Abstract
Abstract A support means adapted for use with snowmobiles is provided which comprises two laterally aligned support shafts depending from one end of the snowmobile; each of the support shafts has a bracket formed on the lower end thereof. Axles extend horizontally from the lower ends and are adapted to secure either skis or wheels thereon. Resilient plugs are affixed to the brackets, the lower ends of which are disposed proximate the top surfaces of the skis. The resilient plugs prevent the skis from rotating more than a present distance and absorb some of the initial shock in rough terrain.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
236 words
A support means for a snowmobile-type vehicle having a front end and a rear end, a drivable endless track for motive power and means for driving the track; the support means comprising: two supports shafts depending from proximate one of the ends of the snowmobile, shafts being transversely aligned; bracket means affixed proximate the lower ends of each of said support shafts with the ends thereof extending backwardly and forwardly of the lower ends of said support shaft; axle means horizontally affixed to each of said support shafts, wherein each of said axle means is a substantially cylindrical shaft having two ends and is secured proximate one of said ends to said support shaft and extends outwardly therefrom, the other of said ends having means formed thereon for rotatably securing either a wheel or a ski thereon; two skis having mounting members secured thereto intermediate the ends thereof, said mounting members each having a hole formed therethrough transversely of the ski for rotatably and demountably securing said skis on said shafts; and resilient means affixed to and depending from each of said bracket means wherein each said resilient means is at least two resilient plugs, one of said plugs being disposed forwardly of said support shaft lower end and the second of said plugs being disposed backwardly of said support shaft lower end, whereby said skis are rotatable a preset distance about their respective said shaft.
