An Improved Loom Shuttle Guard.
RICHARD PENDLEBURY, 5A, East Street, Preston Lancashire, Mechanical
Engineer, JOSIAH TURNER, 268 St. Paul's Road, Preston, Lancashire, Weaving
Manager, do hereby declare the nature of this invention to be as follows:-
A rod of metal held in a horizontal position in front of, and parallel to the reed
in looms for weaving textile fabrics. The said rod being close too, and just above
the yarn, when the loom is at work and the shuttle passing through the shed, owing
to this position of the rod, the shuttle is prevented from escaping or flying from
its proper course.
The rod is bent at each end in the form of a crank, so that when the rod is
suspended from the cranked ends, the rod itself lies vertically under the points of
support. These supports consist of two brackets, fixed one at each end, and on
the front side of the slay-cap, the centre of suspension of the rod being a short
distance in front of the slay-cap, so that the rod is free to oscillate about these
points as centres.
When the rod hangs vertically under these centres, it is then in its lowest
position, this being the position it is to occupy when the loom is at work.
It is held firmly in this position on one side by stops attached to the brackets,
and on the other side (the side nearest to the reed) by a flat steel spring or bracket,
projecting in front, and somewhere about the middle of the slay-cap.
When the loom is not at work, and the rod required to be out of the way of the
weaver, a slight pressure of the hand upon the rod is sufficient to depress the spring
and push the rod to a higher position, close up to the slay-cap and out of the way;
where it will remain so long as the loom is not in motion.
The higher position now assumed by the rod is due to the centre of suspension
being placed a short distance in front of the slay-cap.
Immediately the loom is put in motion the momentum of the slay together with
gravity brings the rod again to its lowest position. ⚫

An Improved Loom Shuttle Guard.
RICHARD PENDLEBURY 5A, East Street Preston, Lancashire, Mechanical
Engineer, JOSIAH TURNER 268 St. Paul's Road, Preston, 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 :-
A rod of metal held in a horizontal position in front of and parallel to the reed
in looms for weaving textile fabrics.
The said rod being close too and just above the yarn, when the loom is at work
and the shuttle passing through the shed, owing to this position of the rod the
shuttle is prevented from escaping or flying from its proper course.

page_text: The rod is bent at each end in the form of a crank, so that when the rod is
suspended from the cranked ends the rod itself lies vertically under the points of
support.
These supports consist of two brackets, fixed one at each end, and on the front
side of the slay-cap, the centre of suspension of the rod being a short distance in
front of the slay-cap, so that the rod is free to oscillate about these points as
centres.
When the rod bangs vertically under these centres it is then in its lowest position
(this being the position it is to occupy when the loom is at work).
It is held firmly in this position on one side by stops attached to the brackets,
and on the other side (the side nearest the reed) by a flat steel spring, or another
bracket, projecting in front, and somewhere about the middle of the slay-cap.
When the loom is not at work, and the rod required to be out of the way of the
weaver, a slight pressure of the hand upon the rod is sufficient to cause the rod to
assume a higher position close up to the slay-cap and out of the way, where it will
remain so long as the loom is not in motion.
The higher position now assumed by the rod is due to the centre of suspension
being placed a short distance in front of the slay-cap.
Immediately the loom is put in motion, the momentum of the slay together with
gravity bring the rod again to its lowest position.
In the accompanying sheet of drawings,
Fig. 1. is a front elevation of the slay-cap with guard attached, about one fourth
full size, showing the guard in its position, when the loom is at work.
Fig. 2. is a plan of the slay-cap and guard also in its position when the loom is
at work.
Fig. 3. is a section through A B Fig. 1. showing the cap and guard about one
half full size. This view shows the middle bracket supporting the rod in the
middle, the dotted lines show the rod in and the full lines show it out.
Fig. 4. is also a section through A B Fig. 1. about one half full size. This
view shows the middle bracket bent back and let into the slay-cap.
When the bracket shown in Fig. 3 is used the rod is then straight, but when the
bracket shown in Fig. 4 is used the rod is bent in the middle as shown in the
drawings. The action is the same in both cases.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1st. An improved loom shuttle guard supported from points a short distance in
front of the slay-cap, and 2nd a bracket, placed about the middle of the slay-cap to
hold the guard in position when both in and out, substantially as described and
shown in the drawings for the purpose specified.
