CURBING MACHINE WITH HOPPER DASHER AND ELIPTICAL COMPACTION
First Claim
1. A manually maneuverable curb forming extruder propelled apparatus for concrete, cementitious and other similar plastic building materials comprising:
- a. a chassis frame with speed reduction unit with walls defining a feed hopper with a top opening 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. a dasher with frame and cross-bar sized to fit and pivot within the hopper pivotally affixed to the top opening to pivot within the hopper to break up bridged building materials,c. 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,d. 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;
e. 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, andf. a drive motor with speed reducer associated with the compacting member to reciprocate and orbitally move the compacting member and pivot the dasher.

Abstract
A concrete curb forming and extruding apparatus with wheel adjustment locks, and an adjustable slip form system shaping cementitious material into a continuous curb forced there through by an extruder which receives materials stored in a hopper with dasher. The extruder has a rotary trowel compacting member which continually forces material from the hopper into compressed concrete passing through an adjustable slip form to fill the same and form differing shaped continuous curbing underneath fences or against vertical surfaces or conventional curbing, depending upon the slip form setting.
