Patent number: 6626573Abstract: A bearing assembly for supporting a drive shaft of a ship wherein the shaft if generally to be supported by such bearing assembly in a horizontally extending position. The bearing assembly has a housing with a cylindrical shell mounted therein having a central bore with a longitudinally extending central axis. The shell has a plurality of circumferentially spaced staves provided therein which project into the central bore to support the drive shaft. The staves have transverse grooves provided therein.Type: GrantFiled: May 4, 2001Date of Patent: September 30, 2003Assignee: Duramax Marine, LLCInventor: Roy Lee Orndorff, Jr.

Patent number: 4036472Abstract: A flat, rectangular, inflatable bag type lifting device includes two rectangular walls interconnected at their marginal portions to enclose an inflation chamber or cavity. Each of the two walls have length to width ratios greater than one and include layers of rubberized mutually parallel cords extending at a preselected acute angle relative to the longitudinal center line of the wall in which they are contained with cords of immediately adjacent layers being in opposite directions. When inflated, the bag reduces in length due to the movement of cords to a larger acute angle and thereby achieves a lift height effective for lifting or jacking up structures such as automobiles.Type: GrantFiled: November 9, 1976Date of Patent: July 19, 1977Assignee: The B. F. Goodrich CompanyInventor: Roy Lee Orndorff, Jr.
