Definitions

from The Century Dictionary and Cyclopedia

  • Teeth having one side radial, or nearly so, and the other side much inclined. A pawl, dog, or detent can slip over the inclined side but will catch on the radial side, thus permitting the wheel having such teeth to revolve in one direction only.
