PROVISIONAL SPECIFICATION.
An Improved Shuttle Guard for Looms.
CORNELIUS MARSHALL 66 Wigan Road Bolton Lancashire do hereby declare-
the nature of this invention to be as follows:-
Along the sley cap, and by preference on the underside of the cap and in front
of the reed I support by means of brackets a rod, or wire which is cranked at each
end, and which cranks carry the shuttle guard. The guard is made the required
length, and each end is bent at an angle of 90° the bent parts being about 5 inches
long. These bent ends I twirl so as to form rings round the crauks at each end of
the cranked rod, by which means I obtain a swivelling motion of the guard. After
forming this ring I continue the ends of the guard for about 2 inches, and again
bend each end about 1 inch long at an angle of 90° which brings this parallel to
the guard. These ends are movable along slots which are formed in the brackets
which support the cranked rod. The guard is thus carried by the cranked rod, each
end of the guard moving in slots. By this construction I obtain the following
movement of the guard. When the loom is started the guard automatically falls
into the required position over the shuttle race, the bent ends of the guard falling
to the bottom of the slots in the brackets. The cranks which carry the guard are
now at an angle of 90° with the sley cap. When it is required to clear the face of
the reed the operator presses the guard, which causes the cranks which carry it to
assume a vertical position, by reason of which movement the guard not only rises,
but is drawn in towards the reed, and going under the sley cap is no longer in
sight, and the reed is entirely cleared.
Dated this 2nd day of February 1894.

An Improved Shuttle Guard for Looms.
CORNELIUS MARSHALL 66 Wigan Road Bolton Lancashire Weaving Manager
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
Fig. 1. A is the sley cap on which the guard D is fixed. The brackets F F¹
carry the rod B which is cranked at each end as shown at C C₁ Figs. 1 & 2.
guard D is carried by the cranks CC' and when operated will swivel on these as
centres. The return ends of the guard at E E¹ project into the slots of the
brackets F F. When the loom is in process of weaving, the guard D is down as
shown in Figs. 1 & 4 and covers the shuttle as it passes from box to box, in such a
manner as either to prevent the shuttle from flying out; or in case it does fly out
so to divert its course as to be less dangerous to the operator. When the loom
is stopped the guard D is pressed by the hand and the cranks C C¹ of the cranked
rcd B which are at an angle of 90° with the sley cap, rise to an almost perpendicular
position against the face of the sley cap as shown in Figs. 2 & 3. This motion of
the cranks cause the projecting ends of the guard E E' to rise in the slots of the
brackets F F and the guard is forced to the back of the cranked rod B, and passes
out of sight of the operator, and the reed is cleared from the impediment of the
Pi 27

page_text: guard. The spring G keeps the guard in this position until the loom is again
started, when the momentum of the loom overcomes the resistance of the spring G,
and throws the shuttle guard D forward, which then falls to its original position as
shown in Figs. 1 & 4.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
That by means of a cranked rod as shown in Figs. 1 & 2 I carry a shuttle
guard D which when pressed by the hand clears the face of the reed by rising
until it assumes a position underneath the sley cap, and is out of sight of the
operator.
