PROVISIONAL SPECIFICATION.
Improvements in Shuttle Guards for Looms.
We, HERBERT RHODES of The Woodlands, Staleybridge, in the County of
Chester, Gentleman, and GEORGE THORNLEY of Hadfield Road, Hadfield, in the
County of Derby, Mill Manager, do hereby declare the nature of this invention to
he as follows:-
The objects of this invention, which relates to shuttle guards for looms, are, the
production of an efficient guard at a very low cost, to ensure the guard.coming into
action automatically when the loom is started, to enable it to be put out of action
easily, and to provide that it shall be completely out of the weaver's way when she
is unweaving or changing shuttles.
A shuttle guard constructed according to this invention.consists merely of a length
of wire parallel with the lathe top of the loom and hinged or pivoted thereto at each
end, and, if desired, in the middle. In practice each end of the wire may be bent
three times at right angles, and it is pivoted or hinged to the lathe top by means
of loops.or staples embracing the parts between the second and third bends. The
free ends of the wire may be cranked ar bent so as to come over the lathe top,
thus acting as a stop, and one or both of them is or are provided with a fixed or
adjustable balance weight. The middle of the wire may be cranked and hinged to
the lathe top in dike manner and in line with the end hinges. When the loom is at
work the weight or weights rest upon the lathe top, and the wire guard is extended
outwards from the lathe top. To put the guard out of action, it is pushed against
the reed top, when the weighted end or ends of the wire will be. brought vertical.
The guard will remain in this position so long as the loom is stopped, but on the
instant of starting, the vibration of the lathe will cause the weight to fall, bringing
the guard into action.
The construction described is typical only and may be considerably varied,
particularly in respect of the method of connection with the lathe, and the connection
of the weight or weights with the guard.

Improvements in Shuttle Guards for Looms.
We, HERBERT RHODES of The Woodlands, Staleybridge in the County of
Chester, Gentleman, and GEORGE THORNLEY of Hadfield Road, Hadfield, in the
County of Derby, 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 invention relates to shuttle guards for looms and its objects are to produce
an efficient guard at a low cost, to ensure the guard coming automatically into
action when the loom is started, to enable it to be put out of action easily, and to

page_text: provide that it shall be completely out of the weaver's way when she is unweaving
or changing shuttles.
A shuttle guard constructed according to this invention consists of a length of
wire hinged or pivoted upon and parallel with the lathe top or hand rail. The
ends of the wire are suitably cranked or bent and are furnished with staples loops
or the like by means of which they are attached to the rail. The free ends of the
wire may be cranked or bent so as to come over the lathe top and act as stops to
limit the movement of the shuttle guard, and one or both of them is or are provided
with a fixed or adjustable balance weight. The wire may also be cranked or bent in
the middle or other suitable part or parts of its length and hinged to the lathe top in a
like manner and in line with the end hinges. When the loom is at work the weight or
weights is or are in their lowest position and rest upon the lathe top, and the wire
guard extends outwards. To put the guard out of action it is pushed against the
reed top, when the weighted end or ends of the wire will be raised to a vertical
position. The guard will remain in this position so long as the loom is stopped,
but on the instant of starting the vibration of the lathe will cause the weight to
fall thus moving the guard outwards and bringing it into action.
In order that our invention may be more readily understood we have hereto
appended a sheet of drawings reference to which we make hereinafter.
Figures 1 and 2 illustrate respectively in front and end elevation the position of
the guard when out of action and when the loom is stopped.
Figures 3 and 4 illustrate similarly in front and end elevation the position of the
guard when in action and when the loom is running.
The guard consists of a length of wire or the like A suitably bent or cranked at
its end and preferably also in its middle. This wire is hinged to the lathe top or
hand rail B by means of the staples or loops C within which it is capable of
rotating. One end of the wire is extended or is furnished with an arm D carrying
a counter weight E which is preferably adjustably attached. In the position shewn
by Figures 1 and 2 the arm and counterweight have been raised until they are past
the point of balance but further rotation or movement of the guard is prevented by
the cranked parts of the wire coming against the hand rail. If desired special
stops may be provided for limiting the movement in either direction. The position
of the guard is such that very little movement or vibration is required to be
communicated to the lathe to cause the counterweight to fall forward and bring
the guard into the operative position shewn in Figures 3 and 4.
This necessary
vibration is established when the loom is started and the lathe moves. The guard
then automatically assumes its safety position the extension of the wire falling
upon the rail and ensuring a correct position being maintained.
It is preferred to form one of the staples or loops C, preferably the middle one,
of a different size or shape to the others so that by tightening or loosening this
loop upon the rail it may be caused to grip or release the wire. A tension device
is thus established by means of which the ease with which the wire guard turns or
rotates may be easily regulated.
The construction described is typical only and may be considerably varied,
particularly in respect of the method of connection with the lathe and the connection
of the weight or weights with the guard.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
A shuttle guard constructed arranged and operated substantially as hereinbefore
described and as illustrated by the accompanying drawings.
