Abstract

A stop motion for detecting the interruption of yarn travel therethrough comprising a pivotally mounted fly wire restrained in a first position by the yarn traveling through its guide means, and biased for pivotal movement away from said first position when the yarn travel is interrupted due to its running out or breakage. The means biasing the fly wire apply minimum torque thereto when the fly wire is restrained by the yarn and such torque progressively increases when the fly wire is freed from its restraint whereby it acquires gradually increasing pivotal momentum for providing firm wiping engagement of the stop motion switch, said switch being defined by a contact element movable in unison with the fly wire and another contact element carried by the housing, the latter's position being movable for selectively adjusting the point of engagement of said contact elements.
