Title: Improvements relating to tractor-trailer hitches
IPC: A01D87/00
Filed: 1955-02-24
Abstract: 804,320. Tractor power-lift mechanisms. MASSEY-FERGUSON, Inc. Feb. 24. 1955. [Feb. 25, 1954], No. 5534/55. Class-79(1) In a tractor with hydraulic power lift in which the system is automatically disabled at the extreme position to prevent unnecessary pumping at excessive pressures, the coupling hook 52, Fig. 4, is raised from a lowered coupling position to a partially elevated towing position at which a coupling element 68 of the trailer engages a stop 140 when engaged for towing to prevent the links 21 from rising to the extreme disabling position so that hydraulic power is available for the operation of other machinery. In normal operation without a trailer coupling 68 engaged, the links 21 pivoted at 22 to the tractor casing are raised by a hydraulic piston 29, in: a ram 30, through a push rod 28, crank arms 25, 27 and limb 24 under the control of a lever 31. Movement of the lever 31 actuates a valve 42 through a floating lever 35 to operate the piston 29 which at its extreme movement engages projections 38 on the floating lever 35 to restore the valve 42 to neutral and disable the supply. For towing a trailer the links 21 are connected to the coupling hook 52 through links 61 on pins 73, Fig. 3, at the end of a cross-bar 71. The stop 140 limits the height by which trailer coupling element 68 is raised and thereby limits the raising of the hook 52 and link 21 and the movement of the piston 29 so that the hydraulic system is not disabled. The hook 52 is mechanically locked in the raised towing position by an upper latched link 72 connected between a pivot 89 on the tractor casing and the cross-bar 71. The link 72 comprises telescopic members 75, 76 which are automatically locked together by the engagement of spring loaded latch members 96, 97. The link 72 retains the hook 52 in position after the hydraulic pressure is released from the ram 30. For releasing the hook the hydraulic pressure is again applied and the latch member 96 released manually by movement of a handle 109. A front end loader 112, Fig. 1, may be attached to the tractor 10 and is raised and lowered in part by hydraulic rams 121 connected to draw rods 120 and in part by the hydraulic ram 30 through the links 21. The rams 121 are coupled to frames 122 which are pivoted to brackets 128 on the axle housing and are connected to the draft links through the pivot pins 73. In operation the rams 121 which are connected to the rams 30 through a check valve 132 operate first and the loader is then completely raised by the ram 30. During use of the front loader a cam pin 108 is set by a handle 109 to prevent the latch members 96, 97 from engaging and locking the links 21 in the raised position.
