ABSTRACT:
A panel placing device has a carriage frame on which are pivoted links connected pivotally to a panel frame adapted to support a panel. There are springs connected to the links and to the panel frame for urging the panel frame in one rotational direction. A lever pivoted on the carriage frame has a one way abutment with the panel frame and is moved by a tackle connected to the lever and to a rotary drum on the carriage frame. The lever is also pivoted on the carriage frame to swing aside. The drum is rotatable by a crank and is under control of a one way brake and a one way clutch.
