    Abstract: An escalator combplate is equipped with a stop switch that will interrupt the power to the escalator when objects trapped between the stop treads and combplate impose a predetermined lifting force on the combplate. The necessary lifting force is determined by code requirements, and the combplate is subjected to an upward spring force which equals the code-dictated lifting force. While the combplate is being lifted by the spring force, the stop switch or switches are set so that they will actuate at the calibrated position of the combplate. The spring force is then removed to allow the combplate to settle back to its normal operating position.

    Abstract: The moving handrail on an escalator or moving walkway is first tightened on its guide rail to the extent necessary to eliminate substantially all handrail slack in the handrail loop. Thereafter, the handrail is loosened so as to impart optimum slack thereto whereby handrail friction and heat is minimized during operation of the escalator or moving walkway.

    Abstract: The handrail drive is a mangle-type drive wherein the handrail passes through the nip of a pair of opposed drive rollers. A plurality of drive roller pairs may be used. The drive rollers are keyed to rotatable shafts to which drive sprockets are also keyed. The drive sprockets are rotated by an endless chain which in turn is driven by one or more powered sprockets. The drive roller shafts are journaled in rotatable bearings which are mounted in a mechanism housing with the bearings being eccentrically mounted in the housing with respect to the drive roller shafts. The housing is divided into two halves, each mounting one of the rollers in a drive roller pair. The two housing halves are hinged together so that the nip of each drive roller pair can be opened by pivoting one half of the housing away from the other half of the housing. When the drive rollers are rotated, friction between the handrail and the drive rollers, and between the roller shafts and eccentric bearings will cause the bearings to rotate about their axes thereby tightening the drive rollers about the handrail. As handrail drive roller friction increases, the tightening effect also increases. The rollers will only tighten on the extent needed to overcome the friction between the handrail and its guide rail. When the drive mechanism is turned off, the drive rollers only lightly engage the handrail.

    Abstract: A pitless elevator system removes a car buffer and machine, and other components where so equipped from under the elevator car such that the elevator car can be operated to a clearance between it and a floor of a hoistway of about three inches. The machine may be mounted on board the car or may be located elsewhere and the car buffer located in normal side clearance space. The system further provides a retractable toe guard to allow the car to bottom at the indicated distance from the floor. The system facilitates retrofit applications of elevators without the prior art drawback of digging a pit.

    Abstract: A motor secondary in a linear induction motor used for opening and closing doors in an elevator system includes a secondary guide system having a first secondary guide and a second secondary guide. The first secondary guide is disposed on a bottom longitudinal edge of the motor secondary and the second secondary guide is disposed on a top longitudinal edge of the motor secondary. The guides space apart the motor secondary from the motor primary and establish small and constant running clearances therebetween.

    Abstract: A power switch assembly is operably connected to the combplate of an escalator for selectively shutting off the escalator in the event of entrapment of some object between the steps and combplate. When an object becomes wedged between the steps and combplate, the latter will be lifted or pushed upwardly away from the steps. The upward movement of the combplate operates a power interruption switch to stop further movement of the steps and handrail. The combplate is supported on the truss by spring assemblies which serve to effectively lower the weight of the combplate so that upward movement of the latter is more readily accomplished. The assembly can be retrofitted onto older existing escalators with heavier combplates than are found in newer equipment.

    Abstract: A moving handrail on an escalator or the like is driven by pairs of rollers which form a nip through which the handrail moves. The rollers are eccentrically mounted so as to automatically tighten the nip in response to resistance to movement of the handrail. The roller or rollers which contact the underside of the handrail are rotatably driven by power sprockets, while the roller or rollers contacting the outer or exposed surface of the handrail are idler rollers which are not rotated by the power sprockets so as to lessen scuffing of the exposed surface of the handrail by the rollers.

    Abstract: The underside of an escalator or moving walkway handrail is continuously cleaned by an assembly which includes rotating brushes associated with a vacuum nozzle which removes loosened debris from the handrail. The brushes are preferably driven so as to rotate in opposite directions to sweep debris toward the vacuum nozzle. The vacuum nozzle empties into a container which can be periodically emptied during normal servicing of the escalator or walkway.
