A CONVERTIBLE ROAD GRADER AND SNOW PLOW<br />

This dual purpose machine is the recent offering of a Minnesota inventor, and is now being used by<br />

the city of Minneapolis. The diagonally arranged scraper or plow blade may be raised or lowered by<br />

the hand levers. It also may be tilted to a slanting position for working on the side of an arched<br />

roadway. The improved supporting frame by which the scraper is pivotallv supported in proper<br />

position when the machine frame is tilted prevents breakage of the parts.
