Abstract
Abstract An assembly for mounting dual wheels, said assembly comprising a generally cylindrical member with outwardly radially projecting flanged portions at each end thereof, a plurality of apertures extending through the flanged portion at the inner 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 outer 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. Radially projecting arms are diagonally adjustable by a plate-bolt assembly associated with the outer flange such that the arms when secured transfer at least some of the load from the outer hub of the dual wheels to the rim of the inner wheel.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
152 words
An apparatus for mounting dual wheels, said apparatus 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 to support a first vehicle wheel; 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 second vehicle wheel; and an adjustable load-transferring mechanism comprising a plurality of arms extending from the cylindrical member, means mounting each arm to the cylindrical member for movement in respect thereto until the distal end of each arm engages the rim of the first vehicle wheel and means for releasably anchoring said arms in said rim-engaging position.
Claim 2
Independent Claim
152 words
An apparatus for mounting dual wheels, said apparatus 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 to support a first vehicle wheel; 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 second vehicle wheel; and an adjustable load-transferring mechanism comprising a plurality of arms extending from the cylindrical member, means mounting each arm to the cylindrical member for movement in respect thereto until the distal end of each arm engages the rim of the first vehicle wheel and means for releasably anchoring said arms in said rim-engaging position.
Claim 3
Dependent Claim
21 words
The apparatus of claim 1 wherein: said shafts are rotationally offset from said apertures about the axis of said cylindrical member.
Claim 4
Dependent Claim
34 words
The apparatus of claim 2 further comprising: a plurality of recesses formed in said flanged portion at the opposite end of said cylindrical member interposed between said shafts and generally aligned with said apertures.
Claim 5
Dependent Claim
54 words
The apparatus of claim 1 wherein said one flanged portion comprises: a plurality of arc segments spaced about the periphery of said cylindrical members; notches in the cylindrical member adjacent said arc segments for access to said vehicle hub; and support structure bridging between the cylindrical member and each arc segment across the notches.
Claim 6
Dependent Claim
138 words
The apparatus of claim 1 wherein said mounting means of the adjustable mechanism comPrises a pin eccentrically passing through each arm, the shorter length of arm in respect to the pin passing through an elongated slot in the cylindrical member and the longer length extending radially and diagonally outward away from the cylindrical member, each pin being confined in a channel, the channel and slot permitting axial displacement of the associated pin and arm and rotation of the arm about the pin and wherein said releasable anchoring means comprise a plate interior of the cylindrical member upon which the proximal end of each arm is adapted to engage and means for adjustably displacing the plate until the distal end of each arm firmly engages said wheel rim and for holding said plate once so displaced against inadvertent displacement.
