Abstract

This fast-action roller clutch has an outer housing 10 which is driven directly from a motor, not shown. Housing 10 is a driving member of the clutch. Driven member 16 is coaxially mounted and has flats underneath rollers 14. A third member 12 holds rollers 14 and rotates coaxially with member 16. When the clutch is disengaged, springs 22 are in tension and are held that way by link 24. This pushes against dog 18 on member 16 and link 26. Such pushes against dog 20 on member 12 and there is clearance between rollers 14 and housing 10.

Clutch with Linkage and Counting Mechanism

This fast-action roller clutch has an outer housing 10 which is driven directly from a motor, not shown. Housing 10 is a driving member of the clutch. Driven member 16 is coaxially mounted and has flats underneath rollers 14. A third member 12 holds rollers 14 and rotates coaxially with member 16. When the clutch is disengaged, springs 22 are in tension and are held that way by link 24. This pushes against dog 18 on member 16 and link 26. Such pushes against dog 20 on member 12 and there is clearance between rollers 14 and housing 10.

To engage the clutch, link 26 is pulled upwardly and springs 22 move member 12 with respect to member 16 and wedge rollers 14 between housing 10 and member 16. To disengage the clutch after a complete cycle, link 26 is dropped, engaging dog 20, stretching springs 22 and disengaging rollers 14 from housing 10 while member 16 continues to rotate because of its inertia. Dog 18 drives past link 24, which falls down and latches member 16.

The remaining mechanism, when the clutch is disengaged, is required to count a specific number of revolutions of the clutch, e. g., five, and to move links 24 and 26 for engagement and disengagement. When magnet 36 is de- energized, arm 28 is pulled away, releasing link 26 upwardly and engaging the clutch. Cam 34 is a sensor geared to the output shaft on the clutch so that it rotates once for every five revolutions of the clutch output shaft. As cam 34 begins t...
