Improvements in Shuttle Guards of Looms for Weaving.
I, JOHN WILLIAM BANISTER of Duke Street Mill, Duke Street, Blackburn
in the County of Lancaster Manager, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in shuttle guards, or appliances designed
for preventing the shuttle flying out of the race, the object being to provide a guard
which remains "on" or in the "safe" position so long as the loom is in motion, and
which can be folded close to the reed cap and out of the way of the weaver when
desired, and when the loom is stopped or "knocked off," but at the first pick of the
loom the guard automatically resumes the "safe" position i.e. is acting.
According to this invention I employ a guard consisting of a rod of metal cranked
at its ends and hinged to the reed cap, on or near one end (or both ends) of the
guard is fixed a star wheel, collar, or disc having one or more flat sides and a blade,
or spiral spring presses against one flat surface and maintaining the guard in the
safe or active position.
By folding the guard close to the reed cap the star wheel disc, or collar is also
partly turned and the spring is compressed and pressing against the plain or round
part of the disc, star wheel or collar and the guard is held-in the folded position
thereby.. At the first pick of the loom the vibration causes the guard to jump or
move back to its working or safe position where it is firmly held by the action of
the spring on one of flat surfaces.
When a spiral spring is employed it may be carried in a recess in the reed cap
and its end covered and protected by means of a metal cap which is pressed against
the star wheel, collar or disc.
For holding the guard in the folded position i.e. close to the reed cap I employ
a sliding bar or lever fixed to the front of the reed cap in such a manner that the
weaver can fasten the guard close to the reed cap; and out of the way whilst
putting in headings.
For the purpose of slightly turning the guard on its hinges at the "beat up "of
the slay I employ a small bracket fixed to one or both ends of the temple trough
with which brackets the guard comes into contact when the reed is close up to the
cloth and the guard is pressed back slightly, sufficient to prevent it striking the
hands of the weaver, if on the temple roller and also from knocking the shuttles off
the cloth where they are often placed by the weaver.

Improvements in Shuttle Guards of Looms for weaving.
I JOHN WILLIAM BANISTER of Duke Street Mill, Duke Street, Blackburn
in the County of Lancaster, 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 improvements in shuttle guards, or appliances designed
for preventing the shuttle flying out of the race, the object being to provide a guard

which remains “, on or in the safe.position so long as the loom is in motion, and
which can be folded close to the reed cap, and out of the way of the weaver when
desired, and when the loom is stopped or "knocked off" but at the first pick of the
loom the guard automatically resumes the "safe" position i.e., is acting.
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 the improved shuttle guard in the active or working
position.
"
Fig. 2 is a sectional end elevation of Fig. 1 the guard being shewn " on or in
the active position.
Fig. 3 is a sectional end elevation of the guard, a spiral spring being employed in
lieu of the blade spring shewn in Figs. 1 and 2 and the guard is on this fig. shewn
as folded close to the reed and out of the way of the weaver.
Fig. 4 is a detail of hinge for the centre of the guard rod to be employed on
wide looms.
According to this invention I employ a guard consisting of a rod of metal 1
cranked at its end 2. 2 and hinged at 3. 3 to the reed cap or hand rail 4. On or
near one end (or both ends) of the guard is fixed a star wheel, collar or disc 5
having one or more flat sides 6 and a blade spring 7 (see Figs. 1 and 2) presses
against the flat surface 6 and maintains the guard 1 in the safe or active position
as shewn by Figs. 1 and 2.
When a spiral spring 7 (see Fig. 3) is employed it is carried in a recess 8 in
the reed cap 4 and its outer end is covered and protected by means of a metal cap 9
which is pressed against the star wheel, collar or disc 5.
By folding the guard 1 close to the reed cap 4 the star wheel, disc, or collar 5 is
also partly turned and the spring 7 is compressed and pressing against the plain or
round part or the corner or angle of the disc, star wheel or collar 5, (see Fig. 3)
the guard is held in the folded position thereby. At the first pick of the loom
the vibration causes the guard 1 to jump or move back to its working or safe
position (see Figs. 1 and 2) where it is firmly held by the action of the spring 7 on
the flat surface 6.
For holding the guard 1 in the folded position i.e. close to the reed cap 4 (see
Fig. 3) I employ a sliding bar bolt or lever 10-fixed to the front of the reed cap 4
and in such a manner that the weaver can by sliding the bolt 10 fasten the
guard 1 close to the reed cap 4 and out of the way whilst putting in beadings
or for other purpose.
In wide looms where the rod 1 is longer, it is sometimes necessary to employ a
third hinge or support 3 (see Figs. 1 and 4) to steady and support the rod 1 and
in this case the said rod 1 is cranked at about its centre 11 and hinged to the reed
cap 4.
In order that the third hinge or support 3 can be fixed after the rod 1 is
cranked I employ a support such as is illustrated by Fig. 4 wherein a block 12 is
first placed against the reed cap 4 and between the latter and the rod 1, then over
the rod 1 and block 12 is fixed the cap 13 in the interior or which are slight recesses
for the reception of corresponding vanes 14, 14 in the block 12 so that the latter is
securely held in position.
"
It will be seen that the ground is always "on or in the active position unless
folded close to the reed, and if in the latter position the first movement of the loom
will at once shake or jerk the guard into the active position.
In order to prevent the guard 1 moving outwards beyond a given point a
stop piece 15 is provided and which comes into contact with the reed cap or a
stud 16 fixed therein.
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

page_text: the improved shuttle guards as and for the purpose herein described and substan-
tially as illustrated by Fig. 1 of the annexed drawings.
2. The rod 1, star wheel, collar or disc 5 and spring 7, the rod 1 being cranked
as at 11 and supported by a hinge consisting of the block 12 and cap 13, all in
combination as and for the purpose herein described and substantially as illustrated
by the annexed drawings.
3. The rod 1, star wheel, collar or disc 5 and spring 7 all in combination as
and for the purpose herein described and substantially as illustrated by Figs. 1, 2
and 3 of the annexed drawings.
