaving.
I, JOHN WILLIAM BANISTER of 20 Holland Street off Shear Brow Blackburn
in the County of Lancaster Cotton Weaving Mill Manager, 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 an improved construction, arrangement and combination
of bracket, lever, upright rod, and connections adapted for operating and controlling
the shuttle guard of looms for weaving.
The shuttle guard consists of a curved metal rod hinged to the slay cap, and
passing in front of the reed and maintained at a short distance therefrom when the
loom is working, so as not to interfere with the free motion of the shuttle except
the latter rises out of place when the rod prevents the shuttle from flying out of
the race.
According to this invention a rod is hinged or connected to the metal guard at
the driving side of the loom and this rod passes down close to the back of the
shuttle box.
An adjustable bracket fixed to the spring handle gives motion to a lever which
is mounted underneath the shuttle box aud this lever in turn gives an up and

page_text: down motion to the rod behind the shuttle box which rod raises or depresses the
shuttle guard putting it " or in the active position when the loom is started
"
on
وو
and moving it "off" or close into the reed when the loom is "knocked off."
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.
thereto.
is a front elevation of part of a loom having my improvements applied
Fig. 2 is an end view of Fig. 1.
Fig. 3 is a plan view of part of Fig. 1.
According to this invention a cranked rod forming the shuttle guard is hinged
at its ends to the hand rail 2. One end 3 of the cranked rod 1 is bent or curved
over the top of the hand rail 2 and connected or hinged to a pendant rod 4
supported by a bracket 5 fixed to the back of the hand rail 2 or to the back of
the shuttle box. The lower end of the pendant rod 4 rests on a cranked lever 6
carried by and free to rock on its bracket 7 fixed to the underside of the slay. An
adjustable bracket 8 is by set screw or bolt fixed to the ordinary stop or spring
handle 9.
The action is as follows:-When the handle 9 is moved to stop the loom the
adjustable bracket 8 coming in contact with the end 10 of the cranked lever 6 the
latter is turned in its bracket 7 and the end 11 of the said cranked lever is slightly
raised carrying with it the pendant rod 4 which will raise the curved end 3 of the
rod 1 so that the latter turns in its hinges and is folded close to the reed and out
of the way of the weaver.
When the handle 9 is moved in a 'reverse direction
i.e. to set the loom in motion, the adjustable bracket is moved away from the end 10
of the lever 6 and the weight of the latter turning in its bracket 7 together with
the pendant rod 4 will pull down the curved end 3 of the rod 1 so that the latter
turns in its hinges and the guard moves into the active position as shewn by
Figs. 1 and 2.
A boss 12 is fixed on the rod 1 preferably near to one of the hinges or
brackets, and one side 13 of this boss 12 is flat (see Fig. 2) and against the flut
side there bears the end of a blade or spiral spring 14 fixed to the hand rail 2.
The spring 14 pressing on the flat surface 14 holds the guard steady when on or
active and when the guard is moved off the spring rests against the corner or
round part of the boss so the guard is
put on easily.
"
The guard can be moved "off" or close to the reed by the weight of the
connections if the adjustable bracket 8 is fixed at the opposite side of the stop
handle 9 to that shewn in the drawings i.e. the action of the guard can be made
positive in either direction.
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 general construction arrangement and combination of parts constituting
the improved apparatus for operating and controlling the shuttle guards of looms
for weaving as herein fully described and as illustrated by the accompanying
drawings.
2. The cranked rod or guard 1 connected to the pendant rod 4 the cranked
lever 6 bracket 8 and spring handle 9 all in combination as and for the purpose
herein described and substantially as illustrated by the accompanying drawings.
