Patent number: 6672013Abstract: An improved method for mounting elevator rails within a hoistway includes the initial step of securing support brackets to a pair of rails. The brackets, rails, a machine for driving a cab and a dead end hitch are then mounted within the hoistway. A cab may then be moved vertically within the hoistway and additional support brackets are placed at vertically spaced locations. The connection of the brackets and rails provides support to dissipate the loads which are transferred into the rail in such systems wherein the machine or the dead end hitch is fixed to a rail. Once the rails have been adequately supported by additional brackets, the brackets which are secured to the rails are removed from the rail. The brackets provide support, but are no longer fixed to the rails.Type: GrantFiled: November 2, 2000Date of Patent: January 6, 2004Assignee: Otis Elevator CompanyInventors: Thomas E.

Patent number: 5848670Abstract: Apparatus for lifting a wafer, or other such workpiece, from the surface of pedestal in a semiconductor wafer processing system. More specifically, the apparatus relates to a lift pin that is guided by a guide bushing and a guide pin. Preferably, the lift pin is hollow and is slideably engaged with a guide pin. The guide pin is fixed relative to the pedestal and coaxially aligned with a lift pin bore in the pedestal. An actuator drives the lift pin along the guide pin from a fully retracted lift pin position to a fully extended lift pin position. A guide bushing, located in the pedestal proximate the lift pin, also guides the lift pin as the pin passes through the lift pin bore. The guide bushing forms a lip seal between the lift pin and the pedestal. Furthermore, a bellows surrounding the lift pin and the guide pin, can also be used to preserve the integrity of the chamber environment.Type: GrantFiled: December 4, 1996Date of Patent: December 15, 1998Assignee: Applied Materials, Inc.Inventor: Phil Salzman

Patent number: 5845745Abstract: A cable drum type elevator system for residential low-rise use. The elevator includes: a vertically extending support-rail system, an elevator cab mounted thereon for vertical movement, lifting machinery mounted to the support-rail system and cables operated by the lifting machinery and secured to the cab for raising and lowering the cab on the support-rail system. The support-rail system is supported at its lower end and secured to a ground position. A foot assembly is secured to the rail support system and to the ground to cooperate in supporting the support rail system. The foot assembly extends below the elevator cab. The lifting machinery is mounted to the support rail system at its upper end. A dampening system is used in the lifting machinery connection to the support-rail system to minimize system vibration due to the machinery.Type: GrantFiled: October 30, 1996Date of Patent: December 8, 1998Assignee: D.A. Matot, Inc.Inventor: John R. Lane

Patent number: 5725074Abstract: An appendable elevator system includes an elevator car guide structure having two column-like guide modules (10) on which a self-propelled car (5) runs. The guide modules (10) are constructed as a plurality of extruded lightweight metal tubular sections including planar running surfaces (16, 25, 29, 30) for contact with guide rollers (9) and wheels (7, 8) of the car (5), anchoring grooves (33, 34, 35, 36), guide grooves (31, 32) and a brake arm (37) formed on an exterior thereof. An interior of the guide module (10) receives a counterweight (18) guided by the guide grooves (31, 32) and a buffer (44, 45, 46) and is accessible for assembly and maintenance through a removable maintenance lid (43). The sections of guide modules (10) are connected with one another and with a foundation module (12) and with a shaft head module (13) by groove strips (40), connecting straps (41) and screws (42) which engage the anchoring grooves (33, 34, 35, 36).Type: GrantFiled: May 13, 1996Date of Patent: March 10, 1998Assignee: Inventio AGInventors: Utz Richter, Christoph Liebetrau

Patent number: 5690190Abstract: An overlay for a elevator guide rail extends over the joints between segments to provide a seamless engagement surface for the guide rail. The overlay separates the engagement surface from the joints between adjacent segments to minimize vibration and improve the comfort of the ride. In one embodiment, an elevator includes a guide rail having a support formed from multiple segments joined end to end and an overlay encompassing a portion of the support. The overlay defines the engagement surface for the guide shoes of the elevator.Type: GrantFiled: July 5, 1996Date of Patent: November 25, 1997Assignee: Otis Elevator CompanyInventor: James A. Rivera

Patent number: 5609225Abstract: An apparatus for limiting the oscillation amplitude of elevator suspension and compensation elements in an elevator system. The elevator system includes a counterweight movable in guide rails with a suspension element connected to a top of the counterweight and a compensation element connected to a bottom of the counterweight. One or more limiting frames may be employed in the elevator system and each limiting frame surrounds each of the counterweight, guide rails, suspension elements, and compensation elements. Each limiting frame may be attached to the guide rails to limit lateral deflections of the suspension and compensation elements. The limiting frame may include two separate portions which are spring biased together on a stop portion located behind the guide rails, such that excessive deflection of the suspension and compensation elements cause the spring biased portions to separate and activate a safety switch.Type: GrantFiled: April 25, 1995Date of Patent: March 11, 1997Assignee: Inventio AGInventors: Miles P.
