ABSTRACT:
A drawdown hopper isolation system having a series of isolators supporting the hopper in spaced relation from a support surface. Each of the isolators is comprised, in preferred form, of a rubber block having an axial bore therethrough, a series of parallel nylon fabric lays being axially spaced one from another within the block. The nylon fabric lays are rotationally oriented in random fashion, relative to the axis of the block, so as to insure relatively even lateral deflection of the isolator in response to vibration of the hopper. A stud fixed to the hopper extends into one end of the isolator's bore, and a stud fixed to the hopper support surface extends into the other end of the isolator's bore, thereby locating the hopper in a desired position on the support surface.
