Abstract

690,872. Making crank-shafts. KNIGHT, L. F., and PITT, A. Feb. 16, 1950 [May 13, 1949], No. 3967/50. Classes 83 (ii) and 83(iv). Angular bending.-In making uniplanar crank-shafts a shaft 26 is secured at the ends by clamps 29, 30 connected in an electrical circuit to effect the heating of the shaft. The clamp 30 is then moved axially to displace a centre journal to form a crank-shaft. In the diagrammatic apparatus shown in Fig. 8 the end clamps 47, 48 are insulated and connected by links 66, 67, 53, 54 with a clamp 60 for an intermediate journal. During heating the conductivity of the clamps prevents the heating of the journals. Actuation of a hydraulic ram 63 moves the clamp 48 axially and the clamp 60 axially and transversely to form the shaft shown in Fig. 5.
