Abstract
A spindle brake apparatus for add on attachment to automatic Swiss screw machines, comprising an idler pulley release assembly, a spindle brake assembly and a cam actuated control assembly employing the existing cam shaft timing and control means of such machines to stop spindle rotation so that cross milling operations may be performed. The apparatus is operated by compressed air in response to cam actuated valves to first release an idler pulley then apply the brake to stop spindle rotation. After a stationary operation is performed, compressed air is released thereby releasing the brake followed by reengagement of the idler pulley to reestablish spindle rotation.
