Abstract

269,059. Koln-Lindenthaler Metallwerke Akt.-Ges. June 29, 1926, [Convention date]. Tubes. - The joints between the tubular frame members and connecting socket members of cycle frames are made by tightly fitting the frame member into the connecting sockets and then completing the joint by electric spot welding. In constructing the upper corner joint of the steering head, Fig. 1, the socket member 2, for the reception of the upper frame tube 3, only is completed, the main socket 1 for the steering head tube being left as shown in Fig. 2, so as to enable an electrode 4 to be inserted in the tube 3 for the purpose of cooperating with a second electrode 5 to effect the welding 6. The walls of the socket 1 are then bent to cylindrical shape and the adjacent edges thereof welded together, after which the steering head tube 9 is inserted in the socket formed thereby and connected to it by spot welding. The other joints of the frame are constructed in a similar manner with the exception of the connections of the tubes 23 to the crank bearing-box 17, Fig. 11, in which case the inner electrode 4 is bent at right-angles and is provided at the bead with lateral welding projections 22
