Abstract
531,791. Moulding-machines. OYSTER, E. F. Aug. 2, 1939, No. 22385. [Class 83 (i)] Sand is consolidated in a flask 36 by horizontal vibration in all directions caused by the rotation of an unbalanced mass 34, Fig. 3, preferably rotated by an air turbine 28. The sand may, at the same time or subsequently, be pressed against a swinging head 16 by a fluid operated plunger 12 having a spring-mounted table 22, carrying the turbine 28, on which the pattern plate 25 and flask rest. The plunger has stops 18 to limit the compression of the springs 23.
