Aggregate extruder
First Claim
1. A self-propelled extruder for depositing a multi-layer aggregate bed over a defined surface, said extruder comprising:
- (a) a dispenser frame having a first means for depositing a first layer of aggregate on said defined surface, a second means, adjacent said first deposition means, for depositing a second layer of aggregate on top of said first layer of aggregate, and a third means, adjacent said second deposition means, for depositing a third layer of aggregate on top of said second layer of aggregate;
(b) means, attached to said dispenser frame, for self propelling the dispenser frame over said defined surface, wherein said self propulsion means includes a wheel means and a ram means, mounted on said dispenser frame, for engagement with a support, for movement of the extruder along a desired path in a direction opposite the extension of said ram means; and
,(c) means, attached to said dispenser frame and extending rearward thereof, for providing side vertical support for the multi-layered aggregate deposited.

Abstract
This invention is an aggregate extruder for the deposition of a multi-layered aggregate bed having layers of differing aggregate material. The extruder is divided into three sections transversely disposed over a defined surface, each of the sections contains a different aggregate material. A front grading baffle is mounted behind a front panel extending intermediate side panels forming the front dispensing section. A second grading baffle is mounted between the first and rear grading baffles forming the middle dispensing section, behind the front dispensing section, and a rear dispensing section. The extruder is self-propelled by a hydraulically operated ram mounted to each side panel. A panel is mounted to the rear of each side panel of the hopper and extends rearward thereof to define channel within which aggregate is maintained as the hopper moves along the surface. When the ram is activated it extends rearward for engagement with a form, and pushes the extruder along the defined surface. The aggregate material from each dispensing section is deposited on the ground. Each grading baffle grades the layer of aggregate deposited immediately forward the grading baffle to a preselected level.
