23,621. Busse, W. Oct. 29. Paper &c. bags ; packeting granular, pulverulent, &c. materials. - Relates to a machine for making bags of paper, tin foil, &c., filling them with measured quantities of material, and closing the packages. The paper &c. is fed intermittently from the roll 62, between the rollers 63, 64 operated by toothed gearing from the shaft 174, to a rotating die of square section, against which it is held by the tongue 45 and around which it is rolled. The upper support for the die consists of the ring 2 made in halves 5, which are moved for adjustment for packages of different sizes by the screw bolts 6, passing through threaded holes in the ring halves 5. The angular irons 9<1>, 9', 9<3>, 9<4> forming the die are adjusted by the bolts 10 moving in the diagonal bosses 8 on the parts 5. Pins 12 engage the slots 11 in the bosses 8, and the curved slots 13 in the ring plate 14, which has teeth 15 engaging the catches 16, mounted on the axle 18, but capable of lateral motion on the feather 19 when the parts 5 are moved in or out. The axle 18 is connected by the levers 19<1>, 21, 22 to the vertical axle 23, spur-wheels 27 on which engage teeth on one of the halves of the ring plate 14. The spur-wheel 28 engages the toothed segment 34, which is pivoted to a plate having a scale 32. To each of the handles 30, 33, loose handles 31<1>, 33<1> are linked, having claws engaging with teeth, so that the segment 34 can be secured in any position relatively to the scale 32, and the scale in any position relatively to the framing. The angleirons of the die form a hollow prism, the size of which is first adjusted by turning the bolt 6, the finer adjustment being then obtained by moving the segment 34, which rotates the ring 14, and, by means of the pins 12 in the slots 11, 13, moves the parts 9<1>, 9', 9<3>, 9<4> towards or away from each other. A similar adjusting-device worked from the same axle 23 is used for the mould into which the bag falls. The trap 37 at the bottom of the die can be raised by the racks 35, 38 and toothed gearing 36. The rack 38 is connected with a parallel guide consisting of sliding rods 39 with a projecting arm 40. The axle 42, mounted between the rods 39, supports the tongue 45, which is covered by an india-rubber plate. When the guide 39 descends, the lever 46 is pushed aside by the core 47, against the action of the spring 50, thereby moving the tongue 45 away from the die ; at the same time, the trap 37 is rotated. The descent of the guide is effected by the lever 49, actuated by a cam on the shaft 174, pressing against the arm 40. Lengths of paper &c. are cut off by the knife 68, operated by a pin mounted on a disc on the shaft 174. The edge projecting from the tongue 45, and the flaps to form the bottom of the bag, are glued by the bands 87, 76<1>, supplied from the reservoir 70. The axle 71 in the reservoir is rotated by worm gear 72. The band 76<1> passes over a disc on the axle and the disc 76 on a stud on the bracket 77, Fig. 14. The band is moved forwards three times during the rotation of the die, by catches on the disc 165, which engage the rod 78. The band is withdrawn by the spring 79. The band 87 is brought against the edge of the paper &c. by the action of the cam 91 on the shaft 174, which engages the lever 92, connected with the guide - roller 89. Fig. 18 shows the mechanism by which the four bottom flaps of the bag are folded up beneath the lower edge of the die. The plate 116 with roller 115 is moved horizontally four times during one revolution of the die, the cam 117 operating the axle 121. The plate 116 is guided by the sleeve 114 sliding on the axle 127. Before each movement, the band 76<1> advances and glues the corresponding flap. The top flap is prevented from falling by the trap 124 connected to the sleeve 125 on the axle 127, which is oscillated by the rod 126, Fig. 1, from the cam 58. The plate 124 is pressed upwards by a spring, and is depressed by a nose each time the roller plate 116 advances. The overlapping edge of the paper &c. is pressed against the edge glued by the band 87 by the apparatus 98, Fig. 2. The sleeve 105 sliding on the axle 104 is operated by cam mechanism. The bar 109 has a pin 110 which engages an inclined slot in the sleeve 105, so that, when the sleeve descends, the bar is pressed against the edge of the paper. By means of the arm 112, abutting against the pin 113 in the sleeve 105, the whole device is caused to rotate on the axle 104, moving the bar away from the die. When this occurs, the trap 37 moves upwards, and the plate 124 swings downwards. A measured quantity of material falls from a feeding-drum through the die, and the bag and material fall through the guide 131 into the mould 52. The support 53 for the package passes through an opening in the side of the mould, and swings around the nut 56 on the bolt 55 fixed in the eye 54 of the ring 3<1>. The support is pressed upwards by the spring 57 ; it is operated by the cam 58 on the shaft 174, and the levers 59, 60. Figs. 21 and 23 show the device for glueing and folding up the top of the package. Pins 141 on the glue vessel 140 engage curved slots in the discs 142. The vessel is moved by the lever 143 fixed to the axle 144, operated by the levers 145, 146 and the cam 147 on the toothed segment 66, and in advancing folds over one flap of the bag. The glueing- levers 149, pivoted to the guide 131 are moved upwards during the forward motion of the vessel 140 by the levers 148 pivoted on the pins 141. They lightly touch the upright paper flaps, and are returned by the springs 150. Within the vessel 140 is an angle-lever, the shorter arm of which pushes against the guide 131, causing the balls 151 on the longer arm to transmit glue to the levers 149. The movable plates 152 are drawn against the die by the catches 153, and are released when the rotation of the die begins. The three remaining flaps are folded over by the roller 155, which is moved to and fro in a similar manner to the plate 116. The package then drops from the machine. The various parts of the machine are operated by toothed gearing from the shaft 160, as shown in Fig. 1. If the glue used does not dry quickly, the apparatus shown in Fig. 26 is used. The bag filled with material falls from the upper die into the heating-chamber 181, which has hollow walls containing adjustable plates 182, 183, carrying the pivoted folding-flaps 184, 185, which are operated by means of toothed wheels 186, 187 from the racks 188, 189. The racks are mounted on the sliding guide 190<1> in such a manner that, during the movement of the chamber 181, first the flap 184 falls and folds down the paper, and then two lateral arms are turned over and press the side paper flaps against the walls of the vessel 181. The flap 185 then falls over and folds the opposite paper flap. The glueing-vessel 190, operated by lever mechanism 211 from the cam 212 on the shaft 174, descends, glues the two last paper flaps, and returns. The heating-bottom 198 of the vessel 181 swings around the stod 199 to allow the package to fall into the mould 52. The vessel has also a movable bottom which rises through the vessel, swings round to receive a package from tbe die, and guides the package into the vessel and on to the bottom 198.
