We, JOHN COCKING FIELDEN of 7. Meal Street Manchester in the County of
Lancaster Manufacturer and WILLIAM SLATER of Culcheth near Warrington in the
County of Lancaster, Mill Manager, do hereby declare the nature of this invention to
be as follows:-
This Invention relates to shuttle guards and it has for its object to operate or
actuate the shuttle guard by simple and effective means and in such a manner that the
shuttle guard is folded or turned out of the way when the loom is at rest and is.
opened or moved outward or into the protective position when the loom is at work..
The shuttle guard may be a rod, grid, parallel bars, net work or of other ordinary
or suitable construction but it must be pivotted or hinged to the front of the handrail
The arm is
and at the end nearer to the knocking off motion it has a projecting arm.
connected by rods links or levers to a slotted bent or curved lever which is actuated
by the knocking off notion through the agency of a stud or pin on the knocking off
rod engaging in the slot of the slotted lever. The motion of the knocking off rod is
communicated through the slotted lever, the connecting rods, links, or levers and the
arm to the shuttle guard in such a manner that the shuttle guard is folded out of the
way when the loom is stopped and opened out or put into the protective position when
the loom is started.
One of the connecting rods or links is constructed so that its effective length may
be increased or diminished by a nut and screw or other device so as to provide for
adjustment.

page_text: Improvements in and Connected with Shuttle Guards for Looms.
We JOHN COCKING FIELDEN of 7. Meal Street Manchester in the County of
Lancaster Manufacturer, and WILLIAM SLATER of Culcheth near Warrington in the
County of Lancaster 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 Iuvention relates to shuttle guards for looms and it has for its object to secure
the automatic operation of the guard by simple and effective means in such a manner
that it is folded or turned out of the way when the loom is at rest and is opened or
moved outward into the protective position when the loom is at work.
The appended sheet of drawings illustrate in what manner our Improvements may
be carried into practical effect. In each of the figures similar details are indicated by,
similar letters of reference.

Fig. 1 is a front view and Fig. 2 is a side view of a portion of a loom provided
with a shuttle guard and having our Improvements applied thereto.
· The shuttle guard A may be a rod, grid, parallel bars, net work or other suitable
and convenient device and is pivotted or hinged to the hand rail B. In the drawings
the pivot or hinge is shown at C. At the end of the guard which is nearer to the
knocking off lever D there is a projection, cranked arm, or bent lever E, attached to
the guard and this part is connected by suitable rods or links such as F to a slotted
bent or curved lever G. A pin or stud H is secured to the knocking off lever in such
a position that it will engage within the slot of the lever G. The slot is curved as
indicated in the drawings Fig. 1 so that the motion of the knocking off lever will
communicate a vertical motion to the lever G. When the loom is at work the
kocking off lever, the curved lever G, the connecting rods and the shuttle guard
occupy the positions indicated in full black lines and the shuttle guard is in its
protective position. When the loom is at rest the knocking off lever and the shuttle
guard together with the parts of the apparatus connecting them, occupy the positions
indicated in dotted lines and the shuttle guard is folded under the sley cap out of
the way and thus does not interfere with piecing or other manipulation of the
operative.
One of the connecting rods, or in case a continuous connecting rod is. used, one end
of the rod is provided with a screw' and nut or other device as at I, in order that
its length may be adjusted.
In the drawings we have represented the connecting rod as passing downwards and
then upwards through the slot in the sley sword to the back of the sley cap where it
is connected to the projection from the shuttle guard; we have also shown the
connecting rod as forming a complete loop K at its lowest part and in ordinary cases
we prefer so to construct and arrange it, but we do not limit ourselves to such
construction and arrangement.

page_text: It is obvious that instead of using the slotted lever G we may employ a lever having
a curved end corresponding and equivalent to the curved slot, in which case the
curved end or part may engage or work between two pins studs or their equivalent on
the knocking off lever.
We are aware that folding shuttle guards have for some time been employed, and
that they have been operated from and by the knocking off lever; but the devices
employed hitherto for operating the guard have, as far as we have been able to
ascertain, been more complicated than those hereinbefore described and less certain in
their action.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. As a means for operating a shuttle guard; the combination and arrangement of
a pin or stud attached to the knocking off lever, a slotted lever, connecting rod or
rods, and an arm or projection from the shuttle guard; substantially as herein before
described and as illustrated by the accompanying drawings.
2. In apparatus for communicating motion from the knocking off lever of a loom
to a folding shuttle guard, a lever engaging with a pin stud or equivalent device on
the knocking off lever; substantially as hereinbefore described and as illustrated by
the appended drawings.
