Abstract

335,381. Grocholl, K., and Weber, H. Oct. 5, 1928, [Convention date]. Moulding-machines.-The velocity of projection of a centrifugal sand-projecting machine is varied by feeding the sand to blades d of the rotor c at different distances from the discharge opening p. The sand is fed by a funnel j to a circular chamber i in which rotate blades e carried by the rotor' c. The 'chamber has an opening q and can be circularly adjusted by a toothed annulus f engaged by a pinion rotated by a hand wheel h. The casing a has handles n and a renewable portion b and is suspended by a ball joint m or a sliding support.
