PROVISIONAL SPECIFICATION.
A New or Improved Automatic Loom Shuttle Guard.
We, LAZARUS CROMPTON of 30 Grosvenor Street, Moses Gate, Overlooker,
and WILLIAM TURNER of 30 Bolton Road, Farnworth, 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.
This shuttle guard is composed of a metallic beut rod or its equivalent mounted
in suitable bearings disposed on the front side of the lathe above the reed. One
end of the metallic rod is bent in the form of a lever provided with an annular
groove or recess to which is attached a spiral spring mounted in a slot or opening
in the lathe of the loom. The said bent end may be substituted by a lever if
desired, the same being secured thereto in any convenient manner. When the
shuttle guard is in position to prevent the shuttle flying out, the bent end or its
equivalent is above the centre line of the spiral spring, and by which the same is
kept in position. The metallic rod is provided with stops to determine the action
of the same and ensure of the correct position of the shuttle guard. When it is
desired or necessary to handle the shuttle all that the weaver has to do is to press
the metallic rod towards the reed, which action places the bent end or its equivalent
before mentioned below the centre line of the spiral spring, thus holding the same
out of the way. Iminediately the loom starts the force of the backward stroke of
the lathe overcomes the power of the spiral spring and automatically re-sets the
shuttle guard.

DESCRIPTION OF DRAWINGS.
Fig. 1 is a part front elevation of the lathe of a loom with our new or improved
shuttle guard applied.
Fig. 2 is a sectional side elevation showing shuttle.guard in position to 'prevent
shuttle flying out when passing through the "shed."
Fig. 3 is a sectional side elevation showing shuttle guard moved out of the way
when necessary to handle the shuttle.
Fig. 4 is a sectional side elevation showing position of spring when shuttle guard
is in the position shown in Figs. 1 and 2, and Fig. 5 when in position shown in
Fig. 3.
A is the lathe; B the reed, and C the shuttle. The shuttle guard is composed
of the metallic bent rod D mounted in the bearings E secured by the screws G to
the front side of the lathe A above the reed B. One end of the metallic rod D
is bent to form the lever H provided with the annular groove or recess I to which
is attached the spiral spring K mounted in the slot or opening L in the lathe.A.
The metallic rod D is provided with the bent ends or stops M to determine the
action of the same and ensure of the correct position of the shuttle guard as
shown in Figs. 1 and 2. The bent ends or stops M bear against the side of the
lathe when the shuttle guard or metallic rod D is in position to prevent the shuttle
flying out as in Fig. 2. When the shuttle guard or metallic rod D is in position
to prevent the shuttle flying out the top end of the lever H, to which the spring K
is attached, is above the horizontal centre line of the fulcrum N of the said spring
as shown in Figs. 1 and 4, by which the shuttle guard or metallic rod D is held
in its true working position. When it is desired or necessary to handle the
shuttle C the shuttle guard or metallic rod D is moved out of the way by pushing
the same towards the reed B as in Fig. 3, which action places the top end of the
lever H below the horizontal centre line of the fulcruin N as in Fig. 5, which
position holds the same out of the way of the weaver. Immediately the loom
commences its operations the force of the backward stroke of the lathe A overcomes
the power of the spring K and automatically re-sets the shuttle guard or metallic
rod D to the position shown in Figs. 1 and 2.
Having now particularly described and ascertained the nature of our said inven-
tiou, 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, applied and operating as herein-
before described and as illustrated in the annexed drawings.
