Abstract

1348191 Fusion welding; making hand tools PEAR TREE TOOLS Ltd 26 Jan 1973 [11 Jan 1972] 1155/72 Headings B3R and B3A [Also in Divisions B4 and E1] In a method of manufacturing a hand tool such as a scraper, putty knife, wood chisel, trowel or plasterers float, a tang, shank or socket for a handle is attached to a blade portion of the tool by MIG shielded arc welding. The blade portion 10 (Fig. 1) of a scraper, putty or filling knife is pressed out of hardened and tempered steel strip and then taper ground. A separate mild steel tang portion 12 (Fig. 2) is also formed by pressing, is then folded above the dotted line A to form a bolster for the handle and the tab 11 of the blade portion is inserted through slot 15 to lie in the slot 13. MIG shielded arc welding is then carried out to secure the tab 11 to the tang 12 and the weld dressed if necessary by grinding. The tabs 14 are folded over to complete the bolster 16 (Fig. 5) and the tang is subsequently drilled for wooden or plastic stiles to be attached thereto or a plastics handle moulded thereon. In a method of manufacturing a plasterers float (Fig. 9) the blade portion 32 is attached by a series of spot welds 33 to weldable MS inserts 31 in a light alloy handle bracket or tang 30. Figs. 7 and 8 (not shown) illustrate the method as applied to the manufacture of a chisel.
