DEFINITION

Classification: 38/41

(under subclass 40) Devices wherein the platen is moved in two sharply delimited stages. One stage may be personally operated. Both stages may be motor operated, either by a pair of fluid motors operating successively or by a single fluid motor subjected to two different pressures or operating through a linkage which abruptly changes its leverage. The subclass does not include patents wherein the change in leverage is effected solely by reason of the contour of a cam.
