PROVISIONAL SPECIFICATION.
Improved Shuttle Guard in Looms for Weaving.
CORNELIUS MARSHALL 66 Wigan Road Bolton, Lancashire Weaving Manager,
do hereby declare the nature of this invention to be as follows:-
A wire of suitable strength is so arranged as to form a shuttle guard in front of
the reed, which prevents the shuttle from flying out of the warp shed when the
loom is in motion. I effect this by the undernoted construction. About 2" in
front of the sley swords, and about 2" above the line of the sley sword swing rail,
I place two levers each carried by a bracket attached to the frame of the loom,
one lever being in front of the right hand sley sword, and the other in front of
the left hand sley sword. These Llevers are connected by a rod which causes a
simultaneous movement when they are operated by means of a simple lever which
is connected to the setting on rod.
The wire guard which runs along the face of the sley cap I double over to the
back of the sley cap and carry each end down to the levers which are in front
of the sley swords. When the loom is set in motion the L levers are so operated
from the setting on rod as to cause the guard to fall until it is immediately above
the shuttle as it passes from box to box. When the loom is stopped the guard
rises to its original position close to the bottom edge of the sley cap. When
the loom is in motion, the guard, by reason of being connected with the L levers
in front of the sley swords falls as the sley comes to the back centre until it just
clears the shuttle, and rises as the sley comes to the front centre, and clears the
temples. By the foregoing construction I so apply a shuttle guard as not to be
an impediment to the weaver.

COMPLETE SPECIFICATION.
Improved Shuttle Guard in Looms for Weaving..
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 :-
This invention relates to an improved automatic shuttle guard by means of
which I prevent the shuttle flying out of the warp shed as it is thrown from
side to side in the process of weaving. This prevention I effect in the following
manner.
From the levers B & C which by preference I place about 2" in front of the
sley swords K K I project the shuttle guard A, taking the wire bb' from the
front of the sley swords K K to the back of the sley, bringing the wire as at a a¹
over the sley cap I to the face of the sley cap. The levers B & C are connected
by the rod E by which means they obtain a simultaneous movement.
The shuttle guard is operated in the following manner. When the loom is put
in motion by pushing on the setting on rod G, the bracket H which is attached to
the setting on rod, actuates the lever F, which in turn operates upon the levers C & B
D

page_text: causing the shuttle guard A to become depressed as shown in Fig. 1 until it barely
clears the shuttle as it passes from box to box. When the setting on rod G is
knocked off, the action of the levers above described are operated in a reverse
manner, and causes the shuttle guard A to rise to the under edge of the face of
the sley cap 1 as shown by the dotted lines at L.
It will be seen by Fig. 2 Sheet 1 that in consequence of the guard A being
connected by the L levers C & B about 2" in front of the sley sword K, and
these levers being carried by the brackets D affixed to the frame of the loom,
that, as the sley moves to the back centre, the guard A gradually falls to the
required position, and as the sley moves to the front centre the guard A rises
about and clears the temples. By this motion I am enabled to work with the
guard close to the shuttle as it traverses the shuttle race, and so prevents it rising.
out of the warp shed.
?
Fig. 3 Sheet 1 shows the position of the guard A at L when the loom is
stopped, and with the guard in this position the weaver is able to draw the threads
through the reed, and to manipulate the shuttles without any impediment from the
guard.
Another method by which I effect the movement of the shuttle guard A is
shown on Sheet 2, Figs. 4, 5 & 6. The shuttle guard A1 connect at to
projecting levers N & O which are affixed to the rod M. When the loom is put
into motion by the setting on rod G being pushed to the required position, the
lever S is actuated, which in turn operates the rod R which is connected at T to
the rod Q and the projecting lever P which is attached to the rod M, and the
guard A. becomes depressed and covers the shuttle as it passes from box to box.
When the setting on rod G is knocked off the above mentioned levers are reversed
and the guard A rises to the position as shown by the dotted lines at L.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed 1 declare that what I
claim is;
Also
1st. An improved automatic shuttle guard which is operated from each end of
the guard by means of levers, as shown by the levers B & C Fig. 1 Sheet 1.
as shown in Figs. 4 & 6 Sheet 2, the guard is operated from each end by being
connected to the projecting levers N & O which are affixed to the bar M.
2nd. By placing the actuating levers B & C in front of the sley swords K K
as shown in Figs. 1 & 2 Sheet 1 I obtain a rising and falling motion of the guard A
as the sley oscillates in the process of weaving.
