Abstract
997,564. Machinery guards. LEIPZIGER EISEN-UND STAHLWERKE VEB. April 15, 1964, No. 15626/64. Heading F2J. In a moulding machine of the type having a blowing head 2 and a vertically movable table 7 to support a core box 8, a device is provided to protect the machine operator against flying sand during the blowing operation. The device comprises a U-shaped shield 3 movable about pivots 1, and having pneumatic piston and cylinder assemblies 4 actuated by control means (not shown) to effect raising and lowering of the shield 3. When the machine is started, the screen is automatically lowered into position at the level of contact of the bore box 8 with the head 2. The blowing operation is then effected and the shield returned to its inoperative position. Stops 5 are provided to limit the movement of the shield.
