Abstract

102,988. Plympton, F. K. Jan. 6, 1916. Bottle covers; labels.-Apparatus for making bottle closure-disks with metal tabs or extractors, shipping or price tags, &c. is described with special reference to making closure-disks, of the type described in Specification 11881/08, [Class 125, Stoppering &c.], in which a disk a, Fig. 15, oi paper or the like is furnished with a U shaped metal strip b which clasps the edge of the disk and has one or more burrs b<2> clinched into the lower surface of the disk. The machine is furnished with two sets of mechanisms for forming and combining caps and extractors. A strip 1 of paper &c. is fed by intermittentlyrotating rollers 2, 3 to a bed 4 beneath printing or embossing plates 5, and disks bearing the imprints are cut out by a punch 6 and die 7 and pass to devices for applying the tabs, after which a transferrer 8 directs them to paraffining- rollers 9, 10, or discharges them from the machine. The metal strip b<5>, Fig. 5, from which the tabs are made, is fed by roliers 97, 98 to a punch 103, which forms the hole b<4>, Fig. 15, for use in removing a cap from a bottle &c. The punch 103 is pivoted to a spring-pressed arm 106 operated by a striker 111 on the adjacent head 50. The punches 112 which form the burrs b<2> coact with a die 113 and project upwardly from a slide 114 operated. from the shaft 14. While the punch 6 is in the raised position, the metal strip b<5> is fed on to a spring-supported anvil 90 with the burr, b<2> overlying the portion 91<a>, Fig, 8, of the anvil. The base of the punch 6 is hollowed out, leaving a rim 6<b>, Fig. 6, and a radial portion 6<c>, which pushes the punched-out. disk into a pocket on the anvil 90 and clinches the burrs b<2> into the disk. A cutter 121 carried by the slide 114 severs the tab from the strip and bends the projecting portion against a flattened portion of the punch 6. On the ascent of the punch and descent of the tool 121, the upturned part of the tab is bent round the edge of the disk and pressed down by a tool 123 carried by a lever 124 operated by a block 126 on the slide 114. Small projections 91<g> upon a removable part 91<a> of the anvil bend the points b<5>, Fig. 15, at the end of the tab inwards towards the disk. The pusher 8 works through a groove 91<d> in the anvil, and is reciprocated through linkage by a crank 133 on the shaft 11. A pivoted dog 134 on the pusher engages the edge of the disk on the anvil and is tilted by a stop 136 to pass underneath the anvil; at the end of the backward stroke, the dog is raised by a spring-pressed stop 237. A flange 91<e> on the anvil prevents the disk from rising as it is pushed rearwards.
