ABSTRACT:
A continuous drive ratchet tool apparatus is comprised of drive disks adapted to be connected in driving engagement with a bolt head or nut threaded fastener, a disk housing having an opening extending through the housing and a bearing channel communicating with the opening, one of the drive disks being rotatably received in the opening, and a ball bearing spring biased into engagement between the disk housing opening and the one drive disk. The bearing selectively establishes a continuous driving engagement between the disk housing and the drive disk for rotating a threaded fastener in a first direction by connecting the drive disk to the fastener and rotating the disk housing in the first direction. The bearing then permits the housing to override its connection to the threaded fastener allowing the fastener to remain stationary when the disk housing is rotated in a second direction opposite to the first. The bearing also prevents any lost motion between the threaded fastener and the apparatus when rotating the apparatus to again rotate the fastener in the first direction.
