Reversible Linear Clutch Mechanism

The clutch mechanism provides incrementing motion in either direction in steps of 0.1 inch, for example, to a driven member 10 which is suitably supported for such movement and which may be attached to any desired driven device, not shown.

The driven member 10 is disposed in a frame 12 and is backed by roller 13 carried by frame 12. Frame 12 is movably mounted and is reciprocated in opposite directions for travels of 0.1 inch, for example, by a wobble plate 14 which is driven by a drive motor, not shown. Wobble plate 14 is disposed between rollers 16 and 18, which are mounted on frame 12 on fixed centers. Member 10 is provided with a central land 20 connected with spaced lands 22 and 24 on one end of the member 10 and with a central land 26 on the other end. A central slot 28 defines the lands 22 and 24, and edge slots 30 and 32 define land 26.

Rollers 34 and 36 extend through opposite slots 37 in frame 12. Roller 34 is provided with cylindrical land portions 38 and 40, and roller 36 is provided with a cylindrical land portion 42. A roller engaging element 44 is oscillatably disposed within frame 12 by a shaft 46. Element 44 is provided with inclined ramps 48 and 50 adapted to make contact, respectively, with land portion 42 on roller 36 and land portions 38 and 40 on roller 34. A yoke 48 is swingably disposed on shaft 46 and has a pin 50 that engages opposite edges of a notch 52 provided in element 44. A spring 54 extends betwe...
