Abstract

See full text

A spring wiper for curl springs contained within curl spring mounts, holders or shoes operatively engaged with window sashes that are located in window shoe channels. The spring wiper is deployed on the curl spring holder or mount and contains a wiper blade that is transverse to the curl spring, spanning its width, in order to wipe or scrape debris clinging to and/or accumulated on the surface of the curl spring exposed to airborne particulate matter when the curl spring is extended prior to its being retracted into the curl spring mount or holder, thereby keeping such debris from entering the inside of the curl spring mount or holder and interfering with the continued fluid operation of the sash.
