Abstract
Abstract An improved dual wheel construction includes a first inside rim and a second outside rim. The inside rim includes a typical hub plate construction for attachment of the rim to the axle of a vehicle such as a tractor. The outside rim includes a plurality of circumferentially spaced plates projecting laterally, outwardly from the side of the outside rim. A closed circular ring member interconnects the plates. A plurality of openings are defined in the ring. Fastening bolts and nuts connect the hub plate of the inside rim to the ring member associated with outside rim and maintain the plate members in tight, locking communication with the inside rim.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
152 words
An improved dual wheel construction for vehicles comprising, in combination: a first hub assembly having a hub plate for attachment to an axle of the vehicle and a generally cylindrical rim mounted on the hub, said rim including a circular side flange; a second separate generally cylindrical rim including one side in opposed relation with the side flange of the first rim; a plurality of separate, projecting spacer plates attached to and extending laterally from the one side of the second rim, each plate having an unattached end coincident generally with a circle having the axis of said second rim, said second rim also including a closed, circular ring member connected along one edge to the plates; and means for connecting and fastening the ring member with the hub assembly of the first rim to thereby hold the unattached ends of the plates against the circular side flange of said first rim.
Claim 2
Dependent Claim
152 words
An improved dual wheel construction for vehicles comprising, in combination: a first hub assembly having a hub plate for attachment to an axle of the vehicle and a generally cylindrical rim mounted on the hub, said rim including a circular side flange; a second separate generally cylindrical rim including one side in opposed relation with the side flange of the first rim; a plurality of separate, projecting spacer plates attached to and extending laterally from the one side of the second rim, each plate having an unattached end coincident generally with a circle having the axis of said second rim, said second rim also including a closed, circular ring member connected along one edge to the plates; and means for connecting and fastening the ring member with the hub assembly of the first rim to thereby hold the unattached ends of the plates against the circular side flange of said first rim.
Claim 3
Dependent Claim
126 words
In a dual wheel construction of the type including first and second separate rims, one of the rims including a hub assembly for attachment to an axle, said hub assembly including a plurality of fastening means for attaching a hub plate to the one rim, the improvement comprising, in combination: a plurality of separate, circumferentially arranged plates fixed to the other rim and projecting laterally therefrom toward the one rim, said plates being spaced about the circumference of the other rim and having unattached projecting ends; a closed circular ring member having one edge connected with all of the plates; and means for connecting the ring member with the fastening means and simultaneously maintain the projecting ends of the plate in contact with the one rim.
Claim 4
Dependent Claim
126 words
In a dual wheel construction of the type including first and second separate rims, one of the rims including a hub assembly for attachment to an axle, said hub assembly including a plurality of fastening means for attaching a hub plate to the one rim, the improvement comprising, in combination: a plurality of separate, circumferentially arranged plates fixed to the other rim and projecting laterally therefrom toward the one rim, said plates being spaced about the circumference of the other rim and having unattached projecting ends; a closed circular ring member having one edge connected with all of the plates; and means for connecting the ring member with the fastening means and simultaneously maintain the projecting ends of the plate in contact with the one rim.
Claim 5
Dependent Claim
32 words
The improved dual wheel construction of claim 2 wherein said ring member comprises a plate member extending perpendicular from said plates and generally perpendicular to the axis of rotation of said rim.
Claim 6
Dependent Claim
25 words
The improved dual wheel construction of claim 2 wherein said ring member includes a plurality of uniform, spaced openings for cooperation with the fastening means.
Claim 7
Dependent Claim
43 words
The improved construction of claim 2 wherein said means for connecting and said fastening means comprise a combination eye and hook attached to the hub plate and said one rim at one end and attached to the ring member at the opposite end.
Claim 8
Dependent Claim
23 words
The improved construction of claim 2 wherein the ring member is positioned on the inside of the cylinder defined by the spacer plates.
Claim 9
Dependent Claim
38 words
The improved constructional claim 2 wherein said plates are spaced a distance equal to or greater than the circumferential width of said plates whereby dirt does not clog the space between separated dual wheels and a connecting rim.
