ABSTRACT:
A tufting machine having a broken yarn detector including a multiplicity of yarn engaging fingers mounted in a support block secured to the frame of the tufting machine. Each finger has an eyelet at one end for receiving a strand of yarn and is pivotably mounted on a rod externally of the mounting block so that the fingers may be supported by the yarn in a raised position during normal operation, but pivotably drops when the yarn is broken. The rod is secured in position by a number of clamping blocks attached to the mounting block, the clamping blocks also having slots aligned with the slots in the mounting block at the location where the clamping blocks are secured for receiving the external ends of the fingers so as not to impede the pivotable movement. A light generator and a photoconductive receiver are mounted for detecting when a finger drops, the finger interrupting the transmission of the light beam to provide a signal which may be used to stop the tufting machine.
