1. A manually maneuverable curb forming extruder propelled apparatus for concrete, cementitious and other similar plastic building materials comprising:

  • a. a chassis frame with walls defining a feed hopper structured to receive, hold, and gravity feed building materials into a compaction chamber having a front and rear with a rear opening which directs building materials through the rear opening to propel the chassis frame forward,b. steering and castering wheels attached to the chassis frame via swinging arms which allow the wheels to be adjusted from side to side for manual steering of the apparatus,c. a reciprocating compacting member having a compacting surface orbitally mounted to the chassis frame such that the compacting surface moves in a reciprocating elliptical orbit within the compaction chamber to withdraw, drop and receive building materials from the bottom outlet of the hopper in a loading stroke, and to force and lift the building materials rearward into and through the rear opening of the compaction chamber in a compaction stroke;

    d. a removable slip form with open forward and rearward ends and an open bottom in communication with the compaction chamber rear opening to receive and sectionally form the building material into a continuous curb form, ande. a drive motor associated with the compacting member to reciprocate and orbitally move the compacting member.
