538,061. Making sinks. BRIGGS MANUFACTURING CO. Jan. 16, 1940, No. 955. Convention date, Jan. 16, 1939. [Classes 83 (ii) and 83 (iv)] [Also in Group I] A combined laundry tub and sink unit is stamped in one piece from sheet metal and may have an integral splash back or a flange for mounting in a table assembly, The stamping is effected in a special sequence of operations. In the first step the deeper basin 20, Fig. 1, is drawn from the blank, and in the second step the shallower basin 21 is drawn leaving a rib 31 between them. In a modification both basins are of equal depth. Both basins are now redrawn and at the same time set down together with the rib 31 leaving a shallow offset 32 all round both basins. The drainage holes may also be punched at this time. The flange is next trimmed to the outline 62, Fig. 6, then turned up at the rear to form the splash panel, and embossing the panel 33 and producing flanges 22 and 24 follows. Next the flange 27 round the panel and sides is produced any excess metal at the corners being first trimmed off. The lower edges of the flange are retrimmed, the upper corners of the splash panel and the lower front corners of the rim are notched, and finally the flanges are inturned at 28. Holes 34 for the taps may be produced during the formation of the panel 33. In the modified form for table assembly the splash panel is omitted and the marginal flange is kept flat and provided with slots 96, Fig. 10, for fixing purposes. The dies employed in the manufacture are constructed and actuated as described in Specification 538,062.
