<p>1,113,741. Tractor power lift mechanisms. KLÍCKNER-HUMBOLDT-DEUTZ A.G. 16 July, 1965 [2 Dec., 1964], No. 30295/65. Heading A1P. The lower draft links 11 of a tractor power lift mechanism are hollow and house a shaft 12 and ovoid head 15 of a member 13 which can be withdrawn from the link in order to facilitate the coupling of an implement to the ball joint 14. The ovoid head is retained in the link by a stop 31a but allows limited omnidirectional pivoting of the part 13. In use the part 13 is held rigidly with the link 11 by means of a spring catch 18 engaging a groove 17 in the head. In an embodiment a spring- biased sliding sleeve over the draft link 11 cushions the engagement of this link with the part 13.</p> |
