    Abstract: 662,891. Rotary filters. KOMLINESANDERSON ENGINEERING CORPORATION. May 23, 1949 [June 11, 1948], No. 13756/49. Class 46 A filter web for a rotary drum filter comprises a plurality of parallel, contiguous, flexible filaments each constructed of a series of non-pervious elements spring- biassed closely together along the longitudinal filament axis, the spacings between the elements being controlled by tension applied along the said filament axis. As shown at 15a, Fig. 4, the elements consist of coils or turns of a helical spring, or as shown in Fig. 5, of discs or washers 36, threaded on a spring 35 so as to be biassed together along the filament axis . The elements may also consist of rings spring- biassed together. The discs or washers 36 are given slight deformations 37 to provide a minimum spacing for filtration. The filaments 15a consist of a plurality of helical metal springs made continuous by short connecting studs 27, Fig. 3, which threadedly engage the interior of the spring and at the same time form baffles to prevent the passage of liquid longitudinally through the filaments. The filaments are made endless by set studs 27 and so also the spring support 35, Fig.. 5. Half round wire is preferably used to form the helical spring shown in Fig. 4. The filaments 15, Fig. 2, on the drum 10 lie in the same horizontal plane, each filament being contiguous with the adjacent filament, the end filaments resting on inclined sealing rings 25 rigidly attached to the drum heads 26 to compensate for errors in filament diameters. The filaments 15a, Fig. 3, are placed over the .drum 10 and some at least are passed off the drum and over a discharge roller 16.
