Abstract
Abstract A mounting structure for support from an implement frame and including first and second brackets supported on the frame in transversely spaced relation and the first bracket includes an anchor portion oscillatably supported therefrom for rotation about an axis extending between the brackets. The anchor portion includes structure for anchoring one end of an implement therefrom and an elongated torsion bar extends between the brackets and has one end thereof supported from the second bracket for adjustable angular positioning about the longitudinal axis of the torsion bar, the second end of the torsion bar being keyed to the anchor portion for oscillation therewith.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
297 words
A mounting structure for an implement arm, said structure including first and second stationarily supported horizontally spaced apart first and second generally parallel and horizontal tubular brackets each including opposite side walls, one of said brackets including a sleeve portion extending and journaled between the side walls thereof for oscillation relative thereto, generally aligned openings formed in the adjacent side walls of said brackets with the opening formed in the side wall of said one bracket aligned with the adjacent end of said sleeve, a torsion bar extending between said brackets and having its opposite ends rotatably received through said openings, the end of said torsion bar adjacent said sleeve being removably telescopingly keyed thereto for oscillation therewith, crank arm means carried by and projecting outwardly from the end of said torsion bar adjacent the other bracket outwardly of the corresponding side wall, adjustable means operatively connected between an outer end portion of said crank arm means and said bracket for angularly adjusting said crank arm means relative to said other bracket, said one bracket having at least one open end, said sleeve portion including an elongated tubular anchor portion extending transverse to said sleeve portion and longitudinally of said one bracket, and an implement support arm including a base end portion telescoped into and secured within the end of said tubular anchor portion adjacent the open end of said one bracket with the support arm projecting through said opEn end, the far side wall of said one bracket remote from said other bracket including an opening formed therein corresponding to the opening formed in said other bracket side wall opening and spaced along said far side wall from the first-mentioned opening formed therein and adapted to rotatably receive one end portion of a second torsion bar.
Claim 2
Dependent Claim
297 words
A mounting structure for an implement arm, said structure including first and second stationarily supported horizontally spaced apart first and second generally parallel and horizontal tubular brackets each including opposite side walls, one of said brackets including a sleeve portion extending and journaled between the side walls thereof for oscillation relative thereto, generally aligned openings formed in the adjacent side walls of said brackets with the opening formed in the side wall of said one bracket aligned with the adjacent end of said sleeve, a torsion bar extending between said brackets and having its opposite ends rotatably received through said openings, the end of said torsion bar adjacent said sleeve being removably telescopingly keyed thereto for oscillation therewith, crank arm means carried by and projecting outwardly from the end of said torsion bar adjacent the other bracket outwardly of the corresponding side wall, adjustable means operatively connected between an outer end portion of said crank arm means and said bracket for angularly adjusting said crank arm means relative to said other bracket, said one bracket having at least one open end, said sleeve portion including an elongated tubular anchor portion extending transverse to said sleeve portion and longitudinally of said one bracket, and an implement support arm including a base end portion telescoped into and secured within the end of said tubular anchor portion adjacent the open end of said one bracket with the support arm projecting through said opEn end, the far side wall of said one bracket remote from said other bracket including an opening formed therein corresponding to the opening formed in said other bracket side wall opening and spaced along said far side wall from the first-mentioned opening formed therein and adapted to rotatably receive one end portion of a second torsion bar.
Claim 3
Dependent Claim
36 words
The combination of claim 1 wherein said adjacent end of said sleeve includes a non-circular recess formed therein opening outwardly thereof, said torsion bar including a non-circular end portion axially telescoped and keyed in said recess.
Claim 4
Dependent Claim
35 words
The combination of claim 1 including aligned journal blocks supported from the inner surface portions of the side walls of said one bracket and in which the opposite ends of said sleeve are rotatably received.
