ABSTRACT:
A brake hanger comprises upper and lower U-shaped lugs of substantially rigid material spaced from each other by a pair of laterally spaced leaf springs which are rigidly secured to the lugs respectively at their opposite ends. The upper lug is adapted to be journaled on a fixed pivot pin secured to the frame of a railway truck, and the lower lug is adapted for journaling connections to a plurality of elements, including a connection to a brake head and a connection to a brake cylinder. The lugs provide rigidity for alignment of their pivots, while the spring rated connection between the plugs provides for substantial lateral movement of the lower lug relative to the upper lug without deforming the parts of the hanger beyond their elastic limits, and without substantially altering braking performance by maintaining side thrust of a wheel flange against a brake shoe carried by the hanger at a minimum.
