921,412. Clutch control. GENERAL MOTORS CORPORATION. Dec. 6, 1961 [Dec. 22, 1960], No. 43682/61. Classes 80 (2) and 80 (3). The operating rod 70 of a clutch 64 is connected to a depending lever 21 carrying the pedal 22 by a control toggle linkage mounted on the lever pivot 18 and having an arm 33 pivoted to the upper end of a rod 36 whose lower end is connected to a link 63 pivoted at 76 and connected at 80 to the rod 70. The arms 21, 33 are integral with a first toggle link 37 connected at 41 to a second toggle link 47 connected by a control link 46 to a member 32 also carried by the pivot 18. In the clutchengaged position shown a tension spring 51 between pivot 18 and the pivot 48 of links 46, 47 holds the end of toggle link 37 against an abutment formed by the pivot 42 connecting members 32, 46, and as the arm 21 is moved for disengagement links 37, 47 are first straightened against the force of spring 51, but as the dead centre is passed the spring assists the disengaging movement. The mechanism may be adjusted by releasing a bolt 44 and rotating the control linkage about pivot 18, the spring 51 serving to maintain the link 37 against pin 42 so that the toggle setting is not altered. A modified arrangement, Fig. 8, comprises first and second toggle links 109, 123 loaded by a spring 116, and members 117, 124 corresponding with members 32, 46. |
