Description: |
| Evans Flexible Reamer Corp. was acquired in 1943 by Lempco Products, Inc., and renamed to Evans Reamer & Machine Co. This patent provides improvements to the valve-seat reamer of patent 1,827,510 to better enable its use on smaller sizes of valves, and also to allow the use of standard reamer spindles and to provide a more chip-resistant cutting edge. |
