Abstract

Disclosed is a mechanism for manually shifting gears of a transmission from a remote operating station control lever. The mechanism features a rotatable slideable member having a protuberance that extends through an opening in the transmission casing and is adapted to move rail members within the transmission for engaging the gear combinations desired. The slideable member is preferably connected to the control lever by flexible cables such that movement of the lever along one axis causes the slideable member to rotate so as to position the protuberance adjacent the rail member desired. In one embodiment the slideable member is pivotally mounted to a rotatable member which is preferably connected to the control lever by a flexible cable such that movement of the control lever along a different axis causes the rotatable member to rotate which causes the slideable member to slide along a defined path and move the rail member to which the protuberance is adjacent. In another embodiment, the cables or other connecting means connected between the control lever and the slideable member are used to both rotate and slide the slideable member along a defined path to cause the protuberance to impinge upon and move the rail member to effect the gear combination desired.
