PROVISIONAL SPECIFICATION.
A New or Improved Automatic Loom Shuttle Guard.
We, LAZARUS CROMPTON, of 110, Halliwell Street, Salford, Overlooker, and
WILLIAM TURNER, of 36, Howard Street, Salford, Weaving Manager, both in the
County of Lancaster, do hereby declare the nature of our said invention to be as
follows:-
This invention relates to a new or improved automatic loom shuttle guard and is
designed to protect weavers from injury in case shuttles fly out of the loom. The
shuttle guard is composed of a metallic rod mounted in suitable bearings disposed
on the lathe above the reed. On one end of the metallic-rod is fixed a lever with a
pivot to which is attached a spiral spring, india-rubber or elastic band, the other
end of the latter being attached to the lathe. The metallic rod is mounted in
suitable metallic bearings secured in any convenient manner to the lathe of the
loom. To prevent the metallic rod swagging, springing or bending one or more
intermediate bearings are provided which are attached to the lathe in any con-
venient manner. When the shuttle guard is in position to prevent the shuttle
flying out the metallic rod is above the centre line of the spiral spring, india-
rubber or elastic band and by which the same is kept in position. The metallic
rod is provided with stops or arms to determine the action of the same and ensure
of the correct position of the shuttle guard or metallic rod before mentioned. When
it is desired or necessary to handle the shuttle all that the weaver has to do is to
press the metallic rod towards or under the reed or lathe, which action places the
bent end or its equivalent before mentioned below the centre line of the spiral
spring or india-rubber or elastic band, thus holding the same out of the way.
Immediately the loom starts the force of the backward stroke of the lathe over-
comes the power of the spiral spring or india-rubber or elastic band and auto-
matically re-sets the shuttle guard.

DESCRIPTION OF DRAWINGS.
Fig. 1 is a longitudinal elevation of our new or improved automatic loom shuttle
guard applied to the lathe of a loom-Fig. 2 a longitudinal elevation of our new
or improved automatic loom shuttle guard provided with a middle bearing or
support when applied to.what are known as "wide" looms Fig. 3 an enlarged
part elevation of Fig. 1-Fig. 4 an end view of Fig. 3 showing guard in position
over the shuttle race-Fig. 5 an end view of Fig. 3 and the opposite end to that
shown in Fig. 4-Fig. 6 an end view showing the guard pushed back against or
under the lathe of the loom to allow of the shuttle being readily handled by the
weaver" or attendant, and Fig. 7 an end view of Fig. 3 showing the position
of the "stop" when the shuttle guard is pushed back as in Fig. 6.
In all the figures the same letters are employed to indicate corresponding parts.
A represents so much of the lathe of a loom as is necessary to illustrate our said
invention; B the metallic rod comprising our new or improved automatic loom
shuttle guard; C bearings or supports; Ď operating lever; E stop lever, and G
india-rubber or elastic band.

"
The shuttle guard is composed of the metallic rod B mounted in the bearings
or supports C cast to or formed with the flanges H by which the same are secured
to the lathe A of the loom by the screws I or their equivalents; the said bearings
being disposed or mounted on the same above the "reed." On one end of the
metallic rod B is fixed the operating lever D by the set screw K. The operating
lever D is provided at its outer end with the pivot or centre L to which is attached
the india-rubber or elastic band G; the other end of the latter being attached
to the pivot or centre M cast to the flange H secured to the lathe A of the loom.
In case our invention is applied to what are known as wide looms the metallic
rod B is bent in the middle or thereabouts of its length, the same being supported
by the intermediate bearing O as shown in Fig. 2, to prevent the same "swagging,"
springing, or bending; the bearing O being attached to the lathe A by the screws l'
or their equivalents in any convenient manner. The metallic rod B is provided
with the stop lever E secured thereon by the set screw R or its equivalent to deter-
mine the action of the same in combination with the stops X and ensure of the
correct position of the shuttle guard or metallic rod B before mentioned. When
it is desired or necessary to handle the shuttle all that the weaver' or attendant
has to do is to press or push the metallic rod B towards or under the reed or the
lathe A of the loom as shown in Figs. 6 and 7, which action places the centre L
of the lever D before mentioned below the centre line YZ, thus holding the metallic
rod B forming the shuttle guard out of the way. Immediately the loom starts-
that is, set in motion-the force of the backward stroke of the lathe A of the loom
overcomes the power of the india-rubber or elastic band G and automatically re-sets
the rod B forming the shuttle guard. If desired a spiral spring may be employed

page_text: in lieu of the elastic band G. To determine the correct position of the rod B the
bearings C are provided on one side with the projecting stops X against which the
said rod B is arrested and held over the shuttle race by the india-rubber or elastic
band G.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is;-
The general arrangement, construction, and combination of parts composing the
new or improved automatic loom shuttle guard, consisting of the rod B mounted
in the bearings or supports C provided with the stops X on the flange H; the rod B
being provided with the operating lever D, stop lever E, and the india-rubber or
elastic band G or its equivalent, the whole being applied and operating substantially
as described and as illustrated in the annexed drawings.
