Patent number: 4235271Abstract: A removable resilient shield is maintained proximate the sidewall of a tire for off-the-road vehicles to protect this critical area of the tire from damage due to contact with external objects such as rocks. The shield is secured to the terminal portion of the rim flange. The radially inner portion of the shield is spaced axially of the rim and at least one radially extending passage is provided for removal of debris from between the shield and the sidewall of a tire mounted on the rim.Type: GrantFiled: July 13, 1979Date of Patent: November 25, 1980Assignee: The Goodyear Tire & Rubber CompanyInventors: Richard J. Olsen, George T. Watts, Robert I. Griffiths

Patent number: 4230511Abstract: An endless tread assembly is fabricated on a ring having grooves and ridges which mold the radially inward surface of the tread assembly. The ring is a thin walled cylinder having a single slit or gap. The tread assembly on the ring is suspended by rotatable wheels rollable on the inward surface of the ring, so as to position an arcuate portion of the ring and tread assembly between a fixed press arm and a single movable heated press mold shoe operable to mold about a 40 degree arc of the tread assembly between the shoe and the ring backed by the press arm. Lugs on the inward surface of the ring cooperate with a latch fixed on the press arm to index selected increments of the tread assembly and ring between the press arm and mold segment. After all arcuate increments of the tread assembly have been molded and cured, the ring is opened at the gap and then simply flexed to reduce its diameter sufficiently to remove the cured tread assembly.Type: GrantFiled: January 24, 1979Date of Patent: October 28, 1980Assignee: The Goodyear Tire & Rubber CompanyInventor: Richard J.

Patent number: 4169877Abstract: The production of a very large tire by expanding the uncured unrestrained carcass of the tire to engage its crown region with the radially inward surface of a rigid circumferentially continuous centering ring. The ring and the uncured carcass together are transported from the carcass expanding location to the tire curing mold which is adapted to receive and locate the ring and carcass together so as to prevent the mid-circumferential region of the carcass from shifting out of symmetry with the mold. The ring forms a part of the mold for molding and curing the tire carcass. The inward surface of the ring is provided with a pattern of grooves and ridges; the method and apparatus disclosed are particularly useful in the manufacture of a cured tire carcass adapted to combine with an endless tread assembly cured apart from and independently of the tire carcass to make the complete tire.Type: GrantFiled: November 13, 1978Date of Patent: October 2, 1979Assignee: The Goodyear Tire & Rubber CompanyInventors: Richard J. Olsen, Max D. Brinkley, John R. Thiele

Patent number: 4096900Abstract: A radial ply tire and rim assembly for use on earthmoving equipment. The rim is of the drop center type having approximately six degree bead seats and an extended conical stabilizer flange. The tire when mounted on the rim and inflated has its carcass distorted radially outwardly from the natural equilibrium curvature in which it was molded.The foregoing abstract is not be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawings and the following detailed description.Type: GrantFiled: January 5, 1976Date of Patent: June 27, 1978Assignee: The Goodyear Tire & Rubber CompanyInventor: Richard J.

Patent number: 4071068Abstract: A removable track belt for installation around the outer surface of a tire carcass has on its inner surface a plurality of circumferential lands and grooves that interlock with lands and grooves on the tire carcass. The inner surface of the track belt also has a plurality of spaced axial grooves for receiving removable rigid keeper bars, to which grousers are attached. The underside of each keeper bar contains lands and grooves that also mate with those of the tire carcass.Type: GrantFiled: January 5, 1976Date of Patent: January 31, 1978Assignee: The Goodyear Tire & Rubber CompanyInventor: Richard J. Olsen

Patent number: 4050495Abstract: A removable tread installed as an annular belt about the circumference of a tire carcass. The inner surface of the removable tread belt and the outer surface of the tire carcass have an interengaging pattern to interlock the two. The removable tread belt has a plurality of axially oriented metal bars and an inextensible circumferential belt radially outwardly of the bars. The bars and the inextensible belt are encapsulated in a matrix of rubber. The ends of the bars extend outwardly to a point beyond the widest portion of the tire carcass sidewall. The tread belt has a tread pattern on its outer circumferential surface.Type: GrantFiled: January 5, 1976Date of Patent: September 27, 1977Assignee: The Goodyear Tire & Rubber CompanyInventor: Richard J. Olsen
