PROVISIONAL SPECIFICATION.
An Improved Automatic Shuttle Guard for Looms for Weaving.
CORNELIUS MARSHALL Rose Cottage Deane Road Bolton Lancashire
Weaving Manager do hereby declare the nature of this invention to be as
follows:-
On the face of the sley cap I. carry a wire guard by means of two brackets, one-
at each end, in which the guard swivels. I attach a spring to the sley cap one
end of which goes behind the guard, and having an outward thrust holds the
guard in position when the loom is in operation. At one end of the wire guard.
I bend the wire towards the sley cap, the bend making an angle of about 80° with
the guard. I connect this bend to a small lever having its fulerum in the middle,
and which is placed on the top of the sley cap.
When this lever is operated the
guard is drawn underneath the sley cap. To the back end of this small lever
I attach a wire which I let fall parallel to the sley sword, and which terminates
with a spiral spring just above the rocking rail. This spring enables me to
disconnect the wire from the small lever, and the sley cap can then be conveniently
removed. This wire at its spring end I connect to a second lever having its
fulcrum in the middle, and the farther end of this lever I connect to an L lever
which is carried by a bracket fixed to the loom frame. This bracket is made with
a slot which allows the stud which carries the lever to be moved for the purpose
of adjusting the throw of the guard. The farther end of the L lever is constructed
with a projecting piece which goes behind the setting on rod next to the loom
frame. When the setting on rod is knocked off, and the loom is stopped, this.
☐ lever is operated by the setting on rod and by means of the two connecting
levers the guard is pulled underneath the sley cap. When the loom is restarted
the lever is relieved and the spring which is attached to the sley cap, and which
gives an outward thrust to the guard, forces the guard into its outward position.
In order to have the guard pulled in when the loom is in motion, I connect the
second lever to an Llever one end of which is near the front frame of the loom,
and which can be operated by the weaver's foot.

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 :-
On the face of the sley cap A Fig. 11 carry a wire guard B by means of the
brackets C C¹ in which the guard swivels. I attach a spring N to the sley cap
one end of which is connected with the guard at B' and which pulls the upper
bend of the guard against the sley cap, and holds it in position. At the opposite

page_text: end of the guard I bend the wire towards the sley cap as shown at B' Figs. 1, 2
& 3. I connect this bend by means of a wire F to a small lever D Figs. 1 & 2
the other end of which is coupled to the connecting wire G which in turn is
connected to the lever J by the spring H, the opposite end of this lever being
connected to the lever L by the wire K. One projecting end of the lever L lies
against the inner side of the setting on rod T.
The guard is operated in the following manner. When the setting on rod is
pushed away from the frame of the loom S in the act of starting the loom the
guard is liberated and the spring N pulls it into its working position. When the
setting on rad is knocked off and the loom is stopped the setting on rod forces
the end of the lever L towards the frame of the loom and actuates the lever J
which in turn actuates the lever D on top of the sley cap which by its connection
with the bent part of the guard B¹ pulls the guard B underneath the sley cap as
shown by the dotted lines Fig. 3.
:
Another method by means of which the guard is operated is shown at Fig. 4.
Instead of the lever D I substitute the lever V, one end of which lies behind
the upper bend of the guard as shown at W Figs. 4 & 5. When G is pulled down
when the loom is knocked off as before described the lever V forces the upper
bend of the guard in the outward direction which forces the guard B underneath
the sley cap as shown by the dotted lines at W Fig. 4. 1 use the spiral spring H
for the purpose of easily disconnecting the wire G from the levers D or V when it
is required to take off the sley cap. I also operate the guard B independently of
the setting on rod by means of a foot lever P as shown in Figs. 1 & 3. P is &
board bolted to the brackets Q Q which swivels in brackets fixed on the front rail
of the loom. On one end of this board P I bolt a bracket R one end of which is
turned at a right angle and is projected under the outer end of the lever J. When
the foot of the weaver is pushed forward the board P is pressed back, and actuates
the levers D or V and as before described forces the guard B underneath the sley
cap. When the foot is taken away the guard assumes its former position by means
of the spring N as before described.
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 ia :
1st. To operate the guard B by means of a lever I placed at the foot of the
sley sword, which lever is connected to a second lever fixed on the sley cap, one
end of which lever is connected to, or lies behind, the upper bend of the guard.
2nd. To operate the guard without its being attached to the actuating part
connected with the setting on rod, the upper bend of the guard simply lying
against the lever on the sley cap as at V Figs. 4 & 5.
3rd. To operate the guard by the foot, by means of a foot lever which is
connected to the guard,
