Abstract
A lubricating device for a revolving lock stitch shuttle of machines such as sewing and embroidering machines comprises a shuttle body which has a hub portion which surrounds its associated shuttle arbor and which lies adjacent a bearing mounting for the arbor. The hub portion is hollow and defines a lubricating oil chamber between it and the associated bearing and a gap between the shuttle hub portion and the associated bearing is bridged by a fixed ring member which is carried on a bracket which is secured to the bearing. The ring member has an opening therethrough providing an access for a nozzle tube for feeding oil from an external reservoir to the hub recess from when the oil is advanced by the centrifugal force of the rotation of the shuttle to the periphery of the shuttle.
