It will be observed that whenever the loom stops
working, whether it is stopped by hand or automatically, the hand lever
has to be moved, and this movement is communicated to the shuttle guard
by the mechanism just described, placing the guard rod beneath the hand
rail, and leaving the whole of the shuttle race free and unencumbered.
The act of starting the loom brings the guard again to the working
position without any extra act having to be performed by the weaver. The
action is entirely automatic, and the weaver has not anything to do that
she has not to do with the present unguarded looms. The arrangement
appeared to ourselves to be a very efficient one, and it has the merit
that the length of the guard can be made greater than the width of the
cloth, a further advantage that will be recognized by practical weavers.

RULER AND TRIANGLE FOR HATCHING.
The instrument shown in the cut is the invention of Mr. Maginnis, and is
designed for producing equidistant hatchings. It consists of a short
ruler, A, and a triangle, B, supposed to be one of 45 deg., but which may be
of any angle. The triangle carries two stops, c c, while the ruler is
provided with a conical piece, D, which is slotted, and is held by a
screw.
