Abstract: 124,367. Rosengren, A. A. July 31, 1918. Capsules, ' crown corks,' and the like, applying.-Relates to machines for making and applying capsules to bottles or other vessels, and of the kind described in Specification 29023/13, in which blanks punched out from a strip of material are formed into capsules by dies, which are carried by an intermittingly-rotating member and are provided with movable parts or bottom-pieces corrected to each other so that the bottom-piece of a die containing a finished capsule expels the same and applies it to the bottle &c.- The tool that punches out the capsule blanks is combined with a device that punches out disks from a single or composite material to rest against the mouth of the vessel under high pressure to close it hermetically, the tool that punches out the disks being slidably surrounded by the tool that punches out the capsule blanks. The disks are composed of a layer of an elastic substance such as cork or imitation cork, and a layer of a firmer substance such as parchment or a soft metal or alloy. The punch 29, Fig. 8, which forms the disks is actuated by a lever 27, Fig. 2, operated by a link 30 from a lever 32 moved by a cam 34, and the tubular punch 48 which forms the aluminium &c. capsule blanks with their tearing-off tongues is carried by a head 47 pivoted on levers 46 operated by links 49 from a lever 51 moved by a cam 10. Springs 43, 48<a> effect the return movements of the punches. The strips of material from which the disks are punched' are fed from coils 53, 54 through a recess 64 in the punch 48 by rollers 98, 106, and the strip of aluminium &c. is fed from a coil 55 through are. cess 68 in a ring 67 beneath the guide-sleeve 66 of the punch 48 by rollers 107, 108. The rollers 98, 107 are cam rollers, and the rollers 106, 108, which serve as counterpressure rollers, are mounted on eccentric journals so that they can be displaced laterally and the feed stopped by turning a crank 100, Fig. 2. The strips pass over surfaces 56, 57 against which they are pressed by rollers 60. The waste material is cut by two shearing- members 39, 40, Fig. 3, pivoted at the front side of the frame head 3, Fig. 2, and operated by a link 38 and lever 37 from the lever 27. The die cylinder 70 is rotated intermittingly through half a revolution by a half-wheel which gears with a wheel on one of the cylinder journals and is driven by bevel-gearing from the shaft 13. The walls of the dies are formed by the ends of a tube 77, which is arranged within the cylinder and has a central flange 78 with springs 79 between it and the cylinder, while the bottoms of the dies are formed by the heads 80 of a bar 81 which is situated within the tube 77 and surrounded by a spring 85 bearing against sleeves 82. The punch 29 and heads 80 may be.arranged to impress any desired information on the capsules. For locking the cylinder during the formation of a capsule, pivoted bars on the head 47 engage in openings in the cylinder. The bottle-support 20, Fig. 2, which is carried by a plate 19 at the upper end of a spindle 18 adjustable in a sleeve 17, is moved up and down by a cam 14 engaging a roller 16 on the sleeve. A screw 22 in the plate 19 is provided for adjusting the screen 21 against which the bottles are placed. A removable slide 88, Fig. 3, in the bottom part of the frame head 3 carries a rubber ring 89 which presses the capsule into a groove in the bottle-neck when the punch 48 contacts with a metal ring 90 resting on the ring 89. In operation, a disk formed by the punch 29 is forced downwards on to the capsule blank formed by the tubular punch 48, and as the punch 29 passes into the top end of the tube 77, the blank is formed into a capsule with the disk inside it. Simultaneously, the finished capsule under the lower head 80 is forced down on to the mouth of the bottle and the rubber ring 89 compressed. On the return movement of the punch 48, the capsule is freed from the ring 89 and the bottle-rest descends. The vertical shaft 13 is driven by bevel-gearing from a shaft 9 driven by spur gearing 7, 8 from the driving-shaft 4, and the cam 34 is formed in one with the wheel 8, while the shaft 9 carries the cams 10, 14. A pivoted flap 115 with a locking-device allows the parts within the head 3 to be inspected. When applying crown-corks and like capsules of stiff material, the rubber ring 89 is replaced by an annular series of fingers 117, Fig. 13, carried by an annular shaft 118. An elastic ring 119 surrounds the hubs of the fingers 117, and a ring 120 situated within the fingers and shaped as a buffer-spring effects the return movement. An elastic ring 121 within the spring 120 serves as a guide for the bottle heads, and a ring 122 against which the tube 77 contacts rests on the top ends of the fingers. To allow for bottle-heads of different diameters &c., the annular shaft 118 is cut open at one point to allow it to widen and contract.
