COMPLETE SPECIFICATION.
Improvements in Loom Shuttle Guards.
We, WILLIAM EDWIN BRIGGS PRIESTLEY, of Albion Mills, Laisterdyke,
Bradford in the County of York, Manufacturer, and WILLIAM DEIGHTON of the
same place, Mechanic, 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 certain improvements in loom shuttle guards, and has
for its object, the construction of same in such a manner that, the guard is auto-
matically placed in such a position on starting the looms, that it is impossible for
the shuttle to leave the loom should it become diverted in its course across the "race"
thereby preventing personal injury to the attendant or other persons in close
proximity to the loom, and further, that the "reed" space, course of the shuttle,
"shed "of the warp and cloth are all clear for examination during the process of
weaving.
In order that our invention may be fully understood, we will describe the same
in detail by making reference to the accompanying sheet of drawings in which
Fig. 1 represents an elevation of the lathe of a loom constructed in the ordinary
manner, with our improved shuttle guard attached.

details.
To the hand rail A we secure the brackets B. supporting a shaft C. to which are
secured the arms F. F. and G. carrying light guard bars or wires H. H. extending
the full width of the reed space C₁ thereby forming a guard above and in front of
the shuttle "race" between the shuttle boxes J. J.
To one end of shaft C. is connected the spiral spring R or the like, the opposite
end of which is by preference connected to the hand rail A. The centre bracket B.
is formed with an inclined face B' against which slides a projection G³ on arm G
when the guard is in the act of falling to the position shown in Fig. 1 for guarding
the shuttle, upon the projection G' arriving at the point L. it is clear of the inclined
face B', and by the contraction of the spring R. the shaft C is moved in the direction.
of the arrow, whereupon the before mentioned arms and guard bars H. H. are drawn
such a distance that the projection G' on arm G engages with a notch formed on.
the underside of centre bracket B.
On stopping the loom the projection Gon arm G may be disengaged from the
bracket B. by moving the shaft C. in the opposite direction to that indicated by
the before mentioned arrow, thus liberating the guard, that it may be raised to the
position shown by dotted lines in Fig. 2 by which free access is given to the reed.
cloth and warp threads.
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 :-
In a shuttle guard an arm G. having a projection thereon, combined with a
bracket B. provided with an inclined face B' all arranged substantially in the-
manner as shown and described.
