Abstract
A jointed hand brake release handle for a railway car hand brake mechanism, having a lever arm with an inner end attachable to a rotatable hand brake release post of a hand brake mechanism, and an extension arm pivotally attached to the outer end of the lever arm and adapted for pivotal movement such that a contact face on the inner end of the lever arm can be brought into contact with a contact face on the outer end of the lever arm, and such that continued pivotal movement of the extension arm will cause rotational movement of the lever arm and rotation of the hand brake release post.
