ABSTRACT:
An apparatus for use in a so-called knock-out or shake-out system for foundries comprises a beam which may be resiliently suspended by a stirrup and bellows. A pair of tubular frames depend from the ends of the beam and a pair of rectangular clamp frames are vertically slidable in the tubular frames. A mold box comprising a pair of box-frames and containing a metal casting in a sand mold is located between the two pairs of frames. Two sets of bellows one associated with each clamp frame are inflated to raise the clamp frames and clamp the box between the lower crosspiece of these frames and some other part of the structure such as the lower cross-piece of the tubular frames. The mold is vibrated by vibrators so that the sand and casting are shaken out of the box.
