Title: Improvements in Motor Driven Rotary Ploughs or Cultivators.
Inventor: MAILLET JOANNY
IPC: A01B33/02
Filed: 1916-04-15
Abstract: 100,314. Maillet, J. April 17, 1915, [Convention date]. Motor implements; propelling implements; steering implements; adjusting parts of implements; ploughs; cultivators. -The shaft of the ploughing or tilling apparatus of an agricultural machine is driven from a motor through a train of gearing containing a speed-changing gear, and the same train is used to impart motion to the driving wheels, a second and supplementary speed-changing mechanism being arranged in the connexions to the driving- wheels. The motor 2, Fig. 2, operates, through a two-speed gear A, B, a shaft 5. which drives a countershaft 8 carrying at its end a sprocket-wheel 27, from which the axle 35 of the tilling-tools is driven. The shaft 8 is connected through a variable gearing C, D, with a shaft 11 carrying a pinion 12, which gears with a wheel 13 on the driving-wheel 15. The hub of the wheel 15 is offset outwardly, thus permitting the engagement of the wheels 12, 13 to take place as near as possible to the centre of the wheel. The change-speed gears are independently operated. A steering-wheel 28 operated by a worm rod 30 is arranged practically in the plane of the driving-wheel 15. A supporting-wheel 18 is mounted on a bracket 17 carried by the axle 16 of the driving-wheel, the mounting being shown in Fig. 4. The bracket, which may be adjusted laterally of the axle by bolts passing through holes 23, is provided with a journal 19 which carries an eccentric disk 20. This disk, which may be rotated to vary the height of the supporting-wheel by means of a hand-lever 25, is provided with a peripheral race for the rollers 21, upon which the hub 22 of the wheel 18 turns. The tilling- apparatus is pivoted to the main carriage by two arms 33. In the form shown, the tilling- apparatus comprises a cast-metal core 35 with threads 36, to which are riveted screw-thread sections 37 connected by riveted or bolted plates 38. The ends of the sections are stated to give a saw tooth 39 at each join. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification, in which two driving-wheels are used, connected by a shaft which is driven at its centre through a ball-and-socket hub. The bearings for the axle of the wheel support the weight of the frame through vertical springs, and their lateral movement is controlled for steering purposes by springs and rods operated by levers on the handles of the machine. A spring- cushioned shoe at the end of the machine regulates the depth of working. This subject-matter does not appear in the Specification as accepted.
