Abstract
Abstract The invention provides a method of reinforcing a solid tire mounted upon a cylindrical hub such as, for example, a solid rubber fork lift truck tire. Tires have a solid flexible outer layer bonded to an inner cylindrical metal band. The hub is press fit within the band. In order to increase lateral stability or traction, operators often install tires of width greater than the size for which the hub is designed. The unsupported periphery of the band is subjected to impact loads and premature tire failure occurs. The invention provides a removable reinforcing ring which is press fit within the inner cylindrical surface of the metal band adjacent the hub. The outer cylindrical surface of the ring is of diameter to securely engage the band in operation but may be removed and reinstalled during normal maintenance by the same press which separates the tire and hub.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
129 words
A method of reinforcing a solid tire mounted upon a cylindrical hub, the hub being of a width less than the width of the tire, the tire including an outer peripheral solid flexible layer bonded to an inner cylindrical metal band of a width substantially equal to the width of the tire, the outer cylindrical surface of the hub being press fitted within the inner cylindrical surface of the metal band, said method comprising press fitting a removable reinforcing ring within the inner cylindrical surface of the metal band adjacent the hub, the ring having an outer cylindrical surface of a diameter to securely engage the band in operation and a width substantially equal to the difference between the width of the band and the width of the hub.
Claim 2
Independent Claim
129 words
A method of reinforcing a solid tire mounted upon a cylindrical hub, the hub being of a width less than the width of the tire, the tire including an outer peripheral solid flexible layer bonded to an inner cylindrical metal band of a width substantially equal to the width of the tire, the outer cylindrical surface of the hub being press fitted within the inner cylindrical surface of the metal band, said method comprising press fitting a removable reinforcing ring within the inner cylindrical surface of the metal band adjacent the hub, the ring having an outer cylindrical surface of a diameter to securely engage the band in operation and a width substantially equal to the difference between the width of the band and the width of the hub.
Claim 3
Dependent Claim
126 words
A removable reinforcing ring for tires, the tires being press fit mounted upon a cylindrical hub of a width less than the width of the tire, the tire including an outer peripheral solid flexible layer bonded to an inner cylindrical metal band of a width substantially equal to the width of the tire, the outer cylindrical surface of the hub being press fitted within the inner cylindrical surface of the metal band, said ring having an outer cylindrical surface of a diameter to securely engage the band in operation and a width substantially equal to the difference between the width of the band and the width of the hub, the ring being press fit within the inner cylindrical surface of the metal band adjacent the hub.
Claim 4
Dependent Claim
126 words
A removable reinforcing ring for tires, the tires being press fit mounted upon a cylindrical hub of a width less than the width of the tire, the tire including an outer peripheral solid flexible layer bonded to an inner cylindrical metal band of a width substantially equal to the width of the tire, the outer cylindrical surface of the hub being press fitted within the inner cylindrical surface of the metal band, said ring having an outer cylindrical surface of a diameter to securely engage the band in operation and a width substantially equal to the difference between the width of the band and the width of the hub, the ring being press fit within the inner cylindrical surface of the metal band adjacent the hub.
Claim 5
Dependent Claim
25 words
A ring according to the claim 2, wherein the inward portion of the outer cylindrical surface of the ring adjacent the hub is tapered radially.
Claim 6
Dependent Claim
17 words
A ring according to claim 2, wherein the ring, when installed within the band, abuts the hub.
Claim 7
Dependent Claim
13 words
A ring according to claim 2, wherein the ring is of solid cross-section.
Claim 8
Dependent Claim
14 words
A ring according to claim 5, wherein the ring is substantially rectangular in cross-section.
Claim 9
Dependent Claim
11 words
A ring according to claim 2 wherein the ring is metal.
