Abstract
497,428. Flanging plates. SCHULER AKT.-GES., L.. and WIEST, M. June 16, 1937, No. 16786. [Class 83 (iv)] In means for flanging holes in plates a clamping member forms also a flanging die and houses means for locating the workpiece. A holed plate is positioned on a bed b and a clamp e on a yoke d is lowered by a hand wheel f. The clamp e and the bed b carry exchangeable plates c with holes of different size. A locating plug i resiliently mounted in the yoke, enters the hole in and, positions the plate. Rotary movement of a hand lever z raises a bearing w on a shaft m, rotated from a pulley n, and adjustably carrying flanging rollers v. In operation, the rollers first move the plug i out of the way and then co-operate with the clamp e to effect the flanging.
