PROVISIONAL SPECIFICATION.
Improved Means or Apparatus for Preventing Shuttles Flying Out
of Looms.
I, JOHN CLAYTON of Adland Street, Burnley, in the County of Lancaster, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention is designed to prevent shuttles flying out of looms.
I am perfectly aware that various attempts have been made to accomplish this
desirable object, but such appliances have hitherto failed by being in the way of the
weaver on taking up broken ends, and in putting in and taking out of the box the
shuttle; and further that such appliances, projecting over the yarn a distance from
the reed, and travelling backwards and forwards with the same, will necessarily be
carried at each stroke of the sley over the woven fabric, and should the weaver for
the time being attempt to pick off broken warp threads from the fell of the cloth, he
would most certainly be struck by the protruding or projecting appliances. These
serious objections counterbalance any advantages that would otherwise be derived
from the application of such devices; the weaver preferring to run the risk of being
struck by the shuttle "flying," which is most serious and dangerous, rather than
submit to the inconveniences such appliances usually entail.
66
To obviate these serious difficulties, and at the same time prevent the shuttle
flying" is the object of the present invention.
The first part of my invention consists in placing a rod or bar preferably behind the
reed, and so arranged in position and actuated, as to traverse with the reed, and
follow in close proximity above the warp or the varying angle of the shed of such
warp, that the warp threads in front of the reed may offer the greatest possible
resistance to the shuttle rising, flying out, or leaving the sley.
The second part of my invention consists of a number of pins or studs parallel with
the reed; but at such a distance from it as to allow the shuttle to pass and at the same
time keep it in a direct course; and for this purpose the pins or studs are preferably
made to slide vertically in holes formed in the sley and so as to project into the shed
during the traverse of the shuttle.
The third part of my invention consists of a rod or guard assuming, a position in
front of the reed, say a distance of two inches during the traverse of the shuttle
through the shed, but so actuated as to fall against the reed immediately under
the reed baulk. This may be effected by the employment of radius rods or arms.
Dated this 11th day of October 1889.

COMPLETE SPECIFICATION.
Improved Means or Apparatus for Preventing Shuttles Flying Out
of Looms.
I, JOHN CLAYTON of Adland Street, Burnley, in the County of Lancaster, Engineer,
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 is designed to prevent shuttles "flying out" of looms. I am
perfectly aware that various attempts have been made to effect this desirable object,
but such appliances have hitherto failed, by being in the way of the weaver in taking
up broken ends, and in putting in and taking out of the box the shuttle, and further that
such appliances projecting over the yarn a distance from the reed, and, travelling

page_text: backwards and forwards with the same will necessarily be carried at each stroke of the
slev over the woven fabric, and should the weaver for the time being attempt to pick
off broken warp threads from the fell of the cloth, he would most certainly be struck
by the projecting or protruding appliances.
These serious objections counterbalance any advantage that would otherwise be
derived from the application of such devices; the weaver preferring to run the risk of
being struck by the shuttle flying, which is most serious and dangerous, rather than
submit to the inconveniences such appliances usually entail.
To obviate these serious objections, and at the same time prevent the shuttle flying,
is the object of the present invention.
My invention consists in placing a rod or bar behind the reed, and so arranged in
position, as to traverse to and fro with the reed, and follow in close proximity above
the warp or the varying angle of the shed of such warp, that the warp threads in front
of the reed may offer the greatest possible resistance to the shuttle rising, flying out,
or leaving the sley.
In the accompanying drawings,
Fig. 1 is an end elevation, Fig. 2 a side view, and Fig. 3 a plan of a power loom
constructed in accordance with the said invention.
A is the loom framing, B the sley-sword, C the reed. The parts enumerated are
old and well understood and form no part of my invention.
My invention consists in the application of a rod or bar D, behind the reed C),
and which may be connected at each end to the vertical spring blades E E, fixed at
their lower extremity to the adjustable brackets FF. To prevent the rod or bar
from bearing unduly upon the face of the reed, it may be relieved by the slide-pieces D¹,
which are secured to the bar by set screw D2, and slide upon. the face of the sley-
sword.
With the backward movement of the sley, the blades, to which the bar D is
attached, are raised into a more upright position by being pushed back by the sley,
causing the bar to follow the incline of the top part of the shed.
The rising and falling movement of the said bar is regulated by moving the
brackets E E backwards or forwards in the slots G to increase or diminish the
distance between the axis of the sley-sword and the point of attachment of the spring
blades to the adjustable brackets F F.
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 :-
The employment of a rod or bar acting behind the reed, substantially as described
and illustrated for the purpose set forth.
