Abstract

689,151. Mixing appliances. FARRELBIRMINGHAM CO.. Inc. May 29, 1951 [July 31, 1950], No. 12556/51. Class 86 'In a mixer of the Banbury type the closure 17 for the bottom discharge opening 16 is formed on its upper side by two plane surfaces 33, 34 which converge upwardly to a ridge 35 lying in the central plane of the machine parallel to the axes of the rotors 15 at a level considerably below the plane containing said axes. The end walls of the machine are formed with correspondingly V-shaped openings the edges 31, 32 of which fit closely against the surfaces 33. 34. The closure member is slidably operated by fluid pressure admitted into the cylinder 18 in which it acts against a piston fixed relatively to the frame of the machine.
