Claim:
A wheeled carriage for engaging and supporting an appliance having an elongated shaft, comprising: an axle having a rotational axis, a first wheel mounted to said axle in a manner enabling rotation about said rotational axis, and a second wheel mounted to said axle in a manner enabling rotation about said rotational axis; a clamp mounted to said axle and disposed to remain in a constant position when said first wheel and said second wheel rotate about said rotational axis, and disposed to receive and retain an elongated shaft of an appliance releasably to said wheeled carriage, said clamp adapted to grasp said elongated shaft of said appliance only at a single region proximate a midpoint along a length of said shaft, said clamp including a first closing member, a second closing member bearing an eye disposed to adjustably engage said first closing member, and an over-center arrangement disposed to draw said eye into engagement with said first closing member, thereby securing said clamp in a closed position, wherein said over-center arrangement includes a lever pivotally mounted on said clamp at a location such that when said lever is pivoted, said eye is drawn into increasingly tight engagement with said first closing member; and an orientation adjuster disposed to selectively position said clamp in different orientations relative to said axle.
