Abstract
A tension release mechanism for use with a dancer pulley assembly includes a first horizontal plate having an upper surface and a lower surface, a swing arm having a first end pivotally mounted to the first horizontal plate on the lower surface thereof and being pivotal about a vertical pivot axis A, a second horizontal plate having an upper surface and a lower surface and being spaced vertically above the first horizontal plate by at least one vertical support, a pulley shaft having an upper end and a lower end, the lower end being mounted on the second end of the swing arm and extending upwardly through an arcuate opening formed in the first horizontal plate, a dancer pulley rotatably mounted on the pulley shaft between the first and second horizontal plates for rotation about a vertical rotation axis B and being swingable on the swing arm through an arc defined by a distance between the pivot axis A and the rotation axis B, a guide for guiding the upper end of the pulley shaft during swinging motion of the dancer pulley, and a mechanism for adjusting the guide to maintain a substantially vertical orientation of the rotation axis B.
