Abstract
A device to permit manual adjustment of the track or path of a conveyor belt (,) while providing constant, predetermined belt tension. A removable conveyor roller (,) is supported by a pivotable yoke (,), which is pivoted about a shaft (,) from a nonoperational position of no belt tension, at which point cleaning and regular maintenance take place, to the operating position of full belt tension. Conveyor belt tension is provided by at least one spring (,), the spring force increasing with deflection during the pivoting motion of the roller yoke (,) into the normal operating position. The spring force resists the motion of a pivoting plate (,) to slide in a plane relative to the fixed conveyor bed (,) along an adjustable axis. Force is transmitted through the pivoting shaft (,) to the yoke (,) which creates tension in the conveyor belt (,) without exceeding the load limitations of the conveyor belt (,) or the roller shaft (,) bearings. An adjustable axis between a sliding plate (,) and a pivotable plate (,) can be rotated about a spindle (,) on the conveyor bed (,) to control the orientation of the conveyor roller (,).
