ABSTRACT:
The yarn condition sensing device is comprised of a plurality of thin flat forks pivoted at one end thereof between a plurality of closely spaced apart plates protruding from one side of a reed. The opposite end of each fork is provided with a yarn guide aperture for sensing a plurality of yarns under tension. A pair of parallel electrical contacts are secured along the top and bottom edges respectively of the reed which will produce a suitable warning or control signal if contacted by the pivoted fork upon variation in the tension of a single yarn. If the tension of a yarn increases undesirably, the fork engaged with said yarn will be pivoted upwardly into engagement with the electrical contact along the top edge of the reed. if a yarn should break, the fork engaged therewith will fall downwardly into engagement with the electrical contact disposed along the bottom edge of said reed. A plurality of holes are located in a line along the end of the fork opposite the yarn receiving aperture for selectively varying the pivot axis of said forks and for the reception of a suitable locking pin.
