Patent number: 5203651Abstract: A tapping attachment for driving a tapping spindle constructed to be adapted for both direct drive and reverse drive of the spindle. The drive of the spindle is by way of a resiliently mounted dog ring having rigid radially extending drive dogs, extending radially outwardly and inwardly from a drive ring. The driving dogs are rigid, having slanting sides to accommodate clutching engagement and disengagement. Clutching engagement and disengagement occur as a result of relative axial movement as between the attachment and the drive spindle. The drive spindle has a central bore in which is provided an insert member having an axial bore which is connected to a flexible tube within the bore of the spindle, which accommodates relative axial movement, the flexible tube communicating with a similar bore in a tap itself. These bores provide a channel for continuously supplying coolant to the machine and to the spindle itself.Type: GrantFiled: June 14, 1991Date of Patent: April 20, 1993Assignee: Tapmatic CorporationInventor: Allan S. Johnson
