Abstract
A coupling mechanism comprises driving means 12 selectively engaged by driven means 13. The driving means 12 includes an active driving sprocket 15 engaged by a drive chain. The positional relationship of the sprocket 15 with respect to the drive chain is selectively adjustable through a clamp mechanism 21. Locking means 139, 141 preclude the driven means 13 from rotating when the driving means 13 is disengaged from the driving means 12. The positional relationship of the locking means 139 is adjustable relative to coupling drive pins 129.
Claims15
A coupling device for selectively connecting driving machinery to driven machinery and for selectively imparting motion to said driven machinery, said coupling device comprising:
- support means;
- driven means mounted in said support means;
- driving means, for imparting motion to said driven means when said driven means engages said driving means, said driving means having a first portion thereof engaged by a drive chain and a second portion thereof selectively engageable with said driven means, said driving means second portion being connectable to said driving means first portion, said driving means second portion comprises:
- connector means adapted to selectively connect said driving means second portion to said driving means first portion so long as the torque of said driving means does not exceed a predetermined limit;
- carriage means whereon said connector means is mounted;
- hub means adapted to be engaged by said driven means;
- and,
- clamping means, said clamping means being secured to said hub means and to said carriage means, said clamping means having means for adjusting the angular relationship of said carriage means with respect to said hub means, and thereby means to permit the adjustment of the positional relationship of said driving means first portion connectable to said driving means second portion with respect to said drive chain engaging said driving means first portion.
A coupling device for selectively connecting driving machinery to driven machinery and for selectively imparting motion to said driven machinery, said coupling device comprising:
- support means;
- driven means mounted in said support means;
- driving means;
- means for selectively engaging said driven means with said driving means so that said motion is imparted to said driven means when said driven means engages said driving means;
- and,
- locking means for preventing rotational motion of said driven means when said driven means is disengaged from said driving means, said locking means comprising at least one member on said support means and at least a corresponding mating member on said driven means, said member on said support means and said corresponding member on said driven means being adapted to matingly engage when said driven means is translated toward said support means and away from said driving means;
- and,
- wherein said driven means has said engaging means thereon for selectively engaging said driving means, and wherein the angular position of said corresponding mating member on said driven means is selectively adjustable with respect to the angular position of said engaging means.
