Abstract: 977,290. Vehicle brakes. FORD MOTOR CO. Ltd. Sept. 20, 1963 [Nov. 15, 1962], No. 43162/62. Heading F2E. A motor vehicle brake control mechanism has a foot-pedal 7 and a hand control both mechanically connected to the brakes, the hand control having a ratchet 9 (not shown in detail) to hold its rod 8 in the applied position and the pedal and hand controls being interconnected so that when the pedal is moved to apply the brakes the hand control is moved similarly and both are held by the ratchet in the applied position. The mechanism is carried on a pair of spaced plates 1, 2 supported between the dashboard 3 and the floor 4. The foot pedal lever is fixed at the end of a pivot 12 carrying fixedly a U-shaped member 26 which is attached at one end 19 to a Bowden cable 20 connected to the brakes and at the other end to a link 24 which connects with an arm 29 which is fixed to a pivot 32 carrying one end of a lever 39. The ratchet 9 is of the conventional twist-release type and the rod 8 is slidable in a cylindrical casing 10 having a slot 43 cut on either side of the end remote from the handle. The end of the lever 39 passes through the slot 43 and a round-ended slot 44 in it embraces a roller 45 on an extension 42 of the rod 8 to transmit movement from the foot pedal to the hand control.
