  • Patent number: 6216541
    Abstract: A pressure gauge in which the displacement tip of the Bourdon tube is sealed and secured to a bracket of an amplifier movement by a selected solder composition affording a failure response to an encountered overpressure at a pressure value lower than the burst pressure of the Bourdon tube. Overpressure causes a fracture in the solder to be incurred enabling release of the overpressure while a throttle plug situated in the inlet path to the Bourdon tube severely restricts continuing gas flow to the fracture site. As a consequence, released flow from the solder fracture will be at a pressure insufficient to potentially cause explosion of the gauge case/lens to occur.

  • Patent number: 6182736
    Abstract: A helper arm for use in conjunction with a rim-holding tire changer for assisting with the mounting/demounting of a tire. The helper arm comprises an arm having one end attached to a support device and an opposite end operably attached to an adjustable vertical member. The arm is preferably jointed and pivotally attached to the support device. Controls are provided to enable vertical adjustment of the vertical member. The vertical member may comprise a cylinder assembly having a cylinder shaft that may be moved up or down into operable engagement with the tire and wheel rim. A contact block is attached to the lower end of the cylinder. The contact block includes an attachment head configured to enable attachment of the block to the vertical member. Further, the contact block includes a shoulder having a rim-stop surface, a hook member opposite the shoulder, a heel extending downwardly from the body of the block and an instep along the underside of the block.

  • Patent number: 6062289
    Abstract: A laminated clamp for use in connection with rim holding tire changers. The clamp includes a plurality of pliable gripping plates alternately disposed between a plurality of rigid support plates. The plurality of gripping plates provide multiple surfaces for effectively gripping the rim of a wheel and the support plates provide a rigid support structure for the clamp. The gripping plates are constructed of a material that is capable of gripping the rim without causing damage thereto. The gripping plates and support plates are configured to form claws for gripping the wheel rim from either the outside or the inside the rim. To prevent damage to the wheel, the edges of the gripping plates extend peripherally beyond the edges of the support plates thereby preventing the support plates from contacting the rim when the rim is operably seated in the clamp. Two of the support plates include base portions configured for attachment to the clamp carrier of the tire changer.

  • Patent number: 5941294
    Abstract: A quick change assembly for connecting a mount/dismount head to a swing arm of a rim holding tire changer. The rim holding tire changer includes a swing arm mounted for swinging the mount/dismount head into and out of engagement with a tire on the table of the rim holding tire changer. The quick change assembly is connected to the end of the swing arm. The quick change assembly acts to connect the mount/dismount head to the end of the swing arm in a pre-aligned rotatable orientation. One end of the connector is adapted to mate with the mount/dismount head. That end includes an adjuster for adjusting the aligned relation of the mount/dismount head with respect to the connector end. The other end of the connector includes a locator for locating the pre-aligned rotatable orientation with respect to the swing arm end. Such locator may be a dowel inset in the swing arm end and a slot in the end of the connector which mates to the swing arm. A bore-counter-bore would be sufficient as well.
