Abstract: 28,264. Coates, F. Dec. 15. Labelling. - In machines for affixing labels or seals around boxes and like articles, the labels &c. are fed alternately or successively from two or more label supplies. Articles bare pushed from a hopper H, Fig. 5, by a pusher 35 into position beneath a plunger 36, Figs. 5 and 7, where they are held between a fixed flange 37 and a plate 38 carried by a lever 41, which is pivoted at 39 to the plunger and acted upon by a spring 42. Labels are taken alternately from piles B<1>, B<2> by adhesive separators 92, and are seized by grippers pivoted at 125 to a slide 68 which deposit them above a vertical shoot R. The plunger 36 then descends and presses an article and the label into the shoot, thus folding the label over the ends of the article, which has been released from the plunger by a stop 69, Fig. 7, rocking the lever 41. Wipers P, P<1>, Figs. 5 and 12, carried bv arms 142, 143 pivoted at 119, wipe the upstanding ends of the label on to the upper side of the article. One side 73 of the shoot R is ressed inwardly by springs so as to hold the labelled packages frictionally as each one added presses the previously-labelled ones farther into the shoot, thus allowing the adhesive time to dry before the articles leave the shoot. The pusher 35 is reciprocated by a rod 54 and a crank 55 turned by a pinion 56 in engagement with a rack 60 attached to a slide 61, which is reciprocated by a rod 63 and a crank-disk 46, Fig. 7, on a shaft 30 This .disk is also a cam and raises the yoke 43 of the plunger 36 and its guiding-rods 47 against the action of gravity Cams 123 on an extension of the slide 61 hold the label-supports 88 normally in depressed position by depresing levers 117 which bear on pins 118 of the guiding-rods 89. The adhesive separators 92 are carried by slides 93, Fig. 8, and receive adhesive by contact with rollers 79 on a common shaft rotating in tanks 77. One slide 93 is reciprocated by a link 106 and a lever 107, 110 rocked by a finger 115 carried by the slide 68, Fig. 5, and the other by a lever pivoted at 102, Fig. 7 ,and rocked by a cam 98. Springs 91, Fig. 5, press the label piles up to the separators 92, and when a lever 117 depresses the corresponding pile, the top label adheres to the separators and is seized by the grippers carried by the slide 68. When recharging the label-holders, the supports 88 can be retained in the lowest position by interposing sleeves 95 between pins 97 on the rods 89 and their bosses 90; the sleeves, when not in use, are kept in a lower position on the rods by engaging the pins with slots 96 in the sleeves. The pivot 125 of the two grippers is integral with the fixed jaws 128, 136, Fig. 13, the movable jaws 127, 137 being integral with sleeves 126, 138. Springs 129, 139 normally close the jaws, and resilient stops engage with tappets 130, 140 on the sleeves to open the jaws. The slide 68 is reciprocated by a pinion 65 carried by the slide 61 and which runs on a fixed rack 66 and engages with a rack 67 on the slide 68. The wipers P, P<1>, Fig. 12, are made in the shape of troughs to receive the labels from the grippers, and are provided with rollers 149 which run over the ends of the labels. Projections on the slide 61 rock the arm 143 of the wiper P against the action of a spring 153, and a finger 163 on the yoke 164, Fig. 5, of the guiding-rods 47 of the plunger 36 raise a rod 161 to rock the arms of the wiper P<1> against the action of a spring 165, Fig. 12.
