Abstract

7446. Cotton, E. W. March 25. Grinding interfitting parts together.-A device for grinding the valves of internalcombustion engines upon their seats comprises a single plug B to screw into the cylinder hole opposite the valve, and a spindle C rotatable and movable endways in the p l u g and formed with a flattened l o w e r end adapted to engage a groove in the valve head. A cranked handle D or ratchet device is provided for turning the spindle, and a spring A is put on the valve stem to lift the valve slightly when the grinding pressure is removed and allow abrading-material to fall between the valve and its seating.
