ABSTRACT:
A safety device is disclosed for locking in an upright position a lever arm having a rotatable base with projecting stop portions. The safety device comprises a body having means at one end for pivotally mounting the body near the base of the lever arm. The body also has a recess located centrally on one side of the body and adapted to fit beneath the base of the lever arm. On each side of the recess are a pair of upwardly projecting fingers adapted to engage the stop portions of the rotatable base portion of the lever arm to lock the lever arm in its upright position. The device can be easily moved into place to maintain the lever arm in its inoperative or neutral position to prevent inadvertent movement of the lever arm in either direction.
