ABSTRACT:
Apparatus for forming, compacting and finishing the top surface of concrete poured between a pair of removable longitudinally extending parallel opposed forms. The apparatus, which is self-propelled, travels along the tops of the forms. A heavy wooden vibrator member disposed at the forward end of the apparatus may be shaped so that concrete beneath the vibrator is formed and compacted to a depth which varies along transverse axes of the forms. The structural members of the apparatus may be interchanged or adjusted to adapt the apparatus for use with forms of arbitrary spacing. Simple adjustments may also be made to permit the apparatus to traverse forms of unequal height. Removable "skirts" enable use of the apparatus with relatively narrow forms supported above the grade on which the concrete segment is formed--the skirts serve as a "travelling form" to prevent poured concrete formed and compacted by the vibrator spilling beneath the forms.
