A machining waste metal recycling machine has an in-feed hopper. The hopper uses paired augers to move the waste metal through the hopper to a cutting and transporting auger. The hopper augers are powered independently from each other, and may be individually reversed or reversed as a group to clear jams. In the event a jam is not cleared through one or more reversal cycles, the remaining augers may be operated to clear the hopper, thereby avoiding the need for manual unloading. Within the hopper are one or more shear bars that are provided to sever bunches or bundles of machining waste and thereby clear tangles which might otherwise jam the augers. The cutting and transporting augers ultimately feed a reciprocating compactor having a movable gate with one or more grooves for controlled drainage of machining oil and other liquid, as the machining waste metal is compressed into pellets.

A method of and apparatus for controlling drainage/irrigation of a field includes laying out a network of drainage tiles, which typically may include a main line and a number of lateral lines, extending from higher elevations to lower elevations and exiting through a manually controlled main valve to a drainage ditch.

A series of level-responsive valves are incorporated in the main and lateral lines at selected elevations. Each level-responsive valve is normally open until the ambient water level reaches a predetermined level relative to the valve. When the manual valve is closed and a certain level of water is reached adjacent a level-responsive valve, it causes that level-responsive valve to close, thereby cutting off drainage of higher elevations. When it is desired to retain water at higher elevations in a field, the manual valve is closed permitting water to accumulate and be retained at higher elevations by closing the level-responsive valves in sequence at progressively higher elevations as the level of retained water rises, thereby causing a cascading or “terracing” of water stored at upper levels. When the manual valve is opened, the field drains normally. The level-responsive valve may be a flotation valve. A modification of a flotation type level-responsive valve includes an overflow tube which permits excessive water at higher placement elevations to bypass the closed level-responsive valves, thereby permitting the field to drain under conditions of excess water into a standpipe at the manual valve.
