摘要：A snow drag in which the snow moving member is a sector of a pneumatic semi-resilient tire carcass extending through an arc of about 120°. A transverse sectionthrough the tire carcass is arcuate in shape with the outer edge being used as a snowdrag and the interior of the carcass functioning as a scoop for gathering the snow. Ahandle is rigidly secured to the center of the inner edge of the tire carcass sector andradially extending and arcuate reinforcing members are mounted on the exterior andinterior arcuate surfaces. These members are arranged in pairs with rivets interconnectingthe two members of each pair and extending through the tire carcass. This arrangementpermits the tire carcass to have a certain amount of resiliency while still retaining itsoverall general shape.
