Abstract
Abstract A device for mounting dual wheels, said device comprising a generally cylindrical member with radially projecting flanged portions at each end thereof, a plurality of apertures extending through the flanged portion at one end of said cylindrical member and positioned to receive the wheel mounting studs of a vehicle hub, and a plurality of externally threaded shafts projecting outwardly from the flanged portion at the opposite end of said cylindrical member extending parallel to the axis of said cylindrical member and positioned to mate with the mounting apertures of a vehicle wheel. Several forms of the invention are disclosed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
219 words
A device for converting a vehicle from single wheEl support to dual wheel support, said device comprising: a hollow cylindrical thin wall member formed with radially directed flange means at each end of the cylindrical member; a plurality of apertures extending through the flange means at one end of the cylindrical member, and sized, shaped and arranged to receive the wheel mounting studs of a vehicle hub comprising the original single wheel support such that said flange means become interposed between the hub and the lug nuts when secured to the studs, said apertures being equally radially spaced from the axis of the cylindrical member; a plurality of externally threaded shafts projecting parallel to the axis of the cylindrical member outwardly from the other radially directed flange means at the opposite end of the cylindrical member, the shafts being equally radially spaced from the axis of the cylindrical member a distance substantially the same as the first-mentioned radial distance to the studs to match with the mounting apertures of a second like vehicle wheel; said shafts being angularly offset in respect to the studs; a plurality of access openings in the other flange means each opening being in direct axial and angular alignment with one of said studs whereby the lug nuts may be removed by a linear tool.
Claim 2
Independent Claim
219 words
A device for converting a vehicle from single wheEl support to dual wheel support, said device comprising: a hollow cylindrical thin wall member formed with radially directed flange means at each end of the cylindrical member; a plurality of apertures extending through the flange means at one end of the cylindrical member, and sized, shaped and arranged to receive the wheel mounting studs of a vehicle hub comprising the original single wheel support such that said flange means become interposed between the hub and the lug nuts when secured to the studs, said apertures being equally radially spaced from the axis of the cylindrical member; a plurality of externally threaded shafts projecting parallel to the axis of the cylindrical member outwardly from the other radially directed flange means at the opposite end of the cylindrical member, the shafts being equally radially spaced from the axis of the cylindrical member a distance substantially the same as the first-mentioned radial distance to the studs to match with the mounting apertures of a second like vehicle wheel; said shafts being angularly offset in respect to the studs; a plurality of access openings in the other flange means each opening being in direct axial and angular alignment with one of said studs whereby the lug nuts may be removed by a linear tool.
Claim 3
Independent Claim
123 words
A device for mounting dual wheels, said device comprising: a cylindrical member formed with radially projecting flanged portions at each end thereof, a plurality of apertures extending through the flanged portion at one end of said cylindrical member and positioned to receive the wheel mounting studs of a vehicle hub, a plurality of externally threaded shafts projecting outwardly from the flanged portion at the opposite end of said cylindrical member extending parallel to the axis of said cylindrical member and positioned to mate with the mounting apertures of a vehicle wheel, a first brace secured to the exterior surface of said cylindrical member and extending arcuately outward therefrom to a bifurcated end having projections formed to engage the rim of a vehicle wheel.
Claim 4
Independent Claim
123 words
A device for mounting dual wheels, said device comprising: a cylindrical member formed with radially projecting flanged portions at each end thereof, a plurality of apertures extending through the flanged portion at one end of said cylindrical member and positioned to receive the wheel mounting studs of a vehicle hub, a plurality of externally threaded shafts projecting outwardly from the flanged portion at the opposite end of said cylindrical member extending parallel to the axis of said cylindrical member and positioned to mate with the mounting apertures of a vehicle wheel, a first brace secured to the exterior surface of said cylindrical member and extending arcuately outward therefrom to a bifurcated end having projections formed to engage the rim of a vehicle wheel.
Claim 5
Dependent Claim
39 words
The device of claim 2 further comprising: a second brace secured to approximately the midpoint of said first brace and extending arcuately outward therefrom to a bifurcated end having projections formed to engage the rim of a vehicle wheel.
Claim 6
Dependent Claim
70 words
The device of claim 3 wherein: said second brace extends in a direction generally opposite to that of said first brace whereby the bifurcated end of said first brace will engage the rim of a vehicle wheel mounted adjacent one end of said cylindrical member and the bifurcated end of said second brace will engage the rim of a vehicle wheel mounted adjacent the opposite end of said cylindrical member.
