To operate, the elevator operator would hold the crank in place to engage the lift. It was referred to as a "Dead man" control due to the need for the operator to be attentive and in full control to maintain elevator position!
Controls read "Emergency Stop", "Emergency Operation", "Light Switch" and "Stop, Start" around a Yale lock.
This piece was salvaged from the Public Service Building of Nashville, Tennessee, est (1929).
