Abstract
1,199,315. Change-speed gear control means. INTERNATIONAL HARVESTER CO. OF GREAT BRITAIN Ltd. 19 Sept., 1967, No. 42519/67. Heading F2D. A crawler tractor has a lever 1 controlling hydraulically operated forward and reverse clutches and which is returned to neutral and locked in this position by locking means which blocks the exit from the operator’s cab when not in its locking position. The control lever 1 is pivoted about an axis 2 and has a pin 10 engageable by a locking member 13 which is pivoted at 12 and fast with an operating handle 18. On moving the handle 18 to its locking position, if the lever 1 is in its forward or reverse position, a cam surface 14 or 15 of the member 13 engages the pin 10 and shifts the lever to its neutral position in which a slot 16 engages the pin 10 to lock the lever 1.
