Abstract

332,712. Grindal, M. June 3, 1929, [Convention date]. Moulding-machines have impacts applied to the flask while pressure is applied to the moulding material. A hammering device h, operated by fluid, is arranged in a hollow, fluid-operated plunger 1 adapted to press the moulding table b &c. against the usual adjustable plate 5. In a modification the table b and device h are stationary and the plate 5 is adjustable in and pressed down by a. fluid operated plunger 8, Fig. 2. In another modification the hammering device rests on an adjustable spring strong enough to keep the plunger thereof in contact with the table so that in operation the cylinder reciprocates and strikes the table b. The impacts are arrarged to commence before the pressure is applied.
