Abstract: 656,497. Making fillers for boxes. MAYHEW, J. H. Oct. 5, 1948, No. 25922. Convention date, Oct. 13, 1947. [Class 18] A machine for assembling cardboard partitions to form fillers for boxes comprises a conveyer operating between a receiving position where dispensing mechanisms place a group of spaced partitions into holders on the conveyer, and an assembly position where further dispensing mechanisms advance a group of spaced partitions into crossed engagement with the first group. The machine is capable of adjustment to assemble fillers of various overall dimensions and all sizes. The conveyer, Fig. 33, is a rotary turret, the arms 7 of which carry spring clips 8<SP>1</SP>, 9'. It is given angular shifts of 90 degrees by rack and pinion mechanism 36, Fig. 3, operating from the driving shaft 26 of the machine. The turret is disconnected from the mechanism 36 towards the end of each shift and its movement is checked by brake shoes 82, acting on a plate 81, one of which plates is attached to each arm 7, Fig. 1. The turret is finally indexed in position by a plunger entering a hole in the turret boss 6. The brake and plunger are automatically disconnected at the next shift. The clips 8<SP>1</SP>, 9' are adjustable on the,arms 7. The dispensing means comprises adjustable capacity reservoirs 109-112, 176 of partition blanks, Fig. 1. The reservoirs 109-112 are mounted in pairs on tables 131, 132 which are adjustable towards and away from the turret. The pairs of reservoirs are vertically adjustable relative to each other by chain-connected nuts 137 operating on screwed columns 135, 136. The blanks are advanced by flat pushers 142, 187, connected to reciprocating heads 145, 146 operated from the shaft 26. Means are provided in the case of the reservoirs 110, 112 to force back the train of blanks extending from the reservoirs along the pusher guides 114, 116, to prevent interference between blanks overlapping the ends of-these guides and those held by the turret during movement of the latter. The means, comprising reciprocating teeth 198, Fig. 1, are operated from the heads 145, 146, by rods 206. The rod 206 attached to the head 146 also controls a positioning plate 213 which ensures that partitions fed by reservoirs 109, 110 are not displaced from the turret holders 8<SP>1</SP>, 9<SP>1</SP> by blanks fed from the reservoir 176. Operation. A pair of blanks X are fed to adjacent holders 8<SP>1</SP>, 9<SP>1</SP> from the reservoirs 109, 110 and the turret is revolved to bring the blanks X to the assembly position when two blanks Y from the reservoirs 111, 112 and one blank Z from the reservoir 176 are fed forward to engage the blanks X to complete the filler. The completed filler is removed from the clips 8<SP>1</SP>, 9<SP>1</SP> by jaws 223, 224, Fig. 3, which grip the partitions X when the turret is in its indexed positions and retract, holding the filler. The filler is ejected from the machine by spring loaded pushers which operate upon the jaws 223, 224 being opened, the filler falling clear between the moving arms of the turret.
