Improvements in the Shuttle Guards of Looms.
WC, GEORGE EDWARD HAMBLET, of Bury, in the County of Lancaster,
Engineer, and HARRY CLIFTON, of Bury, aforesaid, Chemist's Assistant, 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 is designed to provide a simple and efficient shuttle guard for
looms which can be easily lifted to piece or examine the work but which the move-
ment of the loom when working will cause to return to and maintain it in normal
position.
It consists essentially of a pivoted or movable shuttle guard attached to the
slay or lathe top provided with a spring catch or clutch at one or both ends.
It will be fully described with reference to the annexed drawings in which the
shuttle guard is attached to the lathe top or slay.

The guard A is constructed in the form of a cage with longitudinal wires or
rods a and transverse brackets a' by which the wires a are supported.
The back wire a passes out through the end brackets a and is pivoted in
brackets B and C affixed to the slay or lathe top D. The bracket B is provided
with a spring barrel or chamber to receive a spiral or coiled spring one end of
which is attached to the bracket and the other to the rod a. The face of the
bracket B is formed with a single curved or inclined notch b and to the wire a is
attached a clutch E with a corresponding projection e which engages with the
notch b and serves to hold the guard A in normal position when at work.
The spring is fixed so as to tend to hold the projection of the clutch E against
the notch b and also against the face of the bracket B, and thus prevents vibration
or jarring when the slay is working. The action of the spring also tends to return
the guard to normal position when lifted but is not sufficiently strong to effect that
by itself. As soon however as the slay moves forward to beat up the concussion
is sufficient to throw the guard over from the position shown in Figs. 4——5—6 to-
that shown in Figs. 1-2-3.
Having now particularly described and ascertained the nature of the said inven--
and in what manner the same is to be performed we declare that what we
claim is :-
1. A shuttle guard for looms having the several parts constructed and arranged
substantially as and for the purpose described.

page_text: 2. The combination with a movable or pivoted shuttle guard of a spiral or other
spring which holds it steady and a supporting bracket and clutch which engages
therewith substantially as described.
