ABSTRACT:
A yarn tensioning device for the continuous application of uniform tension to yarn of indefinite length as it runs through the device, the latter being of the type in which a freely rotatable ball serves to apply the tension to the yarn. The device has a housing with a cylindrically shaped yarn passageway extending vertically therethrough and in which a pair of spaced yarn eye guides of ceramic material are positioned. A ball is disposed in the passageway between the inserts so as to be seated atop the opening in the lower yarn eye guide. The diameter of the passageway is uniform and the wall of the housing is provided with a slot extending therethrough so that the yarn may be threaded through the slot and through each of the inserts thereby to thread the device with the yarn extending through the passageway and around the ball. The housing is provided with horizontal and vertical extending brackets by means of which the device may be mounted upon similarly extending surfaces. The housing is provided with diametrically opposed slots at its upper end for the insertion therethrough of a suitable lever to conveniently remove the upper yarn eye guide from the housing.
