Abstract: 1,273,251. Filters. CARBORUNDUM CO. 2 May, 1969, No. 22422/69. Heading BID. A sleeve-like filter element (16) of sheet material is constrained to pleated shape by having its ends clamped against outwardly extending cogs 22, 24 of a core 12 by respective segmented clamping rings 40, 42 which present inwardly extending cogs 52, 54, fitting between cogs 22, 24 (Fig. 1, not shown). The two ends of the core are joined by posts 38, and the rings 40, 42 may be similarly joined by ribs 44 or separate. Core and rings are moulded of polypropylene, and the segments of the rings in Fig. 3 are connected by integral, flexible straps 58. The rings open out (Fig. 5, not shown) to facilitate replacing the element (16), and their mating ends are secured by catch 78 or by an enclosing wire clamp (76) (Fig. 1, not shown). In Fig. 1, clamp (76) encircles axial extensions 52 of the ring, but in Fig. 10 (not shown) radial extensions support the clamp (76) around but clear of straps 58. Fig. 8 (not shown) illustrates non- integral straps (96), and in Figs. 7, 9 (not shown) ring segments are hinged together by pins (90) in slots (92). Figs. 11 to 13 (not shown) illustrate sealing the ends of the filter element between pairs of concentric gaskets or by integral rubber mouldings.
