ABSTRACT:
This invention relates to a vibrating table where a rotary motion vibrator is used to provide vertical oscillations. In this table top arrangement the vibrator is secured to a frame or lower plate member preferably at or about its midpoint. This lower frame member is conventionally supported by a support base through vibration isolators such as coil springs provided at its corners. To at least two edges of this lower frame member are secured transfer pads which also are secured to the like edges of and carry the upper table top a spaced distance above the lower frame. The resulting vertical motion and frequency are equal or substantially equal at all portions of the table top and there is an absence of "dead spots." Conventional table tops of vibrating tables to which the vibrator is directly secured have a dead spot or spots and the amplitude is unequal causing the material or product thereon to walk or move to one side. Where the "dead spots" occur on conventional tables the material is neither moved or vibrated.
