1 Claim. (01. 72- 72) This invention relates to a pillar for supportshort blocks engaging recesses in said short ing roofs of mines so that all the coal can be reblocks. Thus all the blocks are firmly locked moved from the mine without leaving portions together and there is no danger of the units slipto form supporting pillars, the general object of ping out of place.
