Patent number: 7766308Abstract: A theater rigging assembly having a beam, which is attached to structural support members of a theater or other performing arts venue. The assembly further includes a winch assembly and head block that can be positioned at any point along the beam and selectively fixed in position. The winch portion includes cables for raising and lowering battens or other loads. The head block includes head sheaves, which redirect the cables to loft sheaves that are selectively attached to the beam. The head sheaves are diagonally displaced to separate the cables. The winch portion includes a motor, a gear box, a drum and a brake. The brake includes a ratchet and two brake disks. It uses at least one friction surface that contacts at least one of the brake disks to cause a pawl to engage or disengage from the ratchet.Type: GrantFiled: February 10, 2009Date of Patent: August 3, 2010Assignee: J. R. Clancy, Inc.Inventors: Stephen J. Kochan, Peter V. Svitavsky, Thomas J. Walsh, III, Thomas S. Young

Patent number: 7343958Abstract: A garage door cable drum is disclosed for a sectional overhead door of a type having a substantially non-linear lift-weight to lift-height characteristic. The drum includes a generally spiral cable groove having a variable minor radius. The groove minor radius at any intermediate point along the groove is sized to provide a lift-cable moment arm that yields a corresponding cable lift force that is slightly less than an instantaneous lift weight of the garage door at any intermediate door elevation.Type: GrantFiled: April 4, 2005Date of Patent: March 18, 2008Assignee: Amarr CompanyInventors: A. Anthony East, Darrin Brunk, Yannick Funk, Normand Savard, Mathieu Provencal

Patent number: 6643979Abstract: A window regulator assembly is provided that includes a guide defining a path. A window bar assembly having a window mounted thereon is supported on the guide and is movable along the path. A manual or automatic actuator is interconnected with a drum for rotationally driving the drum. A pair of cables each include an end connected to the drum with the opposing end connected to the guide. The cables are arranged in a pull-pull relationship between the drum and guide. A portion of the cables is wrapped about the circumference of the drum. A drum biasing assembly, which may include a mandrel urged into bore of the drum by a spring, expands the circumference of the drum to take up the slack in the cables. The drum includes radial grooves that divides the drum into sectors that are movable relative to one another by the mandrel.Type: GrantFiled: February 11, 2002Date of Patent: November 11, 2003Assignee: Meriton Light Vehicle Technology, LLC.Inventor: Stanley Schlatter

Patent number: 6601794Abstract: A cable drum, having a substantially cylindrical drum body with drum walls arranged at its axial ends and a groove arrangement arranged on the drum body, enables winding of a cable in a rotational direction clockwise as well as counter-clockwise thereto. The groove arrangement has parallel areas in which the grooves are parallel to the circumferential direction and incline areas in which the grooves are slanted at an angle relative to the circumferential direction of the drum body. All grooves in the parallel areas have identical groove width. The grooves in the incline areas cross one another.Type: GrantFiled: June 21, 2002Date of Patent: August 5, 2003Assignee: Rotzler GmbH & Co. KGInventor: Ralf Brutschin
