Patent number: 6076586Abstract: The running characteristics of a vehicle wheel with a tire are improved by applying axial pressure with a pressure application ring (26) which temporarily compresses the flanks of a tire (10) to such an extent that a portion of the axially outwardly facing surface of the respective tire bead lifts off from the respective rim flange. This permits the tire bead to press itself, in response to the air pressure in the tire, into the corner formed between a cylindrical portion of the rim and the flange portion of the rim. The ring-shaped pressure application ring (26) comprises a plurality of circumferentially arranged ring sectors (7). These sectors can be adjusted in their radially inwardly or outwardly to thereby adapt the diameter of the pressure application ring for use in connection with a wide range of tire diameters.Type: GrantFiled: January 8, 1997Date of Patent: June 20, 2000Assignee: Schenck Rotec GmbHInventor: Didier Hans

Patent number: 5752555Abstract: A quick release mechanism for the mount/dismount head of a rim holding tire changer, including a wedge plate that overlies the top of the horizontal bar and has an opening in registry with the opening in the sleeve through which the vertical bar passes. The opening in the wedge plate is shaped to mate with the cross-sectional profile of the vertical bar and is only slightly larger than the size of the bar. Thus, when the wedge plate is horizontal so that the axis of the opening is aligned with the axis of the opening of the sleeve, the vertical bar will move freely up and down in response to pressure on the vertical bar. The wedge plate has protrusions on its under side on one side of the opening and the protrusions rest on the upper face of the sleeve. A actuation handle is attached to the underside of the wedge plate and depends perpendicularly from it.Type: GrantFiled: November 1, 1995Date of Patent: May 19, 1998Inventors: Charles L.

Patent number: 5146969Abstract: An apparatus for filling pressurized air into a tire includes a table for supporting thereon a tire mounted on a rim, an inner cylinder member air-tightly engageable with a flange of the rim, and an outer cylinder member air-tightly engageable with a side rubber of the tire and forming an air-tight space in cooperation with the inner cylinder member. The end face of the outer cylinder member air-tightly engageable with the side rubber of the tire is inclined to the rotating axis of the tire. Therefore, the bead portion of the tire needs only to get over the part of the hump of the rim positioned oblique relative thereto along its circumference little by little during filling pressurized air into the tire. As a result, the bead portion of the tire is only subjected to a little deformation and comes into close contact with the rim, the bead portion of the tire substantially uniformly closely contacts the rim.Type: GrantFiled: November 7, 1991Date of Patent: September 15, 1992Assignee: Bridgestone CorporationInventors: Hiroshi Kawabe, Toshiyuki Watanabe

Patent number: 5022451Abstract: Methods of and apparatus for facilitating the inflation of tires mounted on split rims. Gripper devices are fixed to the outer flange ring of the split rim at equidistantly spaced intervals therearound, and generally equal forces are exerted on these devices to pull the bead seat ring of the rim toward the outer end of the rim. This: (1) seats the bead seat ring on an O-ring surrounding the bead seat to keep air from leaking between the bead seat and bead seat ring, and (2) displaces the outer flange ring away from the outer bead of the tire so that the bead can move toward the outer end of the rim and the tire thereby freely expand as air is pumped into the tire.Type: GrantFiled: September 1, 1989Date of Patent: June 11, 1991Inventor: William D. Fenderson

Patent number: 4759395Abstract: The bead breaker for vehicle tires involves a hydraulic jack member whose base is attached to a bead pressing member and whose extendable head is connected by tension members, such as a chain and hook combination, to the wheel. The bead pressing member may have alternative configurations, one being an adjustable split presser assembly comprising a presser arm, attached to the jack base, upon whose opposing extended arms are slidingly mounted adjustable sleeves. Attached to each radially adjustable sleeve is an arcuate presser section which presses downward against the tire bead when the jack head is extended, breaking the bead. In the alternative bead pressing member, the presser arm, attached to the jack base, is removably attached to a ring presser member, which presses against the tire bead along a full 360-degree circumference.Type: GrantFiled: May 27, 1987Date of Patent: July 26, 1988Inventor: Kazuichi Tsukamoto
