PROVISIONAL SPECIFICATION.
Improvements in Shuttle Guards for Weaving Looms.
I, FREDERICK SUCKSMITH WALKER, of Collins Street, Great Horton, near
Bradford, in the County of York, Overlooker, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in shuttle guards and its object is to
provide a cheap and efficient guard adapted to be readily pushed under the hand-
rail out of the way and to automatically return to its working position when the
loom is started.
For this purpose I employ a bar or rod of any suitable section having an arm at
each end pivoted in adjustable brackets or bearings secured to the hand-rail of the
loom. One or more intermediate arms may also be employed. The pivot of one
of said arms is extended or one of the said arms is otherwise adapted to carry an
adjustable cam or its equivalent having a notch depression or the like in its edge or
face and a spring catch is adapted to bear on said cam. This adjustable cam is so
arranged that when the guard is in its proper working position the spring catch
engages the said notch or depression in the cam and prevents the guard being forced
outwards out of position but the parts are so formed and arranged that the guard
may, when the loom is stopped, be readily pushed inward against the hand-rail out
of the way.
The spring catch may be in the form of a simple spring or it may consist of a
bolt pressed towards the cam by a spiral or other spring.
Instead of only one cam and spring two or more of the arms may be fitted with
cams and springs provided to engage them.

COMPLETE SPECIFICATION.
Improvements in Shuttle Guards for Weaving Looms.
I, FREDERICK SUCKSMITH WALKER, of 3 Collins Street, Great Horton,
Bradford, in the County of York, Overlooker, do hereby declare the nature of
this invention and in what manner the same to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention has reference to an improved arrangement of shuttle guard.
It is so constructed so that the weaver can easily put the shuttle guard out of
action when required for piecing up weft or broken warp, but immediately the loom
is set on, the throw of the " going-part" will reinstate the shuttle guard self-
actingly, or put it into position for acting.
In order that my invention may be better understood I will make reference to
the accompanying sheet of drawings, wherein
Fig. 1 is a section of the hand rail of a loom to which my improved device is
attached.

page_text: This drawing shews the parts in action, and when in the position shewn
would prevent a shuttle flying from the slay board.
Fig. 2 shews the shuttle guard as being pushed near the reed, and the dotted lines
shew the shuttle guard at its highest position when not required to be in use.
Ai
a bracket attached to the hand rail B, and mounted in the said bracket is a cam or
eccentric C capable of being partially revolved on its fulcrum D. To the axis of
the said cam, is an arm E secured by bolt F to the bar or shuttle guard G. The
shuttle guard is kept rigid in any of the three positions shewn in the drawings, by
means of the foot H on rod I, which foot is forced upon the eccentric by spiral
spring J, the said rod I being supported in its vertical position by a bracket or
yoke Lattached to the first named bracket A. The cam C can be fixed or adjusted
upon the fulcrum D by means of set screw M. This adjustment of the cam permits
the latter to alter the position of the shuttle guard to be adapted for large or small
.shuttles.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be perfornied, I declare that what I
claim is
A shuttle guard, having combined with it arms E, cam or eccentric C, vertical
rod I, and spiral spring J, all used in combination and operating in the manner
described and shewn in the drawings.
