Patent number: 11214465Abstract: A belt for suspending and/or driving an elevator system component include one or more metallic cord tension elements extending along a length of the belt, and one or more non-metallic tension elements extending along a length of the belt. Each non-metallic tension element is formed from a non-metallic material. The one or more metallic cord tension elements and the one or more non-metallic tension elements are arrayed laterally across a lateral width of the belt. The belt may be used in an elevator system including a hoistway, a drive machine having a traction sheave coupled thereto, an elevator car movable within the hoistway. The belt is operably connected to the elevator car and interactive with the traction sheave to suspend and/or drive the elevator car along the hoistway.Type: GrantFiled: December 15, 2017Date of Patent: January 4, 2022Assignee: OTIS ELEVATOR COMPANYInventors: Kathryn Rauss Sherrick, Barry G. Blackaby

Patent number: 10926975Abstract: A belt for suspending and/or driving an elevator car of an elevator system includes a plurality of tension members spaced from each other along a width of the belt and extending longitudinally along a length of the belt. A jacket at least partially envelopes the plurality of tension members and forms at least one outer belt surface along a width of the belt. A groove is located in the at least one outer belt surface extending longitudinally along the length of the belt.Type: GrantFiled: April 1, 2014Date of Patent: February 23, 2021Assignee: OTIS ELEVATOR COMPANYInventors: Brad Guilani, Kathryn Rauss Sherrick

Patent number: 10329121Abstract: A belt and a method for manufacturing a belt is provided. The belt includes a plurality of lengthwise-extending tension members and a jacket. The jacket substantially retains the plurality of tension members. The jacket has a first side region, a second side region, and a center region between the first and second side regions. The first and second side regions of the jacket are more fire retardant than the center region of the jacket.Type: GrantFiled: May 10, 2017Date of Patent: June 25, 2019Assignee: Otis Elevator CompanyInventors: Mark F. Orelup, Brad Guilani, Kathryn Rauss Sherrick, Amir Lotfi, Hong Yang

Patent number: 8734203Abstract: An illustrative method of making a load bearing member for use in an elevator system includes mechanically roughening at least one surface on an exterior of a jacket of the load bearing member to establish a friction characteristic that facilitates engagement between an elevator system sheave and the roughened surface.Type: GrantFiled: May 3, 2013Date of Patent: May 27, 2014Assignee: Otis Elevator CompanyInventors: John T. Pitts, Ary O. Mello, Hugh J. O'Donnell, John P. Wesson, William A. Veronesi, Douglas E. Logan, Mark Steven Thompson, Kathryn Rauss Sherrick, Bill Perron

Patent number: 8449349Abstract: An elevator load bearing member assembly includes at least one roughened surface (46) on a polyurethane jacket (44). In one example, mechanical roughening is used to roughen the surface (46) after the jacket has been extruded onto tension members (42). In another example, the temperatures used for molding a jacket (44) are controlled to induce melt fracture and roughen the surface (46) during the forming process. Other examples include chemically roughening the jacket surface and using localized heating to roughen the surface. The roughened jacket surface improves friction characteristics of a load bearing member assembly.Type: GrantFiled: March 15, 2004Date of Patent: May 28, 2013Assignee: Otis Elevator CompanyInventors: Mark S. Thompson, William A. Veronesi, John Pitts, Ary O. Mello, Hugh J. O'Donnell, John P. Wesson, William C. Perron, Douglas E.

Publication number: 20110114908Abstract: An exemplary method of making a first component for contacting another component includes applying a wear and corrosion resistant material layer onto a surface of the first component. The wear and corrosion resistant material layer is then roughened subsequent to having been applied to the surface. A component comprises an exemplary elevator sheave that includes a metallic body having a sheave surface that is adapted to contact an elevator tension member. A corrosion resistant material layer on the sheave surface has a thickness that is greater than about 5 microns.Type: ApplicationFiled: July 3, 2008Publication date: May 19, 2011Inventors: Richard N. Fargo, Kathryn Rauss Sherrick, David Wayne Mckee, Jon George Demos
