ABSTRACT:
An adjustable-slope torque bracket which includes an annular ramp support for holding multiple triangularly shaped camming ramps. The annular support includes a squared "U" shaped annular recess which opens in the direction of the axis of rotation of the annular support. Each of the triangular shaped camming ramps has a base portion which is shaped to fit within the annular recess. The base portion is raised slightly from the bottom of the recess and pinned between the inner and outer walls of the recess by an axle positioned adjacent one end of the base. The other end of the base is free to move relative to the bottom wall of the annular recess when the camming ramp pivots about the axle. An adjusting bolt is threadably inserted through the free end of the camming ramp and is of sufficient length to abut the bottom wall of the annular recess to raise or lower the free end of the base portion relative to the bottom wall of the annular recess. This adjusting bolt is used to adjust the slope of the camming ramp relative to the annular support ring.
