Abstract

Improved means for manually and controllably releasing elevator hoist brakes having brake shoes urgeable into locking position by brake springs, said apparatus comprising a support bar, a first arm mounted adjacent one end of said support bar and carrying first brake release means engageable with one end of said brake springs, a second arm located adjacent the opposite end of said support bar, a compound lever which is generally V-shaped having one elongated leg and one short leg with the short leg being pivotally mounted on said second arm, and a generally L-shaped member having a short leg pivotally mounted adjacent the free end of said second arm and having a long leg pivotally connected to the long leg of said lever, and second brake release means pivotally mounted adjacent the intersection of the legs of said L-shaped member and engageable with the opposite end of said brake springs so that movement of said lever will drive said brake release means toward each other to accomplish controlled movement of said brake against the urging of said springs.
