Abstract
764,990. Core-making machines. SUTTER PRODUCTS CO. Dec. 6, 1954 [Dec. 7, 1953], No. 35293/54. Class 83 (1). [Also in Group XXX] A machine for making sand-cores comprises open-topped sand-carrying chambers 56, 57 having perforated bottoms 66, 67, sand-dispensing hoppers 35, 36, fluid-pressure conduits 14 leading to a blower-chamber 17 between the hoppers, means for reciprocating the sand chambers to position one below the blower chamber while the other is below a hopper, and a vertically movable table 74 to support a corebox 62 beneath the blower chamber. Each sand chamber carries a projecting plate 60, 61 which closes the appropriate hopper as the chamber moves under the blower. The table 74 carries rollers 75 to assist in removing completed core-boxes 62 and is moved vertically by an air-operated piston. When the core-box has been raised to push the chamber against the lower plate 20 of the blower, an exhaust-line 76 is opened and pressure in a chamber 16 forces up a valve 27 supported by spring-plates 31, 32. Air then enters the chamber 17 to blow the sand into the box. The sand chambers may contain different mixes.
