The present invention comprises a series of important improvements on an apparatus described by Mr. Yaryan in a former English patent, No. 14,162 (1886), and covers a number of important modifications in construction, whereby improved results are secured. It is only necessary, therefore, to give the details of the new patent, No. 213 (1888), since it embodies the latest improvements which practical working of the apparatus has suggested. In reference to the accompanying illustrations the following details are given: Fig. 66 represents a side elevation of the apparatus; Fig. 67, the front elevation; Fig. 68, a top plan view; Fig. 69, a vertical section of a cylinder showing the evaporating coils and separating chamber; Fig. 70 is a horizontal section; and Fig. 71, a vertical section of the separating chamber shown in Fig. 69, both on reduced scale; Fig. 72 is a broken section of the cylinders for showing the connections of the liquid pipe from the first to the third effect evaporator; Fig. 73 is a rear end view of a cylinder with manifold, the feed pump and a sectional view of the feed box and supply devices; Fig. 74 represents a sectional view, on enlarged scale, of the manifold and a feed duct; Fig. 75 is an inside view of a return bend-head; Fig. 76 an inside view of a section of the head; Fig. 77, a vertical cross section thereof on enlarged scale, and showing the partitions forming cells for connecting the ends of the evaporating tubes; Fig. 78 is a vertical longitudinal section of a catch-all chamber; Fig. 79, a cross section thereof; Fig. 80 is a vertical longitudinal section of new form of separating chamber; and Fig. 81 represents a side view and Fig. 82 an end view of the cylinders for showing the pipe connection between the separating chambers of the third and fourth effect evaporators.
