Abstract

A method and apparatus for installing a plurality of coated steel belts as tension members for an elevator system. A dispenser is employed that retains a plurality of rolled steel belts aligned vertically in said dispenser. An axel passing through the side walls of the dispenser and the centers of the steel belts rolls contained therein rotatably supports the steel belt rolls. When employing the disclosed method, equal lengths of the belts are pulled from the dispenser and clamped between two metal plates. A guide is then connected to the clamped plates which is used to feed the secured coated steel belts down the elevator shaft, around the sheave mechanism and back up the elevator shelf. The center core of the dispenser allows for the even systematic dispensing of steel belts so that equal lengths of the steel belts are fed simultaneous throughout the elevator system.

7. The method of installing a plurality of coated steel, belt tension members for an elevator system according to claim 6, wherein a circular, parallel perforation is contained in each side panel so that when each side panel perforation is removed opposing parallel holes are formed in each side panel wherein a cylindrical axis may be passed through one hole, through the inner recess of said retaining means and through the hole in the opposing side panel whereby the ends of said cylindrical axis are rotatably supported by the side panels.

8. The method of installing a plurality of coated steel belt tension members for an elevator system according to claim 7, wherein an individual coated steel belt is rolled so as to have an unencumbered center whereby said cylindrical axis can be passed therethrough said center of the steel belt roll and said roll is rotatably supported by said axis.

9. The method of installing a plurality of coated steel belt tension members for an elevator system according to claim 8, wherein said individual retaining means have elliptical perforations formed in said front panel of each individual retaining means so that when said perforation is removed, an elliptical slot is formed in said front panel whereby the end of said steel belt can be pulled out of the individual restraining means through the slot of the larger restraining means.

10. The method of installing a plurality of a coated steel belt tension members for an elevator system according to claim 2, wherein said restraining means is composed of reinforced corrugated cardboard.

11. The method of installing a plurality of coated steel belts as tension members in an elevator system according to claim 10, wherein said restraining means is composed of plastic corrugated cardboard.

12. The method of installing a plurality of coated steel belts as tension members in an elevator system according to claim 10, wherein further comprising handle means incorporated in one of said panels of said restraining means.

13.
