A positioning mechanism is provided for angularly positioning the wheel about the upwardly extending axis and has a plurality of set screws spaced from and in a surrounding relationship to the upwardly extending axis and engaging the plate member of the bracket upon which the wheel is mounted. The wheel support also includes a frame affixed to and vertically movable on the base for positioning the height of the wheel and thereby the height of the base.
