Abstract: 302,641. Winkler, A., and D³nnebier, M. Dec. 19, 1927, [Convention date]. Feeding articles in predetermined attitude by lifting from loose assemblage in bin.-Apparatus for setting upright, work pieces, e.g. confectionery centres, in transit to a machine, e.g. a coating machine, comprises a conveyer 46 on which the centres are deposited and wavy, elastic guides 32, positioned above the conveyer, which are reciprocated transversely of the conveyer to shake the centres until they come to rest on their bottoms. The guides 32 are held at their ends on pivot bolts 37 adjustably mounted on cross bars 34, 35. An intermediate cross bar 36 is reciprocated by an eccentric 53, connecting rod 52, and bell-crank levers 49, 50. The guides 32 each consist of a straight length and a separate wavy length, the two lengths being joined by the pivot 'bolts 37, Fig. 6, being threaded through ringed lugs 39 on the guide rail lengths. The bar 36 is slotted to permit transverse adjustment of the bolts 37 which are flatted to engage the slot. The spacing between the guides 32 and the conveyer may be altered by adjustable screws 38 which secure the fixed bars 34, 35 to the machine casing. The conveyer 46 passes over a table 4 and is trained over rollers 25 - - 31, the roller 31 being journaled in an arm 56 coupled to a tension spring 55, for tensioning the conveyer. The roller 26 cleans the conveyer, a spring- pressed scraper 57 coacting with the roller 26 and delivering the foreign matter, e.g. sugar, into a receptacle 59. The centres are placed in a hopper 5 which is partitioned to separate varieties, the partitions being tapered towards the outlet to prevent jamming. The bottom of the hopper is formed by an inclined, endless, ribbed conveyer 8, and the hopper is movable, to vary the inclination of the conveyer 8, by mechanism 11, 12, 13, 15. The conveyer 8 is operated intermittently by pawl and ratchet mechanism, adjustment of the stroke being permitted by a slotted link 22. The inclination of the conveyer 8 tends to make the centres fall backwards into the hopper and ensures a rough uniformity of spacing. Jamming at the outlet is prevented by rotarv brushes 19 intermittently operated by ratchet mechanism, or alternatively, oscillating brushes may be used. The centres are discharged over a shoot 87, having partitions 88 corresponding with the hopper partitions, on to the conveyer 46. The machine is driven by a shaft 60, which may be the usual shaft for driving the replaced feeding conveyer for the coating machine. The shaft 64 is driven through chain gearing 63 and carries rollers 65, 66 feathered on the shaft. and independently slidable thereon by adjusting screws 81, 82. The rollers 65, 66 frictionally drive discs 67, 68 on transverse shafts 69, 70 respectively, the shaft 69 driving the roller 25 through bevels 71, 72 and worm gearing 74, 76. The shaft 70 carries the eccentric 53 for reciprocating the bar 36 and the eccentrics for actuating the conveyer 8 and the brushes 19. The guides 32 and the conveyer 8 are, therefore interconnected in their adjustable movements, whilst the motion of the conveyer 46 is independently adjustable.
