DEFINITION

Classification: 74/144

(under subclass 111) Devices, adapted to form parts of more complex intermittent grip mechanisms and to impart step-by-step motion directly to a unidirectionally driven member.

(1) Note. The line between these subclasses and Class 192, Clutches and Power-Stop Control, subclass 41, with respect to one way clutches and clutch operators is as follows: Class 192, will take the clutch, per se, with or without the clutch operator. The inclusion of additional elements; e.g., a holding pawl for the part driven by the clutch, will cause classification in this class (74).

575, for pawls and ratchets, per se.

81, Tools, 58+, for clutched head wrenches or screwdrivers, and subclasses 28+ for a ratchet bit stock.

188, Brakes,

82.1+, for brakes applied to elements rotating relative to stationary elements to prevent retrograde rotation while allowing forward rotation.

192, Clutches and Power-Stop Control, for one way clutches and actuators, and see (1) Note supra.

254, Implements or Apparatus for Applying Pushing or Pulling Force,

108+, 206+, and 237+ for pawl operated step-by-step traveling bar type implements or apparatus.

368, Horology: Time Measuring Systems or Devices,

59+, for secondary electric clock mechanism.

401, Coating Implements With Material Supply,

65+, for a pencil or the like, including a chuck for advancing a piece of lead step-by-step to compensate for attrition.
