Abstract
This apparatus for coupling and decoupling driving and driven elements includes an overrunning clutch mechanism having complemental parts with members on one part movable in a plane extending radially to the axis of rotation of the parts to engage the members with the second part for effecting a driving connection between the parts, one of the parts being selectively movable axially relative to the elements to interrupt and reestablish the radial registration of the members with the second part, the elements being coupled when registration is established and decoupled when registration is interrupted.
Claims10
Apparatus for coupling and decoupling driving and driven elements, comprising:
- a. pawl and ratchet type clutch means having complemental parts on said driving and driven elements, at least one of said parts being provided with members movable in a plane substantially radial to the axes of said elements to engage the other part and effect a driving relation between said elements, one part of said clutch means being movable axially relative to one of said elements;
- b. means for moving said one part axially of said one element to interrupt and reestablish radial registration of said members with said other part of said clutch means;
- and
- c. resilient means for urging in one direction said means for moving said one part axially of said one element.
Apparatus for coupling and decoupling driving an driven elements, comprising:
- pawl and ratchet clutch means having complemental pawl and ratchet parts respectively on said driven and driving elements, said pawl part being provided with pawls movable in a plane substantially radial to the axes of said elements to engage the ratchet and effect a driving relation between said elements, one of said parts being movable axially relative to the other of said parts, said ratchet being mounted on the driving element for limited radial self-aligning movement;
- and
- means for moving said one part axially to interrupt and reestablish radial registration of said one part with said other part of said clutch means.
Apparatus for coupling and decoupling driving and driven elements, comprising:
- pawl and ratchet type clutch means having complemental parts on said driving and driven elements, at least one of said parts being provided with members movable in a plane substantially radial to the axes of said elements to engage the other part and effect a driving relation between said elements, one part of said clutch means being movable axially relative to one of said elements;
- means for moving said one part axially of said one element to interrupt and reestablish radial registration of said members with said other part of said clutch means;
- a piston supported for rotary movement and carrying the ratchet;
- and
- a cylinder receiving the piston for axial movement therein.

- means for moving said one part axially of said one element to interrupt and reestablish radial registration of said members with said other part of said clutch means;
- a piston supported for rotary movement and carrying the ratchet;
- and
- a cylinder receiving the piston for axial movement therein,
- said piston being connected with the driving element in a manner to provide limited radial floating movement of the piston and ratchet and easy coupling action, said radial floating movement of the piston and ratchet is secured by providing crowned splines between the driving element and the piston and ratchet.
