DEFINITION

Classification: 188/234

Includes patents for methods or devices for fastening wearing-shoes to the holder.

(1) Note. In the railway type of brake the shoe is attached to a holder called the "head", and this is attached to the beam. In the wagon type of brakes, where the wearing-shoe is attached directly to the brake-beam, the patents will be found in this class, subclass 220 or 221 above.
