  • Mobile vacuum system
    Patent number: 10844574
    Abstract: A system for controlling pressure to a vacuum tank. The system comprises a conduit disposed between the vacuum tank and a blower. The conduit has a sealable connection disposed along its length between two sections that are geometrically conforming. The connection may be conical and threadless. Tilting the vacuum tank relative to the blower causes the connection to separate, allowing pressure within the vacuum tank to equalize with atmospheric pressure. Filters may be provided on each side of the connection for removing particulates from air evacuated from the tank.
    Type: Grant
    Filed: May 11, 2018
    Date of Patent: November 24, 2020
    Assignee: The Charles Machine Works, Inc.
    Inventors: David A. Bural, Levi J. Krutzfeldt, L. Shane Ingram, Vernon T. Stellman
