Abstract
A machine is disclosed which incorporates a timing control for modifying the timing of a starter for feeding work blanks to a forming station and which features a manual control for applying a supplementary rotary input into a spindle operated differential having an output drivingly connected to the starter for effecting a desired change in the timing of starter movements in relation to a circular die fixed to the spindle at the forming station. In addition, a starter drive selector is provided having a manual interlock for selectively adjusting the number of starter operations for each revolution of the spindle and its circular die.

For use in a workpiece forming machine having a spindle rotatably mounted on a fixed frame with a circular die secured to the spindle for rotation therewith and a movable starter for successively feeding workpieces to the circular die at a forming station, a variable starter timing control comprising a differential having a first rotary input drive movable in response to the spindle, a second rotary input drive selectively operable to impart a supplementary input to the differential, and an output drive connected to the starter for operating it in selectively timed relation to rotation of the circular die in accordance with the combined inputs of the first and second input drives.
An assembly usable in a workpiece forming machine for adjusting the operational timing under both stationary and dynamic conditions of a movable starter for successively feeding workpieces to a forming station and comprising a fixed frame, a spindle rotatably mounted on the frame, workpiece forming dies at the forming station including a circular die secured to the spindle for rotation therewith, an adjustable drive mechanism for operating the starter in timed relation to rotation of the circular die, a rotary input driven by the spindle, a driven rotary output for driving the starter drive mechanism, intermediate idler gear means drivingly connecting the rotary input and rotary output, and a second rotary input manually operable for selectively changing the relative angular positions of the first rotary input and the rotary output for adjusting the operational timing of the starter in relation to the circular die.
For use in a workpiece forming machine having a spindle rotatably mounted on a fixed frame with a circular die secured to the spindle for rotation therewith and a starter for successively feeding workpieces to the circular die at a forming station responsive to a cam controlled starter drive mechanism, a starter drive selector comprising a spindle operated, selectively settable cam drive connection to the starter drive mechanism for driving it in a first drive setting and alternatively in a second drive setting different from that established in the first setting, and an interlock connected to the cam drive connection and movable between first and second operating positions to effectively change the drive setting from one to the other of said first and second drive settings.
