Description: |
| Abstract:
My invention relates to machines for cutting internal gears, and more particularly for gears of comparatively small diameter and long face and the object of my invention is to provide a mechanism for cutting internal gears, which can be readily applied to any ordinary iron planer and be simple in construction and mode of operation.
Claim:
The combination, with a reciprocating table, a supporting-bed, and stands for carrying the work, of a cutter-bar supported at one end from the bed on a bearing adjustable in the direction of the length of the cutter-bar, and at the other end on a bearing carried by a toolhead movable in a direction at right angles to the length of the cutter-bar, and a cutting-tool carried by the bar. |
