Title: Improvements in or relating to electric arc welding
IPC: B23K9/035
Filed: 1949-01-24
Abstract: 659,900. Uniting by fusion. GENERAL ELECTRIC CO., Ltd., and DONELAN, J. A. Jan. 24, 1949, No. 1898. [Class 83 (iv)] A method of electric arc welding, without the use of a filler, the abutting edges of two metal strips, sheets or the like comprises backing up the seam end with bridging means of electrically and heat conducting material from or to which the arc is transferred to or from the seam so that there is substantially no discontinuity in the arcing conditions and the rate of heat transfer away from the arc. In an embodiment two metal strips 1 have their ends pressed together and clamped on a platform 2 by the clamping plates 9, a channel (not shown) being provided in the platform beneath the joint. The platform and an electrode 3 are connected to an electricity supply. Bridging tabs 8 of the same material and gauge as the strips 1 (e.g. aluminium) are clamped in movable blocks 10 and pressed against the edges of the strips to bridge the joint. The tabs may have a convex edge or a projection so that the ends away from the seam do not contact the sides of the strip. Each tab may be in two parts having a join along the line of the seam. The tabs may be forced towards the joint by peening. To weld the strips together the arc is started on one tab and transversed across the joint by means of an electric motor 6 and gearing 7 to the other tab, so forming a welded seam 11. The tabs are then broken off, leaving the sides of the strips continuous. A clamping jig for use under this method comprises a frame 12 having rods 13 supporting adjustable strip guiding posts 14 having notched wear-resisting tips. Each strip rests on adjustable stepped plates 17 which are connected beneath the frame 12 to plates 18 which through a rotatable double threaded spindle 20 permit adjustment of the plates 17 for clamping the strip. The strips are held down on the plates 17 by quick-release clamping means comprising a plate 22 and an arm 24 hinged at 25 and carrying a quick-release handle 26. The seam to be welded lies over a heat-resisting metal plate 29. The tabs are held in blocks 31 guided in the frame 12 and having undercut upstanding pillars 32, each block being threaded onto a double-threaded spindle 33 rotatable by a knob 34 for clamping the tabs against the sides of the strip. The seam of a tube may be welded by this method.

Abstract: 393,895. Binding manifolding &c. pads. BOHMERT, W. C., Mamaroneck, New York, U.S.A. Jan. 20, 1933, No. 1986. [Class 16.] In a pad or assembly of sheets, especially a manifolding pad for use in a typewriter, the corresponding ends of alternate sheets are irregular in outline, so that the applied adhesive adheres to parts of the faces of the adjacent sheets as well as to the edges. The original sheets 1, 3 are provided with scalloped edges 4, and alternate manifolding sheets 2 with straight edges. The adhesive 5 is applied with a brush in the ordinary manner and penetrates into the scallops 4 and adheres to the surfaces of the sheets 2 as well as to the lengthened edges of the sheets 1, 3, thus providing a more secure binding. The sheets 1, 3 may have their lower right-hand corners removed and the sheets 2 their upper left-hand corners, so that by gripping the corners all the sheets 2 can be pulled at once out of the assembly, leaving the sheets 1, 3 still united. The sheets 1 and 3 may have a line of perforations part way down to permit removal of the lower parts.
