Ordinary split patterns ofeither wood or metal are clieaply appliedto flat plates in this machine, six sets offour to eight pieces of split patterns hav-ing been fitted to plates by one man in asingle day. Fig. I shows the machine ready to re-ceive the flask, the patterns being for molding. Fig. 2 shows the ma-chine after the patterns have been drawnand flask lifted off. Briefly, the operation of the machineis as follows: The ramming head shownthrown back at the top of the machine isdrawn forward into a vertical position,alter flask has been placed and filled withsand. The three-way cock shown at thethe extreme right is then quickly opened,admitting compressed air at 70 to 80 compression valve, shown at the left sideof top of machine, thus admitting com-pressed air to a pneumatic vibratin
