Abstract
Free-play restraining apparatus for a three-point implement hitch, comprising a pair of adjustable, slideway-acting planar uprights mounted to the implement frame adjacent the hitch arms. Length adjustable fore and aft stops mounted to contact each clamp plate and multiple length adjustable stops mounted to each upright and contacting the vehicle frame, along with lubrication fittings opening to the slideway surface, provide a lubricated coplanar slidway restraint.
Claims6
Apparatus for stabilizing a vehicle-mounted implement hitch having a pair of hitch arms capable of being raised and lowered and each exhibiting side-to-side sway comprising:
- (a) first and second upright planar members, vertically supported from a bottom edge and having a pair of vertically disposed threaded weldments extending downward on opposite sides of respective first and second laterally extending, horizontal mounting plates rigidly secured to the vehicle frame and wherein the spacing between the pairs of threaded weldments is greater than the width of said first and second mounting plates to permit the horizontal rotation of each planar member;
- (b) first and second clamp plates respectively receiving the pairs of threaded weldments of said first and second planar members and means mounting to said threaded weldments for compressively drawing each upright planar member and clamp plate to its mounting plate;
- and
- (c) length adjustable stop means for adjustably supporting an upper and a lower end of each upright planar member relative to the vehicle and its associated mounting plate to bring each upright planar member into planar parallel relation to each hitch arm at an outer sway extreme whereby each hitch arm slidably contacts one of said upright planar members as it is raised and lowered.
Apparatus for stabilizing an implement hitch including at least one hitch restrained at one end to a supporting vehicle and wherein said arm is capable of being raised and lowered and exhibits inherent side-to-side sway comprising:
- (a) at least one upright planar member having a bottom edge supported on a laterally extending mounting plate rigidly secured to the vehicle frame and a vertical surface in contact with said hitch arm;
- (b) means for compressively coupling said upright planar member to said mounting plate such that said vertical surface may horizontally rotated into planar parallel relation to the contacting surface of said hitch arm;
- and
- (c) at least one length adjustable stop means extending between said upright planar member and the vehicle frame for restraining movement of said upright planar member once positioned relative to said hitch arm.
