Abstract
An accumulator conveyor is equipped with sensors which respond to article movement by pivoting about a vertical axis as the result of having a pair of laterally spaced wheels on opposite ends of a shaft with one wheel driven by the propelling member and the other by an article supporting roller. The first wheel is larger than the second wheel and is attached to the shaft while the second wheel is connected to the shaft by a one-way clutch. Pivotal movement of the sensor results from differentiation between the relative speeds of the wheels.
