Abstract:
A wedge lock system for securing a screen panel to the deck of the basket of a vibrating screening apparatus. A retractable plate is extended through an inclined first access passage which is formed in a side wall of the basket. A wedge is driven between the projecting plate and a screen panel positioned on the deck, thereby securing the screen panel to the deck. When the plate is moved to its retracted position, a screen panel may be raised or lowered vertically, without obstruction.
