Abstract

940,888. Making threaded spindles or tubes; coiling; soldering. RHEINMETALL G.m.b.H. Jan. 26, 1961, No. 3110/61. Headings B3A, B3E and B3R. A method of making threaded spindles, e.g. for jacks, comprises coiling into a spiral a strip of metal which is preformed with a longitudinal rib in such a manner that when the strip is coiled the rib constitutes a screw-thread and the remainder of the width of the strip overlaps at least one adjacent turn of the thread in the finished spiral. Steel strip 1 having a flat portion 3 and a raised rib 2 formed by stamping, rolling or pressing passes through a tinning bath and is coiled into tubular form by a heated member 4 which also serves to melt the tinned coating. The strip may be lubricated with graphite or molybdenum disulphide after tinning. The coiled strip then passes to a cooling member 5 which causes the solder to cool and set. In another embodiment, Fig. 3, additional ribs 6, 7 are formed in the strip before coiling to support the threads 2. Alternatively, Fig. 4, rolled beads 8 and reinforcements 9 are formed in the strip prior to coiling or, Fig. 5, reinforcements 11. According to another embodiment, Fig. 6, additional ribs 13 are formed and holes 15, 16, 17 which are filled with plugs of solder. Teeth 18, Fig. 8, may be formed in the strip to support the rib when the strip is coiled. The threaded spindle 20, Fig. 9, may be stiffened by an internal sleeve formed by corrugated strip 21 bent up to cylindrical form. The sleeve may be provided with a coat of solder.
