Abstract: 18,696. British American Machinery Co., Pollard, E. T., and Behrmann, E. L. Sept. 15. Making boxes; cigar and cigarette boxes.-Relates to improvements in machines of the type described in Specification No. 19,271 A.D. 1902, in which box blanks cut from a web of paper or cardboard are transferred to an intermittently - rotating carrier-wheel, at the successive stages of rest of which the box is formed, then filled with cigarettes &c., and closed, being finally ejected from the machine. The web is drawn from the roll 6, Fig. 1, by the oscillating cam-operated lever 5, and is printed in two colours, bronzed, and polished by ordinary machinery. It is fed to the cutting and scoring dies 10, 11 by grippers 20, 21, Figs. 1 and 4, carried by a horizontally-sliding carriage 15, oscillated by the crank 18. The grippers 20, 21 are opened by the projection 22 on the rod 17 pressing down the pin 23 fixed to the lower gripper 21. The dies 10, 11, the lower of which is oscillated by the eccentrics 12, Fig. 1, cut and score the blank to the form in Figs. 25 and 26, but do not entirely sever it from the web. During the next forward movement of the slide 15, the hooks 24 engage the cut blank behind the flaps g and feed it beneath one of the moulds in the rotating mould-wheel 28, Figs. 1 and 2, which is driven by a pawl 32 on the oscillating slotted lever 31, engaging the teeth on the face of the wheel. As the die 11 again rises, the cut blank is severed from the web and its portion a is forced into one of the moulds 34, Fig. 7, thus bending upwards the flaps f. At the same time, the flaps g are bent slightly upwards by the part e being forced into a shallow mould 35, Figs. 1 and 2, carried by the shrouding of the wheel. As the die 11 again descends, the piece 36, Fig. 7, slides inwards to prevent the descent of the blank. When the mould-wheel has rotated through an angle of sixty degrees, the forward flap g is bent at right-angles to the portion e by the fixed plate 39, Fig. 7. The rear flap g is bent upwards by a plate 46, fixed to the oscillating piece 40, which is guided by the pin 41 and slot 42. Paste is then applied to the raised flaps f by two small rollers 51, Fig. 13, which normally rest against the rotating paste-roller 52 and are carried by an oscillating saddle 47, Figs. 1 and 2, reciprocated horizontally by the rod 49. The bottom a and back e of the box are folded into the position indicated in Fig. 29 by means of the device shown in Fig. 9. The folder 66, which is pivoted at 65 and is pressed by the spring 67, has pivoted to it at 68 a second folder 69 carrying a piece 70, engaging with the slotted piece 64, fixed to the oscillating spindle 57, Fig. 7. As the spindle 57 turns, the folders 66, 69 turn together, pressing the parts d, e of the blank before them until the folder 66 is stopped by a projection on the bracket 56. The folder 69 then continues its motion alone until the folding of the part e is completed, the flaps g resting within the flaps f. When the mould-wheel comes to its next stopping-place, a heated iron 71, Fig. 13, is inserted in the box to dry the paste. At the two succeeding stopping-places, the flaps f, g are pressed together by rollers 72, 73, thus completing the manufacture of the box.
