Abstract
818,977. Core-making machines. MASCHINENUND WERKZEUGFABRIK KABEL VOGEL-SCHEMMANN A.G. Nov. 18, 1957 [Nov. 28, 1956], No. 35828/57. Class 83 (1). In a core-blowing machine control means such as a push-button &c. for actuation of a compressed-air feed valve controlling two or more operating steps is disposed on each side of the machine. One operator brings a core-box into position for blowing, and a valve is positioned so as to actuate a pneumatic piston 5 to close the sand container 1 by a slide 3. Movement of the slide also opens a safety valve 8, so that actuation of push-button 11<SP>1</SP> by the operator will cause pressure air to travel via line 9, valve 8, line 91, valve 11, line 16, non-return valve 17 and line 17<SP>1</SP>, to open the main-feed valve 14, thereby causing the operations of the machine, e.g. box-clamping table-lifting, blowing &c., to take place automatically. Thereafter the blown box is removed, and a second operator may insert his empty core-box into the machine and initiate the operating sequence by actuation of the push-button 10<SP>1</SP> on his side of the machine.
