Abstract

Spring clutch 10, that connects continuously rotating shaft 11 to output shaft 12, is controlled by arbor assembly 13 to produce selective full or half revolutions of output shaft 12. Assembly 13 includes a pair of 180 degrees spaced, laterally-separated stop ledges 14 and 15 that are alternatively engageable with the end of clutch latch plate 16. This is pivoted downwardly upon activation of magnet 17 to allow clutch 10 to wrap down on input shaft 11 and thus cause rotation of shaft 12 and assembly 13. During notation of assembly 13, latch plate guidebar 18 is pivoted laterally by cam groove 19 to displace plate 16 from one surface 14 or 15 to the other so that rotation is terminated after 180 degrees.

Selective Full or One Half Revolution Clutch

Spring clutch 10, that connects continuously rotating shaft 11 to output shaft 12, is controlled by arbor assembly 13 to produce selective full or half revolutions of output shaft 12. Assembly 13 includes a pair of 180 degrees spaced, laterally- separated stop ledges 14 and 15 that are alternatively engageable with the end of clutch latch plate 16. This is pivoted downwardly upon activation of magnet 17 to allow clutch 10 to wrap down on input shaft 11 and thus cause rotation of shaft 12 and assembly 13. During notation of assembly 13, latch plate guidebar 18 is pivoted laterally by cam groove 19 to displace plate 16 from one surface 14 or 15 to the other so that rotation is terminated after 180 degrees. If it is desired to achieve 360 degrees rotation upon a single activation of magnet 17, control plate 20 is displaced rightwardly to move guidebar 18 out of groove 19 so that plate 16 is not displaced laterally. Thus, assembly 13 rotates 360 degrees before plate 16 is encountered.
