Wheel.
Patent for a new and improved wheel. This design, when "traversing soft and marshy soil[,] the ribs or lugs engage in the surface in the ordinary way; but in passing over hard or stony soil the flange bears on the surface and prevents jarring. The ribs and the flange are flush with each other . . . and this height may be considerably more than that of the ordinary ribs . . . for the reason that the said height does not affect the regularity of motion of the wheel in passing over hard soil. The advantage in tapering the ribs or lugs and the inner side of the flange is to prevent earth from clogging therein" (lines 51-53).
