JOHN MONK of Peel Hall Foundry, Ironfounder, JAMES LANG of Langs Yard, Park
Road, Overlooker and JOHN CATTERALL of 85 New Hall Lane, Overlooker, all of Preston
in the County of Lancaster do hereby declare the nature of this invention to be as
follows:-
A cranked or bent lever of wood, metal or other material is attached at one end to
the framing of the loom, it then passes under the slay, and one part stands upwards
at the back of the slay, the other end of cranked lever is attached to one end of the
rod which constitutes the shuttle guard, the guard is composed of wood, metal or
other inaterial and can be made of round, square, angle or any other section the ends
being round and working in bearings at both ends of the slay cap, owing to one end
of cranked lever being attached to framing of loom as before described, and the other
end to end of guard it will be seen that the backward and forward movement of slay
opens and closes the guard at each revolution of the crank shaft, the guard
being open when the shuttle is passing through the warp and closed when the slay is
beating up the weft, the cranked lever as before described works free on its axis or
bearings at both ends.

Improvements in Shuttle Guards employed in Looms for Weaving.
We, Jonx MONK, of Peel Hall Foundry, Ironfounder, JAMES LANG, of Lang's Yard,
Park Road, Overlooker, and JouN CATTERALL, of 85 New Hall Lane, Overlooker, all of
Preston, in the County of Lancashire, 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:-
Our invention relates to the construction and arrangement of a shuttle guard for a
loom, such that it is automatically moved by the movement of the slay, being open
or away from the slay cap while the shuttle is passing through the warp, and being
brought close to the slay cap while the slay is beating up the weft.
Figure 1 of the accompanying drawings is an end view of the slay in its position
while the shuttle is passing through the warp its front position after the shuttle bas
passed through being shewn in dotted lines.
Fig. 2 is a nart front view.

page_text: On the slay cap S we pivot at both ends a bent rod G constituting the shuttle
guard. One end of the rod is bent to form a crank C to which is jointed one
end of a bent link L the other end of which is pivotted at P to the framing of
the loom. The angle of the crank C and the position of the pivot P are such
that when the shuttle is passing through the warp, the guard rod G stands in
front of the slay cap so as to prevent the shuttle from flying upwards if it should
escape. But when the shuttle has passed the guard rod G is close against the
slay cap as indicated by the dotted lines.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what we
claim is:
A shuttle guard for a loom having at its end a crank arm linked to a fixed
pivot, substantially as and for the purpose set forth.
