IMPROVED AUTOMATIC SHUTTLE GUARDS FOR Looмs
Year: 1885

page_text: I ROBERT SMYTH, Tullyelmer Armagh, Co. Armagh, Ireland Linen Manufacturer
do hereby declare the nature of the said invention for IMPROVED AUTOMATIC
SHUTTLE GUARDS FOR Looмs to be as follows:-
This invention has for its object the prevention of shuttles flying out, when the
looms are in operation, whereby the operatives, are in much danger of meeting with
serious accidents, such as the losing of an eye, and other disfigurements of the
face &c; also much damage is often done to the cloth being woven.
I accomplish my object by placing a bar from one slay sword to the other, on
this bar is attached all the shuttle guard's connection, viz, two curved brackets or
carriers, one on each end, which come up at the back of the slay; the curves pass
under the handrail and stand out in front of the reed, the necessary distance to
cover the slay race, when the loom is in operation: into these brackets or carriers
is rivetted one two or more rods as required; which compose the effectual and
perfect shuttle guard. When the loom is stopping, by a simple mechanical arrange-
ment, the guard moves in close to the reed and under the handrail, which leaves it
almost invisible and is completely out of the workers way. When the loom is
again in operation the guard moves forward over the slay race, so that the shuttle
cannot fly out.

turer do hereby declare the nature of the said invention for IMPROVED AUTOMATIO
SHUTTLE GUARDS FOR LOOMS and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
This invention has for its object the prevention of shuttles flying out, when the
looms are in operation, whereby the operatives are in much danger of meeting with
serious accidents, such as the losing of an eye and other disfigurements of the
face and so forth; also much damage is often done to the fabric being woven.
I accomplish my object by placing a bar from one slay sword to the other; on
this bar is attached all the shuttle guard's connections, viz, two curved brackets or
carriers, one on each end which come up at the back of the slay, the curves passing
under the handrail at each end of the reed the necessary distance to cover the slay
race, when the loom is in operation. Into these brackets or carriers are rivetted
one two or more rods as required. The rod or rods lie parallel with the reed and
compose the effectual and perfect shuttle guard. When the loom is stopping by a
simple mechanical arrangement the guard moves in close to the reed and under the
handrail, which leaves it almost invisible and is altogether out of the workers way:
when the loom is again in operation the guard moves forward over the slay race, so
that the shuttle cannot fly out.
DESCRIPTION OF DRAWINGS.
Figure. 1. a is the handrail and B the shuttle box, c is the guard in position when
the loom is in motion, as shewn in Figure. 3: the dotted lines D shews the guard
when the loom is at rest, moved back to the reed and under the handrail, to be out
of the workers way when tying yarn &c, as shewn in Figure. 2. E is the bar
attached to the slay swords on which the carriers and lever are connected.
Figure. 4. is a notch bracket attatched to the rocking rail of the slay.
Figure. 5. is a hook lever attached to the loom handle which acts on the lever a,
as the loom is stopping and brings it into the position shewn in Figure. 2. and
when the loom is again starting the lever a, is moved into the position shewn in
Figure. 3.
A peculiarity about this guard is, that it is in no way attached to the loom handle
and is perfectly steady, simple, and effectual.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
A shuttle guard for looms with an inward and outward motion; also the curved
brackets or carriers B, the bar E, the lever a, and the lever H, as described in the
drawings.
