Spring wheels ; dust-excluders; felloes or rims; hubs; spokes; tyres, non-elastic.-In the form shown in Figs. 1 and 2, the hub C has sockets D adapted to receive the screwed ends of metal tubes E, in which slide plungers G secured at their outer ends to the rim H, either by riveting or by transverse bolts I and distance-pieces K. Within the tubes are helical springs M, on which the inner ends of the plungers bear to give a resilient connection between the hub and rim. Dust-excluding caps L may be fitted on to the outer ends of the tubes. In the modification shown in Fig. 4, the hub C is formed in two similar halves, which are fixed together by transverse rivets P so as to secure the inner ends of curved springs 0 in recesses. The outer ends of the curved springs are riveted to a channel-shaped rim H, in which a wood or similar tyre R is secured by rivets S.
