Abstract
262,850. Stoney, J., T. Sept. 14, 1925. Moulding - machines.- Sand is packed in a flask by substantially continuous vibration. In order to effect this the flask 39, filled with sand &c. and pressed down with a weight 41, is placed on a table 1 resting on a frame 4 and a series of rapid blows is applied to the table by an impact piece 15 and piston 16, Fig. 4, which reciprocates in a cylinder 9 when air is supplied through a pipe 28. The supply ports 26, 27 are covered alternately by pierced flanges 17, 19 and the exhaust ports, not shown, are opened to each end alternately by the flange 18 which covers them in the intermediate position of the piston. The downward blow is cushioned by a cup shaped piston 33 supported by oil &c. under pressure. If desired the table 1 may be held to the frame 4 by spring bolts adapted to allow some upward movement thereof.
