Claim 29:
30. The system of claim 26, wherein a second plurality of apertures are provided on the second side edge of the support member, each of the second plurality of apertures including at least one compression surface, wherein the vibratory screening machine further comprises a second plurality of compression assemblies mounted on a second side of the screen receiving bed, wherein when each of the compression pistons of the first plurality of compression assemblies move from the retracted position to the extended position, the at least one compression surface of each of the second plurality of apertures of the support member are pushed into engagement with corresponding ones of the second plurality of compression assemblies, and wherein the compressive forces applied to the at least one compression surface of the first and second plurality of apertures are sufficient to hold the screen assembly against the screen receiving bed of the vibratory screening machine while the screen assembly is subjected to vibratory forces that apply between 3 G and 9 G of acceleration to the screen assembly.
