PROVISIONAL SPECIFICATION.
Improvements in Shuttle Guards for Looms.
We GEORGE SHEPHERD, of Holmes Mills, Bacup in the County of Lancaster Cotton
Spinner and Manufacturer, and GEORGE HENRY PILLING, of the same place, Mechanic,
do hereby declare the nature of the said invention to be as follows:-
The object of our invention is to prevent the shuttle when passing across the shed
flying out and doing damage as is frequently the case, and our invention consists in
applying brackets forming hinges to the hand bar in front of the reed to which
brackets a bar is hinged which in the lengthway is parallel to the face of the reed and
extends across the loom above the upper warp threads of the shed and over the shuttle
race so as to keep down the shuttle in the race should it tend to rise when picked
across the shed.
This bar being hinged can be readily turned up out of the way when required and
when so turned up, and left to itself it will assume the turned down and guarding
position the moment the loom begins to work.

COMPLETE SPECIFICATION.
Improvements in Shuttle Guards for Looms.
We, GEORGE SHEPHERD, of Holmes Mills, Bacup, in the County of Lancaster,
Cotton Spinner and Manufacturer, and GEORGE HENRY PILLING, 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 :-
The object of our invention is to prevent the shuttle when passing across the shed
from flying out and doing damage as is frequently the case, and our invention consists
in applying brackets forming hinges to the hand bar, rail or tree in front of the reed
to which brackets a metal bar is hinged which in the lengthway is parallel to the face
of the reed and extends across the loom above the upper warp threads of the shed and
over the shuttle race so as to keep down the shuttle in the race should it tend to rise
when picked across the shed.
This metal bar being hinged can be readily turned up out of the way when required,
and when so turned up, and left to itself it will assume the turned down and guarding
position the moment the loom begins to work.
Fig. 1 is a cross section showing the lathe, reed and hand rail of a loom with our
improved shuttle guard attached, fig. 2 is a front view, and fig. 3. a plan view of part
of the same.
a, is the lathe; b, the hand bar rail or tree; c, the reed; d, in fig. 1 the lines of
the warp thread when the shed is open.
e, is one of two brackets secured to the front of the hand bar, rail or free, b, one
bracket being attached near each end.
To each bracket a part e', is hinged to turn on the joint pin e², and to these parts e¹,
a flat metal bar e³, is rivetted.
This metal bar e³, extends the whole width of the reed space, and its end is clear
of the weft fork, and may be made if desired with the ledge e*, shown in dotted line
in fig. 1.
The brackets e¹, project downwards at e', so as to come against the edge of the metal
bar e³, and prevent it from turning further down in that direction.

page_text: There is also a flat spring f, on each bracket secured to it by a screw f1, the free
end of this spring acts upon a projection from the joint part el, as shown best in fig. 1,
to cause it to be held with some pressure in the position in which it is shown in full
line in fig. 1, but it can be turned up when required so as to be out of the way, into
the position shown in dotted line in fig. 1, when the flat spring f, will be opposite
the round part of the joint of the pari el, in which position the flat spring does not
exert pressure to prevent the bar e³, from turning froin its position shown in dotted
line in fig. 1 to the horizontal position shown in full line the moment the loom begins
to work which ever way the lathe a, first begins to move whether forward or
backward.
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.
1. The combination of a bar hinged to the hand bar, rail or tree of looms, so that
it can be placed in two positions, in one of which it is out of the way and in the other
it acts as a guard to prevent the shuttle from leaving its race, or flying out, to lo
damage, the hinged bar when turned up out of the way automatically assuming the
guarding position when the loom starts to work substantially as herein before described
and illustrated by the drawings.
2. The combination of the hinged bar (e³) with its joint brackets and the hand bar,
rail or tree (b) and the spring or springs (f) acting substantially as and for the
purpose herein before described and illustrated by the drawings.
