1,134,952. Casting machines. E. BOSSIROY. 31 May, 1966 [31 May, 1965], No. 24128/66. Heading B3F. In a handling apparatus for foundries, pallets supporting a plurality of moulds are arranged on carriages 3 that move from a moulding station (1) (Fig. 2, not shown) along a first inclined rolling track through a casting station at a gantry 12, and through a gas extracting and cooling chamber 27 to a stripping station 32 where the empty carriages 3 are lowered to a second oppositely inclined rolling track so that they move back, by gravitational force, to a hoist 10 near the moulding station. At the hoist 10 the carriage 3 is raised level with the first rolling track ready to receive another pallet loaded at the moulding station. The gantry 12, which can be moved along the apparatus by jacks 17, includes jackets 13 and weighting plates 14 and their lowering and releasing means, and a mono-rail 16 along which the casting ladle is moved in filling the moulds. At the stripping station a rocking platform (30) (Fig. 6, not shown) tips the cast articles and moulds on to a grid so that the sand of the mould falls through and on to a conveyer belt 33. The same rocker platform then lowers the carriage 3 on to the second rolling track. The carriages 3 are restrained in their movement on the first rolling track by elements on a circulating chain and on the second rolling track by a pneumatic brake.
