IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR ACTUATING SHUTTLE GUARDS
Year: 1885

page_text: I FRED WATERHOUSE of the firm of Jonas Waterhouse and Sons, Globe Mills,
Bradford in the County of York, Manufacturer, do hereby declare the nature of
my invention for "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR
ACTUATING SHUTTLE GUARDS," and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
The object of my invention is to mount and actuate shuttle guards in such a
manner, that when the loom is set to work the shuttle guard is moved automatically
into such a position that should the shuttle leave its direct course it is prevented
flying upwards; and when the loom is stopped the guard is moved into a position
that the weaver has a full view of the fabric and free access to the reed.
The invention consists of connecting the ordinary starting and stopping rod with
a quadrant in connection with a bar and levers, by which on the loom being
started a guide bar is made to advance from the top rail and cover the race of the
shuttle.
In the accompanying drawings Fig 1. represents the end view of a loom with my
improvement added thereto, Fig 2 is a plan shewing the attachment of the starting
rod to the apparatus Fig 3 is a cross section through the lathe or going part and
Fig 4 is a view of the apparatus that is fixed to the underside of the lathe; in all
the figures similar letters indicate like parts where they appear.
In the ordinary stop and starting rod A. I bore a hole through which I pass the
rod B carried at the other end by the stud C jointed to this rod by links D is
quadrant E hinged at the bottom to the bracket E¹. The top portion of the
quadrant plate E is placed between two small pullies F. F. mounted on studs that
are secured to the bar G which is held in position by the straps H secured to the
underside of lathe J.
To the bar G I secure pins G' that pass through slots formed in the respective
arms of the bell crank levers K and to the other arms of the said levers, I joint the
bars L which are also connected to the levers M. M. mounted in suitable brackets N
that are attached to the lathe J. To the upper arm of each of these levers, I secure
rods P that pass through the hand rail R of the going part, and which are bent
downwards at the front somewhat in the manner as shewn, and finally secured to
the guide bar S that extends across the loom from one shuttle box to the other,
thereby covering or guarding the shuttle in its travel from one side of the loom to
the other.

page_text: The drawings shew the guide bar S in the position it will be when the loom is
working; and when the loom is stopped the rod A moving as usual in the direction
of the arrow will cause the hinged quadrant E and the bar G to move in the same
direction by which the levers K and L are actuated, and the rods P and guide bar S
moved towards the hand rail R thus exposing the fabric to the full view of the
weaver, and giving free access to the reed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The combination of the apparatus for actuating shuttle guards arranged substan-
tially in the manner as hereinbefore described and illustrated by the accompanying
drawings.
The combination of the bar B with the quadrant plate E and bar G in the manner
and for the purpose described.
The combination of the rods P with the guide bar S for the purpose described.
The guide bar S moving in a horizontal direction for the purpose described.
