Improvements in Shuttle Guards of Looms for Weaving.
I, RALPH WADDINGTON, of 4 Lancaster Street, Blackburn, in the County of
Lancaster, Weaver, do hereby declare the nature of this invention to be as
follows:
-
This invention relates to improvements in shuttle guards of looms for weaving,
the object being to construct a guard which can readily be applied to existing
looms, and one which is efficient in its action and can be manufactured and applied
at a very small cost. The invention consists of a guard made of stout wire
operated and controlled by simple connections from the ordinary stop handle,
in such a manner that when the loom is started, the guard automatically assumes
the active or on" position, and as soon as the loom is "knocked off" the guard
is folded close to the reed cap and out of the weavers way.
According to this invention I employ a guard made of stout wire hinged to the
front of the reed cap. One end of the guard is bent and carried to the top of
the reed cap, and to this end is attached a spring which maintains the guard in
I
its active or on
"position.
Beneath or attached to the end of the guard is a rod or lever mounted on a
fulcrum stud, and a tail on one end of such rod or lever extends to below the
shuttle box. On the stop handle is a stud which rests in contact with the tail of
the lever, and when the loom is at rest the stud pressing on the tail causes the
opposite end of the rod to lift the end of the guard and to fold the latter on its
When
hinges so that it lies close to the reed cap and out of the way of the weaver.
the handle is moved to start the loom the pressure of the stud is taken off the tail
and the spring draws down the end of the guard and raises the latter to its active
position, where it remains until the loom is "knocked off."
The stud on the stop handle may be connected directly to the guard in some
cases.

in and by the following statement:-

According to this invention I employ a guard made of stout wire hinged to
the front of the reed cap. One end of the guard is bent and carried to the top
of the reed cap and to this end is attached a spring which maintains the guard
in its active or on position.

Beneath or attached to the end of the guard is a rod or lever mounted on one
or more bearings and a tail on one end of such rod or lever, extends to below the
shuttle box. On the stop handle is a stud which rests in contact with the tail
of the lever and when the loom is at rest the stud pressing on the tail causes
the opposite end of the rod to lift the end of the guard and to fold the latter on
its hinges so that it lies close to the reed cap and out of the way of the weaver.
When the handle is moved to start the loom the pressure of the stud is taken off
the tail and the spring draws down the end of the guard and raises the latter to
its active position where it remains until the loom is "knocked off."
The stud on the stop handle may be connected directly to the guard in some
cases.
The accompanying drawings are in illustration of my invention.
Fig. I shews a longitudinal elevation & Fig. II an end elevation of the shuttle
guard, where the guard is shewn closed and out of the way of the weaver, whilst
Fig. III shews an enlarged end elevation with the guard open as when the loom
is working.
B. B. B are three bearings attached to the reed cap N, and carry the
guard A. A. A. and allow it to swivel, one end is bent over the top of the reed cap,
and connected with the lever D on the under side of the shuttle box K, by the
rod C. This rod C is made in two pieces with a slot to allow for adjustment
for different widths of reeds. The lever D is bent to clear any obstruction which
may be in the way of its working, and is carried by the two bearings EE which
allows a rotary motion of the lever D. The lever D terminates in a tail F. At L
is shewn a spring having one end attached to the vibrating rod M, which carries
the shuttle box of the loom, and the other end to the lever D on the opposite end
of the bearings EE from the tail F. H is the stop handle of the loom, and to
it is attached a stud G. This stud G is arranged so that it just touches the tail F
when the loom is in motion.
The action is as follows:-
The loom is started by moving the stop handle H from left to right.
The loom is started by moving the stop handle H from left to right, this liberates
the tail F from the stud G, consequently the spring L operates and pulls down
the other end of the lever D and along with lever D the rod C and lifts the guard
open, where it remains until the loom is stopped, when the opposite happens and
the guard closes out of the way of the weaver.

tion, and in what manner the same is to be performed, I declare that what I
