Abstract

108,674. Mascart, C. Aug. 7, 1916, [Convention date]. Flat endless-band elevators; auxiliary belts; driving-gear; feeding-devices; idler rollers and idler drums; tensioning; troughing rollers.-An elevator comprises two travelling bands 1, 10, Fig. 1, which grip the material raised between them. The tension of the band 1 is maintained constant under all atmospheric conditions by adjusting the weights 8, or varying the tension of a spring, and the tension of the band 10 can be regulated by adjustment of the drum 13 by means of sliding bearings moved by screws. The band 1 is driven by a motor 2<1>, and the band 10 is driven by the friction between it and the band 1 and the material to be transported. The band is supported by rollers 11, or fixed transverse guides, and its edges are curved inwardly either by rollers 12 or fixed angle members 16, Fig. 3. If it is desired to raise heavy materials, the band 10 may be pressed against the band 1 by curved rollers 15 carried by a frame which is forced downwards by springs 15<1>, 15<2> or by a weight. The passage of the materials below the drum 9 is facilitated by mounting the drum on a movable frame held in place by springs or weights, and, if necessary, the drum 2 is mounted in a similar manner. The pressing and supporting rollers are formed with holes 30, Fig. 8, so that any material which is carried between the band and roller can pass through, and fall through the ends 31. In a modification, the drum is composed of bars mounted in perforated disks. The elevator may be fed by a dredger device driven by the drum. The Specification as open to inspection under Sect. 91 (3) (a) states that the band 10 may be driven by the motor 2<1>, or by a separate motor enclosed in or driving the drum 13. This subject-matter does not appear in the Specification as accepted.
