-10- TITLE PIVOT SHOE FOR SASH BALANCE ABSTRACT A pivot shoe 10 has a bite spring 30 operated by a cam 40 for interlocking pivot shoe 10 with a jamb channel 15 to resist upward movement under the bias of a sash balance system when a sash 20 connected to pivot shoe 10 by a pivot bar 22 is pivoted away from vertical. Pivot shoe 10 has a resin body 11 shaped to guide on the sides 16 of jamb channel 15 and cam 40 is pivotally housed within body 11 and slotted to receive pivot bar 22 so that cam 40 pivots with sash 20. The jamb end of cam 40 is profiled, and bite spring 30 has a follower 32 engaging the cam profile 47. Bite spring is mounted on the jamb side of pivot shoe 10 and upwardly inclined toward the jamb channel bottom 17. When sash 20 pivots from vertical, cam 40 tilts bite spring 30 outward so that its upper edge bites into channel bottom 17 and locks pivot shoe 10 against upward movement.
