Abstract: 13,581. Rose, W., and Rose Bros. June 7. Labelling.-Relates to the general construction of machines for affixing labels, wrappers, or bands around three sides of boxes, blocks, or packages. Packages 1 are conveyed along a trough 3, Fig. 3, by a band 4, to an obstacle 19, and a plunger 20, Figs. 3, 4, and 8, pushes them sideways from the trough to be pushed by a plunger 21 which acts transversely to the plunger 20, into a holder 22. The plunger 20 is carried by a frame 24 which reciprocates on a bar 25. If the packages have been previously wrapped, the loose ends of the first wrappers are pressed down by the plunger 20 and by a jaw 36 pivoted at 37 to the frame 24. A spring 38 normally closes this jaw, and a roller 39 on the arm of the jaw runs on a fixed cam 40 to open it. The holder 22 is carried by a frame 54 which is reciprocated vertically on bars 55, and it may have resilient sides to allow for variation in the lengths of the packages. Labels or wrappers are carried from a pile - holder 63, Fig. 4, and deposited by an adhesive separator 64, acting in the manner described in Specification 15,559/10, [Class 100(i), Feeding and delivering webs &c.], upon a device 66 which rocks on a shaft 69 and applies the label to the package in the holder 22. The device 66 comprises two plates 67, 68, Fig. 16, carrying spring grippers 70 for holding the ends of the labels, these grippers being opened by pivoted fingers rocked by cams and striking arms 73 carried by the grippers. The plate 67 is adapted to slide along the shaft 69 so that before the plates 67, 68 apply a label to a package, they and the grippers are forced apart by a spring 93 to stretch the label. A cam 94 on the plate 67 runs on a fixed roller 95 to bring the grippers nearer together before receiving a label. The ends of the label are folded over the ends of the package 1 by plates 97, Figs. 4, 23, and 24, pivoted at 113 to a carrier 98 which turns on pivots 102 in arms 99 rocking on a shaft 90. The folders 97 close under the action of a spring 114 to grip the package, and the arms 99 rock to carry the package up to a trough 101, into which it is forced by a plunger 112 reciprocated by a rocking arm 129 and a link 131. As the package is being raised to the trough 101, it is turned so as to enable brushes or the like, with which the trough is lined, to smooth down the ends of the label on the package. This turning is effected by the carrier 98 being turned on the pivots 102 by a roller on an arm of the carrier running in a fixed cam-groove 110. During the upward movement of the package, it is supported by a forked arm 119 pivoted in the carrier 98 and rocked into position by a roller 124 on a crank-arm 123 which is integral with the pivot of the arm 119 running on a cam - arm 125, Fig. 4. This cam - arm is pivoted at 46, and is rocked into position by a cam on the main driving-shaft. The rocking of the folders 97 against the action of the spring 114 is effected by a projection 115 on the arm 119 engaging with tappets 117 on the folders. The forked arm 119 is adapted to pass through gaps 118, Fig. 3, in the plunger 21 that pushes the packages into the holder 22. The operation of the several parts of the machine is effected by cams on the main driving- shaft.
