258,966. Shaw, W., Williamson, J. S., and Mair, H. July 6, 1925. No Patent granted (Sealing fee not paid). Shoots.-Apparatus for use in feeding stone,. ores, and other materials to crushers, conveyers or the like, arranged to control the rush of materials when tipped on to shoots from wagons, comprises a drum 1 rotating on an horizontal axis above the delivery end of a shoot 2 and carrying a set of closely-spaced independent endless chains 6 hanging loosely from the drum to form a curtain or apron obstructing the delivery end of the shoot and adapted to yield under the pressure of the material descending the shoot and gradual'y to arrest the material. The shaft 3 of the drum 1 may be driven through gearing 7 and a clutch 9 from a motor 8. In use, the material tipped' on to the shoot 2 having been arrested by the chains 6, the drum 2 is set in rotation in the direction such that the flight of the chains 6 adjacent the shoot will travel in the same direction as the material and thus sweep it into the inlet 10 of the crusher &c. The drum may be rotatable in either direction. Reference has been directed by the Comptroller to Specification 246,964.
