Abstract: 234,352. Imray, O. Y., (Aluminum Co. of America). Sept. 29, 1924. Capsuling. - In a machine for securing closure caps on bottles &c., a shaft which is movable longitudinally but is non-rotatable, carries, journaled on it, a rotatable head movable axially with it as a unit. A standard 11, Fig. 1, on a casing 1 is provided with a bracket 13 formed with a hollow boss 21, Fig. 2, carrying a sleeve 22 which secures to it a plate 26 supporting an annular cam track 30. A non-rotatable shaft 32 adapted to slide in the sleeve 22 is pressed downwardly by a spring 17 which abuts against a plate 16 mounted on rods 15, 15<1> threaded through projections 14, 14<1> on the boss 21. A rotary spinning head 45 mounted on the lower part of the shaft 32 carries vertical rock shafts 69, 59<1>, Fig. 6, adapted to be operated by two-part levers 60 secured to the upper ends of the shafts. Each lever 60 comprises an arm 65 and a part 61 carrying an arm 63. Each arm 65 is rotatably mounted on the shaft 59 or 59<1> but is yieldingly secured to the part 61 by a bolt and nut 68, 70 and a spring 69, the bolt 68 passing through a depending lug 67 on the arm 65 and contiguous lug 64 on the part 61. The arms 63 of all the levers 60 are connected together by springs, the arrangement causing rollers 66 on the ends of the arms 65 to be pressed outwardly against the cam track 30. To the lower end of each rock shaft 59 is secured an arm 71 on which a spinning disc such as 81 is rotatably mounted, the disc being supported by a spring 79 abutting against a nut 78 on its spindle 73. In operation a support 7, Fig. 1, and a bottle &c. 10 are raised by a cam 3 against the action of a spring 8. The bottle is provided with a stopper 88 and a tubular capsule and is guided beneath the spinning head by an apertured guide plate 101 secured to the standard 11. The stopper 88, Fig. 2, contacts with the tapered end 42 of a spring-pressed plunger 41 mounted and fitting in a recess in the shaft 32, the pressure ensuring proper closure of the bottle. The continued rise of the bottle causes a shouldered portion 91 of the capsule to engage a shoulder 40' on a sleeve 38 secured to the shaft 32 to raise the shaft, a packing 40<11> then engaging the top of the stopper. In this position the surface formed bv the sleeve 38 and the end of the plunger 41 is substantially continuous. The upward movement of the shaft 32 lifts the spinning head 45 whereupon the cam-track 30 presses the rollers 66 on the arms 65 of the levers 60, radially inwardly rocking the shafts 59 and bringing the spinning discs 81, 82 into contact with the capsule. The discs which engage the skirt 92 of the capsule at different points axially of it, press it into close engagement with the neck of the bottle, the springs 79 permitting them to adjust themselves vertically and the springs 69 on the levers 60 allowing them to yield laterally to any irregularities in the surface of the neck. The spinning discs are adapted also to adjust themselves to a threaded bottle neck, the screw capsule thus formed being adapted for repeated removal and replacement.
