Abstract
Abstract An auxiliary wheel structure for attachment to a regular vehicle wheel which has angularly spaced apart wheel lugs, including an auxiliary wheel rim, an arcuate track fixedly attached to the auxiliary wheel rim, attaching brackets slidably mounted on the arcuate track for adjustment therealong to positions in alignment with the lugs on the regular wheel, and connecting rods between the brackets and the wheel lugs to mount the auxiliary wheel structure to the regular wheel in side-by-side relationship. The attaching brackets embrace the track on the auxiliary wheel rim to permit sliding adjustment therealong but retaining means are provided to prevent removal of the brackets from the track. Lock members are provided to maintain the attaching brackets on the track in any of the positions of adjustment.
