  • Patent number: 4332158
    Abstract: A manually held device for measuring and indicating slump of flowing concrete material being discharged from a concrete mixer along a discharge chute in which a torque responsive member is contained within a manually held housing, a sensing assembly is connected to the torque responsive member and extends beyond the housing for at least partial immersion in concrete material flowing in a discharge chute. The sensing assembly includes diametrically opposite sensing members of different size adapted to turn about the axis of the torque responsive member to produce torque forces of different magnitude and direction, the resultant of said forces being transmitted to the torque responsive member, and indicating means on said housing and associated with the sensing assembly for showing measurement of the slump or consistency of the flowing concrete material.
