Abstract: 1282. Butler, W. H. Jan. 19. Packeting cigarettes &c.-Boxes are made of paper and like material, and cigarettes or other articles are filled or packed into the same by apparatus, such as that shown in Figs. 1,3,6, and 17. The material from which the boxes are made is fed from a roll 3, Fig. 1, to a roller 5 having knives or ribs and scorers, by which the blank is formed as shown in Fig. 3, with bottom 8, side flaps 9, rear flaps 10, 12, and front flaps 13, 15, transverse scores 14, 21, 22, 11, and rounded ends on the flaps. The blanks, which are still integral with one another, are next fed to another part 2 of the machine, Fig. 1, where the further operations are effected, the strip of blanks being allowed to sag or drop down between both parts, so that the strip is fed independently in each part. In the part 2, the strip is fed by a reciprocating frame 25, Figs. 1 and 6, having projections 26, which engage with the side flaps 9 of each blank. The blanks are thus brought into position under the vertically-operating knife 31, by which they are severed, the knife being carried on a walking beam 70 operated by a cam on the " driving- " shaft" 55. The knife also carries projections or pads 36, which hold the strip while the frame 25 makes its backward movement, during which the longitudinal scores 16, dividing the side flaps 9 from the bottom 8, are effected by scoring-rollers carried by the frame. A weighted arm 80 on the walking beam beats down the ends of the cut-off blank to facilitate its engagement with pickers 37 on an endless belt 38 by which the blank is now fed. The blank is thus carried into a trough having sloping sides, by which the side flaps 9 are raised, and, when brought into position under a receptacle 43 containing the cigarettes or other articles, the cigarettes &c. are filled into the partially-folded box by a pusher in the manner described in Specification No. 23,715, A.D. 1899. The rear flap 10 is now set up by a feeder 45 having two arms 46, 47 set at right-angles to one another and pivoted to the belt 38, the arm 47, which hitherto lay flat, being now lifted by means of a cam, against which the arm 46 abuts. The flaps 13, 15 are next raised and the flap 15 folded over the cigarettes &c. by means of folding arms 95, Fig. 17, carried on pivoted supports 49, actuated by a cam, which arms also serve to fold the rear flap 12 over the flap 15, they being suitably curved at both sides to effect this double purpose. The enclosing shells, which are stacked in a collapsed state in a receptacle 53, are now pushed forward to enclose the filled and folded box, by a plate 112 having a shoulder 123, which engages with the bottom shells in succession, the plate being moved forward by the toothed segment 115 through a rack 113, and again brought backward by a spring 120. The shell enters a trough in which it is partially opened, being afterwards fully opened by wedge expanders 125, as described in Specification No. 23,715, A.D. 1899, and is finally pushed over. the box to enclose it, the whole falling from the machine through an aperture 54 when the plate 112 is withdrawn. When, in filling oval cigarettes, it is desired to have the longer axis vertical, the cigarettes are fed from the receptacle 43 through guides having sloping sides. Again, in order to fill the cigarettes so that the longer axes lie horizontal, the receptacle 43 is fitted with vertically-moving partitions, and the bottom of the receptacle is also corrugated to receive them in this position. In this case, two layers of cigarettes are inserted with a sheet of paper between, one layer being first inserted from one receptacle, then a paper sheet fed and cut off from a strip, and, finally, a second layer from another receptacle.
