Abstract: 26,951. Beadle, G. W. Nov. 19. Paper pipes and tubes.-Consists in a machine for turning-over the ends of cartons for dry cells and the like, in which the cartons are fed on to collapsible mandrels, which carry them into contact with rotating spinning-tools for bending their ends over in stages. Figs. 4 and 6 show sectional views on the planes 4, 6 of Fig. 2, which shows the whole machine in side view. The blanks are fed from a hopper 98, Fig. 2, on to mandrels 74 carried by a frame 76 which is driven from the power shaft 5 through intermittent gearing 7, 11 so as to carry the cartons forward by steps. During the rest periods their ends are engaged by the spinning-tools 21, 23, 28, the driving-gear of which is shown in Figs. 4 and 5. The tools, which are constantly driven from the shaft 5 by a wheel 13 and the gear train 20, 220, 27 shown, have concentric spinning-grooves 31, and at intervals they are moved axially to engage the ends of the cartons by means of an intermittently - driven crank 51 and rod 52, Fig. 2, and the linkages shown in Fig. 6. The links 64, 57, 68 are coupled at 66, 62, 70 to clutch members 32, 33, 34, engaging corresponding members on the tool shafts 22, 24, 29, Fig. 5, which pass freely through both members and are normally retracted from the cartons by compression springs 42 outside the auxiliary framing 40. Reciprocation of the rod 52, Fig. 6, rocks the members 32, 33, 34, which, by abutment on the collars 130 on the tool shafts, move the tools on to the stationary cartons. A carton 73 is shown in Fig. 7 on its mandrel in proximity with a retracted tool 21. The mandrel consists of cylindrical segments 80 normally drawn together by internal springs 86 and adapted to expand outwards, to grip the carton, under the action of radially - moving blocks 81. The blocks are moved in slotted guides 100, 101 by cones 82 on the shaft 83, the tip 84 of which is reduced to enter the tool for rigidity during the spinning operation. The shafts 83 are advanced to grip the cartons by a cam-ring 90, Figs. 2, 13, which is supported by a fixed ring 92 and is cushioned by springs 91. The shafts are retracted, to collapse the mandrels for discharging the treated cartons by the passage of their recessed ends 95, Fig. 7, between gripping-rails 97, Fig. 13, mounted on the ring 92 and sloping oppositely to the advancing-cam 94 on the ring 90. The device for feeding the cartons on to the mandrels and removing them is shown in Fig. 16, and is driven from the crank-rod 52, Figs. 2 and 6, by a link 58 and gear-wheel 60. It comprises a pair of oppositely-reciprocating racks 690, 700, the former of which carries an upright 710 and feeder-bar 720, Figs. 2 and 4, for feeding the cartons 73 from a hopper 98 along a guide 120 and on to the mandrels. The lower rack carries a pivoted dog 108 which pulls the treated cartons off from the mandrels. The mounting and removal of the cartons are timed to occur when the mandrel frame 76 is at its locked positions, but a spring 127, Figs. 2 and 16, is interposed between the feederbar and rack 690 to prevent strain should the mandrel not be accurately alined when the gear 60 begins to advance the rack. A gas pipe 111, Fig. 4, may be used to heat the tools. A printing-machine as described in Specification 10,756/11, [Class 100(ii), Printing processes &c.], may be attached to the machine.
