The upper headed'ends Figure 1 is a vertical section of a pot of the members 10 are likewise secured embodying my inve tion, and also showing against lateral disengagement by the straps a portion of a pot-lifting mechanism in 18. Two of the straps 10 are preferably arside elevation, and Fig. 2 is an elevation, ranged at each side of the pot, one at eac partly in section, at right angles to Fig. 1. side of the lifting lugs 9, and these lifting My invention has relation to certain new lugs are preferably integral with the lugs and useful improvements in pots for hol 13, in which the headed upper ends of the ing material of various kinds, and which straps are seated. These straps or tie memare required to be lifted, and in which the bers extend across the portion of -the pot material composing the pot is not of such where the cracks are most likely to occur, character as .to make its handling safe. and serve to transfer the lifting strain to is more particularly useful in connection the lower portion of the pot and below'the with pots for holding cinder from open point where cracks usually develop.
