| DEVICE OF A SECOND TYPE CAN BE ATTACHED TO THE CARRIAGE FOR EACH WORK STATION OR FOR ONE OR MORE SELECTED WORK STATIONS IN ADDITION TO OR AS A SUBSTITUTE FOR A TRANSFER DEVICE OF THE FIRST TYPE. EACH TRANSFER DEVICE OF THE SECOND TYPE HAS A PAIR OF JAWS WHICH CAN BE MOVED BETWEEN OPEN AND CLOSED POSITIONS BY A ROTARY CAM PROVIDED IN THE MACHINE FRAME. THE GEAR AND THE FOLLOWER IN THE SHAFT OF EACH TRANSFER DEVICE OF THE FIRST TYPE CAN BE REPLACED BY A RETAINER WHICH HOLDS THE SHAFT AGAINST ROTATION AND ALSO PREVENTS THE SHAFT FROM PIVOTING ABOUT AND AXIS WHICH IS PARALLEL TO ITS OWN AXIS WHEN THE CARIAGE MOVES WITH REFERENCE TO THE DIE BREAST.
A MULTISTAGE PRESS FOR THE PRODUCTION OF METALLIC NUTS, BOLTS OR THE LIKE HAS A DIE BREAST WITH A HORIZONTAL ROW OF WORK STATIONS AND A CARRIAGE WHICH IS RECIPROCABLE ALONG THE DIE BREAST THROUGH DISTANCES CORRESPONDING TO THAT BETWEEN TWO NEIGHBOURING WORK STATIONS. THE FRAME OF THE PRESS SUPPORTS A GEAR SEGMENT AND A COAXIAL CAM FOR EACH WORK STATION. A TRANSFER DEVICE OF A FIRST TYPE CAN BE ATTACHED TO THE CARRIAGE FOR EACH WORK STATION OR FOR ONE MORE SELECTED WORK STATIONS, AND SUCH TRANSFER DEVICE EMPLOYS A SHAFT WHICH CARRIES A FOLLOWER TRACKING ONE OF THE CAMS, A GEAR MESHING WITH ONE OF THE GEAR SEGMENTS, AND A PAIR OF ELASTIC FINGERS WHICH CAN TRANSPORT AND SIMULTANEOUSLY INVERT A BLANK DURING MOVEMENT OF THE CARRIAGE WITH REFERENCE TO THE DIE BREAST.

| A transfer system is disclosed for progressively transferring work pieces between die stations of a progressive forging machine. The transfer includes a pivoted frame on which a reciprocating slide is supported. Work pieces gripping fingers are carried by the slide for movement from a gripping position to a release position. Pivotal movement of the frame moves the fingers out away from the die face to provide clearance for turning of the fingers. Finger turning is in response to reciprocation of the finger supporting slide. A first cam driven linkage controls the oscillating pivotal movement of the frame and a second cam driven linkage controls the gripping and release of the fingers. The two linkages are arranged to be substantially unaffected by the pivotal movement of the frame and the reciprocating movement of the slide. The transfer is arranged to permit easy removal of one slide with work piece gripping fingers thereon and the substitution of a different slide with a different type of work piece gripping fingers. Therefore, the transfer system can be easily modified to accommodate different types of work pieces and to permit different types of forming operations within a single machine.

| A KNOCKOUT ASSEMBLY FOR USE IN A FORMING MACHINE HAS A ROD WITH A TIP SHAPED TO FORM A DESIRED INDENTATION IN A WORKPIECE AND A SLEEVE WHICH SURROUNDS THE ROD TO EJECT THE WORKPIECE FROM THE MACHINE. THE ROD AND SLEEVE ARE SLIDABLY MOUNTED IN A BODY. AN ARRANGEMENT OF CAMS CAUSES THE SLEEVE TO MOVE A GREATER DISTANCE THAN THE ROD AND THEREBY STRIP THE WORKPIECE FROM THE TIP OF THE ROD AND EJECT IT FROM THE MACHINE.
