Abstract: A transfer mechanism for transferring articles one by one from one position to another position, particularly for use with a forging press having a plurality of molds arranged in series to successively transfer blanks from a receiving position to the mold of the first step and then to the mold of the second step and so on. The transfer mechanism comprising a pair of parallel feed bars provided on their opposing surfaces with plural pairs of clamping jaws and three separate sets of hydraulic cylinders for moving the feed bars in three orthogonal directions, respectively, and cam-operated hydraulic pumps operated with cams mounted in different phases on a drive shaft rotated in timed relation with the forging press, each cam-operated hydraulic pump being hydraulically connected to each hydraulic cylinder so that the feed bars effect cyclic movement to clamp, lift up, carry ahead, lift down, and unclamp blanks and to return to an original position.

Abstract: A wave dissipating wall is formed of a plurality of wave chambers comprising a plurality of horizontal plates and vertical partition walls opening toward the direction from which waves come in. The ends of the walls dividing the chambers are wider than the remaining parts of the walls and the front walls comprise semi-circular curved surfaces extending toward the direction from which the waves come in order to introduce the waves into the chamber having a wider width than the entrance formed between the respective front walls and to let the waves circulate within the chamber by the energy of the waves, thereby increasing the friction resistance between the waves and the walls as much as possible and achieving an efficient diminishing of the wave energy.
