Adjustably mounted on a lower portion of the carriage member is a toe-like member which normally assumes a pendent position projecting from the carriage member. The toe-like member has an exposed surface portion in an aligned coplanar relation with the carriage member cam surface and forms an extension thereof when the toe-like member assumes its pendent position. The toe-like member is moveable from its normal pendent position by a reactive force exerted thereon by the roadway when the carriage member moves vert…
