Abstract
The present disclosure relates to a ratchet and, specifically, a ratchet head arrangement, or assembly, for a ratchet. The ratchet head arrangement, or assembly, of the present disclosure is directed to the features of a ratchet pawl that balance and transfer the loads and stresses on the internal components of ratchet head mechanism across the components of the assembly to avoid premature failure, or fracture, or avoid isolated point loads on the internal components. Specifically, a ratchet pawl of the present disclosure includes a recessed area dividing sets of teeth for engaging teeth of a ratchet gear in combination with opposing substantially flat stop walls that fully mate with the sidewalls of the interior housing of a ratchet head.
