Abstract

205,890. Lowson, J., Challacombe, A., and Ruston & Hornsby, Ltd. July 26, 1922. Multiple-furrow ploughs; lifting- devices, power.-In an implement mounted on cranked axles, the frame is held in raised or lowered position by means of a pawl or catch on an arm or extension on one of the axles, and is lowered by gravity on the pawl being moved by a pull on a cord, and raised by locking the axle to the travelling wheel by a further pull on the cord. The spring-controlled pawl d on the arm c on the cranked land-wheel axle moves over a guide quadrant f and engages in a notch g and a recessed adjustable stop h to hold the plough in raised and lowered position respectively. The quadrant f is curved about the upper spindle a of the cranked axle. A bell-crank lever i on the arm c is linked to a spring-controlled lever m carried by a bracket on the cranked part of the axle. The operating cord or rope j is fastened to the lever i after passing round pulleys on the pawl d and spindle a. In the raised position a roller on the lever i bears against a cam z on the guide quadrant f. On pulling the rope, the pawl d is released from the notch g and the frame falls until the pawl enters the recessed stop h. On pulling the rope again, the pawl d being prevented from swinging, a tooth or pawl o on the lever m is brought into engagement with a ratchet wheel p on the land wheel and the frame is raised until the pawl d enters the notch g and the roller y engages the cam z and disengages the tooth o from the wheel p. The arm c is adjustably connected by a screwed spindle to an arm t on the furrowwheel axle. In tractor ploughs, the arm c is connected by a chain or rod u to a bell-crank lever v provided with a roller engaging the vertical spindle of the rear wheel x, so that the rear part of the plough may be raised simultaneously with the front part.
