Abstract

The throw T of follower arm 10, caused by 180 degrees moving face cam 11, is adjusted by vertical movement of follower roller 12. Bracket 13 is mounted on arm 10 by eccentric 14 and sliding pin 15 thus permitting angular orientation of bracket 13 relative to arm 10 and cam surface 11a. Roller 12 is positionable vertically in slot 16 and held in place by fastener nut 17.

High Speed Shift Mechanism

The throw T of follower arm 10, caused by 180 degrees moving face cam 11, is adjusted by vertical movement of follower roller 12. Bracket 13 is mounted on arm 10 by eccentric 14 and sliding pin 15 thus permitting angular orientation of bracket 13 relative to arm 10 and cam surface 11a. Roller 12 is positionable vertically in slot 16 and held in place by fastener nut 17.

Throw T is adjusted as follows. Cam 11 is positioned at low dwell as shown. Bracket 13 is adjusted by eccentric 14 to cause slot 16 to be parallel with the low dwell portion of cam surface 11a. Cam 11 is rotated 180 degrees to high dwell. Nut 17 is loosened and roller 12 is adjusted vertically up or down to position output pulley 18 to the desired extreme end of throw T. Nut 17 is tightened to retain the parts in their adjusted position.

The adjustment of the high dwell position of follower 10 does not vary the parallel orientation of slot 16 relative to the low dwell cam surface. It does not modify the low dwell limit of throw T.
