Combined damper and thread breakage sensor for textile machines

Abstract

A combined damper and thread breakage sensor for use with textile machines includes a housing having a non-conducting medium disposed therein and a first contact and a second contact means immersed in the medium. The second contact extends beyond the housing and is provided with means for guiding the thread in a first position. Upon breakage of the thread the second contact moves to a second position coming into electrical contact with the first contact thereby completing an electrical circuit path of an external circuit. The completed electrical circuit path causes the circuit to shut down the textile machine, thus preventing the fabrication of defective material. The movable contact is provided with a portion which offers resistance to the non-conducting medium thereby additionally functioning to dampen out any sudden and intermittent changes in the thread tension.
