943,988. Casting machines. GLOBE-UNION Inc. Jan. 11, 1962, No. 1086/62. Heading B3F. In a machine incorporating two separate casting units A and B, apparatus for each of the pouring moulds 26 comprises an L-shaped reservoir 30 with a molten metal intake section 32 and a pouring section 34. The temperature of the molten metal is thermostatically controlled by electrical heating elements 40 connected to terminal boxes 42. The level of the molten metal is maintained and controlled by a slidable weir 44 and a fixed partition 46 at the end of the intake section 32. Molten metal is poured from the reservoir by the action of a reciprocating displacement member 54 actuated by way of a cam and lever from a drive shaft 16. Baffles 78 depending from cover 70 on opposite sides of the member 54 serve to localize the level changes caused by the action of the member. The baffle nearest outlet 76 serves also to prevent surface impurities in the metal being passed into the mould. The casting operation may be started or stopped by starting or stopping the action of the member 54. The moulds 26 include a stationary part 80 and a movable part 82 removably mounted on rods 84. Said mould may be opened or closed by sliding part 82 on rods 84 by means of bracket 86 having removable arms 88. The action of the pouring apparatus and mould opening and closing means are synchronized so that the pouring starts at the instant the mould closes. The operation of the various parts of the apparatus is effected by cams and linkages from shafts 16 and 18 and may also incorporate pneumatic clutches for controlling independently the parts required. The completed casting is discharged from the mould and carried by carrier arms 110 to a conveyer and deposited thereon for removal from the machine, the castings being watercooled whilst on the conveyer.
