  • Folding motor vehicle immobilizer and chase inhibitor
    Patent number: 6749362
    Abstract: A folding motor vehicle immobilizer and chase inhibitor to surround both the front and rear of the tire of a motor vehicle that has been stopped for investigation by law enforcement officers to prevent the vehicle and its operator from fleeing the scene of the stop so as to avoid the risks inherent with a high speed chase. The chase inhibitor includes a frontal member that is located against the outside of the tire to be surrounded and a pair of outwardly projecting spike supports that are pivotally connected to opposite ends of the frontal member. Each of the spike supports carries a set of sharp hollow spikes that are aimed at and adapted to puncture and deflate the tire should the vehicle drive off in either the forward or the reverse direction.

  • Sheet cutting die press
    Patent number: 5255587
    Abstract: The sheet cutting die press includes a handle fixed to a cylindrical shaft, the longitudinal axes of which is off-set from the longitudinal axes of stub axles at either end of the shaft. Thus, as the handle is moved causing the shaft to rotate, it applies pressure through a pair of bearings to a pair of pillow blocks which in turn rests on the top surface of a top platen. A cover over the cylindrical shaft is fixed to the pillow blocks so that, as the handle is moved to a position to retract the platen, the pillow blocks are lifted by the cover.
