DEFINITION

Classification: 188/264

Devices for cooling or lubricating brake-shoes or brake wheels or drums.

(1) Note. This subclass takes such wheel structure as may be necessary to the functioning and/or support of devices which, by disclosure, are intended to facilitate the removal of brake-generated heat from a braked wheel or to prevent transmission of such heat from a brake part or parts to other portions of the wheel. This is so, regardless of whether any brake structure is claimed. For example, patents drawn to ventilating wheel covers for the above stated purpose, or to the combination of such covers with their respective wheels, are classified here.
