Description: |
| This, my invention, consists in a novel arrangement of devices with and for operating a sliding punch or punch-stock, including a lever, pinion, toothed sector, and pitman, eccentrically pivoted at its one end to the .latter, and to the punch-stock at its opposite end, whereby a most advantageous application of power is obtained, and by it I am enabled, for a given stroke, to work closer to the centre of the sector, and use a shorter lever than where a cam or eccentric is used to operate the punch-stock. |
