DEFINITION

Classification: 152/266

The interior surface of the integral enclosure about the radial coil springs presents an arcuate cross-section throughout, except that there may be some departure from the arcuate in providing wheel securing means adjacent the rim.

(1) Note. For similar devices without the wheel encircling band, having unconnected shoes between the springs and enclosure whether the shoes are overlapping or not, see this class, subclasses 298 and 299.
