Abstract
734,753. Endless conveyers. SYKOKIS, G. J. Jan. 3, 1951 [Jan. 3, 1950; Feb. 14, 1950], No. 237/51. Class 78 (1). In an endless chain conveyer driven at a number of points along its path by sprockets 5, Fig. 27, and comprising links 19, 20, Fig. 24, adapted to carry load supports 24, the chain is supported on both sides of two mutually tranverse planes cutting its longitudinal axis by rollers 7, 8, 9, 10 so that upon movement of the chain the rotating rollers on opposite sides . of one plane, when projected on to the other plane, rotate in opposite directions and the projections of the roller axes on both planes are perpendicular to said longitudinal axis. The rollers may be carried by the chain to engage fixed tracks, Fig. 16, or the guide structure to be engaged directly by the chain links, Fig. 18, or both, Fig. 20, are shown. Each embodiment shown except Fig. 12, has horizontal rollers 7, 8 and vertical rollers 9, extra vertical rollers 10 being shown in Figs. 24 and 27. The corresponding guide tracks where the rollers are on the chain are shown at 15, 16 and 21 while 19, 20 are the links of the chain and 22 the link-connecting pins. The vertical rollers may be omitted. In the case of Fig. 24, the horizontal rollers may alternatively be omitted, Fig. 14 (not shown). In a further form, Fig. 22 (not shown), the chain has rollers 9 as in Fig. 24 and rollers 8 as in Fig. 12, cooperating with a suitable guide track. Each pair of links 19, 20 has a pair of load-supporting brackets 24 secured to them, although uni lateral supports 30, Fig. 27, may alternatively be provided. Pins 22 have rollers 23 mounted on them for engagement with the teeth of the drive sprockets 5, Figs. 26 and 27, which are synchronously driven by a driving chain 1 around sprockets 4 coupled to the pairs of sprockets 5 and a driving sprocket 2. In order to allow for uneven stretching of chain 1 the coupling between each sprocket 4 and pair of sprockets 5 consists of a driving plate 80, Fig. 32, carrying a plate 91 slidable along guides 92 by adjustment of a screw 93 mounted in extension 94 of plate 80, and a block 90 pivoted on a pin 89 carried by driven plate 81 and passing through a slot in plate 80, whereby adjustment of screw 93 effects relative rotation between the two plates, which may be locked in adjusted position by screws 86 passing into plate 81 through further slots in plate 80. In the form shown in Fig. 27, the tracks 16 and 21 are combined in upper. and lower guide members 33 and 34, the former being adjustable towards and away from the chain by rotation of a screw 42, while separate tracks 55 for the rollers 7 are also adjustable towards and away from the chain by rotation of a nut 58. Where the chain passes around sprockets 5, members 33, 34 and 55 are discontinued and replaced by fixed guides 66, 74, Fig. 27. A flanged drum, Fig. 36 (not shown), may be carried between the sprockets 5 of each pair in place of inner guide 66. A further modification, Fig. 37 (not shown), has slides carried by the chain and engaging slideways on the guide structure in place of the rollers 9 of the Fig. 16 form.
