Abstract
A mounting structure for a screen frame and/or a top cover to a vibratory frame of a screening machine requires only an initial one time adjustment and includes a pair of elastomeric restraints each including a compressible bumpers on a head-end of the screen frame or top cover and a pair of compressible rollers on a foot-end of the screen frame or top cover. The screening machine mounting structure accounts for the manufacturing tolerances between the screen frame or top cover and the vibratory box frame to provide a snug fit. The rollers allow for easy screen frame or top cover installation and removal and prevent metal-to-metal contact between the respective components which generates wear and noise during operation. Further, the mounting structure according to this invention can be retrofittable into existing screening machines as well as being original equipment and is useful for securing other components of the screening machine in addition to the screen frame and top cover.
