Dual wheel assembly for tractors

Claim 2

In apparatus for securing a rim of a dual wheel to a rim of a tractor wheel, the improvement comprising: a plurality of attaching means spaced about said tractor wheel; a plurality of generally U-shaped bracket means fixed to the interior of said dual wheel, each bracket providing a curved bearing surface, said bracket means being spaced at different angular intervals than the angular spacing of said attaching means, each bracket further defining a generally T-shaped slot including a base portion communicating through an edge of said curved bearing surface and a laterally elongated portion communicating with said base slot portion; a plurality of fastener means for securing associated ones of said attaching means and said bracket means, some of said attaching means being offset clockwise relative to said bracket means and some of said attaching means being offset counterclockwise relative to their associated bracket means; and a plurality of adjustment means, one for each fastener means, each adjustment means including a first adjusting member having a bearing surface curved to permit adjustment to achieve offset alignment, said curved surface of said first adjusting member engaging said curved bearing surface of an associated bracket means, a second adjusting member having a curved surface for permitting adjustment of said fastener in a radial direction of said tractor wheel, said curved surfaces of said first and second adjusting members facing opposite directions.

Claim 3

The apparatus of claim 1 further comprising means for coupling said first and second adjusting members together to prevent relative rotation between them.

Claim 4

The apparatus of claim 1 wherein said brackets are fixed to the rim of said dual wheel spaced inwardly adjacent said tractor wheel.

Claim 5

The apparatus of claim 1 wherein said brackets are fixed to the rim of said dual wheel spaced outwardly away from said tractor wheel.

Claim 6

In apparatus for securing a rim of a dual wheel to a rim of a tractor wheel, the combination comprising: a plurality of attaching means secured to and angularly spaced about said tractor wheel; a plurality of generally U-shaped bracket means fixed to the interior surface of said dual rim, each bracket means including a center wall defining a curved bearing surface and first and second support walls extending outwardly of said center wall and toward said tractor wheel when said dual wheel is assembled thereto, said bracket means being spaced about said dual rim at different angular spacings than said attaching means are spaced about said tractor wheel rim, each of said bracket means including a T-shaped slot including an elongated transverse portion for receiving an associated fastener and a base portion extending upwardly thereof through said center wall; a plurality of fastener means for securing associated ones of said attaching means and said bracket means, each of said fastener means comprising a hook adapted to couple to an associated eye-nut, an elongated shaft extending from said hook for being received in an associated slot of a bracket means, and a nut threadedly received on the distal end of said shaft, some of said attaching means being offset clockwise relative to associated ones of said bracket means, and some of said attaching means being offset counterclockwise relative to their associated bracket means; and a plurality of adjustment means, one for each bracket means to which is secured an offset fastener means, said adjusting means permitting offset alignment of said fastener means relative to a line parallel to the axis of the tractor drive axle and comprising a first member having a cross section of general D shape and including a curved bearing surface engaging the bearing surface of an associated bracket means in assembled relation and defining a tapered aperture for receiving an associated fastener means, and a second D-shaped adjusting member interposed between said nut and said first adjusting member and coupled to said first adjusting member to prevent relative rotation therebetween, said second adjusting member further defining a surface curved about a line transverse of the line of curvature of said first adjusting member to permit said fastener means to be adjusted radially of said tractor wheel to accommodate the same to different spacings of said eye-nuts on said tractor wheel.

Claim 7

In apparatus for securing a rim of a dual wheel to a rim of a tractor wheel, the combination comprising: a plurality of attaching means secured to and angularly spaced about said tractor wheel; a plurality of generally U-shaped bracket means fixed to the interior surface of said dual rim, each bracket means including a center wall defining a curved bearing surface and first and second support walls extending outwardly of said center wall and toward said tractor wheel when said dual wheel is assembled thereto, said bracket means being spaced about said dual rim at different angular spacings than said attaching means are spaced about said tractor wheel rim, each of said bracket means including a T-shaped slot including an elongated transverse portion for receiving an associated fastener and a base portion extending upwardly thereof through said center wall; a plurality of fastener means for securing associated ones of said attaching means and said bracket means, each of said fastener means comprising a hook adapted to couple to an associated eye-nut, an elongated shaft extending from said hook for being received in an associated slot of a bracket means, and a nut threadedly received on the distal end of said shaft, some of said attaching means being offset clockwise relative to associated ones of said bracket means, and some of said attaching means being offset counterclockwise relative to their associated bracket means; and a plurality of adjustment means, one for each bracket means to which is secured an offset fastener means, said adjusting means permitting offset alignment of said fastener means relative to a line parallel to the axis of the tractor drive axle and comprising a first member having a cross section of general D shape and including a curved bearing surface engaging the bearing surface of an associated bracket means in assembled relation and defining a tapered aperture for receiving an associated fastener means, and a second D-shaped adjusting member interposed between said nut and said first adjusting member and coupled to said first adjusting member to prevent relative rotation therebetween, said second adjusting member further defining a surface curved about a line transverse of the line of curvature of said first adjusting member to permit said fastener means to be adjusted radially of said tractor wheel to accommodate the same to different spacings of said eye-nuts on said tractor wheel.
