First Claim
Patent Images
1. An aramid-based elevator rope and termination device comprising:
- a socket having a longitudinal tapered passageway extending from a rear opening to a front opening, the passageway defined by first and second semi-cylindrical rope engaging surfaces converging toward one another, and transverse walls between the rope engaging surfaces, the first and second semi-cylindrical rope engaging surfaces have a constant radius of curvature;
a wedge disposed within and being of substantially the same shape as the tapered passageway, the wedge having a large end, a small end, and first and second linear portions between the large and small ends;
the wedge comprising a peripheral groove having a variable of radius of curvatures;
the first semi-cylindrical rope engaging surface of the socket and the first linear portion of the wedge defining a first passage having an oblong cross section, the second semi-cylindrical rope engaging surface of the socket and the second linear portion of the wedge defining a second passage having an oblong cross section; and
an aramid-based elevator rope for suspending an elevator having a first length in the first passage, a second length in the second passage and a third length in the peripheral groove around the large end of the wedge, the first and second passages applying a substantially constant force on the cross-section of the first and second lengths of rope, respectively, and the cross-section of the first and second lengths is oblong corresponding to the shape of the first and second passages.

Abstract
A termination device for an aramid-based elevator rope comprises a socket having a tapered internal passageway adapted to receive a wedge and a rope. The passageway has first and second semi-cylindrical rope engaging surfaces. The wedge has a peripheral groove having a variable radius of curvature. The device clamps the length of rope between linear portions of the wedge and the rope engaging surfaces of the socket with a substantially uniform application of force on the cross-section of the rope.
