Abstract

Sand in a succession of mould boxes 3 is compacted by dropping a battery of rows of rammers 10 movably guided by cylindrical portions 9 in sleeves of a frame 5 suspended from a beam 12 lifted by a compressed air cylinder 15 and piston 16 to raise the rammers. Buffers 34 determine the bottom position of the frame and beam. The rammers 10 and their heads 8 may be of square or hexagonal section. The air cylinder 15 is fixed to a frame member 14 and air from its inlet groove 21 passes into the piston 16 (containing a space-resitrictor 18) through a piston groove 20 until this is cut off by the rising of the piston. A further cylinder groove 22 releases the air when cleared by the piston skirt to allow the piston 16, beam 12, frame 5 and rammers 10 to drop. The mould boxes 3 are advanced step-by-step by a conveyer 2, being filled by a hopper behind the machine and bevelled by a scraper (27) at the front.
