Complete Specification Left, 23rd Sept., 1890-Accepted, 6th Deo., 1890
PROVISIONAL SPECIFICATION.
Improved Automatic Shuttle-guards for Looms.
We, ROBERT SMYTH, of Tullyelmer, Armagh, Co. Armagh, Ireland, Linen Manu-
facturer, and JAMES MIDDLETON, of same place, Mechanic, do hereby declare the
nature of this invention to be as follows :—
This invention, has for its object, the prevention of shuttles flying out, when the
looms are in operation, whereby the operatives, are in much danger of meeting with
serious accidents, such as the losing of an eye, and other disfigurements of the
face &c. Also much damage is often done to the cloth being woven.
We accomplish our object by placing a guard bar across the entire reed space,
completely covering shuttle race, and just touching yarn when the shade is sprung
and shuttle passing, then rising and giving weaver ample room to regulate yarn, and
keeping that position while passing over temples, weft fork, and the hand if feeling
the cloth, or holding disconnected yarn, and continues to act while the loom is
in motion. It is attached to three radius rods at each end, actuated by motion
of sword, and entirely free of hand rail.
