Abstract: 1335. Weisell, D., and Lauferty, A. S. Jan. 18. Damping and affixing labels.-Relates to a labelling-machine for bottles and other articles. A carrier band is mounted on sprocket-wheels 24, and has slats clamped to it at regular intervals, the ends 42 being journalled to engage in bearings 23 on the wheels, the ends being connected by links 21. Spring clips 27 are attached to each slat, and connected in pairs by links 28, causing the clips to open when passing round the wheels, to receive a bottle from the shoot 94, gripping it while passing under the labelling-devices, and afterwards releasing it. Intermittent motion is imparted to the band from a rotating crank shaft 34, on the crank of which is mounted a forked lever 31, having a sliding fulcrum 40 at its lower end, its fork engaging, at each rotation of the crank, with one of the ends 42 of the slats, or preferably with separate pins on the links 21 to shift the bottles one stage. This arrangement is duplicated at each side of the band. Two spring pawls 41, pivoted on the frame of the machine and disengaged by the upper end of the lever during the movement of the band, lock the latter when at rest. The gumming-apparatus 44, the label holder 49, and the label presser 77 are mounted on spring plunger rods 90, attached to a frame 86, vertically reciprocated by a connecting-rod from the crank shaft 34. The devices act simultaneously on three adjacent bottles while at rest, and their lower surfaces are made to suit the size and desired position of the label, and the shape of the article to be labelled. The mucilage receptacle 44 has an india-rubber diaphragm provided with a number of circular depressions on the underside, each communicating with the interior by cross-slits which normally remain closed to keep the mucilage in the receptacle, but, when pressed on a bottle, the diaphragm stretches, allowing mucilage to be applied over the desired area. A more even distribution may be obtained by covering the diaphragm with canvas. The label holder, Figs. 12 and 13, consists of a plunger 65, the lower surface of which is shown in dotted lines in Fig. 12, and a surrounding case 49, with lips 51 on which the labels rest. The case and plunger are connected by spring pawls 75 on the plunger engaging spring ratchets or corrugated plates 70 placed in slots 69 in the case and having a slight vertical movement therein, limited by the top corrugation, and a hook 76 engaging the rim of the case. Hooks 57 normally support the labels at the centre, but are disengaged when a spring- returned roller 54, in a yoke 55 on the case, is moved outwards by coming in contact with the bottle 18, allowing the lowest label 76 to be attached to the bottle. As the plunger rises slightly without the case, the resiliency of the labels causes them to rise at the centre, allowing the hooks again to engage with the next label as the case is raised. As the pile diminishes, the pawls 75 engage with lower corrugations on the ratchet. The positions of the plungers or rods are roughly adjusted by pins 91, Fig. 1, inserted in one of a number of holes at the upper ends of the rods, finer adjustment being allowed by the springs 90. After the label has been attached, it is firmly pressed on the bottle by a flexible diaphragm 77 on spring supports 80.
