Abstract

685,940. Change-speed control. NAYLOR, J. T., and ATKINSON LORRIES (1933), Ltd. June 22, 1951 [May 20, 1950], No. 12675/50. Class 80 (ii). A forward control gear-shift lever 9 on a commercial vehicle slides and turns a gear-actuating shaft 7 by engagement of its flattened lower end 9 in an axia slot 10 in the shaft. The lever fulcrums between hardened transverse pins 8 in an oil-filled casing 5 and its lower extremity 9a moves over a fixed base plate 11 having a stepped rib 22, 23 over which the lever 9 must be lifted to different levels before the lever can be moved laterally into the channel for selecting low (position B) or reverse (C), such lift being opposed by a tension spring 20 biasing the lever downwards and also laterally to neutral (A). Three other forward speeds (axial positions D, E) are reached without lifting. Outward pull on the lever 9 is limited by abutment against the fulcrum pins 8 of sideplates 16 bolted to the lever and carrying rattlepreventing resilient pads 18. Hardened transverse pins 12 form the axial boundaries of the shaft slot 10.
