DEFINITION

Classification: 299/65

(under subclass 64) Apparatus in which the means to move or carry material is combined with a cutter that is described as forming a cut at the bottom of a block of material, such material being subsequently dislodged to be handled by the moving or carrying means.

(1) Note. A separate dislodging means does not necessarily have to be claimed for a patent to be included under this definition, as long as the cutter and conveyor are claimed and dislodging is described.
