ABSTRACT:
A shuttle having the same shape as a mold cavity has a slidably removable bottom so that material distributed in the shuttle may be dropped into the mold by removing the slidable bottom with a series of baffles positioned in the mold serving to hold the material in the shuttle in position so it will not be moved out of position as the slidable bottom is removed.
