  • Adjustable clamp and force level indicator for screening machine cover
    Patent number: 6073979
    Abstract: A clamp for securing a removable cover on a screening machine is an over-center mechanical clamp which includes two distinct clamping force adjustment mechanisms. A first clamping force adjustment mechanism includes a plurality of clamping positions on a support bracket mounted on the cover. The clamp handle assembly is selectively positioned in one of the clamping positions on the support bracket to provide incrementally different clamping force levels. Additionally, irrespective of the clamping position, rotation of a threaded rod of the clamp adjusts the clamping force. A force level indicator is provided on the clamp to indicate the clamping force produced by the clamp.
