DEFINITION

Classification: 152/263

(under subclass 262) Devices in which the flexible wheel encircling band, the band-supporting radial coil springs, and all radially reciprocating elements except the tread are completely enclosed in an enclosure common to all. This enclosure may consist of a plurality of elements.

(1) Note. For similar devices without the wheel encircling band, having unconnected shoes between the springs and enclosure, whether the shoes are overlapped or not, see this class, subclass 293.
