Improved Shuttle Guard for Looms.
I, WILLIAM WILSON, of Annvale, Keady, in the County of Armagh, Ireland,
Weaving Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved guard for use in looms to prevent the
shuttles from flying out of their proper course when being picked through the shed,
the object being to provide a guard which will be automatic in its action, covering
the path of the shuttle while the latter is flying from box to box and closing up
against the slay cap as the shuttle enters either box and the reed approaches the
fell of the cloth, in which latter position the guard rods are entirely out of the way
of the temples used for stretching the cloth as it is woven.
In carrying out my invention I attach to the slay cap two or more brackets,
preferably two, one at or near each end of the cap-to which are pivoted two
light metal or other rods or their equivalents, which are about the same length as
the reed. As a convenient means of pivoting, the rods are bent up at each end and
a pin passed through the bent ends and the brackets fixed to the slay cap. The
bent ends of each rod are prolonged and are in turn coupled to the forward ends of
two pairs of links the rearward ends of which are coupled to levers-one fixed at or
near each end of a rod, bar or shaft supported at the top of the slay cap. The
rearward ends of the links are so coupled to the levers on the rod referred to that in
operation the guard rods are caused to assume a position about 1 inches from each
other when moved into their protective position and whilst in this position are held
firmly. The shaft on the top of the slay cap is also at one end provided with a
lever, or is bent backwards, and has coupled to it a light rod the lower end of which
is adjustably attached to one end of a lever the other end of which is pivoted to the
forward end of a bracket bolted to the lathe sword. Intermedially this lever carries
a small bowl or roller which is adapted to engage with the upper surface of a
bracket attached to the loom frame, the said surface being so formed as to impart
a rising and falling or backward and forward motion to the guard rods independent
of the ordinary movement of the lathe.
In operation, and assuming the lathe to be midway of its backward stroke the two
guard rods are out from the slay-that is to say they are about one and a half inches
from each other and in a position to prevent the shuttle, which is about to be
picked, from flying out of its proper path during the latter operation--and as the
lathe moves forward the bowl on the lever referred to engages the upper surface of
the bracket attached to the loom frame and causes the rods to be brought up against
the slay cap and out of the way of the temples as the slay approaches the fell of the
cloth. When the slay is about half-way on its backward stroke the rods again
resume their protective position.
By the means I have described the guard rods can be set very close to the warp
and yet are not in the way of the temples; and in addition are capable of being
folded close against the slay cap where they form no obstruction to the weaver
when drawing in ends or performing any other operation about the reed.
[D.Jl

page_text: guard rods C are out from the slay, as shown on Fig. 1. That is to say they are
about 1 inches from each other and in a position to prevent the shuttle, which
is about to be picked, from flying out of its proper path during the latter operation.
As the lathe moves forward the bowl O, or setscrew, on the lever L engages the
upper surface of the bracket M attached to the loom frame, thus lifting the rod K
and causing the rods C to be brought up against the slay cap, as shown in Fig. 2,
and out of the way of the temples as the slay approaches the fell of the cloth. When
the slay is about half-way on its backward stroke the rods again resume their
protective position.
By the means I have described the guard rods can be set very close to the warp
and yet are not in the way of the temples: and in addition are capable of being
folded close against the slay cap where they form no obstruction to the weaver
when drawing in ends or performing any other operation about the reed. They may
be held against the slay cap for any of these purposes by a small catch pivoted on
the latter.
It will, of course, be understood that the details of my invention may be departed
from without affecting the spirit of the invention.
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:-
1. An automatic shuttle guard for looms consisting of two rods or their equiva-
lents pivoted to the slay cap and so operated by links and levers through the action
of the lathe that they may cover the shuttle race whilst the shuttle is being picked
and close against the slay cap as the shuttle enters the box substantially as and for
the purposes described.
2. The general arrangement and combination of parts forming my improved
automatic shuttle guard substantially as described and shown in the accompanying
drawings.
