Patent number: 4070071Abstract: A removable track for an annular resilient tire having a plurality of elongated transversely extending traction shoes mounted on a belt at spaced-apart positions along the belt. Each of the shoes has a plurality of raised traction bars at the end portions of the shoes and a central raised traction bar at a central portion of the shoe. The traction bars extend generally in a direction from one end of the shoe to the other end with the end bars being positioned on the shoe at a distance from a side edge less than the distance of the central bar from the side edge to provide a flex area for cleaning of the shoes. The traction bars at the ends of the shoes may include transverse bars to reinforce the ends of the shoes and angular bars at an acute angle to the side edges to provide traction in the lateral direction.Type: GrantFiled: February 9, 1976Date of Patent: January 24, 1978Assignee: The Goodyear Tire & Rubber CompanyInventor: Vito A. Caravito

Patent number: 4069359Abstract: A plurality of lengths of at least one flattened flexible polymeric tube disposed in superposed relation. Each length in cross section includes enlarged folded edge portions with a flat center portion between the edge portions. Means such as a separator or spacer having substantial thickness is inserted between or within the tube lengths to support the weight of at least a substantial part of the center portion of each length to prevent the formation of edge creases longitudinally along the edges of the tube lengths. The invention is particularly useful in the processing of uncured or unvulcanized rubber tubes either in a stacked or rolled condition.Type: GrantFiled: June 14, 1976Date of Patent: January 17, 1978Assignee: The Goodyear Tire & Rubber CompanyInventors: Ernest W.

Patent number: 4046428Abstract: An elongated resilient sealing strip for sealing the space between a pair of adjacent articulated traction shoes of a removable track for tires having a flexible belt on which the shoes are mounted. The sealing strip has a base with edge portions located between the shoes and belt. In addition, a rib extends from the base into engagement with the surface of at least one of the shoes. The sealing strip may have an edge portion clamped between one of the shoes and the belt, or an edge portion may be adhered to a surface of one of the traction shoes. The rib may extend from the base at an angle to the belt-engaging surface and having a sealing edge engageable with the surface of one of the shoes.Type: GrantFiled: January 5, 1976Date of Patent: September 6, 1977Assignee: The Goodyear Tire & Rubber CompanyInventor: John R. Bauer

Patent number: 4041789Abstract: A belt drive including a toothed power transmission belt and toothed pulley or pulleys operating in conjunction and each having an improved tooth configuration. Each belt tooth as viewed in longitudinal cross-section includes stress relieving portions or fillets adjoining the opposite sides of the base of the tooth. Each fillet has an outer perimeter or outer surface area which is at least 30% of one half of the total outer perimeter or outer surface area of the belt tooth. The pulley in cross section includes an outermost portion having an arcuate outer perimeter formed by the arc of at least one circle whose center point lies within the pulley tooth with one half of the arcuate outer perimeter or outer surface area being at least 30% of one half of the total outer perimeter or outer surface area of the tooth.Type: GrantFiled: December 18, 1975Date of Patent: August 16, 1977Assignee: The Goodyear Tire & Rubber CompanyInventor: Ronald D. Hoback

Patent number: 4037485Abstract: A belt drive and belt and pulleys therefor in which a toothed power transmission belt operates in conjunction with toothed pulleys. The dimensional relationship between the belt teeth and pulley teeth is such that in the longitudinal extent of the belt between the pulleys the height of the belt teeth is greater than the height of the pulley teeth or depth of the pulley grooves while as the belt travels around the pulleys the extreme outwardly facing portions or outer extremities of the belt teeth contact the bottom of the pulley grooves and at the same time the belt teeth are compressed to reduce their height so that the extreme radially outwardly facing portions or outer extremities of the pulley teeth come in contact with the bottoms of the belt grooves. The invention is particularly useful in a synchronous or positive drive system for increasing belt life by relieving stresses on the tensile member in the area between teeth of a positive drive power transmission belt.Type: GrantFiled: December 18, 1975Date of Patent: July 26, 1977Assignee: The Goodyear Tire & Rubber CompanyInventor: Ronald D. Hoback

Patent number: 4029139Abstract: A radial ply tire and rim assembly in which the rim has an axially extended flange with a special configuration to provide a double register for the bead area. 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 and the carcass curves axially inwardly to meet the bead core at a very small angle with respect to the axis of the tire.Type: GrantFiled: January 5, 1976Date of Patent: June 14, 1977Assignee: The Goodyear Tire & Rubber CompanyInventor: John R. Abbott

Patent number: 4019939Abstract: The invention concerns a process for the manufacture of textile or wire-reinforced hoses, the components of which are placed while the inner tube is supported by a mandrel.According to this invention, the mandrel is made of a congealable fluid which is introduced inside the tube and then cooled and solidified during manufacturing steps wherein the formed assembly will resist mechanical stresses which would not be endured by the sole constituents of the hose. The mandrel is thereafter brought back to a liquid form to be drained off.The invention is applicable to the manufacture of medium and high pressure hoses.Type: GrantFiled: August 28, 1975Date of Patent: April 26, 1977Assignee: The Goodyear Tire & Rubber CompanyInventors: Jean Barbier, Paul Cachon

Patent number: 3990324Abstract: An improved vibration damper for use with oscillating bodies and the method of making said damper. The damper includes an inner core member or hub, an outer inertia mass member or inertia ring surrounding and spaced from the hub, and compressible resilient damping means such as a layer of compressible elastomeric material under a limited compression and a retaining means such as a metallic band disposed between the core member and the inertia member. The damping means is chemically adhered to both the retaining means and the core member or the inertia member and the retaining means is fixed in an interference fit to either the outer peripheral surface of the core member or the inner peripheral surface of the inertia member. The damper is particularly useful for mounting on the end of a crankshaft of an internal combustion engine.Type: GrantFiled: December 26, 1974Date of Patent: November 9, 1976Assignee: The Goodyear Tire & Rubber CompanyInventors: Byron L. Fishbaugh, Harold E. Keller, Lionel G. Stewart

Patent number: 3948113Abstract: A belt of integral unitary construction for transmitting power at low tensions and the method of making the belt. The belt includes a continuous body having top and bottom surfaces which are equally spaced apart across the width and throughout the continuous length thereof. The body comprises a neutral axis section extending throughout the length of the belt with a tension section on one side thereof extending toward the top surface of the belt and a compression section on the other side thereof. The tension section extends transversely across the entire width of the belt and at least one groove is provided in the compression section extending from the bottom surface through the compression and neutral axis sections into a portion of the tension section to form a plurality of power transmitting ribs extending longitudinally of the belt to provide a tension section, compression section, and neutral axis in each individual rib.Type: GrantFiled: November 29, 1974Date of Patent: April 6, 1976Assignee: The Goodyear Tire & Rubber CompanyInventor: Delyn M. Stork
