Class Information
Number: 254/223
Name: Implements or apparatus for applying pushing or pulling force > Portable implements or apparatus for tensioning flexible material or for extracting stumps or poles > Including rotatably driven drum for engaging either material or force transmitting cable > With means for preventing or retarding rotation in at least one direction > Ratchet wheel or formation and pawl
Description: Implements or apparatus wherein the means consists of either (a) a wheel having teeth located on its perimeter, the wheel being rotatably interconnected to the drum, and a pawl which interlocks with the teeth in one direction of the wheel"s rotation to prevent movement of the drum and which disengages from the teeth in the other direction of the wheel"s rotation to allow movement of the drum, or (b) a stationary ratchet formation having teeth located on its perimeter and a pawl connected to the drum which revolves around an axis when the drum is rotated; the pawl interlocks with the teeth in one direction of its travel to prevent movement of the drum and disengages from the teeth in the other direction of its travel to allow movement of the drum.
