Abstract

2340. Fiddes, W. J. Feb. 13. Discharging-devices for endless-belt conveyers; screw - conveyers. - In an apparatus for charging retorts &c. or for conveying coal, grain, ores, &c., of the kind in which the material is forced along a discharge conduit 1 movable lengthways, relatively to the feeding- means, such as an endless belt or screw-conveyer, the conduit is actuated by one or more pairs of chains 17 placed side by side and adapted when extended to form a rigid rod. As shown in connexion with a charging and discharging machine for gas-retorts, the conduit 1 comprises a series of telescopic tubes, mounted by rollers 3 on a rail track 8, which can be raised or lowered to the height of the retort by ropes 41 passing round pulleys 43 and winding- drums 44. The conduit is guided, when in the retort, by side rollers 4. Coal is supplied from an overhead hopper 36 through a telescopic shoot 37, and is forced through the conduit 1 by any suitable thrusting-device, for example a plunger, endless conveyer, or, as shown, by a screw 11, on the shaft of which is mounted a fly-wheel 14. The pusher-chains 17 are secured to the outermost section of the conduit and pass round sprockets 16, 23, 25, their rear ends being continued by wire ropes 27, which are finally wound on to drums 29 mounted on the same shafts as the sprockets 16. The shafts carrying the sprockets 16 are geared together as shown, and one of them is driven from the shaft 33 through a clutch 35 and bevel-gearing. The outermost section of the conduit carries a pivoted flap 6 and a pusher head 7 for discharging the retort. The chains 17 are formed of block links 18, Fig. 4, having jointing-ears 22 and hollows 19 for the teeth of the driving-sprockets.
