1,118,848. Change speed control. PUBLICITE FRANCAISE. 30 Jan., 1967 [1 Feb., 1966], No. 4394/67. Heading F2D. A floor-mounted gear-shift control in an automobile having a' transverse engine and gear-box, comprises a shift lever 1 ballpivoted at 3 on a floor-carried support 4, and a block 5 engaged by the end 3a of the shift lever and so connected to cross-shift and gear-establishing levers f, h of the gear-box that rotation and axial movement of the block about and along a fixed longitudinal axis Z-Z respectively effects crossshift and gear-establishment. The cross-shift lever f is fixed to a shaft 15 and acts to translate the gear-establishing lever h which is slidably keyed on a shaft g. As shown, the block 5 is slidable but non-rotatable with respact to a rotatable tube 6, the block and tube having complementary surfaces 6, 7, and is fast with a shaft 16 journalled and slidable in the tube 6. Rotation of the block 5 and tube 6 by transverse shift lever movement F rotates the cross-shift lever f through an arm 11 carried by the tube, a pin-and-slot connection 12, 13, and an arm 14 fast on the shaft 15. Axial movement of the block 5 by longitudinal shift lever movement G rotates the gearestablishing lever h through the shaft 16, collars 18 on the shaft 16, a forked lever 19, 20, 22, a link 23, and an arm 24 keyed on the shaft g. A 1-4 and R change-speed grid diagram is marked on the support 4. In Fig. 2 (not shown), the pin-and-slot connection 12, 13 is replaced by a transverse connecting link (12a), and one or two elastically yieldable bias means acting on the block 5 or any other movable cross-shift means are provided to produce a return to the III-IV shift plane and/or a stiffness in cross-shift to Reverse. Such bias means may comprise one or two springs (26a) connected to act on the arm 11, or one or two screw-adjustable, spring-loaded plungers (25) supported in the wall of the support 4 and acting on the sides of the block 5. In Fig. 4 (not shown), the hollow tube 6 is dispensed with, and the arm 11 is fast on the shaft 16 and connected to the arm 14 by the connecting link (12a) of Fig. 2 (not shown), the connecting link (12a) accommodating axial movement of the shaft 16 during gear-establishment. |
