Abstract
A needle thread wiping device having a mounting bracket supported beneath the head behind the needle bar. The mounting bracket supports a pair of shafts which extend laterally therefrom towards both sides of the head. A thread wiper assembly may be fastened to one side or to both sides of the mounting bracket by means of a lever which may be affixed to a forwardly located shaft by a set screw. One end of the lever carries a sleeve. A link is carried on the second shaft, the link also carrying a sleeve, both sleeves slidably supporting therein a thread wiper having a hooked end. A back plate is provided having a curved slot supported on the second shaft and having a pivotal connection to the sleeve in the end of the lever. The thread wiper also has a connection to the back plate. If the lever is made to rotate, the thread wiper moves with its motion, as does the back plate which causes the hooked end of the thread guide to travel a path from outside of the stitching area to a position across the path of the sewing needles and the return to initial position for carrying a cut thread out of a work material.
