Abstract

258,629. Francis, G. March 23, 1925. No Patent granted (Sealing fee not paid). Cream separators and like machines for separating liquids from one another, or from solids, by density.-In order to provide for continuous and progressive separation the rotary member has means for effecting successive progressive reversals in the direction of flow of the fluid under treatment in a sinuous path extending towards and away from the axis of the rotary member and intersecting lines of centrifugal and gravitational forces. This sinuous path is provided by staggered perforations 25, 26 in the conical disc members 16, 17 respectively, so that the liquid in the feed receptacle 36 which is fed into the distributing member C of the rotary bowl B follows a path as shown by the arrows in Fig. 2. The member C is formed with shoulders 21 which engage recessed portions of the inner flanges of the disc members. Rings 28 of cork or other suitable material are arranged between the upper flanges 18 of the disc members to form an inner seal when the separator is used as a purifier, as in the dehydration of oil, whilst when cream is to be separated from milk the members 28 are removed and sealing members 29, similar to 28, are seated on flanges 22 of the discs, the lighter liquid being then free to pass through spaces 32 in the member C, with the inner seal removed. The cream is delivered to the outlet 27 and discharges through a spout 14, and the heavier liquid through the opening 39 and spout 13.
