Abstract
Abstract In a vibrating device in which vibration is provided in one direction by at least a pair of side-by-side motors having shafts rotating in opposite directions and with eccentric weights on the shafts, a timing belt engaging sprockets on the motor shafts to insure synchronization of the motors. In one form the belt is in a figure 8 configuration and in this form, separator means to reduce friction at the crossover location of the belt is provided.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
90 words
In a vibrating device having at least a pair of side-by-side motors with eccentric weights attached to the ends of each motor shaft and with the motor shafts rotating in opposite directions to provide vibratory motion in one direction, the improvement comprising a toothed sprocket connected to each motor shaft, a timing belt engaging said sprockets in a figure-8 configuration to insure synchronization of the rotating motor shafts, and means separating said belt at the cross-over location to reduce frictional contact between the portions of said belt at said location.
Claim 2
Dependent Claim
