Abstract: 735,076. Making wheel hubs. LOO, H. VAN DE, and DREISER, O. Feb. 17, 1953, No. 4349/53. Classes 83 (2) and 83 (4). Forging, jointing.-A wheel hub preferably for a bicycle wheel, has a pair of spoke attachment flanges 2 connected together by a hub sleeve 4, such flange being formed integral with the ball-bearing race shell 1 from a circular blank having a central hole by a cold pressing operation which increases the density of the material in the region of the bearing shell 1 and thickens or extends the wall about the hole in the axial direction thereof. The shells are pressed by a pair of complementary dies of which the lower die has a conical pin to form a conical bore 15, Fig. 4. The bore 15 is then machined to provide splines 5 therein, the holes for the spokes are drilled, and the shell is then hardened. The ends of the sleeve 4 may be splined to correspond with the splines 5 or alternatively they may be left unsplined and pressed into the splined bore which cuts into the sleeve ends and thus effects a secure joint. A shoulder 6 limits the insertion of the sleeve in the bore and an annular recess 9 in the bore receives the shavings cut from the sleeve during the pressing operation so that these shavings will not be visible in the assembled hub. In another embodiment, Fig. 1 (not shown), the shells are formed with externally splined spigots which are pressed into the bore of the sleeve 4. The spigots are formed by extrusion during the pressing operation. The shells and sleeve may alternatively be bonded together by a cold setting or thermoplastic resin.
