Abstract
547,549. Cupping. JOHANSEN, E. K. Aug. 26, 941, No. 10871. [Class 83 (iv)] In a drawing press, the inner and outer sliding press members are actuated by connections from a single crank so constructed and arranged as to provide a dwell in the movement of one member to hold the work while an operation is performed upon the work by the other member. The crank comprises a pair of spaced gears 37, 40, Fig. 4, rotatable upon supporting shafts 38, 41 and connected by a crank pin 48 linked at 50 to a plunger 21 carrying the inner slidable press member. The outer press member is carried by plungers 22 connected by links 64 to members 62, rockably mounted on the shafts 38, 41 and connected by links 67, Fig. 6, to arms 56 on a rock shaft 55 having a further arm 57, Fig. 4, connected by a link 53 to the crank pin 48. The actuating mechanism for the press members is duplicated at the other side of the press as shown in Fig. 6, the two pairs of crank gears being actuated in synchronism by interconnected gears driven from the main driving shaft 25.
