856,267. Controlling motor vehicles. SCHLEPPERWERK NORDHAUSEN VEB. Oct. 24, 1958 [July 7, 1958], No. 34174/58. Class 79(5). Control gear for operating a vehicle in opposite directions comprises a pedalrigidly attached to a double lever the ends of which are linked to unidirectional-operating mechanisms. As shown in Figs. 1 and 2, pedals 3 are rigid with double levers 4 pivoted at 2, the ends of each lever 4 being connected to a lever 7 by slotted links 5. The levers 7 are attached to half shafts 10 and 11 which are rigid with segments 16 and 17 respectively and upon which are freely mounted members 14 and 15, from which vehicle - operating mechanisms are controlled. In one direction of travel, the member 14 is connected through the segment 16 to the half shaft 11, and the member 15 through the segment 17 to the half shaft 10. When the direction of travel is reversed, the segment 16 is connected to the member 15 and segment 17 is connected to member 14, the two operating positions being achieved by the provision of alternative holes 9 in each half shaft by means of which it may be connected to the lever 7. In a modification, Figs. 3 and 5, a pedal 20 is connected to a double lever 21, the ends of which are connected by ropes 25 to a rope 27 extending to the hand throttle lever 23 and to a rope 28 extending to a 'throttle control lever 30. The lever 21 is pivoted at 19 to a telescopic tower 1. The lever 30 is fixed to a hollow shaft 29 and the rope 28 passes through a hole in lever 30 and is wound upon shaft 31 passing through shaft 29. Shafts 29 and 31 are normally locked together. Operation of pedal 20 in either direction (according to the direction of travel) operates the throttle control through the levers 30 and 33. At different heights of the telescopic tower 1, the slack in rope 28 is wound upon shaft 29 by rotating this shaft relatively to shaft 30. |
