the right as viewed in fig2 link members 52 and 54 are threadably connected together so that their overall length can be adjusted link means 60 comprises a link member 62 and a shorter link member 64 threadably connected together at 66 so that the overall length of link means 60 can be adjusted pivot means 68 connect link member 62 to link member 52 while pivot means 70 connect link member 64 to carriage 28 the arrangement is such that as the link means 60 is pivoted link means 60 causes the extractor arm to move either toward the press or away from the press as viewed in fig2 as link member 50 is pivoted toward the left the extractor arm moves toward the press and as link member 50 is pivoted toward the right the extractor arm moves away from the press cam plate 72 is mounted on frame 18 adjacent the path of motion of the extractor arm the cam plate has a cam slot 74 which as viewed in fig1 has a generally vertical section 76 that is generally parallel to the direction of motion of ram 16 and an inclined portion 78 that is inclined with respect to the path of motion 16 of the ram connecting member 80 is connected by pivot means 82 to an arm 84 that is attached to ram 14 connecting member 80 is also formed of two telescopically threadably engaged members 86 and 88.
