Abstract
710,879. Agricultural implements. GARNER MOBILE EQUIPMENT, Ltd. June 12, 1952 [June 15, 1951], No, 14264/51. Class 6 (1) A reversible one way plough comprises two movable plough supports and a selector mechanism adapted to lock one support in a raised position and to couple the other support for raising and lowering movement. As shown the supports comprise levers 5, 5<SP>1</SP> freely rotatable on a shaft 4 carried by a tube 1 mounted in bearers 2 and provided with actuator levers 13, 13<SP>1</SP> rigidly attached thereto. A lever 10 actuates a locking bolt 7 which selectively engages the ends 6, 6' respectively of the levers 5, 5<SP>1</SP> to hold either plough in the raised position. The lever also selectively operates an actuator bolt 14 slidably mounted in apertures in the upper ends of the levers 13, 13<SP>1</SP>, the bolt engaging in apertures 15, 15<SP>1</SP> in levers 5, 5' respectively to selectively couple either lever with the actuator levers 13, 13<SP>1</SP> for raising and lowering the selected plough by means of a crank arm which is coupled to a control lever on the tractor and oscillates tube 1. The lever 10 is actuated only when both ploughs are raised and pins 16, 16<SP>1</SP> are provided on levers 13, 13<SP>1</SP> respectively to take the load of the ploughs and free the actuator bolt for easy sliding movement. The control lever and selector lever may be operated through hydraulic or other servo mechanism and the ploughs are preferably situated between the front and rear wheels of the tractor. In a modification the bellcrank levers are connected to parallel link-work on which the ploughs are mounted.
