Gyratory compactor with mold specimen extruder

A gyratory compaction apparatus for compacting a material held in a mold as the mold is gyrated, the apparatus comprising:

• a frame,
• a mold supporting surface upon the frame,
• a mold for receiving material to be compacted,
• a power driven compaction ram for compacting material in the mold by insertion of the ram into the mold,
• a mold gyrator for gyrating the mold as the compaction ram is inserted into the mold, and
• a material extractor for extracting compacted material from the mold, the material extractor having a mold supporting surface and a vertically oriented rod powered to rise vertically from the mold supporting surface of the frame to extract material from a mold.

A gyratory compactor apparatus for subjecting a material to forces, comprising:

• a frame having a first mold supporting surface, a mold gyrating assembly, a ram and a ram drive assembly,
• said mold having a mold cavity for receiving a quantity of said material,
• said mold further having an open top and a closed bottom,
• a ram supported by said frame and insertable into said mold cavity through said open top of said mold to compact said material in said mold, and
• a mold gyrating assembly in contact with said mold and operative to gyrate a vertical axis of said mold relative to a vertical axis of said ram as said ram is inserted and driven into said mold cavity, and
• a mold material extractor having a second mold supporting surface in a same horizontal plane with the first mold supporting surface, mold positioning brackets attached to the second mold supporting surface, and a vertically oriented extractor rod operative to rise from said second mold supporting surface into said mold to extract material from said mold.

A gyratory compactor apparatus for compacting a specimen of material while said specimen is gyrated, said apparatus comprising, in combination,

• a mold for holding said specimen,
• a mold support structure for supporting said mold,
• a compacting ram positioned and driven for insertion into said mold to compact said specimen within said mold,
• a mold gyrating assembly in contact with said mold and powered to gyrate said mold while said compacting ram is inserted and driven into said mold and,
• a mold extractor for extracting material from said mold.

A material compaction apparatus comprising:

• a mold for receiving a material to be compacted,
• a mold supporting frame,
• a compaction ram driving assembly connected to a compaction ram positioned for insertion into the mold,
• a mold gyrating mechanism in contact with the mold,
• and a mold material extruder assembly for removing compacted material from the mold, the extruder assembly comprising a mold supporting surface in a common plane on which the mold is supported by the mold supporting frame, a mold bracket on the mold supporting surface which positions and secures the mold over a vertically oriented extrusion ram powered to rise from the mold supporting surface into the mold to extrude material from the mold.

A combined gyratory compactor and mold extruder assembly comprising:

• a frame which supports a mold gyration assembly and a first mold supporting surface,
• a mold for holding material to be compacted,
• a mold gyrator and a compaction ram,
• a second mold supporting surface, and
• a mold specimen extruder having an extrusion rod positioned and powered to rise from the second mold supporting surface.
