Abstract: 14,198. Adriance, B. June 23. Metal, sheet, seaming and joining.-Relates to a machine for fixing heads on cans. The machine consists of a pedestal a, Fig. 1, with projecting arms b, c, d. In the arm d is secured by screws v the vertical flanged posts, Fig. 4, on which is journalled the d i s c w, capable of being revolved by the horizontal shaft f through the b e v e lwheels g, z. At opposite points on the disc w are arranged similar pairs of levers A, B, Fig. 3. The lever a<3>, Fig. 5, is fulcrummed in the disc w by the boss a', and carries at its free end a roller b<1>, Fig. 4, which engages the groove b<2> made in the under face of the block a<2> and conforming to the outline of the can, the block a<2> being secured to the post s. The lever b<3> is pivoted to the lever a' by the bolt b<4>, and carries at one end the shaping-roller b<5> and at the other the vertical stud c<1>, which projects through the slot c<2> in the lever a<3> and carries a roller c<3> at its top. The shaping-roller b<5> of the lever b<3> in the mechanism A is shown in Fig. 9, while that of the mechanism B is shown in Fig. 10, the two mechanisms being otherwise identical. On the shoulder c<4>, Fig. 4, of the disc w is arranged a ring c<5>, formed with peripheral cams d', d<6>, and a bevel gear d<2>, gearing with the bevel-wheel h on the shaft f. The cams d<1>, d<6> are made to gear with the wheels c<3> of the levers b<3> in the mechanisms A, B respectively. The can, with the head arranged as shown in Fig. 11, is placed on the table e', Fig. 4, and the wheels c<3> are made to gear with the lowest elevations d<5>, d<9> of their respective cams d', d<6>. By means of the treadle f the table e<2> is raised, so as to force the can against the chuck a<2> and hold it. The handle r is then pushed over, which causes the friction clutch k to engage the belt pulley i and to set the bevel-wheels z, d<2> in motion. These are so arranged that six revolutions of the wheel z correspond to five of the wheel d', so that the disc w with the levers b<3> revolves around the can and gradually gains on the cams. The cams d', d<6> are so arranged that, for the first three revolutions of the disc w, the wheel c<3>, gearing with the cam d<6>, remains in its lowest elevation, and so keeps its shaping-wheel b<5> out of contact with the can, while the wheel c<3>, gearing with the cam d', forces its shaping-wheel against the can, thus rolling the flanges of the can to the shape shown in Fig. 12. During the fourth revolution of the disc, the shaping-wheel of the mechanism A is put out of action, and that of the mechanism B comes into play and finishes the can, as shown in Fig. 13. At the end of the sixth revolution, the wheel c<3> of the mechanism B gets into the lowest elevation of the cam d<6>, and in this position releases the catch o, Fig. 3, which is keeping the friction clutch k locked, against the action of the spring q. The clutch is thereby unlocked, and, at the same time, the band brake g', one end of which is attached to the rod m as shown in Fig. 1, is applied, so as to stop the machine and allow the can to be removed.
