Abstract

294,152. Elias, J. J. M. July 18, 1927, [Convention date]. Cutting sugar cane etc.; disc tool implements with adjustable tool frames; tools; travelling and propelling gear. - Sugarcanes or similar crops are guided between two lateral dividers 1 having inclined upper edges from which upper edges rotary cutters 2 project to cut off stems lifted by and moving upwards along the dividers. Lifting members for the roots are situated between the dividers. The harvesting appliance is adjustably mounted in a frame of girders 14, 15 adapted to be secured to a motor tractor. To bend over the cane and to cut off the tops a curved ladder 16 is secured to the front of the machine, its lower end being pivotally secured to the girders and its upper end to an adjustable frame 17 having a forwardly projecting comb 18 that is maintained horizontal. The frame 17 carries two sets of rotary saws 20 driven from the motor to cut off the tops engaged by the fingers of the comb, such fingers being provided with knife edges 19. According to the Specification as open to inspection under Sect. 91 (3) (a) the lifting members comprise coulters 3, 4, Fig. 4, (Cancelled) provided on their inner sides with inclined detachable guide plates 5, and also a hoeing blade 6 secured to a horizontal bar 7 attached to the coulters. A transverse shaft 10 arranged behind and above the bar 7 is fitted with a number of discs 11 to break up lumps of earth lifted by the lifting members. The coulters may be replaced by flat knives 12, 13, Fig. 3 (Cancelled) when it is desired to cut off the cane below the surface instead of lifting the roots bodily. The appliance may be combined with cover plates for the wheels or endless-track devices of the tractor, or such cover plates may be fitted separately. The cover plates may be vertically adjustable. This subject-matter does not appear in the Specification as accepted.
