Abstract
An improved ergonomic hand throw arm for use in conjunction with a railroad switch machine includes an elongated shank and a head disposed thereon. The shank includes a longitudinal axis, and the head includes a first opening and a second opening that are each offset in opposite directions from the longitudinal axis. The head includes an elongated rib that is disposed between the first and second openings and that extends in a direction that is substantially parallel with and may be in register with the longitudinal axis of the shank. The first and second openings are each elongated and are sized to permit the entry of a gloved hand therein yet resist the entry of a toe of a conventional steel toed boot or shoe that is manufactured according to Standard Z41 of the American National Standards Institute.
