    • 7327. Reed, M. H. March 23. Moving - container apparatus; discharging- appliances.-Relates to rotary concrete and like mixers of the type in which the materials are fed into the drum over a low annular flange at the receiving end and passed into the drum by blades, and to discharging-devices for the same. Near to the receiving-end of the drum is a partition 7, through openings 9 in which materials fed into the drum over the flange 3 are lifted by blades 10. Other blades 11 prevent materials from passing back from the drum through the openings 9. The materials are mixed by blades 12, 13 and discharged by the shoot 14. The shoot 14 is provided with a hinged cover 15 operated by a spindle 16 passing through the drum and provided with handles at each end. A spring 19 is arranged so as to hold the cover 15 either fully open or close shut. A modification is described in which the partition 7 is dispensed with and the blades 10, 11 united and modified accordingly. In a second modification, shown in Fig. 10, the end of the drum is surrounded by an annular pocket 31, out of which the materials are lifted by the blades 10 , thus allowing the drum to be fed at a lower level.
