I, PERCY HENRY MARRIOTT of Portland Street, Manchester in the County of
Lancaster, Manufacturer do hereby declare the nature of this invention to be as
follows
My invention relates in looms for weaving and consists in an improved safety
apparatus or guard for preventing shuttles flying out of the shed or from the loom
during weaving and injuring the operatives in the weaving room or damaging the
warp.
My improved guard consists of a flat bar or several flat square or round bars
attached by means of hinges to the front of the slay above the reed, the bar or bars
being riveted or otherwise fixed to one part of each of such hinges while their second
While the loom is working,
parts are fixed to the slay by screws or equivalent means.
the bar or bars stand out from the slay in a slanting direction parallel or approximately
parallel to the lifted warp threads when the shed is formed and are held in this position
by spring blades pressing upon flat surfaces formed on the bosses of the movable
parts of the hinges to which the bar or bars are fixed. When a shuttle deviates from
its proper course through the shed in an upward direction, it strikes against the guard
and is thrown downwards and its motion is arrested, so that accidents to persons or
machinery resulting from the flying out of shuttles are prevented. When the loom
is stopped for replacing the shuttle or for other purposes, the guard can be turned
upwards so as to lie against the front of the slay out of the weaver's way, and is held
in this position by the spring blades pressing against other flat surfaces formed on the
bosses of the movable paris of the hinges which carry the guard bar or bars. The
spring blades are attached to the fixed parts of the hinges by screws or rivets or to
the slay.

Lancaster, Manufacturer 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 :—
My Invention relates to looms for weaving and consists in an improved safety
apparatus or guard for preventing shuttles flying out of the shed or from the loom
while the weaving proceeds and injuring the operatives in the weaving room or
damaging the warp.
My improved guard consists of a flat bar or several flat or square or round bars
attached by means of hinges to the front of the slay, the bar or bars being riveted or other-
wise fixed to one part of each of such hinges while the second parts of said hinges are
fixed to the slay by screws or equivalent means. While the loom is working, the bar
or bars stand out from the slay in a slanting direction parallel or approximately
parallel to the lifted warp threads when the shed is formed and are held in this position
by spring blades pressing upon flat surfaces formed on the bosses of the movable parts
of the hinges to which the bar or bars are fixed. When a shuttle deviates from its
proper course through the shed in an upward direction, it strikes against the guard
and is thrown downwards and its motion is arrested, so that accidents to persons or
machinery resulting from the flying out of shuttles are prevented. When the loom
is stopped for replacing the shuttle or for other purposes, the guard can be turned
upwards so as to lio against the front of the slay out of the weavers way and is held
in this position by the spring blades pressing against other flat surfaces formed on the
bosses of the movable parts of the hinges which carry the guard bar or bars. The
spring blades are attached to the fixed parts of the hinges by screws or rivets or to
the slay. On the sheet of drawings appended hereunto figure 1 shows a front view of
one of the hinges with part of the slay and guard bar, figure 2 a cross section and figure 3
a top view of the same in the positions the parts occupy while the loom is working;
figure 4 a front view and figure 5 a cross section of the hinges and other parts in the
positions they occupy when the guard is turned upwards against the slay. Similar
letters of reference denote similar parts on the different figures a is the slay top to
which the hinge is fastened by means of the bolt 6 or equivalent means. d is the
fixed or external part of the hinge with two lugs d¹ d² and e the moveable or internal
part, to which the bar fis riveted. Instead of a single flat bar f two or more bars may
be used or the bar or bars may be square or round instead of being flat. g is the
spring blade fixed to the part of the hinge by means of the screw or equivalent
means, which presses against the flat part formed on the boss of e and holds the latter
in the position shewn on figures 1, 2 and 3.

Projections may be formed on the part d against which the part e rests when held
by the spring in this position. When the guard is turned up, the spring g presses
upon another flat on the boss of e and holds it in the position shewn on figures 4
and 5. Two or more of these hinges are fixed on to the slay for supporting the guard
bar or bars. Instead of the part of the hinge fixed to the slay top being the external
part of the hinge with two lugs d¹d it may be the internal part and have a single lug,
while the movable part forms the external part and has a slotted boss or two lugs
for receiving the said lug. In this case two spring blades or a broad spring blade
slotted at the lower end to pass over the said lug is employed.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
The construction of hinged shuttle guards for looms with spring blades for holding
them in their positions substantially as herein before described and illustrated by the
drawings.
