Abstract: Disclosed are apparatus for a block and tackle window balance to be incorporated in single and double hung window assemblies. In one embodiment the block and tackle window balance includes a roller secured within a bottom guide to increase range of travel of a window sash.

Abstract: The present invention relates to inertial braking system for spring-loaded devices, such as block and tackle window balances incorporated in single and double hung window assemblies. In one embodiment, a block and tackle window balance includes a translatable block assembly disposed in a track including a pawl pivotally attached to the translatable block assembly. The pawl, in response to a rapid acceleration of the translatable block assembly, rotates about a pivot and frictionally engages the track, thereby wedging the translatable block assembly in the track. In another embodiment, the translatable block assembly includes a cam attached to the pawl and a brake shoe disposed between the cam and a cord seated within a pulley. Rotation of the pawl causes the cam to translate the brake shoe, thereby compressing the cord against the pulley.

Abstract: Pile weatherstripping (20) having an integral fin is made by wrapping a fin material around a traveling mandrel or band (14), winding pile material around the fin material and the band (14), attaching a pair of backer elements to the pile material along opposite edges of the band, and then cutting the fin material and the pile material to produce simultaneously two pile weatherstrips. Stationary and traveling elements may be employed to facilitate cutting and produce fin above the pile weatherstrips (20).

Abstract: Two pieces of weatherstripping are spliced together by cutting a defined amount of a sealing element from a first piece of weatherstripping leaving an exposed backing, then overlapping a second piece of weatherstripping over the exposed portion of backing of the first piece of weatherstripping, and then ultrasonically welding the backing of the first piece of weatherstripping to the backing of the second piece of weatherstripping.
