  • Patent number: 4219133
    Abstract: The storage level of ore, supplied by an overhead loader to a bin or pile in the form of large, dense, hard fragments, up to a foot or more in diameter, is measured and controlled by repetitively lowering a line carrying a weight, having a mass at least as great as the largest ore fragments, from above the stored mass to the surface of the stored mass and measuring the distance traveled by the weight. Feed of ore is automatically stopped when maximum allowable level of stored mass is detected. Measurement of ore level is accomplished by counting, during the lowering of the weight, the pulses generated by a pulse generator operated by the turning of a winch upon which the line is reeled. The contact of the lowered weight with the stored ore mass is detected by the slowing of the rate of pulse generation as the weight ceases falling under the influence of gravity and the winch therefore ceases turning.
