This design consists, "with the beam consisting, essentially, of the forwardly-converging branches at their forward ends and having the downwardly and forwardly curved branches at their rear ends and rack-teeth" (lines 100-104). It further consists "of the feet comprising parallel branches pivotally connected to the ends of the downwardly and forwardly curved branches of the beam branches, the gravitating pawls pivoted between the upper ends of the feet branches and adapted to engage the rack-teeth of the beam branches" (lines 1-8).
