Abstract
9678. Quigley, W. S. Aug. 13, 1914, [Convention date]. Feeding-devices for granular and like matemals.-In apparatus for feeding pulverulent fuel and other material, of the kind in which a current of air picks up and delivers part of the material fed from the source of supply, while the surplus material is returned to the source, the air current is supplied through a hollow screw conveyer which feeds the material from the source of supply, and the surplus material is returned to the source by a screw conveyer arranged concentrically with or below the feed-screw. As shown in Fig. 1, fuel &c. is fed by the screw 3 from a hopper 1 through the central bore 8 of a concentric screw 6. The screws 3, 6 are of opposite pitch, but revolve in the same direction, being driven by inter-connected gear-wheels 21, 15. Air blast passes through the bore 5 of the screw 3 and delivers part of the fuel &c. through the discharge pipe 14, the surplus being returned to the hopper by the screw 6. The spokes 16 of the gear-wheel are rhomboidal in section and inclined to the same pitch as the screw 6. In the modification shown in Fig. 6, the fuel &c. is fed from the hopper by the hollow screw 33 through the conduit 42, and part is delivered by the blast passing through the screw to the discharge conduit 44. The surplus fuel &c. enters the chamber 40 and is returned to the hopper by the screw 36.
