519,680. Strainers; making gratings. WALKER, J. Sept. 22, 1938, No. 27603. [Class 46] [Also in Group XXII] Plates for straining paper pulp or other liquor are made of corrugated sheet metal with slits D, Fig. 9, cut along the apices of the corrugations. The corrugations may be angular or curved. When the slits become too wide, on account of wearing, the corrugations may be squeezed together and the slits re-cut. Figs. 11 and 12 show forms of strainer plate in which there are also parallel slits between the corrugations. When building up drums or trough strainers of a number of plates, adjacent plates can be joined as shown in Fig. 5, by laying their edges on a side bar E, with packing strips e, e' of lead above and below and a clamping strip F riveted to the bar.
