  • Patent number: 7267372
    Abstract: Tube connectors and tube connector systems are provided. An exemplary system includes a first sleeve, a second sleeve, and radially compressible ring. A tube fits radially inside of the ring and the first and second sleeves. As the first and second sleeves are coupled and brought closer together, inner surfaces of the sleeves exert a radial force onto the ring, causing the ring to radially compress onto the tube.
    Type: Grant

  • Publication number: 20030071461
    Abstract: A tube connecting system and apparatus directed to connecting a tube to a cylinder are provided. A system includes a first sleeve, a second sleeve, a radially compressible ring, and a radially compressible tube. The tube fits radially inside of the ring and the first and second sleeves. As the first and second sleeves are coupled and brought closer together, inner surfaces of the sleeves exert a radial force onto the ring, causing it to radially compress onto the tube, which compresses in response. Contact surfaces may be added to one or both of the sleeves for axially compressing the tube.

  • Patent number: 5435610
    Abstract: The device and method of the invention enables a single workman to drive a tongue and groove subflooring panel into mating connection with a prelaid subfloor panel without the use of a sledgehammer. The device fits over and receives and is secured to the usual driving plank as an operative part thereof. An elongate handle extends upwardly and backwardly at an acute angle to and from its lower end portion, which is fastened to the upper face of the plank centrally and transversely thereof so the workman standing on the panel facing forwardly with his legs spread apart longitudinally therealong uses his weight to flatten the panel while he forcefully pulls the device backwardly, so the driving plank, whose rearward longitudinal edge face abuts the grooved forward edge face of the subfloor panel to be driven, drives such subfloor panel into mated connection with a rearwardly positioned, prelaid, subfloor panel.
