1,229,267. Vehicle wheels. KELSEYHAYES CO. 18 Sept., 1968, No. 44453/68. Heading B7C. [Also in Division B3] To relieve stresses set up on the cooling of spot welds 13 uniting a wheel rim 12 to the circumferential flange 14 of a wheel body 11, rectilinear indentations 15 are coined in the rim 12 or flange 14 adjacent that side edge of each weld nearest the body 11. The indentations 15 may be located up to one-third of the axial width of the spot-weld in either direction from the said side edge, and they may be of wedgeshaped cross-section. The flange 14 may be discontinuous with a pair of circumferentially spaced spot-welds 13 in each section thereof, and additional coined indentations may be provided, positioned and directed as shown at 16 and 17 on Fig. 2, 23 on Fig. 7, or 29 and 30 on Fig. 8. The indentations may be formed by a coining die such as 18, Fig. 6, in handed pairs if necessary. |
